Vim muaj cov noob polar nyob rau hauv cov qauv macromolecular ntawm chlorinated polyethylene (CPE) thiab cov qauv xoob ntawm nws cov hmoov, tsis yog tsuas yog "dej tsis khi" tab sis kuj "dej khi" hauv nws cov hmoov ntub, ua rau nws nyuaj rau ziab nws kom cov dej noo tsis pub ntau tshaj 0.3% (ntub).
Feem ntau 135A khaws cia rau hauv kev tsim khoom txhua hnub hauv cov tuam txhab lag luam, tab sis muaj cov kev cai rau txoj kev khaws cia ntawm CPE135A. Kev khaws cia tsis zoo tuaj yeem ua rau muaj kev hloov pauv ntawm cov yam ntxwv ntawm CPE135a, uas tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom rau qee qhov. Ib qho yog tsis txhob khaws cia CPE135a ntev, nws tuaj yeem ua tau raws li qhov xav tau txhua hnub, vim tias peb lub peev xwm muab khoom txaus los ua kom tau raws li koj cov xaj txhua lub sijhawm. Yog tias lub tuam txhab yuav tsum khaws cia qee qhov ntawm CPE135a, nws yuav tsum tau them sai sai rau txoj kev khaws cia. Hauv qab no yog peb lub ntsiab lus uas yuav tsum nco ntsoov thaum khaws cia.
Ua ntej, nws yog ib qho tsim nyog los ua haujlwm zoo ntawm kev kaw. Yog tias CPE135A raug rau huab cua ntev, nws yooj yim rau kev ua haujlwm thiab hloov nws cov khoom siv tshuaj lom neeg, ua rau muaj kev hloov pauv hauv nws cov kev ua tau zoo. Cov neeg siv yuav tsum tsis txhob kov CPE135A thiab huab cua.
Qhov thib ob, nws yog ib qho tsim nyog los ua haujlwm zoo hauv kev ua haujlwm tiv thaiv dej noo. Rau txhua yam khoom, kev raug cua noo ntev ntev tuaj yeem ua rau puas tsuaj, tsis txhob hais txog cpe135A. Cov neeg siv khoom yuav tsum ua haujlwm zoo hauv kev ua haujlwm tiv thaiv dej noo.
Qhov thib peb, nws yog ib qho tsim nyog kom tsis txhob muaj qhov kub siab hauv qhov chaw ua haujlwm ntawm CPE135A. Thaum khaws cia CPE135A, nws yog ib qho tseem ceeb kom tswj tau qhov kub ntawm ib puag ncig, vim tias qhov kub siab dhau tuaj yeem ua rau muaj kev tsis haum rau CPE135A. Yog li ntawd, cov neeg siv khoom yuav tsum ua haujlwm zoo hauv kev tswj qhov kub.
Vim yog cov chlorine ntau ntawm CPVC resin, nws qhov kev tiv thaiv kev cuam tshuam tsis zoo dua li PVC resin, thiab nws yuav tsum tau hloov kho los ntawm kev ntxiv cov khoom hloov pauv. Cov khoom hloov pauv feem ntau suav nrog CPE, MBS, ABS, thiab ACR. Ntxiv CPE thaum lub sijhawm ua cov kav dej CPVC muaj qhov cuam tshuam loj heev, nrog rau qhov cuam tshuam zoo tshaj plaws tshwm sim ntawm 8-12 qhov. Txawm li cas los xij, ntxiv CPE yuav txo qhov kub ntawm Vicat softening ntawm cov kav dej; MBS thiab ABS muaj qhov cuam tshuam me ntsis rau qhov kub ntawm Vicat softening, tab sis vim muaj cov unsaturated ob chav bonds hauv lawv cov saw molecular, lawv qhov kev tiv thaiv huab cua tsis zoo; Impact resistant ACR yog qhov hloov pauv zoo tagnrho, tab sis nws tus nqi siab heev.
