Ua hōʻea ka piʻi ʻana i 71.14%, a ua "piha i ka mana ahi" nā wā e hiki mai ana o PVC

Mai ka wā i kāohi ʻia ai ke ahulau i kēia makahiki a ua hoʻomaka ka hoʻokele waiwai o koʻu ʻāina e hoʻōla, ua hoʻomaka ka piʻi ʻana o nā kumukūʻai mua o ka polyvinyl chloride (ma hope aku i kapa ʻia ʻo PVC) mai ke kumu kūʻai haʻahaʻa loa ma ʻApelila 1: 4955. I waena o lākou, ʻo ke kumukūʻai kiʻekiʻe loa o nā kumukūʻai mua o PVC ʻehā mau makahiki i hala aku nei he 8205. Wahi a ka ʻikepili hou loa, ua piʻi hou ke kumukūʻai pani o PVC a ua haki i ka moʻolelo kiʻekiʻe: 8480! Mai 4955 i ʻApelila a i 8480 i nā lā ʻelua mua, ua hiki ka piʻi ʻana i 71.14%! Inā paha mai ka nui o ka lako a me ke koi, a i ʻole ka hoʻomaikaʻi ʻana o ka hoʻolālā ʻoihana a me ka mana o nā mea kau, hiki ke wehewehe ʻia nā kumukūʻai mua o PVC o kēia makahiki he "ahi piha"!

He nui loa ke ao nei, ʻo ka ʻoiaʻiʻo, he mea pono ke ola
He pauka keʻokeʻo ʻaʻohe ʻawahia a ʻala ʻole ka Polyvinyl Chloride (PVC) me ke kūpaʻa kemika kiʻekiʻe a me ka plasticity maikaʻi.
ʻO ka Polyvinyl chloride ka mea resin synthetic nui loa ma koʻu ʻāina a ʻo ka lua o ka nui loa ma ka honua. Hoʻohana nui ʻia ia e hana i nā ʻano hana like ʻole, nā ʻano hana like ʻole, nā mea hoʻopili paipu, nā papa, nā pepa, nā ʻūpā uwea, nā paipu paʻakikī a palupalu paha, nā lako hoʻoili koko a me nā kiʻiʻoniʻoni, a pēlā aku.
He ʻāina hana nui koʻu ʻāina a he mea kūʻai aku i ka polyvinyl chloride. Hoʻopilikia ʻia ke kumukūʻai o ka polyvinyl chloride e nā kumu he nui. Hoʻololi pinepine ke kumukūʻai a nui ka pae o ka loli. Ke kū nei nā ʻoihana hana PVC, kālepa a me ka hana ʻana i nā pilikia ʻoihana nui a komo i nā ʻano like ʻole o ka polyvinyl chloride i ka wā e hiki mai ana. He ikaika loa ke koi no ka mālama ʻana i ka waiwai.
ʻO Polyvinyl chloride (PVC) ka hana nui loa o ka honua o nā plastics no nā kumu maʻamau, a ua hoʻohana nui ʻia. Hoʻohana nui ʻia ia i nā mea kūkulu hale, nā huahana ʻoihana, nā mea pono o kēlā me kēia lā, ka ʻili papahele, nā tile papahele, ka ʻili hana, nā paipu, nā uea a me nā kaula, nā kiʻi ʻōwili, nā ʻōmole, nā mea hoʻohua, nā mea sila, nā olonā, a pēlā aku.
I ka makahiki 2019, ua hoʻomau ka ulu ʻana o ka hana ʻana o ka polyvinyl chloride (PVC), a ua hōʻea ka nui o ka ulu ʻana i kona kiʻekiʻe i nā makahiki ʻelima i hala. Mālama ka pae hana holoʻokoʻa o ka PVC i kahi ʻano piʻi mau. Wahi a nā helu helu mai ka China Chlor-Alkali Industry Association,Ka hana ʻana o PVC ma Kinaua hōʻea i 18.74 miliona tons i ka makahiki 2019, he piʻi makahiki-ma-makahiki o 7.31%.
ʻO ka nui o ka hana hana PVC o Kina e kau nui ʻia ma ka ʻāpana ʻākau

1. Ka hoʻolaha ʻāpana o ka mana hana PVC o koʻu ʻāina:
Ma ke ʻano o nā ʻāpana, ʻo ka nui o ka hiki ke hana PVC o koʻu ʻāina e kau nui ʻia ma ka ʻāpana ʻākau. ʻO ka ʻāina ʻo Shandong ka 13% o ka hiki ke hana PVC aupuni, ʻo ka ʻāina ʻo Inner Mongolia he 10% hoʻi, a ʻo nā ʻāina ʻē aʻe o ka ʻākau: ʻo Henan, Tianjin, a me Xinjiang he 9%, 8%, a me 7%. ʻO nā ʻāina ʻoihana i hoʻomohala ʻia ma ka Hikina o Kina e like me Jiangsu a me Zhejiang he 6% a me 4% wale nō, ʻo ia hoʻi he 10% wale nō o ka hiki ke hana PVC aupuni.

2. ka hana PVC a koʻu ʻāina i nā makahiki i hala iho nei:
I nā makahiki i hala iho nei, ʻo KinaHana ʻana i ka PVCua piʻi aʻe i kēlā me kēia makahiki, a ua hoʻonui nui ʻia kona hiki ke hoʻolako. Ke piʻi nei ke ʻano holoʻokoʻa. ʻAʻole hiki ke hoʻokaʻawale ʻia ke kumu ma hope o ia mea mai ka piʻi nui ʻana o ka hoʻohana ʻana o PVC. I kēia manawa, ʻelua mau mākeke kūʻai nui o ka PVC o koʻu ʻāina: nā huahana paʻakikī a me nā huahana palupalu. ʻO nā huahana paʻakikī nā ʻano like ʻole, nā paipu, nā papa, nā pepa paʻakikī a me nā huahana i hoʻoheheʻe ʻia, a pēlā aku; ʻo nā huahana palupalu nā kiʻiʻoniʻoni, nā uea a me nā kaula, ka ʻili hana, nā uhi lole, nā hose like ʻole, nā mīkina lima, nā mea pāʻani, a me nā uhi papahele no nā kumu like ʻole. Nā mea hana, nā kāmaʻa plastik, a me kekahi mau uhi kūikawā a me nā mea hoʻopaʻa. Mai ka manaʻo o ka hoʻonohonoho hoʻohana o PVC, ʻo ka hoʻohana ʻana o "nā mea hoʻohui paipu a me nā paipu"ua helu ʻia he 42%, ʻo ia ka wahi hoʻohana nui o ka PVC; ukali ʻia e "nā kiʻiʻoniʻoni palupalu a me nā pepa", e helu ana ma kahi o 16%.
