He aha ka Polyvinyl chloride (PVC) paste Resin?

ʻO ka Polyvinyl chloride (PVC) paʻi Resin, e like me ka inoa i hōʻike ʻia, ʻo ia ka hoʻohana nui ʻia o kēia resin ma ke ʻano paʻi.Hoʻohana pinepine ka poʻe i kēia ʻano paʻi ma ke ʻano he plastisol, kahi ʻano wai kū hoʻokahi o ka plastic PVC i kona kūlana ʻaʻole i hana ʻia..Hoʻomākaukau pinepine ʻia nā resins paste e ka emulsion a me nā ʻano micro-suspension.

ʻO ka polyvinyl chloride paste resin ka nui o ka ʻāpana, a ua like kona ʻano me ka talc, me ka ʻole.Hoʻopili ʻia ka resin polyvinyl chloride paste 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 paʻi ʻana, hoʻohui ʻia nā mea hoʻopihapiha like ʻole, diluents, heat stabilizers, foaming agents a me nā stabilizer māmā e like me nā pono o nā huahana like ʻole.

Hāʻawi ka hoʻomohala ʻana i ka ʻoihana resin paʻi PVC i kahi ʻano wai wai hou e lilo i huahana polyvinyl chloride wale nō ma ka hoʻomehana.He mea maʻalahi kēia ʻano wai wai e hoʻonohonoho, kūpaʻa i ka hana, maʻalahi e hoʻokele, maʻalahi e hoʻohana, maikaʻi loa i ka hana huahana, maikaʻi i ka paʻa kemika, loaʻa kekahi ikaika mechanical, maʻalahi ke kala, a pēlā aku, no laila ua hoʻohana nui ʻia. i ka ʻili hana, nā mea pāʻani vinyl, nā hōʻailona maʻemaʻe, Ka hana ʻana i nā kiʻi paʻi kiʻi, nā pena a me nā uhi, nā plastics foamed, etc.

Waiwai:

ʻO ka PVC paste resin (PVC) kahi ʻāpana nui o nā resins polyvinyl chloride.Ke hoʻohālikelike ʻia me nā resins suspension, he pauka hoʻopuehu loa ia.He 0.1 ~ 2.0μm ka nui o ka nui o ka nui (ʻo 20 ~ 200μm ka nui o nā resins hoʻomaha).Ua noiʻi ʻia ʻo PVC paste resin ma ka hale hana IG Farben ma Kelemānia i ka makahiki 1931, a ua hoʻokō ʻia ka hana ʻoihana i ka makahiki 1937.

I ka hapalua o ka makahiki i hala iho nei, ua ulu wikiwiki ka ʻoihana Pvc Resin honua.ʻOi aku i nā makahiki he ʻumi i hala iho nei, ua hōʻike ka mana hana a me ka hoʻopuka ʻana i kahi ulu lele, ʻoi aku ma Asia.I ka makahiki 2008, ʻo ka nui o ka nui o ka hana ʻana o ka resin PVC i hoʻopaʻa ʻia ma kahi o 3.742 miliona tons i kēlā me kēia makahiki, a ʻo ka nui o ka mana hana ma Asia ma kahi o 918,000 tons, e helu ana no 24.5% o ka nui o ka mana hana.ʻO Kina ka ʻāina ulu wikiwiki loa i ka ʻoihana paʻi PVC resin, me ka mana hana e helu ana ma kahi o 13.4% o ka nui o ka mana hana honua a ma kahi o 57.6% o ka nui o ka mana hana ma Asia.ʻO ia ka mea hana nui loa ma Asia.I ka makahiki 2008, he 3.09 miliona tons ka puka honua o ka resin PVC, a he 380,000 tons ko Kina, e helu ana ma kahi o 12.3% o ka huina o ka honua.ʻO ka mana hana a me ka hoʻopuka ʻana i ke kolu o ka honua.
