Common tempered sight glass, also known as safety glass, tempered sight glass is actually a prestressed glass, in order to improve the strength of the glass, is the ordinary annealing glass first cut into the required size, and then heated to close to softening point of about 700 degrees, and then fast (Usually 5-6MM glass heated at 700 degrees high temperature of about 240 seconds, about 150 seconds cooling .8-10MM glass at 700 degrees high temperature heating about 500 seconds, about 300 seconds. In short, according to the glass The thickness of different, choose to heat the cooling time is also different). After the steel treatment of the glass surface to form a uniform compressive stress, while the internal tension is formed, so that the glass bending and impact strength can be improved, the strength is about four times more than ordinary annealing glass, but also enhance the glass itself, , Cold and heat, impact and so on

        Firing temperature: 730 ° C

        Annealing temperature: 650 ° C

        After annealing the highest temperature: 350 ℃

        After annealing safety temperature: ≤ 280 ℃

        Conventional thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 19mm

        Product pressure is better, glass transmittance> 95% widely used in military, electricity, petroleum, chemical, pharmaceutical, purification equipment, industrial wastewater treatment equipment, industrial furnace, high and low voltage transmission equipment, electrical control cabinet, , Actuators, transmitters, vacuum coating equipment, pipes, valves, tanks and other types of pressure vessels and instrumentation

Among them, the processing shapes are: round steel mirror glass, square steel mirror glass, trapezoidal steel mirror glass, fan-shaped mirror glass, profiled steel mirror, etc. to sample custom processing.
