In real life, there are many areas such as energy, materials, pharmaceuticals, chemicals, metallurgy, electronics, machinery, light industry, construction and environmental protection are all closely related with the size of molecular materials. In polymer materials such as polyethylene resin is a multi-pores of the powdered substance Dongguan contact angle measurement, its nature and performance not only by the molecular characteristics (molecular weight, molecular weight distribution, chain configuration) impact, and the morphological and molecular characteristics (such as surface morphology particles having an average particle size, particle size distribution) are closely related. Polyethylene molecules and morphology in turn determines the characteristics and properties of polymer products during molding. Studies have shown that the morphology of the resin particles is good, moderate average particle size, particle size distribution in favor of a uniform polymer forming contact angle measurement, therefore, people often need to test PVC resin particle size analysis. In terms of nano-modified plastics additives sweet, add nanomaterials as a filler in plastics plastics, not only can increase the mechanical strength of plastic, can also increase the performance of plastic sealed gas and increased fire-retardant properties. These reflect the performance of direct and shape, particle size and distribution and other factors add nanomaterials are closely related. Therefore, the need for characterization and analysis of these nano-particle additives. In terms of modern ceramics, functional ceramics composed of nanoparticles is an important research direction of the ceramic material. By using nano-functional ceramic material can significantly alter the physical and chemical properties of ceramics, such as toughness. Many important properties of ceramic powder materials by the average particle size and particle size distribution and other parameters of the decision. Coated areas, pigment particle size determines its coloring ability, additive particle size determines the film strength and wear resistance. In the field of electronic materials, the phosphor particle size determine the display brightness and definition television, monitor, etc. of the screen. In the field of catalysts, the catalyst particle size, distribution and morphology are determined in part its catalytic activity. Thus, with the development of science and technology offer contact angle measurement, particle size analysis techniques related by widespread attention, has evolved into an important measure of school branch. Germany SITA dynamic surface tension meter is all ceramic ink manufacturers specification test instruments can be used for formulation development and quality inspection. The primary use in the production process to monitor incoming products, quality and stability of the products before shipment of raw materials, detailed test plans are as follows: First, the product 1, and similar products cf. malls, such as other brands of sophisticated goods or inkjet The function of good contact angle measurement sample sales, know reorientation goods. 2, is not the same distinction between batches produced 3, the difference between the test chamber and the surface tension of the ink planning actual plant produced ink 4, the same sample, the same surfactant content, not the same as the difference between the time stored. (For example, measured once every other month) surface tension test instrument used to make the ink contact angle measurement instrument sales, ShengDing instrument (certified), contact angle measurement provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) is Dongguan, Guangdong, dedicated instrumentation leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Sheng Ding instrument in leadership with the staff warmly welcome all inquiries negotiations to create ShengDing instrument a better future.
