Cov khoom siv tshuaj
Tsis muaj xim pob tshab oily kua nrog me ntsis tsw ntawm amine.Nws tuaj yeem cuam tshuam nrog dej, cawv, ether, ester, ketone, halogenated hydrocarbon, aromatic hydrocarbon.
saib tag
N-methyl pyrrolidinone rau luv luv, molecular mis: C5H9NO, Lus Askiv: 1-methyl-2-PyrrolidinOne, tsos yog xim tsis muaj xim rau lub teeb daj pob tshab kua, nrog me ntsis ammonia tsw, mismisble nrog dej nyob rau hauv ib qho kev faib ua feem, soluble nyob rau hauv ether, acetone thiab ester, halogenated hydrocarbon, aromatic hydrocarbon thiab lwm yam organic solvents, Yuav luag tag nrho tov nrog tag nrho cov kuab tshuaj Chemicalbook, boiling point 204 ℃, flash point 91 ℃, hygroscopic, ruaj khov khoom, tsis muaj corrosion rau carbon steel, txhuas, me ntsis corrosive rau tooj liab.Nws muaj qhov zoo ntawm cov viscosity tsawg, zoo tshuaj thiab thermal stability, siab polarity, tsis tshua muaj volatility, infinite miscibility nrog dej thiab ntau organic solvents, thiab lwm yam. Cov khoom no yog ib tug micro tshuaj, qhov tso cai txwv concentration nyob rau hauv cov huab cua yog 100PP.
Kev siv tseem ceeb
(1.) Muaj qib:
Lubricating roj refining, lubricating roj antifreeze tus neeg saib xyuas, syngas desulfurization, hluav taws xob rwb thaiv tsev cov ntaub ntawv, ua liaj ua teb herbicides, tshuaj tua kab additives, PVC tail gas rov qab, qib high-qib coatings, number case, pigment ntau lawm additives thiab dispersants.Piv txwv li, siv los extract aromatics hauv lubricating roj kom ua tiav lub hom phiaj ntawm refining lubricating roj;Vim tias muaj ntau dua solubility ntawm NMP resin, raws li cov kuab tshuaj rau kev ua cov khoom siv tau tshwj xeeb hauv kev tsim cov coatings, pleev xim rau hauv pem teb, kua roj vanish, composite txheej zaj duab xis, integrated circuit enameled hlau rwb thaiv tsev cov ntaub ntawv, fiber ntau fabrics thiab adhesives thiab lwm yam khoom.
(2.) Qib Qib:
Extraction thiab rov qab los ntawm cov ntaub ntawv organic yooj yim, xws li acetylene extraction thiab butadiene, isoprene, aromatics thiab lwm yam extraction.Nws tuaj yeem siv los ua cov kuab tshuaj kom rov qab tau acetylene los ntawm cov nkev roj lossis lub teeb naphtha pyrolysis roj.Raws li cov extractant rau kev sib cais thiab rov qab los ntawm high-purity butadiene los ntawm tawg C4 hydrocarbon, tus nqi rov qab yog 97%, thiab purity ntawm recovered butadiene yog 99.7%.Raws li ib tug extractant rau rov qab ntawm high-purity isoprene los ntawm cracking C5 hydrocarbon, lub rov qab purity ntawm isoprene yog 99%.Vim nws cov solubility siab thiab tsis tshua muaj zog siab rau aromatics, tus neeg sawv cev extraction poob tus nqi qis thiab rov qab tus nqi ntawm aromatics yog siab.
(3.) Qib Reagent:
Integrated Circuit Court, hard disk thiab lwm yam yuav tsum tau nruj tswj ntawm cov hlau ions thiab hais txog kev lag luam ntawm deoiling, degreasing, dewaxing, polishing, xeb tiv thaiv, xim, xws li photoresist tshem tawm kua, IC semiconductor kev lag luam precision instruments, LCD kua siv lead ua cov ntaub ntawv, PCB luam tawm Circuit Board, hard disk tu;Raws li cov khoom siv rau lub raum ua haujlwm membrane kua, seawater desalination membrane kua thiab lwm cov kuab tshuaj uas tsim los ntawm kev lag luam kws tshuaj.
