一、 Nā ʻano like ʻole
1.HDPE: High Density Polyethylene ("HDPE" no ka pōkole), i ʻike ʻia ʻo Polyethylene haʻahaʻa haʻahaʻa, he ʻano translucent me ka crystallinity kiʻekiʻe a me nā ʻaoʻao non-polar i kekahi ʻano.He resin thermoplastic non-polar me ka crystallinity kiʻekiʻe.
2. MPVE: ʻO ka paipu hoʻoheheʻe ʻia ʻo MPVE pālua ʻelua he paipu hoʻoheheʻe kūloko hou i paionia a hoʻomohala ʻia e Kangtai Plastic Technology Group ma Kina.Hana ʻia me ka polyvinyl chloride a me ka polyethylene polymerization a loaʻa iā ia nā kuleana waiwai naʻauao kūʻokoʻa.
二、Nā hana likeʻole
1.HDPE: maikaʻi ke kū'ē wela a me ke anuanu, ke kūpaʻa kemika maikaʻi, akā he kiʻekiʻe ka rigidity a me ka paʻakikī, ka ikaika mechanical maikaʻi.He maikaʻi nō hoʻi nā waiwai dielectric.ʻOi aku ka paʻakikī, ka ikaika tensile a me nā mea kolo o ka polyethylene haʻahaʻa haʻahaʻa ma mua o ka polyethylene haʻahaʻa haʻahaʻa.ʻO ke kūpaʻa ʻaʻahu maikaʻi, ka insulation uila, ka paʻakikī a me ke kūpaʻa anu.ʻAʻole ikaika e like me HDPE.
2. MPVE: ke hoʻohālikelike ʻia me ka HDPE pālua-pā ʻia ka paipu corrugated, ʻoi aku ka maikaʻi o ka hana holoʻokoʻa ma mua o nā huahana paipu paʻa paʻa pālua i kēia manawa, he mea koʻikoʻi loa ia no ka hoʻomohala ʻana i ka paipu paʻa pālua.A hoʻokō i ka 20-25% mālama waiwai, 10-25% ho'ēmi kumu.He kūpono no ka ua paipu wai a me ka haʻahaʻa haʻahaʻa kuaʻāina irrigation paipu.
三、Manaʻo like ʻole
1.HDPE: He kū'ē maikaʻi loa ka HDPE i ka hapa nui o nā kemika home a me nā ʻoihana.
2. MPVE: Me ka paʻa wai ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o ka maikaʻi a me ka haʻahaʻa haʻahaʻa o ke kumukūʻai holoʻokoʻa, hiki ke hoʻololi i nā bellows HDPE pālua.
