NOTE:
1. The chemical composation is calculated on dry basis removed the adhesive moisture(except the loss on ignition).
2. The round-off number rule is stipulate as 5.2 of GB1250, and the rounded digit shall be consistant with the limiting values listed in the forms.
3. Normally, NaF/AlF3 ratio is between 1.8-2.9,any special requirements should be indicated in the contract.
4. Any requirements on the loss on igniton below 2.5% should be indicated in the contract.
PROPERTIES

High
Molecular Ratio

1. 4kinds of particle size are classified as follows:
(a)The Granular:1 - 10mm
(b)The Sandy:0.074-1mm(16 - 200mesh)
(c)The Powder:≤0.25mm(60mesh)
(d)The mixture of the above (a),(b),(c)
