1. Ko te polyethylene chlorinated, e mōhiotia ana ko CPE i te reo Pākehā, he momo polyethylene. Ko te polyethylene chlorinated (CPE) he rauemi i whiwhi mā te whakakapi wāhanga i ngā ngota hauwai i runga i te polyethylene kiato-teitei (HDPE) ki ngā ngota chlorine. Ka puta te CPE hei paura mā, kāore he paitini, kāore hoki he kakara.
2. He pai ake te ātete o te polyethylene chlorine i hangaia mai i te polyethylene pēhanga iti HDPE ki te pāmahana teitei me te koroheketanga wera nui atu i te polyethylene chlorine i hangaia mai i te polyethylene pēhanga teitei. Ko te tikanga, ko te polyethylene he 0.93-0.96g/cm3 te matotoru, ko te taumaha ngota toharite o te 50000 ki te 250000, me te taupū rewa i waenga i te 0.01 me te 2.0g/10min te mea e whakamahia whānuitia ana hei hanga polyethylene chlorine. He pānga nui te nui o te chlorine o te polyethylene chlorine ki ōna āhuatanga. Ina iti iho te ihirangi chlorine i te 15%, he kirihou; Ina 16-24% te ihirangi chlorine, he elastomer thermoplastic; he elastomer rite ki te rapa me te ihirangi chlorine i waenga i te 25-48%; Ina 49-58% te ihirangi chlorine, he polymer mārō āhua-pūmau rite ki te hiako; Ina eke te ihirangi chlorine ki te 73%, ka huri hei kapia pakarukaru. Mā te whakauru i te 27% o te haukini ki roto i te polyethylene pēhanga teitei ka whakakorea rawatia te tioata, ā, mā te whakauru i te 30% o te haukini ki roto i te polyethylene pēhanga iti me te tioata teitei ake ka whakakorea rawatia hoki te tioata. Hei elastomer rapa, ko te nui o te haukini kei roto i te awhe 30-40%. I tēnei wā, ko te nui o te haukini o te rapa polyethylene arumoni kua whakakīia ki te haukini kei roto i te awhe 25-45%. Ina piki ake te nui o te haukini, ka pai ake te ātete hinu, te āheinga manawa, me te ātete mura; ina heke te nui o te haukini, ka pai ake te ātete makariri, te manawanui, me te mahi piko pēhanga.
2. Ngā Āhuatanga o te CPE Polyethylene Chlorinated
1) He rapa kukū te CPE, he ātete pai ki te wera me te hāora tawhito, ki te ōzone tawhito, ki te waikawa me te kawakore, me ngā āhuatanga matū anō hoki.
2) He tino pai te ātete hinu o te CPE, he tino pai te ātete ki te hinu ASTM 1 me te hinu ASTM 2, he rite ki te NBR; he tino pai te ātete ki te hinu ASTM Nama 3, he pai ake i te CR, ā, he rite ki te CSM.
3) Kei roto i te CPE te huānga chlorine, he āhuatanga pai rawa atu mō te ārai i te mura, ā, he āhuatanga mura, ārai hoki i te maturuturu. Ka taea te whakakotahi me ngā ārai mura e ahu mai ana i te antimony, te paraffin chlorine, me te Al (OH) 3 i ngā ōwehenga tika hei whiwhi rauemi ārai mura me te ārai mura pai rawa atu, me te utu iti.
4) Kāore he paitini o te CPE, kāore he konganuku taumaha me ngā PAH, ā, e tutuki katoa ana i ngā whakaritenga taiao.
5) He tino pai te mahi whakakī a te CPE, ā, ka taea e ia te whakaputa hua e tutuki ana i ngā whakaritenga mahi maha. He pai te mahi tukatuka a te CPE, ā, he maha ngā momo hei whiriwhiri māu me te matotoru Mooney i waenga i te 50-100.
