摘要： 對(duì)涂布級(jí)高嶺土進(jìn)行顆粒分級(jí),結(jié)果表明粒度分布是影響高嶺土漿料黏度的一個(gè)重要因素,高嶺土顆粒中超細(xì)顆粒(0-0.5μm)和較大顆粒(+2.0μm)的大量存在,會(huì)造成高嶺土漿料黏度的升高,且不利于漿料懸浮液的穩(wěn)定性。并確定了兩個(gè)能有效降低漿料黏度的粒度組成。 The result of tests of classification of coating kaolin proved that granularity distribution is an important factor for the viscosity of kaolin.A great deal of fine particles and bigger particles increase the viscosity of the kao- lin suspensions and make against the stability of the suspensions,and two different granularion distribution which can reduce the viscosity of kaolin suspensions effectively are determined.
