ʻO PVC kahi polymer i hana ʻia e ka polymerization radical manuahi o nā monomers vinyl chloride (VCM) me nā mea hoʻomaka e like me ka peroxide a me nā pūhui azo a i ʻole ma lalo o ka hana o ka māmā a me ka wela.
ʻO PVC ka mea i hoʻopuka nui loa i ka honua o nā plastics maʻamau, ʻo ia kekahi o nā plastics maʻamau ʻelima (PE polyethylene, PP polypropylene, PVC polyvinyl chloride, PS polystyrene, ABS). Hoʻohana nui ʻia ia. , ka ili papahele, ka papahele papahele, ka ili artificial, ka paipu, ka uwea a me ka uwea, ke ki'i pa'i, na omole, na mea ehuehu, na mea sila, na fiber a me na mea e ae.
Ua ʻike ʻia ʻo PVC i ka makahiki 1835 ma United States.Ua hana ʻia ʻo PVC i nā makahiki 1930. Mai ka makahiki 1930, no ka manawa lōʻihi, ua noho ka hana PVC i ka wahi mua ma ka honua.
E like me ka 'okoʻa noi scope, PVC hiki ke maheleia i: maʻamau PVC resin, kiʻekiʻe polymerization degere PVC resin, crosslinked PVC resin.According i polymerization hana, PVC hiki ke maheleia i eha kumu nui waeʻano: hoʻokuʻu PVC, emulsion PVC, bulk PVC, hoʻonā PVC.
ʻO ka polyvinyl chloride ka maikaʻi o ka flame retardant (ʻoi aku ka nui o ke ahi ma mua o 40), ke kūpaʻa kiʻekiʻe (kū'ē i ka waikawa hydrochloric concentrated, 90% sulfuric acid, 60% nitric acid a me 20% sodium hydroxide), ikaika ikaika a me ka uila uila. .
Mai 2016 a 2020, ua piʻi ka hana PVC honua. E like me nā helu a Bloomberg, ʻo ka hana PVC o Kina he 42% o ka hana honua, e pili ana i ka hana PVC honua i manaʻo ʻia he 54.31 miliona tons ma 2020.
I nā makahiki i hala iho nei, ua ulu mau ka hoʻohana ʻana i ka ʻoihana PVC.Ma lalo o ke kūlana ʻaʻole e hoʻonui nui ʻia ka mana hana PVC a me ka nui o ka lawe ʻana mai, ʻoi aku ka nui o ka ulu ʻana o ka ʻikepili o ka ʻai ʻana i ka hopena o ka hoʻonui ʻana i ka koi koʻikoʻi ma hope o ka hoʻomaikaʻi ʻana o ka pilina ma waena o ka lako a me ka noi. ʻO ka ethylene i loko o ka lewa Kina he 889 miliona tons, e hoʻonui ana i ka 1.18 miliona tons a i ʻole 6.66% i hoʻohālikelike ʻia me ka makahiki i hala. Ma ke ʻano holoʻokoʻa, ʻoi aku ka nui o kā mākou hana hana ma mua o ka noi, a ʻaʻole kiʻekiʻe ka nui o ka hoʻohana ʻana i ka mana hana.
Hui Kimia Shin-etsu
Hoʻokumu ʻia ma 1926, ʻo Shin-etsu ke poʻo nui ma Tokyo a loaʻa iā ia nā wahi hana ma 14 mau ʻāina a puni ka honua.
Ua hoʻomohala ʻo Shinetsu Chemical i kāna ʻenehana polymerization nui a me ke kaʻina hana NONSCALE, e alakaʻi ana i ka ʻoihana PVC. I kēia manawa, ma ʻAmelika Hui Pū ʻIa, ʻEulopa a me Iapana ʻekolu mau mākeke nui, e like me nā mea hana PVC nui loa o ka honua me ka mana hana nui, lako paʻa o ke kiʻekiʻe. - nā mea waiwai i ka honua.
Loaʻa iā Shin-yue Chemical kahi mana hana PVC ma kahi o 3.44 miliona tons ma 2020.

2. Occidental Petroleum Corporation
ʻO ka Occidental Petroleum Corporation kahi hui ʻimi ʻaila a me ke kinoea i hoʻokumu ʻia ma Houston me nā hana ma ʻAmelika Hui Pū ʻIa, Middle East, a me ʻAmelika Hema. Ke hana nei ka hui ma o ʻekolu mau māhele: Oil and Gas, Chemical, Midstream and Marketing.
Hoʻopuka nui ka ʻoihana kemika i nā resins polyvinyl chloride (PVC), chlorine a me ka sodium hydroxide (caustic soda) no nā plastics, pharmaceuticals a me nā kemika mālama wai.

3.
ʻO Ineos Group Limited kahi hui pilikino multinational. Hana ʻo Ineos a kūʻai aku i kahi ākea o nā huahana petrochemical, hāʻawi ʻo Ineos i kahi ākea o nā huahana no ka extrusion PVC a me ka hoʻoheheʻe ʻana i ka injection i nā papa he nui, hana noi, automotive, lāʻau lapaʻau, nā mea hana a me nā ʻoihana hoʻopili. puni honua.
ʻO Inovyn kahi hui vinyl chloride resin ma waena o Ineos a me Solvay.E hoʻopaʻa ʻo Inovyn i nā waiwai o Solvay a me Ineos ma ke kaulahao ʻoihana vinyl chloride holoʻokoʻa ma ʻEulopa - polyvinyl chloride (PVC), caustic soda a me ka chlorine derivatives.

4.Westlake Chemistry
ʻO Westlake Corporation, i hoʻokumu ʻia ma 1986 a i hoʻokumu ʻia ma Houston, Texas, he mea hana multinational a me ka mea hoʻolako i nā huahana petrochemical a me nā mea hana.
Ua loaʻa iā Westlake Chemical ka mea hana PVC Kelemania ʻo Vinnolit ma 2014 a me Axiall ma ʻAukake 31, 2016. Ua lilo ka hui hui i ke kolu o ka mea hana chlor-alkali nui loa a me ka lua o ka polyvinyl chloride (PVC) mea hana ma ʻAmelika ʻAmelika.

5. Mitsui Chemical
ʻO Mitsui Chemical kekahi o nā hui kemika nui loa ma Iapana.Hoʻokumu ʻia i ka makahiki 1892, ʻo ia ke keʻena nui ma Tokyo. ʻO ka ʻoihana ka mea nui e hana i nā kumu waiwai petrochemical, synthetic fiber raw material, kemika kumu, resins synthetic, kemika, nā huahana hana, nā kemika maikaʻi, nā laikini a me nā ʻoihana ʻē aʻe.
Ke kūʻai aku nei ʻo Mitsui Chemical i ka resin PVC, plasticizer a me nā mea i hoʻololi ʻia PVC ma Iapana a me nā ʻāina ʻē, e ʻimi ikaika ana i nā mākeke hou, a me ka hoʻonui mau ʻana i ka pāʻoihana.
