Product Details

Product Description

Product Description
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.

4. 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.
5. 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.
