The main filter material of multi-layer sintered screen filter element adopts standard five-layer sintered screen. The standard five-layer sintered screen is made of five layers of stainless steel wire mesh by superposition and vacuum sintering. The filter element made of it has the characteristics of corrosion resistance, good permeability, high strength, easy cleaning and backwashing, accurate filtering accuracy, clean filter material, and non-falling of the screen. Multi-layer sintered mesh filter element has excellent filtration accuracy, filtration resistance, mechanical strength, wear resistance, heat resistance and processability due to its ability to reasonably match and design the pore size, permeability and strength characteristics of the material. Its comprehensive performance is obviously superior to other types of filtration materials.

Main features

1. Standard five-layer screen: composed of protective layer, filter layer, separation layer and two-layer support layer;

2. High strength and good rigidity: high mechanical strength and compressive strength;

3. High precision, uniform and stable: uniform and consistent filtration performance can be achieved for filtration particle size with nominal precision of 1~300um, and the mesh does not change during use;

4. The application environment is wide and can be used from 200. c～650。 C temperature environment and acid-base corrosion environment filtration;

5. Excellent cleaning performance: countercurrent cleaning effect is good, can be used repeatedly, and has a long service life (countercurrent water, filtrate, ultrasonic, dissolution, baking and other methods can be used for cleaning).

 Main application

1. Filtration of various high-temperature, corrosive liquids and catalysts in the petrochemical industry;

2. Filtration and purification of various polymer solutions in the chemical fiber film industry;

3. Filtration and separation of various catalysts in the pharmaceutical industry;

4. Used for gas distribution, liquid bed orifice material;

5. Used for high-pressure backwash oil filter, etc.

Advantages

1. Multi-layer sintered screen filter element has high temperature resistance, corrosion resistance and high filtration accuracy. It can continuously filter under the temperature of - 200 ℃ - 600 ℃ in the acid and alkali environment, and can play a uniform filtration accuracy of 1-200um;

2. The strength of multi-layer sintered screen filter element is high. After sintering, the multi-layer sintered screen has extremely high mechanical strength and compressive strength; It can flow in gradient less than the quiet angle, and some powders can flow in reverse gradient;

3. The multi-layer sintered screen filter element is easy to clean. Because of the surface filtration with countercurrent cleaning effect, the countercurrent cleaning effect is better, can be used repeatedly, and has a long service life. Easy to process and form, good weldability.

4. Multi-layer metal sintered mesh filter element is mostly used for the separation and filtration of gas or liquid, and is conducive to the recovery of solid particles. At the same time, the high temperature resistance of the six-layer sintered mesh also makes it possible to use it in a high temperature environment, and can control the distribution of air flow and eliminate noise, so it will not pollute the surrounding environment.
