Hoʻohana ʻana i nā paipu plastik
Ma ke ʻano he ʻāpana koʻikoʻi o nā mea hana kemika, ʻae ʻia nā paipu plastik e nā mea hoʻohana no kā lākou hana ʻoi aku ka maikaʻi, ka hoʻomaʻemaʻe, ka mālama ʻana i ke kaiapuni, ka ʻai haʻahaʻa a me nā pono ʻē aʻe, ʻo ia hoʻi me ka UPVC paipu wai, UPVC wai lako paipu, alumini plastic composite pipe, polyethylene ( PE) paipu wai, polypropylene PPR paipu wai wela.
ʻO nā paipu palaki nā mea hale kemika i hoʻohui ʻia e ka ʻenehana kiʻekiʻe, a ʻo nā mea hale kemika ka ʻehā o nā ʻano mea kūkulu hale hou ma hope o ke kila, ka lāʻau a me ka sima.Hoʻohana nui ʻia nā paipu plastik i nā kula o ke kūkulu ʻana i ka wai a me ka hoʻoheheʻe ʻana, ka lako wai o ke kūlanakauhale a me ka hoʻoheheʻe ʻana a me nā paipu kinoea ma muli o ko lākou mau pono o ka liʻiliʻi wai liʻiliʻi, mālama ʻana i ka ikehu, mālama waiwai, mālama kaiaola, hoʻopau kūpono a pēlā aku. ʻo ka ikaika nui o ka ʻoihana paipu kūkulu kūlanakauhale i ke kenekulia hou.
Ke hoʻohālikelike ʻia me nā paipu hao kuʻuna, nā paipu kila galvanized, nā paipu sima a me nā paipu ʻē aʻe, ʻo nā paipu plastik nā mea maikaʻi o ka mālama ʻana i ka ikehu a me ka mālama waiwai, ka mālama ʻana i ke kaiapuni, ke kaumaha māmā a me ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion, ka paia i loko me ka ʻole o ka scaling, hana maʻalahi a mālama, ola lawelawe lōʻihi a pēlā aku.Hoʻohana nui ʻia lākou i ke kūkulu ʻana, ka municipal, ʻoihana a me nā māla mahiʻai e like me ke kūkulu ʻana i ka wai a me ka hoʻoheheʻe ʻana, ka wai o ke kūlanakauhale a me ke kua'āina a me ka hoʻoheheʻe ʻana, ke kinoea kūlanakauhale, ka mana a me ka sheath cable optical, ka hoʻoili wai ʻana o ka ʻoihana, ka wai ʻai a me nā mea ʻē aʻe.
Heʻokoʻa ka plastic mai nā mea kahiko.ʻOi aku ka wikiwiki o ka holomua ʻenehana.ʻO ka puka mau ʻana o nā ʻenehana hou, nā mea hou a me nā kaʻina hana hou e ʻoi aku ka maikaʻi o nā paipu plastik i ʻoi aku ka nui o ka hoʻohālikelike ʻia me nā mea kahiko.Ke hoʻohālikelike ʻia me ka paipu metala kuʻuna a me ka paipu sima, he māmā ke kaumaha o ka paipu plastik, ʻo ia hoʻi he 1/6-1/10 wale nō o ka paipu metala.ʻOi aku ka maikaʻi o ka corrosion, ka hopena a me ka ikaika tensile.ʻOi aku ka maʻalahi o ka ʻili o loko o ka paipu plastik ma mua o ka paipu hao, me ka liʻiliʻi friction coefficient a me ke kūpaʻa wai.Hiki iā ia ke hōʻemi i ka hoʻohana ʻana i ka ikehu wai ma mua o 5%.Loaʻa iā ia ka mālama ʻana i ka ikehu piha, a ua hoʻemi ʻia ka hoʻohana ʻana i ka ikehu e 75%.He mea maʻalahi ka lawe ʻana, maʻalahi e hoʻokomo, a ʻo kona ola lawelawe a hiki i 30-50 mau makahiki.Ua ulu wikiwiki nā paipu Polyethylene i ka honua, a ua loaʻa i nā ʻāina i kūkulu ʻia kahi pōmaikaʻi loa i ka hoʻohana ʻana i nā paipu polyethylene ma ke kahua o ka wai a me ke kinoea.ʻAʻole hoʻohana nui ʻia nā paipu polyethylene e pani i nā paipu kila kahiko a me nā paipu hao hao, akā e hoʻololi pū i nā paipu PVC.Aia ke kumu i ka hana ʻenehana o nā paipu polyethylene.Ma kekahiʻaoʻao, ua holomua ka mea waiwai.Ma o ka hoʻomaikaʻi ʻana i ke kaʻina hana polyethylene polymerization, ua aneane pālua ka ikaika o ka polyethylene pipe kūikawā.Ma ka ʻaoʻao ʻē aʻe, aia nā hanana hou i ka ʻenehana noiʻi, e like me ka ʻenehana o ka hoʻomoe ʻana i nā paipu polyethylene ma ke ala hoʻoheheʻe kuhikuhi me ka ʻole o ka ʻeli ʻana i nā auwaha paipu, e hāʻawi ana i ka pāʻani piha i nā pono o nā paipu polyethylene, no laila ʻaʻohe hoʻokūkū hoʻokūkū i nā manawa. kūpono no kēia ʻano hana.Nui nō hoʻi nā mea a me nā ʻenehana hou e aʻo ʻia, a i ʻole i aʻo ʻia a hoʻāʻo ʻia.He mea maopopo ka holomua ʻenehana o nā paipu plastik i nā makahiki he 10 e hiki mai ana e hāpai i ka hoʻomohala wikiwiki a me ka hoʻohana ākea ʻana o nā paipu plastik.
