I, market review
ʻO PVC(6402, 10.00, 0.16%) ʻaelike nui i ka lā 30 o Kekemapa i pani ʻia ma 6263 yuan/ton, hoʻokahi mahina i 312 yuan/ton (5.24%).
Ke nānā nei i hope i ka mahina ʻo Dekemaba a pau, i ka hapa mua o ka mahina, ua hōʻike ʻia nā ʻaelike nui i ka piʻi ʻana ma muli o ka deregulation o ke kulekele maʻi ahulau a me ka wehe ʻana i ke kulekele waiwai.I ka lua o ka hapalua o ka malama, me ka hou-impact o ka maʻi ahulau a me ka sluggish koi i ka hopena o ka makahiki, ka lako a me ka koi pae i hāʻawi i ka maikaʻi manaʻo manaʻo, a me ka makeke komo mālie i ka hoʻohui haʻalulu.Ma kahi kokoke i ka hopena o ka makahiki, ua puka hou ka hopena hoʻomaha, e hōʻike ana i kahi ʻano piʻi holoʻokoʻa.
II, wahi anaana
He ʻelua ʻano kaʻina hana PVC: calcium carbide method a me ethylene method, ethylene method of PVC quality clean and uniform, ʻoi aku ka kiʻekiʻe o ke kumukūʻai ma mua o ka calcium carbide PVC method.ʻO ka hāʻawi ʻana i nā ʻano o ka wā e hiki mai ana PVC i ko mākou ʻāina ʻo SG5 grade 1 e like me ke kūlana aupuni.ʻAʻohe mea paʻa paʻa i ka hana ʻia ʻana o ka huahana e ka calcium carbide process a i ʻole ke kaʻina vinyl.
Ma ka lā 30 o Dekemaba, 2022, hōʻike ʻia ke kumukūʻai kiko a me ka laha o PVC ma lalo nei:
I kēlā lā, ʻo ke kumu kūʻai maʻamau o vinyl PVC ma Kina he 6,313 yuan/ton, ʻoi aku ka 165 yuan/ton i hoʻohālikelike ʻia me ka hopena o ka mahina i hala.
Ma ka lā hoʻokahi, ʻo ka awelika kumu kūʻai o ka calcium carbide PVC kūloko he 6,138 yuan/ton, ke hoʻohālikelike ʻia me ka hopena o ka mahina i hala, ʻoi aku ka 198 yuan/ton.
ʻO ka ʻokoʻa o ke kumu kūʻai ma waena o ke ʻano ethylene a me ke ʻano calcium carbide ma ia lā he 175 yuan/ton, ke hoʻohālikelike ʻia me ka hopena o ka mahina i hala, ua piʻi aʻe he 33 yuan/ton, aia nō ka ʻokoʻa o ke kumu kūʻai ma kahi pae haʻahaʻa.
Ma ka lā 30 o Kekemapa, 2022, ʻo ka laha ʻana o ke kumu kūʻai o ka PVC e hiki mai ana he -66 yuan/ton, 3 yuan/ton ka haʻahaʻa ma mua o ka lā ma mua, aia ma kahi haʻahaʻa o ka mōʻaukala.
III.Nānā hoʻolako
No ka manawa lōʻihi, ʻo ka mākeke PVC Kina he kumu hoʻomohala e noho pū ana me nā ʻano laina ʻenehana ʻelua, ke ʻano calcium carbide a me ke ʻano ethylene, akā ma muli o nā ʻano o nā kumu waiwai "ʻona waiwai, ʻaila maikaʻi ʻole a me ka liʻiliʻi o ke kinoea" i ko mākou ʻāina. Ua lilo ka calcium carbide method PVC i ka ʻenehana alakaʻi i ko mākou ʻāina, akā i ka mākeke honua, ua hana ʻia nā huahana PVC mainstream e ke ʻano ethylene, a ua hana ʻia ka ethylene e ka ikehu e like me ka aila a me ke kinoea.No laila ke kumu kūʻai o PVC a me nā kumukūʻai aila honua e hōʻike i kahi pilina paʻa.
ʻO ke ala kaʻina o ka vinyl PVC penei: ʻaila ʻaila - naphtha - ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Hoʻohana nui ʻia ke kaʻina hana calcium carbide i nā ʻoihana hana chlor-alkali Kina e hana ai i ka PVC, a ʻo ka hoʻopuka ʻana o PVC ma ke kaʻina hana calcium carbide e pili ana i ka 80% o ka huina o ka huahana ma Kina.
ʻO ke kaʻina hana o ka calcium carbide polyvinyl chloride ʻo ia: Coal - calcium carbide - acetylene - vinyl chloride (VCM) - polyvinyl chloride (PVC) ʻo ke ʻano hana hoʻohaʻahaʻa uila ʻo ia ke ʻano kumu nui o ka hana ʻana o ka calcium carbide i kēia manawa, lawe kēia ʻano i ka coke (2798). , 29.50, 1.07%) a me ka lime e like me nā mea maka, e like me ka lākiō paʻa i hui pū ʻia i loko o ka kapuahi calcium carbide i hoʻopaʻa ʻia, hana ʻia ka calcium carbide e ka hoʻomehana uila i 2000-2200 degere.No ka mea e pono ai kēia ala e hoʻopau i ka nui o ka ikehu uila, ʻo ke kumukūʻai uila ka helu kiʻekiʻe o ka nui o ke kumukūʻai no nā ʻoihana hana polyvinyl chloride e hoʻohana ana i ke ʻano calcium carbide.
ʻO ka hōʻuluʻulu ʻana, pili ke kumukūʻai o PVC i ka lanahu wela (0, -921.00, -100.00%) (ke kumu kūʻai uila), nā kumukūʻai coke a me ka calcium carbide i ka manawa like, e hōʻike ana i kahi pilina kiʻekiʻe.
Ma ka lā 03 o Ianuali, 2023, ʻo 921 yuan/ton ke kumu kūʻai o ka lānahu mana Kina, ke hoʻohālikelike ʻia me ka lā ma mua, ʻaʻohe loli;ʻO 2,610 yuan/ton ke kumu kūʻai o ka Coke, i hoʻohālikelike ʻia me ka lā ma mua, i lalo o 95 yuan/ton.
Ma ka lā 30 o Dekemaba, 2022, ʻo ka awelika kumu kūʻai o ka calcium carbide i nā hale hana calcium carbide mainstream ma Northwest China he 3,910 yuan/ton, ʻaʻohe loli i hoʻohālikelike ʻia me ka lā ma mua.ʻO ke kumu kūʻai o ka calcium carbide ma ka ʻāina he 4,101 yuan/ton, ke hoʻohālikelike ʻia me ka lā ma mua, ʻaʻohe loli.
Ke hana nā ʻoihana chlor-alkali i ka chlorine wai, loaʻa pū lākou i ka soda caustic, kahi huahana pili.I nā makahiki i hala iho nei, ʻo ke kumu kūʻai o ka soda caustic a me ka wai chlorine e hana i kahi hopena seesaw, ʻo ia hoʻi, ke kiʻekiʻe ke kumukūʻai o ka soda caustic, ʻoi aku ka haʻahaʻa o ke kumu kūʻai o ka chlorine wai, a ʻo ia ka mea e loaʻa ai ka waiwai o ka chlor-alkali. mālama nā ʻoihana i kahi pae kūpono.He paʻakikī ka wai chlorine e mālama a lawe ʻia ma kahi lōʻihi, no laila makemake nā mea hana e hoʻohui i ka PVC a hoʻohana i nā waiwai chlorine wai.
ʻO ka lalo o ka soda caustic ka nui o ka alumina, ka hana pepa, ka paʻi ʻana a me ke kala a me nā ʻoihana kemika.ʻO ka hoʻomehana ʻana o ka wai o lalo o ka soda caustic e alakaʻi i ka hoʻonui ʻia ʻana o ka hana ʻana o ka soda caustic o nā ʻoihana chlor-alkali, a e hana ʻia ka chlorine wai wai e pili ana i PVC, pēlā e hoʻonui ai i ka mākeke o PVC, kahi e kaomi ai i ke kumu kūʻai o ka mākeke. PVC i kekahi nui.Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o nā kumukūʻai PVC i ka wā e haʻahaʻa ai nā kumukūʻai soda caustic.
Ma ka lā 30 o Dekemaba, 2022, ʻo ke kumu kūʻai o ka ionic membrane caustic soda he 1,344 yuan/ton, ke hoʻohālikelike ʻia me ka lā ma mua, ʻaʻohe loli, a ʻo ke kumukūʻai o kēia manawa aia ma kahi kūlana kiʻekiʻe.
I kēia manawa, ʻo ka noi nui no ka soda caustic ma Kina mai ka pilina hana alumina, no laila ke hōʻike nei ke kumukūʻai o ka soda caustic a me ke kumu kūʻai o ka alumina i kahi pilina kiʻekiʻe.
Hoʻohana nui ʻia ka alumini electrolytic home i ka ʻoihana waiwai, kaʻa a me nā ʻoihana uila.ʻO ka hoʻihoʻi ʻana o kēia mau ʻoihana i lalo e hoʻonui i ka noi no nā huahana alumini, e hoʻouna ʻia i ka upstream, e koi ana i ke kumukūʻai caustic soda a pili ʻole i ke ʻano o ke kumukūʻai o nā wā e hiki mai ana PVC.
Ma ka lā 30 o Dekemaba, 2022, ʻo ke kumu kūʻai o ka alumina kūloko he 2,965 yuan/ton, ʻaʻohe loli i hoʻohālikelike ʻia me ka lā ma mua, a ʻo ke kumu kūʻai o kēia manawa aia ma ke kūlana awelika mōʻaukala.
