Chemical name: sodium metabisulfite.

Names synonymous with meta-sodium: sodium meta-silicate, liquid glass, liquid gas, E550, sodium silicate.

Product Grade: 1. Meta Meta sodium silicate sodium silicate industries 2. Laboratory.

Types: 1. Dried 2. Meta Meta sodium silicate Sdymabdar.

Chemical formula: Na2SiO3.

Purity: 99% sodium metabisulfite.

Appearance: meta sodium silicate and sodium silicate liquid is in the form of powder.

History: Sodium silicate Chemical Technology Guide Written by definition soluble alkali silicates von Wagner is a 1892 translation of the first was discovered in 1640 by Van Hlmvnt.

Sodium silicate glass also called the water that is available in solid form. Of liquid solution in soap making, industrial cleaning, adhesives, cement, paint, die-casting, durable and corrosion control of peroxide in the mixture of water and a precursor silica zeolite is used.

Indications and Usage: meta sodium silicate is used in various industries:

1.snay Ceramic tiles: the slurry is used as a lubricant raw material (adhesive materials, finely milled). This product can be prevented from cracking products when cooking. This material is molded bodies that lack natural Sayrz as well as raw can be used powders that need to connect to reinforce their strength.the lowest possible temperature and the body burned out.

2. Metal melting and casting industries: Protective coatings resistant to mold (template) and used for cleaning. Another use of sodium silicate iron castings and steel and iron industry of the 1950s. Initial hardening sodium silicate sand mixture in the presence of carbon dioxide causes a chemical reaction between carbon dioxide and the sodium silicate.

the stand is placed. There are other types of metal muscles that are used in permanent mold and foundations muscle does not apply to them.

4. carton industry, paper and paperboard laminate: for increasing adhesion to the pulp, carton, cardboard tubes, glass wool barrels, paste as a binder in cardboard boxes and packaging lines (synthetic means) is used. In paper mills for bleaching and ink removal of silicate is used. Silicates are also stable hydrogen peroxide which may be added to the formulation deinking. Alkali silicates participate in deinking operations at lower ph only formulated using sodium hydroxide. Deinking ph lower turbidity in the solution is low that this issue is important in the pulp making.

5. detergent industries: for separation of suspended particles and keep them fat, prevent corrosion and generally it is used as a buffer solution. For centuries, both silicate and silicate liquid soap can be used as single manufacturer. Liquid silicate form in soaps and cosmetics are added to prevent rancidity. In a variety of commercial laundry and self-service, the meta-silicates known as a manufacturer of soap. Synthetic detergent, phosphate and other materials are used and cause corrosion of aluminum, zinc and certain alloys are used in the structure of household dishwashers. The use of sodium silicate in detergent compositions cause corrosion control and alkaline attack and emulsification of fats and oils of organic and reduce the calcium and magnesium hardness.

Production of sodium metabisulfite can be produced in two ways: dry and juicy as dry as the process of design calculations have been based.

Dry sodium silicate production process:

in the sand and alkali processed in a timely manner and accurately control done enough to melt almost blue light green color is obtained. The color because of impurities that is less than one percent and are usually caused by iron compounds.used high-pressure steam.

Quality control steps in the process are as follows:

1.andaz·h quartz particles.

2.dansyth sodium carbonate.

3.mqdar iron in silicate.

4.ghlzt consumer interest.

Sodium silicate production process more ways: directly benefit from the combination of silica stones at the required temperature in the reactor pressure sodium silicate is produced. Higher than amorphous silicates are possible using.

Packing: meta sodium silicate powder in bags of 25 kg and 20-liter and 220-liter liquid sodium silicate in gallons are available.
