What is the role of sodium carbonate in laundry detergent

Sodium silicate is also known as sodium silicate, and its solution is also known as Paohua alkali. In the generation of washing powder, sodium silicate is a very important modifier, and it has a synergistic effect with other modifiers. The following washing powder OEM manufacturers specifically introduce the role of sodium carbonate in washing powder: (1) Adjustment. Sodium silicate is likely to keep the pH value of the aqueous solution unchanged, that is, there is an adjustment effect. It is very possible to persist in the alkalinity of the cleaning solution, thereby landing the usage of the detergent. (2) Effects on buoyancy, emulsion force and foam firmness. When the sodium silicate is dissolved in water, the magnesium chloride formed by the hydrolysis reaction produces a colloidal sealing glue group in the water, thereby improving the colloidal solution function of the cleaning solution and developing the detergency. It also has the effect of enhancing the emulsion strength of the cleaning solution and the firmness of the foam. (3) Harm to the properties of slurry and washing powder. In the process of slurry configuration, sodium silicate is likely to adjust the fluidity of the slurry, and it is also likely to strengthen the sodium tripolyphosphate so that it will not be converted into orthopolyphosphate. In the spray dryer, sodium silicate is likely to improve the compressive strength of the washing powder particles, the uniformity follows the desired flowability, improve the solubility of the finished product, prevent the washing powder from agglomerating and make the washing powder in a higher moisture content. stored under. (4) It has a certain maintenance effect on textiles. (5) Anti-rot effect. Sodium silicate can reasonably prevent the rot effect of sulfonate and polyphosphate on metal materials, especially for aluminum and copper. (6) The effect of combining with potassium carbonate. It works with potassium carbonate to soften temporary water hardness and remove magnesium salts from water.
