Nā Mea Hana CPE Polyethylene Chlorinated
E hoʻolauna ka mea hoʻoponopono o ka mea hana anti-aging iā ʻoe i kēia lā i ka hoʻolauna pili e pili ana i ka mea hana o ka chlorinated polyethylene cpe. ʻO ka chlorinated polyethylene (CPE) kahi huahana i hoʻohana ʻia i ka hana kemika. ʻAʻole ʻike ka nui o ka poʻe e pili ana i ka vinyl chloride chloride. E hoʻomaopopo, ʻo ka pōkole Pelekania o ka chlorinated polyethylene ʻo: CPE a i ʻole cm, ʻo ka chlorinated polyethylene (CPE) kahi mea polymer saturated, he pauka keʻokeʻo ke ʻano, ʻaʻohe ʻawaʻawa a ʻono ʻole, me ke kūpaʻa maikaʻi loa i ka wā, ke kūpaʻa ozone, ke kūpaʻa kemika a me ke kūpaʻa ʻana i ka ʻelemakule, ke kūpaʻa aila maikaʻi, ka pale ʻana i ka lapalapa a me nā waiwai pale kukui. ʻO ka paʻakikī maikaʻi (hiki ke loli ma -30°C), kūpono maikaʻi me nā mea polymer ʻē aʻe, ka mahana decomposition kiʻekiʻe, ka decomposition o HCl, hiki i ka HCl ke hoʻoulu i ka hopena dechlorination o CPE.
ʻO ka polyethylene chlorinated (HDPE) kahi mea polymer i hana ʻia mai ka polyethylene kiʻekiʻe-density (HDPE) ma o ka chlorination. Wahi a nā ʻano like ʻole a me nā hoʻohana, hiki ke hoʻokaʻawale ʻia ka polyethylene chlorinated i ka resin chlorinated polyethylene (CPE) a me ka elastic chlorinated polyethylene (CM). Ma waho aʻe o nā resins thermoplastic hiki ke hoʻohana wale ʻia, hiki ke hui pū ʻia me ka polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin a me ka polyurethane (PU). I loko o ka ʻoihana laholio, hiki ke hoʻohana ʻia ʻo CPE ma ke ʻano he laholio kūikawā kiʻekiʻe, kiʻekiʻe ke ʻano, a hiki ke hoʻohana ʻia me ka laholio ethylene-propylene (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM) E hoʻohana me nā hui laholio ʻē aʻe.
Nā Waiwai o ka Polyethylene Chlorinated
1) ʻAʻohe mea ʻawahia ka CPE, ʻaʻohe ona metala kaumaha a me nā hydrocarbons aromatic polycyclic, a hoʻokō piha i nā koi palekana kaiapuni.
2) He kūpaʻa maikaʻi loa ko CPE i ka ʻaila, ʻoi aku hoʻi nā ʻaila ASTM1 a me ASTM2, e like me NBR; kūpaʻa maikaʻi loa i nā ʻaila ASTM3, ʻoi aku ka maikaʻi ma mua o CR a hoʻohālikelike ʻia me CSM.
3) Loaʻa i ka CPE ka hana hoʻopiha kiʻekiʻe a hiki ke hana ʻia i nā huahana e hoʻokō ai i nā koi hana like ʻole. Loaʻa i ka CPE ka mīkini maikaʻi loa a loaʻa i nā māka viscosity Mooney (ML1211+4) mai 50 a 100.
4) He laholio piha ʻo CPE me ka ʻelemakule anti-oxidative maikaʻi loa, ka ʻelemakule anti-ozone, ke kūpaʻa waikawa a me ka alkali a me nā waiwai kemika.
5) Loaʻa i ka CPE nā mea chlorine, he mau waiwai pale lapalapa maikaʻi loa, a he mau ʻano o ka puhi ʻana i ka drip. Hoʻohana pū ʻia ka pale lapalapa antimony, ka paraffin chlorinated a me Al(OH)3 i kahi kūpono e loaʻa ai kahi mea pale lapalapa me ka hana pale lapalapa maikaʻi a me ke kumukūʻai haʻahaʻa.
