Do you know Low Sodium Type Colloidal Silica/Silica Sol?
Colloidal silica, also known as silica sol, is a type of dispersion of small silica particles in a liquid medium. It is a highly concentrated form of silica that is stable and easy to handle. Colloidal silica is often used as a filler, abrasive, or reinforcing agent in various industrial and consumer products, such as adhesives, coatings, elastomers, and composite materials.
Low sodium colloidal silica is a type of colloidal silica that has had its sodium content reduced or removed. Sodium is a metallic element that is naturally present in silica and can be harmful in high concentrations. Low-sodium colloidal silica is often used in applications where the presence of sodium may cause problems, such as in the production of pharmaceuticals or food products.
There are several methods that can be used to produce low-sodium colloidal silica, including ion exchange, distillation, and precipitation. The specific method used may depend on the desired purity and concentration of the final product, as well as the cost and availability of the raw materials.
Colloidal silica/Silica sol is a kind of colloid which is formed by nm-grade particles SiO2, dispersed in water. It is odorless, tasteless, and nontoxic and its chemical molecular formula is mSiO2·nH2O.
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: electronics chemicals, paper chemicals, ceramics, sapphire polishing, gallium arsenide, silicon wafer polishing, cement curing agent, refractory materials, etc.
