Ceramic filter plate are key components of ceramic filter plate, belong to the function of porous ceramics new material, it was full of crisscross, mutual penetration of capillary hole (diameter 1.5 meters or so), due to capillary action, ceramic filter plate after contact liquid separation pulp in the absence of external force automatically into the pore channels, solid was blocked filter plate surface.

The overall structure of the ceramic filter plate is the two common structures of the production formula based on corundum, including raw material grade, finishing, mixing and high-precision molding, segmented high-temperature sintering, multiple coating of the functional layer, cleaning the filter, shaping the combination, performance inspection, packaging and storage processes.

Sintering production of ceramic filter plate adopts sintering layer coating technology many times, the microporous layer is obvious, small inside and outside, filter plate regeneration resistance is small, easy to clean, surface layer strength is high, wear resistance. The two single blocks are bonded together with imported epoxy adhesive, with high bonding strength and corrosion resistance.

Filter material has two kinds of ptfe and stainless steel, ptfe filter tube toughness is good, help to improve the overall temperature difference and deformation capacity of the filter plate. Stainless steel filtration strength, poor deformation resistance. Users can choose according to the environment.

At present, the varieties of ceramic filter plate on the market are relatively mixed, silicon carbide formula production of filter plate silicon carbide crystal type is irregular, the filter plate hole is irregular, it is difficult to clean when plugging, in addition, silicon carbide main material ceramic filter plate brittle wear resistance is poor, refractory intolerance. Using two single sintered ceramic filter plates, sintering times reduced, production process reduced, productivity increased, production cost greatly reduced, but due to low bonding strength, backwash pressure can not exceed 0.09mpa.

Seriously affect the cleaning and regeneration effect of ceramic filter plate, reduce the speed of equipment production capacity, in practical application, use more equipment, increase the user's project investment and production and operation cost.

The application of ceramic filter plate in iron, copper, lead, zinc, iron, silver, sulfur, gold and other dressing plants has proved that the filter plate has high strength and is easy to clean and regenerate. The backwash pressure of the filter plate can reach 0.3mpa, which improves the backwash and joint cleaning effect of the filter plate. The production index is greatly improved, and its service life can reach more than 2 years. Saves user investment and production and operation cost.

What is the compressive strength of ceramic filter plate?

In the process of transportation and use of the filter plate, the filter plate has to bear the impact of a certain pressure from the outside world, so the standard has also introduced the compression strength index, which helps to measure the quality of the filter plate. The higher the compression strength, the higher the durability of the product, the better the quality, and vice versa.

The standard sets the compressive strength above 0.5MPa.
