Yuav tsum muaj rau cov xim saum npoo av hauv kev tsim cov tshuab pvc ua npuas

1. Dab tsi yuav tsum tau them nyiaj rau thaum tsim cov xim saum npoo ntawm PVC ua npuas board?

Qhov saum npoo ntawm pvc ua npuas board yog du thiab nyuaj, thiab nws tsis yooj yim los ua cov khawb. Piv txwv li, cov txheej txheem tha xim duab ntawm PVC cov tub ceev thiab PVC chav dej. Yog li dab tsi yog qhov yuav tsum tau ua rau cov xim nto thaum ua PVC ua npuas ncauj? Lub tshuab kos duab tau ua tau zoo li yog tsim raws kev kos duab, thiab tom qab ntawd xaiv cov nplaim zeb nrog cov millenian slate lossis txheej; Txawm li cas los xij, them sai sai rau cov hollow npuas board. Yog tias qhov saum npoo tsis du, nws tsuas tuaj yeem ua tau lub tshuab nqus tsev. Cov khoom yuav tsum yog 2 hli tuab polyvinyl chloride board. Dabtsi yog khoov tsuas yog tsim nyog rau cov laug cam ua npuas ncauj, tsis yog rau hollow npuas camam laug cam. Txoj kev ua yog siv cov pwm sab saud thiab qis dua cov hlau ntoo, thiab tom qab ntawd kub cov khoom ua npuas dej rau 70 ° C thiab qhov ziab txias rau 90 ° C. Extrude ncaj qha los ntawm cov pwm sab saud thiab qis dua. Nyob rau hauv kev extrusion kev tsim khoom ntawm tus kheej-nplaum PVC, Ntoo nplej nrog cov qauv sib txawv tuaj yeem luam tawm ntawm sab saum toj uas xav tau, tshem tawm cov txheej txheem kev ua haujlwm tsis tsim nyog.

PVC Ua npuas ncauj Board tuaj yeem muab cov coated. Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua cov kua roj varnish, Piano baking kua roj sternish thiab ceramic ci varsamp. Anti-ultraviolet cov khoom xyaw ntxiv yog ntxiv rau lub piano baking varnish kom tsis txhob muaj qhov chaw sib txawv; Hais txog saum npoo hardness, ceramic ci varsge muaj qhov zoo ntawm kev khawb tiv thaiv. PVC Ua npuas ncauj Board yog nrov heev thiab nrhiav tom qab hauv cov khoom siv zoo nkauj ua lag luam. Ntau tus neeg siv yuav xaiv nws rau kev kho kom zoo nkauj thiab nce kev zoo nkauj. Tab sis ceev faj cov phooj ywg yuav pom tias qee lub tsev ua npuas npuas dej yuav muaj cov npuas ntawm qhov chaw tom qab siv ntev, uas cuam tshuam rau lawv kev zoo nkauj.

Yog li dab tsi yog vim li cas rau cov npuas no hauv pvc ua npuas board?

Cov txheej tau txau tom qab siv lub zog ua kom zoo nkauj, uas yuav ua rau lub npoo ntawm pvc ua npuas dej tseem ua npuas dej tseem yog tso rau 10-15 feeb kom txog thaum lub npuas ploj ua ntej txau. Tom qab ntawd muaj cov txheej txheem tsis tiav ntawm cov txheej txheem tsis tiav ntawm cov substrate, uas txhais tau hais tias lub substrate yuav tsum tau kaw tag, thiab substrate yuav tsum tau polished thiab du, tsis muaj grooves lossis pinholes. Tom qab ntawd, cov nplaim muaj ntau ntawm noo noo, cov av noo yog siab dhau, thiab qhov chaw kub thiab kub siab dhau. Thaum qhov no tshwm sim, qhov saum npoo ntawm pvc ua npuas board tuaj yeem ua kom huv si kom tsis txhob muaj kev tsim kho hauv qhov kub thiab txias ib puag ncig. Thaum kawg, lub viscosity yog siab dhau, cov kuab tshuaj muaj dej, lossis cov cua compressed muaj dej lossis roj paug. Hauv qhov no, koj tuaj yeem siv cov kuab tshuaj kho mob thiab tshuaj lom neeg, lossis siv cov roj-dej separator los lim cov cua compressed thiab yuav tsum tau siv cov kua dej tas li.

2. Puas yog pvc foam board deform nyob rau hauv lub hnub?

Qhov muag muag kub ntawm PVC feam board yog kwv yees li 75-80 ° C. Yog tias kis tau sab nraum zoov, nws zoo li yuav ncav cuag qhov kub no, yog li nws yuav deform.

Qhov laj thawj rau deformation ntawm pvc ua npuas board: nws yog deformed vim qhov kub kub thaum lub sijhawm ntau lawm thaum lub sijhawm ntau lawm thaum lub sijhawm ua haujlwm ntau lawm.

Kev daws: Kev hloov kho lub hom phiaj ntawm cov khoom kub-resistant yas raw cov ntaub ntawv tuaj yeem txhim kho cov teeb meem no.

Muaj ob qho laj thawj rau kev deformation tshwm sim los ntawm kev tsim khoom tsis raug. Ib qho yog tias cov khoom siv lub cev ntawm cov khoom siv ntawm cov phaj tsis tuaj yeem ntsib qhov kev xav tau tiag tiag ntawm cov khoom.

Kev daws: Retistrible tus raw cov khoom siv kom tau raws li qhov kev thov tiag tiag ntawm cov khoom.

Kev ua haujlwm tsis raug thiab cov hau kev cia khoom tuaj yeem ua rau muaj kev deformation. Cov teeb meem no tuaj yeem daws tau los ntawm lub hauv paus cag.
