Dirty clothes - grease, surface tension of his large, insoluble in water, detergent enable him to reduce the surface tension, which is soluble in water contact angle measurement instrument wholesale, so as to water to wash the dirt from the clothes out. Because of surfactants in detergents with. Surfactants reduce the surface tension of water, why do we add detergent in ordinary water can blow bubbles? Because the surface-active agent reduces the surface tension of water, the water is easy to blistering. Detergent molecule is very interesting, one end is hydrophilic group, can be dissolved in water, the other side is a lipophilic group, can be dissolved in oil. When the laundry when the contact angle measuring instrument where good, if there is oil, detergent on the clothes lipophilic group will work with oil "huddled" hydrophilic groups on the outside. Such hydrophilic group and the water is very close, it is easy to lipophilic groups and oil conjugate away. Plus a lot of foam, decontamination ability. Now there are a lot of detergent additives to remove other stains. Surface tension seems to us humans nothing very useful, however, pond insects but they can run around in the water, because water has a surface tension. The famous Tiger Spring Floating coins, but also because a large surface tension. The so-called contact angle measurement touch angle refers drops on a solid horizontal plane of a droplet on a solid surface solid - liquid - gas three-phase bordering point, the gas - liquid interface and solid - liquid interface of two tangents to the liquid phase sandwiched therebetween when the angle formed. The primary contact angle measuring instrument used to measure the solid angle of the liquid to the touch, that liquid wettability of solid contact angle measuring instrument can measure a variety of liquid on a variety of materials touch angle. Touch angle measurement for oil, printing and dyeing, pharmaceutical, coating, dressing and other professional research and production has a very important effect. Measure the contact angle measurement principle: when a droplet freely in space is not affected by the force field, because of the presence of interfacial tension and cylindrical ball. However, when droplets with a solid planar touch, which ultimately depends on the relative size of the shape of the adhesion of droplets of internal cohesion between the solid and liquid droplets. When a droplet placed on a solid plane, the droplets can automatically start to shop at a high temperature solid surface contact angle measurement instrument, or to the solid surface into a touch-angle droplets must exist. Buried put heating pipe, preferably with the same medium, the inner tube filled with magnesium oxide powder, in order to reduce the heat load on the heating tube surface contact angle measurement, this method can reduce the surface oxidation of the tube, effectively extending the life of the tube. Conditional, mounting holes are the best heating pipes poured into the magnesium oxide powder. Insulation measures to strengthen the mold can reduce the heat loss of the mold, the mold will reach a predetermined temperature in a shorter production time and reduce energy waste. Each engineering and technical personnel of the issue has a unique solution, I only talk about my experience.
