ʻO ka ʻokoʻa ma waena o HDPE a me PE

ʻIke ʻia ʻo HDPE he mea polyethylene kiʻekiʻe.He ʻano resin thermoplastic me ka crystallinity kiʻekiʻe a me ka polarity ʻole.ʻO ka hiʻohiʻona o ka HDPE kumu he keʻokeʻo keʻokeʻo a me ka translucent i kekahi ʻano ma ka ʻāpana lahilahi.ʻAʻole hygroscopic ka polymer a he kūpaʻa maikaʻi ka mahu wai, hiki ke hoʻohana ʻia no nā kumu hoʻopili.Loaʻa i ka HDPE nā waiwai uila maikaʻi, ʻoi aku ka ikaika dielectric kiʻekiʻe o ka insulation, e kūpono loa ia no nā uea a me nā kaula.ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka pae molecular medium a hiki i ke kiʻekiʻe ma ka lumi wela a i ʻole -40f haʻahaʻa haʻahaʻa.Hoʻohana pinepine ʻia ʻo HDPE e like mepaipu paipu, a me kekahimea paani, Pk plug , leo.

Ma muli o ka ikaika like ʻole, pono nā paipu HDPE e hoʻokau i kekahi kaomi.ʻO ka mea maʻamau, pono ke koho ʻia nā resins PE me ke kaumaha molekala nui a me nā waiwai mechanical maikaʻi, e like me nā resins HDPE.He 9 manawa ka ikaika o ka paipu polyethylene maʻamau (pipe PE).

Heʻokoʻa ka pale lole.Ma waena o nā plastics ʻenekinia āpau, ʻo HDPE ka mea kiʻekiʻe loa o ka pale lole.ʻOi aku ka kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka ʻoi aku o ka ʻaʻahu a ʻoi aku ka nui o nā mea metala (e like me ke kila kalapona, ke kila kila, ke keleawe, a me nā mea ʻē aʻe), ʻo ka PE maʻamau he hoʻokahi hapaʻumi o HDPE.

Loaʻa i nā paipu HDPE nā hopena hoʻololi like ʻole.ʻO ia nā huahana pani o nā paipu kila kahiko a me nā paipu wai inu polychloroprene.Eia nō naʻe, hiki ke hoʻohana wale ʻia ka PE polychloroprene ma ke ʻano he paipu kahawai waho, a hiki ke hoʻohana ʻia nā paipu PE haʻahaʻa haʻahaʻa no ka wai.

He ʻokoʻa ka laulā o ka noi.Nā paipu HDPEHoʻohana nui ʻia no: ʻōnaehana wai wai o ka ʻenekinia municipal, ʻōnaehana wai i loko o nā hale, ʻōnaehana wai kanu waho a me ka ʻōnaehana wai kanu o nā wahi noho a me nā wahi kanu, hoʻoponopono pipeline kahiko, ʻōnaehana wai hoʻomaʻamaʻa ʻenehana, nā paipu wai ʻoihana ma kihapai, irrigation a me na kihapai e ae.He kūpono wale nā ​​paipu PE no ka lawe ʻana i ke kinoea kinoea, ke kinoea maoli a me ke kinoea ʻaila liquefied.ʻO nā paipu PE haʻahaʻa haʻahaʻa he mau paipu.
