Kev siv ntawm NMP

N-methylpyrrolidone (NMP) yog polar aprotic hnyav.Nws muaj tsawg toxicity, siab boiling point thiab zoo solubility.Qhov zoo ntawm kev xaiv muaj zog thiab kev ruaj ntseg zoo.Dav siv nyob rau hauv aromatic hydrocarbon extraction, purification ntawm acetylene, olefins thiab diolefins, cov kuab tshuaj rau polyvinylidene fluoride, electrode auxiliary cov ntaub ntawv rau lithium ion roj teeb, syngas desulfurization, lubricating roj refining, lubricating roj antifreeze, olefin extractant, nyuaj ntawm yas engineering. , cov tshuaj tua kab mob ua liaj ua teb, cov ntaub ntawv insulating, kev tsim hluav taws xob sib xyaw ua ke, kev tu cov cuab yeej precision hauv kev lag luam semiconductor, Circuit Court boards, PVC pa roj rov qab, ntxuav cov neeg ua haujlwm, dye auxiliaries, dispersants, thiab lwm yam. rau polymerization, xws li engineering plastics thiab aramid fibers.Nws kuj tseem siv tau rau hauv tshuaj tua kab, tshuaj thiab tshuaj ntxuav.Kev siv tseem ceeb ntawm cov qib sib txawv ntawm N-methylpyrrolidone tau teev tseg hauv qab no:

1. Muaj qib: lubricating roj refining, lubricating roj antifreeze, syngas desulfurization, hluav taws xob rwb thaiv tsev cov ntaub ntawv, kev ua liaj ua teb herbicides, tshuaj tua kab auxiliaries, PVC tso pa roj rov qab, auxiliaries thiab dispersants rau zus tau tej cov qib high-qib coatings, inks, pigments, thiab lwm yam. Piv txwv li, nws yog siv los rho cov ntxhiab hydrocarbons nyob rau hauv cov roj lubricating kom ua tiav lub hom phiaj ntawm refining lubricating roj;vim yog lub siab solubility ntawm NMP rau resin, nws yuav siv tau raws li ib tug hnyav rau resin thiab Chemicalbook yuav tsum tau siv nyob rau hauv lub tsim ntawm coatings, pem teb xim, varnishes, composite coatings, zaj duab xis-forming, integrated Circuit Court enameled hlau rwb thaiv tsev cov ntaub ntawv, fiber. fabrics thiab adhesives thiab lwm yam khoom.

2. Ordinary qib: extraction thiab rov qab los ntawm cov organic raw khoom, xws li acetylene concentration thiab extraction ntawm butadiene, isoprene, aromatic hydrocarbons, thiab lwm yam. Nws yuav siv tau raws li ib tug hnyav rau recovering acetylene los ntawm natural gas los yog lub teeb naphtha thermal cracking gas, thiab purity ntawm recovering concentrated acetylene tuaj yeem ncav cuag 99.7%;Raws li cov extractant rau kev sib cais thiab rov zoo siab-purity butadiene los ntawm tawg C4 hydrocarbons, tus nqi rov qab tuaj yeem ncav cuag 97%.%, lub purity ntawm recovered butadiene yog 99.7%, thiab nws yog siv raws li ib tug extractant rau recovering high-purity isoprene nyob rau hauv cracking C5 hydrocarbons, thiab lub rov qab purity ntawm isoprene mus txog 99%;Thaum nws yog siv los ua ib qho extractant rau aromatic hydrocarbons, nws muaj solubility siab rau aromatic hydrocarbons.Nrog tsawg vapor siab, qhov poob tus nqi ntawm extractant yog tsawg thiab tus nqi rov qab ntawm aromatics yog siab.

3. Reagent qib: Degreasing, degreasing, dewaxing, polishing, tiv thaiv xeb, xim stripping, thiab lwm yam hauv kev lag luam uas yuav tsum tau tswj nruj ntawm cov hlau ions thiab microparticles hauv kev sib xyaw ua ke, hard disks, thiab lwm yam. , PCB luam ntawv Circuit Court boards, hard disks;thiab cov kuab tshuaj uas tsim nyob rau hauv kev lag luam kws tshuaj xws li dag lub raum ua haujlwm membrane kua, seawater desalination membrane kua, thiab lwm yam.
