Gradually increase the proportion of our import and export of modified titanium dioxide

In the import and export of titanium pigment products in our country,gradually increase the proportion of modified titanium dioxide.

In February 2012,the general administration of quality supervision,inspection and quarantine and the general administration of customs will titanium dioxide into strong check goods.But at present our country's existing in titanium white tests standard GB/T1706-2006 titanium white pigment,only the conventional detection project of titanium dioxide,detection,the performance characterization of modified titanium pigment identification rules.

Topic in the synthesis of the three most common modified titanium dioxide were studied,respectively is organic surface modification of titanium dioxide,ion doping titanium dioxide,titanium dioxide,biomass carbon load selection of ion doping titanium dioxide respectively doped with iron and zinc, and each doping titanium dioxide with 0.5%,0.5% and 0.5% respectively in three different concentrations,biomass carbon load titanium dioxide also select 1%,5%,10% and 5% respectively for four kind of concentration,and with four ways X-ray diffraction technique (XRD),scanning electron microscopy (SEM) analysis,electronic energy spectrum (EDS),infrared spectra (FTIR) internal structure and surface properties of titanium pigment system is analyzed,and further study of different ions,the influence of different doping amount and load ratio,to determine the different modification technology of nanoscale titanium dioxide and did not change the structure of the product differentiation.The whole subject experiment conducted a total of hundreds of times.

In order to improve the added value of modified titanium dioxide,in soil,Chinese academy of sciences,nanjing,with the help of conquering the ion doping and biomass carbon how load on the degradation of pesticide pollution impact propylene ammonia oxazine ring this problem,and studied the different modification technology of titanium dioxide in purify environment and improve the application of the coating performance.

Established in the research project of the characterization methods of titanium dioxide modified mainly including X-ray diffraction (XRD) technology (XRD),scanning electron microscopy (SEM) analysis,electronic energy spectrum (EDS),infrared spectra (FTIR),four kinds of test means,for each test method in different modification technology and application are analyzed,and the characterization of the factories and enterprises in the identification of modified titanium pigment has strong theoretical guidance and practical significance.
