Khoom ntawm polypropylene glycol
Tsis muaj kob daj kua nyeem daj ua kua. Tsis-hloov pauv. Tsis-corrosive. Qhov hnyav phaus molecular ntawm cov khoom siv dav yog 400 ~ 2050. Cov roj molecular nyhav qis yog soluble hauv dej. Cov dej siab tshaj cov kua roj polymers tsuas yog me ntsis soluble hauv dej, soluble hauv cov roj, ntau hydrocarbons, thiab aliphatic cawv, ketones, esters, thiab cov zoo li. Hydroxyl pawg ntawm ob hnub kawg ntawm cov lwg me me tau esterified los ua mono- lossis di-esters. Nws cov monoester yog non-ionic surfactant thiab tseem tuaj yeem cuam tshuam nrog kev haus dej cawv kom tsim tau ethers. Nws yog cov kuab tshuaj rau cov roj zaub, cov tawv ntoo thiab cov roj av paraffin. Nws kuj tseem siv hauv kev npaj ntawm alkyd resins, emulsifiers, demulsifiers, tshuab roj thiab lub hnab yas. Nws tau los ntawm cov kab sib xyaw ntawm propylene oxide thiab propylene glycol nyob rau hauv qhov muaj qhov siab los yog kua qaub catalyst.
