Hais txog Propylene Glycol
Propylene glycol (IUPAC lub npe: propane-1,2-diol) yog cov tshuaj tsis muaj xim thiab tsw ntxhiab kua siv tau ntau xyoo hauv ntau daim ntawv thov.Propylene glycol yog ib qho yooj yim organic compound uas muaj cov tshuaj formula C3H8O2.Nws yog miscible nrog ntau yam ntawm cov kuab tshuaj, suav nrog dej, acetone, thiab chloroform.
Kev siv tshuaj
Propylene glycol tuaj yeem siv rau hauv ntau hom kev lag luam thiab cov ntsiab lus raws li hauv qab no.
Propylene glycol yog ib qho tseem ceeb raw khoom ntawm unsaturated polyester, epoxy resin thiab polyurethane resin, uas suav txog li 45% ntawm tag nrho cov kev siv ntawm propylene glycol.Qhov no polyester unsaturated yog dav siv nyob rau hauv nto coatings thiab reinforced yas.
Propylene glycol reacts nrog fatty acid los tsim propylene glycol fatty acid ester, uas yog tsuas yog siv los ua zaub mov emulsifier hauv kev lag luam khoom noj khoom haus thiab kuj yog ib qho hnyav heev rau condiments thiab pigments.
Propylene glycol feem ntau yog siv los ua cov kuab tshuaj, softener thiab excipient hauv kev tsim cov tshuaj pleev thiab tshuaj pleev rau hauv kev lag luam kws tshuaj.Nws yog vim hais tias propylene glycol thiab txhua yam ntawm cov txuj lom muaj zoo solubility.
Propylene glycol kuj tseem siv tau los ua luam yeeb humidifier, tshuaj tua kab mob, roj nplua nyeem rau cov khoom siv ua zaub mov thiab hnyav rau cov zaub mov cim inks.
Cov tshuaj propylene glycol yog cov tshuaj tiv thaiv zoo.
