Lub luag haujlwm ntawm hydroxypropyl methyl cellulose hauv cult txaws

HydroxyPropyl methyl cellulose hauv cov capulle qhuav, cellulose ether ntxiv yog tsawg heev, tab sis tuaj yeem txhim kho kev ua yeeb yam ntawm kev ua tau zoo heev, tab sis kuj tuaj yeem txhim kho kev ua yeeb yam yog ib qho tseem ceeb ntxiv. Tam sim no, HydroxyPropyf methyl cellulose siv nyob rau hauv cov cellulose cellulose cellulose ether yog mas hydrothylropy ethere ether (HPMC). HydroxyPropyl methyl cellulose hauv cov colle capulose hauv cov laj thawj qhuav hauv dej khaws cia, thickening, txhim kho kev ua haujlwm ntawm kev tsim kho. HydroxyPropyyl methylcellose HPMC tsis koom nrog kev tshuaj tiv thaiv tshuaj, tsuas yog ua ib qho kev lav phib xaub. Putty hmoov ntxiv dej, ntawm phab ntsa, yog cov tshuaj lom neeg cov tshuaj tiv thaiv, vim tias muaj cov hmoov tshiab, thiab tom qab ntawd nws tsis tau tsim cov khoom siv tshiab (calcium carbonate). Lub ntsiab Cheebtsam ntawm cov hmoov av grey calcium yog: (Oh) 2,

Zoo siab ntawm hydroxypropal methylropeyl cellulose tuaj yeem sib xyaw ua ke, thiab ntim cov khoom ntub dej, thiab cov khoom siv plaster, thiab cov khoom siv plaster, thiab cov khoom siv plaster, thiab cov khoom siv plhaw kom meej, thiab cov khoom siv plaster, thiab cov khoom siv plaster, thiab cov khoom siv plaster, thiab cov khoom siv plhaw kom ntseeg tau, thiab cov khoom siv plhaw tag nrho Yog li ntawd, hauv kev siv kub lub caij ntuj sov, kom ua tiav cov txiaj ntsig kev ua haujlwm hauv HPMC, tsis pub dhau, tsis muaj zog, tab sis kuj tseem ua rau muaj teeb meem kev tsim kho. Raws li qhov ntsuas kub tsawg dua, cov dej uas tau ntxiv los ntawm HPMC tuaj yeem txo qis qis, thiab tib cov nyhuv retentely tuaj yeem ua tiav.
