ʻO ka wai aniani ʻaʻohe waihoʻoluʻu a i ʻole ka wai melemele māmā me ka ʻala iʻa
1. He mea hoʻoheheʻe organik maikaʻi loa ia, i hoʻohana ʻia e like me ka solvent no ka polyurethane, polyacrylonitrile, a me ka polyvinyl chloride.Hoʻohana ʻia ia ma ke ʻano he mea maka no nā extractants, nā lāʻau lapaʻau a me nā pesticides.
2. Hoʻohana ʻia e like me ka analytical reagent a me ka solvent no ka vinyl resin a me ka acetylene
3. ʻAʻole ʻo Dimethylformamide wale nō kahi mea hoʻoheheʻe kemika maikaʻi loa.ʻO ka dimethylformamide he mea hoʻoheheʻe maikaʻi no nāʻano polymers likeʻole e like me polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, a me nā mea'ē aʻe, a hiki ke hoʻohanaʻia no ka wili pulu o nā fibers synthetic e like me ka polyacrylonitrile fiber, a me ka synthesis o polyurethane;Hoʻohana ʻia i ka hana kiʻiʻoniʻoni plastik;hiki ke hoʻohana ʻia e like me ka wehe ʻana i ka pena e wehe i ka pena;hiki iā ia ke hoʻoheheʻe i kekahi mau puaʻa haʻahaʻa haʻahaʻa, e hāʻawi ana i nā puaʻa i nā ʻano o nā mea pena.Hoʻohana ʻia ka Dimethylformamide no ka unuhi ʻana a me ka hoʻokaʻawale ʻana o ka butadiene mai ka hakina C4 a me ka isoprene mai ka hakina C5.Hiki ke hoʻohana ʻia ma ke ʻano he reagent kūpono no ka hoʻokaʻawale ʻana i nā ʻāpana non-hydrocarbon mai ka paraffin..Loaʻa iā ia ke koho maikaʻi i ka solubility o ka isophthalic acid a me ka terephthalic acid: ʻoi aku ka nui o ka solubility o ka isophthalic acid i ka dimethylformamide ma mua o ka terephthalic acid.Hiki i ka Chemicalbook ke hoʻokaʻawale i nā mea ʻelua.I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ka dimethylformamide ma ke ʻano he mea hoʻoheheʻe kinoea e hoʻokaʻawale a hoʻomaʻemaʻe i ke kinoea.I loko o nā hopena kūlohelohe, ʻaʻole i hoʻohana nui ʻia ka dimethylformamide ma ke ʻano he solvent no ka hopena, akā he mea koʻikoʻi hoʻi i ka synthesis organik.I ka ʻoihana pesticide, hiki ke hoʻohana ʻia e hana i nā insecticide;i ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize iodosamine, doxycycline, cortisone, vitamin B6, iodoside, ququjing, pyrantel, N-formyllysar Onumaric acid, methoxy mustard, chlorambucil, nitrosourea, furfurouracil, tranexamic acid, fentrolmethasone. chlorpheniramine, etc. He hopena catalytic ka Dimethylformamide i nā hopena o ka hydrogenation, dehydrogenation, dehydration a me ka dehydrohalogenation, e hoʻemi ana i ka mahana hopena a hoʻomaikaʻi i ka maʻemaʻe o ka huahana.
4.Titration o nā mea hoʻoheheʻe wai ʻole.Mea hoʻoheheʻe no ka resin vinyl a me ka acetylene.Hoʻoholo kiʻi kiʻi.ʻO ke kinoea chromatographic stationary wai (ʻoi loa ka hoʻohana ʻana i ka mahana he 50 ℃, ka mea hoʻoheheʻe he methanol), hoʻokaʻawale ʻo Chemicalbook no ka nānā ʻana i nā hydrocarbons C2-C5, a hiki ke hoʻokaʻawale i ka maʻamau a me ka isobutene a me ka cis a me ka trans-2-butene.Ka nānā 'ana i nā koena pesticide.Hoʻohui ʻia.ʻO ka hui ʻana o nā peptides.No ka ʻoihana kiʻi.

E pili ana iā mākou
MIT-IVY INDUSTRY Co., Ltd.Hana ʻia ʻo Fine Chemical Source.
Hāʻawi iā ʻoe i nā huahana maikaʻi loa, nā kumukūʻai maikaʻi loa, a me ka lawelawe hopohopo ʻole.
ʻAno maikaʻi: ikaika ke alakaʻi ʻoihana
Ma ke ʻano he pae ʻoihana no nā lawelawe kaulahao hoʻolako i ke kahua o nā huahana kemika ma Kina, ua hoʻolako piha ʻia me kahi ʻōnaehana hana pololei a ua hoʻokumu i ka pilina paʻa a hilinaʻi lōʻihi me nā ʻoihana kemika kaulana a me nā mea kanu kemika nui. .
Kumukūʻai: Nā huahana kiʻekiʻe, nā kumukūʻai kiʻekiʻe
Hoʻolohe ka hui i ke kaʻina hana o ka maikaʻi o ka huahana, ke koi nei e hana wale i nā "huahana maoli";ke koi nei i ka manaʻo o ka holomua like me nā mea kūʻai aku a lanakila-lanakila hui.ʻO ka hāʻawi ʻana i nā kumukūʻai pono mākeke, ua lanakila i ka inoa maikaʻi ma waena o nā mea kūʻai aku he nui.
Service: ʻOihana hui, lawelawe mua
Loaʻa iā mākou ka ʻike waiwai ma ke kālepa honua, nā ʻoihana i ka ʻoihana kemika, a me kahi hui kūʻai ʻoihana me ka lawelawe hoʻomaʻemaʻe "hoʻokahi-a-kahi".E like me kāu mau pono, e hāʻawi mākou iā ʻoe i ka ʻōlelo kikoʻī a me nā lawelawe kūkākūkā i ka manawa kūpono, a nānā pono i kāu mau kūʻai.
ʻO ka lawe ʻana: Logistic kūpono a me ka lawe uila
Loaʻa i ka hui kona mau'auwaʻa pono'ī a ua kau inoa i kekahi mau hui logistics kaulana. Hāʻawi iāʻoe i ka holo wikiwiki, palekana a pololei.
Spot: Loaʻa nā ʻano like ʻole a lawa ka waihona
Ke hana nei ka hui i kēia manawa ma mua o 100 mau ʻano huahana kemika, a ua hoʻopaʻa ʻia nā hale kūʻai ʻeke a me nā pahu mālama wai ma Nantong, Shanghai, Lianyungang, Changzhou, Xuzhou, a me Inner Mongolia.
Hiki ke mālama nui a me ka lako paʻa.
