The surface reactivity of many nonblack fillers generally precludes strong bonding with this type of matrix . 許多非碳黑填料的表面反應性一般阻礙與該種基質(zhì)形成牢固的粘結(jié)。
Powders , especially ultra - fine powders , which have many advantages , such as fine particle size , large specific surface , high surface reactivity , are widely used 粉體特別是超細粉體,因具有粒子細,比表面積大,表面活性高等特點而得到廣泛應用。
