1. Overview of the Titanium Dioxide Industry
Titanium dioxide is a core inorganic chemical pigment mainly composed of titanium dioxide powder. It has a density ranging from 3.9 g/cm³ to 4.3 g/cm³, and features water insolubility, stable chemical properties, excellent weather resistance, non-toxicity and environmental friendliness.
Thanks to superior whiteness, hiding power and optical performance, titanium dioxide is widely used in coatings, plastics, papermaking, printing inks, rubber and other industrial sectors, as well as daily fields including cosmetics and food packaging. It has become an indispensable basic raw material in modern industries. The production of titanium dioxide involves complex working conditions, with pipelines conveying media containing solid particles and corrosive substances under high temperature and high pressure. This sets stringent requirements for the performance of supporting pipeline valves.
2. Core Performance Advantages of Electric Hard-seated Ball Valves
Tailored for the harsh operating conditions of titanium dioxide production featuring high temperature, high pressure, solid particles and severe abrasion, electric hard-seated ball valves stand out as the preferred valve solution for the industry with multiple superior properties:
2.1 Automated Operation with Precise Flow Control
Equipped with electric actuators, the valves support on-site opening/closing and remote automatic control, effectively cutting labor costs. The valve opening can be adjusted accurately to realize refined flow regulation, meeting the demands of continuous production lines and improving overall operational efficiency.
2.2 High Temperature & Pressure Resistance for Stable Operation
The valve body and internal components adopt reinforced design with outstanding heat and pressure resistance. They can operate stably for a long time in high-temperature and high-pressure pipeline systems, fully adapting to various high-temperature medium delivery pipelines in titanium dioxide production and eliminating potential safety risks caused by fluctuating working conditions.
2.3 High Hardness & Abrasion Resistance against Erosion
Key sealing components such as balls and seats are made of high-hardness alloy steel. The material delivers excellent wear resistance and can withstand long-term scouring and abrasion from titanium dioxide powder and solid particle media, minimizing valve failures and extending service life fundamentally.
2.4 Compact Structure with Strong Installation Adaptability
Featuring a simple and compact structure, the valves occupy limited pipeline space and allow flexible layout. They fit well with the complex pipeline arrangement in titanium dioxide plants and reduce on-site construction difficulty.
2.5 Wide Media Compatibility for Diverse Scenarios
The valves are applicable to various media including water, steam, corrosive liquids, particle-containing slurry and gas. Besides the titanium dioxide industry, they are also widely adopted in petroleum, chemical engineering, power generation, metallurgy and other fields with strong universal adaptability.
2.6 Simple Maintenance & Lower Comprehensive Costs
With high operational stability and long maintenance-free cycles, the valves require infrequent routine inspection under normal working conditions. They save time on equipment maintenance and greatly reduce the long-term operation and maintenance costs for enterprises.
3. Practical Application of Electric Hard-seated Ball Valves in Titanium Dioxide Production
At present, the mainstream production processes of titanium dioxide are the sulfate process and the chloride process. Electric hard-seated ball valves are extensively used throughout the whole production procedures of both processes.
3.1 Application in Sulfate Process Titanium Dioxide Production
- Acid Hydrolysis Process: Regulates the flow and temperature of sulfuric acid to ensure steady and uniform acid hydrolysis reactions and control the quality of upstream production.
- Settling & Fine Filtration Process: Discharges impurities and residual materials from settling tanks to guarantee material purification effect.
- Hydrolysis Process: Precisely controls hydrolysis rate and heating temperature to ensure qualified hydrolyzed products.
- Calcination Process: Adjusts gas flow and temperature under high-temperature conditions to achieve ideal calcination and forming of titanium dioxide.
3.2 Application in Chloride Process Titanium Dioxide Production
- Chlorination Process: Controls the flow and temperature of chlorine gas to maintain continuous and stable chlorination reactions.
- Oxidation Process: Regulates oxygen flow and temperature to ensure the smooth oxidation of titanium tetrachloride into titanium dioxide.
- Post-treatment Process: Accurately controls medium delivery in wet grinding, inorganic coating, drying, jet milling and other procedures to complete the fine processing of finished titanium dioxide products.
