Keeping a particle colloidal before use may be an effective method of forming a catalyst material as it can be easily spray-dried or mixed with other materials for extruded catalyst particles.
由于颗粒可以容易地被喷雾干燥或与其他用于挤压成型催化剂颗粒的材料混合，因此在使用前使颗粒保持为胶体是形成催化剂材料的有效方法。
Make sure that base paste and catalyst are mixed completely and are extruded in a uniform color.
确保基质膏剂和催化剂膏剂混合充分，而且压出时颜色均一。
