titanium white pigment powder
The function of titanium dioxide
Regardless of solvent-based or water-based coatings, if titanium dioxide is used, its role is not only to cover and decorate. The more important role is to improve the physical and chemical properties of the coating. It enhances the chemical stability, and even improves the hiding power, color reduction power, and corrosion resistance. , Light resistance, weather resistance. Enhance the mechanical strength and adhesion of the paint film. Prevent cracks and prevent the penetration of ultraviolet rays and moisture. This delays aging and extends the life of the paint film. At the same time, it can save materials and increase varieties.
The importance of titanium dioxide in coatings
Among the pigments, white pigments are the most widely used, and both white paints and light-colored paints are used. Therefore, in the production of paints, the amount of white pigments is much more than other pigments. The white pigments commonly used in coatings include zinc white, lithopone, titanium white and so on.
Some synthetic resin coatings have a higher degree of polymerization. If zinc white is added, it will tend to thicken due to the alkalinity of zinc white and the anti-acid effect of the free fat in the coating. If zinc white is added, the weather resistance will be poor. But the use of titanium dioxide can improve the above shortcomings.
What is paint
Coatings are viscous suspensions composed of base materials, pigments, fillers, solvents and additives. It is coated on the surface of the object to form a tough coating film, which plays a role of decoration and protection on the object.
The pigment in the paint has a certain hiding power. It can not only hide the original color of the surface of the coated object, but also impart a bright color to the coating film to achieve the effect of beauty and decoration. At the same time, the pigment is closely combined with the fixing agent, which can enhance the mechanical strength and adhesion of the coating film, prevent cracks. And can increase the thickness of the coating film, prevent the penetration of ultraviolet rays and moisture, improve the aging resistance of the coating film, and extend the service life.
Why titanium dioxide is suitable for coatings
Titanium dioxide particles are small and uniform, with high photochemical stability. In terms of hiding power, rutile titanium dioxide is 7 times that of zinc white and 5.56 times that of lithopone. Anatase is 5.57 times that of zinc white and is zinc 4.3 times of barium.
In terms of color reducing power, rutile titanium dioxide is 8.3 times that of zinc white and 6.25 times that of lithopone. Anatase type titanium dioxide is 6.4 times that of zinc white and 4.8 times that of lithopone.
In terms of use effect, 1t titanium dioxide is at least equivalent to 4t lithopone.
In terms of service life (referring to outdoor powdering resistance), the coating with titanium white as the pigment is 3 times higher than the coating with lithopone as the pigment.
Therefore, the use of titanium dioxide can greatly reduce the amount of pigments in the entire coating, and at the same time, the prepared coating has bright colors and is not easy to yellow. It has the properties of light resistance, heat resistance, abrasion resistance, weather resistance, alkali resistance, sulfur resistance, and dilute acid resistance.
It is precisely because titanium white has superior performance than zinc white and lithopone, it has become the best white pigment indispensable in paint production. The amount of titanium dioxide accounts for more than 90% of the total amount of pigments used in coatings, and more than 95% of the total amount of white pigments used in coatings. It accounts for 10% to 25% of the cost of coating raw materials.
