Koj puas paub PVC qab nthab?

Koj puas paub dab tsi kho mob infusion raj yog ua los ntawm? Koj puas paub tias koj tab tom taug kev hauv tsev kho mob? Koj puas paub dab tsi yog pw hauv pem teb tsheb npav? Tom qab ntawd peb yuav tsum hais txog PVC, thiab PVC flooring.

PVC flooring yog ib yam tshiab uas nrov heev ntawm lub teeb yuag pem teb npog cov ntaub ntawv nyob rau hauv lub ntiaj teb no niaj hnub no, kuj hu ua "lub teeb yuag flooring". Cov khoom siv tseem ceeb rau kev tsim cov flooring PVC yog polyvinyl chloride, uas yog ib puag ncig tus phooj ywg, tsis yog - tshuaj lom, thiab siv tau dua tshiab. Nws tau ntev tau siv dav hauv lub neej niaj hnub, xws li hauv cov tais diav, kev kho mob infusion raj thiab hnab, yog li nws cov phooj ywg ib puag ncig yog dhau qhov tsis ntseeg. Txawm li cas los xij, rau PVC flooring yuav tsum tsis yog tiag tiag - tshuaj lom thiab ib puag ncig tus phooj ywg, cov yas siv yog qhov tseem ceeb. PVC nws tus kheej yog cov khoom siv nruj; ntxiv plasticizers ua rau nws mos, yooj yim rau khoov, quav, thiab elastic, yooj yim shaping.

1.Raw Material Batching thiab Pretreatment

Cov khoom siv tseem ceeb: Polyvinyl chloride (PVC) resin hmoov (50% -70% los ntawm qhov hnyav), siv txoj kev ncua kev kawm lossis txoj kev emulsion resin nyob ntawm cov khoom lag luam.

Cov ntaub ntawv pab: Plasticizers (DOP / epoxidized soybean roj los txhim kho kev yooj yim), stabilizers, calcium carbonate muab tub lim (kom txo nqi thiab nce hardness), nplaim hluav taws (txhuas hydroxide), pigments (xim hmoov lossis masterbatch).

Pretreatment: Raw cov ntaub ntawv yog sieved thiab qhuav (humidity Tsawg dua los yog sib npaug rau 0.3%) thiab ces precisely hnyav raws li cov mis nyuj los xyuas kom meej batch sib xws.

2.Siab -Speed ​​Mixing and Plasticization

Kev sib xyaw: Cov khoom siv raw yog muab tso rau hauv lub siab- sib tov ceev (ceev ntau dua lossis sib npaug li 1000 r / min), thiab qhov kub tau nce mus rau 100-120 degree, tso cai rau PVC resin thiab plasticizers kom yaj tag nrho thiab tsim ib qho kev muab tshuaj txhuam.

Plasticization: Cov sib tov yog pauv mus rau ib qho khoom siv sab hauv lossis ntxaib- ntsia hlau extruder, qhov uas nws ntxiv plasticized ntawm 150-180℃kom tshem tawm npuas thiab txhim kho cov khoom ntom ntom.

Txheej txheem txheej txheem

 

 

01.

Calendering (Yob)

Multi- txheej txheej: Cov khoom siv PVC yas hla dhau los ntawm ntau- yob calenders (yob kub 160-190 degree) kom ua raws li txheej txheej (ua npuas dej), txheej luam ntawv, thiab hnav txheej (pob tshab PVC + aluminium oxide).

Kev kho cov txheej txheem ua npuas ncauj: Lub hauv paus txheej tau nthuav dav hauv lub tshuab ua npuas dej (200{1}}220 degree) los tsim cov qauv elastic kaw nrog qhov ntom ntawm 0.6-0.9 g / cm³.

02.

Extrusion (cov ntawv)

Co-extrusion: Siv ntau- txheej co-extrusion tuag, txheej hnav, txheej luam tawm, thiab txheej txheej tseem ceeb (siab- ntom PVC + fiberglass mesh reinforcement) yog extruded ib txhij, ces txias los ntawm sizing rollers thiab txiav rau hauv paus boards.

3. Kev kho deg

UV txheej: UV- txheej txheej kho tau (thickness 0.2-}0.5 mm) yog siv rau txheej hnav los ntawm cov ntaub thaiv npog lossis cov menyuam txheej txhawm rau txhim kho khawb tsis kam (txog T-qib hnav tsis kam).

Embossing: Hlau cov menyuam embossing los yog laser engraving yog siv los xyaum ntoo grain, pob zeb, thiab lwm yam peb -dimensional textures, nyob rau tib lub sij hawm txhim kho plam tsis kam (ntub xeev R9 qib).

Ncej -Kev Ua Haujlwm thiab Kev Tshuaj Xyuas Zoo

Kev laus / Kev ntxhov siab: Cov khoom tiav lawm tau tso rau hauv qhov chaw ua haujlwm kub thiab av noo tas li rau 48 teev kom tso tawm cov kev ntxhov siab sab hauv thiab tiv thaiv deformation.

Kev soj ntsuam zoo: Cov kev ntsuam xyuas muaj xws li kev puas tsuaj (Taber txoj kev), tensile lub zog ntawm lub kaw lus kaw (Ntau dua lossis sib npaug ntawm 1500 N / m), qhov ntsuas hluav taws kub (cone calorimeter test rau qib B1), thiab lwm yam. Cov khoom tsim nyog tau ntim thiab khaws cia.

1.PVC ceilings muaj ntau hom qauv thiab xaiv ntau yam xim thiab cov qauv, muab ntau txoj kev xaiv rau cov neeg siv khoom xaiv.

2.PVC ceilings ua tau zoo nyob rau hauv ntau yam, xws li lub teeb yuag, yooj yim rau nruab, waterproof, thiab soundproof. Txij li feem ntau PVC qab nthab niaj hnub no yog ua los ntawm cov nplaim taws- cov ntaub ntawv retardant, lawv kuj muab hluav taws kub zoo, ua rau lawv muaj kev nyab xeeb dua.

3.Vim lawv cov nqi tsim khoom qis, PVC qab nthab yog pheej yig dua li lwm hom qab nthab, ua rau lawv tsim nyog rau tsev neeg zoo tib yam.

Hauv cov teb chaws tsim, PVC flooring tau hloov pauv cov vuas luaj ceramic thiab ntoo flooring. Ua ke nrog lawv cov kev paub txog ib puag ncig thiab kev txhawj xeeb txog kev noj qab haus huv ntawm tus kheej, PVC flooring tau dhau los ua kev lag luam loj hauv cov teb chaws tsim. Nws yog qhov nyiam hauv pem teb npog rau cov chaw pej xeem nrog kev nyab xeeb siab, xws li tshav dav hlau, tsev kho mob, kindergartens, thiab tsev kawm ntawv. Cov khaubncaws sab nraud povtseg ntawm PVC flooring muaj cov khoom tshwj xeeb resistant; piv rau cov ntaub ntawv hauv pem teb zoo tib yam, PVC flooring xav tias muaj kev tuav ntau dua thaum ntub, ua rau nws tsis tshua muaj kev cuam tshuam. Nyob rau hauv ib puag ncig uas yuav tsum tau nyob ntsiag to, xws li tsev kho mob pawg ntseeg, tsev kawm ntawv cov tsev qiv ntawv, chav hais lus, thiab xinesmas, PVC flooring muab lub suab rwb thaiv tsev zoo uas cov khoom siv hauv pem teb zoo ib yam tsis tuaj yeem sib xws - tsis muaj suab nrov thaum lub siab heels taug kev. Tsis tas li ntawd, PVC flooring muaj cov tshuaj tua kab mob, ib yam dab tsi uas xyoob thiab cov khoom ntoo hauv pem teb tsis tuaj yeem ua tiav.
