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.

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.
