(www.dgshengding.com) is specialized in the "contact angle measurement, tensile tester, drop angle detector, tables, interface instrument" of the enterprise, the company adhering to the "honesty, hard service" philosophy, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. In real life, the contact angle measuring instrument, 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, its properties and performance not only by the molecular characteristics (molecular weight, molecular weight distribution, chain configuration) impact, and morphological characteristics of the molecule (e.g., the particle surface morphology, 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 contact angle measuring instrument retail, particle morphology resin is good, moderate average particle size, particle size distribution uniform in favor of a polymer molding, and therefore, people often need to test PVC resin particle size analysis. Nano-modified plastics additives in the sweet side, add nanomaterials as a filler in plastics plastics, not only can increase the mechanical strength of the plastic, airtight plastic can also increase the performance of gas and increased 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 ceramic materials, functional ceramics composed of nanoparticles is an important research direction of the ceramic material. By using nano-functional ceramic material can significantly alter the function of the physical and chemical properties of ceramic original contact angle measuring instrument, 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, about the particle size analysis technology has been widespread attention, has gradually developed into a measure of an important branch of science. Beautiful lotus lightness finds, rolled down from the lotus leaf drops can remove dirt and bacteria on adsorption phenomenon scientists call "self-cleaning effect" or "lotus effect" lotus leaf . 1997 German botanist Professor William Bass Lott inspiration from the successful production of easy-to-clean surface buildings and transportation coatings. Recently, researchers at the University of Michigan through the development of theoretical models, the first successful nano hairy structure and chemical composition and microstructure separated, the essence of the principle of self-cleaning lotus effect research. When a drop of water falls on a lotus leaf, lotus leaf with water drops between the formation of a high degree of contact angle (greater than 90 degrees), so that it gathered into beads without diffusion. Typically, human skin has a slight hydrophobicity, the contact angle is about 90 degrees, and the contact angle approaches 170 degrees lotus leaf, leaf surface extremely hydrophobic. But scientists found that although few actually touching the leaves of the rain droplets fall is not without friction, water droplets away dirt and bacteria on the leaves, and act as a "self-cleaning" function. Scientists for the first time the hairy leaves of the nano-structure and micro-structure and chemical composition separated. They found that the contact angle measuring instrument wholesale, lotus leaf surface in addition to containing wax composition, the two structures, "lotus effect" and the leaves of the related, one is raised micron, a nanoscale hairy structure. The contact angle of the two structures containing lotus leaf is 142 degrees, the contact angle of the leaves containing only micro structure is 126 degrees, the contact angle of the surface of the wax alone containing only 74 degrees. Scientists believe that hairy nanoscale structure increases the contact angle of 16 degrees, the two structures are the main causes of "lotus effect". "Lotus effect" as a good model that can be used to study many areas, such as lotus effect on the production of coatings can be easy to clean the surface of the house or building, the future lotus effect will have a more broad prospects for development
