Note:
1. Sphere diameters of GA –385 are Φ1-2,Φ2-3,Φ3-5 respectively, and the relevant specific surface area and pore volume change with the baking temperature. The product can be manufactured according to customers' demands as well.
2.GA-383 is a microsphere carrier with the grain size of 45μm–90μm≥85%, and the relevant specific surface area and pore volume change with the baking temperature. The product can be manufactured according to customers' demands in the aspect of grain size.
3. The error range for the external size of the above-listed products is ±2.0mm. |
