A mirror is a device used to observe materials inside containers and equipment.It is a safety accessory and should be checked regularly.It is divided into round and rectangular mirrors according to shape.According to the use of peeping and lighting vision mirror.According to the structure, it is divided into lined and unlined, with neck, with cover, double layer safety, heat preservation, with scraper, with washing device and suitable for powder materials
The raw materials used for glass vision mirror are special glass made by upgrading and tempering on the basis of comprehensive high temperature glass, temperature glass and high pressure glass.
Glass mirrors are mainly round and square, and the size and thickness of the layout are not limited.To buy glass goggles, first of all, we should determine the size and thickness, heat resistance requirements, pressure requirements and other relevant technical indicators, so as to select appropriate products.
The adoption of advanced cold processing technology ensures the inner quality and dimensional accuracy of all kinds of mirrors.The application of directionless "quenched temperature field" solves the problem of "edges and corners" of small-size glass mirror and ensures the high strength of glass mirror.
The effective service life of any glass mirror product is limited by a certain time, which is usually referred to as the aging of glass.
Glass lens
There are two common characteristics of the aging of glass goggles:
(1) The transparency of the glass gradually turns into a slight fog from the original smooth and bright, which is also called permeability.Once the glass mirror appears slight fog, be sure to replace the glass in time.
②, the glass cracks.This crack at the beginning of the basic fine hair, not easy to detect, which will test the use of unit equipment maintenance personnel is careful.
