摘要
论述先对硅灰石粉进行预处理，然后用三氧化铝等包膜剂对其进行气流包膜处理。试验结果表明，白度，消色力和分散性等都有明显提高，改性效果良好，气流色膜装置可行。
Airflow membrane-forming treatment with aluminium chloride as membraneforming agent was carried out after pretreatment of silica grey powder.Theresult shows that the whiteness,colour vanishing ability and dispersibility were improved,good modifying effect and the airflow membrane-forming equipment is andailable.
