JS-280
Cov nuj nqi thiab kev yuav tsum tau precipitated silica siv raws li thickening thiab abrasive neeg sawv cev nyob rau hauv cov tshuaj txhuam hniav yog described.It yuav muab yav tom ntej pseudoplasticity thiab thixotropy thaum lub thooj silica ntxiv nyob rau hauv lub formulation ntawm toothpaste.Its thooj nyhuv yog zoo kawg li thiab stabitity yog zoo thaum lub sij hawm cia nyob rau hauv ntev period.As ib tug abrasive neeg sawv cev, nws muaj qhov zoo ntawm muaj zog muaj peev xwm tu cov hniav, lub cev thiab tshuaj zog thiab zoo compatibility nrog rau lwm cov ingredients.It yog qhia tshwj xeeb uas taw tes qhia tawm hais tias cov precipitated silica nrog tsawg abradability thiab tsawg refractivity yog haum rau ua tus cov me nyuam-siv thiab pob tshab cov tshuaj txhuam hniav.
