From the perspective of chemical properties, the modulus of potassium silicate has a decisive influence on its various properties. The larger the modulus, the worse the solubility of potassium silicate, and the higher the liquid viscosity and bonding strength. For Modulo(M):3.3±0.1 Powdered Potassium Silicate, its dissolution rate is relatively slow. At 30°C, it takes up to 8-12 hours to achieve complete dissolution. This feature makes it have certain application limitations in some occasions where the reaction speed is extremely high. For example, in a chemical synthesis production line with a high degree of automation, the raw material mixing reaction needs to be completed within a few minutes. This slow dissolution rate may disrupt the precisely designed production rhythm and affect the efficiency and progress of the entire production process.
However, this higher modulus also brings it significant advantages. The higher modulus means that it has excellent bonding properties and good water resistance. Taking the field of building reinforcement as an example, in the reinforcement project of bridge piers, potassium silicate with a modulus of 3.3±0.1 is used as a binder, which can make the reinforcement material closely combined with the original structure, and can still maintain high-strength bonding under long-term traffic loads and extreme climate influences. Data from a third-party testing agency shows that the shear strength of the reinforced structure using potassium silicate with this modulus is 35% higher than that of ordinary binders, effectively resisting the influence of external environmental factors such as wind and rain erosion, temperature changes, etc., and extending the service life of the building.

Powdered potassium silicate also has the characteristics of being able to be quickly dissolved and used on site. Although potassium silicate with a modulus of 3.3±0.1 itself dissolves slowly, powdered potassium silicate treated with special processes can be quickly dissolved on site in actual applications. In municipal emergency repair projects, construction workers use warm water stirring and mechanical stirring devices to shorten the dissolution time of powdered potassium silicate to less than 30 minutes. This instant dissolution and use feature is particularly suitable for emergency projects and projects in remote areas. It does not require a large amount of preparation in advance, effectively improving construction efficiency and reducing material waste.
