No ka mea nānā maʻamau, ʻaʻohe ʻokoʻa ma waena o ka paipu PVC a me ka paipu uPVC.ʻO nā paipu plastik ʻelua i hoʻohana nui ʻia i ke kūkulu hale.Ma waho aʻe o nā ʻano like ʻole, hana ʻokoʻa nā ʻano paipu ʻelua a no laila he ʻokoʻa nā waiwai a me nā noi ʻokoʻa ʻē aʻe i ke kūkulu hale a me nā kaʻina hana ʻoihana ʻē aʻe a ʻo ka hapa nui o ka hana hoʻoponopono ʻana i ka paipu plastik i PVC ma mua o uPVC.
Hana ʻia
Hana ʻia ka PVC a me ka uPVC me ka mea like.ʻO ka polyvinylchloride he polymer hiki ke hoʻomehana ʻia a hoʻoheheʻe ʻia e hana i nā pūhui ikaika loa e like me ka paipu.Ma muli o kāna mau waiwai paʻa i ka wā i hoʻokumu ʻia ai, hoʻohui pinepine nā mea hana i nā polymers plasticizing hou i loko o PVC.Hana kēia mau polymers i ka paipu PVC i ʻoi aku ka palupalu a, maʻamau, maʻalahi ka hana ʻana ma mua o ka noho ʻole ʻana.Haʻalele ʻia kēlā mau mea hoʻopalekana i ka wā i hana ʻia ai ka uPVC—pōkole ka inoa no ka polyvinylchloride unplasticized—he ʻaneʻane paʻa loa e like me ka paipu hao.
Ka lawelawe ʻana
No nā kumu hoʻokomo, mālama ʻia ka paipu PVC a me ka uPVC ma ke ʻano like.Hiki ke ʻoki maʻalahi ʻia nā mea ʻelua me ka ʻoki ʻoki ʻoki i nā ʻili a i ʻole nā mea hana mana i hoʻolālā ʻia e ʻoki i ka paipu PVC a ua hui pū ʻia lāua me ka hoʻohana ʻana i nā pūhui gluing ma mua o ke kūʻai ʻana.No ka mea, ʻaʻole i loko o ka paipu uPVC nā polymers plasticizing e hoʻololi iki i ka PVC, pono e ʻoki pono ʻia i ka nui no ka mea ʻaʻole hiki ke hāʻawi.
Nā noi
Hoʻohana ʻia ka paipu PVC ma ke ʻano he pani no ka paipu keleawe a me ka alumini ma luna o ka wai inu ʻole, hoʻololi i ka paipu metala i nā laina ʻōpala, nā ʻōnaehana irrigation a me nā ʻōnaehana holo wai.Ma muli o kona pale ʻana i ka ʻino a me ka hōʻino ʻia mai nā kumu olaola, he huahana paʻa ia e hoʻohana ai i nā ʻōnaehana paipu.Ua ʻoki maʻalahi ʻia a ʻaʻole pono kona mau ami i ke kūʻai ʻana, hoʻopaʻa ʻia me ke kāpili ma kahi o, a hāʻawi i kahi hāʻawi liʻiliʻi ke hāʻawi ʻole ʻia ka nui o nā paipu, no laila ua koho pinepine ʻia ka paipu PVC e nā mea lima ma ke ʻano he mea maʻalahi ke hoʻohana i ka metala. paipu.
ʻAʻole laha loa ka hoʻohana ʻana i ka uPVC i ka paipu ma ʻAmelika, ʻoiai ʻo kona lōʻihi i kōkua iā ia e lilo i mea koho no nā laina paipu paipu, e pani ana i ka paipu hao.Hoʻohana pinepine ʻia i ka hana ʻana i nā ʻōnaehana hoʻoheheʻe o waho e like me ka ua.
ʻO ke ʻano o ka paipu plastik pono e hoʻohana ʻia no ka lawe ʻana i ka wai inu ʻo ia ka paipu cPVC.
