Incazelo
I-N-Methyl-2-pyrrolidone iyi-solvent ye-aprotic enezinhlobo eziningi zezicelo: ukucubungula i-petrochemical, ukumbozwa kwendawo, udayi kanye nezingxenye, amakhemikhali okuhlanza ezimbonini nasekhaya, kanye nezindlela zezolimo nezemithi. Ngokuyinhloko iyacasula, kodwa futhi ibangele amacala amaningana e-contact dermatitis enkampanini encane ye-electrotechnical.

Ukusetshenziswa
Ukusetshenziswa
I-N-Methyl-2-pyrrolidone (NMP) iyi-solvent ye-polar aprotic enezinzuzo zobuthi obuphansi, iphuzu lokubila eliphezulu, i-solvency evelele, ukukhetha okunamandla kanye nokuqina okuhle.
Isetshenziswa kabanzi ekuhlanzeni i-aromatic hydrocarbon extraction, i-acetylene, i-olefins, kanye ne-diolefins.
Isetshenziswa ekuhlanzeni kwezimboni, futhi isebenza njengesithako sokukhiqiza izibulala-zinambuzane, amapulasitiki obunjiniyela, izembozo, imicu yokwenziwa, kanye nezifunda ezihlanganisiwe.
Ingasetshenziswa futhi njengesihlanzi sezimboni, isihlanzisi, udayi, amafutha kanye nesivimbeli sokubanda.
I-N-Methyl-2-pyrrolidone iyisithako esikhethekile, esisetshenziswa kabanzi ekukhipheni i-aromatics, ekuhlanzeni uwoyela ngokugcoba, ekukhuliseni i-acetylene, ekuhlukaniseni i-butadiene kanye nasekususeni i-sulfurization yegesi yokwenziwa.
Isetshenziswa ekususeni i-gas sulfurization, ekuhlanzeni uwoyela ngokugcoba, ekususeni uwoyela ngokugcoba, ekukhipheni i-olefin, kanye nasekunyibilikiseni ipulasitiki yobunjiniyela enganyibiliki.
Ingasetshenziswa ekubulaleni ukhula, ukuhlanza izinto zokuvikela ukushisa, amathuluzi okunemba embonini ye-semiconductor kanye namabhodi wesekethe, ukuphinda kusetshenziswe i-PVC exhaust, njengesihlanzi, isengezo sodayi kanye ne-ejenti yokusabalalisa.
Isetshenziswa ezindaweni zokuxhumana ukuze kusetshenziswe i-polymerization njengepulasitiki yobunjiniyela kanye ne-aramid fiber.
I-N-Methyl-2-pyrrolidone isetshenziswa njenge-polyvinylidene fluoride solvent kanye nezinto ezisizayo ze-electrode zamabhethri e-lithium ion.
izinga eliphezulu lokuhlanzeka kokutholwa kwe-ICP-MS.
Ukwenziwa kwe-peptide.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
