ʻO ka Polyvinyl chloride, i kapa ʻia ʻo PVC (Polyvinyl Chloride) ma ka ʻōlelo Pelekania, he VINYL Chloride Monomer (VCM) i hana ʻia e nā peroxides, nā pūhui nitride, etc. a i ʻole ma lalo o ka hana o ka māmā a me ka wela.Polymerized polymer.

ʻIkepili o ke kaulahao ʻoihana: Nā noi ākea i lalo
ʻO ka ʻoihana PVC ka ʻoihana kumu kumu ma muli o ka paʻakai maka, coke a me nā pōhaku uila.Nui nā ʻano o nā huahana PVC a me ka nui o ka pilina.Ua hōʻea kāna mau huahana i lalo i nā tausani o nā ʻano like ʻole a loaʻa ka waiwai hoʻonui waiwai kiʻekiʻe.Hoʻohana nui ʻia ia i nā ʻoihana e like me nā kaula, nā mea pāʻani, nā hoses, nā kiʻiʻoniʻoni, a me nā huahana olakino.Loaʻa iā ia ka hoʻokele waiwai o koʻu ʻāina.E kiʻi i kahi kūlana pivotal.

Ua noho mau ka ʻoihana PVC o Kina i kahi kūlana koʻikoʻi ma ka mākeke honua, me nā waiwai waiwai a me ka ikaika waiwai.Ke ulu nei ka hoʻomohala ʻana o ka ʻoihana PVC o Kina i kahi wikiwiki weliweli, i lawe mai i ke kākoʻo nui i ka hoʻokele waiwai o Kina.

Wahi a ka nānā ʻana i ke kūlana o ka mākeke a me ke kuhikuhi ʻana o ka ʻoihana PVC o Kina i ka makahiki 2023-2029 i hoʻokuʻu ʻia e ka mākeke noiʻi pūnaewele pūnaewele, ua ulu ka nui o ka mākeke o ka ʻoihana PVC o Kina mai 160 biliona yuan i 2017 a i 210 biliona yuan ma 2020 ma i nā makahiki ʻelima i hala, he 31%.Ma hope o kēia ulu holoʻokoʻa ke ʻano o ka hoʻomohala ʻana o ka ʻoihana PVC o Kina a me ka hoʻomau mau ʻana o ka noi mākeke.

Ke hoʻomau nei ka ulu ʻana o ka ʻoihana PVC o Kina i ka ulu ʻana o ka nui o ka ʻoihana a me ka māhele mākeke.ʻO ka mea mua, i alakaʻiʻia e nāʻoihana hana a me nāʻoihana hana, e hoʻomau ka hoʻohanaʻana i nā huahana PVC, e hoʻoikaika i ka uluʻana o kaʻoihana.ʻO ka lua, me ka piʻi ʻana o ka makemake o nā mea kūʻai aku, e piʻi aʻe ke kumukūʻai o nā huahana PVC, i mea e hoʻonui hou ai ka mākeke o ka ʻoihana PVC.ʻO ka hope, i kēia manawa, ua hāʻawi pū ke aupuni i ke kākoʻo ikaika i ka ʻoihana e pili ana i ke kulekele a me ke kākoʻo kālā, e lawe mai i nā mea hōʻoia hou i ka hoʻomohala ʻana i ka ʻoihana.

Ma keʻano laulā, e hōʻike ana ka nui o ka mākeke a me ka hoʻomohala ʻana i ka wā e hiki mai ana o ka ʻoihana PVC o Kina i ka ulu ikaika ʻana, e lawe mai ana i nā pono waiwai a me nā pono pilikanaka i ka hoʻomohala waiwai o Kina.
