I. Manufacturing Technique
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: sintered porous materials have excellent corrosion resistance, wear resistance, high temperature and low-temperature mechanical strength, good thermal expansion, conductivity, and magnetic conductivity.
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 Porous bubbles diffuser or sparger:
The Stainless Steel Sintered Filter can also be used as a Sparger or Diffuser. These Stainless Steel Diffusers are often used for porous gas injecting. They have a 20 or 10-micron pore size allowing small bubbles to flow through it. They can be used for gas transfer aeration, generating high volumes of fine, uniform bubbles often used for the treatment of wastewater, volatile air stripping and steam injection. With greater gas/liquid contact area, the time and volume required to dissolve gas into a liquid are reduced. This is accomplished by reducing the bubble size, which creates many tiny, slow-moving bubbles that result in a large increase in absorption.
