Glass polishing material without using grinding paste and its using method

Abstract

A polishing material without abrasive and sludge for glass is prepared from the foamed elastomer prepared from polyester and polyurethane through solidifying, and cerium oxide-enriched RE oxide powder. Its advantages are high polishing quality, low cost and less environmental pollution.

Description

technical field [0001] The invention relates to optical glass polishing technology, in particular to a glass polishing material without abrasive slurry and a method for using the polishing material. Background technique [0002] Glass polishing technology is a post-processing technology for the production of optical glass. Its polishing quality and efficiency are related to the quality of the glass surface, the pressure and rotation speed of the polishing material on the glass surface, the concentration of the polishing powder on the contact surface, and the polishing material. Therefore, To obtain qualified and stable polishing quality and efficiency, the following three conditions must be met: 1) There is a high concentration of abrasive materials on the grinding surface of the glass; 2) There is a certain grinding disc pressure on the grinding surface of the glass ; 3) On the grinding surface of the glass, there is a high rotational speed of the grinding disc. Of course, ...

Problems solved by technology

However, the polishing process of the prior art is to supply abrasive powder to the grinding surface with the slurry circulation of different concentrations. Therefore, in order to obtain the high-concentration rare earth abrasive material on the grinding surface, the input amount of the rare earth abrasive powder has to be increased, or even adopted. The way of directly spraying dry powder on the grinding surface, due to the circulation of the slurry during the process, leads to a great waste of rare earth abrasives. At the same time, due to the continuous falling glass debris entering the slurry during the grinding process, the quality of the abrasive slurry continues to decline. Lead to discarding pulp, and unable to grind out qualified finished products

[0003] To sum up, the defects of the prior art mainly include: 1) low yield of one-time grinding; 2) high polishing cost; 3) serious waste of raw materials; 4) serious environmental pollution;
