1,2-Propylene Glycol CAS NO.57-55-6
Khoom Description
- 1,2 Propylene glycol yog ib qho nruab nrab ntawm cov kab mob bactericide difenoconazole thiab ib qho tseem ceeb raw khoom rau unsaturated polyester, epoxy resin, thiab polyurethane resin. Cov nyiaj hauv qhov no suav nrog kwv yees li 45% ntawm tag nrho kev noj ntawm 1,2 propylene glycol. Qhov no unsaturated poly Ester yog dav siv nyob rau hauv nto coatings thiab reinforced yas. 1,2 Propylene glycol muaj viscosity zoo thiab hygroscopicity, thiab tsis muaj tshuaj lom, yog li nws tau dav siv los ua cov dej noo noo, tshuaj tua kab mob, roj nplua nyeem thiab hnyav hauv cov khoom noj, tshuaj thiab tshuaj pleev ib ce. Hauv kev lag luam zaub mov, nws yog siv los ua zaub mov emulsifier; Nyob rau tib lub sijhawm nws yog ib qho hnyav hnyav rau seasonings thiab pigments.
- Cov txheej txheem rho tawm ntawm 1,2 propylene glycol belongs rau kev ua haujlwm ntawm kev sib cais tshuaj. Cov txheej txheem no siv cov yam ntxwv uas cov ntxhia acid ntsev yog ib qho yooj yim rau crystallize, thaum cov organic acid ntsev hauv propylene glycol fermentation broth tsis yooj yim rau crystallize. Ib qho tsim nyog ntawm inorganic acid yog ntxiv rau propylene glycol fermentation broth los hloov cov organic acid ntsev hauv fermentation broth nrog organic acids. Cov ntxhia hauv acid ntsev yog generated; lub fermentation broth yog concentrated, thiaj li hais tias cov ntxhia acid ntsev crystallizes, thiab yog cais los ntawm fermentation broth; cov concentrated fermentation broth ua propylene glycol, succinic acid, lactic acid, acetic acid, glycerol thiab 2,3-butane Cov sib tov ntawm cawv, nqus distillation ntawm cov sib tov kom tau cov khoom ntawm txhua feem. Hauv kev lag luam kws tshuaj, propylene glycol feem ntau yog siv los ua cov kuab tshuaj, softener thiab excipient rau kev tsim khoom ntawm ntau yam tshuaj pleev thiab tshuaj pleev. Vim nws zoo sib xws nrog ntau yam txuj lom, nws kuj yog siv los ua ib qho hnyav thiab softener rau cov tshuaj pleev ib ce.Propylene glycol kuj yog siv los ua luam yeeb moisturizer, antifungal agent, khoom noj khoom haus lubricating roj thiab zaub mov cim number case hnyav. Ib qho tshuaj aqueous ntawm propylene glycol yog cov tshuaj tiv thaiv zoo.
