Sodium silicate glue and its applications in industry

 What is sodium silicate?

Silicates are negatively charged chemical compounds of silicon. Sodium silicate is a white powder. When this substance is dissolved in water, it creates an alkaline solution. Sodium silicate is also known as "water glass" or "liquid glass" which is available in solid form.

What do you know about the use of sodium silicate in the carton industry? The most important application of sodium silicate in the carton industry is as a glue in carton making. In cement making, mold casting, soap making, industrial cleaners, corrosion control in water pipes can also be mentioned. This material is used in liquid form in detergents, wall coverings and insulation, building roof tiles. Insulin aids, catalyst bases, chemicals are also used.

This substance is stable in neutral and alkaline solutions.In a process, hydrogen ions and silicate ions react together and form silicate acid. When it heats up, it forms a glass material called silica gel. It is produced in two ways: wet and dry. Production methods are described below.

What is sodium silicate?

Alkaline sodium silicate:

If dry soda is added to the furnace during melting, alkaline sodium silicate is formed. High pressure steam is used to dissolve sodium. Silicates stabilize hydrogen peroxide and play a buffer role. Silicates are deinked in low pH by sodium hydroxide, which makes the solution turbid, and this point is very important in the preparation of paper pulp.

Sodium silicate glue

Liquid sodium silicate is a water-soluble glass solution that is made from different proportions of sand (SiO2) and soda ash (Na2CO3). Most siliceous silicates (ratio 2.8 to 3.2) It has been used as a reliable and low-cost adhesive for a long time. And their viscosity varies from slightly viscous liquids to thick materials that resist flow.

Liquid silicates are cheap and readily available. Silicates are non-flammable adhesives. They are odorless and do not give any taste to the contents of the packages in which they are used as adhesives and are recognized as safe by the Food and Drug Administration. Read this article to learn more about the characteristics and application of this sample of adhesives.

Liquid sodium silicate glue is a miraculous glue that is often used in many industries. Among its distinctive features, we can mention resistance to wear, combustion and water.

Properties of liquid sodium silicate glue

Liquid sodium silicate glue has a high thickness and a clear color that sometimes has a yellowish or green tint.Other features of these adhesives include the following:

Silicate glue has a high penetrating power on surfaces.

Firm, permanent and strong adhesion

It has high resistance to temperature. The insulating base made of silicate glue can withstand a temperature of 1300 degrees.

Silicates are an excellent and inexpensive alternative to latex and other adhesives.

They are environmentally friendly.

Resistance to water and adverse weather conditions.

Prevents metal surfaces from rusting.

It penetrates into the smallest gaps and increases the strength of structures.

It is easy to use.

The storage time of liquid sodium silicate glue is about 2 years.

The quality of the glue is not lost under the influence of temperature reduction
