Chlorinated polyvinyl chloride (CPVC) yog cov khoom siv polymer tau tom qab ntxiv chlorination ntawm PVC.Lub cev thiab tshuaj lom neeg cov khoom hloov pauv loj: nrog rau cov ntsiab lus chlorine nce, qhov tsis sib xws ntawm cov saw hlau molecular nce thiab crystallinity txo;lub polarity ntawm molecular saw nce, lub zog intermolecular nce, thermal deformation kub nce ho, thiab cov khoom siv kho kom zoo.
CPVC yog qhov zoo dua li PVC hauv huab cua tsis kam, kev laus ua haujlwm thiab nplaim hluav taws.Piv txwv li, tom qab chlorination, qhov txwv oxygen Performance index ntawm PVC yuav nce los ntawm 45 ~ 49 mus rau> 70 (muaj 67% CPVC chlorine), thiab cov pa luam yeeb thiab cov pa roj carbon seem hauv cov nplaim taws yuav txo qis.Cov txheej txheem chlorination cuam tshuam cov khoom ntawm cov khoom.Cov ntsiab lus chlorine ntawm PVC tuaj yeem ncav cuag 73% tom qab chlorination.
Feem ntau los ntawm cov txheej txheem dej ncua sij hawm, tom qab sib tov PVC resin, los ntawm chlorination, pom, ntxuav, CPVC ntau lawm neutralization, ziab txheej txheem tiav, qhov zoo ntawm PVC hmoov cov khoom ntoo xaiv yog qhov tseem ceeb heev, tshwj xeeb tshaj yog cuam tshuam rau machining stability, thermal stability) , kev xaiv ntawm PVC resin raw khoom xoob, tawv li nyias li ua tau, cov qauv ntawm cov qib zoo zoo.Cov ntsiab lus chlorine dav dav yog 63% ~ 67%.Nws cov huab cua tsis kam, corrosion kuj, kev laus ua hauj lwm thiab nplaim retardant spontaneous combustion yog deb zoo tshaj li zoo tib yam PVC cob.Cov ntsiab lus chlorine nce, yog li vica softening point kub nce siab, 35 ℃ siab dua PVC resin, siab tshaj kub resistant kub mus txog 130 ℃, haum rau cov kav dej kub thiab fittings thiab daim hlau (xws li cov kav dej kub, pob qij txha, kub resistant. Cov khoom siv tshuaj lom neeg thiab lub tank cia).
UPVC yog PVC tawv.Ib qho khoom siv hloov kho yog npaj los ntawm kev ntxiv qee qhov kev hloov kho ntxiv raws li PVC ntoo hmoov."U" yog Unplasticized (Unplasticized), yog li qhov sib txawv tseem ceeb ntawm UPVC thiab PVC thiab mos PVC yog tias tsis muaj plasticizer ntxiv, calcium hmoov ntau dua, muaj zog txhua yam ntawm cov khoom, tsim nyog rau kev tsim cov li qub thiab cov kav dej.
CPVC yog chlorinated polyvinyl chloride.Raws li PVC resin, CPVC nce cov ntsiab lus chlorine hauv cov khoom siv PVC los ntawm qee cov txheej txheem, feem ntau yog li ntawm 63 txog 69%, txhawm rau txhim kho cov cua sov, acid, alkali, ntsev thiab oxidant corrosion ntawm cov khoom, thiab txhim kho thermal. deformation kub thiab mechanical zog ntawm cov khoom.
CPVC nce cov ntsiab lus chlorine ntawm PVC resin los ntawm kev siv tshuaj, yog li cov khoom siv ntawm CPVC resin yog siab.Nyob rau theem tom ntej, qee cov ntaub ntawv hloov kho yuav tsum tau siv rau cov khoom txhaj tshuaj lossis extrusion, uas ua rau tus nqi siab ntawm CPVC cov ntaub ntawv hloov kho.Tus nqi muag ntawm CPVC hloov cov khoom hauv Suav teb feem ntau yog siab dua 20,000 / tuj.
Vim tias tus nqi siab ntawm CPVC, nws tsis tuaj yeem siv rau cov khoom siv no kom dav li UPVC.Tam sim no, CPVC feem ntau yog siv hauv cov kav dej tua hluav taws, cov kav dej tshuaj tiv thaiv corrosion thiab cov kav dej kub hauv pej xeem.
