Cov khoom

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 N-methylpyrrolidone nrog cov qib sib txawv thiab cov lus qhia tshwj xeeb tau teev tseg raws li hauv qab no: 1. Cov qib muaj: lubricating roj refining, lubricating roj antifreeze, syngas desulfurization, hluav taws xob rwb thaiv tsev cov ntaub ntawv, tshuaj tua kab mob, tshuaj tua kab additives, PVC tail gas rov qab, pab thiab dispersants rau zus tau tej cov qib high-qib coatings, inks, pigments, thiab lwm yam. Piv txwv li, nws yog siv los extract aromatic hydrocarbons nyob rau hauv lubricating roj kom ua tiav lub hom phiaj ntawm refining lubricating roj;Vim yog lub siab solubility ntawm NMP rau resin, nws tuaj yeem siv los ua cov kuab tshuaj rau kev ua haujlwm hauv kev tsim cov coatings, pleev xim rau hauv pem teb, varnishes, composite coating films, integrated circuit enameled wires Rwb thaiv tsev cov ntaub ntawv, fiber ntau 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 qis vapor siab, tus neeg sawv cev rho tawm poob qis qis thiab qhov muaj ntxhiab hydrocarbon rov qab tus nqi siab.3. Reagent qib: kev sib xyaw ua ke, hard disks thiab lwm yam kev lag luam uas yuav tsum tau tswj nruj ntawm cov hlau ions thiab cov khoom xeb, xim stripping, thiab lwm yam, xws li photoresist tshem tawm kua, ntxuav cov cuab yeej precision hauv IC semiconductor kev lag luam, LCD kua siv lead ua cov ntaub ntawv, PCB luam tawm Circuit Board, hard disks;thiab tsim cov khoom siv raum ua haujlwm membrane kua, seawater desalination membrane kua thiab lwm yam kev lag luam kev lag luam cov kuab tshuaj.
