Description

Stainless Steel Porous Sintered Metal Filter cartridges For Activated Carbon Removal

I. Manufacturing Technique
 
Stainless steel metal powder sintered porous material is made of metal or alloy powder by forming and sintering at high temperature and with a rigid structure.
 
Production Steps: Filtrate*- Isostatic compaction*-Vacuum sintering
 
Feature: the material contains a large number of connected or semi-connected pores, the pore structure is composed of regular and irregular powder particles, the size and distribution of pores and the size of porosity can be adjusted according to the powder particle size combination and preparation process to meet the actual needs of customers.
 
Advantage: good permeability, pore size, and porosity are controllable, shape stability, high filtration accuracy, wear-proof, good mechanical properties, good thermal conductivity, heat resistance, heat dissipation performance, backflush, and reuse.
 
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.
 
II. Properties of sintered porous stainless steel materials:

• High-temperature resistance, in normal use under **0 ℃.
• 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.

• 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 the precious metal catalyst in the 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.

• The decarbonization filter elements in the pharmaceutical and chemical industries are mainly back blown and backwash, 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 (**5% sodium hydroxide) and then washed with ultrasonic cleaning.
