Ka hoohana ana i ka paipu PE

1. Paipu mining PE
Ma waena o nā plastic 'enekinia a pau, ʻo HDPE ka mea kiʻekiʻe loa o ka pale lole a ʻo ia ka mea i ʻike ʻia.ʻOi aku ke kiʻekiʻe o ke kaumaha o ka molekala, ʻoi aku ka ʻoi aku o ka ʻaʻahu o ka mea, 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).Ma lalo o nā kūlana o ka corrosion ikaika a me ka 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%.He maikaʻi nā mea pale ahi a me nā waiwai antistatic a hoʻokō i nā koi maʻamau.ʻO ke ola lawelawe downhole ma luna o 20 mau makahiki, me nā pōmaikaʻi waiwai kupaianaha, ka hopena o ka hopena, ka pale ʻana a me ke kūʻē pālua.

2. ʻO ka paipu wai wai PE
Ua kapa ʻia ka paipu PE no ka hoʻokuʻu ʻana i ka wai wai kiʻekiʻe kiʻekiʻe polyethylene paipu, ʻo ia ka HDPE ma ka ʻōlelo Pelekania.Hoʻohana pinepine ʻia kēia ʻano paipu ma ke ʻano he koho mua no ka ʻenekinia municipal, i hoʻohana nui ʻia i ka ʻoihana mālama wai.Ma muli o kona pale ʻana i ka ʻaʻahu, ka pale ʻana i ka waika, ka pale ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me nā ʻano ʻē aʻe, ua hoʻololi mālie ʻo ia i ke kūlana o nā paipu kuʻuna e like me nā paipu kila a me nā paipu sima ma ka mākeke, ʻoiai no ka māmā o kēia paipu i ke kaumaha. a maʻalahi e hoʻouka a neʻe, a ʻo ia ka koho mua o nā mea hou.Pono nā mea hoʻohana e nānā pono i nā mea ma lalo i ke koho ʻana i nā paipu i hana ʻia i kēia mea: 1. E nānā pono i ke koho ʻana i nā mea maka no nā paipu plastik.He mau kaukani o nā māka o ka polyethylene maka waiwai, a aia nā mea maka e like me ka haʻahaʻa he mau tausani yuan no ke tona ma ka mākeke.ʻAʻole hiki ke kūkulu ʻia nā huahana i hana ʻia e kēia maka, inā ʻaʻole, nui nā poho hana hou.2. ʻO ke koho ʻana i nā mea hana pipeline e pili ana i nā mea hana maʻamau a ʻoihana.3. Ke koho ʻana e kūʻai i nā paipu PE, e nānā i nā mea hana ma ia wahi e ʻike inā loaʻa iā lākou ka mana hana.

3. PE paipu wai
ʻO nā paipu PE no ka hoʻolako wai nā huahana pani o nā paipu kila kahiko a me nā paipu wai inu PVC.
Pono ka paipu wai e hoʻokau i kekahi kaomi, a ʻo ka PE resin me ke kaumaha molekala kiʻekiʻe a me nā waiwai mechanical maikaʻi, e like me ka HDPE resin, ke koho pinepine ʻia.ʻO ka resin LDPE he haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa, paʻakikī paʻakikī, maikaʻi ʻole ke ʻano i ka wā o ka hana ʻana a me ka pilina paʻakikī, no laila ʻaʻole kūpono ia e like me ke ʻano o ka paipu wai.Eia nō naʻe, ma muli o kona ʻano maʻemaʻe kiʻekiʻe, ua lilo ʻo PE, ʻoi aku ka HDPE resin, i mea maʻamau no ka hana ʻana i nā paipu wai inu.ʻO ka resin HDPE he haʻahaʻa hoʻoheheʻe haʻahaʻa, ka wai maikaʻi a me ka hana maʻalahi, no laila he nui nā koho o kāna melt index, maʻamau ka MI ma waena o 0.3-3g / 10min.
