Njirimara na ojiji dị iche iche nke CPE chlorine polyethylene

CPE, A na-eji polyethylene pụrụ iche nke nwere oke njupụta (HDPE) eme polyethylene a na-akpọ chlorine polyethylene site na usoro chlorine. Ihe e ji mara ihe a bụ na atọm chlorine dochie atọm hydrogen dị na yinye molekul ya, na-egosi nhazi kemịkalụ pụrụ iche. CPE kpọrọ nkụ na-apụta dị ka ntụ ọcha ma ọ naghị egbu egbu ma dịkwa mma. Usoro molekul ya bụ CH2-CHCl-CH2-CH2] n, nke a na-akpọ CPE ma ọ bụ CM na Bekee. Dịka ihe polymer juru eju, CPE abụghị naanị na ọ nwere ezigbo iguzogide ihu igwe na iguzogide ire ọkụ, kamakwa ọ na-egosipụta nkwụsi ike okpomọkụ dị mma, nke pụtara ìhè karịa PVC. Na mgbakwunye, ọ nwekwara uru nke obere ọnụ ahịa na arụmọrụ dị mma. N'ihe gbasara mgbaze, CPE na-agbaze na hydrocarbons aromatic na halogenated hydrocarbons, mana ọ naghị agbaze na hydrocarbons aliphatic. Mgbe okpomọkụ gafere 170 ℃, ọ na-amalite ịgbaze ma wepụta gas hydrogen chloride. N'ihi nhazi kemịkalụ ya siri ike, CPE na-egosipụtakwa iguzogide ịka nká dị mma, iguzogide oyi, iguzogide kemịkalụ, iguzogide ozone, na mkpuchi eletriki. N'otu oge ahụ, ọ nwekwara ezigbo ndakọrịta na nhazi, enwere ike ijikọta ya na ihe dịka PVC, PE, PS, na roba, na-eme ka ihe ndị a dịkwuo mma nke ọma.
CPE nwere ọtụtụ ngwa dị iche iche n'ọtụtụ ubi
1. Ngwa na akpụkpọ ahụ na-egbochi mmiri
Akpụkpọ ahụ CPE nke na-egbochi mmiri PVC, nke nwere njirimara dị mma nke CPE, emeela ka ike nrụgide ya dịkwuo elu site na 80% na ike ndọda site na 50%. N'otu oge ahụ, iguzogide ihu igwe ya, obere iguzogide okpomọkụ, na iguzogide ịka nká amụbaala nke ọma, ngalaba owuwu na-akwadokwa ya nke ukwuu (yana mgbakwunye CPE na-achịkwa na 10% -15%). Na mgbakwunye, akpụkpọ ahụ na-egbochi mmiri CPE nke roba chloroprene na akpụkpọ ahụ na-egbochi mmiri CPE nke roba chloroprene styrene butadiene aghọọla ọgbọ ọhụrụ nke ihe ndị na-egbochi mmiri zuru oke nwere ike dị elu, ike dị elu, ike ịgbatị elu, yana ọtụtụ uru dị ka iguzogide nchara, iguzogide okpomọkụ dị elu, iguzogide oyi, iguzogide ịka nká, na mgbochi ire ọkụ, ma nwee atụmanya ahịa sara mbara.
2. Mmepụta ọnụ ụzọ na windo plastik
Site na ijikọta CPE na PVC, ọnụ ụzọ na windo plastik na-agbanwe agbanwe, ike siri ike, na arụmọrụ okpomọkụ dị ala na-akawanye mma nke ukwuu, ebe ha nwekwara ezigbo iguzogide ihu igwe, iguzogide okpomọkụ, na nkwụsi ike kemịkalụ. Ụdị ọnụ ụzọ na windo plastik a dị ọnụ ala, na-eguzogide nchara, ma na-abịa n'ọtụtụ agba. Ma e jiri ya tụnyere ọnụ ụzọ na windo alloy aluminum, ọ nwere uru karịa ma jiri nwayọọ nwayọọ ghọọ ihe ọhụrụ a na-ahụkarị n'ahịa.
3. Itinye waya na eriri mkpuchi
Mgbakwunye nke CPE emeela ka arụmọrụ ọkụ cathodic dịkwuo mma, arụmọrụ mgbochi ịka nká, yana njirimara anụ ahụ na nke mekaniki nke waya na eriri mkpuchi. N'otu oge ahụ, ihe mkpuchi waya na eriri ejiri CPE mee na-egosipụtakwa arụmọrụ dị mma.
4. Mmepụta paịpụ rọba na ụkwụ akpụkpọ ụkwụ
CPE nwere ike imepụta paịpụ ndị na-eguzogide mmanụ, asịd, gbagọrọ agbagọ, ozone, na Freon, ma dabara adaba maka imepụta paịpụ hydraulic, paịpụ oyi, paịpụ mmanụ ọkụ, na ihe ndị ọzọ. N'otu oge ahụ, akpụkpọ anụ ehi e ji CPE mee na-egosipụtakwa arụmọrụ dị mma.
