Product Description

Product Description

High-Performance Zirconia Ceramic Filter Plates

Our Zirconia (ZrO2) ceramic filter plates are manufactured using a unique process, resulting in a product with high porosity, a uniform pore size distribution, and excellent mechanical strength. These filter plates are specifically designed for precision filtration in high-temperature, high-pressure, and corrosive environments. They efficiently remove micron-sized impurities from liquids or gases, ensuring the purity of the filtered medium.

Specification

Zirconia Ceramic Filter Advantages

Superior Corrosion Resistance: Highly resistant to a wide range of chemical media, including acids, alkalis, and salts, making them suitable for harsh chemical environments.

High Mechanical Strength: Maintains excellent flexural and compressive strength even at high temperatures, resisting cracking and breakage.       

High-Temperature Resistance: Usable at temperatures exceeding 1200°C, ideal for high-temperature filtration applications.

Uniform Pore Structure: Ensures efficient and stable filtration performance. Various pore sizes are available.

Good Biocompatibility: Suitable for special filtration needs in the medical and food industries.

Products Usage

Selection of pore size: When using a filter, the pore size of the filter (number of pores per inch of product, PPI) must be determined based on the casting material, casting size, pouring temperature, and the number of inclusions in the molten metal; The pore diameters are mainly: coarse pores (10PPI, 15PPI), intermediate pores (20PPI), and fine pores (25PPI, 30PPI). Ductile iron parts generally use 10 PPl or 15 PP products, gray iron and copper castings generally use 15 PPI or 20 PPI products, and aluminum alloy castings generally use 20 PPI or 30 PPI products.

Size selection: The greater the thickness of the foam ceramic filter, the better the strength of the filter and the higher the filtration efficiency of the filter, but the higher the cost of use. Considering the most suitable strength and filtration efficiency, the general recommendations are as follows: Size: 40MM~75MM, Thickness: 15MM~22MM Size: 75MM-120MM, Thickness: 22MM~25MM Size: 120MM~150MM, Thickness: 25MM~30MM Size: > 150MM, thickness 30MM~40MM

Filtration capacity: The filtration capacity per unit area of the filter generally does not exceed: gray cast iron 1.5-2kg/cm², ductile iron 1-1.5kg/cm² (due to differences in casting system processes, try to design with the lower limit value to increase the insurance factor) .

Filter area: The cross-sectional area of the sprue where the filter is placed should be appropriately expanded. Generally, the cross-sectional area of the normal sprue is 2 to 4 times.

Placement location: The foam ceramic filter can be placed in various parts of the pouring system. It should be selected according to the characteristics of the parts and production conditions, and should be as close as possible to the casting to achieve the best filtration effect. In practical applications, according to different castings and requirements.

Applications

Chemical & Pharmaceutical Industries: Used for filtering acid-alkali solutions, catalyst recovery, and fine chemical purification.

Metallurgy & Foundry: 
Filters non-metallic inclusions from molten metals (e.g., steel, aluminum, copper) to improve casting quality.

Environmental Protection: Applied in flue gas dust removal, exhaust gas purification, wastewater treatment, and particulate filtration.

Food Industry: Filters edible oils, beverages, and syrups to ensure product purity.

Medical Devices: Used in precision filtration equipment for applications like hemodialysis and cell separation.
