Description
Technical Field
The invention relates to a preparation method of glass for optical detection, which is particularly suitable for preparing chemical ingredients of lead-free special glass for energy-saving lamps, and belongs to the technical field of manufacturing of energy-saving lamps.
Background
The lead content in the chemical ingredients of the glass used in the energy-saving lamp in the current market is higher. It is well known that lead evaporates when it is subjected to certain temperatures. Various glass products are obtained under high temperature conditions, which is determined by the processing technology of the glass products. Therefore, the environment pollution of the glass product manufacturing workshop is serious, and the lead poisoning phenomenon of operators happens occasionally. Even if we have obtained the desired glass tube, lead evaporation is also present when such a high-lead or medium-lead containing glass tube is used in energy saving lamps. Therefore, the domestic and foreign markets, especially the European and American markets, all require that the core column, the horn bulb and the rice bulb of the energy-saving lamp can not use high-lead or medium-lead glass. Based on the current situation, the development of a chemical ingredient component of the lead-free special glass is very important nowadays when the awareness of energy conservation and environmental protection is increasingly strengthened.
In view of the above-mentioned drawbacks, the present designer is actively making research and innovation to create a method for preparing glass for optical inspection, so that the glass has industrial application value.
