Does the temperature resistant glass need to be annealed?

[Zhongbo.com] Temperature resistant glass refers to high temperature glass that can withstand a certain temperature. Like high temperature resistant glass, the purpose of annealing of temperature resistant glass is to eliminate the stress structure inside the glass and prevent the risk of self-explosion of the glass. From a large scale, the temperature resistant glass is annealed. From a small scope, the temperature-resistant glass is different depending on the material, and the order of annealing is different.

Taking 350 degree temperature resistant glass as an example, the annealing temperature is uniformly cooled from a high temperature kiln of 600 degrees to less than 100 degrees. This process is a process of gradually cooling, and the purpose is to uniformly cool the glass.

According to the relevant data, the annealing of 350 degree temperature resistant glass, the viscosity is 9-1012Pa.s, the annealing point is generally 550 °C-650 °C, the glass is kept at this temperature for 2-3 minutes, the stress is basically eliminated by more than 90%. The temperature at which the furnace is annealed is also called the strain point of the glass. When the glass leaves the heat treatment furnace, it must be rapidly cooled.

For 800 degree temperature resistant glass, there is no need for secondary annealing. Any shape and size can be cut directly on the original glass.

Bed Blankets

There are rich plush wool fabrics on both sides, and the surface has rich plush fabrics. Bed wool fabrics with thermal insulation properties can also be used as bedspreads, tapestries and other decorations. It is divided into three categories: pure wool Blanket, blended wool blanket and chemical fiber blanket. According to the weaving method, it is divided into organic weaving, tufting, warp knitting, needle punching, stitching, etc.
