About silicate glue product

About the product:

Sodium silicate glue is one of those widely used chemical compounds that can be used in various fields. This product has amazing applications all over the world and in various industries, and for this reason, it is known as a widely used chemical solution.

This valuable and practical compound was discovered by Van Helmont in 1640 and entered many industries with the description that sodium silicate glue is an alkaline and soluble substance.

This alkaline substance is soluble in water in two types, liquid and solid. Its solid type is in the form of transparent pieces or white powder. These compounds do not dissolve in acids and alcohols, and when dissolved in water, an alkaline solution is produced. It is commonly used in many industries and health products. The presence of this mineral compound in certain products makes it hard and resistant. The higher the amount of this compound in the product, the higher its hardness and resistance.

Sodium silicate is also known as glass water. This alkaline substance exists as a nearly colorless, glass-like powder or as a syrup-like liquid when mixed with water and pressurized.

It is a combination that contains sodium oxide and silica. The viscosity of this compound varies according to the proportions of silica and sodium oxide used. Sodium silicate has various industrial, agricultural and manufacturing applications.

36. Production of sodium silicate glue is done in two ways.

    dry method
    more method

    In the dry method, sodium silicate glue is produced in large furnaces, such as glass melting furnaces. This process starts from mixing sand and sodium carbonate at very high temperature and melting these two materials. Normally, the furnace temperature increases to 1450 degrees Celsius.

    It can be said that insoluble sodium silicate is formed at this temperature and the composition of the mixture of sand (silica) and sodium carbonate is very important to produce a quality product.

    In the dry method, the sodium silicate produced will have a blue or light green color due to the very low percentage of some metal impurities.

    In another method, a reactor is used to produce this chemical compound. In this process, silica rock and sodium hydroxide (NaOH) enter the reactor under specific laboratory conditions. In the next step, powdered silica is added to the reactor through large conveyors, and in combination with soda and water, the sodium silicate production process begins.

    In this method, after the process is finished, the products are transferred to the sedimentation tank and then dried until sodium silicate crystals are obtained.

    Technical and analytical specifications of sodium silicate

    To use or buy any substance, it is necessary to analyze that substance. In many chemical substances, according to the nature of the substance, only the purity or density of the substance is relevant, which means that by knowing the density of an acid such as sulfuric acid, you can obtain all its other properties using tables, but in sodium silicate, according to The relative ratios of SiO2 to Na2O cannot be determined by having one technical characteristic, in other words, by having at least two technical characteristics of sodium silicate, its precise characteristics can be determined.

    In a sodium silicate technical sheet, the following should be mentioned:

    Ratio, Solid Content, SiO2 percentage, Na2O percentage, specific gravity, pH and viscosity

    Ratio: The weight ratio of SiO2 to Na2O in sodium silicate is called ratio. Considering that the molecular mass of SiO2 is close to the molecular mass of Na2O, the molar ratio is almost equal to the weight ratio in sodium silicate.

    Weight ratio * 1.03 = molar ratio (for sodium silicate solutions)

    Sodium silicate solutions with ratios of 2 to 3.3 with different dissolved solids are produced for different uses.

    The solid content of the solution: The solid content of the solution, which is used as a price calculation criterion in many industries, including the detergent powder industry, is the total weight percentage of SiO2 and Na2O in the sodium silicate solution, which is obtained by sodium silicate analysis. Coming.

    By increasing the amount of solids in the solution, naturally, the solution becomes thicker and the fluid becomes more viscous, but this viscosity change is not the same for different ratios. For example, having two identical concentrations of sodium silicate ratio 2 and 3.3, we increase the concentration by the same amount, the changes in the viscosity of the ratio are higher, faster and more. This is a very important point in choosing sodium silicate in the application of adhesion in various processes.

    Na2O percentage: This percentage determines the alkalinity of the sodium silicate solution, so that with the increase of this percentage, the alkalinity of the solution increases and its pH is higher. Determining the percentage of Na2O is done by titrating the solution with hydrochloric acid of one normality or with a lower normality.

    Note that although the acid normality standard is specified as one, the lower the acid normality, the more accurately the color determination point is determined and the higher the accuracy of the test.

    SiO2 percentage: This percentage represents the buffering properties of the solution, and the higher its percentage in the same ratio, the greater the solution's resistance to pH reduction. The high percentage of SiO2 is a very important point in cases where the buffering properties of silicate are important. It should be noted that with the increase in the concentration of SiO2, while keeping the concentration of Na2O constant, the ratio increases and the possibility of the formation of silicate chains or cyclic compounds increases. The method of determining the concentration of SiO2 is calculated by three methods of back titration, followed by the titration of calculating the percentage of Na2O, gravimetric or nemograph of sodium silicate solution, which is explained in the full sodium silicate analysis method.

    Density or volume of sodium silicate: The density of sodium silicate, which has been wrongly popularized, is actually the specific volumetric mass of sodium silicate. It is obtained by dividing the density of sodium silicate by the density of distilled water at any location. The specific volumetric mass is one of the most important items in the qualitative analysis of sodium silicate, which is usually measured using a hydrometer or a hydrometer. The standard temperature for measuring the volumetric mass of sodium silicate is at 20 degrees Celsius. To measure, first, the solution should be brought to a temperature of 20 degrees Celsius in a cold or hot water bath and measured with a hydrometer, or the temperature should be corrected using the table below.

    Baume is actually a unit of specific volumetric mass, which is obtained by the relation of specific volumetric mass

    Boom = (specific volumetric mass)/145-145

    And if the measurement is done using a barometer, the specific volumetric mass is calculated from the following relationship

    Specific volumetric mass = (bome_145) (145)/
