20um Sintered Stainless Steel Filter Cartridge For Fine Chemicals

20um Sintered Stainless Steel Filter Cartridge For Fine Chemicals

1. Manufacturing description 
Stainless steel sintered porous material is stainless steel 304, 304L, 316, 316L powder as the raw material, after screening, molding, sintering microporous material.​

Feature: Stainless steel sintered porous material has excellent corrosion resistance, oxidation resistance, wear resistance and mechanical properties.

The working pressure should not exceed the rated working pressure in use.

2 normal use, at least 3-5 minutes of low pressure start time, the relative pressure difference should be controlled below 0.5Mpa, and then gradually adjust the working pressure to the normal needs (the highest pressure does not exceed 0.4Mpa).

3. After the product runs to a certain period, it may increase the pressure and decrease the flow due to the blockage of the filter element, which requires recoiling or backwashing for regeneration.The regeneration period depends on the rated pressure and flow rate.

2. Specification of stainless steel sintered porous materials

3. Properties of stainless steel sintered porous materials:

• High-temperature resistance, in normal use under 500 ℃.
• High mechanical strength, good plasticity, can be machined.
• Corrosion resistance, oxidation resistance, can be used in nitric acid, sulfuric acid, dilute hydrochloric acid (5%), acetic acid, liquid hydrogen, liquid nitrogen environment.
• Good molding process, according to customer drawings for processing a molding.
• High filtration precision and good purification effect.
• The pores are uniform, the internal structure is stable, and no particles fall off.
• Good air permeability, easy to back blow cleaning, can be used repeatedly online regeneration.
• Wear resistance and impact resistance, good mechanical properties.

4.Application feilds of stainless steel sintered porous filter materials

According to its physical and structural characteristics, stainless steel sintered porous materials are mostly used in the fields of noise elimination, filtration and separation, fluid distribution, flow limiting, capillary core and so on.

• Chemical raw material production process in addition to impurity filtration, material decarburization filtration and fine filtration.
• Ultrafiltration, RO, EDI system security filtration in water treatment.
• Food and beverage industry finished product clarification filtration.
• Filtration and recovery of precious metal catalyst in petrochemical industry.
• Precision filtration of liquid raw materials, products and pharmaceutical intermediates in the chemical industry.
• Reverse osmosis security filtration in the field of water injection filtration.
• Gas purification of steam, compressed air deoiling purification.
• Medium purification and flow limitation for pneumatic components, lubricants, fuels and hydraulic pressure systems.
• Chemical dye industry of high - temperature decarburization.

5. Method for cleaning stainless steel sintered porous materials

• The decarbonization filter elements in the pharmaceutical and chemical industries are mainly back blown and backwashed, and the ultrasonic cleaning is the best.
• The filter elements of water industry are mainly rinsed with 5% concentration of nitric acid.
• According to the chemical properties of the filtered impurities, the filter elements of the original liquid shall be respectively soaked in pickling (5% nitric acid) or alkaline washing (3-5% sodium hydroxide) and then washed with ultrasonic cleaning.
