3. Daim ntawv thov hauv kev lag luam khoom noj khoom haus
Hauv kev lag luam khoom noj khoom haus, HPMC tau siv dav ua cov tuab, emulsifier, stabilizer, thiab lwm yam, thiab feem ntau yog siv hauv:
Thickener thiab emulsifier: HPMC tuaj yeem txhim kho cov zaub mov, xws li hauv cov kua zaub thiab lwm yam khoom qab zib thiab emulsifier kom tswj tau qhov ruaj khov thiab saj ntawm cov khoom.
Cov Khoom Noj Khoom Siv Txheej: HPMC kuj tseem siv tau rau cov txiv hmab txiv ntoo, tshuaj, thiab cov tshuaj kho mob, uas tsis tuaj yeem tsuas yog txuas lub ntsej muag.
Cov zaub mov qis-muaj calorie: hauv kev tsim qee cov khoom noj muaj txiaj ntsig tsawg, HPMC tuaj yeem hloov cov roj uas xav tau los muab viscosity uas yuav tsum tau muab viscosity uas yuav tsum tau muab cov ntsiab lus calorie.
4. Daim ntawv thov hauv kev lag luam tshuaj pleev ib ce
HPMC yog siv los ua cov ntaub tuab, stabilizer thiab gelling tus neeg sawv cev hauv cov tshuaj pleev ib ce kev lag luam, ntxuav, zawv plaub hau, plaub hau daj thiab lwm yam khoom. Cov haujlwm tshwj xeeb suav nrog:
Thickening thiab gelling: hauv tshuaj pleev ib ce, HPMC tuaj yeem ua kom zoo siv, tswj cov ruaj khov lossis cov kua pleev, thiab tiv thaiv stratification.
Txhim kho kev sib txawv ntawm daim tawv nqaij: HPMC tuaj yeem muab txoj kev xav zoo rau ntawm daim tawv nqaij hauv qee cov khoom tu tawv nqaij, nce kev nplij siab thaum thov.
Hydration: HPMC muaj cov khoom muaj zoo moisturizing, tuaj yeem nqus thiab tso dej, thiab feem ntau pom nyob hauv cov dej noo, cov tshuaj ntxuav kom ntsej muag thiab lwm yam khoom.
5. Daim ntawv thov hauv cov tshuaj txhua hnub
HPMC kuj tseem siv tau siv tshuaj lom zem txhua hnub, tshuaj ntxhua khaub ncaws, softeners, etc. hauv cov khoom no, HPMC tuaj yeem:
Thickening thiab txhim kho kev ntxuav cov txiaj ntsig: hauv cov khaub ncaws tshuaj ntxuav cov khaub ncaws, hpmc ua cov ntaub ntawv zoo nkauj thiab muaj kev ruaj khov ntawm cov khoom thiab txhim kho cov nyhuv ntxuav.
Ua npuas ncauj ua npuas dej: Nws tuaj yeem txhim kho kev ua npuas ncauj ua npuas dej kom ntseeg tau tias cov npaus tsis ploj yooj yim thaum lub sijhawm ntxuav.
