Cov kev xav tau rau cov xim pleev xim rau hauv kev tsim cov PVC ua npuas ncauj

1. Dab tsi yuav tsum tau them sai sai rau thaum tsim cov xim pleev xim ntawm PVC ua npuas ncauj board?

Qhov saum npoo ntawm PVC ua npuas ncauj yog du thiab tawv, thiab nws tsis yooj yim los tsim khawb.Piv txwv li, cov txheej txheem tha xim ntawm PVC txee thiab PVC chav dej txee.Yog li dab tsi yog qhov yuav tsum tau ua rau cov xim pleev xim thaum tsim cov PVC ua npuas ncauj?Lub tshuab engraving tuaj yeem ua raws li tus qauv tsim, thiab tom qab ntawd xaiv qhov chaw nrog Millenian slate lossis txheej;Txawm li cas los xij, xyuam xim rau lub hollow foam board.Yog tias qhov saum npoo tsis du, nws tuaj yeem tsuas yog lub tshuab nqus tsev overmolded.Cov khoom siv yuav tsum yog 2 hli tuab polyvinyl chloride board.Kev khoov tsuas yog tsim rau cov khoom ua npuas ncauj, tsis yog rau hollow ua npuas ncauj boards.Cov txheej txheem ua haujlwm yog siv cov pwm sab saud thiab qis dua los npog qhov chaw ntawm cov ntoo pwm nrog cov ntawv txhuas, thiab tom qab ntawd ua kom sov cov khoom ua npuas ncauj rau 70 ° C thiab plasticizing kub rau 90 ° C.Extrude ncaj qha los ntawm cov pwm sab saud thiab qis.Hauv extrusion ntau lawm ntawm tus kheej nplaum PVC, ntoo nplej nrog cov qauv sib txawv tuaj yeem luam tawm ntawm qhov chaw raws li qhov xav tau, tshem tawm cov txheej txheem tsis tsim nyog.

PVC ua npuas ncauj board tuaj yeem coated.Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua cov kua roj vanish zoo tib yam, piano ci kua roj vanish thiab ceramic ci varnish.Anti-ultraviolet cov khoom xyaw yog ntxiv rau lub piano ci kua roj vanish kom tsis txhob nto decoloration;Nyob rau hauv cov nqe lus ntawm deg hardness, ceramic ci varnish muaj qhov zoo ntawm khawb kuj.PVC ua npuas ncauj board yog nrov heev thiab nrhiav tom qab nyob rau hauv lub khw muag khoom zoo nkauj.Ntau tus neeg siv yuav xaiv nws rau kev kho kom zoo nkauj hauv tsev thiab nce kev zoo nkauj.Tab sis ceev faj cov phooj ywg yuav pom tias qee cov PVC ua npuas ncauj yuav muaj npuas rau ntawm qhov chaw tom qab siv mus ntev, uas cuam tshuam rau lawv txoj kev zoo nkauj.

Yog li dab tsi yog vim li cas rau cov npuas hauv PVC ua npuas ncauj?

Cov txheej yog txau tom qab lub zog nplawm, uas yuav ua rau lub ntsej muag ntawm PVC ua npuas ncauj tseem ua npuas dej, yog li nws yuav tsum tau tso rau 10-15 feeb kom txog thaum cov npuas ploj ua ntej txau.Tom qab ntawd muaj kev ua tsis tiav ntawm lub substrate, uas txhais tau hais tias lub substrate yuav tsum tau kaw tag, thiab lub substrate yuav tsum polished thiab du, tsis muaj grooves los yog pinholes.Tom qab ntawd, qhov chaw muaj cov dej noo ntau, cov av noo siab dhau lawm, thiab qhov kub ntawm qhov kub thiab txias yog siab dhau.Thaum qhov no tshwm sim, qhov chaw ntawm PVC ua npuas ncauj board tuaj yeem ua kom qhuav kom tsis txhob muaj kev tsim kho hauv qhov kub thiab txias ib puag ncig.Thaum kawg, cov viscosity siab dhau lawm, cov kuab tshuaj muaj dej, lossis cov cua compressed muaj dej los yog roj paug.Hauv qhov no, koj tuaj yeem siv cov tshuaj hnyav thiab dilute proportionally, los yog siv cov roj-dej cais los lim cov cua compressed thiab yuav tsum tau ua kom tsis tu ncua.

2. Puas yuav PVC ua npuas ncauj board deform nyob rau hauv lub hnub?

Lub softening kub ntawm PVC ua npuas ncauj board yog hais txog 75-80 ° C.Yog tias tawm sab nraum zoov, nws yuav ncav cuag qhov kub thiab txias, yog li nws yuav deform.

Yog vim li cas rau qhov deformation ntawm PVC ua npuas ncauj board: nws yog deformed vim kub thaum lub sij hawm ntau lawm txheej txheem.

Kev daws: Lub hom phiaj kev hloov kho ntawm cov khoom siv hluav taws xob kub-resistant yas tuaj yeem txhim kho cov teeb meem zoo li no.

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

Kev daws: Rov faib cov qauv raw khoom kom tau raws li qhov xav tau tiag tiag ntawm cov khoom.

Kev ua tsis raug thiab kev khaws cia tuaj yeem ua rau deformation.Cov teeb meem zoo li no tuaj yeem daws tau los ntawm lub hauv paus.
