Chlorinated polyethylene yog cov khoom siv polymer ua los ntawm polyethylene yas (HDPE) uas yog chlorinated es tsis txhob reacted. Chlorinated polyethylene tuaj yeem muab faib ua resin chlorinated polyethylene (CPE) thiab elastic chlorinated polyethylene polyethylene (CM) ob hom no. Hauv qab no yog cov yam ntxwv ua haujlwm ntawm chlorinated polyethylene.
Chlorinated polyethylene (CPE lossis CM luv luv) yog cov khoom siv hluavtaws polymer hloov los ntawm chlorination ntawm polyethylene. Nws muaj qhov ua tau zoo, kev laus tiv thaiv tshav kub, kev nyab xeeb thiab kev tiv thaiv ozone, vim nws cov qauv molecular yog linear saturation thiab cov qauv tsis sib xws. Cov mis mos molecular muaj ib feem loj ntawm cov tshuaj chlorine, yog li nws muaj roj zoo, tshuaj tiv thaiv thiab nplaim hluav taws. Cov khoom ntawm chlorinated polyethylene sib txawv heev nyob ntawm txoj kev tsim khoom thiab ntau yam ntawm raw polyethylene. Cov yam ntxwv tseem ceeb rau cov khoom ntawm raw polyethylene ntau yam yog cov ntsiab lus chlorine, chlorine faib thiab siv lead ua zoo li.
Cov khoom siv raw ntau yam thiab cov yam ntxwv ntawm polyethylene tswj cov khoom ua haujlwm thiab lub cev thiab cov khoom siv ntawm chlorinated polyethylene. Chlorination theem muaj kev cuam tshuam zoo rau chlorinated polyethylene, thaum cov ntsiab lus chlorine tsawg dua 15%, nws yog yas; Cov ntsiab lus chlorine ntawm 16 ~ 24% ntawm cov thermoplastic elastomers; Cov ntsiab lus chlorine yog 25 ~ 48% rau roj hmab elastomers; Cov ntsiab lus chlorine ntawm 49 ~ 58% zoo ib yam li tawv semi-elastic tawv polymer; Thaum cov ntsiab lus chlorine siab li 73%, nws dhau los ua cov nkig.
Qhov sib txawv ntawm kev faib cov tshuaj chlorine thiab siv lead ua ua rau muaj qhov sib txawv ntawm cov khoom siv lub cev thiab cov khoom ua haujlwm ntawm cov roj hmab.
