Kumukūʻai maikaʻi o ka mea hana N-METHYL PYRROLIDONE (NMP) CAS: 872-50-4

ʻO N-methylpyrrolidone (NMP) kahi mea hoʻoheheʻe aprotic polar. He haʻahaʻa kona ʻawahia, kiʻekiʻe ka paila a me ka solubility koʻikoʻi. ʻO nā pono o ke koho ikaika a me ke kūpaʻa maikaʻi. Hoʻohana nui ʻia i ka unuhi ʻana o ka hydrocarbon ʻala, ka hoʻomaʻemaʻe ʻana o ka acetylene, olefins a me diolefins, nā mea hoʻoheheʻe no ka polyvinylidene fluoride, nā mea kōkua electrode no nā pila lithium ion, syngas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extractant, paʻakikī nā mea hoʻoheheʻe i ka polymerization o nā plastics ʻenekinia, nā herbicides mahiʻai, nā mea insulating, ka hana kaapuni hoʻohui, ka hoʻomaʻemaʻe ʻana i nā mea hana pololei i ka ʻoihana semiconductor, nā papa kaapuni, ka hoʻōla kinoea PVC, nā mea hoʻomaʻemaʻe, nā mea kōkua dye, nā mea hoʻolaha, a pēlā aku. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻoheheʻe no nā polymers a me kahi medium no ka polymerization, e like me nā plastics ʻenekinia a me nā fiber aramid. Hiki ke hoʻohana ʻia i nā pesticides, nā lāʻau lapaʻau a me nā mea hoʻomaʻemaʻe. Aia ma lalo nā hoʻohana nui o nā papa like ʻole o N-methylpyrrolidone:

1. Papa ʻoihana: hoʻomaʻemaʻe ʻaila lubricating, antifreeze ʻaila lubricating, desulfurization syngas, nā mea insulation uila, nā herbicides mahiʻai, nā mea kōkua pesticide, ka hoʻōla kinoea hoʻopau PVC, nā mea kōkua a me nā mea hoʻolaha no ka hana ʻana i nā uhi kiʻekiʻe, nā inika, nā pigments, a pēlā aku. No ka laʻana, hoʻohana ʻia ia e unuhi i nā hydrocarbons ʻala i loko o ka ʻaila lubricating e hoʻokō ai i ke kumu o ka hoʻomaʻemaʻe ʻana i ka ʻaila lubricating; ma muli o ke kiʻekiʻe o ka solubility o NMP i ka resin, hiki ke hoʻohana ʻia ma ke ʻano he solvent no ka resin a me Chemicalbook e hoʻohana ʻia i ka hana ʻana i nā uhi, nā pena papahele, nā varnish, nā uhi composite, nā kiʻiʻoniʻoni, nā mea insulation wire enameled Circuit i hoʻohui ʻia, nā lole fiber a me nā adhesives a me nā huahana ʻē aʻe.

2. Papa maʻamau: ka unuhi ʻana a me ka hoʻōla ʻana i nā mea maka organik kumu, e like me ka acetylene concentration a me ka unuhi ʻana o ka butadiene, isoprene, aromatic hydrocarbons, a pēlā aku. Hiki ke hoʻohana ʻia ma ke ʻano he solvent no ka hoʻōla ʻana i ka acetylene mai ke kinoea kūlohelohe a i ʻole ke kinoea naphtha thermal cracking māmā, a hiki i ka maʻemaʻe o ka hoʻōla ʻana i ka acetylene i hoʻopaʻa ʻia ke piʻi i 99.7%; ma ke ʻano he extractant no ka hoʻokaʻawale ʻana a me ka hoʻōla ʻana i ka butadiene maʻemaʻe kiʻekiʻe mai nā hydrocarbons C4 i haki ʻia, hiki i ka helu hoʻōla ke piʻi i 97%. %, ʻo ka maʻemaʻe o ka butadiene i hoʻōla ʻia he 99.7%, a hoʻohana ʻia ia ma ke ʻano he extractant no ka hoʻōla ʻana i ka isoprene maʻemaʻe kiʻekiʻe i ka haki ʻana o nā hydrocarbons C5, a hiki i ka maʻemaʻe hoʻōla o ka isoprene i 99%; i ka wā e hoʻohana ʻia ai ma ke ʻano he extractant no nā hydrocarbons aromatic, he solubility kiʻekiʻe no nā hydrocarbons aromatic. Me ke kaomi mahu haʻahaʻa, haʻahaʻa ka helu pohō o ka extractant a kiʻekiʻe ka helu hoʻōla o nā aromatics.

3. Papa Reagent: Degreasing, degreasing, dewaxing, polishing, prevention rust, paint stripping, etc. i nā ʻoihana e pono ai ka kaohi koʻikoʻi o nā ions metala a me nā microparticles i nā kaapuni i hoʻohui ʻia, nā disks paʻakikī, etc. Hoʻomaʻemaʻe ʻana i nā mea hana pololei, nā mea LCD liquid crystal, nā papa kaapuni i paʻi ʻia PCB, nā disks paʻakikī; a me nā mea hoʻoheheʻe i hana ʻia ma ka ʻoihana lāʻau lapaʻau e like me ka wai membrane hana kidney artificial, ka wai membrane desalination wai kai, etc.
