He mea hoʻoheheʻe koʻikoʻi ka Methylene Chloride i ka ʻoihana, a ʻo kona hoʻomohala ʻana i ka ʻoihana a me ka noiʻi ʻepekema he mau kumuhana ia o ka nānā nui ʻia. E hōʻike ana kēia ʻatikala i kāna mau hoʻomohala hou loa mai nā ʻano ʻehā: ke ʻano o ka mākeke, nā dinamika hoʻoponopono, nā ʻano kumukūʻai, a me ka holomua o ka noiʻi ʻepekema hou loa.
ʻAno o ka MākekeUa paʻa loa ka mākeke honua, me nā mea hana ʻekolu kiʻekiʻe (e like me Juhua Group, Lee & Man Chemical, a me Jinling Group) e paʻa ana i kahi māhele mākeke i hui pū ʻia o kahi 33%. ʻO ka ʻāina ʻo Asia-Pākīpika ka mākeke nui loa, e helu ana ma kahi o 75% o ka māhele.
Nā Dinamika Hoʻoponopono:Ua hoʻopuka ka US Environmental Protection Agency (EPA) i kahi lula hope loa ma lalo o ke Toxic Substances Control Act (TSCA) e pāpā ana i ka hoʻohana ʻana i ka methylene chloride i nā huahana mea kūʻai e like me nā mea ʻoki pena a me ke kau ʻana i nā kapu paʻa i ka hoʻohana ʻana i nā ʻoihana.
Nā ʻAno Kumukūʻai: I ʻAukake 2025, ma muli o ke kiʻekiʻe o ka hana ʻoihana e alakaʻi ana i ka lako lawa, me ke kau ʻole no ke koi a me ka lawa ʻole o ka hoihoi kūʻai ma hope, ua hāʻule nā kumukūʻai mai kekahi mau mea hana ma lalo o ka māka 2000 RMB/ton.
Kūlana Kālepa:Mai Ianuali a Mei 2025, ua piʻi nui ka hoʻokuʻu aku o Kina i ka methylene chloride (makahiki ma ka makahiki +26.1%), i hoʻolālā nui ʻia no Asia Hikina Hema, India, a me nā wahi ʻē aʻe, kahi e kōkua ai i ka hōʻoluʻolu ʻana i ke kaomi lako kūloko.
Nā Palena i ka Noiʻi ʻenehana Hou Loa
Ma ke kahua o ka noiʻi ʻepekema, ke holomua nei nā haʻawina e pili ana i ka methylene chloride a me nā hui pili i nā kuhikuhi ʻōmaʻomaʻo a ʻoi aku ka maikaʻi. Eia kekahi mau kuhikuhi koʻikoʻi:
Nā ʻAno Hana Hoʻohui ʻŌmaʻomaʻo:Ua paʻi kahi hui noiʻi mai ke Kulanui ʻenehana ʻo Shandong i kahi noiʻi hou i ʻApelila 2025, e hāpai ana i kahi manaʻo hou o ka "magnetically driven redox." Hoʻohana kēia ʻenehana i kahi kahua magnetic wili e hana i kahi ikaika electromotive i hoʻokomo ʻia i loko o kahi alakaʻi metala, a laila e hoʻokele ana i nā hopena kemika. Ua hōʻailona kēia noiʻi i ka hoʻohana mua ʻana o kēia hoʻolālā i ka catalysis metala hoʻololi, me ka hoʻokō pono ʻana i ka reductive cross-coupling o nā aryl chlorides reactive liʻiliʻi me nā alkyl chlorides. Hāʻawi kēia i kahi ala hou no ka hoʻoulu ʻana i nā pilina kemika inert (e like me nā pilina C-Cl) ma lalo o nā kūlana akahai, me ka hiki ke hoʻohana ākea.
Hoʻonui i ke kaʻina hana hoʻokaʻawale:I ka hana kemika, ʻo ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana nā ʻanuʻu nui e hoʻopau ai i ka ikehu. Ke nānā nei kekahi mau noiʻi i ka hoʻomohala ʻana i nā mea hana hou no ka hoʻokaʻawale ʻana i nā hui hopena mai ka methylene chloride synthesis. Ua ʻimi kēia noiʻi i ka hoʻohana ʻana i ka methanol ma ke ʻano he mea hoʻokaʻawale ponoʻī e hoʻokaʻawale i nā hui o ka dimethyl ether-methyl chloride me ka volatility haʻahaʻa, e manaʻo ana e hoʻomaikaʻi i ka pono o ka hoʻokaʻawale ʻana a hoʻonui i nā ʻano hana.
Ka ʻimi ʻana i nā noi ma nā ʻōnaehana hoʻoheheʻe hou:ʻOiai ʻaʻole pili pono i ka methylene chloride, he mea nui loa kahi noiʻi e pili ana i nā solvents eutectic hohonu (DES) i paʻi ʻia ma PMC i ʻAukake 2025. Ua hāʻawi kēia noiʻi i nā ʻike hohonu i ke ʻano o nā pilina molekala i loko o nā ʻōnaehana solvent. Hiki i nā holomua i loko o ia mau ʻenehana solvent ʻōmaʻomaʻo, i ka wā lōʻihi, ke hāʻawi i nā mea hou no ka hoʻololi ʻana i kekahi mau solvents organic volatile kuʻuna, me ka methylene chloride.
I ka hōʻuluʻulu manaʻo, aia ka ʻoihana methylene chloride i kahi manawa hoʻololi i hōʻailona ʻia e nā manawa kūpono a me nā pilikia.
Nā pilikiaua ʻike nui ʻia i nā lula kaiapuni paʻa (ʻoi aku hoʻi ma nā mākeke e like me ʻEulopa a me ʻAmelika Hui Pū ʻIa) a me ka emi ʻana o ke koi ma kekahi mau wahi hoʻohana kuʻuna (e like me nā mea ʻoki pena).
Nā manawa kūponoakā naʻe, aia i loko o ke koi mau i loko o nā ʻāpana kahi i loaʻa ʻole ai nā pani kūpono (e like me nā lāʻau lapaʻau a me ka synthesis kemika). I ka manawa like, ʻo ka hoʻomau mau ʻana o nā kaʻina hana a me ka hoʻonui ʻana o nā mākeke hoʻokuʻu aku e hāʻawi pū ana i ka momentum no ka hoʻomohala ʻana o ka ʻoihana.
Manaʻo ʻia ka hoʻomohala ʻana i ka wā e hiki mai ana e hilinaʻi nui aku i nā huahana hana kiʻekiʻe, maʻemaʻe kiʻekiʻe a me nā hana hou ʻenehana e kūlike me nā kumumanaʻo o ka kemika ʻōmaʻomaʻo.
Ka manawa hoʻouna: Sep-26-2025
