Products Description

The Porous titanium metal powder sintered filter element is the liquid state of titanium alloy qualified for metal smelting, which is atomized into powder by atomization, rotating electrode method or vacuum decompression atomization, and then hot extruded into rods and hot isostatic pressing to form titanium alloy turbine discs, aircraft keel joints or Materials made of seawater desalination units. It has high strength, good heat strength at medium temperature, corrosion resistance and rich resource reserves, so it is widely used in aviation industry, chemical industry, metallurgical industry, medical industry, marine engineering and so on.

The Porous titanium metal powder sintered filter element is a micro-filtration element formed by industrial high-purity titanium powder (purity ≥ 99.7%) as the main raw material, after sieving, cold isostatic pressing, later, sintering with high temperature and fine vacuum. Also called titanium rod filter element, titanium metal filter element, microporous titanium rod filter element, its structure is relatively uniform, and can be made into various required shapes by custom-made molds; there are a large number of open pores distributed on the surface of the material, and the pore diameter is uniform, so the porosity is high , the low filtration resistance, the material’s permeability is good, and it has excellent physical performance. It is similar to the stainless steel powder filter element that belongs to the metal powder sintered filter element, but it is easier to form and sinter, which is better than the stainless steel powder sintered filter element. In the high temperature environment of 300℃, its advantages are more obvious, and it can be widely used in the separation and purification of solid, liquid and gas in various media.

The Porous titanium metal powder sintered filter element is a new type of filter material and a filter element based on the science of inorganic materials. Its products are sintered into one shape without cutting. It has high filtration precision, good air permeability, high mechanical strength, and high material reuse rate. It is especially suitable for a large number of components with complex structures. Our company can produce titanium alloy metal powder sintered filter elements in various shapes, structures, particle sizes and filtration precisions according to user requirements, such as rod-shaped, tubular, sheet-shaped, cap-shaped, cap-shaped filter elements, etc. The main scope of application includes chemical industry, petrochemical industry, biological engineering, machinery industry, food industry, etc.

Products Performance

The porous titanium powder sintered filter element is made of high-purity industrial titanium powder as raw material, and is sintered at high pressure and high temperature. Due to the superb production technology and special production process and the performance characteristics of titanium raw materials, the titanium alloy powder sintered filter element has extremely good performance:

1. The overall structure is uniform, the surface pore size distribution is narrow, and the separation efficiency is high; the porosity is high, the surface pores are uniform and smooth, the initial resistance of the filter element is small, easy to blow back, and the service life is long, especially suitable for fluid distribution, homogenization treatment, etc. Industries that require high uniformity.

2. High filtration precision, good permeability and high efficiency. There is no phenomenon that the pore size changes with the change of pressure. It can effectively remove suspended solids and particles in the medium.

3. High temperature resistance, generally can work and use normally below 300℃.

4. Good chemical properties, high stability, acid and alkali corrosion resistance, and high oxidation resistance. It can be used in a large pH environment, suitable for a variety of working environments.

5. No particles fall off, and will not cause secondary pollution to the original solution, which meets the requirements of food hygiene and pharmaceutical GMP grades.

6. It has good mechanical properties, high rigidity, and strong plasticity. It can be used for pressure filtration and suction filtration, and is easy to operate. There is no need to increase the protection of the outer skeleton, and the operation and maintenance are convenient.

7. Low pressure difference, small footprint, large flow rate, 0.2 MPa can reach large flow rate.

8. It has strong anti-microbial ability and will not interact with microorganisms, so it can be applied to bioengineering and other fields.

9. The molding process is good, and the length of one-piece molding without welding can reach 1000mm.

10. It can be regenerated online, easy to clean repeatedly, and has a long service life. The normal service life is more than 3 years. (Generally several times the life of the membrane filter)

11. The powder sintered product is formed at one time, no need to cut it, and it is easy to process. Suitable for components with large quantities and complex structures, low cost and good effect.

12. It is non-magnetic and non-toxic, and has good compatibility with human tissue and blood, so it is widely used in pharmaceutical factories, food industry and water treatment industry.
