Solid sodium silicate has many applications in the washing industry

Solid sodium silicate has many applications in the washing industry, mainly including the following aspects:

Washing aid

Emulsification and dispersion of dirt: The aqueous solution of sodium silicate has the ability to emulsify, disperse and suspend dirt and solid particles, and can evenly disperse dirt particles such as oil and dust in the detergent, preventing dirt from re-depositing on clothes or washed items, thereby improving the washing effect.

Softening water: Sodium silicate can form insoluble salts with heavy metal ions such as calcium and magnesium in water, reduce the hardness of water, reduce the impact of calcium and magnesium ions on the active ingredients of detergents, make detergents work better, improve washing efficiency, and prevent the formation of scale marks on the surface of fabrics.

Stabilization and buffering effect

Stabilizing foam: It plays a role in stabilizing foam in detergents, making the foam rich and lasting, which helps to improve the decontamination ability and cleaning effect during the washing process, and also increases the user’s washing experience.

pH buffering: The aqueous solution of sodium silicate is alkaline, which can buffer the pH value of the solution during the washing process, so that the pH value of the washing liquid is kept within an appropriate range, which can not only enhance the detergent’s ability to remove acidic stains, but also save the amount of surfactant in the detergent.

Protective effect

Prevent metal corrosion: It has a certain anti-corrosion effect on the metal surface, which can prevent other ingredients in the detergent from corroding metal parts such as washing machines, extend the service life of equipment such as washing machines, and also protect the metal surface for the cleaning of some metal products.
Protect fabric fibers: During the washing process, sodium silicate can form a protective film on the surface of fabric fibers, reduce the damage of detergents to fibers, make the fabric softer and smoother, and maintain the color and strength of the fabric.

As a filler

Reduce costs: Sodium silicate can be used as a filler for detergents. Without affecting the washing effect, it can reduce the amount of active ingredients in the detergent, thereby reducing the cost of the product and improving the market competitiveness of the product.

Improve product performance: It can keep the powdered detergent product loose and prevent agglomeration, making it easier to store and use. It can also keep the finished product at a higher moisture content to extend the shelf life of the product.
