Measures of Wiskind Control for Anti - Halogen Bulge Cracking of Glass Magnesium Plate

Cause of anti-halogen bulge in glassy magnesium plate

Cleanroom panel core material glass magnesium plate and glass magnesium grillage in the application is easy to appear the phenomenon of bulge and crack, and a big reason for the bulge is caused by glass magnesium plate return halide, in fact glass magnesium plate return halide is a little similar to the phenomenon of cement panalkali.The return halide directly leads to the partial separation of glassy magnesium from the steel plate, resulting in bulging and even disconnection of the panel.

Wiskind control measures

Since its establishment, Wiskind laboratory has been committed to the detection of raw materials and finished products and the experiment and research and development of new products. In view of the phenomenon of anti-halogen bulging, we have special testing equipment, including the moisture content of glass and magnesium and return halogen, mainly to prevent the quality problems of finished products such as plate bulging.The equipment can be used to detect temperature of -10~105℃ and humidity of 10~98%, including experiments under the condition of rapid cooling and heating.

By controlling the quality of products from the source, mastercard insists on providing products with better value for money.

① For the anti-halogen bulges, there is a certain relationship between the spacing of the fiberglass mesh, the stability of the material and the size of the board, and the resistance to cracking.But at present on the market, non-gb glass magnesium plate is double-sided clay pot cloth, density is small 12g/㎡, clay pot cloth is not used for a long time, or the sun exposure is easy to powder, mesh spacing, cheap.

② The glass fiber mesh cloth used by Wiskind is the national standard mesh cloth, front single side platinum cloth + back single side earth pan cloth, mesh 4mm*4mm, density 50g/㎡, platinum cloth aging resistance, high strength, expensive price.

③ The volume of glass magnesium board also affects the important points of anti-halogen drumming. Within the national standard requirement of 8%, the continuous production line of Wiskind has high requirements for the humidity of glass magnesium board. In addition, Taihua is required to increase the temperature of glass magnesium board by adding two greenhouses , Reduce the molecular weight, while the glass surface of the city's glass magnesium board is not protected, the length is about 12% -15%.

④ The national standard stipulates that the chloride ion content should not be greater than 10%, and the chloride ion content of the glass magnesium board used by Wiskind is 3.5%, which is much higher than the national standard.
