Product Details

Zhengxing® sintered metal powder filter

Zhengxing® sintered metal powder filter

Raw Material

Stainless steel of 316/316L, 304;

Filter Rating

0.2-200 micron

Characteristic

It is manufactured by static pressing. The pore size can be adjusted by suitable selection of the powder size fraction and the process parameters. Various of size and can make according your requirement.

Application

Gas and liquid filtration, solid catalyst recovery, filtration of slurry oil and other petrochemical products, high-temperature gas filtration, fluidization, powder conveying, sparging and other applications in various industrial fields.

Product Features:

1 high precision filter: pore stability, will not change the pore pressure changes with the phenomenon. Can effectively remove suspended solids and particulates, excellent filtration, purification effect.

2 permeability, pressure loss is small. Filter composed entirely of spherical powder, high porosity, pore size uniformity and smooth, the initial resistance is small, easy cleaning, regeneration ability, long service life.

3 high mechanical strength, good rigidity, good plasticity, anti-oxidation, corrosion protection without additional framework support, installation and use, easy maintenance, assembly, and can be welding, bonding and mechanical processing.

4 uniform porosity, especially for fluid distribution, homogenization treatment uniformity requirements of the occasion.

5 forming a copper powder products, without cutting, effective utilization of raw materials is high, maximum material savings.

6 Filtration: 0.2μm ~ 50μm.

Applications:

Mainly used in petroleum, chemical, automotive, aircraft, marine industrial filtration gases, liquids, fuel oil, also used extensively for pneumatic, hydraulic circuit filter elements.

Main Application

1. Polyester melt purification in chemical fiber and membrane industries.

2. High temperature filtration and corrosion liquid filtration in petroleum.

3. Hydraulic fuel and lubrication oil filtration in mechanical equipment.

4. Liquid purification in pharmaceutical, biological and beverage industries.
