HydroxyPropyyl Methylcelluloseyog siv cov khoom siv dav siv. Tshwj xeeb tshaj yog nyob rau hauv kev siv ntawm cov hmoov putty. Muaj ntau cov khoom lag luam xws li: ntsev ua, thermal gelation, etcypropylulose kuj tseem nquag rau qee qhov teeb meem. Muaj peb qhov laj thawj rau cov teeb meem:
1. Kev siv ntawm hydroxypropyl methylcellose
2, yog tus nqi ntawm cov khoom siv hauv paus
3. Nws yog ib qho kev ua ke tsim nyog ntawm cov lim dej hauv cov qauv
Piv txwv, cov qauv viscosity ntawm hydroxypropylulose yog li cas yog vim li cas ntawm cov khoom siv viscelylropen yuav tsum tsis txhob loj dhau, tsis siab tshaj 6%. Tus muab tub lim rau cov tub lim rau feem ntau siv 325 mesh conventional muab lo, thiab thaum nws tshaj 600 mesh, kev tsim kho yuav muaj cuam tshuam cuam tshuam. Nco ntsoov tias cov xwm txheej saum toj no yuav tsum daws cov teeb meem ntawm batch tsis zoo scraping.
