Ua wehe ʻia ka hoʻololi kiʻekiʻe o ka titanium dioxide

Ua hoʻomau ka mākeke titanium dioxide wela i ka hoʻomaʻalili ʻana no nā makahiki he nui mai ka hapa lua o ka makahiki i hala, a ua emi mālie ke kumukūʻai. A hiki i kēia manawa, ua hāʻule nā ​​​​kumukūʻai titanium dioxide ma mua o 20%. Eia nō naʻe, ma ke ʻano he huahana kiʻekiʻe i ka ʻoihana titanium dioxide, ua ikaika mau ke kaʻina hana chlorination titanium dioxide.

"ʻO ka chlorination titanium dioxide kekahi ʻano hoʻomohala o ka hoʻololi kiʻekiʻe o ka ʻoihana titanium dioxide o Kina. Ma ka lako mākeke, nā holomua ʻenehana, nā alakaʻi a me nā pono ʻē aʻe, i nā makahiki i hala iho nei, ua ulu mau ka hiki ke hana ʻana i ka titanium dioxide chloride kūloko, ʻoiai ka hana nui ʻana o nā lako titanium dioxide chloride Longbai Group i uhaʻi i ke kūlana e kū nei nā huahana kiʻekiʻe i nā ʻāina ʻē, a ua hala ka hoʻololi kiʻekiʻe o ka titanium dioxide kūloko ma ke alanui. " Wahi a Shao Huiwen, he mea kākau ʻōlelo mākeke kiʻekiʻe.

Ke hoʻomau nei ka ulu ʻana o ke kaʻina hana chlorination

"ʻElima mau makahiki i hala aku nei, ʻo nā huahana titanium dioxide chlorination he 3.6% wale nō o ka hana kūloko, a ua kaulike ʻole ke ʻano o ka ʻoihana." ʻOi aku ma mua o 90% o nā noi kiʻekiʻe kūloko o ka titanium dioxide e hilinaʻi nei i nā mea i lawe ʻia mai, ʻoi aku ke kumukūʻai ma kahi o 50% ma mua o ka titanium dioxide maʻamau kūloko. Loaʻa i nā huahana kiʻekiʻe kahi hilinaʻi nui o waho, a ʻaʻohe mana kūkākūkā ʻoihana ma nā huahana titanium dioxide chlorinated, ʻo ia hoʻi ka bottleneck o ka hoʻololi kiʻekiʻe a me ka hoʻonui ʻana o ka ʻoihana titanium dioxide o Kina. "ʻ saidlelo ʻo ia ʻo Benliu.

Ua hōʻike ʻia nā helu helu dute i ka hapaha mua o 2023, ua hōʻiliʻili ʻia nā mea i lawe ʻia mai ka titanium dioxide mai Kina ma kahi o 13,200 tons, i emi iho he 64.25% i kēlā me kēia makahiki; ʻO ka nui o ka hoʻokuʻu aku ma kahi o 437,100 tons, he piʻi ʻana o 12.65%. Wahi a nā ʻikepili ʻē aʻe, ʻo ka hiki ke hana i ka titanium dioxide o Kina i ka makahiki 2022 he 4.7 miliona tons, ua emi nā mea i lawe ʻia mai he 43% mai ka makahiki 2017, a ua piʻi aʻe nā mea i lawe ʻia aku he 290% mai ka makahiki 2012. "I nā makahiki i hala iho nei, ua emi nā mea i lawe ʻia mai ka titanium dioxide kūloko a ua piʻi ka nui o ka mea i lawe ʻia aku, no ka mea, ʻo ka hoʻonui wikiwiki ʻana o ka hiki ke hana i ka titanium dioxide chloride o nā ʻoihana alakaʻi kūloko ua hoʻēmi maikaʻi i ka hilinaʻi ʻana i nā huahana kiʻekiʻe i lawe ʻia mai." Wahi a ke kanaka nāna e mālama i kahi ʻoihana uhi kūloko.

Wahi a He Benliu, ua māhele ʻia ke kaʻina hana nui o ka titanium dioxide i ke ʻano sulfuric acid, ke ʻano chlorination a me ke ʻano hydrochloric acid, nona ke kaʻina hana chlorination pōkole, maʻalahi ka hoʻonui ʻana i ka hiki ke hana, kiʻekiʻe o ka automation hoʻomau, haʻahaʻa ka hoʻohana ʻana i ka ikehu, emi ka hoʻokuʻu ʻana o "ʻekolu ʻōpala", hiki ke loaʻa nā huahana kiʻekiʻe, ʻo ia ke kaʻina hana nui o ka ʻoihana titanium dioxide. ʻO ka lakio o ka hiki ke hana i ka titanium dioxide chlorination honua a me ka sulfuric acid titanium dioxide ma kahi o 6:4, ma ʻEulopa a me ʻAmelika Hui Pū ʻIa, ʻoi aku ka nui o ka chlorination, ua piʻi ka hapa o Kina i 3:7, a e hoʻomau ʻia ka hoʻomaikaʻi ʻana i ka wā e hiki mai ana no ka hoʻomākaukau ʻana i ka titanium dioxide chlorination.

Ua helu ʻia ka chlorination ma ka māhele i paipai ʻia

ʻO ka "Industrial structure Adjustment Guidance Catalogue" i hoʻopuka ʻia e ka National Development and Reform Commission i helu i ka hana ʻana o ka titanium dioxide chlorinated ma ke ʻano i paipai ʻia, ʻoiai e kaupalena ana i ka hana hou ʻole o ka titanium dioxide sulfuric acid, ka mea i lilo i manawa kūpono no ka hoʻololi a me ka hoʻonui ʻana i nā ʻoihana titanium dioxide, mai ia manawa ua hoʻomaka nā ʻoihana titanium dioxide kūloko e hoʻonui i ka noiʻi a me ka hoʻomohala ʻana a me ka noiʻi noiʻi i ka ʻenehana hana o ka titanium dioxide chlorinated.

Ma hope o nā makahiki o ka noiʻi loea, no ka hoʻoponopono ʻana i kekahi mau pilikia i ka chloride titanium dioxide, ua hoʻomohala ʻo Longbai Group i kekahi mau huahana kiʻekiʻe o nā huahana chloride titanium dioxide kiʻekiʻe, ua hōʻea ka hana holoʻokoʻa i ka pae holomua honua, a ua hōʻea kekahi hana i ka pae alakaʻi honua. ʻO mākou ka noi hou mua o nā ʻoihana ʻenehana chlorination titanium dioxide hoʻolapalapa nui, ua hōʻoia pū ka hana he ʻoi aku ka ʻōmaʻomaʻo a me ka launa pū ʻana o ke kaiapuni o ka ʻenehana chlorination titanium dioxide, ʻoi aku ka nui o ka hoʻohana ʻana i ka ʻōpala ma mua o ke ʻano sulfuric acid e hōʻemi i ka ʻoi aku ma mua o 90%, ka mālama ikehu piha a hiki i ka 30%, ka mālama wai a hiki i ka 50%, he mea nui loa nā pono o ke kaiapuni, a ua hoʻokō ka hana huahana i nā kūlana lawe mai, i hoʻokahi manawa, ua haki ka monopoly haole ma ka mākeke kiʻekiʻe, a ua ʻike ʻia nā huahana e ka mākeke.

Me ka hana hou ʻana o nā papahana titanium dioxide chlorinated kūloko hou, ua hōʻea kona hiki ke hana ma kahi o 1.08 miliona tons ma 2022, e helu ana i ka nui o ka hiki ke hana kūloko ua piʻi aʻe mai 3.6% ʻelima mau makahiki i hala aku nei a ʻoi aku ma mua o 22%, e hōʻemi nui ana i ka hilinaʻi o waho o ka titanium dioxide chlorinated, a ua hoʻomaka ka loaʻa ʻana o ka pono o ka mākeke.

Manaʻo nā poʻe loea o ka ʻoihana ma muli o ke ʻano hoʻomohala o ka noi titanium dioxide kiʻekiʻe, a me ke ʻano o kēia manawa a me ke kūlana o ka ʻoihana kūloko, ua hoʻomaka ka hoʻololi ʻana o ka titanium dioxide kiʻekiʻe o Kina e uhaʻi i ka pāʻani. Ua manaʻo ʻia e hoʻonui nā keʻena aupuni a me nā ʻoihana pili i ka nānā a me ke alakaʻi ʻana i ka hoʻolālā papahana chlorination, a pono hoʻi e kuhikuhi ʻia nā ʻoihana, e haʻalele i ka hoʻopukapuka kālā papahana a me ka hoʻolālā ʻana o nā kaʻina hana hope a me nā huahana hope, a e kālele i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā huahana kiʻekiʻe e pale aku i ka pilikia o nā huahana haʻahaʻa keu.
