Kev tsim cov khoom siv ua vaj tsev vov tsev vov PVC kom tau raws li qhov xav tau ntawm kev txhim kho kev lag luam. Cov khoom lag luam tsim los ntawm cov khoom siv ua tiav ru tsev PVC vov tsev yog cov ntaub ntawv tsim tsev tshiab tsim los ntawm kev ua haujlwm siab thiab tshiab thev naus laus zis. Lawv yog lub cim tshiab ntawm lub teeb pom kev tiv thaiv ib puag ncig lub tsev cov ntaub ntawv tawm dag zog thiab txhawb nqa los ntawm lub xeev. Cov khoom yog ib puag ncig ib puag ncig, lub zog-txuag thiab ua dua tshiab. Qhov tshwj xeeb ua tau zoo ntawm PVC cov khoom siv vov tsev cov vov tsev tau yeej cov neeg nyiam thiab paub txog kev tsim kho kev lag luam. Nws yog dav siv nyob rau hauv Kev Tshawb Fawb Thaj Av tiaj tus mus rau nqes hav, kev ua lag luam ua liaj ua teb, khw hauv khw, thaj chaw thaj chaw, thaj chaw siab, muaj tsev viav vias, tshav ntuj, khoom vaj tsev qub, thiab lwm yam. piv txwv li ib hom hluavtaws polymer. Raws li qhov kev ua ntawm sab nraud quab yuam, nws tuaj yeem nyob rau hauv lub xeev ntawm cov yas ntws, thiab qee tus yam ntxwv zoo ib yam li cov khoom siv ntawm ntuj tsim. Cov khoom saum npoo ntawm cov nplais hluavtaws tawv yog qhov tseem ceeb tshaj plaws. Kev xaiv ntawm cov khoom siv saum npoo cuam tshuam ncaj qha rau kev pab lub neej ntawm cob pobzeb. Feem ntau, cov khoom siv tiv thaiv huab cua zoo tshaj plaws ASA tau xaiv thiab thaum kawg tsim los ntawm cov npoo coextrusion. Weatherability ntawm cov khoom ncaj qha ua rau kev pab cuam lub neej ntawm cov nplais hluavtaws cov nplais hluav taws xob. Nyob rau tib lub sijhawm, cov khoom zoo ntawm cov khoom tsim los ntawm PVC vov tsev cov khoom siv pobzeb tseem muaj feem xyuam nrog kev siv cov khoom siv saum npoo av thiab coextrusion thev naus laus zis. Cov txuj ci hluavtaws cob pobzeb tuaj yeem tiv taus cov kua qaub, alkali, ntsev thiab lwm yam tshuaj lom neeg mus ntev. Cov xim siv hauv kev tsis zoo PVC ru tsev pobzeb saum npoo yuav ua rau tshuaj lom neeg cov tshuaj tiv thaiv thiab txawm ploj.
Cov khoom lag luam tsim los ntawm PVC cov vuas vov tsev cov cuab yeej tsim nyog rau pob zeb ua qauv, cov qauv ntoo, ntoo qauv, cib ntoo sib xyaw ntoo qauv thiab lwm yam qauv. PVC ru tsev cov khoom lag luam cov khoom lag luam tsim cov khoom tso tawm kom pom thaum kawg, txawm hais tias pib lig, tab sis nws cov zoo tau pom tseeb heev.
Ntuj tiv thaiv kev ua haujlwm, txawm hais tias cov pobzeb nws tus kheej raug rau cov xeb muaj zog tiv thaiv ib puag ncig xws li kua qaub, alkali thiab ntsev rau lub sijhawm ntev, nws kev ua haujlwm yuav tsis poob. Yog li no, cov khoom lag luam tsim los ntawm PVC cov vuas vov tsev cov khoom siv yog qhov tshwj xeeb tshaj yog rau cov chaw ntug hiav txwv thiab cov ru tsev ntawm cov nroj tsuag tshuaj lom neeg nrog kev xeb. Huab cua tiv taus zoo heev. Txawm hais tias nyob rau hauv kev cuam tshuam ntawm lub hnub ntev ntev, kev hloov pauv kub, cua thiab nag, hauv cov kev tshwm sim ntawm kev laus xws li fading, tshem tawm, tawg thiab txo lub zog yuav tsis tshwm. Haum cov kev lag luam peb txheej txheej txheej txheej txheej txheej tshuab, saum npoo ntawm cov khoom lag luam tsim los ntawm PVC vov tsev cov vov tsev cov cuab yeej siv kev ua haujlwm siab ultra-siab huab cua ua kom zoo nkauj engineering cob. Ntxiv nrog rau kev ntseeg tau cov xim ntawm cov khoom saum npoo yog zoo nkauj thiab kav ntev, nws kuj muaj qhov zoo ntawm cov khoom zoo thiab cuam tshuam. Cov txheej nruab nrab yog ua los ntawm cov qib high-PVC zoo, ntxiv los ntawm lub ntiaj teb' s ua cov khoom lag luam saum toj kawg nkaus, thiab hauv qab txheej yog cov huab cua tiv cob-resistant txheej. Cov khoom lag luam tsim los ntawm PVC ru tsev cov khoom siv vuas vov saws cov txheej txheem siab tshaj plaws peb txheej txheej txheej ua haujlwm hauv kev lag luam thiab txhua tus txais yuav cov ntaub ntawv zoo tshaj plaws kom ntseeg tau cov kev pab cuam super ntev lub neej ntawm cov khoom. Raws li Kev Tshawb Fawb ntawm Chaw Tshuaj Hauv Tebchaws, tsis muaj qhov sib nrug, tsis muaj kev txhawb nqa, thaum qhov hluav taws kub tawm sab nraud cov pa taws tam sim ntawd. Lub thermal conductivity ntawm steel yog ib feem peb ntawm cov hlau thiab ib kaum ob ntawm cov ntawm cov pob zeb ua, thiab nws cov kev ua haujlwm thermal rwb thaiv tsev yog qhov ua tau zoo dua lwm cov nplais.
