Ka helu o ke kaomi: 0.15Mpa, 0.25Mpa
Hiki ke kūpono: Pili no ka hāʻawi haʻahaʻa haʻahaʻa o ka wai irrigation.

Ke ano pili: Hoʻohana nui ʻia ka pilina pili.
Ua hoʻokumu ʻia ʻo Dayu Water Saving Group Co., Ltd. ma 1999. He ʻoihana ʻenehana kiʻekiʻe ia e pili ana i ka Chinese Academy of Water Science, ka Science and Technology Promotion Center o ke Kuhina Waiwai, ka Chinese Academy of Science, ka Chinese Academy of Engineering a me nā keʻena noiʻi ʻepekema ʻē aʻe.Kau ʻia ma ka Growth Enterprise Market.Kānāwai waiwai: 300021. Ua hoʻokumu ʻia ka hui no 20 mau makahiki a ua hoʻomau mau a hoʻolaʻa iā ia iho i ka hoʻonā a me ka lawelawe ʻana o ka mahiʻai, nā wahi kuaʻāina a me nā kumu wai.Ua hoʻomohala ʻia i loko o kahi hōʻiliʻili o ka mālama wai mahiʻai, ka lako wai o ke kūlanakauhale a me ke kua'āina, ka mālama ʻana i ka wai, nā hana wai akamai, ka pili ʻana o ka ʻōnaehana wai, ka hoʻokele kaiaola wai a me ka hoʻihoʻi ʻana a me nā māla ʻē aʻe.He mea hoʻolako ʻōnaehana ʻoihana no ke kaulahao ʻoihana holoʻokoʻa e hoʻohui ana i ka hoʻolālā papahana, hoʻolālā, hoʻopukapuka, kūkulu, hana, hoʻokele a me nā lawelawe mālama.ʻO ia ka mua o ka ʻoihana ma ke kahua o ka mālama wai mahiʻai ma Kina a he alakaʻi honua.
ʻO ka polyethylene kiʻekiʻe, HDPE kahi polyolefin thermoplastic i hana ʻia e ka copolymerization o ka ethylene.ʻOiai ua hoʻokuʻu ʻia ʻo HDPE i ka makahiki 1956, ʻaʻole i hiki i kēia plastic i kahi pae oʻo.Ke hoʻomohala mau nei kēia mea hana maʻamau i kāna mau hoʻohana hou a me nā mākeke.
Nā hiʻohiʻona nui
ʻO nā hiʻohiʻona kūʻokoʻa o nā māka like ʻole o ka HDPE ʻo ia ka hui kūpono o nā ʻano hoʻololi kumu ʻehā: density, paona molekala, hāʻawi kaumaha molecular a me nā mea hoʻohui.Hoʻohana ʻia nā catalysts e hana i nā polymers maʻamau me nā waiwai kūikawā.ʻO ka hui pū ʻana o kēia mau mea hoʻololi e hana i nā māka HDPE no nā kumu like ʻole;ka loaʻa ʻana o ke kaulike maikaʻi loa i ka hana.
Hana huahana
ʻO ka polyethylene kiʻekiʻe he mea ʻawaʻawa ʻole, ʻono ʻole, a ʻaʻala ʻole nā mea keʻokeʻo me kahi helu heheʻe ma kahi o 130°C a me kahi mānoanoa pili o 0.941 a 0.960.Loaʻa iā ia ke kūpaʻa wela maikaʻi a me ke anuanu, ke kūpaʻa kemika maikaʻi, ka rigidity kiʻekiʻe a me ka paʻakikī, a me ka ikaika mechanical maikaʻi.He maikaʻi nō hoʻi nā waiwai dielectric a me ke koʻikoʻi kaiapuni.
Packaging, mālama a me ka lawe ʻana
E mālama i ke ahi a me ka wela i ka wā e mālama ai.Pono e maloʻo a maʻemaʻe ka hale waihona.Ua kapu loa ia e hui me na mea haumia, ka la a me ka ua.Pono e mālama ʻia ka lawe ʻana i loko o nā kaʻa maʻemaʻe, maloʻo, uhi ʻia a i ʻole nā hale kaʻa, a ʻaʻohe mea ʻoi e like me nā kui hao.ʻAʻole pāpā ʻia ka lawe ʻana i hui pū me nā hydrocarbons aromatic flammable, halogenated hydrocarbons a me nā mea hoʻoheheʻe organik ʻē aʻe.
hana hou a hoʻohana hou
ʻO HDPE ka ʻāpana wikiwiki loa o ka mākeke recycling plastic.ʻO kēia ma muli o kāna hana maʻalahi, nā hiʻohiʻona hoʻohaʻahaʻa liʻiliʻi a me kāna helu nui o nā noi no nā kumu hoʻopili.ʻO ka hana hou ʻana, ʻo ia ka hana hou ʻana i 25% o nā mea hana hou, e like me nā mea hoʻohana hou ʻia (PCR), me ka HDPE maʻemaʻe e hana i nā ʻōmole i pili ʻole me ka meaʻai.
ʻO nā paipu PE no ka hoʻolako wai nā huahana pani o nā paipu kila kahiko a me nā paipu wai inu polyvinyl chloride (PVC).
