Nā mea hana CPE Polyethylene Chlorinated
ʻO ka mea hoʻoponopono o ka mea hana anti-aging agent e hoʻolauna iā ʻoe i kēia lā i ka hoʻolauna kūpono e pili ana i ka mea hana o chlorinated polyethylene cpe. ʻO ka polyethylene chlorinated (CPE) kahi huahana i hoʻohana ʻia i ka hana kemika. ʻAʻole ʻike ka poʻe he nui e pili ana i ka vinyl chloride chloride. E hoʻomaopopo, ʻo ka ʻōlelo Pelekane o ka chlorinated polyethylene: CPE a i ʻole cm, chlorinated polyethylene (CPE) kahi mea polymer saturated, ʻo ke ʻano he pauka keʻokeʻo, ʻaʻohe mea ʻawaʻawa a 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. , kaʻaila maikaʻi maikaʻi, ka lapalapa ahi a me nā mea pale māmā. ʻO ka paʻakikī maikaʻi (ʻoi aku ka maʻalahi ma -30 ° C), kūpono maikaʻi me nā mea polymer ʻē aʻe, ka wela decomposition kiʻekiʻe, decomposition o HCl, hiki i ka HCl ke catalyze i ka hopena dechlorination o CPE.
ʻO ka polyethylene chlorinated (HDPE) he mea polymer i hana ʻia mai ka polyethylene kiʻekiʻe (HDPE) e ka chlorination. Wahi a nā ʻano hana like ʻole a me ka hoʻohana ʻana, 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 iā lākou ke hui pū me ka polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin a me ka polyurethane (PU). I loko o ka ʻoihana pāpaʻi, hiki ke hoʻohana ʻia ka CPE ma ke ʻano he kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe kiʻekiʻe o ke kopa kūikawā, a hiki ke hoʻohana pū ʻia me ka ethylene-propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene ( CSM) E hoʻohana me nā mea ʻē aʻe.
Nā waiwai o ka Polyethylene Chlorinated
1) ʻAʻole ʻawaʻawa ʻo CPE, ʻaʻohe metala kaumaha a me polycyclic aromatic hydrocarbons, a hoʻokō pono i nā koi palekana kaiapuni.
2) Loaʻa i ka CPE ke kūpaʻa aila maikaʻi loa, ʻoi aku ka nui o nā ʻaila ASTM1 a me ASTM2, e hoʻohālikelike ʻia me NBR; ke kū'ē maikaʻi loa i nā aila ASTM3, ʻoi aku ka maikaʻi ma mua o CR a hoʻohālikelike ʻia me CSM.
3) He kiʻekiʻe ka hoʻopiha piha ʻana o CPE a hiki ke hana ʻia i nā huahana e hoʻokō i nā koi hana like ʻole. He machinability maikaʻi loa ka CPE a loaʻa iā Mooney viscosity (ML1211+4) nā māka mai 50 a 100.
4) ʻO ka CPE kahi pahu saturated me ka maikaʻi anti-oxidative aging, anti-ozone aging, acid and alkali resistance a me nā waiwai kemika.
5) Loaʻa i ka CPE nā mea chlorine, loaʻa nā waiwai pale ahi maikaʻi loa, a loaʻa iā ia nā ʻano o ka anti-drip burning. Hoʻohana pū ʻia ka antimony-based flame retardant, chlorinated paraffin a me Al(OH)3 i kahi ʻāpana kūpono e loaʻa ai kahi mea pale ahi me ka hana maikaʻi ʻana i ka lapalapa ahi a me ke kumu kūʻai haʻahaʻa.
