Titanium is an inert metal, has good corrosion resistance, titanium metal as raw material of titanium stick filter, filters can be implemented in alkali, strong acid medium. Can be widely used in chemical industry, pharmaceutical industry and organic solvent in the production process of filtering, the use of organic solvents such as acetone, ethanol, methyl ethyl ketone: so, if the polymer filter such as: PE, PP filter to filter, vulnerable to these organic solvents dissolved, and titanium rods in organic solvent media a stable, widely used.
Titanium filtration equipment corrosion resistance (below)
Class A: completely resistant to corrosion, corrosion rate in 0.127mm/ years.
Class B: comparison of corrosion, corrosion rate can be used as in 0.127mm~1.27mm/ years.
Class C: corrosion resistance, corrosion rate in 1.27mm/ years to cannot use.
2, high temperature resistant:
Titanium filter high temperature can reach 300 ℃, this is unmatched by other filter. This feature is widely used in high temperature environment, and the polymer material filter, its temperature difference degree, generally not more than 50 ℃, more than 50 ℃ its support and membrane will change, large deviation of filtering precision, even the PTFE filter at 120 ℃, pressure 0.2MPa in the working environment of long-term work there will be deformation, aging phenomenon. Titanium stick filter completely and can be used long-term in this environment, the micropore and the outlook does not have any change.
Widely used in: high temperature liquid filtration
Steam filter (steam filter in the process of fermentation)
3. Mechanical properties super (high strength)
Titanium stick filter with mechanical properties of super, external pressure of 20 kg, 10 kg of internal pressure damage (no joint experiment) therefore titanium rod can be applied to the process of high pressure, fast filter in. Other polymer filter pressure more than 0.5MPa in the outside, the pore size can change, even breakdown.
Application: chemical fiber manufacturing pharmaceutical industrial compressed air filtration depth underwater gas distributing coagulant cloth gas bubble.
Good mechanical properties (see chart), rugged, lightweight (the proportion is 4.51 g / cm3)
4. better regeneration effect
Titanium filter has good regeneration effect, depending on its excellent corrosion resistance, high temperature resistant performance and high strength properties, its regeneration method has physical recycling method and chemical regeneration method two:
neration method:
(1) water recoil (2) steam purge (3) the ultrasonic cleaning
Chemical treatment method:
(1) alkali washing (2) acid
The above processing method, chemical method, ultrasonic cleaning method is best, the filter attenuation degree is low, if the normal operation or cleaning, the service life of up to 10 years, the regeneration treatment titanium stick is good, in the filter has a viscosity of the liquid has been widely used in.
