Water glass is a very common chemical used in construction. It is also known as caustic soda or water glass in the market. It is usually in solid, liquid and water quenched forms. It is widely used and can be used with talcum powder. Mixed use. What are the uses of water glass in the end? What are its characteristics? Let's take a look with Xiaobian!
Water Glass Use-1. Configure Acid Resistant Concrete, Mortar
The water glass has good heat resistance and acid resistance. The water glass can be made into a mortar or concrete coating with good acid resistance by mixing a certain proportion of acid-resistant coarse and fine aggregate, proper amount of calcium fluorosilicate and mortar. It is used in acid-resistant equipment, acid storage tanks, acid-resistant floors and various storage tanks.
Water Glass Use - 2. Configuration Rigid Waterproof Coating
In general, when we decorate the roof or the ground, we will apply a rigid waterproof layer to extend the life of the house. And this type of waterproof coating is made of water glass as a waterproof base material, and then added with several kinds of terpenoids to mix and dispose quick-setting waterproofing agent. It can be used with cement slurry or concrete, and has the function of rapid condensation, and can be used for house repair. Leakage rescue and so on.
Water Glass Use - 3. Architectural Coatings
Adding appropriate water glass material to the architectural paint can effectively improve the weather resistance, penetration resistance and fireproof effect of the building as a whole, prolong the service life of the house, and has a good use effect; however, it should be noted that this type of architectural paint cannot be used in plaster. Used on the product, otherwise it will easily lead to the reaction of water glass and calcium sulfate in the gypsum and destroy the product.
Water Glass Use - 4. Reinforced Foundation
In order to improve the load-bearing capacity of the ground, liquid water glass and calcium chloride solution can be alternately poured into the formation to allow them to chemically react in the formation, produce silicic acid gels, fill the excess pores in the formation, and reinforce the foundation. This can effectively prevent the infiltration of ground water and soil consolidation.
Do not know the three major characteristics of water glass
1. When water glass is hardened, it can precipitate silicon gel and has good adhesion. It not only can effectively block the pore gap during use, but also has a good effect of preventing water penetration.
2. Water glass has good heat resistance, and its use in high temperature environment will not affect its normal use efficiency, but will also increase its drying speed, increase its strength, not easily cause fire and other hazards to the human body. Accident.
3. The water glass is poor in alkali resistance, easily soluble in water or alkaline solution. Because it is an acidic salt substance, in contact with alkaline substances, it is easy to have a neutralization reaction, thereby destroying the composition of the substance itself and reducing its own use efficiency.
Xiao Bian concludes: The above is Xiao Bian's introduction to the use of water glass and its use characteristics, I hope to help those who have trouble in this area. If you still want to know or consult more related issues, welcome to pay attention to this site!
