With the rapid development of the world automobile industry, the production process of automobile rearview mirrors has also made great progress, and then higher requirements have been placed on the performance and quality of the mold bricks. The glass bending brick has the following characteristics: First, the change of the reheating line is low, because the glass bending brick is sintered at 1050 ° C, which ensures the long-term use of the glass bending brick at 800 ° C. The characteristics of the burning line change to zero and no deformation; Second, the structure is fine, the glass bending brick is formed by micron material mixing by high-speed agitator, and the coarsest material particles in the batch are less than 1000 mesh, sectional structure Very fine; Third, the thermal shock stability is good, the glass hot bending mold brick will not appear any cracks (including cracking phenomenon) during long-term use; Fourth, the processing is convenient, the glass hot bending mold brick is according to user requirements specifications Made, this avoids the problem of large cutting and waste; fifth, the price is low, the price of glass bending bricks is lower than that of similar products. Glass hot bending mold bricks can also be used in industries such as hot bending glass, hot melt glass and process glass.
