Kws Kho Mob Tshuaj HPMC
Kws Kho Mob Tshuaj HPMCHydroxyPropylulose yog xim dawb lossis mis nyuj tsis pub dhau 10%, cov dej ntws tsis muaj zog, ua kom cov dej kub, ua kom lub siab tawv, thiab sib sau ua hom phiaj colourcous , uas dhau los ua kev daws teeb meem thaum txias, thiab ua ib qho gel thaum ua kom sov. HPMC yog insoluble hauv ethanol, chloroform thiab ether. Nws yog soluble hauv cov kuab tshuaj sib xyaw ntawm cov methanol thiab methyl chloride. Nws tseem yog soluble hauv kev sib xyaw ua ke ntawm acetone, methyl chloride thiab isopropanol thiab qee lwm cov kuab tshuaj organic. Nws cov kua aqueous tuaj yeem zam ntsev (nws txoj kev daws teeb meem colloidal tsis tau rhuav tshem los ntawm ntsev), thiab cov ph ntawm 1% kev daws teeb meem yog 6-8. Cov mis nyuj molecular ntawm HPMC yog C8h15o8- (C10H18o6) -C815o, thiab cov txheeb ze cov roj av yog li 86,000.

Nta thiab cov txiaj ntsig:
HPMC muaj cov dej txi zoo heev hauv dej txias. Nws tuaj yeem yog yaj mus rau hauv kev daws teeb meem nrog me ntsis stirring hauv dej txias. Ntawm qhov tsis sib xws, nws yog qhov tseem insoluble hauv dej kub saum 60℃Thiab tsuas yog swell. Nws yog cov tsis-ionic cellulose ether. Nws cov kev daws teeb meem tsis muaj kev txiav txim ionic, tsis cuam tshuam nrog cov kav dej hlau lossis cov khoom siv ords, thiab tsis cuam tshuam nrog lwm cov txheej txheem npaj ua haujlwm; Nws muaj zog tiv thaiv-rhiab, thiab raws li cov qib hloov chaw nyob hauv cov qauv molecular nce, nws yog qhov tsis tshua muaj kev ua xua thiab muaj zog dua; Nws tseem yog metabolically inert. Raws li lub chaw muag tshuaj saib xyuas, nws tsis yog metabolized lossis nqus tau. Yog li, nws tsis muab cov cua sov hauv tshuaj thiab khoom noj. Nws yog tsawg-calorie, ntsev-dawb, thiab tsis yog ntsev-dawb rau cov ntshav qab zib. Kev ua yeeb tshuaj thiab cov khoom noj muaj cov khoom siv tshwj xeeb; Nws yog qhov ruaj khov rau cov kua qaub thiab alkalis, tab sis yog tias tus lej pH tshaj 2 ~ 11 thiab cuam tshuam los ntawm cov sijhawm sijhawm ntau dua lossis muaj lub viscos ntev yuav poob; Nws cov kua aqueous tuaj yeem muab cov kev ua si saum npoo av, uas qhia txog thaj av nruj thiab cuam tshuam cov txiaj ntsig. Nws muaj cov emulsification zoo nyob rau hauv ob-theem systemle, tuaj yeem siv los ua cov khoom siv khov kho thiab tiv thaiv kev tiv thaiv zoo; Nws cov kua aqueous muaj cov yeeb yaj kiab zoo tshaj plaws, thiab yog cov ntsiav tshuaj thiab ntsiav tshuaj zoo cov khoom siv zoo. Cov yeeb yaj kiab txheej tsim los ntawm nws muaj qhov zoo ntawm cov xim tsis muaj xim thiab tawv heev. Ntxiv cov glycerin kuj tseem tuaj yeem txhim kho nws cov plastonity.
