c0f85347 Applicable Equipment

This product is specially for lithium ion battery ceramic diaphragm special requirements of the development of high purity alumina.As a coating material, this product can effectively improve the high temperature resistance and safety of lithium batteries.And can be widely used in high pressure sodium lamp, phosphors, synthetic aluminum nitride raw materials, high-grade electronic ceramics, artificial crystal and other fields.

c0f85347 Features

1, the crystal morphology is good, the specific surface area is small, can effectively reduce the ceramic diaphragm water, and reduce the coating roller wear, extend its service life.

2, high purity, narrow particle size distribution, can reduce the diaphragm plugging rate, good permeability, uniform coating thickness, smooth film surface, heat shrinkage.

3. Stable process performance, good dispersion, and good stability of water-based paste satisfying different adhesives.
