Abstract

The invention discloses a method for manufacturing a quartz plane mirror for an anti-explosion lamp, which comprises the following steps of: 1) cutting a high-purity quartz lump by using an optical glass cutting machine; 2) milling and grinding the cut quartz blank by using a horizontal milling and grinding machine to obtain a formed quartz plane mirror; 3) performing fine grinding on the quartz plane mirror formed by milling by using a lens high-speed air pressure fine grinding machine; 4) performing ultrasonic cleaning on the quartz plane mirror subjected to fine grinding; 5) polishing the quartz plane mirror subjected to fine grinding by using a lens high-speed air pressure polishing machine; and 6) detecting the parallelism deviation of the quartz plane mirror by using a parallelism detector, and thus obtaining a finished quartz plane mirror product after the deviation is qualified. The quartz plane mirror manufactured by the method is high-temperature-resistant, good in light rays, free from cross scattering, high in transparency, uniform in texture and long in service time.

Description

technical field [0001] The invention relates to a preparation method of a quartz plane mirror for an explosion-proof lamp, in particular to a preparation method using high-purity quartz as a raw material. Background technique [0002] At present, in harsh environments such as coal mining, tunnels, oceans, exploration, flood fighting and emergency rescue, optical lenses, glass lenses and related explosion-proof glass products are required for high-brightness lighting. For electric light source lamps, explosion-proof transparent material is used as the shell, which can not affect the light and has explosion-proof function. It is an essential light source product material for safe production. At present, most explosion-proof miner's lamp masks use optical glass lenses, and their light transmission and transmission ranges are different. However, the processing technology of this kind of optical glass is complicated, and the high temperature resistance is less than 850°C. It is ...
