04 1月 China Ceramic Filter For Foundry
China Ceramic Filter For Foundry is composed of open micropores with uniform pore size distribution and connected to each other. When the fluid passes through these micropores, the suspended matter in the fluid, colloidal particles, polymer organic matter, etc. are captured or absorbed in the micropores inside the road, so as to achieve the effect of purification and uniform filtration.
China Ceramic Filter For Foundry has high strength, wear resistance, high temperature resistance, corrosion resistance, no pollution, uniform pore size distribution, long service life, simple regeneration, and is used for aluminum liquid filtration and solid-liquid separation.
Ceramic Filter For Foundry transmittance
Light transmittance refers to the effective filter area of the ceramic filter plate product. The higher the light transmittance, the fewer blind holes, the more effective the filter hole (display hole), and the better the filter effect.
Place the ceramic filter to be tested on a light box with a built-in 200W incandescent bulb, and use a 5.0 x 5.0 mm square transparent plastic plate to determine the area of the transparent filter. The rate method determines the transmittance of the filter. In this standard, the light transmittance (pass rate) of the filter is specified as 95% or higher.
Porosity of Ceramic Filter For Foundry
Porosity refers to the percentage of the total volume of pores in the filter plate product relative to the total volume of the filter plate product. The porosity determines the filtration capacity per unit volume of the foam ceramic filter plate. The greater the porosity, the greater the flow rate of the filter plate, and the better the filtering effect. The stronger the ability, and vice versa.
Porosity uniformity of Ceramic Filter For Foundry
Hole size uniformity is used to describe the difference between the actual number of holes per 25.4mm length and the theoretical number of holes required for the filter plate product. The smaller the gap, the better the product quality. If the gap is too large, the ability of the filter plate product to capture impurities is reduced or the melt filtering speed is too slow, which cannot meet the individual requirements of users. The uniformity of the pore size mainly depends on the foam used to produce the filter plate. The pore uniformity of the foam is good, and the pore uniformity of the filter plate is good, so the choice of foam is very important.
Product advantages of China Ceramic Filter For Foundry
1. Adsorption principle filtration can effectively remove large inclusions in molten aluminum, and can effectively absorb small amounts of small inclusions, and the filtration accuracy of the same mesh size is high;
2. No slag, effectively reducing the pollution of molten aluminum;
3. Molten metal has good thermal shock resistance and corrosion resistance;
4. Automatic assembly line production, three calibration procedures, accurate size, more in line with the filter box;
5. Improve surface quality, improve product performance, and improve microstructure.
During transportation and use of the filter plate, the filter plate must be able to withstand a certain external pressure. Therefore, this standard also introduces the compressive strength index as one of the basis for measuring the quality of the filter plate. The higher the compressive strength, the more durable the product and the better the quality, and vice versa.
This standard specifies that the compressive strength index should be above 0.5MPa.
