What is Diatomite Filter Aid?
Diatomite Filter Aid have good microporous structure, adsorption performance, and anti compression performance. They can not only achieve a good flow rate ratio for the filtered liquid, but also filter out fine suspended solids, ensuring clarity. Diatomaceous earth is a sediment of ancient single-cell diatom remains. Its characteristics include light weight, porosity, high strength, wear resistance, insulation, thermal insulation, adsorption, and filling, among other excellent properties.
Diatomaceous earth is a sediment of ancient single-cell diatom remains. Its characteristics include light weight, porosity, high strength, wear resistance, insulation, thermal insulation, adsorption, and filling, among other excellent properties. Has good chemical stability. It is an important industrial material for insulation, grinding, filtration, adsorption, anticoagulation, demolding, filling, and carrier. It can be widely used in industries such as metallurgy, chemical industry, electric power, agriculture, fertilizers, building materials and insulation products. It can also be used as industrial functional fillers for plastics, rubber, ceramics, papermaking, and other industries.
Classification
Diatomite Filter Aidare divided into dried products, calcined products, and flux calcined products according to different production processes.
①Dry products
Dry the purified, pre dried, and crushed silica dry soil raw materials at a temperature of 600-800 ° C, and then grind them into powder. This product has a very fine particle size and is suitable for precision filtration. It is often used in combination with other filter aids. Dry products are mostly light yellow, but also have milky white and light gray.
② Calcined product
The purified, dried, and crushed diatomaceous earth raw materials are fed into a rotary kiln, calcined at a temperature of 800-1200 ° C, and then crushed and graded to obtain the calcined product. Compared to dry products, calcined products have a permeability higher than three times. The calcined products are mostly light red in color.
③Flux calcined products
After purification, drying, and crushing, the diatomaceous earth raw material is added with a small amount of fluxing substances such as sodium carbonate and sodium chloride, and calcined at a temperature of 900-1200 ° C. After crushing and particle size grading, the flux calcined product is obtained. The permeability of the flux calcined product has significantly increased, more than 20 times that of the dry product. The calcined products with flux are mostly white in color, and when the Fe2O3 content is high or the flux dosage is low, they appear light pink.
