Product Details

highly-alumina-ceramic-lining-tiles


Highly alumina ceramic lining tiles are adhered to the inner wall of the equipment by heat - resistant adhesive. Under the 350 ℃ can run for a long time not aging, the cementation type products used for the 750 ℃ of heat-resistant inorganic binder. The resistance temperature and adhesion performance index of adhesives are well ahead in China.

Highly alumina ceramic lining tiles adhesive is a kind of high performance adhesive which is specially used to paste the wear-resisting ceramic lining onto the substrate surface of the equipment.
