Anti-caking agent Sodium aluminosilicateSodium aluminate, also known as sodium silicate or bubble alkali, is an inorganic non-metallic material, which is widely used in construction, petroleum, chemical, textile, papermaking, electronics and other fields. It has excellent heat resistance, acid resistance, weather resistance and anti-aging properties, so it has been widely used in these fields.
1. Preparation of sodium aluminosilicate.
There are two main methods for the preparation of sodium aluminosilicate: dry and wet. The dry process is to mix sodium silicate and alumina powder in a certain proportion and react at high temperature to generate sodium silicate. The wet process is to dissolve sodium silicate and alumina powder in water, and then prepare sodium aluminosilicate through precipitation, filtration, drying and other steps.
Second, the application of sodium aluminosilicate.
1.Architectural field.
Sodium aluminosilicate is mainly used as a gelling agent and reinforcing agent in the construction field. It can improve the strength, durability and impermeability of concrete, and prolong the service life of buildings. In addition, sodium aluminosilicate can also be used in the production of waterproof coatings, tile adhesives and other building materials.
2.Petrochemical industry.
Sodium aluminosilicate is mainly used as a catalyst carrier and separating agent in the petrochemical industry. It can improve the activity, stability and selectivity of catalysts, thereby improving the yield and quality of petrochemical products. In addition, sodium aluminosilicate can also be used in the production of oilfield chemicals, water treatment agents, etc.
3.Textile field.
Sodium aluminosilicate is mainly used as a dye dispersant and stabilizer in the textile field. It can improve the dispersion and stability of the dye, thereby improving the quality and efficiency of the dyeing. In addition, sodium aluminosilicate can also be used in the production of fabric finishes, waterproofing agents, etc.
4.Papermaking field.
Sodium aluminosilicate is mainly used as a paper reinforcing agent and a waterproofing agent in the papermaking field. It can improve the strength and water resistance of the paper, which can improve the quality and service life of the paper. In addition, sodium aluminosilicate can also be used in the production of paper coating agents, paper adhesives, etc.
5.Electronics.
Sodium aluminosilicate is mainly used as a packaging material for electronic components in the electronics field. It can improve the insulation performance and heat resistance of electronic components, thereby improving the reliability and stability of electronic products. In addition, sodium aluminosilicate can also be used in the production of ceramic substrates, electronic pastes and other electronic materials.
3. Performance characteristics of sodium aluminosilicate.
1.Heat resistance: Sodium aluminosilicate has high thermal stability and can maintain good performance at high temperatures.
2.Acid resistance: Sodium aluminosilicate has good acid resistance and can maintain good performance in acidic environments.
3.Weather resistance: Sodium aluminosilicate has good weather resistance and can be used for a long time in outdoor environments.
4.Aging resistance: Sodium aluminosilicate has good aging resistance and can prolong the service life of buildings.
5.Non-toxic: Sodium aluminosilicate is a non-toxic and harmless material, which is harmless to the human body and the environment.
Fourth, summary. Sodium aluminosilicate is an important inorganic non-metallic material, which is widely used in construction, petroleum, chemical, textile, papermaking, electronics and other fields. It has excellent heat resistance, acid resistance, weather resistance and anti-aging properties, so it has been widely used in these fields. With the continuous development of science and technology, the application prospect of sodium aluminosilicate will be broader.
