Coating technology: modified titanium dioxide detection technology, which is helpful for the development of titanium dioxide industry

Core tip: China is a big importer and exporter of titanium dioxide However, with the development of social economy, in order to solve the problem of titanium resource shortage in titanium dioxide production, reduce environmental pollution and improve the utilization rate of titanium dioxide resource, the traditional single titanium dioxide has been gradually replaced by modified titanium dioxide How to characterize and confirm the composition and structure of modified titanium dioxide has become a practical problem to be solved by the quality inspection department The rapid development and difficult identification of titanium dioxide industry in China began in the 1950s Since 1998, it has been driven by the downstream industries such as construction, coating, molding paper, etc Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: China is a titanium dioxide import and export country However, with the development of social economy, in order to solve the problem of titanium resource shortage in titanium dioxide production, reduce environmental pollution and improve the utilization rate of titanium dioxide resource, the traditional single titanium dioxide has been gradually replaced by modified titanium dioxide How to characterize and confirm the composition and structure of modified titanium dioxide has become a practical problem to be solved by the quality inspection department The rapid development and difficult identification of titanium dioxide industry in China began in the 1950s Since 1998, driven by the downstream industries such as construction, coating, molding paper, etc., it has shown a rapid development momentum and become the world's largest titanium dioxide producer and consumer In 2011, the annual capacity of titanium dioxide in China has exceeded 2 million tons It is estimated that by the end of the 12th Five Year Plan, the annual capacity of titanium dioxide in China will increase to 5 million tons China's titanium dioxide import and export volume is large China imported 269037 tons of titanium dioxide in 2010, 266380 tons in 2010, 22860 tons in 2011, and 398131 tons in 2011 Among the titanium dioxide products imported and exported in China, the proportion of modified titanium dioxide gradually increased Taking Jiangsu Zhenti Chemical Co., Ltd., one of the national large titanium dioxide production backbone enterprises, as an example, in 2011, the company exported more than 20000 tons of inorganic treated modified titanium dioxide and some organic treated modified titanium dioxide, accounting for 68% of the total output, while Nanjing titanium dioxide Chemical Co., Ltd produced more than 80% of the total output Since February 2012, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) and the General Administration of Customs (gacc) have included titanium dioxide in the list of commodities subject to compulsory inspection At present, China's current standard GB / t1706-2006 titanium dioxide pigment for titanium dioxide detection only specifies the routine test items of titanium dioxide, and the provisions on performance characterization and identification test of modified titanium dioxide are vacant In this project, researchers have successfully developed three kinds of most common modified titanium dioxide, which are organic surface modified titanium dioxide, ion-doped titanium dioxide and biomass carbon loaded titanium dioxide Among them, the ion-doped titanium dioxide selects doped iron and zinc, and each of them has three different concentrations of 0.5%, 5% and 30%, and biomass carbon loaded titanium dioxide respectively Four concentrations of 1%, 5%, 10% and 20% were selected for white powder, and four methods of X-ray diffraction (XRD), scanning electron microscopy (SEM), electronic energy dispersive spectroscopy (EDS) and infrared spectroscopy (FTIR) were used to systematically analyze the internal structure and surface properties of titanium white powder, and the effects of different ions, dopants and loading ratio were studied to determine the nano particles with different modification technologies The structure difference between grade titanium dioxide and unmodified product Hundreds of experiments have been carried out in the whole project In order to improve the added value of modified titanium dioxide, with the help of Nanjing Soil Institute of Chinese Academy of Sciences, the problem of how ion doping and biomass carbon load affect the degradation of Cyclopropylamine in water was solved, and the application of titanium dioxide with different modified technologies in purification environment and improvement of coating performance was studied The characterization methods of modified titanium dioxide established in the current and long-term research project mainly include X-ray diffraction (XRD), scanning electron microscopy (SEM), electron spectroscopy (EDS), infrared spectroscopy (FTIR) The characterization application of each test method in different modified technologies is analyzed The factory and enterprise are also analyzed in the characterization application of modified titanium dioxide It has a strong theoretical guidance and practical significance on the identification of titanium dioxide, which has been popularized and applied in some titanium dioxide production enterprises in Jiangsu Province; Jiangsu Zhenti Chemical Co., Ltd has planned to introduce relevant identification technology for quality control in the production process of modified titanium dioxide, which will greatly improve the accuracy and reliability of quality control in enterprises At present, most of the imported and exported titanium dioxide is modified titanium dioxide, and the price of modified titanium dioxide is often higher than that of unmodified titanium dioxide The establishment of this identification technology is conducive to the determination of modified titanium dioxide and the elimination of the phenomenon of falsification The application of modified titanium dioxide in coatings and degradation of organic pollutants studied in this project has strong application guidance to help titanium dioxide enterprises transform and upgrade, increase the added value of titanium dioxide, and expand the application field of titanium dioxide The home of coatings with certain social and economic benefits focuses on coatings, diatom mud, paint coatings and coating technology, News and information of fire retardant coating, coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fire retardant coating,
