Polypropyleneglycol CAS: 25322-69-4

Polypropyleneglycol cov khoom sib txawv ua rau nws yog ib qho tseem ceeb hauv ntau qhov kev lag luam. Hauv kev lag luam tsheb, nws yog siv ua cov khoom xyaw tseem ceeb hauv kev tsim cov kua nres, cov kua hydraulic, thiab cov kua kis vim nws qhov kev ruaj khov thermal thiab oxidative zoo heev, cov khoom siv lubricating, thiab kev ua haujlwm kub qis, pab txhawb rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov tshuab tsheb. Hauv kev lag luam tshuaj, polypropyleneglycol yog siv ua cov khoom siv hauv cov tshuaj kom txhim kho kev yaj, bioavailability, thiab kev ruaj khov ntawm cov khoom xyaw tshuaj nquag. Nws qhov sib xws nrog ntau yam tshuaj ua rau nws yog ib qho khoom muaj nqis hauv kev npaj tshuaj, txhawb nqa kev tsim cov tshuaj zoo thoob plaws ntau qhov chaw kho mob. Ntxiv mus, cov polymer no pom kev siv dav hauv kev tsim cov khoom siv saib xyuas tus kheej xws li cov tshuaj pleev ib ce, cov khoom saib xyuas tawv nqaij, thiab cov qauv saib xyuas plaub hau. Nws cov khoom emollient thiab conditioning pab txhawb rau cov qauv thiab kev ua tau zoo ntawm cov khoom saib xyuas tus kheej, txhim kho lawv cov teebmeem moisturizing thiab smoothing rau kev siv tawv nqaij thiab kev saib xyuas plaub hau. Ntxiv mus, polypropyleneglycol ua haujlwm ua cov khoom xyaw muaj nqis hauv cov txheej txheem kev lag luam, suav nrog polyurethane ntau lawm, qhov twg nws lub luag haujlwm ua tus neeg nruab nrab pab txhawb rau kev tsim cov polyurethane polymers thiab ua npuas dej. Nws siv rau hauv urethane elastomers thiab coatings qhia txog nws qhov tseem ceeb hauv kev tsim cov khoom siv ua tau zoo rau kev siv hauv kev lag luam thiab kev lag luam. Tsis tas li ntawd, nyob rau hauv thaj chaw ntawm cov roj nplua nyeem thiab cov kua hlau ua haujlwm, polypropyleneglycol ua haujlwm ua cov kua dej ua los ntawm cov khoom siv hluavtaws, muab cov roj nplua nyeem zoo heev thiab thermal stability hauv ntau yam kev siv hauv kev lag luam. Nws siv rau hauv kev ua haujlwm hlau, cov roj iav, thiab cov roj nplua nyeem hauv kev lag luam txhawb nqa kev ua haujlwm zoo thiab lub neej ntev ntawm cov tshuab thiab khoom siv. Zuag qhia tag nrho, ntau yam kev siv ntawm polypropyleneglycol hauv tsheb, tshuaj, kev saib xyuas tus kheej, cov txheej txheem kev lag luam, thiab kev tsim khoom siv qhia txog nws qhov tseem ceeb ua cov polymer uas muaj ntau yam thiab tsis tseem ceeb, pab txhawb rau kev tsim cov khoom lag luam thiab cov ntaub ntawv ua tau zoo thoob plaws ntau yam kev lag luam.
