5.) Technical Performance Characteristics of Titanium Rods
A.) Corrosion Resistance
Titanium metal is an inert metal with excellent corrosion resistance. The titanium rod filter element made of titanium metal can be filtered in strong alkali and strong acid media. It can be widely used in the chemical industry. In the filtration of the organic lysozyme production process in the pharmaceutical industry, due to the application of organic solvents such as: acetone, ethanol, methyl ethyl ketone, etc., if polymer filter elements such as PE, PP filter elements are used for filtration. It is easily dissolved by these organic solvents, and titanium rods are quite stable in the medium of organic solvents and are widely used.
Corrosion resistance of titanium filter equipment
Class A: Completely resistant to corrosion, the corrosion rate is below 0.127mm/year.
Class B: Relatively corrosion-resistant, and the corrosion rate is below 0.127mm~1.27mm/year, which can be used.
Class C: It is corrosion resistant, and it cannot be used if the corrosion rate is above 1.27mm/year.
B.) High Temperature Resistance
The titanium filter element can withstand high temperatures up to 300°C, which is unmatched by other filter elements. This feature is widely used in high-temperature operating environments, and the polymer filter element has poor temperature resistance, generally not exceeding 50 ℃, and its support and filter membrane will change when it exceeds 50 ℃, and the filtration accuracy will have a large deviation, even if it is four. If the fluorine filter element is above 120℃ and the external pressure is 0.2MPa, it will be deformed and aging for a long time. The titanium rod filter element can be used in this environment for a long time without any changes in its micropores and appearance. Widely used: filtration of high-temperature liquids, steam filtration (steam filtration in fermentation processes)
C.) Super Mechanical Properties (High Strength)
Titanium rod filter element has super mechanical properties, external pressure 20kg, internal pressure destructive force 10kg (no joint test), so titanium rod can be used in the process of high pressure and rapid filtration. When the external pressure of other polymer filter elements exceeds 0.5MPa, the pore size of the micropores will change and even be broken down. Application: Compressed air filtration of chemical fiber manufacturing industry, medical industry, air distribution, foaming of coagulant in deep water, etc. Good mechanical properties, strong and light weight (specific gravity 4.51 g/cm3)
D.) Good Regeneration Effect
The titanium rod filter element has a good regeneration effect, which depends on its excellent corrosion resistance, high temperature resistance and high strength performance. Its regeneration methods include physical regeneration treatment methods and chemical regeneration methods:
Physical regeneration method:
(1) Pure water recoil
(2) Steam blowback
(3) Ultrasonic cleaning
Chemical Treatment Method of Titanium Rod Filter Element:
(1) Alkaline washing (2) Acid washing Among the above treatment methods, chemical treatment method and ultrasonic cleaning method are the best.
The degree of filtering attenuation is low, if the normal operation
