Food Grade Stainless Steel 5Mpa Porous Metal Plate

The factory direct sale food grade stainless steel powder sintering filter material


  • Product introduction

The sintered metal powder filter element USES metal powder as the raw material, does not need to add adhesive. After cold isostatic pressure molding, by high-temperature vacuum sintering. The pore size and distribution of metal powder can be adjusted by selecting particle size and process parameters. According to the characteristics of pore structure, material composition, and compressive strength of different filtration materials, filtration products that are finally suitable for users are developed.

Sintered metal powder filter precision filtration, which can realize the micron grade can be a solid impurity in the separation of liquid, gas when the fluid passes through a certain accuracy of filter, the impurity is blocked in the surface of the filter cake formation, pure fluid through the filter, the contaminated or clean fluid containing impurities to the normal production of the required state, to ensure the purity of the product or of the downstream device protection equipment to work normally.

Different from the non-metallic sintered filter element, when the filter cake on the surface of the sintered metal powder filter element reaches a certain thickness, the filter element can be cleaned by backwashing or backflowing under certain reverse pressure due to its high strength.

Nickel sintered porous material is made of spherical pure nickel powder by pressing molding and sintering.

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

  • 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 the water industry are mainly rinsed with a 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.

  • Stainless steel sintered porous material allows for the use of the environment:Nitric acid, sulfuric acid, acetic acid, oxalic acid, phosphoric acid, 5% hydrochloric acid, molten sodium, liquid hydrogen, liquid nitrogen, hydrogen sulfide, acetylene, hydrogen, carbon dioxide gas, water vapor, etc.
  • Precautions for the use of stainless steel sintered porous materials:

During installation, disassembly and clean avoid scratches, collisions, and falls on hard objects. When using, the filtrate is filtered from the outside in to avoid the reverse direction. Avoid instant pressurization when the filter element works. When the filtration efficiency is less than 50%, the filter element should be cleaned in time. When cleaning the filter element, the first backflow with pure gas, backflow pressure is 1.5 times the working pressure, each time for 3-5 seconds, and 4-6 times, then backwash with clean liquid for 3-5 minutes, repeat 2-3 times. If the filter element is not good after online back blowing and backwashing, it should be removed and cleaned in time.

  • Application of stainless steel sintered porous 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.

The 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. The food and beverage industry finished product clarification filtration. Filtration and recovery of precious metal catalysts 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.
