He mea hoʻoheheʻe aprotic ʻo N-Methyl-2-pyrrolidone me nā ʻano hana like ʻole: ka hana petrochemical, ka uhi ʻana i ka ʻili, nā dyes a me nā pgments, nā hui hoʻomaʻemaʻe ʻoihana a me ka home, a me nā ʻano hana mahiʻai a me nā lāʻau lapaʻau. He mea hoʻonāukiuki nui ia, akā ua hoʻoulu pū i kekahi mau hihia o ka dermatitis pili i kahi hui electrotechnical liʻiliʻi.

Hoʻohana
Nā hoʻohana
ʻO N-Methyl-2-pyrrolidone (NMP) kahi mea hoʻoheheʻe aprotic polar nona nā pono o ka haʻahaʻa haʻahaʻa, ke kiko paila kiʻekiʻe, ka solvency koʻikoʻi, ke koho ikaika a me ke kūpaʻa maikaʻi.
Hoʻohana nui ʻia ia i ka hoʻomaʻemaʻe ʻana i ka unuhi ʻana o ka hydrocarbon ʻala, acetylene, olefins, a me diolefins.
Hoʻohana ʻia ia i ka hoʻomaʻemaʻe ʻoihana, a lawelawe ia ma ke ʻano he mea hoʻoheheʻe no ka hana ʻana i nā pesticides, nā plastics ʻenekinia, nā uhi, nā fibers synthetic, a me nā kaapuni i hoʻohui ʻia.
Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe ʻoihana, mea hoʻolaha, mea hoʻoluʻu, mea lubricant a me ka antifreeze.
He mea hoʻoheheʻe maikaʻi loa ʻo N-Methyl-2-pyrrolidone, hoʻohana nui ʻia i ka unuhi ʻana i nā mea ʻala, ka hoʻomaʻemaʻe ʻana i ka ʻaila lubricating, ka hoʻonui ʻana i ka acetylene, ka hoʻokaʻawale butadiene a me ka desulfurization kinoea synthesis.
Hoʻohana ʻia ia i ka desulfurization kinoea, ka hoʻomaʻemaʻe ʻaila lubricating, ka antifreeze ʻaila lubricating, ka unuhi ʻana o ka olefin, a ma ke ʻano he solvent no ka polymerization plastics ʻenekinia insoluble.
Hiki ke hoʻohana ʻia i ka herbicide, e hoʻomaʻemaʻe i nā mea insulation, nā mea hana pololei o ka ʻoihana semiconductor a me nā papa kaapuni, e hana hou i ka PVC exhaust, ma ke ʻano he detergent, dye complement a me ka dispersing agent.
Hoʻohana ʻia ia i nā medium no nā hopena polymerization e like me nā plastics engineering a me ka fiber aramid.
Hoʻohana ʻia ʻo N-Methyl-2-pyrrolidone ma ke ʻano he mea hoʻoheheʻe polyvinylidene fluoride a me kahi mea kōkua electrode no nā pila lithium ion.
papa maʻemaʻe kiʻekiʻe no ka ʻike ʻana i ka ICP-MS.
No ka hoʻohuihui ʻana o ka peptide.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
