advantages
HUAhANG


Corrosion resistance and high temperature resistance: The filter element is made of 304 stainless steel material, which has excellent corrosion resistance and high temperature resistance. It can maintain stability in chemical media such as acid, alkali, salt, etc., and is suitable for various complex environments.

High strength and wear resistance: 304 stainless steel has high strength and hardness, can withstand high pressure, is not easy to break or deform, and ensures long-term stable filtration effect.

Good filtration performance: This filter cartridge exhibits uniform surface filtration performance for filtration particle sizes ranging from 2-200um, effectively removing impurities, particulate matter, and suspended solids from water.

Easy to clean and maintain: The design is simple, easy to disassemble and clean, which can effectively reduce maintenance workload. Its smooth surface is less prone to dirt and impurities, extending its service life.

Wide application areas: 304 stainless steel mesh basket filter is widely used in water treatment, chemical industry, petrochemical industry, electronics industry, automotive industry and other fields, ensuring the purity and safety of various industries





                       production process


Material selection and pretreatment
1. Substrate selection:
304, 316, or 316L stainless steel material is selected, which has a corrosion resistance of 18% chromium and 8% nickel content, and can withstand working temperatures from -196 ℃ to 800 ℃.

2.Silk processing:
Straighten the silk material, eliminate raw material bending, and ensure weaving or welding accuracy
Surface acid washing removes oxide scale and oil stains, improving the quality of subsequent processing.

Filter forming process
1. Weaving/Welding Forming:
Weaving method: Using plain weave, diagonal weave and other weaving methods, controlling the wire diameter (0.1-2mm) to form a uniform mesh structure with a pore size of 5 μ m-5mm;
Welding method: The coarse wire mesh material is fixed by argon arc welding or resistance welding to form a high-strength mesh structure.

2. Sintering process (optional): Multiple layers of stainless steel mesh are laminated and pressed, and then vacuum sintered to form a sintered mesh with a gradient filtering structure.
Filter structure processing
1. Wave bending treatment: The filter screen and support layer (galvanized mesh or copper mesh) are processed into a corrugated shape by a wave bending machine, increasing the effective filtration area by 30% -50%.

2. Skeleton assembly:
Choose stainless steel or plastic frame as the core support
Adjust the thickness and aperture of the skeleton according to pressure requirements to prevent deformation of the filter material.

3. End cap welding:
Using argon gas shielded welding technology, the filter screen is precisely welded to the stainless steel end cap
Key control of welding temperature to prevent burning through of filter material 56.

Post processing and detection
1. Surface treatment:
Electrolytic polishing improves surface smoothness
Spraying PTFE coating enhances wear resistance.
2. Performance testing:
Microscopic detection of aperture uniformity (error ≤± 5%)
Simulate working conditions to test filtration efficiency and pressure drop
Salt spray test to verify corrosion resistance (ASTM B117 standard).

Finished product packaging
Using anti rust oil spraying and cushioning material packaging, accompanied by material certification and testing report delivery

Dissolve potassium dichromate or crystals in water to 60 to 80 degrees, and slowly add concentrated sulfuric acid with a concentration of 94% until sufficient. Add slowly and stir. Add up to 1200 milliliters of potassium sulfate or completely dissolve, and the solution will appear dark red in color. At this time, the rate of adding concentrated sulfuric acid can be accelerated until it is completely added. If there are still undissolved crystals after adding concentrated sulfuric acid, they can be heated until dissolved. The function of cleaning solution is to remove general pollutants, grease, and metal particle impurities on the wall of stainless steel filter cartridge, and it can effectively kill the bacteria and microorganisms that grow on the filter cartridge and damage the heat source. If the filter element has been alkaline washed before, the alkaline solution must be washed first, otherwise fatty acids will precipitate and contaminate the filter element.
