Do you need to know ahead of time when buying water glass?
福彩3D走势图Water glass is often used in our lives. In fact, it is also sodium silicate. So, do you need to know the water glass when you buy it? Let's take a look at the water glass manufacturer.
1. Before purchasing water glass, you must first have a certain understanding of it, such as the performance, use and precautions of water glass.
2, the purchase of water glass, but also to determine the good manufacturers, after all, there are many manufacturers of water glass, it is recommended that many of the comparison.
3, also need to determine the use of water glass, because its use is more extensive, applied in different aspects, the requirements for various aspects are not the same.
Water glass performance
福彩3D走势图1, performance parameters. The chemical formula of water glass is R2O·nSiO2, R2O is an alkali metal oxide, and n is the ratio of the number of moles of silica to alkali metal oxide, that is, the modulus of water glass. The density of water glass commonly used in civil engineering is usually 1.36-1.50 g/cm3. The modulus of water glass is usually between 1.5 and 3.5. The higher the modulus of water glass, the harder the solid water glass is. It is more soluble in water. The higher the silica content, the stronger the viscosity of water glass, the easier it is to decompose and harden, and the stronger the bonding force.
2, performance advantages. The water glass has a high bonding ability, and a silicic acid gel is precipitated during hardening, which can block capillary pores and prevent water from penetrating. Water glass has good heat resistance and flame retardancy. At high temperatures, the silicic acid gel dries more strongly, and the strength does not decrease or even increases. Water glass can withstand almost all inorganic acids and organic acids other than 300 ° C phosphoric acid, higher fatty acids or oleic acid.
福彩3D走势图Use of water glass:
福彩3D走势图1. Configure acid-resistant concrete, mortar
福彩3D走势图Water glass has good heat resistance and acid resistance. The water glass is mixed with a certain proportion of acid-resistant coarse and fine aggregate, appropriate amount of calcium fluorosilicate and mortar, and can be made into mortar or concrete paint with good acid resistance. It is used in acid-resistant equipment, acid storage tanks, acid-resistant floors and various acid storage tanks.
2. Configure rigid waterproof coating
Generally speaking, when we are decorating the roof wall or the ground, we will apply a layer of rigid waterproof layer to extend the service life of the house. This kind of waterproof coating is made of water glass as waterproof base material, and then added with several kinds of hydrazine materials. It can be used with cement slurry or concrete. It has the function of rapid condensation and can be used for house repair. Water leaks and rescue.
3. Reinforce the 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, so that they can chemically react in the formation, produce silicic acid gel, fill excess pores in the formation, and strengthen the foundation. This can effectively prevent the penetration of ground water and the consolidation of soil.
福彩3D走势图4. Architectural coatings
Adding appropriate water glass materials to architectural coatings can effectively improve the weathering resistance, permeability resistance and fireproofing effect of the building as a whole, prolong the service life of the house, and the effect is good; however, it should be noted that such architectural coatings cannot be used in plaster. It is used on the product, otherwise it will easily cause the water glass to react with the calcium sulfate in the gypsum to damage the product.
福彩3D走势图In summary, it is necessary to know the relevant issues in advance when purchasing water glass. I hope that the above introduction can help everyone.
