The solution is as follows:
1. To control the quality of raw materials, the true content of active magnesium oxide and effective magnesium chloride in raw materials must be detected before use. If there is no detection condition, the true content of raw materials should be known in detail through raw material suppliers;
2. The scientific dynamic ratio can be adjusted according to the actual production environment to avoid the same ratio unchanged all the year round;
3. Necessary and effective amendments;
4. Correct and standardized technological process, clear batching process, and strictly follow the operation sequence. Pay attention to humidity and temperature during the curing process of the product, so that the later curing reaction can proceed smoothly and the physical and chemical properties of the product meet the requirements.
Pan-alkali: Generally speaking, we refer to the phenomenon of white frost on the early surface of magnesite products, which mainly refers to the precipitation of magnesium oxide on the surface of products with the evaporation of water, forming white powder, and this white frost has little effect on the properties of products.
Of course, after some products are used for two to three years, due to the constant frosting and halogen return during this period, an obvious salt frost layer is formed on the surface of the products, which will seriously affect the service life of the products.
