💖Welcome to visit, be sure to communicate clearly with the customer service before shooting whether you need 10PPI or 20PPI or other PPI, the product has a selection range of 10ppi coarse porosity to 60ppi, and explain the quantity, there will be obvious discounts after the quantity is large, be sure to communicate well in advance! Also welcome to customize other PPI number, size, material, shape of foam ceramics! Foam ceramics can be used in various fields such as filtration, high temperature combustion, catalysis, etc. If it is used in scientific research such as combustion, welcome to exchange specific scenes and parameters, thank you!
💖Foam ceramics is a new type of industrial ceramic products with three-dimensional network skeleton structure, with low bulk density (0.25-0.65)g/cm' and high porosity (80-90)%. Due to the high temperature and chemical corrosion resistance of these products and the large specific surface area of the cavity through each other, they are widely used in metal melt filtration, high temperature flue gas purification treatment, chemical filtration, carrier and photothermal conversion and other fields, especially metal melt filtration, which can significantly reduce the casting scrap rate, improve the mechanical properties of casting parts, and reduce the comprehensive cost.
💖Classification of foam ceramics:Foam ceramics can be divided into silicon carbide foam ceramics, alumina foam ceramics, zirconia foam ceramics, magnesium oxide foam ceramics and so on.
💖Product features :1, reduce the degree of inclusion defects, reduce porosity defects. 2, improve the machining performance of casting and casting process yield. 3, high high temperature working intensity, thermal shock resistance and metal flow impact resistance. 4, reduce processing time and tool damage, high dimensional accuracy. 5, simplify the pouring system, improve the utilization rate of the template.
💖Product use method: A. Place in a sprue cup or straight to the bottom of the sprue. b, placed horizontally in the runner, so that the metal liquid filling smooth, to avoid the direct impact on the filter or vertical placed in the runner, the metal liquid flow rate is fast, has a good filling ability. c, the size of the filter should be determined according to the shape and melting factors and the characteristics of the filter itself. d, should try to control the casting head to reduce the impact of metal liquid on the filter. e, the filter should not be used over temperature. f, avoid using filter to control the casting speed.
💖Foam ceramic selection guide: It is very important to correctly select and design the filter type and filter holder according to the type of casting and pouring weight. The general principle is that the entire pouring system is a pressure-free system to ensure the smooth filling of liquid metal, and the main points are (ratio of cross-sectional area): F straight runner :F filter front end :F filter back end :F cross runner :F inner runner =1:4:1.75:1.1:1.2
💖Storage method: Store in a dry and ventilated place, free from rain and heavy pressure.
