Introduction to glass fiber cloth and magnesium chloride in glass magnesium cement material

First, the knowledge of glass fiber cloth:

　 　 The glass magnesium cement material itself is a brittle material, and the tensile strength is relatively low. In order to increase tensile strength, only fibers or fiber cloth can be added to strengthen. Glass fiber cloth is a mandatory material for the production of fireproof boards, air conditioning pipes, biogas digesters, handicrafts and other magnesium oxide products. The quality of the glass fiber cloth directly affects the quality of the glass magnesium fireproof board, and the glass fiber cloth can be divided into high alkali and medium alkali according to the alkali content. It is not recommended for high alkalis, because the tensile strength and durability of high alkalis are not worse than those of medium alkalis. In addition, high-alkali glass fiber cloth is prone to the phenomenon of anti-halogen and anti-alkali. Then there is the density problem, density is the number, there are 1 2 3 4 four, according to the needs of customers to do.

　 Second, the knowledge of magnesium chloride

　 　(1) Magnesium chloride hexahydrate

　 　 It is formed after the salt field purifies potassium chloride sodium chloride with the remaining brine or natural halogen powder from the salt. Industrial production of magnesium chloride (halogen powder, halogen flakes). Magnesium chloride content is high, less impurities, basically can meet the quality requirements of the use of magnesium chloride in glass magnesium plate.

　(2) Anhydrous magnesium chloride

　 　 It is a by-product of sponge titanium plant, characterized by high chloride ion content, less impurities, and the production of magnesium cement using anhydrous magnesium chloride is not easy to reverse halogen and alkali phenomenon. However, magnesium chloride anhydrous also has disadvantages, which should be selected according to different magnesium products industries.
