HK-111M Papermaking Type Wollastonite Power

Description:

Wollastonite is a natural chain-type calcium metasilicate mineral, its molecular formula is CaSiO3 or Ca3[Si3O9].Wollastonite can still maintain good fiber structure after processing and crushing. Because of similar characteristics with plant fiber, it can be used to replace part of plant fiber to produce paper in order to reduce the cost.

The study confirmed that with the use of wollastonite composite fiber, the pollution source and the cost of sewage treatment can be reduced, which was in line with the principles of clean productions and pollution treatments in the paper making industry.

Our advantages:

1. lower Fe content

2. Lower loss on ignition (LOI)

3. Fewer surface defects

4. Improved shrinkage control

5. Higher impact strength

6. Faster drying times

7. higher whiteness
