In recent years, with the rapid development of the coating industry, people have higher and higher requirements for the performance of titanium dioxide, not only requiring titanium dioxide to have very good dispersibility, but also requiring titanium dioxide to have very good covering performance. The impurity content also has very high requirements. Under such high requirements, titanium dioxide with a wide range of uses has continuously improved its production technology, its performance has been continuously improved, and its application direction has continued to expand.
Among them, pigment-grade titanium dioxide has high refractive index and strong achromatic power, and has very prominent advantages in covering power and dispersibility. In addition, the chemical and physical properties of pigment-grade titanium dioxide are quite stable, and it also has very outstanding optical and electrical properties. Because of the excellent properties of pigment-grade titanium dioxide, pigment-grade titanium dioxide has been widely used in coatings and papermaking. Pigment-grade titanium dioxide has the largest proportion of applications in coatings, among which rutile titanium dioxide is widely used in industry.
Application of Pigment Grade Titanium Dioxide in Coatings
4.1 As decorative paint pigment grade
The pigment performance of titanium dioxide is very good, and most modern people also choose white or light-colored houses to decorate houses, so pigment-grade titanium dioxide is widely welcomed in house decoration. Not only that, pigment-grade titanium dioxide is also widely used in exterior coatings for ships, automobiles, etc.
4.2 As architectural coatings
Pigment-grade titanium dioxide plays a very important role in the production process of coatings, and titanium dioxide is mainly used in architectural coatings.
4.3 Making pure white paint
Most of the white paints on the market use a large amount of pigment-grade titanium dioxide in the manufacturing process.
4.4 Making colorful pattern paint
Nowadays, many pattern coatings in the market are inseparable from pigment-grade titanium dioxide in terms of color ratio and pattern. Therefore, pigment-grade titanium dioxide plays a very important role in the production of colorful pattern coatings. Pigment-grade titanium dioxide has also been widely used in automotive exterior paint, because pigment-grade titanium dioxide has very good color and luster, and the brightness is also very high.
4.5 Making special functional coatings
Pigment grade titanium dioxide is used in the production process of many high temperature resistant coatings, and high temperature resistant coatings are a kind of special functional coatings. Therefore, pigment grade titanium dioxide is an indispensable raw material in the production of special functional coatings.
4.6 Making conductive materials to conduct electricity
Titanium dioxide can also be used to make conductive materials. Since the particle surface of pigment-grade titanium dioxide can form a coating, titanium dioxide can also be used in the production of anti-static materials.
4.7 Made of cored titanium dioxide pigment grade
Titanium dioxide can also be used to make core-coated titanium dioxide, which is also often used in the production of coatings.
4.8 Slurry titanium dioxide
In the classification of titanium dioxide, there is also a slurry titanium dioxide, which does not require very complicated procedures in the production process, nor does it require a very high production cost. Therefore, slurry titanium dioxide is very popular in people's production and life. Pigment-grade titanium dioxide is indispensable in the production process of slurry titanium dioxide, so pigment-grade titanium dioxide plays a very important role in the process of making slurry titanium dioxide.
Properties and Related Effects of Nanoscale Titanium Dioxide
5.1 Utilize nano-scale titanium dioxide with the function of ultraviolet shielding
Nano-scale titanium dioxide is widely used in the production of anti-ultraviolet coatings. In many places in people's lives, it is necessary to avoid ultraviolet radiation. Therefore, it is very necessary to use nano-scale titanium dioxide with the function of ultraviolet shielding to make anti-ultraviolet coatings. The surface of the sunshade fabric needs to use nano-scale titanium dioxide, because the surface of the sunshade fabric needs to be coated with a layer of anti-ultraviolet paint, which can better prevent the direct exposure of ultraviolet rays to people's bodies. More importantly, nano-scale titanium dioxide is a non-toxic pigment, so it is more widely used in people's production and life.
5.2 Absorb UV rays
Nano-scale titanium dioxide can not only shield ultraviolet rays, but also absorb ultraviolet rays to a certain extent, so many light-colored coatings use nano-scale titanium dioxide in the production process. Weatherability of the wall.
5.3 The role of effect pigments
Rutile-type nano-scale titanium dioxide is widely used in the exterior paint of automobiles. It can not only effectively cover the bad luster of the exterior surface of automobiles, but also present a more exquisite light effect to people. In addition, the application of rutile-type nano-scale titanium dioxide on the car's topcoat allows people to see different light effects from different angles, thereby meeting people's visual needs. Rutile-type nano-scale titanium dioxide is very popular in the automotive coating industry. Many luxury cars will choose coatings containing rutile-type nano-scale titanium dioxide in the choice of exterior paint. This coating can not only produce colorful light effects, but also improve automotive Weatherability of the topcoat.
Titanium dioxide has been widely used in coating production. Therefore, our country must continuously improve production technology and produce more titanium dioxide that meets people's production and living needs. Although it is technically difficult to produce better titanium dioxide, in order to be more In order to meet the demand for titanium dioxide in coating production, relevant manufacturers need to overcome all difficulties and let titanium dioxide play a greater role in coating applications.
At present, the scale of titanium dioxide production enterprises in my country is not large enough compared with foreign titanium dioxide enterprises, and the quality of titanium dioxide has a certain gap with the international advanced level. Good service for paint making.

Different coatings have different decorative and protective effects on the surface of objects. No matter which kind of coatings have very high requirements on the covering power of pigments, it can be said that the covering power of pigments determines the covering power of paints. Whether in the construction industry or in the automotive industry, the requirements for the covering power of coatings are very high. Coatings with good covering power can not only cover up the original bad colors of objects, but also add fresher colors to objects to achieve better coverage. decorative effect. In addition, because titanium dioxide can be well combined with the fixing agent, it is widely used in the production of coatings, which can not only effectively improve various properties of coatings, but also improve the hiding power of coatings.
