ʻO ka chlorinated polyethylene (CPE) kahi mea polymer saturated, ke ʻano o ka pauka keʻokeʻo, ʻaʻohe mea ʻona a me ka ʻono ʻole, me ke kūpaʻa maikaʻi o ka wā, ke kū ʻana o ka ozone, ke kūpaʻa kemika a me ka pale ʻana i ka wā kahiko, me ke kūpaʻa aila maikaʻi, ka lapalapa ahi a me nā waiwai kala.ʻO ka paʻakikī maikaʻi (hiki ke maʻalahi i -30 ℃), hiki ke hoʻopili maikaʻi me nā mea polymer ʻē aʻe, ka wela decomposition kiʻekiʻe, ka decomposition o HCl, hiki i ka HCl ke hoʻololi i ka hopena dechlorination o CPE.
Inoa Kūʻokoʻa: Chlorinated Polyethylene, Abbreviation: CPE, Chlorinated polyethylene he mea polymer i hoʻomākaukau ʻia mai ka polyethylene kiʻekiʻe kiʻekiʻe (HDPE) e ka hopena hoʻololi chlorination.E like me ka ʻokoʻa a me ka hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia ka polyethylene chlorinated i loko o ka resin chlorinated polyethylene (CPE) a me ka elastic type chlorinated polyethylene (CM) ʻelua mau ʻāpana.Ma waho aʻe o ka hoʻohana wale ʻia, hiki ke hui pū 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 pāpaʻi, hiki ke hoʻohana ʻia ka CPE ma ke ʻano he lāʻau kūikawā kiʻekiʻe, kiʻekiʻe, a hiki ke hui pū ʻia me ka ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile butadiene rubber (NBR), chlorosulfonated polyethylene ( CSM) a me nā mea ʻē aʻe.
ʻAno CPE
1, ʻO CPE kahi ʻano saturated rubber, maikaʻi loa ka pale ʻana i ka wela o ka oxygen aging, ozone aging, acid and alkali resistance, chemical properties.
2, he laulā ke kū'ē o ka aila o CPE, a he maika'i ke kū'ē i ka aila ASTM 1 a me ka aila ASTM 2, e like me ka NBR;Kūleʻa maikaʻi loa i ka ʻaila ASTM 3, ʻoi aku ka maikaʻi ma mua o CR, a hoʻohālikelike ʻia me CSM.
3, Loaʻa i ka CPE ka chlorine, maikaʻi loa ka hana ʻana o ka lapalapa ahi, a loaʻa nā ʻano anti-drip combustion.Hiki ke loa'a ka mea ho'opa'a ahi me ka hana ho'opa'a ahi maika'i a me ke kumu kū'ai ha'aha'a e ka māhele kūpono o ka pale ahi antimony, chlorinated paraffin a me Al(OH)3.
4. ʻAʻole ʻawaʻawa ʻo CPE, ʻaʻole i loko o nā metala kaumaha a me nā PAH, a hoʻokō pono i nā koi kaiapuni.
5, Loaʻa i ka CPE ka hoʻopiha piha piha ʻana, hiki ke mākaukau e hoʻokō i nā ʻano hana like ʻole o ka huahana.Loaʻa ka CPE i ka hana hoʻoponopono maikaʻi a loaʻa ka viscosity Mooney i nā ʻano papa ma waena o 50-100.
