Chaw tsim tshuaj paus zoo nqe n-methyl pyrrolidone (NMP) CAS: 872-50-4

Cov lus piav qhia luv luv:

N-methyl pyrrolidone tau raug xa mus rau AS NMP, cov qauv molecular: C5h9no Acetone thiab ntau yam tshuaj kuab cua organic xws li esters, halogenated hydrocarbons, muaj ntxhiab Hydrocarbons, yuav luag txhua yam sib xyaw nrog txhua cov kuab tshuaj, rhaub cov tshuaj, tsis yog-flacoscopicity, tsis yog-corrosive rau cov steel hlau, txhuas, tooj me ntsis corrosive. NMP muaj qhov zoo ntawm cov viscosity qis, tshuaj lom neeg zoo, thiab tsis tshua muaj qhov tsis sib xws nrog dej thiab ntau cov kuab tshuaj organic. NMP yog micro-tshuaj, thiab cov kev txwv uas tau tso cai hauv huab cua yog 100ppm.

Cov ntawv thov ntawm NMP

N-methylprolidone (NMP) yog polar apvor hnyav. Nws muaj cov tshuaj lom tsawg, muaj kev kub siab thiab zoo nkauj sterility. Qhov zoo ntawm kev xaiv muaj zog thiab muaj kev ruaj khov zoo. Dav siv nyob rau hauv cov tshuaj tua kab mob hydocarbon, Olgins thiab DiCleFins tshuaj, lubricating roj ua kom zoo, cov tshuaj lom neeg nyob rau hauv cov polymerization ntawm encharies plastics , kev ua liaj ua teb ua liaj ua teb, Insulating cov ntaub ntawv, kev sib xyaw ua ke ntau lawm Circuiting, ntxuav cov chaw ua haujlwm sib luag, muab tshuaj txhuam cov pa taws, thiab lwm yam. Nws tseem yog siv rau polymers thiab ib nrab rau polymerization, xws li raws li engineering plastics thiab aramid fibers. Nws kuj tseem siv tau rau hauv cov tshuaj tua kab, cov tshuaj thiab cov tshuaj ntxuav tu. Lub ntsiab siv kev siv cov qib sib txawv ntawm n-methylpyrrolidone muaj nyob hauv qab no:

1. Kev lag luam roj: Lubricating roj ua kom zoo, roj nplua, tshuaj tua kab, tshuaj tua kab, tshuaj tua kab, pigments, thiab lwm yam rau Piv txwv li, nws yog siv los rho cov ntxhiab Hydrocarbons hauv lubricating roj kom ua tiav lub hom phiaj ntawm cov roj refinating; Vim tias lub solubility siab ntawm NMP rau Resin, nws tuaj yeem siv los ua cov kuab tshuaj, varosises, ua yeeb yaj kiab enameled xaim hluav taws xob cov ntaub ntawv, fiber ntau ntaub thiab cov nplaum thiab lwm yam khoom.

2. QUPT: EXRAGRION thiab rov qab los ntawm cov khoom siv raw raws li cov kuab tshuaj pleev kom zoo, thiab lwm yam. Lub teeb Naphhaus tawg tawg roj, Thiab cov kev coj dawb huv ntawm kev rov ua haujlwm acetylene tuaj yeem ncav cuag 99.7%; Raws li ib qho extractant rau kev sib cais thiab rov ua kom rov zoo dua C4 Hydrocarbons, tus nqi rov qab tuaj yeem ncav cuag 97%. %, lub purity ntawm rov qab butadiene yog 99.7%, thiab nws tau siv ua ib qho kev rov qab ua rau muaj kev sib cav sib ceg ntawm isoprene tau nce 99%; Thaum nws tau siv ua ib qho extractant rau cov ntxhiab hydrocarbons, nws muaj cov solubility hydrocarbons. Nrog cov vapor tsawg, cov nqi poob ntawm cov extractant yog tsawg thiab rov ua dua tus nqi ntawm cov AROMATS yog qhov siab.

3. Reagent qib: degring, degreasing, polishing, xim stripping ntawm cov twj paj nruag, thiab lwm yam. , PCB luam tawm cov laug cam, nyuaj disks; thiab cov kuab tshuaj tsim nyob rau hauv kev lag luam kws tshuaj xws li cov khoom siv dag lub raum ua dej, dej hiav txwv weartination membrane dej, thiab lwm yam.
