Water glass -- sodium silicate
What is sodium silicate?
There are two kinds of sodium silicate: sodium metasilicate, chemical formula Na2SiO3, formula weight 122.00. Sodium metasilicate is also known as "disodium trioxide," CAS No. 6834-92-0. The other is sodium orthosilicate (sodium orthosilicate), chemical formula Na4SiO4, relative molecular weight 184.04.3. Sodium metasilicate is a low molecular crystal produced by ordinary Paohua alkali and caustic soda hydrothermal reactions. The products include anhydrous, pentahydrate, and nine hydrates, of which nine hydrate only exists in the domestic market. It is an emergency product with low technical content that was urgently needed for sodium metasilicate in the 1980s and was hastily developed. Its melting point is only 42 ℃, so it is easy to become liquid or paste when stored and is being phased out gradually. However, due to some user habits and fields not paying much attention to crystal water, sodium metasilicate dihydrate still has a certain market.
Instant powder of sodium silicate
Instant powdered sodium silicate is also known as instant sodium silicate and hydrated sodium silicate. The product is white in appearance, powder in shape, and has good uniformity. It is very convenient to transport, store and use, especially for mechanized and automatic operation. It is widely used in metallurgy, electric power, petrochemical, and building materials industries. It is used as an adhesive, industrial cleaner, preservative in amorphous refractory materials, soap-making and acid-resistant cement, Quick drying agent, and reinforcing agent in the fine ceramics and precision casting industry. The instant powdered sodium silicate products also have all the properties and applications of liquid sodium silicate. The molecular formula of instant powdered sodium silicate is Na2O · mSiO2 · nH2O, and the formula is generally 280~350. Compared with the water-free powdered sodium silicate crushed by machinery, the former has many valuable properties, such as water dissolution rate, purity, etc. The instant powdered sodium silicate belongs to fine chemical products. It is made from the dry process (mirabilite process, soda ash process) of foam alkali through the processing processes of chemicals, filtration, mold adjustment, spray drying, etc.
Bonding agent of sodium silicate
In the 1950s, sodium silicate's carbon dioxide blowing process was widely used. This process had high sodium silicate content and poor collapsibility, and the old sand could not be recycled. It wasted silica sand resources, discharged many solid wastes, damaged the ecological environment, and produced rough-quality castings, making them face elimination. The new ester-hardened sodium silicate self-hardening sand was introduced in 1999. The sodium silicate content was 1.8~3.0%, with high strength and good collapsibility. The old sand was renewable and recycled, with a recycling rate of 80~90% and an adjustable service time. It can be used in mechanized molding and single-piece small-batch production. It can produce various castings of several kilograms to hundreds of tons. It has been popularized and applied in dozens of enterprises of railway vehicles, metallurgical machinery, heavy machinery, mining machinery, and general machinery plants.
Price of sodium silicate
Sodium silicate particle size and purity will affect the product's price, and the purchase volume can also affect the cost of sodium silicate. A large amount of large amount will be lower. The price of sodium silicate can be found on our company's official website.
