Performance of tempered sight glass
Tempered glass is also called safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, the ordinary annealed glass is cut to the required size, and then heated to a softening point close to about 700 degrees, and then quickly and uniformly cooled to obtain (usually 5-6MM glass) 700 degrees high temperature heating for about 240 seconds, about 150 seconds. 8-10MM glass is heated at 700 degrees for about 500 seconds and cooled for about 300 seconds. In short, depending on the thickness of the glass, the heating and cooling time is different).
Firing temperature: 730℃
Annealing temperature: 650℃
Maximum temperature after annealing: 350℃
Safety temperature after annealing: ≤280℃
Conventional thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 19mm
The product has better pressure resistance, and the glass light transmittance is >95%. It is widely used in military, electric power, petroleum, chemical, pharmaceutical, purification equipment, industrial wastewater treatment equipment, industrial furnaces, high and low voltage power transmission equipment, electrical control cabinets, and actuators. , Transmitters, vacuum coating equipment, pipelines, valves, tanks and other pressure vessels and instruments.
Among them, the processing shapes are: round, square, trapezoidal, fan-shaped, special-shaped, etc. Customized processing according to drawings.
