EipponCell HPMC YB 5200MS, hydroxypropyl methylcellulose siv hauv cov khoom siv niaj hnub, yog cov hmoov dawb uas tsis muaj ntxhiab thiab tsis qab.Thaum yaj tag nrho hauv dej, nws tsim cov pob tshab thiab tuab colloidal tov.Nws tuaj yeem yooj yim ntxiv rau cov dej txias yam tsis tas yuav tsum tau yaj ua ntej, ua rau nws yooj yim thiab siv tau zoo.Nws nthuav tawm muaj zog foaming thiab detergency zog thaum muab cov thickening zoo.
Cov tshuaj aqueous ntawm HPMC rau kev siv txhua hnub yog qhov tseeb, muab cov teeb pom kev zoo siab thiab cov dej tuav tau tsawg kawg yog 97%.Nws ua haujlwm raws li emulsifier, thickener, homogenizer, thiab kev tiv thaiv colloid hauv cov khoom ua kua emulsified.Nws disperses, suspends, thiab stabilizes tshuaj zoo.Thaum muab tso rau hauv cov kua detergents, nws imparts ib tug siab sib xws, zoo heev transparency, tsis-stringiness, thiab tawm tsis muaj slippery seem ntawm tes tom qab ntxuav.Tsis tas li ntawd, rinsing yuav nyuaj.Nws ua haujlwm ua tus neeg sawv cev pabcuam zoo tshaj plaws rau cov khoom siv hluavtaws, cov tshuaj ntxuav tais diav, tshuaj zawv plaub hau, tshuaj pleev plaub hau, khoom tu tawv nqaij, thiab xab npum.
Nyob rau hauv cov txheej txheem ntxuav, HPMC tiv thaiv cov av los ntawm reattaching, txhim khu kev yooj yim ntawm xab npum, thiab pab txhawb kev ua thiab nias.
