Dab tsi yog hydroxypropyl methyl cellulose tseem ceeb cov khoom siv raw?

HydroxyPropy cellulose hauv Putty Hmoov, tus yuam sij yog dab tsi ua tau, Txawm yog cov organic chemistry?

HPMC nyob rau hauv Weety hmoov thickening, dej tuav thiab tsim peb lub zog.

Thickening: methyl cellulose tuaj yeem muaj cov nplaim ntab thiab aqueous daws los tswj kev ua haujlwm zoo thiab tiv thaiv kev txwv txaus.

Dej khaws cia: Sab hauv phab ntsa hmoov yog maj mam qhuav thiab cov txiv qaub calcium tau cuam tshuam hauv kev siv dej.

Kev tsim kho vaj tse muaj zog: Methyl cellulose muaj lubricating nyhuv, yog li ntawd uas putty hmoov muaj cov qauv ua kom zoo. HPMC tsis koom nrog txhua qhov kev hloov tshuaj lom neeg, tab sis tsuas yog ua kom tiav. Putty hmoov, ntawm phab ntsa, yog kev hloov tshuaj lom neeg vim tias muaj cov hmoov tshiab tawm, ua rau cov hmoov tshiab, thiab siv cov tshuaj tshiab (calcium carbonate) tau tsim tawm. Lub hauv paus tseem ceeb ntawm cov calcium Fly tshauv yog ca (hig) 2, CAO thiab ib qho me me ntawm cov dej hiav txwv tshauv ya mus tshauv, nws tsis koom nrog kev xav txog.

Dab tsi yog hydroxypropyl methyl cellulose tseem ceeb cov khoom siv raw?

Refined Paj Rwb, Chloromethane, Propylene Oxide, lwm cov ntaub ntawv raw, alkali, acid, yog toluene dej cawv, thiab lwm yam.

Ceramic pobzeb binder vim li cas siv viscosity hydulose, dab tsi nws muaj: hydrepropal cellulose, nyob rau hauv xis mas muaj dej ua kom zoo thiab coheseniven. Wettability zoo heev, kev faib tawm, coheseness, thickening, emulsification, dej tuav thiab ua yeeb yaj kiab tsim, thiab roj customility. Danzhai HydroxyPropyfropyl cellulose tus neeg sawv cev tsis sib haum thiab stabilizer nyob rau hauv ntau ntau. Ionic CMC yog siv nyob rau hauv hluavtaws xab npum spinning. Kuj tseem dav siv nyob rau hauv hluav taws xob cob, petrochemical, ceramic, ntawv, tawv, khoom thiab tshuaj pleev ib ce thiab lwm yam kev lag luam.
