Ib daim ntawv nyo hau tsis yog cov khoom uas ua tsis tiav. Nws yog ib yam khoom uas tuav kev ntxhov siab, thiab nres.
Ntawm nplooj ntawv no
- Warping yog cov tsos mob, tsis yog qhov tsis xws luag
- Qhov sib npaug ntawm ob lub ntsej muag
- Thermal Movement yog qhov qub. Kev txwv yog qhov teeb meem.
- Ib Lub Thawv hauv Lub Hnub
- Cia thiab qeeb qeeb Tsis muaj leej twg tus cwj pwm
- Thaum txiav tawm dab tsi yog khov rau hauv
- Diagnosing ib daim ntawv Warped
Daim ntawv warped yog ib qho ntawm ob peb qhov kev tsis txaus siab uas tuaj txog nrog cov ntaub ntawv pov thawj txuas nrog, thiab ib qho ntawm ob peb qhov kev pom tseeb yog qhov tsis ncaj ncees lawm. Lub instinct yog liam cov khoom. Cov khoom siv tsis tshua muaj vim li cas.
PVC tsis muaj cov cuab yeej hu ua flatness uas tuaj yeem teev thiab xa mus tsis tau. Qhov nws muaj yog qhov tawv nqaij, kev nthuav dav coefficient, thiab cov ntaub ntawv ntawm txhua yam uas tshwm sim rau nws ntawm qhov tuag thiab lub sijhawm koj saib nws. Distortion yog cov ntaub ntawv uas tau nyeem nrov nrov.
Cov qauv uas ua rau qhov no ua tau yog ib qho uas tau piav qhia hauv peb daim ntawmdaim tawv nqaij thiab tub ntxhais hauv PVC ua npuas ncauj board, thiab nws yog qhov chaw zoo pib.
I. Warping yog ib qho tsos mob, tsis muaj qhov tsis xws luag
Ib daim ntawv uas hneev yog ib daim ntawv uas muaj kev ntxhov siab tau pom.
Kev ntxhov siab nkag mus rau hauv daim ntawv PVC los ntawm ntau qhov kev qhia. Cov kab extrusion tso qee qhov los ntawm qhov tsis sib xws. Cia muab ib co nyob rau hauv los ntawm unsupported hnyav. Ib lub thawv nyob rau hauv lub hnub tso ib co hauv tshav kub. Kev teeb tsa tso qee qhov los ntawm kev tuav daim ntawv tseem thaum nws sim txav. Txiav muab qee qhov tso rau hauv los ntawm kev tshem tawm cov khoom uas ntsuas qhov seem.
Txhua tus ntawm cov no tsim cov txiaj ntsig zoo ib yam, uas yog vim li cas qhov kev kuaj mob feem ntau tsis yog lawm. Ib daim ntawv uas tuaj txog bowed thiab ib daim ntawv uas tau hneev peb lub hlis tom qab kev teeb tsa tuaj yeem saib zoo ib yam hauv daim duab thiab muaj lub hauv paus sib txawv kiag li.
Lo lus nug ua ntej
Tsis yog "yog cov khoom phem no", tab sis "thaum twg nws txav mus". Lub sij hawm nqaim qhov ua rau sai dua li kev soj ntsuam ntawm daim ntawv nws tus kheej.
Ib qho kev qhia meej tsim nyog ua ntej, vim tias lub npe caw qhov kev nyeem tsis raug. Hais tias cov resin tsis tshua muaj lub luag haujlwm tsis yog kev tiv thaiv ntawm cov chaw tsim khoom. Feem ntau ntawm cov ua rau hauv kab lus no zaum ntawm cov kab ntau lawm los yog hauv cov saw hlau, thiab ob qho tib si ntawm cov no yog leej twg ua thiab txav daim ntawv. Lub ntsiab lus yog tias qhov txhaum yuav luag tsis muaj nyob rau hauv cov tshuaj polymer, thiab saib qhov ntawd pov tseg qhov kev tshawb nrhiav.
II. Qhov sib npaug ntawm ob lub ntsej muag
Lub rooj tsavxwm ua npuas ncauj yog tsim los ua symmetrical. Ob daim tawv nqaij, ib qho tseem ceeb. Thaum ob daim tawv nqaij sib phim, cov quab yuam hauv ntu tshem tawm thiab daim ntawv zaum ncaj.
Thaum lawv tsis sib xws, daim ntawv khoov. Lub mechanism yog tib yam uas ua rau ib tug bimetallic strip curl nyob rau hauv ib tug thermostat.
Cov tub ntxhais yog nthuav tau ntau dua li cov tawv nqaij, vim tias cov khoom foamed muaj kev ywj pheej ntau dua li cov khoom siv. Ntawm cov cua sov, cov tub ntxhais xav kom loj hlob ntau tshaj qhov chaw nyob ib ncig ntawm nws. Ib daim tawv nqaij tawv tuav nws rov qab. Yog tias ib lub ntsej muag nqa cov tawv nqaij hnyav dua li lwm tus, ib sab yog tuav rov qab ntau dua li lwm tus, thiab daim ntawv daws qhov sib txawv los ntawm kev khoov.
Cov tawv nqaij sib npaug
Kev sib npaug ntawm ob lub ntsej muag. Ntu kev daws teeb meem sab hauv thiab daim ntawv nyob twj ywm los ntawm kev hloov pauv kub, yog tias nws tuaj yeem txav mus los ntawm cov npoo.
Cov tawv nqaij tsis sib npaug
Ib lub ntsej muag txwv ntau dua li lwm tus. Daim ntawv nyo hau rau ntawm daim tawv nqaij hnyav dua, thiab nws yuav ua kom ntseeg tau txaus tias qhov kev taw qhia ntawm hneev taw qhia koj lub ntsej muag twg yog denser.
Cov ntsiab lus kawg no yeej muaj txiaj ntsig zoo hauv kev tsis sib haum xeeb. Ib tug hneev taw uas ib txwm daws rau tib lub ntsej muag, hla ntau nplooj ntawv los ntawm tib lub pallet, cov ntsiab lus ntawm qhov tsis sib xws tsim ntawm kab. Tsis sib xws, lub calibrator khiav sov ntawm ib sab, ib tug tuag khiav me ntsis tawm ntawm qhov chaw, los yog tsis sib xws thauj - tawm nro yuav tag nrho nws.
Qhov no yog ib qho ua rau hauv kab lus uas yog unambiguously tus neeg tsim khoom kho. Cov seem yog sib koom ntawm cov khoom siv sib txuas thiab qhov chaw nruab.
III. Thermal Movement yog qhov qub. Kev txwv yog qhov teeb meem.
PVC txav thaum nws sov. Qhov no tsis yog qhov txhaum, thiab qhov luaj li cas ntawm lub zog yog kwv yees los ntawm ib daim duab uas twb zaum ntawm daim ntawv teev cov ntaub ntawv.
Lub coefficient ntawm linear thermal expansion rau nruj PVC khiav ntawm kwv yees li 0.07 millimeters ib meter ib℃Celsius. Siv rau daim ntawv txheem 2440 millimeter, nees nkaum℃viav vias txav txhua ntug txog peb millimeters. Peb caug degrees txav nws ncig tsib. Plaub caug degrees tau ze rau xya.
Ib daim ntawv txheem txav ob peb millimeters ib hnub twg
Ib lub vaj huam sib luag uas ntsia lub hnub tuaj yeem viav peb caug degrees lossis ntau dua thaum sawv ntxov thiab nruab nrab - tav su. Tshaj li 2440 millimeter ncua uas yog kwv yees li tsib millimeters ntawm kev txav mus los, rov qab mus rau qhov chaw uas nws pib los ntawm tag kis sawv ntxov. Nws tsis yog kev puas tsuaj. Nws yog cov khoom siv ua haujlwm.
Distortion tshwm sim thaum lub zog ntawd tiv thaiv. Kho ib daim ntawv nruj ntawm tag nrho plaub ntug thiab tsib millimeters tsis muaj qhov twg mus. Lub expansion hloov mus rau hauv compression nyob rau hauv lub dav hlau ntawm daim ntawv, thiab ib tug ca vaj huam sib luag nyob rau hauv - dav hlau compression buckles tawm ntawm lub dav hlau. Qhov tshwm sim yog nthwv dej uas tshwm sim tsis muaj leej twg tuaj yeem pom.
Uas muab cov npe luv luv ntawm kev teeb tsa tus cwj pwm uas ua rau feem ntau ntawm kev ua tsov rog.
Fixings nruj ntawm txhua ntug, tawm hauv tsis muaj ntug txav mus los. Kev txwv yuav tsum nyob ntawm ib ntug lossis ib ncig ntawm qhov chaw nruab nrab, nrog rau qhov seem tso cai rau swb.
Plain round qhov es tsis yog slotted los yog oversized sawv daws yuav. Ib qho kev kho uas tsis tuaj yeem swb hloov lub vaj huam sib luag mus rau hauv ib qho kev txwv.
Tshaj -tightened screws, uas tsim kom muaj kev ntxhov siab hauv zos thiab tsim ib lub pob nyob ib ncig ntawm txhua qhov kho es tsis yog ib lub hneev.
Tsis muaj qhov sib txawv perimeter qhov twg daim ntawv ua tau raws li tus ncej, uas tshem tawm qhov chaw uas lub vaj huam sib luag xav tau ntawm nws qhov sov tshaj plaws.
Txhim kho rau lub substrate uas nthuav dav ntawm tus nqi sib txawv, uas yuam cov ntawv ua raws li lwm yam kev txav mus los tsis yog nws tus kheej.
Tib lub hauv paus ntsiab lus pom nyob thoob plaws qhov seem ntawm cov khoom lag luam. Peb kev tawg ntawmPVC thermal expansion hauv trim, laj kab thiab qab nthabnpog yuav ua li cas cov physics zoo tib yam tsim cracking, sagging thiab gapping nyob rau hauv lwm yam profiles.
IV. Ib Lub Thawv hauv Lub Hnub
Qhov no yog qhov ua rau muaj kev sib cav ntau tshaj plaws, vim tias qhov kev puas tsuaj tshwm sim ua ntej leej twg yuav ua tus tswv ntawm cov khoom.
Lub thawv steel sawv hauv lub hnub ncaj qha rau ntawm qhov chaw nres nkoj lossis lub tsheb ciav hlau ua kom sov zoo tshaj qhov ambient. Sab hauv ntawm lub thawv kaw nyob rau hauv cov xwm txheej no tuaj yeem kub ntau dua li huab cua sab nraud, thiab qhov cuam tshuam loj dua rau cov nplooj ntawv ze tshaj plaws ntawm lub hnub-tawm phab ntsa thiab sab saum toj ntawm pawg.
Daim duab cuam tshuam los ntawm cov ntaub ntawv yog cov cua sov deflection kub, uas rau peb cov qauv ua npuas ncauj qib zaum ntawm 55 degrees Celsius. Qhov ntawd yog lub ntsiab lus ntawm cov khoom siv softens txaus rau deform nyob rau hauv load es tsis txhob tiv nws. Thawv sab hauv tuaj yeem mus txog qhov ntau ntawm hnub kub.
Yog vim li cas ib pawg tuaj yeem tuaj yeem hneev thiab tom qab ntawd nyob twj ywm
Softened khoom nyob rau hauv ib tug sustained load creeps. Qhov hnyav ntawm pawg saum toj no yog raws nraim li cov khoom thauj, thiab nws ua haujlwm rau lub lis piam. Tsis zoo li thermal txav, creep tsis thim rov qab thaum daim ntawv txias. Lub distortion yog teem los ntawm lub sij hawm lub thawv qhib.
Cov tswv yim mitigations yog tag nrho ntawm kev ntim khoom thiab routing sab. Txhawb cov pawg sib npaug thoob plaws tag nrho pallet es tsis yog qhov kawg nkaus ib leeg, nruab nrab ntawm pawg qhov siab kom cov nplooj ntawv qis dua tsis nqa cov khoom tsis tsim nyog, thiab xav txog qhov twg lub pallet zaum hauv lub thawv txheeb ze rau lub hnub - cov phab ntsa nthuav tawm ntawm txoj kev ntev.
Txoj kev cov nplooj ntawv tau ntim rau txoj kev taug kev muaj qhov cuam tshuam ncaj qha rau qhov lawv tuaj txog, thiab peb daim raupacking cov ntaub ntawv hauv tsev rau kev xa khoomnpog cov kev txiav txim siab dav dua.
V. Cia thiab qeeb qeeb Tsis muaj leej twg tus cwj pwm
Cov nplooj ntawv uas tiaj tus thaum tuaj txog tuaj yeem hneev rau hauv lub tsev khaws khoom, thiab cov txheej txheem qeeb txaus uas tsis muaj leej twg txuas rau ob qhov xwm txheej.
| Yuav khaws cia li cas | Yuav ua li cas |
|---|---|
| Pav ca, siab txhawb, theem nto | ruaj khov. Qhov no yog qhov kev npaj nkaus xwb uas ua rau tsis muaj kev cuam tshuam. |
| Pav ca, tab sis nyob rau hauv pem teb tsis sib xws | Daim ntawv siv ib txheej txuam nrog hauv pem teb, maj mam thiab mus tas li |
| Txhawb thaum kawg nkaus xwb | Sags nyob rau hauv nruab nrab nyob rau hauv nws tus kheej qhov hnyav tshaj lub lis piam |
| Leaning ntawm ntug tiv thaiv phab ntsa | Hneev raws qhov ntev, thiab cov ntawv qis tshaj nyo hau feem ntau |
| Nyob ze ntawm lub rhaub lossis glazing | Ib lub ntsej muag sov dua li lwm qhov, uas ua rau hneev nti ntau dua li sag |
| Sab nraum zoov nyob rau hauv lub hnub ncaj qha | Daim ntawv saum toj kawg nkaus heats ntau tshaj li cov pawg hauv qab no, yog li ob peb nplooj ntawv distort thiab tus so tsis ua |
Cov kab kawg no yog tus uas ntes neeg tawm. Ib qho kev xa khoom uas peb daim ntawv tawm ntawm plaub caug raug nyo thiab qhov seem yog qhov zoo yog qhov kev kos npe, tsis yog ib qho kev tsim khoom, thiab nws feem ntau taw qhia txog yuav ua li cas lub pallet tau tso tseg tom qab tshem tawm ntau dua li qhov uas tau tshwm sim ua ntej.
Lub sijhawm yog lwm qhov sib txawv. Ib daim ntawv khaws cia tsis zoo rau ib lub lim tiam feem ntau yuav rov zoo dua thaum pw tiaj tus. Ib daim ntawv khaws cia tsis zoo rau ib xyoos tau siv cov txheej txheem uas cov cua sov yuav tsis tshem tawm tag nrho, vim tias qhov deformation tsis yog elastic lawm.
Muaj kev cuam tshuam cuam tshuam tsim nyog paub txog hauv txoj kevQhov ntom ntom cuam tshuam rau qhov tawv. Qhov qis dua - daim ntawv ntom ntom nqa tsawg dua ua ntej nws deforms, yog li tib qhov chaw cia khoom uas tsis muaj teeb meem rau lub rooj tsav xwm ntom ntom yuav teeb lub teeb.
VI. Thaum txiav tawm dab tsi yog khov rau hauv
Extrusion tawm kev ntxhov siab kaw rau hauv cov khoom, sib npaug tawm thoob plaws qhov dav ntawm daim ntawv. Tshem tawm ib feem ntawm daim ntawv tshem tawm ib feem ntawm qhov sib npaug.
Thawj lub cim ntawm qhov no yog qhov offcut. Txiav ib txoj hlua ntev ntawm ntug ntawm ib daim ntawv loj thiab saib nws. Yog tias nws nkhaus tam sim ntawd, daim ntawv tau nqa kev ntxhov siab thiab txiav tawm nws. Qhov no yog ib txwm mus rau ib qho kev kawm, thiab nws dhau los ua teeb meem thaum qhov ua tiav tsis yog qhov chaw txaus rau nws txoj haujlwm.
Qhov loj version yog los ntawm routing. Txiav ib qho zawj lossis ib qho nyiaj rov qab rau hauv ib lub ntsej muag tshem tawm cov tawv nqaij ntawm sab ntawd, thiab cov seem uas sib npaug yuav tsis sib npaug. Ib lub vaj huam sib luag uas zaum zoo kawg nkaus ua ntej machining tuaj yeem hneev taw ib zaug ib txoj hlua zoo nkauj hla nws, thiab tus hneev yuav nyob nruab nrab ntawm thaj chaw machined.
Ob tus cwj pwm txo nws. Tshuab ob lub ntsej muag uas tus tsim tso cai, yog li cov seem nyob twj ywm symmetrical. Thiab cia machined qhov chaw zaum rau ib lub sij hawm ua ntej zaum kawg kho, vim hais tias ib co ntawm lub zog tshwm sim nyob rau hauv lub sij hawm tom qab txiav es instantly.
VII. Diagnosing ib daim ntawv Warped
Ob lo lus nug daws feem ntau. Thaum twg qhov distortion tshwm sim, thiab nws zoo li cas.
Thaum nws tshwm sim
Bowed rau cov ntsiab lus tuaj txog ntawm kev thauj mus los thiab ntim khoom kub. Hnov tom qab lub lis piam nyob rau hauv koj tus kheej cov ntsiab lus warehouse ntawm cia. Bowed tom qab kev teeb tsa cov ntsiab lus ntawm kev txwv lossis thermal txav. Bowed tom qab machining cov ntsiab lus ntawm kev ntxhov siab tso tawm.
Lub sijhawm kuaj mob ntau dua li qhov ntsuas ntawm daim ntawv.
Seb nws thim rov qab
Muab daim ntawv tiaj tus rau hauv qhov chaw txias, theem thiab tawm mus. Distortion uas yooj yim yog thermal thiab elastic, ua los ntawm qhov kub thiab txias gradient hla ntu. Distortion uas tseem tshuav yog ib txheej, xws li los ntawm creep los yog los ntawm kev ntxhov siab tso tawm, thiab nws yuav tsis tawm.
Qhov kev sim no tsuas yog cais cov neeg mob rov qab los ntawm tus so.
| Cov duab ntawm qhov distortion | Feem ntau yuav yog keeb kwm |
|---|---|
| Txawm hneev raws qhov ntev, ob qho tib si xaus ua ke | Cia los yog kev thauj mus los stacking nyob rau hauv sustained load |
| Cupping hla qhov dav | Cov tawv nqaij tsis sib xws, los ntawm cov kab extrusion |
| Twist los yog kauv | Kev tuav, lossis tsis sib npaug ntawm cov kab |
| Bowing nyob rau hauv ib qho chaw machined | Cov khoom raug tshem tawm ntawm ib lub ntsej muag |
| Local bulges nyob ib ncig ntawm tus kheej fixings | Tshaj -tightened fixings or restrained expansion at the point |
| Rippled los yog wavy npoo | Thermal expansion ntawm ntug uas tsis tau tso tseg |
| Tsuas yog qee cov ntawv hauv ib pawg cuam tshuam | Ib -ib sab cua kub raug thaum lub sij hawm cia |
Qhov twg qhov kev kuaj mob tsaws ntawm txoj kab extrusion nws tus kheej, cov ntaub ntawv pov thawj muaj txiaj ntsig yog kev sib piv rau kev xa khoom dhau los es tsis yog ib qho kev ntsuas. Hneev uas tsis tu ncua nyiam ib lub ntsej muag, hla ob peb nplooj ntawv los ntawm tib qhov kev ua haujlwm, yog qhov kos npe uas taw qhia ntawm qhov txias lossis ntsuas qhov sib npaug. Cov tshev hauv pebteb xyuas cov ntsiab lus siv dua tshiabua raws tib lub tswv yim ntawm kev nyeem ib daim ntawv tawm tsam nws tus kheej keeb kwm.
Thiab qhov twg qhov kev kuaj mob tsaws ntawm kev tsim, uas qee zaus nws ua, tus neeg raug liam yuav luag tsis muaj qib resin nws tus kheej. It is a very low density that leaves the sheet too flexible to resist creep, or a filler loading high enough to change how the section behaves thermally. Ob qho tib si yog kev txiav txim siab sau tseg hauv qhov sib xyaw, thiab ob qho tib si pom hauv cov tshev hauv peb phau ntawv qhiaDab tsi yog qhov tseeb hauv daim ntawv PVC.
Qhov luv version
PVC daim ntawv warps thaum muaj kev ntxhov siab pom, thiab qhov kev ntxhov siab yuav luag ib txwm los ntawm qhov tsis sib xws ntawm qhov cua txias ntawm txoj kab, tshav kub thaum lub sij hawm thauj mus los, tsis muaj kev txhawb nqa, kev txwv tsis pub thermal txav, lossis cov khoom tshem tawm los ntawm machining. Qib resin tsis tshua muaj qhov ua rau. Tsim kom muaj qhov sib txawv ntawm qhov tshwm sim, sim seb nws thim rov qab thaum nteg tiaj tus, phim cov duab tawm tsam lub rooj, thiab kho qhov laj thawj tsis yog hloov daim ntawv.
Cov lus nug nquag
PVC Sheet Warping Cov lus nug
Cov lus nug nquag los ntawm installers, fabricators thiab importers.
Puas yog daim ntawv warped PVC puas tuaj yeem rov ua dua?
Qee zaum. Muab nws tso rau ntawm ib qho chaw nyob hauv qhov chaw txias thiab tawm mus. Distortion ua los ntawm qhov kub thiab txias gradient hla ntu yog elastic thiab yuav yooj yim raws li daim ntawv sib npaug. Distortion uas los ntawm creep nyob rau hauv load, los yog los ntawm kev ntxhov siab tso tawm los ntawm kev txiav, tau dhau los ua ib tug mus tas li teeb thiab yuav tsis tawm. Lub tiaj-ntev kev sim qhia koj tias koj muaj qhov twg.
Yuav ua li cas npaum li cas yog ib tug PVC daim ntawv yeej txav nrog kub?
Rigid PVC nthuav dav ntawm kwv yees li 0.07 millimeters ib meter ib℃Celsius. Ntawm daim ntawv txheem 2440 millimeter, nees nkaum℃viav vias txav txhua ntug txog peb millimeters thiab plaub caug℃viav vias nws ze rau xya. Qhov kev txav ntawd yog qhov qub thiab tsis muaj teeb meem yog tias daim ntawv dawb ua rau nws. Distortion tshwm sim thaum lub zog tiv thaiv.
Vim li cas kuv cov ntawv tuaj txog nyo ntawm tus neeg muag khoom?
Qhov feem ntau yuav ua rau yog cua sov thaum caij tsheb thauj mus los ua ke nrog kev thauj mus los. Lub thawv steel nyob rau hauv lub hnub ncaj qha tuaj yeem ncav cuag qhov kub ntawm cov khoom kub deflection, ntawm qhov taw tes ntawm pawg hnyav saum ib daim ntawv ua rau nws nkag mus. Creep tsis thim rov qab rau qhov txias. Kev txhawb nqa pallet tsis sib xws thiab ntau ntau pawg qhov siab ob qho tib si ua rau nws tsis zoo, yog li cov txheej txheem ntim khoom tseem ceeb npaum li txoj kev.
Yuav khaws cov ntawv PVC li cas?
Pav ca, nyob rau theem saum npoo, muaj kev txhawb nqa thoob plaws tag nrho cov ntawv ntau dua li ntawm qhov kawg, tawm ntawm lub hnub ncaj qha thiab deb ntawm qhov chaw tshav kub, nrog cov pawg qhov siab khaws cia nruab nrab. Lwm qhov kev npaj yuav hloov cov nplooj ntawv raws sijhawm. Xaus-kev txhawb nqa cia ua ib qho sag, khaws cia rau ntawm phab ntsa ntawm ntug tsim ib hneev, thiab ib sab - cua sov ua rau nkhaus es tsis yog.
Vim li cas kuv lub vaj huam sib luag hneev tom qab kuv tau hla ib qhov zawj rau hauv nws?
Vim tias seem tau sib npaug ua ntej koj tshem tawm cov khoom ntawm nws. Lub rooj tsavxwm ua npuas ncauj muaj cov tawv nqaij tawv ntawm ob lub ntsej muag, thiab txiav rau hauv ib lub ntsej muag hloov qhov kev txwv ntawm sab ntawd. Daim ntawv daws qhov tsis sib xws los ntawm kev khoov, thiab hneev taw zoo nkaus li nyob nruab nrab ntawm thaj chaw machined. Machining ob lub ntsej muag nyob qhov twg tus qauv tso cai khaws cov seem symmetrical thiab txo cov nyhuv.
Kuv puas xav tau qhov sib txawv ntawm PVC ntawv?
Yog, nyob qhov twg lub vaj huam sib luag yog txwv los ntawm ib tug ncej, ib tug channel los yog ib tug ruaj perimeter. Ib daim ntawv txheem txav ob peb millimeters nruab nrab ntawm lub caij txias thaum sawv ntxov thiab yav tav su sov, thiab lub zog ntawd yuav tsum mus rau qhov chaw. Tsis muaj qhov sib txawv nws hloov mus rau hauv compression hauv lub vaj huam sib luag thiab pom zoo li buckling. Kev kho yuav tsum tau tso cai rau zawv zawg, siv cov slotted los yog loj qhov ntau es tsis yog nruj nreem.
Cov formulation puas tuaj yeem ua rau warping?
Qee zaus, tab sis tsis tshua muaj los ntawm cov resin nws tus kheej. Qhov ntom ntom qis txaus kom tawm ntawm daim ntawv hloov pauv dhau lawm yuav ua rau nws yooj yim rau nkag mus rau hauv kev thauj khoom, thiab cov khoom hnyav hnyav hloov pauv li cas ntu coj mus rau thermally. Ob leeg yog vim li cas tiag. Lawv kuj tsis tshua muaj ntau dua li kev ua haujlwm tsis txaus, kev thauj mus los, kev cia khoom tsis zoo thiab kev teeb tsa, uas yog vim li cas qhov kev tshawb nrhiav yuav tsum pib muaj.
Taug qab qhov teeb meem Distortion
Xa peb cov duab ntawm qhov distortion, thaum nws tshwm sim thiab yuav ua li cas cov nplooj ntawv khaws cia, thiab peb yuav nqaim qhov ua rau thiab paub meej tias dab tsi tom ntej batch yuav tsum hloov.
