Cov khoom siv tseem ceeb ntawm HPMC yog kwvlam:
Refined Paj Rwb, Methyl chloride, Propylene Oxide, lwm cov ntaub ntawv raw, caustic dej qab zib, acid, isopropanol, thiab lwm yam.
Dab tsi yog qhov tseem ceeb ntawm hydroxypropyl methylculose hauv cov hmoov putterty, thiab seb puas muaj cov tshuaj tua kab mob organic?
HPMC ua si peb lub zog ntawm thickening, dej tuav thiab tsim hauv cov hmoov ua kom muaj hmoov.
Thickening: methylcellulose tuaj yeem muaj cov nplaim ntab kom tswj cov kev sib tw thiab kev ua haujlwm zoo sib xws thiab tiv thaiv ntws.
Dej khaws cia: Sab hauv phab ntsa hmoov dries maj mam, thiab ntxiv calcium txiv qaub yog xav txog hauv kev siv dej.
Kev tsim kho vaj tse muaj kev tsim kho: me me cellulose muaj cov nyhuv lubricating, uas tuaj yeem ua rau cov hmoov puty muaj cov qauv tsim khoom zoo. HPMC tsis koom nrog txhua yam kev hloov tshuaj lom tab sis tsuas yog hauv kev ntxiv. Tso cov hmoov txhuas, ntawm phab ntsa, vim tias muaj cov tshuaj tshiab hloov pauv, cov hmoov txhuas los ntawm cov hmoov, thiab siv tshuaj ntsuab (calcium carbonate) tau tsim tawm. Lub ntsiab ntawm cov calcium Fly tshauv yog: Ca (Oh) 2, CAO thiab ib qho me me ntawm cov hmoov av tshauv
Vim li cas cov pob zeb nplaum siv siab-viscosity HolroxyPropyloos Hlau Metlyly TheylingS, thiab nws zoo heev hauv cov xis qab cug thiab kua nplaum. Dej khaws thiab adhesion. Nws muaj qhov ntub dej tau zoo heev, cohesive, thickesening, pulsify, dej-khaws cov khoom, thiab nws impermability rau roj. Danzhai HydroxyPropyl methylropyf cellulose tus neeg saib xyuas cov khoom siv ntau ntawm cov dispersants thiab stabilizers. Ionic CMC yog siv nyob rau hauv hluavtaws xab npum spinning. Tsis tas li dav siv nyob rau hauv cov khoom siv hluavtaws, petrochemical, ceramics, ntawv, tawv, khoom noj thiab tshuaj pleev zaub mov thiab tshuaj pleev zaub mov thiab tshuaj pleev zaub mov thiab tshuaj pleev cov khoom noj.
