kopa ʻaʻa

I ka hopena o 2020, ua hiki i ka 99.959 miliona tons ka nui o ka hana o ka soda caustic, a ua hiki i ka 44.7 miliona tons ka nui o ka hana ʻana o ka soda caustic, e helu ana no 44.7% o ka nui o ka hana o ka honua. hiki.

Ma ka makahiki 2020, ua maʻalahi ka hoʻolaha ʻana o ka mākeke soda caustic o koʻu ʻāina, ka mea nui i ʻekolu mau wahi o North China, Northwest China a me East China.ʻOi aku ka nui o ka nui o ka hana ʻana o ka soda caustic o nā ʻāina ʻekolu ma luna aʻe ma mua o 80% o ka nui o ka mana hana o ka ʻāina.I waena o lākou, ua hoʻomau ka nui o ka māhele o kahi māhele ma North China, a hiki i ka 37.40%.He haʻahaʻa loa ka mana hana o ka soda caustic ma Southwest China, South China a me Northeast China, a he 5% a i ʻole ka liʻiliʻi o ka ʻāpana o ka nui o ka hana ma kēlā me kēia wahi.

I kēia manawa, ua hoʻokūpaʻa nā kulekele ʻoihana e like me ka hoʻoponopono ʻana i ka ʻaoʻao o ka ʻāina i ka ulu ʻana o ka mana hana o ka ʻoihana caustic soda, a i ka manawa like, ua hoʻomau ʻia ka hoʻokūkū hoʻokūkū, a ua hoʻomau ʻia ka hoʻomau ʻana o ka ʻoihana. mahuahua.

PVC

ʻO PVC, a i ʻole polyvinyl chloride, ʻo ia ka mea nui loa ma ka honua a ua hoʻohana nui ʻia.I kēia manawa, ʻelua mau mākeke kūʻai nui no PVC ma koʻu ʻāina: nā huahana paʻakikī a me nā huahana palupalu.ʻO nā huahana paʻakikī ka nui o nā profiles like ʻole, nā paipu, nā papa, nā ʻāpana paʻa a me nā huahana puhi puhi, etc.;ʻO nā huahana palupalu ka nui o nā kiʻiʻoniʻoni, nā uea a me nā kaula, nā ʻili kūlohelohe, nā uhi lole, nā ʻili like ʻole, nā mīkina lima, nā mea pāʻani, nā uhi papahele no nā kumu like ʻole, nā kāmaʻa plastik, a me kekahi mau uhi kūikawā a me nā sealants, etc.

Mai ka manaʻo o ka noi, i nā makahiki i hala iho nei, ua piʻi mau ka noi no ka resin PVC i koʻu ʻāina.I ka makahiki 2019, ua hōʻea ka ʻai ʻana o ka resin PVC ma Kina i 20.27 miliona tons, kahi hoʻonui makahiki o 7.23%.Me nā noi like ʻole o ka polyvinyl chloride resin, ke manaʻo ʻia nei ka hoʻohana ʻana o ka polyvinyl chloride resin i koʻu ʻāina e hiki i 22.109 miliona tons i 2021, a nui ka manaʻo o ka mākeke.

Nānā o ka ʻoihana Chlor-Alkali

ʻO ke ʻano kumu o ke kaulahao ʻoihana ʻo ia ka hoʻohana ʻana i ke ʻano diaphragm a i ʻole ke ʻano membrane ionic e electrolyze i ka wai paʻakai e kiʻi i nā mea chlorine maka, a ma ka manawa like e hana pū ai i ka soda caustic, a hoʻohana ʻia ke kinoea chlorine e like me ka mea maka no PVC. hana ʻana.

Mai ka hiʻohiʻona o ka pōʻai waiwai, ua hoʻopilikia nui ʻia ka ʻoihana chlor-alkali e ke kūlana macroeconomic.Ke hoʻomaikaʻi nei ka macro-economy, hoʻoulu ʻia ka ʻoihana chlor-alkali e ka ʻai a ulu wikiwiki;i ka wā i emi ai ka macro-economy, e lohi ana ka noi no ka ʻoihana chlor-alkali, ʻoiai ʻo ka hopena cyclical kekahi lag., akā ʻo ke ʻano o ka ʻoihana chlor-alkali e kūlike me ka ʻoihana macro.

Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana macro o koʻu ʻāina a me ke kākoʻo koi ikaika mai ka mākeke waiwai, ua hoʻomohala ʻia ke kumu hoʻohālike kākoʻo "PVC + caustic soda" o ka ʻoihana chlor-alkali o koʻu ʻāina i ka nui, a ua loaʻa ka mana hana a me nā huahana. ulu wikiwiki.ua lilo koʻu ʻāina i mea hana nui a me ka mea kūʻai aku i nā huahana chlor-alkali.
