I ka makahiki 2022, ua hōʻike ka mākeke kemika kūloko i kahi emi kūpono. I loko o ke ʻano o ka piʻi ʻana a me ka hāʻule ʻana, ʻoi aku ka maikaʻi o ka hana o ka mākeke kemika ikehu hou ma mua o ka ʻoihana kemika kuʻuna a ke alakaʻi nei i ka mākeke.
Hoʻokele ʻia ke kumumanaʻo o ka ikehu hou, a ua piʻi aʻe nā mea maka o luna. Wahi a nā helu helu, ʻo nā huahana kemika ʻelima kiʻekiʻe loa i ka makahiki 2022 ʻo ia ka lithium hydroxide, lithium carbonate (nā huahana ʻoihana), butadiene, lithium iron phosphate, a me ka phosphate ore. I waena o lākou, koe wale nō ka phosphorus ore i pili i ke kumumanaʻo o ka ikehu hou. I ka makahiki 2022, i hoʻokele ʻia e ka ʻoihana kaʻa ikehu hou, ua hōʻike ʻia nā kumukūʻai o ka lithium hydroxide, lithium carbonate, a me ka lithium iron phosphate, e pili pono ana i nā pila lithium. Ma ke ʻano he huahana i pili pono me nā kaʻa ikehu hou, ua hiki aku ka butadiene i 144% i ka hapa mua o 2022. Ua pōmaikaʻi ka phosphorus ore mai ka piʻi ʻana o ke koi no ka phosphate fertilizer a me nā kumuwaiwai palena o nā kumuwaiwai, a ua hoʻomau i ka piʻi ʻana mai ka makahiki 2021.
ʻO ka hopena maʻamau o ka mākeke huahana kemika kuʻuna. I ka makahiki 2022, ua hōʻike ka hapa nui o nā huahana kemika kuʻuna i kahi emi nui, a ua maopopo ka hopena o ke kaulahao ʻoihana. No ka laʻana, ʻo ka emi ʻana o ka 1,4-butanol, tetrahydrofuu, N, N-di metamimamamide (DMF), dichlorogenesis, sulfuric acid, acetic acid, hydrochloric acid, etc., ʻo ka emi ʻana he 68%, 68%, 61, kēlā me kēia. %, 60%, 56%, 52%, 45%. Eia kekahi, ʻo ka emi ʻana o nā huahana e like me ka anhydride palupalu, sulfur, titanium pink, a me ka phenol he 22% a 43%. Mai ke ʻano o kēia mau huahana, hiki ke ʻike ʻia ua hoʻomaka ka piʻi mua ʻana o nā huahana kemika kuʻuna e hāʻule me ka noʻonoʻo, ua nāwaliwali nā ʻāpana kuhi kekahi ma hope o kekahi, a ua hoʻokumu i ka hopena emi honua o ke kaulahao huahana pili.
Hoʻopaʻa ʻia nā mea maka kumu ma nā pae kiʻekiʻe a hoʻi pinepine i ke kānāwai o ka mākeke. ʻO kekahi ʻano o ka mākeke huahana kemika i ka makahiki 2022, ʻo ia ka paʻa ʻana o nā huahana mea maka kumu ma ka pae waena a kiʻekiʻe, a paʻi i kahi kiʻekiʻe hou i ka hapa mua o ka makahiki, a ua hoʻōla maikaʻi ʻia ka hapa lua o ka makahiki. ʻOiai ua hāʻule nā kumukūʻai o kekahi mau kumuwaiwai nui, nā ʻano organik, inorganic, a me nā mea hoʻouluulu i ka hapa lua o ka makahiki, ua hoʻihoʻi hou lākou i ka wā ma hope, a hoʻi hou i ke kānāwai mākeke. No ka laʻana, ʻo ka piʻi ʻana o ka makahiki he 13%, 12%, 9%, a me 5% o ka pyrine, benzide, nitric acid, a me ka aniline, i hoʻemi maikaʻi ʻia i ka wā i kiʻekiʻe ai ka mākeke i ka waena o 2022 a i ʻole ʻOkakopa. No ka mea, ua koi nui ʻia kēia mau huahana kemika no nā mea maka kumu, hiki iā lākou ke mālama i kahi kūlana mākeke ikaika ma hope o ka hoʻoponopono ʻana i ka emi ʻana. Eia kekahi, ua hāʻule nā huahana e like me ka cycloidone, benzene maʻemaʻe, ethylene oxide, styrene, a me ka acryline ma 14%, 10%, 9%, 5%, a me 4%. Ma hope o kēia mau piʻi ʻana, ua hāʻule lākou i loko o 14% o ka piʻi ʻana a me ka emi ʻana i loko o 14%. Aia ke kumukūʻai paʻa ma ke kūlana waena a kiʻekiʻe, a ua paʻa iki. Ua hoʻoikaika mālie ʻia ke kuleana o nā kānāwai lako a me ke koi o ka mākeke.
Ua hōʻike ʻia ka loiloi piha i ka makahiki 2022, e hōʻike ana ka mākeke huahana kemika i kahi kaʻina hana hoʻōla mākeke o ka hoʻi ʻana i ka noʻonoʻo a me ka mālama ʻana i nā lula mākeke. I ka manawa like, ua hoʻomaha ka manaʻo kuhi mākeke, kahi mea i ʻike nui ʻia ma ka mākeke huahana kemika kuʻuna. Ke nānā nei i ka wā e hiki mai ana, manaʻo ʻia e emi iho nā huahana maka kumu a paʻa i ka makahiki 2023, ʻaʻole kāpae nā huahana kemika kuʻuna i ka hiki ke hoʻopaʻa ʻia i lalo, he paʻakikī ke hōʻike i ka piʻi ʻana o nā huahana ikehu hou i ka makahiki 2022, akā ke hoʻohiki nei ka manaʻolana hoʻomohala.
