Chlorinated polyethylene (CPE) yog cov khoom siv polymer saturated, zoo li cov hmoov dawb, tsis muaj tshuaj lom thiab tsis qab, nrog rau huab cua tsis zoo, ozone tsis kam, tshuaj tiv thaiv thiab kev laus, nrog rau cov roj zoo, nplaim hluav taws thiab xim xim.Zoo toughness (tseem hloov tau ntawm -30 ℃), muaj kev sib raug zoo nrog lwm cov ntaub ntawv polymer, siab decomposition kub, decomposition ntawm HCl, HCl tuaj yeem ua rau cov tshuaj tiv thaiv dechlorination ntawm CPE.
Lub Npe Lub Npe: Chlorinated Polyethylene, Cov Lus Cim: CPE, Chlorinated polyethylene yog cov khoom siv polymer npaj los ntawm high density polyethylene (HDPE) los ntawm chlorination hloov cov tshuaj tiv thaiv.Raws li cov qauv sib txawv thiab kev siv, chlorinated polyethylene tuaj yeem muab faib ua chlorinated polyethylene (CPE) thiab elastic hom chlorinated polyethylene (CM) ob pawg.Ntxiv rau kev siv ib leeg, cov khoom siv thermoplastic kuj tuaj yeem sib xyaw nrog polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS thiab txawm tias polyurethane (PU).Hauv kev lag luam roj hmab, CPE tuaj yeem siv los ua cov khoom lag luam zoo, cov roj hmab tshwj xeeb zoo, thiab tuaj yeem sib xyaw nrog ethylene propylene roj hmab (EPR), butyl roj hmab (IIR), nitrile butadiene roj hmab (NBR), chlorosulfonated polyethylene ( CSM) thiab lwm yam roj hmab.
CPE Trait
1, CPE yog ib hom roj hmab saturated, muaj kev tiv thaiv zoo heev ntawm cov pa oxygen aging, ozone aging, acid thiab alkali tsis kam, tshuaj lom neeg.
2, cov roj tsis kam ntawm CPE yog qhov dav dav, thiab kev ua haujlwm rau ASTM 1 roj thiab ASTM 2 roj zoo heev, uas yog sib npaug rau NBR;Kev tiv thaiv zoo rau ASTM 3 roj, zoo dua CR, thiab piv rau CSM.
3, CPE muaj cov tshuaj chlorine, muaj cov nplaim hluav taws zoo heev, thiab muaj cov yam ntxwv tiv thaiv drip.Cov khoom siv hluav taws xob hluav taws xob nrog cov nplaim hluav taws zoo ua haujlwm thiab tus nqi qis tuaj yeem tau txais los ntawm qhov tsim nyog ntawm cov nplaim hluav taws kub hnyiab, chlorinated paraffin thiab Al (OH) 3.
4. CPE tsis muaj tshuaj lom, tsis muaj cov hlau hnyav thiab PAHs, thiab ua tau raws li qhov xav tau ntawm ib puag ncig.
5, CPE muaj kev ua haujlwm siab, tuaj yeem npaj kom tau raws li ntau yam kev ua haujlwm sib txawv ntawm cov khoom.CPE muaj kev ua haujlwm zoo thiab Mooney viscosity muaj nyob rau ntau qib ntawm 50-100.
