ʻO ka Methylene Chloride kahi mea hoʻoheheʻe ʻoihana koʻikoʻi, a ʻo kāna hoʻomohala ʻana i ka ʻoihana a me ka noiʻi ʻepekema ʻo ia nā kumuhana e nānā nui ʻia. E hōʻike ana kēia ʻatikala i kāna mau hana hou mai nā ʻano ʻehā: ka hoʻolālā mākeke, nā hoʻoponopono hoʻoponopono, nā ʻano kumu kūʻai, a me ka holomua noiʻi ʻepekema hou loa.
Hale kuai: Ua koʻikoʻi 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 mākeke hui ʻia ma kahi o 33%. ʻO ka ʻāina ʻo Asia-Pacific ka mākeke nui loa, e helu ana ma kahi o 75% o ka māhele.
Nā Dynamics Hoʻoponopono:Ua hoʻopuka ka US Environmental Protection Agency (EPA) i ke kānāwai 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 aku e like me nā mea pena pena a me ke kau ʻana i nā palena paʻa i nā hoʻohana ʻoihana.
Nā Kūlana Kūʻai: Ma ʻAukake 2025, ma muli o ka nui o ka hana ʻoihana e alakaʻi ana i ka lako lako, i hui pū ʻia me ka manawa ʻole no ka noi a me ka lawa ʻole o ke kūʻai ʻana i lalo, ua hāʻule nā kumukūʻai mai kekahi mau mea hana ma lalo o ka hōʻailona 2000 RMB/ton.
Kūʻai Kūʻai:Mai Ianuali a Mei 2025, ua hoʻonui nui ʻia ka hoʻokuʻu ʻana o Kina i ka methylene chloride (makahiki-ma-makahiki +26.1%), ka mea i koho mua ʻia no Asia Hikina Hema, India, a me nā wahi ʻē aʻe, e kōkua ana i ka hoʻohaʻahaʻa ʻana i ke kaumaha o ka lako home.
Nā Frontiers i ka ʻimi noiʻi ʻenehana hou loa
Ma ke kahua o ka noiʻi ʻepekema, ke neʻe nei nā haʻawina e pili ana i ka methylene chloride a me nā pūhui pili i nā kuhikuhi ʻōmaʻomaʻo a ʻoi aku ka maikaʻi. Eia kekahi mau kuhikuhi nui:
Nā ʻano hana ʻōmaʻomaʻo:Ua paʻi kahi hui noiʻi mai ke Kulanui o ʻenehana ʻo Shandong i kahi noiʻi hou i ʻApelila 2025, e noi ana i kahi manaʻo hou o ka "redox hoʻokele magnetic." Ke hoʻohana nei kēia ʻenehana i kahi kahua magnetic rotating e hoʻoulu ai i ka mana electromotive i hoʻokomo ʻia i loko o kahi conductor metala, a laila e hoʻokau i nā hopena kemika. Ua hōʻailona kēia haʻawina i ka hoʻohana mua ʻana o kēia hoʻolālā i ka hoʻololi metala catalysis, e hoʻokō pono ana i ka hoʻohui ʻana i ke keʻa hoʻemi o nā aril chlorides liʻiliʻi me nā alkyl chlorides. Hāʻawi kēia i kahi ala hou no ka hoʻāla ʻana i nā mea paʻa kemika inert (e like me nā paʻa C-Cl) ma lalo o nā kūlana haʻahaʻa, me ka hiki ke hoʻohana ākea.
ʻO ka hoʻokaʻawale ʻana i ke kaʻina hana:I ka hana kemika, ʻo ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā hana nui e hoʻopau 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 ʻana mai ka methylene chloride synthesis. Ua ʻimi kēia noiʻi ʻana i ka hoʻohana ʻana i ka methanol ma ke ʻano he mea hoʻokaʻawale ponoʻī e hoʻokaʻawale i nā hui ʻana o ka dimethyl ether-methyl chloride me ka haʻahaʻa haʻahaʻa, me ka manaʻo e hoʻomaikaʻi i ka hoʻokaʻawale ʻana a me ka hoʻomaikaʻi ʻana i nā ʻāpana kaʻina hana.
ʻImi ʻana i nā noi ma nā ʻōnaehana Solvent Hou:ʻOiai ʻaʻole pili pono i ka methylene chloride, he mea koʻikoʻi ka noiʻi ʻana i nā solvents eutectic hohonu (DES) i paʻi ʻia ma PMC ma ʻAukake 2025. Hāʻawi kēia haʻawina i nā ʻike hohonu i ke ʻano o ka pilina molekala i loko o nā ʻōnaehana solvent. Hiki i nā holomua o ia ʻenehana solvent ʻōmaʻomaʻo, i ka wā lōʻihi, ke hāʻawi i nā mea hou no ka hoʻololi ʻana i kekahi mau mea hoʻoheheʻe kūlohelohe kūlohelohe, me ka methylene chloride.
I ka hōʻuluʻulu ʻana, aia ka ʻoihana methylene chloride i kahi manawa hoʻololi i hōʻike ʻia e nā manawa a me nā pilikia.
Nā pilikiaʻike ʻia i loko o nā hoʻoponopono kaiapuni e piʻi aʻe ana (ʻoi aku ma nā mākeke e like me ʻEulopa a me US) a me ka hopena o ka koi ʻana ma kekahi mau wahi noi kuʻuna (e like me nā mea pena pena).
Nā manawa kūpono, eia naʻe, aia i ka koi mau i loko o nā ʻāpana kahi i ʻike ʻole ʻia ai nā pani kūpono (e like me ka 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 i nā mākeke hoʻopukapuka e hāʻawi pū ana i ka manawa no ka hoʻomohala ʻana o ka ʻoihana.
Manaʻo ʻia ka hoʻomohala ʻana i ka wā e hiki mai ana e hilinaʻi hou aku i nā huahana kūikawā kiʻekiʻe, hoʻomaʻemaʻe kiʻekiʻe a me nā hana ʻenehana i kūlike me nā loina o ka kemika ʻōmaʻomaʻo.
