Description
技术领域technical field
本发明涉及一种粒度仪测试塑料专用钛白粉粒度的方法，特别是一种涉及冶金化工领域的粒度仪测试塑料专用钛白粉粒度的方法。The invention relates to a method for testing the particle size of titanium dioxide special for plastics by a particle size meter, in particular to a method for testing the particle size of titanium dioxide special for plastics by a particle size meter in the field of metallurgy and chemical industry.
背景技术Background technique
钛白粉的颜料性能影响因素较多，其中粒径大小及分布是很重要的影响因素之一。钛白粉颗粒的粒度大小，严重影响其散射系数。当其粒径为200nm时，散射系数最高，这时颜料的消色力和遮盖率最优，白度和光泽度最好，但粒径变小时，耐候性就相应下降。颜料性能优良的钛白粉，其颗粒的粒度分布宽度应尽可能的窄。因此准确检测钛白粉的粒度分布，从分布图中能够初步判断中间产品和成品质量的优劣，有利于指导钛白生产。但是现有技术的测试方法中钛白粉分散难，所测得的结果与真实结果差别较大，不能真实反映中间产品和成品质量的优劣，不利于指导钛白粉的生产加工。There are many factors affecting the pigment performance of titanium dioxide, among which particle size and distribution are one of the most important influencing factors. The particle size of titanium dioxide particles seriously affects its scattering coefficient. When the particle size is 200nm, the scattering coefficient is the highest. At this time, the pigment's decolorization power and hiding rate are the best, and the whiteness and gloss are the best. However, when the particle size becomes smaller, the weather resistance will decrease accordingly. For titanium dioxide with excellent pigment performance, the particle size distribution width of its particles should be as narrow as possible. Therefore, accurate detection of the particle size distribution of titanium dioxide can preliminarily judge the quality of intermediate products and finished products from the distribution diagram, which is conducive to guiding the production of titanium dioxide. However, titanium dioxide is difficult to disperse in the test methods of the prior art, and the measured results are quite different from the real results, which cannot truly reflect the quality of intermediate products and finished products, and are not conducive to guiding the production and processing of titanium dioxide.
