ʻO ka Polyvinyl Chloride (PVC) kahi polymer thermoplastic synthesized a ʻo ke kolu o ka mea i hana nui ʻia i ka plastic synthetic.Ua hoʻokomo mua ʻia kēia mea i ka mākeke i ka makahiki 1872, a he mōʻaukala lōʻihi o ka kūleʻa i nā noi he nui.Hōʻike ʻia ʻo PVC ma kahi ākea, me ka ʻoihana kāmaʻa, ʻoihana kelepona, ʻoihana kūkulu hale, ʻoihana mālama olakino, nā hōʻailona, a me nā lole.
ʻO nā ʻano maʻamau ʻelua o ka PVC he paʻa paʻa ʻole a me ka plasticized maʻalahi.ʻO ke ʻano paʻa he polymer unplasticized (RPVC a i ʻole uPVC).Hoʻopuka pinepine ʻia ʻo PVC paʻa e like me ka paipu a i ʻole ka paipu no ka mahiʻai a me ke kūkulu ʻana.Hoʻohana pinepine ʻia ke ʻano maʻalahi ma ke ʻano he uhi no nā uea uila a me nā noi ʻē aʻe kahi e pono ai kahi paipu plastik palupalu.
He aha nā ʻano o ka Polyvinyl Chloride (PVC)?
ʻO PVC kahi mea kaulana a maʻalahi me nā hiʻohiʻona maikaʻi.
