HPMC ua raws li cov thickener, stabilizer thiab emulsifier.Nws yog feem ntau siv rau hauv kev tsim cov khoom noj xws li cov kua ntses, hnav khaub ncaws thiab cov khoom ci.HPMC lub peev xwm los tsim cov gels ntshiab thiab cov yeeb yaj kiab ua rau nws tsim nyog rau cov ntawv thov uas qhov kev ntxhib los mos thiab cov tsos yog qhov tseem ceeb.Tsis tas li ntawd, nws cov khoom tuav dej pab txuas ntxiv lub neej txee ntawm qee yam khoom noj.
hauv kev tsim kho kev lag luam
HPMC yog siv ntau yam khoom siv hauv tsev.Nws feem ntau ntxiv rau cov khoom siv cement, nrog rau cov mortars, plasters thiab pobzeb nplaum, txhawm rau txhim kho kev ua haujlwm, tuav dej thiab adhesion.HPMC tseem tuaj yeem siv los ua tus hloov kho rheology los txhim kho qhov sib xws thiab kev ua haujlwm ntawm cov khoom siv hauv tsev.
Hauv kev lag luam tshuaj pleev ib ce thiab kev tu tus kheej
HPMC yog siv rau hauv cov khoom xws li cream, tshuaj pleev thiab tshuaj zawv plaub hau.Nws cov khoom tsim cov yeeb yaj kiab pab tsim kom muaj kev sib tw, txawm tias kev ntxhib los mos hauv cov qauv tshuaj pleev ib ce, thaum nws lub peev xwm tuav dej ua rau cov nyhuv moisturizing ntawm cov khoom tu tawv nqaij.
Lub cev thiab tshuaj lom neeg cov khoom ntawm HPMC tuaj yeem hloov kho los ntawm kev hloov kho yam xws li qib kev hloov pauv thiab qhov hnyav molecular thaum lub sijhawm tsim khoom.Qhov kev hloov pauv no tso cai rau HPMC tuaj yeem hloov kho kom tau raws li cov cai tshwj xeeb ntawm ntau daim ntawv thov.
Hydroxypropyl methylcellulose (HPMC) yog ib qho khoom siv polymer uas siv dav hauv kev lag luam sib txawv.Nws versatility, kev nyab xeeb, thiab muaj peev xwm hloov kho cov khoom ntawm ntau yam khoom ua rau nws muaj txiaj ntsig zoo hauv cov tshuaj, khoom noj, kev tsim kho, tshuaj pleev ib ce, thiab lwm yam.
