Dongguan droplets angle ShengDing instrument (certified), drop angle provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) is specialized in the "contact angle measurement, tensile tester, drop angle detector, surface and interface equipment, mold Monitor" of the enterprise, the company of "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. On the solid surface of the solid - liquid - gas three - phase bordering point by gas - liquid interface and the solid - liquid interface of two tangent angle of the liquid interposed therebetween is called the contact angle formed. In industrial processes, usually using contact angle measurement complete interface directly antennae precise measurements. A brief description of common measurement methods and related operational requirements below. Note that the degree of understanding of user needs with features for testing the surface tension, the surface tension of the test method JC2000 series came in the hanging drop method for Guangzhou droplets corner, classic, accurate, but the operator requires high (influenced by the operational level ). If you need a different test batch testing table interfacial tension, it is recommended to use my company's JK99 series of automatic tension meter, when the droplet freely in space without affecting the force field, due to the presence of interfacial tension and cylindrical ball. However Zhuhai droplets angle, when the liquid droplets with the solid planar contact, which depends on the final shape of the droplet internal cohesion and adhesion to the relative magnitude between the droplets and solid. When a droplet placed on a solid plane, the droplets can automatically start to shop in Shenzhen solid surface angle of water droplets, or in contact with the solid surface into a certain angle of droplets exist. ? Based particle Brownian motion? Brownian motion of the particle size measuring method based on the Brownian motion is suspended in a medium (gas or liquid) of fine particles and medium molecular interaction even constant random motion. Although no law Brownian motion looks complicated, however, scientists have revealed some deep research or statistical regularities of their Brownian motion, that under certain conditions and within a certain time, the average displacement of particles moving average has a certain values, and the average displacement is inversely proportional to the square of the particle diameter. Brownian motion of the particles based on the displacement of the center of the particle trajectory method and based on the speed of light Brownian motion stitch feasibility study has been carried out. Based on the particle size measurement method for the precise measurement of the Brownian motion of the particle size distribution of ultrafine particles has opened up new areas of technology? Based particle size measurement method Brownian motion Brownian motion is suspended in the medium (gas or liquid) of fine particles and medium molecular Even the constant interaction of random motion.
