Application introduction of ZG-3906 film covering power meter

ZG-3906 paint film hiding power Tester is a new photoelectric integral reflectance meter equipment, which is developed and designed for the coating industry to implement international standards. It is mainly used to measure the hiding power of the paint film and the tinting power of the pigment, and it can also be used in other related reflectance measurements. Its characteristics are: small size, simple structure, easy to use, accurate numerical display, stable number. The following article will introduce the ZG-3906 Paint Film Hiding Power Tester in detail. The ZG-3906 paint film hiding power Tester was successfully trial-produced at the end of 1983, and was held in Lanzhou in April 1984 by the Paint Industry Research Institute of the Ministry of Chemical Industry, Wuzhou Chemical Instrument Factory, Shanghai Paint Research Institute, Guangzhou Paint Factory, The work meeting attended by Tianjin Paint Factory and Northwest Paint Factory and other units, and the performance test of the instrument was carried out. The participants agreed that the technical indicators of the instrument have reached the requirements of the reflectometer specified in the international standard 150-3906: the indicated reading is proportional to the reflected light intensity, the accuracy is within 0.3%, and the spectral sensitivity is similar to that of the corresponding CIE The product of the spectral power distribution of the light source C, the spectral sensitivity of the spectral element and the spectral transmittance of the correction filter), that is:
