專利匯可以提供Method of dispersing secondary particles of hydrated calcium silicate專利檢索,專利查詢,專利分析的服務(wù)。并且PURPOSE: Secondary particles of hydrated calcium silicate are treated with an acid to produce primary particles of hydrated calcium silicate used to reinforce resins.
CONSTITUTION: Secondary particles of hydrated calcium silicate are added to water containing 1/200W1/5mol, per mole of the calcium, of an acid such as hydrochloric or formic acid and stirred at high speeds to decompose the secondary particles, filtered, washed with water and dried. Thus, the secondary particles of hydrated calcium silicate with a shape of ball or chestnut burr are decomposed and the resultant dispersion well disperses in a resin to show the same effect as needle or plate crystals of hydrated calcium silicate, resulting in reinforcing the resin efficiently.
