ʻO ka polyethylene chlorinated (CPE) a mākou i kamaʻāina ai

I ko mākou ola, ʻoi aku ka nui o ka hoʻohana ʻia ʻana o CPE a me PVC. ʻO ka polyethylene chlorinated kahi mea polymer saturated me ke ʻano o ka pauka keʻokeʻo, ʻaʻohe ʻawaʻawa a ʻono ʻole, a he kūpaʻa maikaʻi loa i ka wā, ke kūpaʻa ozone, ke kūpaʻa kemika a me ke kūpaʻa ʻelemakule. Hana, me ke kūpaʻa aila maikaʻi, ka pale ʻana i ka lapalapa a me nā waiwai kala. Paʻakikī maikaʻi (hiki ke loli ma -30°C), kūpono maikaʻi me nā mea polymer ʻē aʻe, a me ka mahana decomposition kiʻekiʻe. ʻO ka polyethylene chlorinated kahi mea polymer i hana ʻia mai ka polyethylene density kiʻekiʻe (HDPE) ma o kahi hopena pani chlorination. Wahi a nā ʻano like ʻole a me nā hoʻohana, hiki ke hoʻokaʻawale ʻia ka polyethylene chlorinated i ʻelua mau māhele: resin-type chlorinated polyethylene (CPE) a me elastomer-type chlorinated polyethylene (CM). Ma waho aʻe o ka hoʻohana wale ʻia ʻana, hiki ke hoʻohui ʻia nā resins thermoplastic me ka polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS a me ka polyurethane (PU). I loko o ka ʻoihana laholio, hiki ke hoʻohana ʻia ʻo CPE ma ke ʻano he laholio kūikawā hana kiʻekiʻe, a hiki ke hoʻohana pū ʻia me ka laholio ethylene-propylene (EPR), ka laholio butyl (IIR), ka laholio nitrile (NBR), ka polyethylene chlorosulfonated (CSM), a pēlā aku. Hoʻohana ʻia nā hui laholio ʻē aʻe.
I nā makahiki 1960, ua hoʻomohala mua ka hui Kelemania ʻo Hoechst a hoʻokō i ka hana ʻoihana. Ua hoʻomaka koʻu ʻāina e hoʻomohala i ka polyethylene chlorinated i ka hopena o nā makahiki 1970. Ua hoʻomohala mua ʻia ka "Aqueous Phase Suspension Synthesis of CPE Technology" e ka Anhui Chemical Industry Research Institute, a ua kūkulu ʻia nā mea hana o 500-1000t/a me nā unahi like ʻole ma Wuhu, Anhui, Taicang, Jiangsu, a me Weifang, Shandong.
He awelika ke kūpaʻa ʻaila o CPE, ʻo ia hoʻi ke kūpaʻa ʻana i ka ʻaila ASTM No. 1 a me ka ʻaila ASTM No. 2 he maikaʻi loa, e like me NBR; ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka ʻaila ASTM No. 3, ma mua o CR, e like me CSM.
Loaʻa i ka CPE ka chlorine, nona nā waiwai pale lapalapa maikaʻi loa a he mau ʻano o ke kuni a me ka pale ʻana i ka dripping. Hiki ke hoʻohui ʻia me ka pale lapalapa antimony, ka paraffin chlorinated, a me Al(OH)3 i kahi ratio kūpono e loaʻa ai kahi mea pale lapalapa me ka hana pale lapalapa maikaʻi loa a me ke kumukūʻai haʻahaʻa.
ʻAʻohe mea ʻawahia o ka CPE, ʻaʻohe ona metala kaumaha a me nā PAHS, a hoʻokō piha i nā koi palekana o ke kaiapuni.
He kiʻekiʻe ka hana hoʻopiha ʻana o CPE a hiki ke hana ʻia i nā huahana e hoʻokō ana i nā koi hana like ʻole. He maikaʻi ka hana ʻana o CPE, ʻo ka mānoanoa o Mooney (ML121 1+4) ma waena o 50-100, a he nui nā māka e koho ai.
