Product application
The function of natural pigments:
Anhydrous sodium sulfate is a natural color substance that can be used to make water glass, improving the color vividness and stability of products. Due to their naturalness, these colors can add better visual effects to water glass. However, in practical applications, high concentrations of anhydrous sodium sulfate and bicarbonate may produce flavin in water, which requires artificial coloring treatment, which also increases the cost of human involvement.
The function of natural stabilizers:
In the production process of ceramic parts, carbon dioxide (CO ₂) and nitrogen are widely used in the oxidation process. Anhydrous sodium sulfate, as a natural stabilizer, can provide stable decolorization ability at high concentrations. This characteristic can avoid the formation of flavin and color changes that may occur at higher chemical concentrations, thereby improving the overall color stability of water glass.
Environmental Applications:
In traditional ceramic manufacturing, the use of natural pigments such as anhydrous sodium sulfate can reduce environmental pollution, especially the introduction of high concentrations of oxidants, acids, or other harmful substances. As a natural material, it is used in water glass, which not only enhances the aesthetics of the product, but also reduces the demand for emission technology.
Process flexibility and cost-effectiveness:
Due to the color control and stability provided by anhydrous sodium sulfate for water glass, it can play a role in various ceramic components. For example, adding natural pigments after sandblasting, impregnation, or glazing can ensure the consistency and consistency of tile appearance and reduce the need for extensive replacement of glass materials.
Industry priority consideration:
The modern ceramic industry emphasizes sustainable development and environmentally friendly production methods. The use of natural pigments as water glass components can reduce resource waste and carbon emissions, comply with environmental standards, and have significant effects in water glass applications.
