Filled a gap in identification of modified titanium dioxide

Jiangsu Inspection and Quarantine industrial centers undertake research projects "modified titanium dioxide and functional characterization of applied research" through the identification.The subject using X-ray diffraction techniques (XRD),scanning electron microscopy (SEM),electron spectroscopy test (EDS),infrared spectroscopy (FTIR) analysis method was established to identify three common-modified titanium dioxide technology.

Titanium dioxide is a big country of export.But with the social and economic development,in order to solve the production of titanium dioxide shortage of resources,reduce environmental pollution,improve resource utilization of titanium dioxide problem,the traditional single-modified titanium dioxide has gradually been replaced.How the composition and structure of the modified titanium dioxide were characterized confirm quality control department has become an urgent need to solve a real problem.

The fast development of the difficulty of identifying.

Titanium dioxide industry's development began in the 1950s,since 1998,by the construction,coatings,plastics,paper and other downstream industries,driven, showing rapid development momentum,and become the world's largest titanium producer and consumer countries.In 2011,China's titanium dioxide production capacity has exceeded 200 million tons,is expected to "second five" end,the National titanium dioxide production capacity to 500 million tons.

Import and export a large amount of titanium dioxide.In 2010,China's imports of 269,037 tons of titanium dioxide,and the export volume of 266,380 tons,in 2011 China's import volume of 22,860 tons of titanium dioxide,in 2011 exported a total of 398,131 tons of titanium dioxide.

Import and export of titanium dioxide in our products,modified gradually increase the proportion of titanium dioxide.National titanium dioxide production to large-scale national key enterprises-Titanium Co., Ltd.,Jiangsu town for example,the export of mineral processing company in 2011,and some modification of titanium dioxide modified organic processed more than 20,000 tons,accounting for 68% of the total output,Nanjing Titanium Dioxide Chemical Co., Ltd.production of modified titanium dioxide accounts for over 80% of total output.

February 2012,the State Administration of Quality Supervision and Administration of Customs will check the strength of titanium dioxide into commodities ranks.At present,China's existing standards for the testing of titanium dioxide GB/T 1706-2006 "titanium dioxide pigments", only the titanium dioxide project was carried out routine testing requirements for the characterization of modified titanium dioxide Identification of regulations vacancies.

Concentrated on studying the successful development.

The subject of the researchers themselves three most common synthetic modification of titanium dioxide studies,namely organic surface modification of titanium dioxide,doped titanium dioxide,biomass and carbon dioxide load,wherein the ion-doped titanium dioxide were selected doped with iron and zinc,respectively, and each titanium dioxide doped with 0.5%,5% and 30% in three different concentrations,biomass carbon dioxide were also selected load 1%,5%,10%,20% Fourth concentrations and were used in four ways X-ray diffraction techniques (XRD),scanning electron microscopy (SEM),electron spectroscopy (EDS),infrared spectroscopy (FTIR) on the internal structure and surface properties of titanium dioxide a systematic analysis and in-depth study of different ions with different doping effects and the load ratio to determine the different modification of nano-grade titanium dioxide products with unmodified structural differences.The whole issue has been a total of hundreds of experiments.

In order to improve the added value of the modified titanium dioxide,the subject of the Nanjing Institute of soils with the help of the capture of carbon ion doping and biomass load how to Pollutants Degradation of pesticide cyromazine impact this problem,but research different modification of titanium dioxide in a clean environment and improving coating performance application.

In the present work aimed at the long-term.

The research project was created modified titanium dioxide characterization methods include X-ray diffraction (XRD) (XRD),scanning electron microscopy (SEM), electron spectroscopy (EDS),infrared spectroscopy (FTIR) four kind of testing means,and means for each test in a different characterization of the modified technology to analyze the application of factories and enterprises in the identification of modified titanium dioxide has strong theoretical guidance and practical significance in Jiangsu section titanium dioxide production enterprises carried out to promote the application;Titanium Co., Ltd.,Jiangsu town had been intended to introduce the relevant identification techniques for the modification of titanium dioxide production process quality control,which will greatly enhance the accuracy and reliability of corporate quality control.

Import and export of titanium dioxide present in the majority of modified titanium dioxide,titanium dioxide prices are often higher than the modified unmodified titanium dioxide,and this identification technology to create an enabling determination of modified titanium dioxide,to eliminate the phenomenon of real ones and so on.

Modification of the subject in the study of titanium dioxide in coatings, degradation of organic pollutants in the application of titanium dioxide to help enterprises to upgrade and increase the added value of titanium dioxide,titanium dioxide expansion applications,with a strong application guidance,has certain social and economic benefits.
