I roto i to maatau oranga, ko te CPE me te PVC he nui ake te whakamahi.Ko te polyethylene maaota he rauemi polymer kukū me te ahua o te paura ma, kaore i te paitini me te kore reka, he tino pai te parenga huarere, te atete ozone, te aukati matū me te ātete tawhito.Mahinga, he pai te aukati hinu, te mura o te mura me nga ahuatanga tae.He pai te pakari (he ngawari tonu i te -30°C), he pai te hototahi ki etahi atu rauemi polymer, me te teitei o te pāmahana pirau.Ko te polyethylene kua maaota he rauemi waerau i hangaia mai i te polyethylene teitei (HDPE) na roto i te tauhohenga whakakapi maaota.E ai ki nga hanganga me nga whakamahinga rereke, ka taea te wehewehe i te polyethylene chlorinated ki nga waahanga e rua: polyethylene chlorinated-momo (CPE) me te polyethylene chlorinated-momo elastomer (CM).I tua atu i te whakamahia anake, ka taea hoki te whakakotahi i nga kapia thermoplastic ki te polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS me te polyurethane (PU).I roto i te ahumahi rapa, ka taea te whakamahi CPE hei rapa motuhake, he kounga teitei, ka taea hoki te whakamahi me te rapa ethylene-propylene (EPR), te rapa butyl (IIR), te rapa nitrile (NBR), te polyethylene chlorosulfonated ( CSM), me etahi atu. Ka whakamahia etahi atu ranunga rapa.
I te tekau tau atu i 1960, ko te kamupene Tiamana Hoechst i angitu te whakawhanake me te mohio ki nga mahi ahumahi.I timata taku whenua ki te whakawhanake i te polyethylene chlorinated i te mutunga o nga tau 1970.Ko te "Aqueous Phase Suspension Synthesis of CPE Technology" i angitu tuatahi i whakawhanakehia e te Anhui Chemical Industry Research Institute, me nga taputapu hanga o 500-1000t / a me nga pauna rereke kua hangaia i Wuhu, Anhui, Taicang, Jiangsu, me Weifang, Shandong .
Ko te kaha o te hinu o te CPE he toharite, i roto i nga mea e pai ana te aukati ki te hinu ASTM Nama 1 me te hinu ASTM Nama 2, he rite ki te NBR;he pai rawa atu te aukati ki te hinu ASTM Nama 3, pai ake i te CR, he rite ki te CSM.
Kei roto i te CPE te chlorine, he pai rawa nga ahuatanga o te mura o te mura me nga ahuatanga o te wera me te aukati i te pupuhi.Ka taea te whakakotahi ki te parenga mura-a-antimony, paraffin chlorinated, me te Al(OH)3 i roto i te ōwehenga e tika ana ki te whiwhi i tetahi rauemi mura-muri me te pai o te mahi mura me te utu iti.
Ko te CPE kaore he paitini, kaore he konganuku taumaha me te PAHS, ka tutuki katoa nga whakaritenga tiaki taiao.
He nui nga mahi whakakii a CPE ka taea te hanga hei hua e tutuki ana i nga momo whakaritenga mahi.He pai te mahinga o te CPE, ko te pokey Mooney (ML121 1+4) kei waenga i te 50-100, a he maha nga tohu hei whiriwhiri mai.
