Description
I. product structure
Wear-resisting ceramics is a small square special ceramics (alumina) embedded within the special rubber, a square wear-resisting rubber lining, then the use of high strength organic adhesive will adhesive lining board in the device's inner shell, sheet metal forming strong and buffers to wear layer, is currently the best wear products.
Ii. Product use
It is widely used in the coal conveying system of coal fired power plant, the conveying system of the metallurgical and steel industry, the material bin of the batching system and the hopper, etc. The liner can be twisted and cut, suitable for the installation of all kinds of special equipment, and water and weak acid and alkali resistance. But for rubber aging at high temperature, limit under 100 ℃ temperature environment use.
