Thaum PVC ua npuas ncauj profiles tau qhia hauv xyoo 1970, lawv tau hu ua "ntoo ntawm lub neej yav tom ntej," thiab lawv cov tshuaj muaj pes tsawg leeg yog polyvinyl chloride.Vim tias kev siv dav dav ntawm PVC tsis tshua muaj foaming khoom, nws tuaj yeem hloov yuav luag txhua yam khoom siv ntoo.
Nyob rau hauv xyoo tas los no, thev naus laus zis ntawm PVC ua npuas ncauj profile tuam ntxhab kuj tau nce siab sai, tso cai rau cov khoom siv PVC ua npuas ncauj ua kom muaj kev lag luam hauv cov khoom siv vaj tsev thiab cov khoom siv zoo nkauj, nrog rau cov khoom tsim rau rooj tog.
Los ntawm kev ntxiv cov khoom sib txawv rau cov khoom siv PVC ua npuas ncauj, cov yam ntxwv sib txawv tau muab rau cov khoom siv PVC ua npuas ncauj.Nws nce qhov kev thov ntawm cov khoom nyob rau hauv lwm txoj kev siv ntau yam ntaub ntawv tsim kho thiab cov ntaub ntawv zoo nkauj tsim.Nyob rau tib lub sij hawm nyuaj PVC ua npuas ncauj khoom muaj zoo nto zoo nkauj zog.
Cov ntaub ntawv pov thawj noo noo, tiv thaiv corrosion, nplaim hluav taws kub, tsis muaj tshuaj lom, thiab tsw ntxhiab PVC ua npuas ncauj profile cov khoom no tuaj yeem txhim kho qhov chaw nyob, thiab cov txheej txheem PVC ua npuas ncauj yog tam sim no feem ntau yog siv cov PVC tsis muaj npuas thiab ua npuas ncauj. board, nrog rau lwm yam PVC ua npuas ncauj cov khoom zoo nkauj profiles, los tsim ib tug scale ntawm cov khoom siv technology.Daim ntawv thov kev tshawb fawb tau dhau los ua ntau yam hauv kev tsim kho, ntim khoom, rooj tog zaum, thiab lwm qhov chaw.
Qhov saum npoo ntawm PVC ua npuas dej tuaj yeem raug txau, uas tuaj yeem zam qhov kev hloov ntawm cov xim saum npoo thiab muaj qhov zoo ntawm kev tiv thaiv khawb nto hardness.Tom qab ntawd muaj peb txoj kev ua ntau lawm, nyob rau hauv qhov chaw muab tshuaj txhuam rau ntawm lub phaj siv lead ua, kev ua haujlwm feem ntau yuav tsis siv neeg mus rau ntug sealing tshuab, thiab tsis siv neeg ntug sealing tshuab yuav cuam tshuam rau kev faib ua cov menyuam hom qauv nrog rau crawler hom ob, tab sis yog tias tsis siv. siv lub hollow ua npuas ncauj thaum nws pom zoo kom siv thiab cov khoom muab tshuaj txhuam nto muaj cov xim zoo sib xws, tsis txhob muab cov ntawv muab tshuaj txhuam rau ntawm txoj kev loj hlob ntawm qhov shrinkage thaum qhia cov qauv tsim muaj xim sib txawv.
