Silicon Aluminum Powder For Glass Fiber
Product advantages
Silicon aluminum powder can replace zirconium silicate, significantly reducing costs. In architectural coatings, the amount of silicon aluminum powder used is generally 15-25% of the amount of titanium dioxide used, thereby significantly reducing product costs.
Silicon aluminum powder can significantly improve the performance of products. In architectural coatings, silicon aluminum powder can enhance titanium dioxide efficiency, improve product whiteness, dry film coverage, storage stability, weather resistance, wear resistance, and scrub resistance. In addition, silicon aluminum powder can improve the construction performance of the product, reduce the thermoplasticity of the coating, and improve the surface stickiness and dust absorption.
Silicon aluminum powder does not use high energy consuming processes such as calcination during the preparation process. The production process is simple and energy consumption is low. The produced silicon aluminum powder has low impurity content, large specific surface area, and large pore volume. In addition, silicon aluminum powder can maintain structural stability at high temperatures, has good electrical insulation performance and corrosion resistance, and is suitable for manufacturing corrosion-resistant materials and insulation materials.
Silicon aluminum powder is widely used in various fields, including architectural coatings, inks, plastics, ceramic glazes, rubber, leather, printing and dyeing, water treatment, and papermaking. In architectural coatings, silicon aluminum powder can have the same lifespan as buildings and has the advantages of natural and beautiful coating, fire resistance, waterproofing, breathability, aging resistance, non-toxic and harmless, low cost, and fast construction.
In summary, silicon aluminum powder has demonstrated significant advantages in multiple fields due to its cost-effectiveness, improved performance, and environmental characteristics.
Grinding treatment: Firstly, the lithium slag is ground to obtain grinding powder.
Weak magnetic separation treatment: The grinding powder is subjected to weak magnetic separation treatment to separate magnetic and non-magnetic materials.
Strong magnetic separation treatment: The material after weak magnetic separation is subjected to strong magnetic separation treatment to further separate magnetic and non-magnetic materials.
Concentrated filtration and flotation treatment: Concentrate and filter the material after strong magnetic separation, and then perform flotation treatment to obtain sulfur-containing tailings and flotation materials.
Add soluble carbonate: Add soluble carbonate to the flotation material, and obtain fine powder of pyrophyllite after secondary concentration and filtration.
The principle and purpose of lithium slag impurity removal: Lithium slag may contain other impurities that may affect the manufacturing process of glass fibers. Through the above steps, these impurities can be effectively removed to ensure that the metal element composition in lithium slag meets the requirements of glass fiber manufacturing.
