Sintered porous titanium electrode plate for water electrolysis

Vacuum packaging in carton or wooden case

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. Properties of titanium sintered porous materials:

• Pore diameter uniformity, pore stability, high separation efficiency.

• High porosity, low filtration resistance and high permeability.

• Good chemical stability, acid and alkali corrosion resistance, oxidation resistance.

• Morphological stability, no particle shedding, comply with food hygiene and pharmaceutical GMP requirements.

• Good mechanical properties, low differential pressure, large flow.

• Strong anti-microbial ability, does not interact with microorganisms.

• Online regeneration, easy cleaning, long service life.

• Excellent biocompatibility, can be widely used in biological, food, pharmaceutical, medical industry.

• Excellent electromagnetic shielding performance.

• Good damping and shock resistance.

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.

• Decarburization filtration of pharmaceutical liquids.

• Electrolytic gas industry precision filtration, gas distribution.

• The medical industry makes biological implants.

• Water treatment industry odor sterilization filtration and ozone aeration.

• Clarification and filtration in food and beverage processing.

• Prefiltration of reverse osmosis system for electronics industry.

• Terminal filtration of petroleum products in the petrochemical industry and filtration of carbonic alkali liquid in the chemical industry.

• High pressure air filtration in aerospace industry.

• Filtration and recovery of precious metal catalyst in fine chemical industry.

• The electrode matrix of a fuel cell.

• Catalyst carrier in gas and liquid catalytic reactions.

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.

7. Method for cleaning titanium sintered porous materials:

• The decarbonization filter elements in the pharmaceutical and chemical industries are mainly backblown and backwashed, and the ultrasonic cleaning is the best.

• The filter elements of water industry are mainly rinsed with 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.
