physical analysis:
1,outward appearance: colorless rhombic system white powder
2,whiteness:â‰Â¥96%
3,average grain diameter(um):0.9~1.2
4,sieves -odd thing (325mesh):tr
5,bet surface:12000+/-200
6,moisture: â‰Â¤0.22%
7,ph value: 7~8.5

9,absorbed oil:17.0~21.0
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.
packing:
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.
other explanations:
1,part of parameter will decides by the local network condition and the using condition.
