The basic usage method of water glass type acid-resistant cement: First, in principle, when mixing the clay or making acid-resistant concrete, hardener sodium fluosilicate should be added and fully mixed evenly with the acid-resistant cement. It's better to sieve it twice, then mix it evenly with the water glass solution whose specific gravity is between 1.38-1.45 and modulus is between 2.60-2.80. Second, during use, place the well-mixed product in a container first, then add the water glass solution, stirring must be even and agile; usually each time less than 100 kilograms should be stirred evenly, and all tools and containers used must not contain moisture or other impurities. When bonding acid-resistant bricks, staggered seams are required. Third, before construction, metal equipment should be derusted and cleaned, brick structures should be washed clean, and the surface of alkaline ordinary cement structures should be neutralized with acid first, then washed with water, and heated to dryness. Usually, the moisture content is required to be less than 4%. Fourth, acid-resistant cement should harden at a temperature above 15℃, and be maintained in the air for about 10-20 days (in winter, due to low temperature and longer time, it is best not to use), during the maintenance period, avoid contact with water and water components, do not expose directly to the sun to prevent cracking, and any cracks should be repaired in time, as long-term exposure can cause delamination. Fifth, after maintenance and drying, acidification treatment should be carried out. The basic method is to brush its surface with 40% sulfuric acid every four hours, and remove the crystalline material precipitated each time.
