Dipropylene glycol methyl ether yog cov organic hnyav nrog ntau yam kev lag luam thiab kev lag luam siv. Cov khoom lag luam feem ntau yog sib xyaw ntawm plaub isomers.
Siv los ua cov kuab tshuaj rau nitrocellulose, ethyl cellulose, polyvinyl acetate, thiab lwm yam.; raws li cov kuab tshuaj rau nitrocellulose, ethyl cellulose, polyvinyl acetate, thiab lwm yam, raws li ib tug hnyav rau cov xim thiab dyes, thiab raws li ib tug brake kua tivthaiv. Siv los ua cov kuab tshuaj rau luam ntawv number case thiab enamel, thiab tseem siv los ua cov kuab tshuaj ntxuav cov roj thiab cov roj ua haujlwm. Siv los ua tus neeg sawv cev sib txuas rau cov xim pleev xim dej (feem ntau sib xyaw);
Active cov kuab tshuaj rau cov xim pleev xim dej;
Cov kuab tshuaj thiab cov coupling tus neeg sawv cev rau tsev neeg thiab kev lag luam tshuaj ntxuav, roj thiab cov xim tshem tawm, cov tshuaj ntxuav hlau, cov tshuaj ntxuav tawv tawv;
Cov kuab tshuaj yooj yim thiab coupling cov neeg ua haujlwm rau cov kuab tshuaj raws li cov tshuaj ntsuam luam ntawv inks;
Coupling tus neeg sawv cev thiab hnyav rau vat dye fabrics;
Coupling tus neeg sawv cev thiab tus neeg saib xyuas ntawm daim tawv nqaij rau cov tshuaj pleev ib ce; stabilizer rau cov tshuaj tua kab ua liaj ua teb; coagulant rau hauv av brighteners.
Cov cheeb tsam thov
Txheej: Zoo solvency rau resins xws li acrylics, epoxies, alkyds, nitrocellulose resins thiab polyurethane resins. Tsawg vapor siab thiab qeeb evaporation tus nqi, ua tiav dej miscibility thiab zoo compounding zog.
Tus neeg saib xyuas: tsis tshua muaj qhov nro, tsis tshua muaj ntxhiab tsw thiab qis evaporation tus nqi. Zoo solubility rau ob qho tib si polar thiab non-polar tshuaj, nws yog ib qho kev xaiv zoo rau dewaxing thiab ntxuav hauv pem teb.
Qhov zoo
Cov khoom lag luam zoo, kom muaj nuj nqis txaus, kev xa khoom zoo, kev pabcuam zoo Nws muaj qhov zoo dua li cov amine zoo sib xws, ethanolamine, nyob rau hauv qhov siab dua yuav siv tau rau tib lub peev xwm corrosion. Qhov no tso cai rau cov refiners los txhuam hydrogen sulfide ntawm qis dua amine tus nqi nrog tsawg zog siv tag nrho.
