Mmetụta nke mgbakwunye CPE na PVC

1, Atọ isi ihe na-emetụta CPE arụmọrụ
Mbụ, ọ bụ ụdị CPE eji. CPE enwetara site na polyethylene dị arọ dị elu nwere nnukwu viscosity na ike tensile, mana adhesion n'etiti CPE na resin PVC dị ala. CPE nwetara site na polyethylene dị ala dị ala nwere obere viscosity na ike ike, na CPE nwetara site na nnukwu njupụta polyethylene nwere ezigbo nguzogide okpomọkụ.
Nke abuo, ọ bụ nha nke akụrụngwa akụrụngwa. Mgbe urughuru size dị oke obere, ọ dị mfe na-etolite jelii ma ọ bụ clumpy CPE, na mgbe urughuru size bụ oke ibu, nkesa nke chlorine bụ unen.
Ọzọkwa, ọ bụ ọkwa CPE chlorination. Mgbe ọdịnaya chlorine dị n'okpuru 25%, ọ nwere ndakọrịta na-adịghị mma na PVC na enweghị ike iji ya mee ihe dịka mgbanwe; Mgbe ọdịnaya chlorine dị elu karịa 40%, ọ nwere ezigbo ndakọrịta na PVC ma nwee ike iji ya mee ihe dị ka plasticizer siri ike, ọ bụghị adabara dị ka ihe mgbanwe mmetụta; CPE nwere ọdịnaya chlorine nke 36-38% nwere ezigbo ngbanwe na ndakọrịta na PVC, na-eme ka a na-eji ya eme ihe n'ọtụtụ ebe dị ka ihe mgbanwe mmetụta maka PVC. Ugbu a, CPE nwere ọdịnaya chlorine nke 35% na-ejikarị. CPE nwere ọdịnaya chlorine nke gburugburu 35% nwere obere crystallinity na iko mgbanwe okpomọkụ, ezigbo mma rọba, yana ndakọrịta dabara na PVC. A na-eji ya eme ihe n'ọtụtụ ebe dị ka ihe ntụgharị mmetụta maka ngwaahịa PVC siri ike.
2. Mmetụta nke CPE mgbakwunye na PVC
Mgbe ego mgbakwunye dị n'okpuru 10 nkeji, ike mmetụta nke PVC na-abawanye ngwa ngwa na mgbakwunye nke CPE, ma na-abawanye ụba nke CPE na-eme ka ọ dịkwuo mma na ike mmetụta nke PVC. Ya mere, dị ka ihe mmetụta na-eguzogide ọgwụ, ego kwesịrị ekwesị nke CPE ka a ga-agbakwunye bụ akụkụ 8-10. Ka CPE na-abawanye, ike nkwụsị nke ngwakọta PVC na-aga n'ihu na-ebelata, ebe elongation na nkwụsịtụ na-abawanye. Ọ bụrụ na a na-egosipụta ike siri ike dị ka ngwaahịa nke ike nkwụsị na elongation na nkwụsịtụ, o doro anya na ike nke PVC ga-abawanye nke ọma na mmụba nke mgbakwunye CPE.
