Titanium dioxide, renowned for its excellent covering power and whiteness, is hailed as the "king of white pigments" and is extensively used in numerous fields such as paints, plastics, paper, and inks. In the production process of titanium dioxide, every step from raw material processing to final product packaging involves precise control and stringent management, where the role of control valves is particularly prominent.
During the production of titanium dioxide, processes and reaction conditions are extremely complex. For example, in the desulfurization and bleaching processes, large amounts of waste gases and liquids are treated, often containing acidic substances that are highly corrosive to metal materials. If ordinary metal valves are used, it is difficult to ensure that they will not corrode over long-term use. However, Sun Yeh ceramic-lined control valves can easily meet this challenge. The ceramic material inside the valves not only withstands the corrosion of strong acids but also effectively protects the internal structure of the valves from damage, thus extending their service life.
In the extraction process of titanium dioxide carbonate, the use of 30% TiO2 slurry and 20% sulfuric acid is necessary. The TiO2 slurry requires the control valve to be resistant to abrasion, while sulfuric acid, being a highly corrosive liquid, demands high corrosion resistance from the control valves. Similarly, Sun Yeh ceramic-lined control valves can also meet these requirements, ensuring the safety and stability of the production process.
Moreover, in the reaction process of titanium tetrachloride with fluids, the valves face complex media components such as TiCl4 slurry, coke particles, and metal particles in suspensions. This places high demands on the control valves' sealing performance and wear resistance. Sun Yeh ceramic-lined control valves can operate normally in such environments. Their excellent sealing properties ensure that gases and liquids do not leak into the external environment during the reaction process, while their outstanding wear resistance ensures that the valves do not fail due to wear over long-term use.
In addition to the key processes mentioned above, Sun Yeh ceramic-lined control valves play an important role in other stages of titanium dioxide production. In the production of titanium dioxide by the chloride process, ceramic-lined control valves can be used in operations such as titanium dioxide slurry preparation, bag filter air, discharging, raw material discharging, feeding in chlorination furnaces, and handling high titanium slag. In the production of titanium dioxide by the sulfate process, ceramic-lined control valves can be used in operations such as gas-powder feeding, acid digestion, slurry preparation, sedimentation, crystallization, lime milk, filter press feeding, and post-treatment. In these conditions, Sun Yeh ceramic-lined control valves consistently demonstrate their excellent performance and stable operation.
Overall, Sun Yeh ceramic-lined control valves are widely applied in the titanium dioxide industry. Due to their excellent corrosion resistance and wear resistance, Sun Yeh ceramic-lined control valves help enterprises reduce maintenance costs and improve production efficiency.
