Product Core Characteristics
* Optical Properties: Exhibits extremely high whiteness and brightness, has strong light scattering ability, excellent covering power, and can effectively cover the underlying color.
* Dispersion: Exhibits good dispersion in water or various organic solvents and polymer systems, is easy to be uniformly mixed, and shortens the processing time.
* Stability: Possesses excellent weather resistance, anti-frosting ability, and heat resistance, can maintain color and performance stability for a long time. Some models, after organic surface treatment, can also effectively counteract the yellowing of the polymer substrate.
* Physical Indicators: Key performance parameters typically include titanium dioxide content (generally ≥ 93%), oil absorption capacity, pH value of water suspension, sieve residue, resistivity, and color removal force. Specific values vary depending on the model and application.
Main application fields
* Paint industry: It is the largest application field for titanium dioxide, especially the rutile type product is widely used in indoor and outdoor paints, industrial paints, powder paints, ship paints, etc., providing durable protection and decorative effects.
* Plastics and color masterbatches: It is used for coloring, whitening and improving covering power of plastics such as polypropylene (PP), polyethylene (PE), PVC, ABS, PS, etc., and is a key raw material for manufacturing color masterbatches.
* Paper industry: As a filler and coating pigment for paper, it improves the whiteness, opacity and printing performance of paper.
* Other industries: It is also widely used in printing inks, rubber products, cosmetics, chemical fibers, leather color pastes and ceramic glazes, etc.
Production process and packaging storage
The main production processes include the sulfuric acid method and the chlorination method. The sulfuric acid method is mature and can produce two crystal forms; the chlorination method has a continuous process and the product quality is usually better. The products are mostly packaged in 25-kilogram bags or 500/1000-kilogram bulk bags. During storage, it should be placed in a ventilated and dry place, protected from moisture, sunlight, and pressure, and avoided contact with reactive substances.
