| 摘要 |
The present invention relates to a manufacturing method of silica gel and, more particularly, to a manufacturing method of silica gel by using a drying method via batch type fluidized drying to manufacture silica gel from silica hydrogel. Powder particles are formed into a suspension form from the bottom of a powder particle layer, and moisture in the powder particles is evaporated and separated. The silica gel manufactured according to the present invention exhibits a distribution of the diameter of holes having B/A of less than or equal to 0.5, and can alter and control BET specific surface area. |
