III. Manufacturing Process of Rutile Titanium Dioxide for Paint Factories

The production of high-quality rutile titanium dioxide industry grade for paint factories is a complex chemical engineering process. While both sulfate and chloride processes are used, the sulfate process is often employed for industrial grades like Pangang CR-350, especially in regions with abundant ilmenite ore. Here, we outline the key stages of the Sulfate Process:

Detailed Process Flow (Sulfate Process)

1. Raw Material Preparation (Ilmenite Ore):
   • Description: Ilmenite (FeTiO3), an iron titanium oxide mineral, is the primary raw material. It is typically crushed, ground, and then subjected to magnetic separation to concentrate the titanium content and remove impurities.
   • Key Node: Quality control of raw ore, ensuring minimal undesirable elements that could impact final product purity.
2. Acid Digestion:
   • Description: The prepared ilmenite ore reacts with concentrated sulfuric acid (H2SO4) in large agitated reactors. This exothermic reaction dissolves the titanium and iron components to form titanium sulfate (Ti(SO4)2) and iron sulfates (FeSO4, Fe2(SO4)3).
   • Key Node: Precise temperature and concentration control to ensure complete digestion and minimize side reactions.
3. Clarification and Iron Removal (Crystallization/Filtration):
   • Description: The resulting "black liquor" (solution of titanium and iron sulfates) is clarified to remove insoluble impurities. Iron is then removed, typically by cooling the solution to crystallize ferrous sulfate heptahydrate (FeSO4·7H2O), also known as "copperas." This iron by-product can be further processed or sold.
   • Key Node: Efficient separation of iron to prevent contamination of the final TiO2 pigment and achieve desired whiteness.
4. Hydrolysis:
   • Description: The purified titanium sulfate solution is carefully heated (hydrolyzed) with steam, causing the titanium to precipitate as hydrous titanium dioxide (TiO2·nH2O). This amorphous precipitate is often referred to as "titanium hydrate."
   • Key Node: Critical control of hydrolysis conditions (temperature, pH, reaction time, presence of nucleating agents) to ensure uniform particle size and crystal growth, which directly impacts the pigment's properties.
5. Washing and Filtration:
   • Description: The precipitated hydrous titanium dioxide slurry is thoroughly washed to remove residual acids and soluble salts, ensuring high purity. This is typically done through multiple washing and filtration cycles.
   • Key Node: Effective washing to reduce impurities, which are detrimental to pigment quality and can cause yellowing or chalking in paints.
6. Calcination:
   • Description: The washed titanium hydrate is then calcined (heated) in rotary kilns at high temperatures (typically 800-1000°C). This process drives off water, converts the amorphous titanium hydrate into crystalline TiO2, and promotes the transformation from the less stable anatase phase to the more desirable rutile phase.
   • Key Node: Temperature profile, retention time, and atmosphere in the kiln are meticulously controlled to achieve a high rutile content and optimize particle morphology.
7. Milling/Grinding:
   • Description: The calcined TiO2, now in coarse aggregates, is ground into a fine powder using various mills (e.g., fluid energy mills or micronizers) to break down aggregates and achieve the desired particle size distribution for optimal light scattering and dispersion in paint systems.
   • Key Node: Uniform particle size distribution is vital for opacity, tinting strength, and ease of dispersion.
8. Surface Treatment:
   • Description: This is a crucial step to enhance the pigment's performance in specific applications. The TiO2 particles are coated with inorganic oxides (e.g., alumina, silica, zirconia) and/or organic compounds. These coatings improve dispersibility, weatherability, chalking resistance, and compatibility with various binders.
   • Key Node: The type and amount of surface treatment agents are tailored to the intended application (e.g., paints, plastics), significantly influencing the pigment's performance characteristics.
9. Final Product Testing & Packaging:
   • Description: The finished product undergoes stringent quality control checks to ensure it meets specifications (as per ISO, ASTM, and internal standards). This includes tests for TiO2 content, whiteness, oil absorption, dispersibility, and tinting strength. Once approved, it is packaged for shipment.
   • Key Node: Comprehensive testing ensures consistency and reliability, critical for `high quality titanium dioxide casa 13463-67-7 tio2 powder chinese good price` offerings.

This intricate process ensures the consistent production of high-quality rutile titanium dioxide industry grade for paint factories, ready for integration into various coating formulations.

VII. Professional FAQ for Rutile Titanium Dioxide in Paints

Here are answers to common professional questions regarding rutile titanium dioxide industry grade for paint factories:

1. What is the primary difference between Rutile and Anatase TiO2 for paint applications?

   Rutile titanium dioxide industry grade for paint factories is preferred for most paint applications due to its higher refractive index (providing superior opacity and hiding power), excellent UV light absorption (leading to better weatherability and chalking resistance), and greater stability. Anatase TiO2, while whiter, is less durable for exterior use due to its tendency to promote chalking.

2. Why is surface treatment crucial for TiO2 pigment in paints?

   Surface treatment involves coating TiO2 particles with inorganic (e.g., alumina, silica, zirconia) and/or organic compounds. This process improves dispersibility in various paint binders, enhances weatherability (reduces photocatalytic activity), improves gloss retention, and prevents agglomeration, ensuring optimal performance and stability of the paint film.

3. What does "Oil Absorption" mean for TiO2 and why is it important in paints?

   Oil absorption (measured in g/100g) indicates the amount of oil required to wet 100g of pigment to form a paste. Lower oil absorption means the pigment needs less binder to disperse, resulting in higher pigment volume concentration (PVC) possible, leading to better hiding power and potentially lower formulation costs. It's a critical parameter for paint formulators.

4. How does the particle size distribution of rutile titanium dioxide industry grade for paint factories affect paint performance?

   Optimal particle size distribution (typically around 0.2-0.3 micrometers) for rutile titanium dioxide industry grade for paint factories is crucial for maximum light scattering, which directly correlates to opacity and tinting strength. Too fine or too coarse particles can reduce these properties. Uniform distribution also enhances gloss and smooth film appearance.

5. What international standards should paint manufacturers look for when sourcing TiO2?

   Paint manufacturers should look for TiO2 suppliers compliant with international standards such as ISO 591-1 (specifies grades of titanium dioxide pigments), ASTM D476 (Standard Specification for Titanium Dioxide Pigments), and ISO 9001 (Quality Management System). Compliance with REACH regulations is also important for European markets.

6. Can Pangang CR-350 be used in both solvent-based and water-based paints?
