1/2/5/10/20/30 Micron Porosity Sintered Porous Filter Elements, Sintered Porous Titanium Filters

I. Manufacturing Technique

Sintered metal filter elements are 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.

II. Properties of sintered metal porous filter materials:

• High-temperature resistance, in normal use 300 ℃.
• 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

VI. Method for cleaning titanium sintered porous materials:

• The decarbonization filter elements in the pharmaceutical and chemical industries are mainly back blown and back-washed, 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.
