1,Outward appearance: Colorless rhombic system white powder
3,Average grain diameter(um):0.9~1.2
4,Sieves -odd thing (325mesh):Tr
7,PH value: 7~8.5
Product examination method:
1,grain-size distribution: determination by GSL-101B I laser pellet distributed measuring apparatus.
2,even diameter particle size: Obtains the particle size intermediate quantity by the grain-size distribution.
3,BET Surface: Transforms by the average grain diameter, the unit is the 1g powder relative area.
4,325MESH remnant remainder: Puts the 1000g test specimen in 325mesh filters by the aqueous method ,calculates its residual proportion.
5,Postulate specific gravity: Puts the 50g test specimen in 100C.C graduated cylinder which has the scale division, highly falls from 5cm to floor about 150 times,then measure the definite value.
6,whiteness: measure by the Shanghai SBDY-1 whiteness apparatus.
7,moisture content: JLS-K5101 110 °C 2 hours.
8,PH value: measured by PHS-3C precise PH apparatus.
9,Absorbed Oil value: Use method of the JLS-K5101, joins the linseed oil then titrate, determines when becomes massive.
20 ~ 50 kilograms paper bags or compound bag, half ton bag or ton bag packing, also may act according to the customer request and specification making to order.
1,Part of parameter will decides by the local network condition and the using condition.
