Application of Potassium Silicate

Potassium silicate can be used in the manufacture of high-grade welding electrodes, glass, ceramics and refractory materials, as well as cleaning agents, etc. Its application examples are as follows:

1. Preparation of a potassium silicate glass,

Specifically, it is implemented according to the following steps: Step 1: Put tetraethyl orthosilicate, water and ethanol in a container and mix them into a homogeneous solution, then add hydrochloric acid and KCl solution sequentially under stirring conditions to obtain a mixed solution; Step 2: Mix the mixed Put the liquid into an oven for constant temperature treatment for 28-30 hours; Step 3: After the mixed liquid forms a gel, lower the temperature of the oven and perform constant temperature treatment for 50-60 hours to obtain a semi-finished potassium silicate glass; Step 4: Semi-finished potassium silicate glass Take it out from the oven and place it in a crucible, place the crucible in an oven with a temperature of 200-300°C, then raise the temperature of the oven to 500-600°C, after 2-3 hours of constant temperature treatment, close the oven, and wait for the semi-finished potassium silicate glass After cooling to room temperature in the oven, the potassium silicate glass is obtained, which has high purity and uniformity, and the preparation method is simple, and the requirements for production equipment are relatively low.

2. prepare a kind of high modulus potassium silicate inorganic nano-resin,

The preparation method sequentially includes the mixing process of raw materials and the preparation process of high-modulus potassium silicate inorganic nano-resin. The mixing process of raw materials is to first add an aqueous solution of low-modulus potassium silicate to the mixer, stir to form a vortex, and then add water in sequence. , silica sol, stabilizer, coupling agent, and mix them uniformly to obtain a prefabricated mixture. The preparation process of the high modulus potassium silicate inorganic nano-resin is to first heat the prefabricated mixture to 40~80°C, and then at this temperature, after heating The prefabricated mixture reacts circularly in the reaction system formed by the mixer, circulating pump, and high-gravity rotating packed bed, and finally obtains a modulus of 5.3~6.2, a solid content of 26%~30%, a particle size of 5~20nm, and a yield of 98.5% %~99% high modulus potassium silicate inorganic nano resin. The method not only improves product quality and storage stability, but also shortens reaction time and reduces energy consumption.

3. Prepare a potassium silicate-based nanocomposite emulsion,

It includes the following steps: first use nanometer potassium silicate solution and nanometer silica sol solution, add dropwise silane coupling agent to prepare nanometer high modulus potassium silicate solution, and then add nanometer organic emulsion into nanometer high modulus potassium silicate solution Composite and adjust the pH value to prepare potassium silicate-based nanocomposite emulsion. The potassium silicate-based nanocomposite emulsion prepared by the method has good film-forming effect and strong adhesion.

4. Preparation of a potassium silicate reinforcement material,

The reinforcing material is composed of potassium silicate aqueous solution with a modulus of 3.8-4, a curing agent, a crosslinking agent and a diffusing agent; the production method is to dilute the low modulus industrial potassium silicate with water, and raise it in a reactor. Its modulus reaches 3.8-4, dilute the potassium silicate solution with water, then add an appropriate amount of curing agent and cross-linking agent, and stir evenly; this curing agent can be brushed or sprayed, and it is water-resistant, CO2 resistance, weather resistance, ultraviolet resistance and thermal stability are all better than the prior art, easy to use, low cost, and at the same time, the reinforcing agent is colorless and transparent.


Potassium Type Series Colloidal Silica/Silica Sol
1. The colloid particles are minute, and the particle size can be controlled according to customers' requirements.
2. Colloidal silica/Silica sol has relatively large specific surface area, and high heat-resisting performance (1500-1600"C)
3. With low viscosity, it can soak the places where water soaks; therefore, it presents excellent dispersion and permeability.
4. When the moisture contained in silica sol is evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.
Product application: coating, refractory industries, investment casting, polishing etc.
