Paipu palaki

Ma ke ʻano he ʻāpana koʻikoʻi o nā mea hana hale 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 hoʻohana haʻahaʻa a me nā pono ʻē aʻe, ʻo ia hoʻi me ka paipu wai UPVC, ka paipu wai UPVC, ka alumini plastic composite pipe, polyethylene (PE) paipu wai 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 pono o ka wai liʻiliʻi liʻiliʻi, ka mālama ʻana i ka ikehu, ka mālama ʻana i nā mea waiwai, ka mālama ʻana i ka ecological, ka hoʻopau kūpono a pēlā aku, a ua lilo i ka ikaika nui o ke kūlanakauhale kūkulu hale paipu pūnaewele 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. 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. Hoʻohālikelike ʻia me ka paipu metala kuʻuna a me ka paipu sima, he māmā ke kaumaha o ka paipu plastik, ʻo ia ka mea maʻamau 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 mālama 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 hoʻololi i nā paipu kila kahiko a me nā paipu hao hao, akā no ka hoʻololi ʻana 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 ʻano 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 o nā paipu kuʻuna i nā manawa kūpono no kēia ʻano. Nui nō hoʻi nā mea hou a me nā ʻenehana e aʻo ʻia, a i ʻole i aʻo ʻia a hoʻāʻo ʻia. He ʻoiaʻiʻo ʻo 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 nui ʻana o nā paipu plastik.
