Microporous Stainless Steel Powder sintering filter is a selection of high purity up to 99.96% purity powder after molding, and then send people constant temperature high temperature sintering furnace for high temperature sintering, particles by uniform high temperature, physical traits change and natural bonding together composed of microporous filter components.
　　Metal sintering FilterGood or bad determination can first be determined from the surface, high-quality, high-purity powder sintering filter, the surface is a granular sense, with sub-light metal native color, particles between the appearance of uniform pores, contact is not smooth, residual, increase the adhesive filter surface will appear smooth light metal color,
Metal sintering Filter because its spongy body is not very good, so in the sintering process, temperature control is a very important step, must have a professional personnel to operate.

High-quality high-efficiency microporous stainless Steel Powder sintering filter cartridge can be cleaned back and reused, supply the following cleaning methods:
1, pharmaceutical and chemical fields of decarbonization filtration, to often choose anti-blowing, anti-scour methods and combined with ultrasonic cleaning effect.
2, water industry, because the filter surface interception is mostly non-water-soluble salts and oxides, generally choose 5% of nitric acid soaking, without ultrasonic cleaning, you can reach the cleaning effect.
3, the original liquid filtration, to combine the chemical properties of pollutants, respectively, choose the following methods for cleaning:
(1) Alkali washing: With 3-5% hydrogen hydroxide analysis of pure solution immersion for 30-60 minutes, temperature of about 40 degrees, in the ultrasonic cleaning machine cleaning. After soaking with filter deionized water or injection water table punch, measure the conductivity. Blow dry with pure air ≥0.4mpa pressure.
(2) Pickling: Soak with 5% nitrate solution for more than 8 hours, the temperature is about 40 degrees. Wash in ultrasonic cleaning machine. After soaking with filter deionized water or injection water table scour corrosive, lateral conductivity. Blow dry with pure air ≥0.4mpa pressure.
(3) Organic pollution can be combined with surfactant cleaning, cell debris pollution system combined with enzyme cleaning effect is more ideal (food and beverage can choose high concentration citric acid cleaning).
(4) The above methods can be used alone, but also can be combined with each other to replace the use. If there are conditions, combined with ultrasonic cleaning machine effect. Note: To often online anti-blowing (online cleaning with pure compressed air or filter liquid or clean water recoil), you can reduce the number of times to clean with the above method.
