Shanghai Wuyan "Metal Sintered Filter Cartridge, filter cartridge forms: metal powder sintering, multi-layer wire mesh sintering, metal felt sintering. Powder sintering is divided into titanium powder or 316L powder sintering, with high filtration accuracy, high temperature resistance, and renewable use of filter cartridges.

Titanium filter cartridge (powder sintered)

Titanium filter cartridges (including tube and plate types) are made from industrial high-purity titanium powder (grade 0) as raw material, and are sintered under high pressure and high temperature. Due to exquisite production techniques and special manufacturing processes, as well as the performance characteristics of titanium itself, titanium metal powder sintered filter cartridges have excellent performance:

1. Uniform structure, narrow pore size distribution, and high separation efficiency.‍

2. High porosity, low filtration resistance, and high permeation efficiency.

3. Resistant to high temperatures, it can generally be used normally below 280 degrees Celsius in a wet state.

4. Good chemical stability, acid and alkali corrosion resistance, and antioxidant properties. (For detailed corrosion resistance information, please refer to the attached table)

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

6. No particle shedding, no secondary pollution of the original solution, in compliance with food hygiene and pharmaceutical GMP requirements.

7. Strong antimicrobial ability and does not interact with microorganisms.

8. Can be regenerated online, easy to clean, and has a long service life (usually several times that of membrane filters)

Five layer sintered mesh

Five layer metal sintered mesh is made by arranging metal mesh with different wire diameters and mesh sizes in a certain order and sintering them at high temperature. Five layer metal sintered mesh has higher strength than stainless steel fiber felt, better permeability than metal powder products, uniform pore size distribution, high temperature resistance, weldability, renewability, and long service life. Five layer metal sintered mesh is easy to form and weld, and can be processed into various forms of filter elements such as circular, cylindrical, conical, etc.

Stainless steel fiber felt

Stainless steel fiber felt has excellent filtration performance and is an ideal filter material with high temperature resistance, corrosion resistance, and high precision. Stainless steel fiber felt is made by using extremely fine metal fibers (with diameters precise to micrometers) through non-woven paving, stacking, and high-temperature sintering. Stainless steel fiber felt is formed by layers of different pore sizes to form a three-dimensional porous structure, which has the characteristics of high porosity, large specific surface area, uniform pore size distribution, high pollutant holding capacity, and high filtration accuracy. Due to the above structure and characteristics, stainless steel fiber felt can effectively compensate for the weak points of metal mesh blockage and vulnerability, and can make up for the shortcomings of powder filtration products such as fragility and low flow rate. It has the characteristics of temperature and pressure resistance that ordinary filter paper and filter cloth cannot match. Therefore, stainless steel fiber felt is an ideal filter material with high temperature resistance, corrosion resistance, and high precision.

Metal wave filter cartridge

Metal wave filter element is a type of filter element made from metal fiber sintered felt and metal wire mesh as raw materials, and processed through special wave bending and high-precision welding.
