Dipropyleneglycol CAS: 4254-15-3

Dipropyleneglycol (DPG) pom muaj kev siv dav hauv ntau yam lag luam vim nws cov khoom zoo. Hauv thaj chaw ntawm cov khoom siv tu tus kheej, DPG ua haujlwm ua cov kuab tshuaj thiab cov dej noo hauv cov qauv xws li tshuaj pleev, tshuaj pleev, tshuaj tsw qab, thiab cov khoom tu plaub hau. Nws lub peev xwm los yaj thiab ruaj khov ntau yam khoom xyaw thaum khaws cov dej noo ua rau nws muaj txiaj ntsig zoo rau kev txhim kho cov yam ntxwv ntawm kev hnov ​​​​​​thiab kev ua tau zoo ntawm cov khoom siv no. Ntxiv mus, DPG siv ua cov kua dej hauv cov tshuaj tsw qab thiab cov qauv tsw qab, pab faib cov tshuaj tsw qab thiab cov roj tseem ceeb kom zoo. Nws cov ntxhiab tsw qab thiab kev sib raug zoo nrog ntau yam tshuaj tsw qab thiab cov khoom xyaw ua rau nws tsim nyog siv rau hauv cov tshuaj tsw qab, colognes, cov tshuaj tsw qab cua, thiab cov khoom noj khoom haus. Hauv kev lag luam tshuaj, dipropyleneglycol siv ua cov kuab tshuaj thiab cov tshuaj sib koom ua ke hauv kev tsim cov tshuaj noj, tshuaj pleev, thiab tshuaj parenteral. Nws lub luag haujlwm cuam tshuam nrog kev txhim kho kev yaj thiab kev ruaj khov ntawm cov khoom xyaw tshuaj nquag, pab txhawb rau kev tsim cov txheej txheem xa tshuaj nrog kev txhim kho bioavailability thiab kev ua raws li tus neeg mob. Ntxiv mus, DPG ua haujlwm ua ib qho tseem ceeb hauv kev tsim cov tshuaj antifreeze rau kev lag luam thiab kev lag luam, qhov twg nws cov yam ntxwv tsis tshua muaj volatility thiab freeze-point depression pab tiv thaiv kev khov thiab corrosion hauv cov tshuab txias. Daim ntawv thov no tseem ceeb heev hauv tsheb, HVAC, thiab cov txheej txheem kev lag luam, kom ntseeg tau tias kev ua haujlwm zoo thiab txhim khu kev qha ntawm cov khoom siv hloov pauv cua sov. Tsis tas li ntawd, dipropyleneglycol yog siv ua cov kuab tshuaj hauv cov qauv number case, cov tshuaj pleev xim tshwj xeeb, cov khoom ntxuav, thiab cov kua hydraulic, qhov twg nws cov khoom solvency thiab viscosity txhawb nqa kev sib kis ntawm cov pigments, cov khoom xyaw nquag, thiab cov khoom siv ntxiv, pab txhawb rau kev ua tau zoo thiab kev ua haujlwm ntawm cov ntaub ntawv kev lag luam no. Hauv kev xaus, qhov versatility ntawm dipropyleneglycol ua rau nws siv tau ua cov kuab tshuaj, humectant, carrier fluid, thiab antifreeze agent thoob plaws kev saib xyuas tus kheej, tshuaj tsw qab, tshuaj, tsheb, thiab kev lag luam, qhia txog nws qhov tseem ceeb hauv kev txhawb nqa ntau daim ntawv thov thiab kev txhim kho ntau yam thev naus laus zis thiab cov khoom siv rau cov neeg siv khoom.
