Pharmaceutical daim ntawv thov: vim lub siab molecular hnyav thiab cross-linked qauv ntawm cross-linked povidone, insoluble nyob rau hauv dej tab sis yuav sai sai txhawb nws network qauv kom nthuav thiab disintegrate thaum raug dej, nws yog dav siv raws li ib tug disintegrant rau ntsiav tshuaj hauv tshuaj. , thiab kuj yog siv dav hauv kev ncua kev kawm stabilizer, tus neeg sawv cev ua haujlwm rau cov khoom xyaw tshuaj, thiab tus neeg sawv cev rau cov tannins thiab polyphenols hauv cov tshuaj cog.

Daim ntawv thov zaub mov: PolyFilterTM molecules muaj amide bonds thiab adsorption ntawm hydroxide pawg ntawm polyphenol molecules los tsim hydrogen daim ntawv cog lus, yog li lawv tuaj yeem siv los ua kom ruaj khov rau npias, txiv hmab txiv ntoo / cawv txiv hmab, thiab dej haus cawv, txuas ntxiv lawv lub txee lub neej, thiab txhim kho lawv qhov tseeb, xim, thiab saj. Cov khoom yog muaj nyob rau hauv ob qho tib si pov tseg thiab regenerative specifications, thiab cov khoom pov tseg yog tsim rau cov lag luam me thiab nruab nrab; Cov khoom siv rov ua dua yuav tsum tau yuav cov khoom siv tshwj xeeb pom, tab sis lawv tuaj yeem siv tau thiab tsim nyog rau kev rov ua dua tshiab hauv cov breweries loj.
