Are ceramics wear-resistant?
Wear-resistant ceramics are special corundum ceramics made of AL2O3 as the main raw material, rare metal oxides as the fluxing agent, fired at a high temperature of 1700℃, and then combined with special rubber and high-strength organic/inorganic binder respectively.
BD series wear-resistant ceramic adhesive (1) and multi-component resin were selected for compounding. Epoxy resin, phenolic epoxy resin, silicone resin and DBT-7 toughening agent are mixed in a proper proportion to maximize the performance of various resins; (2) The curing agent is compounded by multiple compounding principle. After reacting with the main agent, the aging resistance and wear resistance of the cured product under the working conditions of temperature resistance and high temperature are improved. (3) The performance of construction technology has been greatly improved. For example, BD 18 1 Wear-resistant ceramic glue can be used for the facade and ceiling of construction equipment without supporting measures such as magnets, so as to meet the performance requirements of construction under different environmental conditions.
The temperature resistance, aging resistance and other indicators of this project have caught up with and surpassed some imported wear-resistant ceramic adhesives. For example, BD400 high temperature adhesive can withstand the high temperature of 450℃, and BD 1200 high temperature adhesive is suitable for bonding at 1200℃. Wear-resistant ceramic adhesive has obtained national invention patent.
How to distinguish ceramics
First: look at the appearance. From the appearance, a good ceramic surface is fine, smooth and uniform, with few trachoma and magazine particles, not only glazed, but also fine and uniform on the unglazed side.
Second: try to feel. After looking at the appearance, we want to know whether the ceramics are fine and smooth, so we still need to touch them by hand.
Third: try the weight. Good ceramics will be heavier in your hand.
Fourth: test density. Everything has density. The lower the density of some things, the better. Ceramics have higher density. Then pay attention to the resolution density? In addition to the detailed appearance above, a dripping test is also needed. If the water absorption is slow or even invisible, then the density of ceramics is very high and it is a high-quality ceramic.
Fifth: listen to the sound. Good ceramics, when struck by hands or hard objects, sound crisp and pleasant.
