Hoʻopau ʻia ka polyethylene e like me PE, ʻo ia ke ʻano o ka resin thermoplastic i hana ʻia e ka polymerization o ka ethylene.Ma ka ʻoihana, loaʻa pū kekahi copolymers o ka ethylene a me kahi liʻiliʻi o ka α-olefin.ʻO ka polyethylene he mea ʻala ʻole, ʻaʻohe mea ʻawaʻawa, manaʻo e like me ka wax, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (hiki ke piʻi ka mahana hoʻohana haʻahaʻa loa i -70 ~ -100 ℃), loaʻa ke kūpaʻa kemika maikaʻi, a hiki ke kū i ka hapa nui o nā waikawa a me nā alkalis (ʻaʻole kū i nā waiwai oxidizing. ) ʻakika), hiki ʻole ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe maʻamau i ka lumi wela, ka haʻahaʻa haʻahaʻa o ka wai, ka insulation uila maikaʻi loa;akā, paʻakikī loa ka polyethylene i ke koʻikoʻi o ke kaiapuni (nā hopena kemika a me nā hopena mechanical), a ʻaʻole maikaʻi ke kūpaʻa ʻana o ka wela.ʻOkoʻa nā waiwai o ka polyethylene mai kēlā me kēia ʻano, ma muli o ke ʻano molekala a me ka nui.Hiki ke hoʻohana ʻia nā ʻano hana like ʻole no ka loaʻa ʻana o nā huahana me nā ʻano like ʻole (0.91~0.96g/cm3).Hiki ke hana ʻia ka polyethylene e nā ʻano hana hoʻoheheʻe thermoplastic maʻamau (e ʻike i ka hana plastik).Loaʻa iā ia ka nui o nā mea hoʻohana, hoʻohana nui ʻia e hana i nā kiʻiʻoniʻoni, nā ipu, nā paipu, nā monofilaments, nā uea a me nā kaula, nā mea e pono ai i kēlā me kēia lā, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia e like me nā mea insulating kiʻekiʻe no nā TV, radar, etc.
Nā ʻano PE:
(1) LDPE: polyethylene haʻahaʻa haʻahaʻa, polyethylene kiʻekiʻe
(2) LLDPE: linear low density polyethylene
(3) MDPE: polyethylene densitas medium, resin bimodal
(4) HDPE: polyethylene kiʻekiʻe kiʻekiʻe, polyethylene haʻahaʻa haʻahaʻa
(5) UHMWPE: ʻO ka polyethylene kaumaha kiʻekiʻe kiʻekiʻe
(6) Polyethylene i hoʻololi ʻia: CPE, polyethylene pili kea (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (plastic), EVA, ethylene-butene copolymer, ethylene-other olefin (e like me octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH
ʻO kā mākou paipuhana ʻia me ka mea HDPE
