(1) No. 1 material high temperature resistant glass (350 degree high temperature glass)

Annealing temperature: 560-650 ° C

Temperature resistance after annealing: no longer than 280 ° C for a long time, up to 350 degrees for a short time

Regular thickness: 2mm-20mm

Production specifications: All specifications can be produced, and can also be processed into steps.

glass

(2) No. 2 material high temperature resistant glass (500 degree high temperature glass)

1, mechanical properties

Density ρ: 2.23 ± 0.02g / cm3

2, thermodynamic properties

Heat capacity: (20-100 ° C) 0.82KJ × (kg × K) -1

Thermal conductivity: 1.2W × (m × K) -1

3, optical performance

Refractive index: Nd: 1.43784

(3) No. 3 material high temperature resistant glass (1000 degree high temperature glass)

The thickness of such high temperature resistant glass is: 3mm, 4mm, 5mm, the conventional layout is 550*800, and the extra large layout can be 1960*1100.

The main highlight of this type of glass is that the glass can be cut into square models, round shapes, etc., without any processing method, and can also be opened according to the drawings.

(4) No. 4 material high temperature resistant glass (1200 degree high temperature glass)

This kind of glass is a glass with higher heat resistance temperature in all high temperature resistant glass products. It can work under high temperature environment of 1200 °C for a long time. It does not fade, deform or soften. It is an essential window glass for large high temperature open flame equipment.

The coefficient of thermal expansion is extremely small, and the bubbles, streaks, uniformity, and birefringence of this type of glass are comparable to those of ordinary optical glass. Working in a variety of harsh environments, with high stability, very safe and reliable.
