Khoom Siv Khoom Siv Tshuaj:
1.Nws muaj cov tshuaj lom neeg ntawm cawv thiab ethers thiab tuaj yeem tsim esters nrog phthalic acid, ricinic acid thiab oleic acid.
2.Stability: ruaj khov
3. Cov tshuaj txwv tsis pub:Acetyl chloride, acid anhydride, muaj zog oxidizing tus neeg sawv cev
4.Cov xwm txheej kom tsis txhob raug huab cua: Cua thiab lub teeb
5.Polymerisation txaus ntshai:Tsis yog polymerisation
Khoom siv:
1.Nws yog siv los ua hnyav rau roj, nitrocellulose, hluavtaws cob, cawv soluble dyestuff thiab ethyl cellulose; siv los ua kom qhuav sai sai rau cov kua roj vanish thiab txheej txheej diluent hauv kev lag luam txheej; siv los ua tus neeg saib xyuas thiab qib tus neeg sawv cev hauv kev lag luam luam ntawv thiab dyeing; siv los ua additive hauv kev lag luam roj; siv los ua dyeing auxiliaries hauv kev lag luam textile; siv los ua intermediate hauv organic synthesis. Diethylene glycol monomethyl ether feem ntau yog siv los ua cov kuab tshuaj kub npau npau rau number case, dye, resin, cellulose thiab xim, thiab tuaj yeem muab ntxiv rau hauv cov xim kom nws yooj yim rau ntws, txhuam thiab leveling, thiab tuaj yeem siv los ua cov tshuaj tua kab rau hydrocarbon. , ib qho nruab nrab rau kev npaj ntawm ester derivatives hauv kev lag luam organic synthesis thiab cov tshuaj reagent hauv analytical chemistry. Polyethylene glycol monomethyl ether tuaj yeem siv los ua dej nres.
2.Nws tuaj yeem siv los ua cov kuab tshuaj ntawm cov dyestuff, luam ntawv number case, cortisone, thiab lwm yam.
3.Widely siv raws li hnyav thiab diluent ntawm nitrofibre xim, kua roj vanish, enamel, thiab lwm yam.; inactive diluent ntawm adhesive; Cov kuab tshuaj ntawm txhua yam roj thiab cov rog, lignin, nitrocellulose, cellulose acetate, cawv-soluble dyestuffs, luam ntawv number case thiab hluavtaws resin li zoo li dispersant tshuaj tua kab, tawv kho tus neeg saib xyuas, plasticizer, brightener, thiab intermediate rau organic synthesis.
4.Siv ua kuab tshuaj.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Kev ntim khoom yuav tsum raug kaw, tsis sib cuag nrog huab cua.
2.Nws yuav tsum tau muab cais los ntawm oxidising cov neeg ua haujlwm, cov kua qaub, thiab lwm yam, thiab yuav tsum tsis txhob sib xyaw. Yuav tsum tsis txhob khaws cia rau hauv qhov ntau lossis ntev.
3.Txhim kho qhov tsim nyog ntau yam thiab cov khoom siv tua hluav taws. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
