PA PE Sintered Filter Elements for Metallurgy

                                        PA  PE Sintered Filter Elements for Metallurgy

The PA PE sintered filter elements are advanced filtration components designed for a wide range of industrial applications. The elements are composed of polyamide (PA) and polyethylene (PE) and offer excellent chemical resistance, thermal stability and mechanical strength. Their porous structure enables precise particle retention and efficient fluid flow, making them ideal for gas and Liquid Filtration in the pharmaceutical, food and beverage, chemical processing and water treatment industries. With its high dirt holding capacity and compatibility with corrosive liquids, PA PE sintered filter elements provide reliable and cost-effective filtration solutions for critical processes, ensuring product quality and process efficiency.

Features of PA  PE Sintered Filter Elements 

1. The sintered filter element is a new type of filter material made by vacuum sintering with high mechanical strength and overall rigidity.

2. Filter production: The wire mesh in the sintered mesh filter element is interlaced layer by layer to form a uniform and ideal filtration structure.

3. It has excellent filtration precision, filtration impedance, mechanical strength, wear resistance, heat resistance and processing performance.

4. The comprehensive performance of this sintered filter element is significantly better than other types of filter materials.

Working principles of PA  PE Sintered Filter Elements

Different liquids have different saturated vapor pressures. At a temperature of 70 degrees Celsius, water begins to boil at a pressure of about 30kPa, while oil boils at a low pressure of 5Pa. At the same temperature, the saturated vapor pressure of oil is much lower than that of water. Therefore, when the pressure on the oil surface is reduced to below the saturated vapor pressure of water by vacuuming, the water in the oil will vaporize violently and overflow from the oil in the form of steam. The oil enters the vacuum tank from the top and is sprayed downward through the nozzle with the help of vacuum suction. The water in the oil vaporizes in the vacuum chamber and is pumped out by the vacuum pump. The dehydrated oil is discharged from the bottom. The middle part of the vacuum chamber is filled with lipophilic material, which disperses the injected oil on the surface of the filling material to form a thin oil film, which increases the air-liquid interface area and prolongs the time for the oil to stay in the gas phase space.

Advantage of PA  PE Sintered Filter Elements 

1. Corrosion resistance: resistant to strong acid and alkali.

2. High strength and good toughness: The filter element is not easy to break, which solves the problem of "breakage" causing huge losses to manufacturers, which is unmatched by metal filter elements.

3. High filtration precision: The filtration precision of PTFE sintered filter elements can reach 0.3um, or even below 0.1um, which is beyond the reach of ordinary metal filter elements.

4. Smooth outer surface: The outer surface of the filter element is as smooth as "waxing", making it difficult for impurities to hang on the surface. At the same time, the filtration precision of the outer surface is high, and the filtration precision of the inner layer is low, making it difficult for impurities to embed in the filter element.
