Powder Sintered Porous Titanium Metal Electrode Plate For Water Electrolysis

I. Manufacturing Technique

Titanium 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.

Titanium sintered porous materials are allowed to use in the environment:3% hydrochloric acid, 5% sulfuric acid, various concentrations of nitric acid (smoke nitric acid prohibited), chloroazotic acid, seawater, sodium hydroxide, carbonate and chloride salts of the aqueous solution.

II. Properties of sintered porous titanium materials:

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

V. Method for cleaning titanium sintered porous materials:

1. The decarbonization filter elements in the pharmaceutical and chemical industries are mainly back blown and back-washed, and the ultrasonic cleaning is the best.
2. The filter elements of the water industry are mainly rinsed with a 5% concentration of nitric acid.
3. 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.

VI. Why Choose Sintered Metals?

Filtration systems using sintered metal media for gaseous, solid and liquid separation have proven to be an effective and efficient alternative to other separation methods that can be vulnerable to pressure peaks, high temperatures and/or corrosive environments. Sintered metal is highly efficient in removing particulates, delivers reliable performance, is easy to clean, and has a long life in comparison with leaf filters, filter bags and plate, and frame filters.
