introduction
In recent years, with the rapid development of the coating industry, people have increasingly high requirements for the performance of
Titanium Dioxide. They not only require titanium dioxide to have very good dispersibility, but also require it to have very good covering performance. At the same time, they also have very high requirements for the impurity content of titanium dioxide. Under such high requirements, the production technology and performance of titanium dioxide, which has a wide range of applications, are constantly improving, and its application directions are also expanding.
Among them, pigment grade titanium dioxide has a high refractive index and strong color fading ability, which has outstanding advantages in both coverage and dispersibility. Therefore, pigment grade titanium dioxide has been widely used in coatings and papermaking. The application proportion of pigment grade titanium dioxide in coatings is the largest, among which rutile titanium dioxide is widely used in industry.
Different coatings have different decorative and protective effects on the surface of objects. Regardless of which type of coating has a very high requirement for the covering power of pigments, it can be said that the covering power of pigments determines the covering power of coatings. Whether in the construction industry or 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, achieving better decorative effects.
Application of pigment grade titanium dioxide in coatings
one point one
As a decorative coating
The pigment performance of pigment grade titanium dioxide is very good, and modern people mostly choose white or light colors to decorate their houses. Therefore, pigment grade titanium dioxide has been widely welcomed in house decoration. Not only that, pigment grade titanium dioxide is also widely used in external coatings for ships, cars, and other applications.
one point two
As an architectural coating
Pigment grade titanium dioxide plays a very important role in the production process of coatings, and it is mainly used in architectural coatings.
one point three
Produce pure white paint
Most white coatings on the market use a large amount of pigment grade titanium dioxide in the manufacturing process.
one point four
Produce colorful patterned coatings
Nowadays, many patterned coatings in the market cannot do without 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 patterned coatings. Pigment grade titanium dioxide has also been widely used in the exterior paint of automobiles because it has excellent color and high brightness.
one point five
Produce special functional coatings
Many high-temperature resistant coatings use pigment grade titanium dioxide in the production process, and high-temperature resistant coatings are a type of special functional coatings. Therefore, pigment grade titanium dioxide is an essential raw material in the production of special functional coatings.
one point six
Make conductive materials conductive
Titanium dioxide can also be used to make conductive materials. Due to the coating formed on the surface of pigment grade titanium dioxide particles, titanium dioxide can also be used in the production of anti-static materials.
one point seven
Made of core titanium dioxide powder
Pigment grade titanium dioxide can also be used to make nucleated titanium dioxide, which is often used in the production of coatings.
one point eight
Pulp material titanium dioxide
In the classification of titanium dioxide, there is also a type of slurry titanium dioxide, which does not require very complex processes or high production costs in the production process. Therefore, slurry titanium dioxide is very popular in people's production and life. And 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 production of slurry titanium dioxide.
Performance and related effects of 2-nanometer titanium dioxide powder
two point one
UV shielding effect
Nano scale titanium dioxide is widely used in the production process of UV resistant coatings. In many places of people's lives, it is necessary to avoid UV exposure. Therefore, it is essential to use the UV shielding function of nano scale titanium dioxide to produce UV resistant coatings.
The surface of the sunshade fabric requires the use of nano-sized titanium dioxide, because the fabric surface of the sunshade needs to be coated with a layer of UV resistant paint, which can better prevent direct exposure of UV rays to people's bodies. More importantly, nanoscale titanium dioxide is a non-toxic pigment, so its application in people's production and daily life is even more extensive.
two point two
UV absorption effect
Nanoscale titanium dioxide can not only shield against ultraviolet radiation, but also absorb it to a certain extent. Therefore, many light colored coatings use nanoscale titanium dioxide in the production process. In addition, this titanium dioxide can also improve the weather resistance of building exterior walls.
two point three
The function of effect pigments
The application of rutile type nanoscale titanium dioxide in automotive exterior coatings is very extensive. It can not only effectively cover the poor gloss of automotive exterior surfaces, but also present more exquisite light effects to people. In addition, the application of rutile nano titanium dioxide on the topcoat of automobiles can allow people to see different light effects from different angles, thus meeting their visual needs.
Rutile nano titanium dioxide is very popular in the automotive coatings industry, and many luxury cars choose coatings containing rutile nano titanium dioxide for their exterior surfaces. This coating not only produces colorful light effects, but also improves the weather resistance of automotive topcoats.
3 Conclusion
Titanium dioxide is widely used in coating production, so China must continuously improve production technology and produce more titanium dioxide that meets people's production and living needs. Although producing better titanium dioxide has certain technical difficulties, in order to better meet the demand for titanium dioxide in coating production, relevant manufacturers need to overcome all difficulties and make titanium dioxide play a greater role in coating applications.
At present, the scale of enterprises producing titanium dioxide in China is not large enough compared to foreign titanium dioxide enterprises, and the quality of titanium dioxide has a certain gap with the international advanced level. China needs to develop more advanced technology methods for producing titanium dioxide as much as possible, in order to better serve the production of coatings.
