PVC ma ke ʻano calcium carbide, Kumukūʻai resin PVC,
ʻO PVC kahi acronym no ka polyvinyl chloride.ʻO ka resin kahi mea i hoʻohana pinepine ʻia i ka hana ʻana i nā plastics a me nā rubbers.ʻO ka resin PVC kahi pauka keʻokeʻo i hoʻohana mau ʻia e hana i nā thermoplastics.He mea synthetic ia i hoʻohana nui ʻia i ka honua i kēia lā.ʻO ka polyvinyl chloride resin he mau hiʻohiʻona koʻikoʻi e like me ka nui o nā mea maka, ka ʻenehana hana makua, ke kumu kūʻai haʻahaʻa, a me ka nui o nā hoʻohana.He mea maʻalahi ka hana a hiki ke hana ʻia e ka hoʻoheheʻe ʻana, laminating, injection molding, extrusion, calendering, blow molding a me nā ʻano hana ʻē aʻe.Me nā waiwai kino a me nā kemika maikaʻi, hoʻohana nui ʻia ia i ka ʻoihana, ke kūkulu ʻana, ka mahiʻai, ke ola o kēlā me kēia lā, ka pahu, ka uila, nā pono lehulehu, a me nā ʻano ʻē aʻe.ʻO nā resins PVC maʻamau he kūʻē kemika kiʻekiʻe.He ikaika loa a kū i ka wai a me ka abrasion.Hiki ke hana ʻia ka polyvinyl chloride resin (PVC) i nā huahana plastik like ʻole.ʻO ka PVC he mea maʻalahi, kūʻaiʻole, a pili i ke kaiapuni.Hiki ke hoʻohana ʻia ʻo Pvc Resin i nā paipu, nā puka makani, nā ʻili, nā ʻili, nā uea, nā kāmaʻa a me nā huahana palupalu maʻamau ʻē aʻe, profiles, fittings, panels, injection, moulding, kāmaʻa, paipu paʻa a me nā mea hoʻonaninani, nā ʻōmole, nā pepa, kalena, ʻo ka hoʻoheheʻe ʻana a me nā mea hoʻoheheʻe, a me nā mea ʻē aʻe.
