CPE， Ko te polyethylene chlorinated, e mōhiotia ana ko te polyethylene chlorinated, he mea hanga mai i te polyethylene motuhake kiato-teitei (HDPE) mā te tukanga chlorination. Ko te āhuatanga o tēnei rauemi ko te whakakapinga wāhanga o ngā ngota hauwai i roto i tōna mekameka ngota ngota e ngā ngota hauwai, e whakaatu ana i tētahi hanganga matū ahurei. Ka puta te CPE maroke hei paura mā, ā, kāore he paitini, he haumaru hoki. Ko tōna tauira ngota ngota ko CH2-CHCl-CH2-CH2]n, e whakarapopototia ana ko CPE, CM rānei i te reo Ingarihi. Hei rauemi polymer kua mākū, ehara i te mea he pai te ātete o te CPE ki te huarere me te ātete mura, engari he tino pai te pumau o te wera, he mea tino pai ake i te PVC. Hei tāpiri, he iti te utu me te mahi pai. Mō te wairewa, ka wairewa te CPE i roto i ngā hauwaiwaro kakara me ngā hauwaiwaro halogenated, engari kāore e wairewa i roto i ngā hauwaiwaro aliphatic. Ina neke ake te pāmahana i te 170 ℃, ka tīmata te pirau me te tuku i te hau hauwaiwaro hauwaiwaro. Nā tōna hanganga matū pumau, he pai hoki te ātete koroheketanga o te CPE, te ātete makariri, te ātete matū, te ātete ozone, me te whakamarumaru hiko. I taua wā anō, he pai hoki te hototahi me te ngāwari ki te tukatuka, ā, ka taea te whakaranu ki ngā rauemi pēnei i te PVC, PE, PS, me te rapa, kia pai ake ai ngā āhuatanga ā-tinana o ēnei rauemi.
He whānuitia ngā tono a te CPE i roto i ngā mara maha
1. Te tono i roto i te kiriuhi ārai wai
Ko te kiriuhi ārai wai PVC whakarei ake a te CPE, me ōna āhuatanga tino pai o te CPE, kua tino whakanuia tōna kaha kume mā te 80% me tōna kaha haehae mā te 50%. I taua wā anō, kua tino whakareihia hoki tōna ātete ki te huarere ā-pūkaha, te ātete ki te pāmahana iti, me te ātete ki te koroheketanga, ā, he tino pai ki ngā tari hanga (me te tāpiri CPE e whakahaeretia ana i te 10% -15%). Hei tāpiri, ko te kiriuhi ārai wai rapa chloroprene CPE me te kiriuhi ārai wai rapa styrene butadiene CPE rapa chloroprene kua noho hei whakatupuranga hou o ngā rauemi ārai wai tino pai me ō rātou kaha teitei, te ngāwari teitei, te whānui teitei, me ngā painga maha pērā i te ātete ki te waikura, te ātete ki te pāmahana teitei, te ātete ki te makariri, te ātete ki te koroheketanga, me te ātete ki te mura, ā, he whānui ngā tirohanga mākete.
2. Te hanga o ngā tatau me ngā matapihi kirihou
Mā te whakaranu i te CPE me te PVC, ka tino pai ake te ngāwari, te pakari, me te mahi pāmahana iti o ngā tatau me ngā matapihi kirihou, ā, he pai hoki te ātete ki te huarere, te ātete ki te wera, me te pumau matū. He utu tika tēnei momo tatau me ngā matapihi kirihou, he ātete ki te waikura, ā, he maha ngā tae e wātea ana. Ki te whakatauritea ki ngā tatau me ngā matapihi konumohe, he nui ake ngā painga, ā, kua piki haere te rongonui i te mākete.
3. Te whakamahinga o te uhi waea me te taura
Nā te tāpiri o te CPE kua pai ake te mahi tahunga katote, te mahi ārai-pakeketanga me ngā āhuatanga ā-tinana me ā-pūkaha o ngā uhi waea me ngā taura. I taua wā anō, he tino pai te mahi a ngā rauemi takai waea me ngā taura i hangaia i te nuinga o te wā mai i te CPE.
4. Te hanga i ngā ngongo rapa me ngā kapu hu
Ka taea e te CPE te hanga i ngā ngongo he ātete ki te hinu, te waikawa, te piko, te ozone, me te Freon, ā, he pai hoki mō te hanga i ngā ngongo waipēhi, ngā ngongo whakamatao, ngā ngongo wahie, me ētahi atu. I taua wā anō, ko te kapu hiako kau rūpahu i hangaia me te CPE hei tinana matua e whakaatu ana i te mahi tino pai.
