Because of its reflective qualities, rutile titanium dioxide is a critical component in anti-corrosion coatings for industrial equipment that improves the performance of reflective anti-corrosion coatings.
The factory systems must achieve the necessary operating conditions to maintain production levels for the smooth operation of rutile titanium dioxide factories. During the production process, titanium-rich ores are processed into titanium dioxide using sulfate or chloride methods. Different acid concentrations and reaction temperatures are needed for the sulfate method, which requires dilution and proper acid storage. The chloride method survives by managing the flow of chlorine and titanium ores to produce titanium tetrachloride, which must be constantly refined into titanium dioxide.
For large-scale factories, integration with materials handling systems is required to obtain the ores. This is often achieved through conveyor systems and hoppers. Once the ores are mined, they are transported to the factory through the conveyor system. The materials are then fed into hoppers, which serve as storage containers before the ores are processed further. To prevent contamination and guarantee a high-quality product, titanium dioxide factories, especially those producing rutile titanium dioxide, require stringent controls on raw material handling.
