Detailed Product Description: | Statistical analysis of secondary particle size of nanomaterials particle system, according to the principle of division of the more advanced three typical methods are: high-speed centrifugal sedimentation method, laser particle size analysis and particle size analysis of ultrasonic power. Laser particle size analysis focused their analysis of different particle size ranges, it is divided into light diffraction and dynamic light scattering. Diffraction mainly for micron, submicron particles; scattering law aimed at nanometer particle size analysis of submicron particles. Electric ultrasonic particle size analysis method analysis is the latest in a contact angle measurement, particle size analysis of high concentrations of the main system. Particle size analysis of nanomaterials is characterized by analytical methods more contact angle measurement wholesale, mainly high concentrations of particle size analysis of the system. Particle size analysis of the characteristics of nanomaterials are more analytical methods to obtain the equivalent diameter, horizontal comparison is not between each other. Each analysis methods are applicable to a certain range, and sample conditions, should choose the appropriate analysis method based on the actual situation. Interfacial tension meter according to the principle can be divided into two kinds: Platinum Circle law and platinum plate method. Platinum Circle method is a traditional test methods, from discovery to the present time about 70 years or so. It is made of platinum wire perimeter of a certain ring. By testing the first two Platinum Circle immersed not mixed liquid interface (or liquid) 2-3mm contact angle measurement instrument manufacturers, and then slowly lift up Platinum Circle, ring and liquid will form a film. Film on Platinum Circle will have a pull down force on the entire process of measuring mention Platinum Circle film role in the ring for the most vigorous price value of the contact angle measurement, and then converted into a real interface (surface) tension. History platinum plate method applied to 20 years in a foreign country is not, even late into the country. Based on the surface of the platinum plate method / interfacial tension meter technically demanding, difficult to manufacture, domestic users really are still widely used in recent years as domestic automatic surface platinum plate method / interfacial tension meter successfully developed and put into the market. Platinum plate method is 24mm × 10mm × 0.1mm platinum plate, sandblasting the surface roughening treatment, in order to better wetting with the liquid to be measured. When testing the platinum plate lightly touch the screen (or surface), due to the effect of surface tension of liquid platinum plate will be pulled down, when the reverse surface tension of the liquid force and other forces associated with the instrument test the reach equilibrium test value is steady, if it is distilled water, ethanol and other pure substances, the entire testing process only a few seconds the fastest. Contact angle measurement brands, contact angle measurement, ShengDing instruments provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) strong, credible, in Dongguan, Guangdong specialized instrumentation industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead ShengDing instrument and you hand into the brilliant, for a better future! |
