Glass magnesium board production process who knows ah
Factory moisture problem: glass magnesium plate used in different areas, the water content requirements are not the same. The use of high water content of the plate used in dry areas, plate shrinkage serious; and low water content of the plate used in wet areas, plate wetting serious. Thus the manufacturer should control the different moisture content according to the different use areas. Now can do this few manufacturers rarely.
Chloride ion content problem: glass magnesium plate due to the presence of a large number of chloride ions, prone to return to halogen, but also corrosive to metals, many users, especially exports require control of chloride ion content. Taiwan standard CNS14164 "magnesium oxide board" also has a special indicator. The results show that the higher the content of chloride ions in the same type of plate, the more serious the return of halogen, the stronger the corrosion. But different types (mainly filler, light burning and color) plate chloride ion content difference can not fully reflect its performance. For example, the filler content of the filler is small, the chloride ion content is high, but it does not return to the halogen and absorb moisture.
Glass magnesium board main raw materials: magnesium oxide (mainly light burned magnesium oxide powder), 6 water magnesium chloride (commonly known as halogen powder), wood chips, perlite, modifier. Recipe is very complex, the formula is only play a guiding role, mainly to continue to test, verify, improve, until you find their own production methods and formula. Probably the process is: choice of materials, ingredients, foam, molding, maintenance, trimming, (deep processing, etc.). The following are some of the production should pay attention to the anti.
