sodium tripolyphosphate is widely used in the construction and sanitary ceramics industry, such as mud, grinding, glaze and other processes, can reduce the viscosity of the mud, improve the fluidity of the mud, reduce the moisture content of the mud, thereby reducing the energy consumption of the ball mill and spray drying tower, improve the quality, and can make the powder particle size distribution more reasonable, improve the comprehensive performance of the powder.
Product Features:
white granular or powder, performance density 0.6-0.9 g/cm3, melting point 622 ° C, soluble in water, alkaline aqueous solution.
Product Application:
added together with mud or glaze and water into a ball mill for ball milling, and the addition amount is generally 0.1-0.3% of the dry material amount. It is recommended to conduct a series of laboratory tests before use in order to find out the proportion more suitable for large-scale production.
packaging specifications and instructions:The net content of each bag is 25KG or 50KG, and the packaging method can also be determined through negotiation according to customer requirements.
