Frequently Asked Questions

As a leading Water Glass Curing Agent supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

What are the main components of water glass curing agent?

The main component of water glass curing agent is sodium silicate. Sodium silicate, also known as capsuline, its aqueous solution is called water glass, which is an inorganic adhesive. In many industrial fields, water glass is widely used. During the curing process, the main component involved is sodium silicate. The chemical composition of sodium silicate determines that it has special physical and chemical properties. When water glass is about to cure, sodium silicate will undergo a series of chemical reactions. Under certain conditions, the silicate ions in sodium silicate will gradually polymerize, and then form a solid substance with a network structure. This is the basic process of curing water glass. The common water glass curing agent, in addition to sodium silicate itself, also has other auxiliary ingredients to promote the curing process. For example, some acid substances can react with sodium silicate to accelerate the polymerization of silicate ions. During this process, acid substances interact with sodium silicate to change its chemical balance, resulting in an increase in curing speed. Another type of curing agent is metal salts. Metal ions can combine with silicate ions in sodium silicate to form a more stable complex structure, thereby enhancing the curing effect. These metal salt curing agents can promote water glass to achieve higher strength and hardness in a short time. In short, the main component of the water glass curing agent, sodium silicate and related auxiliary components, achieve the purpose of curing through complex chemical reactions during the curing process of water glass, so that it plays an important role in many fields such as construction, casting, and anti-corrosion, and builds a stable structure and protective system.

What is the scope of application of water glass curing agent?

Water glass curing agent has a wide range of applications. In civil engineering construction, it can be used to strengthen soil. Where the foundation is viewed, if soft soil is encountered, water glass and suitable curing agent are mixed and injected into the soil, the soil particles will have the effect of cementation, and the foundation will be strong and strong. It can bear the weight of the house, making the house stable and not collapsed. As for the repair of building materials, it is also commonly used. If there are cracks in the masonry wall, inject the liquid of water glass curing agent. When it solidifies, it can bridge the gap, restore the integrity of the wall, and enhance its resistance to wind and rain erosion. In the chemical industry, its effect is also obvious. In some anti-corrosion projects, a coating made of water glass curing agent can be applied to resist the corrosion of chemical substances. Such as the floor and walls of a chemical workshop, after this treatment, it can be durable and not damaged by strong acids and alkalis. And in the casting process, it is also indispensable. When sand casting, water glass is used as a binder and a curing agent is added to make the sand mold rapidly curing and form, ensuring the accuracy and quality of the casting, so that the cast product complies with regulations and is flawless. And in the production of refractory materials, water glass curing agent is also wonderful. It can enhance the strength and adhesion of refractory materials, so that they are still stable in high temperature environments and will not collapse. It can provide reliable protection for kilns, furnaces and other facilities. In short, water glass curing agents have important applications in many industries such as civil engineering, chemical industry, foundry, etc., but they have many functions and great benefits.

What is the main function of water glass curing agent?

The main function of water glass curing agent is to induce the sodium silicate (i.e. water glass) system to solidify quickly and transform into a hard inorganic solid structure. Water glass solidifies slowly in its natural state, especially in an environment with high air humidity or low temperature, and its curing process may take several hours or even longer. After adding the curing agent, by changing the pH value and ionic strength of the solution or promoting the polymerization of silicate, the colloid is quickly precipitated and dehydrated, thereby achieving coagulation within a few minutes to tens of minutes. Curing agents can significantly improve the compressive strength, water resistance, corrosion resistance and volume stability of the cementitious system, and are widely used in casting binders, refractory forming agents, concrete additives, foundation grouting, tunnel water sealing, anti-seepage projects, etc. Different scenarios have different requirements for curing time, forming strength and later stability, so choosing the right type of curing agent is one of the key process parameters.

How is the compatibility of water glass curing agent with other materials?

The compatibility of water glass curing agent with other materials mainly depends on its chemical composition and the characteristics of the materials it is combined with: it has good compatibility with inorganic materials, can form anti-corrosion coatings with metals such as steel and aluminum, has good adhesion with mineral materials such as sand and ceramic powder, and can also be used as an additive to improve the strength and water resistance of cement concrete; it has limited compatibility with organic materials. Due to the polarity of water glass, it is usually not easy to mix with non-polar polymer materials such as plastics and rubber, but surface modification treatment (such as introducing organic functional groups) can improve the binding force with some resins to a certain extent; it has the best compatibility with water glass itself and similar silicate materials, which can enhance the bonding and curing effect, but chemical reactions may occur when in contact with acidic materials or strong electrolytes, affecting the curing performance. When using, attention should be paid to the acidity and alkalinity of the system and the chemical matching between materials.

How to evaluate the curing efficiency of water glass curing agent?

Curing efficiency is an important basis for measuring the performance of water glass curing agent, and is usually comprehensively evaluated from multiple aspects. The primary indicator is the setting time, which is divided into two stages: initial setting and final setting. The target needs to be set in combination with the specific use (such as the initial setting in the casting sand mold needs to be controlled within 10 minutes). The second is the mechanical strength after curing, which is often quantified by compressive strength and flexural strength tests, especially in the early (24h) and late (7d, 28d) stages. The third is water resistance, which tests its structural stability and strength retention rate after long-term immersion in water, which is a key performance in construction, waterproofing or soil consolidation applications. In addition, attention should be paid to volume changes during the curing process (such as shrinkage and cracking), heat resistance (no decomposition at high temperature) and compatibility with other components. Standard test methods can refer to GB/T 17671, ASTM C109 and other specifications, and experimental data can provide a scientific basis for product screening and process optimization.
