The application of Gr2 pure titanium in the field of electrolytic cells
In fields such as hydrometallurgy, chlor-alkali industry and electrochemical water treatment, electrolytic cells are core production equipment. The corrosion resistance and service life of their materials directly affect production efficiency and cost. Industrial pure titanium, especially Gr2 grade, has become an irreplaceable ideal material for manufacturing electrolytic cells and their key internal components due to its outstanding performance.
Outstanding corrosion-resistant foundation
During the electrolysis process, equipment often needs to be "immersed" in highly corrosive chemical environments, such as solutions rich in chloride ions, strong acids or strong alkalis. This is just like throwing ordinary metals into a "chemical dye VAT", where they are very likely to be corroded and damaged rapidly.
The reason why Gr2 industrial pure titanium can become the "star material" in such environments lies in the fact that its surface can automatically form an extremely thin but exceptionally strong oxide film, just like putting on an invisible "protective armor" for the material.
It is precisely this "armor" that enables Gr2 titanium to demonstrate corrosion resistance far exceeding that of traditional materials such as stainless steel when exposed to oxidizing environments and chlorine-containing media. Especially in the chlor-alkali industry (used for the production of basic chemical raw materials such as chlorine gas and caustic soda), when it is used as a cathode, it can calmly withstand the dual erosion of wet chlorine gas and high-temperature brine, thus ensuring the long-term stable and safe operation of production facilities.
Key application parts
In electrolytic cells, Gr2 titanium is mainly applied in the following key parts:
1. Cathode plate: Due to its excellent electrical conductivity and absolute stability in a cathodic environment, it is the standard configuration for diaphragm and ion-exchange membrane electrolytic cells.
2. Anode basket/protective sleeve: In electrolytic metallurgy, it is used to hold anode materials and can withstand the corrosion of electrolyte.
3. Heating coil and internal components: Used in electrolytic cells that require heating or cooling, its corrosion resistance ensures heat transfer efficiency and structural integrity.
4. Cell lining: As the anti-corrosion lining of the electrolytic cell body, it provides comprehensive protection for the entire equipment.
The comprehensive economic benefits are remarkable
Although the initial investment cost of Gr2 titanium is higher than that of ordinary steel, the long-term economic benefits it brings are very prominent. Its extremely low corrosion rate significantly extends the equipment maintenance cycle and service life, which can last for several decades. At the same time, because its surface is not prone to scaling or contaminating the product, it can ensure the purity of the produced metals or chemicals. In addition, Gr2 titanium has excellent strength and weldability, and is convenient for processing, manufacturing and maintenance.
