Coating knowledge: introduction to pigment and optics of titanium dioxide

The core tip: titanium dioxide (TiO2) is a very important white pigment, which is widely used in coating industry Because it can effectively scatter the visible light, so it can be incorporated into the coating to achieve whitening brightness and transparency Titanium dioxide is a commercial crystal, rutile titanium dioxide pigment is the first choice, because their scattering light is more effective, more stable and more durable than anatase pigment Titanium dioxide pigments are insoluble in automotive coatings, so they are mainly composed of particle size pigments and chemical surfaces that determine dispersion properties, properties, such as chemistry, photochemistry, and physical properties Commercial grade titanium dioxide will, in some cases Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings news: titanium dioxide (TiO2) is a very important white pigment, which is widely used in the coating industry Because it can effectively scatter the visible light, so it can be incorporated into the coating to achieve whitening brightness and transparency Titanium dioxide is a commercial crystal, rutile titanium dioxide pigment is the first choice, because their scattering light is more effective, more stable and more durable than anatase pigment Titanium dioxide pigments are insoluble in automotive coatings, so they are mainly composed of particle size pigments and chemical surfaces that determine dispersion properties, properties, such as chemistry, photochemistry, and physical properties Titanium dioxide with commercial grade can be treated with organic and inorganic surface treatment in some cases Inorganic surface modifiers are usually precipitated coating of alumina and silica, which is a good way to control the type, particle size and deposition of titanium dioxide These inorganic surface treatments in one or more series of organic liquids can improve the important performance characteristics of titanium dioxide, such as dispersion in water and hidden power efficiency, aging resistance, and color change resistance heat and / or light The dispersion can be improved by selecting the pigment system with organic surface treatment It is not appropriate to analyze the titanium dioxide content of the titanium dioxide pigment in the performance of the coating For example, the DuPont titanium dioxide grade index of 80-88% (the lowest content of TiO2) is significantly better than the high content TiO2 Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
