A two -fold smoothness of aluminum foil backing paper can be achieved by using dryer-adhesive P with surface sizing.
通过实验发现:选用贴缸剂P对铝箔衬纸湿纸页进行表面施胶,可以较大程度地提高铝箔衬纸的表面平滑度,贴缸剂P的用量为0。
In order to take concerted geological general survey,Improve the analyse sensitivity and the precisions of trace gold in the samples,use the reagent of "p",precipitate the silicic acid,reduce the ash content,in the mean time,it can reduce the obstacles.
为配合地质普查找矿,提高化探分散流样品中的微量金分析的灵敏度和准确度,采用“P”试剂即聚氧化乙烯沉淀可溶性硅酸,减少灰分,降低干扰,对两个标样做了分析,精密度RSD为7。
