1. Pipe hoʻouku PE
Ma waena o nā plastics ʻenekini, aia i ka HDPE ke kūpaʻa lole kiʻekiʻe loa a ʻo ia ka mea i ʻike nui ʻia. ʻO ke kiʻekiʻe o ke kaona mole, ʻoi aku ka paʻa o ka mea, ʻoi aku i ka nui o nā mea hao (e like me ke kalapona kila, mea kila, keleawe, a pēlā aku.). Ma lalo o nā kūlana o ka ʻaʻai ikaika a me nā lole kiʻekiʻe, ʻo ke ola lawelawe he 4-6 mau manawa o ka paipu kila a me 9 mau manawa o ka polyethylene maʻamau; A hoʻomaikaʻi ʻia ka maikaʻi o ka lawe ʻana e 20%. ʻO nā pale retardant a me nā antistatic maikaʻi he maikaʻi a hoʻokō i nā koina maʻamau. ʻO ke ola o ka downhole ma luna o 20 mau makahiki, me nā pōmaikaʻi hoʻokupu kupaianaha, ka hopena hopena, ka pale ʻaule a me ka pale pālua.
2. Paipu humuhumu PE
ʻO ka paipu PE no ka hoʻolei wai hoʻowahāwahā kahi i kapa ʻia he paipu polyethylene kiʻekiʻe kiʻekiʻe, ʻo ia hoʻi HDPE i ka ʻōlelo Pelekania. Hoʻohana pinepine ʻia kēia ʻano paipu ma ke ʻano he koho mua loa no ka ʻenekini kulanakauhale, hoʻohana nui ʻia i ka ʻoihana hoʻomaʻemaʻe wai. Ma muli o ke kūpaʻa o ka ʻaʻa, ke kūpaʻa waikawa, ke kūpaʻa ʻaʻa, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me nā ʻano ʻē aʻe, ua hoʻololi mālie ia i ke kūlana o nā paipu kuʻuna e like me nā paipu kila a me nā paipu sima i ka mākeke, keu hoʻi no ka māmā o kēia paipu i ke kaupaona a maʻalahi e hoʻouka a neʻe, a ʻo ia ke koho mua o nā mea hou. Pono nā mea hoʻohana e nānā pono i nā helu aʻe i ke koho ʻana i nā paipu i hana ʻia i kēia mea: 1. E nānā pono i ke koho ʻana o nā mea maka no nā paipu plastic. Aia he mau kaukani mau helu o nā mea maka he polyethylene, a aia kekahi mau mea waiwai ma lalo o kahi mau kaukani yuan ma ke ton i ka mākeke. ʻAʻole hiki ke kūkulu ʻia nā huahana i hana ʻia e kēia mea maka, a i ʻole, nui nā poho hou. 2. E pili ana ke koho ʻana o nā mea hana paipu i nā mea hana hana a me ka ʻoihana. 3. Ke koho ʻana e kūʻai i nā paipu PE, e nānā i nā mea hana ma kahi e ʻike ai inā he mana hana kā lākou.
3. Paipu lako wai PE
ʻO nā paipu PE no ka lako wai nā huahana pani o nā paipu kila kuʻuna a me nā paipu wai inu PVC.
Pono ka paipu lako wai e halihali i kekahi kaomi, a me ke kēpau PE me ke kaupaona kiʻekiʻena mika a me nā pono mīkini maikaʻi, e like me ka HDPE resin, e koho maʻamau. LDPE kēpau i haʻahaʻa tenile ikaika, ilihune puʻe ia'ku, ilihune rigidity, ilihune dimensional kumupaʻa ma mōlina a me ka paʻakikī pilina, no laila ia mea ʻaʻole kūpono e like me ka mea o ka wai lako puʻe paipu. Eia nō naʻe, ma muli o kāna papa kuhikuhi hoʻomaʻemaʻe kiʻekiʻe, ʻo PE, ʻo ia hoʻi ʻo HDPE resin, ua lilo i mea maʻamau no ka hana ʻana i nā paipu wai inu. He haʻahaʻa viscosity hoʻoheheʻe HDPE resin, fluidity maikaʻi a me ka hana maʻalahi, no laila he nui nā koho a kāna index hoʻoheheʻe, ʻo ka maʻamau ma waena o 0.3-3g / 10min.
