O mea tau vailaau
Sua suau'u manino le lanu ma sina manogi amine.E mafai ona intersoluble i le vai, ava malosi, eter, ester, ketone, halogenated hydrocarbon, hydrocarbon aromatic.
vaaiga lautele
N-methyl pyrrolidinone mo le pupuu, fua mole: C5H9NO, Igilisi: 1-methyl-2-PyrrolidinOne, foliga e leai se lanu i moli samasama manino vai, ma sina manogi ammonia, mismisble ma le vai i soo se vaega, soluble i eter, acetone ma ester, hydrocarbon halogenated, hydrocarbon manogi ma isi solvents organic, Toeititi lava fefiloi atoatoa ma solvents uma Tusi Kemisi, vevela 204 ℃, mata moli 91 ℃, hygroscopic, mautu meatotino, leai se pala i le carbon uamea, alumini, teisi corrosive i apamemea.O loʻo i ai le lelei o le maualalo o le viscosity, vailaʻau lelei ma le faʻamautuina o le vevela, maualuga polarity, volatility maualalo, miscibility e le iʻu ma le vai ma le tele o solvents organic, ma isi mea.
Fa'aoga autu
(1.) Vasega Alamanuia:
Lubricating suauu faamamaina, lubricating suauu antiisaisa sui, syngas desulfurization, mea faaeletonika insulation, faatoaga herbicides, vailaau faaopoopo, PVC siʻusiʻu kasa toe faaleleia, coatings maualuga, vaitusi, gaosiga o pigmenti o additives ma dispersants.Mo se faʻataʻitaʻiga, faʻaaogaina e suʻe ai mea manogi i le suauu lubricating e ausia ai le faʻamoemoe o le faʻamamaina o le suauu lubricating;Ona o le sili atu solubility o le NMP resin, e pei o se solvent mo resin processing e mafai ona faʻaaogaina faapitoa i le gaosiga o coatings, vali fola, varnish, faʻapipiʻiina ata tifaga, fesoʻotaʻiga faʻapipiʻi enameled uaea insulation mea, fiber ie ma adhesives ma isi oloa.
(2) Tulaga masani:
Ave'esea ma toe fa'aleleia o mea fa'aola fa'avae, e pei o le acetylene extraction ma le butadiene, isoprene, aromatics ma isi fa'aputuga.E mafai ona faʻaaogaina e avea o se solvent e toe faʻaleleia ai le acetylene mai le kesi masani poʻo le kesi naphtha pyrolysis malamalama.I le avea ai o se suʻega mo le vavaeeseina ma le toe faʻaleleia o le butadiene mama maualuga mai le taʻeina o le C4 hydrocarbon, o le toe faʻaleleia o le 97%, ma le mama o le butadiene toe maua e 99.7%.I le avea ai o se suʻega mo le toe faʻaleleia o le isoprene maualuga-mama mai le taʻeina o le C5 hydrocarbon, o le toe faʻaleleia o le mama o isoprene e 99%.Ona o le maualuga o le solubility ma le maualalo o le mamafa o le ausa mo mea manogi, e maualalo le fua o le gau o sui sooupu ma maualuga le maualuga o le toe faʻaleleia o mea manogi.
(3.) Tulaga fa'afefe:
Integrated circuit, hard disk ma isi manaʻoga o le pulea saʻo o ion uʻamea ma vaega o le alamanuia o deoiling, degreasing, dewaxing, polesi, ele puipuiga, vali, e pei o photoresist aveesea vai, IC semiconductor alamanuia saʻo meafaifaʻaili, LCD mea tioata vai, PCB lolomi laupapa matagaluega, faamamaina tisiki malo;E fa'apea fo'i le sua sua ga'o ga'o gaogao, sua sua fa'amama vai ma isi vaifofo e gaosia e le falema'i.
