Used as adhesives for corrugated paper, metal preservatives, water softeners, detergent auxiliaries, refractory materials and ceramic raw materials, bleaching, dyeing and pulping of textiles, mine dressing, waterproofing, plugging, wood fire prevention, food anticorrosion and adhesives Wait……
Its specific description is as follows:
1. Brush the surface of the material to improve weathering resistance
Water glass solution can penetrate into the gaps and pores after brushing or impregnating the material, and the solidified silicone gel can block the pore channels, increase the density and strength of the material, and thus improve the weather resistance of the material. However, water glass must not be used to paint or impregnate gypsum products. Because water glass reacts with gypsum to produce sodium sulfate (Na2SO4), it crystallizes and expands in the pores of the product, causing cracking and destruction of the gypsum product.
2. Reinforce the soil
Water glass and calcium chloride solution are alternately injected into the soil, and the two solutions react quickly to form silica gel and calcium silicate gel, which play the role of cementing and filling pores, and improve the strength and bearing capacity of soil. Commonly used for silt, sand and fill foundation reinforcement, called double-liquid grouting.
3. Formulate quick-setting waterproofing agent
Water glass can be formulated with a variety of alum as a quick-setting waterproofing agent for local repairs such as plugging and caulking. This polyalumina waterproofing agent has a fast setting speed, usually several minutes, and the alum waterproofing agent does not exceed 1min, so it must be used immediately when used on the construction site.
Four kinds of alums are commonly used as alum waterproofing agents: alum (copper sulfate), red alum (potassium dichromate, K2Cr2O7), alum (also called alum, potassium potassium sulfate), and alum.
4. Preparation of acid-resistant gel, acid-resistant mortar and acid-resistant concrete
酸 Acid-resistant gelling is formulated with water glass and acid-resistant powder (commonly used quartz powder). Like acid-resistant mortar and concrete, it is mainly used in projects that require acid resistance. Such as sulfuric acid pool.


5. Preparation of heat-resistant gel, heat-resistant mortar and heat-resistant concrete
Water glass cement is mainly used for masonry and repair of refractory materials. Water glass heat-resistant mortar and concrete are mainly used for blast furnace foundation and other structural parts with heat resistance requirements.
6. Application of anticorrosive engineering
Modified water glass acid mud is an important material for acid corrosion resistance. Its main characteristics are acid resistance, temperature resistance, compactness and impermeability, low price and easy use. It can be mixed into acid-resistant cement, acid-resistant mortar and acid-resistant concrete. It is suitable for anti-corrosion projects of various structures in chemical, metallurgy, power, coal, textile and other sectors. The ideal material for building.
