Titanium dioxide (TiO₂) is a common inorganic chemical substance, the main component of which is titanium dioxide. As a high-quality white pigment, titanium dioxide has become a key raw material in many industries, due to its excellent hiding power, stability, environmental protection, and non-toxicity. In this article, we are going to talk about application and storage of titanium dioxide.
Main application of Titanium dioxide
(1) Coatings industry
Titanium dioxide can act as a pigment in coatings industry. This is the main application of titanium dioxide. Due to properties of strong hiding power, bright whiteness and weather resistance, titanium dioxide has a wide application in interior and exterior wall coatings, automotive coatings, industrial coatings, etc. It can reflect UV rays, to slow down the fading or peeling of coatings.
(2) Plastics industry
In plastics industry, titanium dioxide is used as a whitening agent and filler. It can enhance weather resistance and UV resistance of plastics, and give plastic products excellent glossiness and whiteness. It is particularly suitable for being used in polyvinyl chloride (PVC) pipes, plastic packaging, and home appliance housing. At the same time, as a filler, titanium dioxide can improve the strength of plastics.
(3) Inks industry
Titanium dioxide is often used as a white pigment and an ingredient to enhance hiding power in inks. Especially in printing industry, titanium dioxide can improve ink color and adhesion, as well as increase clarity and saturation of printing products.
(4) Paper-making industry
As an important filler in fabrication du papier industry, titanium dioxide can significantly improve the whiteness, glossiness and strength of paper. It is suitable for the production of high-grade paper and thin paper.
In addition, titanium dioxide can also be used in cosmetics to enhance concealing power and improve the color of cosmetics. At the same time, titanium dioxide can act as a food additive for candies, cakes, etc.
Storage of titanium dioxide
Although titanium dioxide has high chemical stability, some conditions still need to be paid attention to during storage to ensure its quality and performance.
– Keep dry
A humid environment can cause titanium dioxide to clump or absorb moisture, affecting dispersion and application effect. So, keep the environment ventilated and dry is necessary.
– Suitable temperature
Titanium dioxide should be stored at room temperature, avoiding extreme conditions of high or low temperatures. Usually, the storage temperature should be kept between 10°C and 30°C.
– Sealed packaging
Sealed packaging can avoid moisture or contamination. Especially when purchasing in bulk, ensure that titanium dioxide is stored in sealed bags or barrels.
Résumé
As an important inorganic pigment, market demand of titanium dioxide continues to grow, and application areas continue to expand. In the future, with the advancement of technology, titanium dioxide will have a broader development prospect.
In practical applications, titanium dioxide usually needs to be modified to improve its performance and application effect. This is because raw titanium dioxide is with uneven particle size distribution, insufficient glossiness and is easy to agglomerate. While, modified titanium dioxide exhibits better dispersibility, glossiness, weather resistance, etc, which can meet market needs.
