1. Polyethylene a na-akpọ CPE n'asụsụ Bekee, bụ ụdị polyethylene. Polyethylene a na-akpọ Chlorin (CPE) bụ ihe e nwetara site na iji atọm chlorine dochie atọm hydrogen na polyethylene dị elu (HDPE). CPE na-apụta dị ka ntụ ọcha, ọ naghị egbu egbu ma na-enweghị isi.
2. Polyethylene a kpụchara akpụcha nke e ji obere nrụgide mee nke e ji polyethylene HDPE dị ala mee nwere ike iguzogide okpomọkụ dị elu na ịka nká nke okpomọkụ karịa polyethylene a kpụchara akpụcha nke e ji nnukwu nrụgide mee. N'ozuzu, a na-ejikarị polyethylene nwere njupụta nke 0.93-0.96g/cm3, nkezi ịdị arọ molekul nke 50000 ruo 250000, na ndeksi agbaze n'etiti 0.01 na 2.0g/10min emepụta polyethylene a kpụchara akpụcha. Ogo nke chlorination nke polyethylene a kpụchara akpụcha nwere mmetụta dị ukwuu na ihe onwunwe ya. Mgbe ọdịnaya chlorine erughị 15%, ọ bụ plastik; Mgbe ọdịnaya chlorine dị 16-24%, ọ bụ elastomer thermoplastic; Elastomer dị ka rọba nwere ọdịnaya chlorine n'etiti 25-48%; Mgbe ọdịnaya chlorine dị 49-58%, ọ bụ polymer siri ike nke ọkara yiri akpụkpọ anụ; Mgbe ọdịnaya chlorine ruru 73%, ọ na-aghọ resin na-agbawa agbawa. Ntinye ihe dị ka chlorine 27% n'ime polyethylene nwere nrụgide dị elu na-ewepụ kristal kpamkpam, ebe itinye ihe dị ka chlorine 30% n'ime polyethylene nwere nrụgide dị ala nke nwere kristal dị elu na-ewepụkwa kristal kpamkpam. Dịka elastomer roba, ọdịnaya chlorine kacha mma n'ime oke 30-40%. Ugbu a, ọdịnaya chlorine nke roba polyethylene a na-ere ahịa na-adịkarị n'etiti 25-45%. Mgbe ọdịnaya chlorine na-abawanye, iguzogide mmanụ, iku ume, na mbelata ọkụ na-akawanye mma; Mgbe ọdịnaya chlorine na-ebelata, iguzogide oyi, iguzogide, na arụmọrụ mgbagọ nrụgide na-aka mma.
2. Àgwà nke Polyethylene CPE nke a na-akpọ Chlorined
1) CPE bụ roba jupụtara nke nwere ezigbo iguzogide okpomọkụ na ikuku oxygen, iguzogide ịka nká ozone, iguzogide acid na alkali, yana ihe ndị metụtara kemịkalụ.
2) CPE nwere ezigbo nguzogide mmanụ, yana ezigbo nguzogide mmanụ ASTM 1 na mmanụ ASTM 2, nke yiri NBR; Nguzogide dị mma na mmanụ ASTM Nke 3, dị elu karịa CR ma yie CSM.
3) CPE nwere ihe chlorine, nke nwere ezigbo ihe mgbochi ire ọkụ ma nwee njirimara ọkụ na mgbochi ntapụ mmiri. Enwere ike ijikọta ya na ihe mgbochi ire ọkụ dabere na antimony, paraffin chlorine, na Al (OH) 3 n'ogo kwesịrị ekwesị iji nweta ihe mgbochi ire ọkụ nke nwere ezigbo mgbochi ire ọkụ na ọnụ ala dị ala.
4) CPE anaghị egbu egbu, enweghị ọla dị arọ na PAH, ma na-emezu ihe niile achọrọ maka gburugburu ebe obibi.
5) CPE nwere arụmọrụ dị elu nke na-ejupụta ihe ma nwee ike imepụta ngwaahịa ndị na-emezu ihe dị iche iche achọrọ maka arụmọrụ. CPE nwere arụmọrụ nhazi dị mma, enwerekwa ọtụtụ ọkwa ịhọrọ site na ya na oke viscosity nke Mooney dị n'etiti 50-100.
