Cov kav dej thiab cov khoom siv CPVC tau dhau los ua qhov kev xaiv zoo tshaj plaws hauv kev lag luam, kev lag luam, thiab kev siv hauv tsev vim lawv qhov kev ua tau zoo tshaj plaws, kev ruaj khov, thiab kev hloov pauv tau yooj yim. Raws li kev hloov kho PVC, CPVC cov kav dej thiab cov khoom siv muaj cov yam ntxwv zoo dua li cov khoom siv kav dej ib txwm muaj.
Cov kav dej thiab cov khoom siv CPVC muaj peev xwm tiv taus kub heev, zoo tagnrho rau cov tshuab dej kub. Ib qho cim tseem ceeb ntawm lawv qhov kev tiv taus kub yog lawv qhov kub Vicat softening temperature (VST) siab, feem ntau yog li ntawm 90 ℃ txog 110 ℃, uas qhia txog lub peev xwm ntawm cov khoom siv los khaws nws cov duab hauv qab cua sov.
Lawv cov tshuaj tiv thaiv zoo heev tiv thaiv cov kua qaub, alkalis, ntsev, thiab cov organic solvents, tiv thaiv kev puas tsuaj thiab xau. Tsis tas li ntawd, CPVC yeeb nkab thiab cov khoom siv muaj peev xwm ua tau siab dua, tsim qauv sib dua rau kev teeb tsa yooj yim, ua kom muaj cua sov tsawg rau kev siv hluav taws xob, thiab tsis muaj tshuaj lom, tsis muaj txhuas, ua kom muaj kev nyab xeeb thiab kev sib haum xeeb rau ib puag ncig.
Cov yam ntxwv no ua rau CPVC yeeb nkab thiab cov khoom siv sib txawv heev. Hauv tsev, lawv siv dav rau cov kav dej kub thiab txias, cov kav dej tso pa tawm, thiab cov kab ke ncig pas dej ua ke, tiv taus chlorine kom ntseeg tau ntev. Kev lag luam, CPVC yeeb nkab thiab cov khoom siv pab cov kav dej hauv chaw ua haujlwm, tsev so, thiab khw loj, HVAC condensate thiab cov kav dej txias, thiab cov tshuab tua hluav taws pheej yig hauv cov tsev qis. Hauv kev lag luam, lawv yog qhov tseem ceeb rau kev thauj cov kua dej corrosive hauv cov chaw tsim tshuaj lom neeg, cov kav dej tiv taus tshuaj lom neeg hauv cov chaw kho dej, cov kav dej kub hauv cov chaw tsim hluav taws xob, thiab kev tswj cov kua dej kom zoo hauv kev tsim khoom noj, tshuaj, thiab khoom siv hluav taws xob. Cov tsev kawm ntawv thiab tsev kho mob kuj vam khom lawv rau dej haus thiab cov kav dej uas tsis tas yuav saib xyuas ntau.

| Ca-Zn | Hmoov | TP-9931 | S-PVC | CPVC yeeb nkab thiab fitting, txhim kho Vicat, zoo heev kub stability thiab zoo heev fluidity |
Hmoov calcium zinc stabilizersNws muaj kev ruaj khov zoo heev, uas ua rau qhov kub ntawm CPVC cov khoom Vicat softening nce siab, thaum muab cov kua dej zoo heev thiab ua tau zoo heev. Lawv nqus cov hydrochloric acid uas tso tawm thaum lub sijhawm CPVC dehydrochlorination los tiv thaiv kev puas tsuaj, brittleness thiab discoloration. Lub caij no, nws tuaj yeem hloov ib feem ntawm Methyl Tin stabilizers thaum txo cov nqi tsim khoom tag nrho.
Cov tshuaj stabilizer Ca Zn tsis muaj txhuas kiag li, tsis muaj hlau hnyav, thiab tsis muaj tshuaj lom, ua kom cov yeeb nkab CPVC thiab cov khoom siv tsis ua rau ib puag ncig puas tsuaj. Nws tiv thaiv kev xau thaum lub sijhawm tsim khoom, siv, lossis pov tseg, ua rau lawv tsim nyog rau cov tsev ntsuab. Los ntawm kev khaws cia cov khoom tseem ceeb ntawm CPVC yeeb nkab thiab cov khoom siv yam tsis muaj kev cuam tshuam rau ib puag ncig, nws ua rau lawv muaj nqis ntau dua li kev daws teeb meem kav dej ruaj khov rau txhua qhov kev siv.
