Porous Titanium Sintered Metal Filter Disc For PEM Electrolysers Water Electrolysis

Porous Titanium Sintered Metal Filter Disc For PEM Electrolysers Water Electrolysis

1. Manufacturing Technique
Titanium sintered porous material is a kind of porous material with high quality spherical and high purity titanium powder as raw material and it is made rigid by forming and sintering at high temperature.

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.

2. Specification of titanium sintered porous materials

3. Specification of porous titanium disc

Size:Max OD 300mm

Thickness : 0.5-2.2mm

Micro pore size: 5-100um

4. Application of titanium sintered porous materials

Titanium sintered porous materials are mostly used for filtering materials,electrodes,heat transfer materials,catalyst carrier materials,noise cancelling materials according to their physical and structural properties.

It is mainly used for filtration and purification of liquid and gas. It is widely used in petrochemical and biomedicine.It is also the material of ozone aeration technology - ozone diffusion plate.In the hydrogen energy industry, it is widely used as a porous electrode material because of its good electrical conductivity, corrosion resistance and affinity with hydrogen, which can be coated with platinum, ruthenium and iridium and other metals to enhance its electrocatalytic performance.

5. Titanium sintered porous materials are allowed to use in 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.

6. Precautions for the use of titanium 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, first backblow with pure gas, backblow pressure is 1.5 times of 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 backblowing and backwashing, it should be removed and cleaned in time.
