FA'ATULAGA:
Fa'amatalaga
O le N-Methyl-2-pyrrolidone o se vaila'au fa'aaprotic e tele ona fa'aoga: fa'agasologa o petrochemical, ufiufi o luga, vali ma mea fa'aopoopo, vaila'au fa'amamā fale ma fale gaosi oloa, ma fa'asologa fa'ato'aga ma vaila'au. O se mea e fa'aita ai le tino, ae ua mafua ai fo'i le tele o mataupu o le contact dermatitis i se kamupani eletise la'ititi.

Fa'aaogāga
Fa'aaogāga
O le N-Methyl-2-pyrrolidone (NMP) o se vaila'au fa'a-aprotic polar e iai ona lelei o le maualalo o le oona, maualuga le pupuna, maualuga le mafai ona totogi tupe, malosi le filifiliga ma le mautu lelei.
E faʻaaogaina lautele i le faʻamamāina o le faʻamamāina o le aromatic hydrocarbon extraction, acetylene, olefins, ma diolefins.
E fa'aaogaina i le fa'amamāina o fale gaosi oloa, ma e avea o se vaila'au fa'amama mo le gaosiga o vaila'au fa'asaina o iniseti, palasitika fa'ainisinia, ufiufi, alava fa'apitoa, ma matagaluega tu'ufa'atasi.
E mafai fo'i ona fa'aaogaina e fai ma fa'amamā fa'apisinisi, fa'asalalau mea, vali, fa'a'asu ma mea e tete'e ai i le 'aisa.
O le N-Methyl-2-pyrrolidone o se vaifofo sili ona lelei, e fa'aaogaina lautele i le fa'a'esea o mea manogi, fa'amamāina o le suāu'u fa'a'asu, fa'amauoa mai o le acetylene, vavae'esega o le butadiene ma le fa'amamāina o le kesi fa'a-synthesis.
E faʻaaogaina i le desulfurization o le kesi, faʻamamaina o le suauʻu faʻasusu, antifreeze o le suauʻu faʻasusu, faʻamama olefin, ma o se solvent mo le polymerization o palasitika faʻainisinia e le mafai ona solo.
E mafai ona faʻaaogaina i vailaʻau faʻamate vao, e faʻamamā ai mea e faʻamafanafana ai, meafaigaluega saʻo o le alamanuia semiconductor ma laupapa matagaluega, e toe faʻaaogaina ai le asu o le PVC, e fai ma vailaʻau fasimoli, faʻaopoopoga vali ma mea e faʻasalalau ai.
E faʻaaogaina i auala mo tali atu i le polymerization e pei o le inisinia palasitika ma le aramid fiber.
E fa'aaogaina le N-Methyl-2-pyrrolidone o se vaila'au fa'amama polyvinylidene fluoride ma se mea fa'aopoopo mo le eletise mo maa lithium ion.
tulaga maualuga le mama mo le iloa o le ICP-MS.
Mo le fa'aputuina o peptide.
Afifiina ma le Felauaiga
25KG/Palu po'o mana'oga o tagata fa'atau.
E patino i oloa masani ma e mafai ona tilivaina i le vasa ma le ea
Tausia ma teuina
Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Faleteuoloa e fa'amamago i le ea, fa'amago i le vevela maualalo, Vavae'ese mai mea e fa'aola ai le ea, 'asi.
