Compare with the lg string method , encapsulated particles treated by dry impact method were well dispersed , processing time was shorter . the effect of size distribution of core particle was also discussed in dry impact method 對用lg攪拌磨和干式?jīng)_擊法制備的復(fù)合粒子進(jìn)行了比較,結(jié)果表明,用干式?jīng)_擊法制得的復(fù)合粒子,子粒子分散性好,且分布均勻、所需處理時(shí)間短、復(fù)合效果較佳。
