paipu kinoea PE a mePaipu wai wai PEpili iPaipu PE.Ua kapa ʻia ʻo PE he polyethylene.I ka honua, ua māhele ʻia nā paipu polyethylene i ʻelima mau māka: PE32, PE40, PE63, PE80 a me PE100.ʻO nā mea i hoʻohana ʻia no nā paipu wai wai polyethylene a me nā paipu kinoea polyethylene he PE80 a me PE100, he paʻakikī ke hoʻohana, akā lawe pū kekahi i nā pōʻino huna i ka hoʻohana ʻana i nā paipu PE.
No laila, ua hana ka National Bureau of Standards i nā hoʻololi he nui i ka GB/T13663-2000 maʻamau hou, e kuhikuhi ana i nā māka like ʻole o PE80 a me PE100 o ka pipeline wai e pili ana i nā ikaika ikaika ʻē aʻe, e kāpae ana i ka hana ikaika tensile i ka maʻamau kahiko, a me ka hoʻonui ʻana i ka elongation i ka wā hoʻomaha.(ʻOi aku ma mua o 350%), e hoʻokūpaʻa ana i ka paʻakikī kumu.
Hoʻokumu nui ʻia ka hana home o kēia laina hana ma ka PE100 raw material.ʻO kēia ma muli o ka holomua ʻenehana i nā makahiki i hala iho nei.ʻO ke kumu kūʻai kumu waiwai o PE100 ua aneane like me ka PE80.Eia nō naʻe, ma ke ʻano o ka hana, ʻoi aku ka maikaʻi o ka PE100 ma mua o ka PE80 maka.Eia kekahi, ua hoʻomaikaʻi mau ʻia nā paipu wai wai PE a me nā mea laina laina extrusion paipu kinoea PE, a ua hōʻea nā paipu PE i ka pae honua mua.
