Hoʻopili ʻia ka Polyvinyl chloride (PVC) Resin, e like me ka inoa e hōʻike nei, ʻo ia ka hoʻohana nui ʻia ʻana o kēia resin ma ke ʻano hoʻopili. Hoʻohana pinepine ka poʻe i kēia ʻano hoʻopili ma ke ʻano he plastisol, he ʻano wai kū hoʻokahi o ka plastic PVC i kona kūlana i hana ʻole ʻia. . Hoʻomākaukau pinepine ʻia nā resins hoʻopili e nā ʻano emulsion a me micro-suspension.
He ʻāpana liʻiliʻi ka nui o ka polyvinyl chloride paste resin, a ua like kona ʻano me ka talc, me ka paʻa ʻole. Hoʻohui ʻia ka polyvinyl chloride paste resin me kahi Plasticizer a laila hoʻoulu ʻia e hana i kahi hoʻokuʻu paʻa, a laila hana ʻia i PVC paste, a i ʻole PVC plastisol, PVC sol, a ma kēia ʻano e hoʻohana ʻia ai nā kānaka e hana i nā huahana hope loa. I ke kaʻina hana o ka hana ʻana i ka paste, hoʻohui ʻia nā mea hoʻopihapiha like ʻole, nā diluents, nā mea hoʻopaʻa wela, nā mea hoʻohua a me nā mea hoʻopaʻa māmā e like me nā pono o nā huahana like ʻole.
ʻO ka hoʻomohala ʻana o ka ʻoihana resin paste PVC e hāʻawi i kahi ʻano wai hou e lilo i huahana polyvinyl chloride ma o ka hoʻomehana wale ʻana. He maʻalahi ke hoʻonohonoho ʻana i kēia ʻano wai, paʻa ka hana, maʻalahi ke kaohi, maʻalahi e hoʻohana, maikaʻi loa i ka hana huahana, maikaʻi i ke kūpaʻa kemika, loaʻa kahi ikaika mechanical, maʻalahi ke kala, a pēlā aku, no laila ua hoʻohana nui ʻia i ka ʻili hana, nā mea pāʻani vinyl, nā hōʻailona kalepa palupalu, ka hana ʻana i nā pepa paia, nā pena a me nā uhi, nā plastics foamed, a pēlā aku.
Waiwai：
ʻO ka resin paste PVC (PVC) kahi māhele nui o nā resins polyvinyl chloride. Ke hoʻohālikelike ʻia me nā resins suspension, he pauka hoʻoheheʻe nui ia. ʻO ka laulā o ka nui o nā ʻāpana he 0.1 ~ 2.0μm maʻamau (ʻo ka hoʻolaha nui o nā ʻāpana o nā resins suspension he 20 ~ 200μm maʻamau.). Ua noiʻi ʻia ka resin paste PVC ma ka hale hana IG Farben ma Kelemania i ka makahiki 1931, a ua hoʻokō ʻia ka hana ʻoihana i ka makahiki 1937.
I loko o ka hapalua kenekulia i hala iho nei, ua ulu wikiwiki ka ʻoihana resin PVC paste honua. ʻOi loa aku i nā makahiki he ʻumi i hala iho nei, ua hōʻike ka hiki ke hana a me ka hoʻopuka i kahi ulu lele, ʻoi aku hoʻi ma Asia. I ka makahiki 2008, ʻo ka huina o ka hiki ke hana o ka resin PVC paste ma kahi o 3.742 miliona tons i kēlā me kēia makahiki, a ʻo ka huina o ka hiki ke hana ma Asia ma kahi o 918,000 tons, e helu ana no 24.5% o ka huina o ka hiki ke hana. ʻO Kina ka ʻāina ulu wikiwiki loa i ka ʻoihana resin PVC paste, me ka hiki ke hana ma kahi o 13.4% o ka huina o ka hiki ke hana honua a ma kahi o 57.6% o ka huina o ka hiki ke hana ma Asia. ʻO ia ka mea hana nui loa ma Asia. I ka makahiki 2008, ʻo ka huina o ka resin PVC paste ma kahi o 3.09 miliona tons, a ʻo ka huina o Kina he 380,000 tons, e helu ana ma kahi o 12.3% o ka huina o ka honua. ʻO ke kolu o ka hiki ke hana a me ka hoʻopuka ma ka honua.
