I. Yam khoom tiag tiag yog dab tsi
Ua ntej leej twg tuaj yeem soj ntsuam seb puas muaj PVC railing yuav tuav, nws yuav pab kom paub tias cov khoom siv tiag tiag yog dab tsi - vim tias lo lus "yas" nqa lub hnab ntim khoom uas cov khoom siv no tau tso tawm ntau. Niaj hnub nimno PVC railing pib nrog nruj PVC resin, cov tshuaj npe hu ua uPVC - unplasticized polyvinyl chloride, cais nws los ntawm saj zawg zog PVC siv nyob rau hauv cov kav dej thiab hlau jacketing. Nyob rau hauv cov ntaub ntawv no, cov formulation compounder ntxiv cov kev hloov pauv uas nqus lub zog poob siab yam tsis muaj kev tawg, thermal stabilizers uas tiv thaiv cov saw hlau polymer thaum lub sij hawm siab -kub extrusion thiab tom qab ntawd thaum lub hnub raug, UV stabilizers - ua ke ntawm titanium dioxide opacifier, organic UV absorber, thiab cuam tshuam rau hauv cov pigments {6} thiab cuam tshuam rau cov pigments. Cov khoom sib xyaw no tawm ntawm qhov extruder los ntawm qhov profile tuag ntawm kwv yees li 180 txog 200 degrees Celsius, tawm los ua ib qho txuas txuas ntxiv lossis ntau-chamber cov qauv duab uas tau txias, ntsuas, thiab txiav kom ntev.
Cov khoom lag luam uas tau txais daim ntawv lo "premium" ua ib kauj ruam ntxiv: lawv embed aluminium square raj hauv PVC profile - txawm tias yog ib qho txuas mus tas li - ntev tub ntxhais khiav los ntawm ncej hauv paus mus rau lub hau, los yog ua ib qho kev txhawb nqa hauv cov tes tuav sab saum toj. Cov qauv sib xyaw no cais cov dej num: cov txhuas yog khoov lub sijhawm thiab cov khoom thauj sab nraud, thaum lub plhaub PVC tuav cov huab cua raug thiab muab qhov zoo nkauj. Tsis yog cov khoom siv, ib leeg, tuaj yeem xa ob txoj haujlwm. Ua ke, lawv tsim cov railing uas ua tau zoo dua ntoo thiab hlau ntawm kev saib xyuas thaum sib txuam rau ntawm cov qauv rigidity.
Qhov kev cuam tshuam rau tus neeg yuav khoom yog ncaj nraim. Thaum koj ntsib cov khoom siv PVC railing, thawj lo lus nug uas yuav tsum tsis yog "nws raug nqi pes tsawg ntawm ib kab ko taw" tab sis "qhia kuv tus ntoo khaub lig-section." Ib qho kev txiav-tawm ntawm cov khoom siv tiag tiag qhia ntau ntxiv txog cov khoom lag luam engineering hauv tsib vib nas this dua li daim ntawv qhia qhia hauv tsib caug nplooj ntawv. Koj tuaj yeem pom seb cov phab ntsa thickness zoo li cas. Koj tuaj yeem pom seb puas muaj cov tub ntxhais aluminium muaj nyob thiab nws cov phab ntsa tuab npaum li cas. Koj tuaj yeem pom seb cov chav sab hauv yog tsim kom huv si los yog riddled nrog voids los ntawm rushed extrusion kab. Tus neeg muag khoom uas tsis tuaj yeem lossis tsis tuaj yeem muab tus ntoo khaub lig- ntu qauv yog, los ntawm qhov tsis kam lees ib leeg, qhia koj qee yam txog cov khoom.YUPSENI ships cross-section samples with specification sheets for every railing profile in the catalog.
Piv rau ntoo, PVC railing tsis rot, tsis nyiam kab, thiab yeej tsis xav tau ib tug pleev xim rau. Piv nrog rau cov hlau, nws tsis ua cov galvanic corrosion tam sim no, thiab khawb thoob plaws hauv nws qhov chaw tsis nthuav tawm cov hlau nyoos tos kom oxidize. Cov xim yog ib feem ntawm cov khoom nws tus kheej - tsis yog txheej uas tuaj yeem tev. Tab sis txhua qhov txiaj ntsig zoo no nyob ntawm kev tsim thiab cov qauv ua tau zoo- ua tiav thawj qhov chaw. Ib qho kev tsim tsis zoo ntawm PVC railing tseem yuav poob siab; nws yuav cia li poob siab los ntawm ntau hom kev ua tsis tau zoo dua li ntoo lossis hlau.
II. Qhov Wobble Tiag Los Ntawm - Thiab Plaub Qhov Chaw Tshawb Xyuas Ua Ntej Koj Yuav
Ib lub railing uas trembles nyob rau hauv tes siab yog feem ntau unsettling tshaj ib tug uas pom tau tawg. Lub siab sau npe qhov kev vibration raws li kev ceeb toom ua ntej lub qhov muag tuaj yeem nrhiav kev puas tsuaj. Thiab qhov hais txog wobble yog tias cov khoom siv yuav luag tsis yog lub hauv paus ua rau. Ib qho PVC ncej, txawm tias tsis muaj kev txhawb nqa sab hauv, muaj qhov nruj txaus ntawm qhov luv luv los tiv thaiv tes ua haujlwm. Lub wobble nkag los ntawmplaub qhov kev txiav txim tshwj xeeb- Tag nrho cov ntawm lawv ntsuas tau, tag nrho lawv cov ntaub ntawv pov thawj ua ntej ib qho khoom tawm ntawm lub tsev khaws khoom.
Thawj nyob hauv phab ntsa tuab. PVC railing profiles nyob rau hauv qhov zoo tier nqa phab ntsa kwv yees li ntawm ib millimeter thiab ib nrab thiab ob thiab ib feem peb. Cov khoom uas poob hauv qab hauv pem teb yog nyob rau hauv lub vaj zoo nkauj edging, tsis yog nyob rau hauv ib tug guardrail uas tej zaum yuav muaj ib hnub yuav tsum tau ntes ib tug neeg laus stumbling. Kev kuaj xyuas nrawm uas tsis xav tau cov cuab yeej: nias koj tus ntiv tes xoo kom ruaj khov rau hauv nruab nrab ntawm ib qho railing seem. Yog tias phab ntsa deflects nyob rau hauv lub siab ntawd ib leeg, qhov profile yog nyob rau hauv - spec. Ib txoj hauv kev yooj yim dua - thiab ib qho uas cais tus neeg yuav khoom loj los ntawm ib tus neeg sib piv- kev yuav khoom los ntawm tus nqi - yog coj lub caliper digital mus rau lub chaw muag khoom thiab ntsuas tus ntoo khaub lig- ntu ncaj qha.
Tus ntoo khaub lig- ntu qauv thiab lub caliper teb cov lus nug ntau dua hauv peb caug vib nas this dua li cov khoom lag luam tag nrho cov lus teb hauv ib teev. Uniform phab ntsa thickness, huv si chamber tsim, thiab pom txhuas core thickness - tag nrho cov paub tseeb los yog disproven ntawm ib nrais muag.
Post cross-section yog qhov hloov pauv thib ob. Kev lag luam benchmark rau lub ntsiab structural posts zaum ntawm kwv yees li kaum centimeters los ntawm kaum centimeters - paub plaub-los ntawm- plaub. Cov ntawv tshaj tawm uas ntsuas slimmer tshaj qhov xav tau ib qho tseem ceeb ntawm aluminium core raws li qhov tsis yog -kev sib tham. Yog tsis muaj nws, qhov txo seem modulus txhais tau hais tias lateral loads tsim deflection tes yuav hnov. Qhov no tsis yog qhov teeb meem ntawm "hnyav-lub luag haujlwm" piv rau "tus qauv" cov khoom lag luam. Nws yog ib qho teeb meem ntawm seb tus ncej ntoo khaub lig- ntu, ntawm qhov siab thiab ntu nws yuav ua haujlwm, muaj qhov nruj geometric kom deflection qis dua qhov pib ntawm tib neeg kev nkag siab.
Qhov thib peb sib txawv - thiab ib tug lub luag hauj lwm rau kwv yees li ib nrab ntawm tag nrho cov kev tsis txaus siab wobble uas manufacturers tau txais - nyob rau hauv qab lub lawj nto. Ib tug ncej tuaj yeem ua tsev ib qho khoom siv dav hlau txhuas hauv nws; Yog hais tias nws txoj kev sib txuas rau lub lawj cia siab rau ob lub undersized screws nyob rau hauv ib tug nyias puag phaj, tag nrho cov sib dhos yuav shimmy nyob rau hauv cua. Peb txoj hauv kev anchoring tshwm sim hauv kev xyaum, thiab lawv tsis hloov pauv tau:
| Txoj kev Anchoring | Thaum Nws Siv | Dab tsi ua rau nws ua haujlwm | Dab tsi ua rau nws poob |
|---|---|---|---|
| Cast-hauv- qhov chaw embedment | Tshiab qhob ncuav - ncej teem ncaj qha rau hauv ntub slab | Monolithic pob zeb-rau- ncej txuas; xoom mechanical pob qij txha kom loosen lub sijhawm | Tshaj tawm tsis braced plumb thaum lub sij hawm nchuav thiab kho - cov pob zeb ua thiab cov lean yog ruaj khov |
| Base phaj nrog expansion anchors | Cov pob zeb uas twb muaj lawm - phaj bolted rau kho slab | Plaub los yog ntau dua stainless anchorsntawm txoj kab uas hla txaus los ntawm lub phaj tuab txaus kom tsis txhob flex nyob rau hauv bolt torque | Ob- cov phaj thauj tog rau nkoj; zinc-plated fasteners; daim hlau nyias dua li lawv yuav tsum yog |
| Lub tes tsho- ntxig rau hauv qhov cored | Cov pob zeb uas twb muaj lawm uas pom lub hauv paus phaj tsis xav tau | Embedment qhov tob yam tsawg kawg nkausib -quarter mus rau ib -peb ntawm saum toj no- av ncej qhov siab | Qhov tob tob; cia siab rau cov nplaum ib leeg yam tsis muaj cov cuab yeej siv rau hauv cov pob zeb pob zeb |
Ib qho kev nthuav dav uas paub txog cov neeg teeb tsa kawm los tshawb xyuas tam sim: post verticality. Ib tug ncej leaning txawm me ntsis tawm plumb rewrites tag nrho railing los ua ke qhov kev ntxhov siab tis. Kev sib txuas tsim los rau kev thauj khoom ntsug symmetrical dheev nqa lub sijhawm torsional uas lawv tsis tau tsim kho rau. Lub wobble uas ua rau muaj kev cuam tshuam nrog txhua lub voj voog thermal raws li cov kev sib txuas uas nyuaj siab ua haujlwm- tawv thiab txhim kho kev ua si. Ib qib laser lossis qib siab siab ntev siv rau txhua tus ncej hauv ob lub dav hlau perpendicular, ua ntej cov railing seem yog mounted, raug nqi tsib feeb rau ib tug ncej thiab tiv thaiv ib tug zuj zus degradation uas tsis muaj tom qab zawm yuav thim rov qab.
Qhov thib plaub kuj sib txawv zaum nyob rau hauv cov connectors - cov brackets koom posts rau rails, lub ces kaum daim ntawm tes rov qab, lub iav clamps yog hais tias iav infill panels. Cov no yog cov khoom me me, pheej yig tshaj plaws hauv kev sib dhos railing, thiab lawv niaj hnub ua thawj zaug ua tsis tiav hauv txoj hauv kev uas tsim ob qho tib si wobble thiab suab nrov. Cov hlau txuas yuav tsum yog stainless hlau - hom nrog matte, sov nyiaj - dawb suab, tsis yog lub ci ntsa iab xiav - chrome cam khwb cia ntawm zinc- plated steel. Plastic connectors yuav tsum xav tias tuab-walled thiab burr-dawb, nrog rau kev txhawb nqa ribbing pom ntawm lub ntsej muag tom qab. Fastener torque tseem ceeb heev: lub hau ntswj tsav kom txog thaum nws strips nws cov xov nyob rau hauv PVC tus thawj coj los ua lub hauv paus ntsiab lus ntawm kev loj hlob loosening thoob plaws tag nrho cov kev sib txuas.
Wobble yuav luag tsis muaj ib qho - taw tes ua tsis tiav. Nws accumulates - ib tug me ntsis undersized post puag ua ke nrog anchors uas poob ib lub hlis twg - tig ntawm preload tshaj ob lub caij ntuj no, ua ke nrog ib tug connector bracket torqued rau "xav nruj txaus" es tsis yog ib tug specification. Txhua yam ib leeg yog NW nyuam qhuav pom. Ua ke, lawv tsim qhov tshee hnyo ib tus tswv tsev xav tias thaum lawv ntsoos tiv thaiv sab saum toj ntawm txoj kev tsheb ciav hlau thaum yav tsaus ntuj.Tib qhov kev qhuab qhia tshwj xeeb siv rau PVC fencing - peb xya- lub ntsiab lus xaiv lub ntsiab lus npog qhov sib piv.
III. Lub hnub yog ib qho tshuaj reactor. Koj Cov Xim Xim Xim nyob hauv nws.
Muaj ib qho kev poob siab tshwj xeeb uas cov tswv tsev piav qhia nrog cov lus yuav luag zoo ib yam thoob plaws huab cua thiab cov khoom lag luam: railing saib chav ua yeeb yam - zoo meej rau thawj xyoo, pib saib nkees los ntawm xyoo peb, thiab xyoo tsib tau ploj mus rau hauv chalky, patchy dab ntawm nws cov xim qub - thaum lub sij hawm tus tswv pib lub siab xav hloov. Qhov kev sib tw no muaj ntau heev nyob rau hauv qis - cov khoom siv PVC uas nws tau dhau los ua cov khoom siv rau pej xeem lub koob npe nrov, txawm tias qhov tseeb tias cov tshuaj tiv thaiv nws tau nkag siab zoo rau ntau xyoo lawm.
Dab tsi tshwm sim ntawm qib molecular yog qhov no: ultraviolet photons muaj lub zog txaus los rhuav tshem cov pa roj carbon -chlorine bonds hauv PVC polymer qaum. Lub dehydrochlorination cov tshuaj tiv thaiv uas ua raws li tso tawm hydrogen chloride, uas nyob rau hauv lem catalyzes ntxiv degradation nyob rau hauv tus kheej -accelerating cascade. Macroscopically, cov khoom yellows, chalks ntawm qhov chaw, thiab poob cuam tshuam lub zog. Kev txwv cov saw hlau no yuav tsum muaj peb yam tshuaj lom neeg ua haujlwm ua ntu zus. Ua ntej, rutile -qib titanium dioxide - loaded generously rau hauv formulation - ua raws li lub cev UV opacifier, xav txog thiab tawg photons ua ntej lawv mus txog lub polymer matrix. Qhov thib ob, cov organic UV absorbers ntes lub zog nyob rau hauv qhov tseem ceeb UV wavelength qhov rais thiab dissipate nws li tsis muaj teeb meem tsawg- qib cua sov. Thib peb, hindered amine teeb stabilizers - HALS hauv kev lag luam shorthand - scavenge cov dawb radicals uas UV raug generates, cuam tshuam lub degradation cascade ua ntej nws propagates los ntawm cov khoom. Tshem tawm ib qho ntawm peb qhov no, thiab lub moos pib zuam ntawm lub railing qhov tsos. Tshem tawm ob, thiab ticking yuav hnov nyob rau hauv ob lub caij ntuj sov.
Ib tus neeg yuav khoom uas xav paub tseeb tias cov khoom siv railing tau muab tso rau qhov no triple - tiv thaiv kab ke muaj ob txoj hauv kev. Thawj yog thov kom ceev huab cua ntsuas cov ntaub ntawv - tshwj xeeb, QUV lossis xenon- kuaj arc nrog xim- hloov pauv qhov tseem ceeb tshaj tawm ntawm ib txhiab teev ntawm qhov raug lossis ntau dua. Ib qho zoo- cov khoom tsim tawm yuav qhia cov xim drift hauv qab qhov pib ntawm kev xav ntawm tib neeg kev xav ntawm qhov ntsuas ntawd. Cov ntaub ntawv ntsuam xyuas uas hais txog kev lag luam- qauv qauv rau kev ntsuas xim yog qhov koj tab tom nrhiav. Txoj kev thib ob yog qhov yooj yim dua: nug seb cov chaw tsim khoom puas muab daim ntawv pov thawj ntawm kaum xyoo lossis ntev dua uas tshwj xeeb rau kev tuav xim. Ib lub tuam txhab uas koom nrog nws cov lus lees paub ntawm kev tiv thaiv kev ploj mus tau nrawm dua sab hauv - cov ntaub ntawv kev laus uas txhawb nqa qhov kev thov. Ib lub tuam txhab uas zam cov ntsiab lus hauv nws cov lus lav yog, los ntawm qhov tsis ua haujlwm, sib txuas lus cov kev txwv ntawm nws cov peev txheej tsim.
Kuj tseem muaj kev tsim tawm - txheej txheem. Premium vinyl railing siv co-extrusion - qhov kev lag luam hu ua capstock technology. Thaum lub sij hawm extrusion profile, ib tug thib ob extruder siv ib tug nyias txheej - ib feem ntawm ib millimeter - ntawm heev UV-concentrated, pigment- nplua nuj formulation rau ntawm profile nto thaum ob txheej tseem molten. Ob txheej txheej fuse molecularly rau hauv ib chav tsev inseparable. Lub capstock tsom ntsoov rau kev tiv thaiv UV kim raws nraim qhov nws xav tau - ntawm qhov chaw raug - es tsis yog muab nws pov tseg los ntawm tag nrho cov profile cross-section. Tus ntiv tes khawb hla qhov tsis pom kev sab nraub qaum qhia tias cov cuab yeej siv li cas hauv kev ua si: yog tias lub cim kos yog dawb tawm tsam xim xim, koj tab tom saib cov khoom capstock; Yog hais tias khawb phim lub cev xim, cov khoom siv los ntawm - lub cev pigmentation, uas ua lag luam tawm txawv ntawm khawb qhov tsis pom thiab ntev - lub sij hawm UV endurance.
Co-extrusion cross-section: txheej txheej txheej nyias nyias nqa lub siab UV- tiv thaiv chemistry, fused rau cov txheej txheem PVC core uas tswj cov khoom siv kho tshuab.
Qhov tseeb ntawm lub cev uas tsis muaj kev tsim tawm tuaj yeem cuam tshuam tag nrho: cov xim tsaus nti nqus ntau lub hnub ci infrared hluav taws xob ntau dua li lub teeb xim. Qhov kub thiab txias ntawm qhov tsaus ntuj - xim PVC railing nyob rau lub caij ntuj sov lub hnub tuaj yeem nce mus txog xya caum degrees Celsius - qhov kub thiab txias uas ua rau txhua txoj kev degradation ib txhij. Nyob rau hauv qhov kub, siab - thaj tsam hnub ci, xim yooj yim tshaj plaws thiab zoo tshaj plaws - tuav lub tswv yim yog xaiv cov xim dawb, cream, lub teeb grey, lossis xim beige txias. Yog hais tias ib qhov project tsim hom lus kiag li yuav tsum tau ib tug maub railing, peb qhov kev lees paub yog qhov tseem ceeb: cov khoom yuav tsum tau sau npe tias yog ib qho tsaus nti- xim formulations nrog ntxiv kub stabilizers thiab reflective pigments; txhua qhov kev thauj khoom-cov tswvcuab bearing yuav tsum suav nrog cov khoom siv aluminium, vim PVC poob qhov tawv nqaij thaum kub nce thiab tsaus nti profiles khiav kub dua; thiab cov chaw tsim khoom yuav tsum muab qhov tsaus ntuj -xim- cov lus qhia tshwj xeeb uas lees paub qhov chaw pabcuam xav tau ntau dua. Ib qho kev coj ua kom tsis txhob tag nrho: txau cov PVC railing dawb nrog cov xim tsaus tom qab kev teeb tsa. Cov xim pleev xim rau cov yam ntxwv tsis tau muab tso rau hauv PVC daim ntawv thermal nyiaj txiag, thiab thermal expansion mismatch ntawm cov xim zaj duab xis thiab PVC substrate yuav tsim tev thiab tawg nyob rau hauv ib mus rau ob lub caij.
Kev tsim kev sib haum xeeb uas ua rau qhov tsaus ntuj -PVC thermal kev sib tw: dawb PVC cov qauv ncej thiab sab saum toj rail rau siab tshaj plaws hnub ci reflectivity, ua ke nrog cov hmoov tsaus nti -coated aluminium balusters. Qhov zoo nkauj cuam tshuam ntawm qhov tsaus nti railing, tsis muaj kev nplua thermal rau ntawm PVC qauv.
IV. Rust tshwm sim. Txawm nyob rau hauv ib yam khoom Marketed li Rust-Cov pov thawj.
PVC lub cev ntawm lub railing tsis tuaj yeem xeb - cov saw hlau polymer tsis koom nrog electrochemical oxidation. Qhov kev puas tsuaj xeb nyob tag nrho hauv cov khoom siv hlau uas txuas, thauj tog rau nkoj, thiab txiav cov khoom sib dhos. Thiab nws yog qhov zoo tshaj plaws uas feem ntau ib qho dej tsis zoo -txoj kev tsheb ciav hlau raug coj los ntawm ib pawg ntawm cov khoom tsis raug cai.
Muaj kev kuaj pom uas siv tsib vib nas this ntawm cov khoom siv kho vajtse thiab ua rau tus tswv xyoo ntawm xeb -streak khuv xim. Muab lub taub hau stainless hlau nyob ib sab ntawm ib lub zinc-plated ntsia hlau rau ntawm daim ntawv dawb. Lub stainless fastener muaj ib tug matte, sov nyiaj - dawb suab - lub ntuj xim ntawm cov hlau. Lub zinc-plated fastener muaj lub ci ci, ci ntsa iab, xiav-chrome cam - kos npe ntawm electroplated zinc. Nyob rau hauv uas nyias zinc txheej zaum zoo tib yam carbon hlau. Thaum huab cua, ntsev, los yog ib qho kev khawb khawb ua txhaum lub plating, cov hlau xeb, thiab xeb - cov xim dej yuav ua rau cov PVC dawb lub ntsej muag, tso hlau - oxide stains uas tsis muaj cov neeg siv khoom- qib nqus tsev ntxhua khaub ncaws tshem tawm tag nrho.
Daim tshev no tsis raug nqi dab tsi. Nws yuav tsum tsis muaj cuab yeej. Thiab nws tiv thaiv ib qho uas feem ntau tshwm sim thiab pom kev ua phem ntev - lub sij hawm tsis ua hauj lwm hauv PVC railing sib dhos.
Rau cov chaw ntug dej hiav txwv - nyob qhov twg hauv ob peb mais ntawm kev sib tsoo nthwv dej - lossis thaj chaw uas lub caij ntuj no txoj kev ntsev aerosol mus txog lub lawj, cov khoom siv tshwj xeeb yuav tsum mus rau ib qib ntxiv. Cov khoom siv stainless hlau tiv thaiv atmospheric corrosion txaus nyob rau hauv dej, qis -chloride ib puag ncig. Cov qib marine hloov dua siab tshiab ntxiv molybdenum rau cov alloy - feem ntau yog ob mus rau peb feem pua - uas ua rau muaj kev txhim kho zoo rau cov tshuaj chloride- ion pitting uas ntsev tsuag thiab de- cov tshuaj icing induce. Tus nqi sib txawv ntawm ob qib no, siv rau tag nrho cov nqi fastener ntawm ib qho chaw nyob hauv railing, yog negligible. Qhov tshwm sim ntawm kev xaiv cov qib qis hauv ib puag ncig ntsev yog xeb streaks tshwm nyob rau hauv kaum yim hli.
Tshaj li fasteners, aluminium Cheebtsam - reinforcing cores uas txuas mus rau exposed xaus, puag daim hlau, connector brackets - xav tau lawv tus kheej corrosion xav. Cov txhuas tsis kho tsis tsim cov hlau xeb, tab sis nws ua oxidize rau hauv grey - cov hmoov dawb uas hloov mus rau tes thiab khaub ncaws ntawm kev sib cuag. Qhov tseeb specification yog anodized los yog hmoov-coated aluminium rau txhua qhov txhuas qhov chaw uas yuav tsum tau kov los yog lub ntsej muag sab nraud. Anodizing tsim cov txheej txheem oxide tswj rau hauv cov hlau nws tus kheej; hmoov txheej siv rau ci- ntawm cov yeeb yaj kiab polymer. Ob leeg ua haujlwm.
Ib qho tsis ncaj qha xeb cuam tshuam rau cov tswv tsev los ntawm kev xav tsis thoob: kev sib kis los ntawm cov tsev nyob ib sab. Yog hais tias ib tug neeg nyob ze lub rusting wrought - hlau balconies zaum saum koj PVC railing, los yog ib tug steel downpipe bracket overhead yog shedding corrosion hais, hlau -oxide- dej laden yuav drip mus rau PVC nto thiab deposit stubborn txiv kab ntxwv - xim av stains. Lub PVC nws tus kheej tseem tsis cuam tshuam - qhov no yog teeb meem tshuaj pleev ib ce, tsis yog cov khoom tsis ua haujlwm - tab sis cov stains yog tiag tiag thiab tawv ncauj. Kev tiv thaiv cuam tshuam nrog kev lees paub thaum lub sijhawm teeb tsa tias lub tes tuav saum toj kawg nkaus muaj lub qhov dej ntws los yog cov qhov dej hauv lub kaus mom uas tso dej sai sai thiab taw qhia, thiab cog lus rau cov xab npum txhua xyoo- thiab- dej ntxuav uas ua kom lub ntsej muag du txaus rau cov kab mob paug rau cov hlaws thiab yob tawm es tsis txhob kis thiab evaporate rau hauv qhov chaw.
V. Height Codes, Infill Choices, and the Shape of the Handrail - Tau Txais Kev Txiav Txim Siab Thib Ob
Tshaj li peb lub ntsiab lus tseem ceeb, ib qho kev txiav txim siab thib ob cais ib qho kev sib tw uas nyeem raws li kev sib koom ua ke ntawm cov khoom siv los ntawm ib qho uas nyeem raws li cov khoom lag luam bolted rau lub lawj.
Kev ua raws li qhov siab yog qhov tsis yog - qhov pib sib tham. Cov kab lis kev cai nyob hauv North American tau teeb tsa lub lawj thiab lub sam thiaj guardrail yam tsawg kawg nkaus ntawm peb caug- rau nti, nrog lub sam thiaj railings ntawm plaub caug-ob ntiv tes. Cov lej thoob ntiaj teb feem ntau xav tau txog ib 'meter' thiab tsib centimeters rau qis-nce thaj chaw thiab ib 'meter' thiab kaum centimeters rau siab -nce. Qhov yuav tsum tau ua nrog qhov siab yam tsawg kawg nkaus - thiab ib qho uas tau saib ntau zaus - yog qhov siab tshaj plaws - hla qhov qhib ntawm balusters, feem ntau yog plaub ntiv tes, tiv thaiv tus me nyuam lub taub hau los ntawm kev hla. Zoo PVC railing systems xa nrog code{12}}cov ntaub ntawv ua raws. Kev lees paub tias cov ntaub ntawv hais txog koj txoj cai tswjfwm cov cai tshwj xeeb yog ib kauj ruam tsim nyog ua ntej lub railing tawm hauv lub tsev rau khoom.
Infill xaiv - cov ntaub ntawv sau qhov chaw nruab nrab ntawm cov ncej thiab hauv qab txoj kab saum toj kawg nkaus - cuam tshuam rau ob qho tib si zoo nkauj thiab cua load. Vertical balusters ntawm plaub-inch qhov sib nrug yog qhov kev xaiv ntau tshaj plaws, thiab daim tshev ntawm no yog qhov yooj yim: paub meej tias cov phab ntsa baluster thickness sib phim cov qauv txheej txheem. Qee cov tuam txhab xa khoom nyias nyias- cov phab ntsa balusters tshaj cov ntawv tshaj tawm raws li tus nqi - txo kev ntsuas, thiab qhov txawv yog qhov tsis pom ib zaug ntsia tab sis muaj txiaj ntsig dhau sijhawm. Tempered iav panels xa cov duab tsis pom kev tab sis xav tau cov iav tshwj xeeb-clamp kho vajtse ntsuas rau cov iav tuab thiab cov cua hauv zos. PVC zoo nkauj lattice panels muaj kev ceev ntiag tug thiab cua tsis kam tab sis siv zog tseem ceeb ntawm lawv cov mounting brackets - lub bracket specification tsim nyog tau txais kev tshuaj xyuas ntau npaum li cov ncej anchors.
Handrail geometry yog qhov sib txawv ntawm ergonomic uas cov neeg yuav khoom feem ntau pom tsuas yog tom qab kev teeb tsa, thaum qhov profile tsis zoo tshaj tawm nws tus kheej los ntawm kev tsis xis nyob. Ib tug ntoo khaub lig- seem uas yog oval los yog generously radiused rectangular caw ib tug ntseeg tuav; ib tug ntse -edged tiaj tus duab plaub sau npe raws li tsis kaj siab nyob rau hauv ntev tes kov. Cov txheej txheem zoo tshaj plaws qhwv cov tub ntxhais aluminium nrog PVC lub plhaub sab nraud ntawm lub tes tuav - cov txhuas muab cov txheej txheem txuas ntxiv, PVC ua kom lub ntsej muag tsis txhob kub hnyiab thaum lub caij ntuj sov los yog mob khaub thuas thaum lub caij ntuj no Frost. Cov hlau tiag tiag thiab cov ntoo tsis muaj clad ob leeg tsis muaj qhov txiaj ntsig zoo.
Tom qab kev teeb tsa, kaum-feeb taug kev- los ntawm kev ntes cov teeb meem uas yuav tshaj tawm lawv tus kheej maj mam dhau thawj xyoo. Nias kom ruaj khov ntawm nruab nrab - ncua ntawm txoj kab saum toj kawg nkaus. Tuav txhua lub baluster thiab sim twist nws. Saib rau sab saum toj rail length. Xyuas kom tseeb tias tag nrho cov ncej caps, rail kawg caps, thiab trim npog tau zaum tag nrho tsis muaj qhov khoob uas tuaj yeem lees txais los nag. Xyuas kom pom tias txhua lub taub hau ntsia hlau pom dej ntws tawm nrog nws qhov chaw nyob ib puag ncig thiab tsis muaj qhov pom tias stripped - xov puas. Txhua yam khoom ntawm daim ntawv teev npe uas dhau mus tam sim no yog hu rau kev pabcuam uas yuav tsis tshwm sim tom qab.
VI. Dab tsi kaum tsib xyoos ntawm kev muaj tswv tiag nug koj
Ib qho kev qhia kom raug thiab raug teeb tsa PVC railing system nug yuav luag tsis muaj dab tsi nyob hauv nws lub neej kev pabcuam. Kev saib xyuas txhua xyoo haum rau hauv ib kab lus: ntxuav nrog xab npum me me thiab ib daim ntaub mos muag lossis daim txhuam cev, yaug nrog lub vaj hose. Tsis muaj xuab zeb. Tsis staining. Tsis muaj xeb-scraping. Tsis muaj xim. Thoob plaws kaum tsib xyoos, kev ua haujlwm sib txawv ntawm PVC thiab nws cov kev hloov ib txwm muaj - raug nqi ntawm ib teev twg tsim nyog tus nqi - tshaj tag nrho cov khoom siv ntawm PVC system. Ib tus tswv tsev uas yuav tau siv sijhawm ob hnub so hauv ib xyoos los tuav lub rooj ntoo yuav siv sijhawm li ib teev hauv ib xyoos los tuav PVC.
Rau cov ntaub so ntswg uas xab npum thiab dej tsis tshem tawm - cov noog poob uas tau ci rau, paj ntoos seem nyob rau hauv qhov chaw ntxoov ntxoo - ib qho tsis yog- cov ntaub pua tsev ntxhua khaub ncaws uas tsim los rau PVC cov khoom siv ua cov xab npum tawm tom qab. Dab tsi yuav tsum tsis txhob kov ntawm qhov chaw: muaj zog acidic cleaners, abrasive pads los yog steel wool, thiab siab washers nyob ze. Siab - dej siab tuaj yeem yuam kom cov dej noo dhau los ua cov ntsaws ruaj ruaj rau hauv cov ncej sab hauv, qhov twg cov kais dej nkag los ua qhov teeb meem ntev - lub sij hawm substrate. Yog hais tias ib tug railing seem txhawb nqa ib tug tob khawb los yog cuam tshuam gouge, me me nto cov cim yuav ntub dej -sanded nrog nplua - ntawv grit thiab kho nrog ib tug vinyl restoration compound. Ib qho kev puas tsuaj loj heev ntawm tus kheej - ib qho tawg ntho, lub tsho gouged ncej - tuaj yeem raug tshem tawm thiab hloov hauv kev sib cais yam tsis muaj kev cuam tshuam rau lwm lub rooj sib txoos. Qhov no modular repairability yog ib tug zoo structural zoo uas welded hlau thiab tsis tu ncua -khiav ntoo railing systems tsis muaj.YUPSENI stocks ib tug neeg hloov khoom rau txhua railing profile nyob rau hauv ntau lawm.
Thaum tag nrho - cov nqi voj voog tau kwv yees thoob plaws ib xyoo caum thiab ib nrab, ib qho kev qhia zoo PVC railing system feem ntau tshwm sim raws li tus nqi pheej yig tshaj rau tus kheej - tsis yog vim tias cov khoom nws tus kheej yog tus pheej yig tshaj los yuav, tab sis vim tias kev ua tswv cuab tsis tsim cov ntawv xa nyiaj rov qab. Ntoo railing yuav tsum tau re-staining txhua ob mus rau peb xyoos. Hlau yuav tsum tau repainting txhua peb mus rau tsib xyoos, ntxiv rau qee zaus weld kho thaum xeb pom cov pob qij txha. Ob qho khoom siv degrade los ntawm qhov chaw sab hauv; ob leeg yuam tus tswv mus rau hauv daim ntawv qhia hnub tu uas zoo li plam raws li lub xyoo sib sau. PVC railing, los ntawm qhov sib txawv, nug rau xab npum, dej, thiab kwv yees li ib teev ntawm kev ua haujlwm hauv ib xyoos. Lub cev polymer tsis tuaj yeem rot lossis xeb. Cov co-extruded capstock ua kom xim hloov qis dua qhov pib ntawm kev nkag siab zoo ib yam li kaum xyoo lossis ntau dua. Cov khoom siv stainless hlau txuas ntxiv ua dab tsi stainless ua. Kev saib xyuas qhov sib txawv yog categorical, tsis incremental.
