The excellent performance of emery wear-resistant floor

Social progress is reflected in all aspects of life, such as the floor. Now the development of the floor can be said to be an indispensable thing in our lives. For many people, it is very difficult to walk on hard ground and then walk on muddy roads. With the development of the times, the change of the floor has also experienced many periods. At present, the emery wear-resistant floor is a popular type of floor. Emery wear-resistant floor has many excellent properties, which is the reason for its wide application. Due to the excellent performance of diamond wear-resistant floor, in life to avoid the floor moisture, moisture and many other issues, its excellent flatness, flatness and smoothness can also avoid local damp floor. And if ordinary concrete, we know that the humidity of concrete is indeed the most common picture, especially in summer, when the humid air with higher temperature (relative humidity greater than 90%) meets the ground with lower temperature, smooth, and non-absorbent, The condensation of water droplets does bring great inconvenience to life. Due to its compact structure, it is not easy to be penetrated by water and gas, and naturally avoids moisture. Due to its high hardness, the service life of the emery wear-resistant floor is very long, and the problem of using twenty or thirty years is really not big.

Development Trend of Grinding Machine Industry in China

Development Trend of Grinding Machine Industry in China Development Trend of Grinding Machine Industry in China Although the development of China's grinding machine industry has made some achievements, but the existing problems in the industry can not be ignored. After the reform and opening up, China's polishing industry began to start, so the problems presented in the development of China's polishing industry are also reflected in the surface treatment industry. After years of development, China's economy has taken off, the construction of market economy has made great achievements, and the scale of polishing industry is also growing. However, looking closely at the development of the product structure of the polishing industry, the vast majority of grinding machinery manufacturing enterprises in China are concentrated in low-end products, and high-end products also need to rely on imports from abroad. The development of China's high-end polishing equipment is seriously out of touch with the development of China's machinery and equipment. "2013-2017 grinding machine industry competition pattern and investment strategy research and consultation report" shows: grinding machine in such a big environment, from the old industrial base of Xingwan gradually developed, specializing in high-end precision polishing equipment research and development and production. At present, its production of multi-station cylindrical polishing machine, single-head cylindrical polishing machine, tube polishing machine, small centerless grinder, etc., have achieved remarkable results. Especially its MW-80T cylindrical polishing machine, product quality has been equivalent to imported products. In addition, grinding machinery to the international enterprise standards to require their own, not only to stay in the achievements, but also in continuous innovation, continuous research, in the field of high-end polishing equipment has made one brilliant achievement after another. In addition, in terms of service, Haoyu polishing equipment never slackens, not only to customers with high-quality products, but also to bring good after-sales service, so as to keep up with international large enterprises and strive to achieve high-end industry. Grinding machine is the key equipment in the surface treatment industry. The performance, quality and reliability of surface treatment depend on the performance of the product. After years of development, China's polishing industry has formed a relatively mature industry scale. Based on the backward development of high-end grinding machines in China, the "Twelfth Five-Year Plan" clearly states that the country will play the guiding role of industrial policy to support the development of the surface treatment industry. Under the guidance of the state, the entry threshold of the bearing industry will be raised, the high production capacity of low-end products will be controlled, and the research and development of high-end polishing equipment will enter a high-speed stage. I believe that through the support of national policies and the continuous efforts of the surface treatment industry, under the leadership of a group of excellent companies like grinding machinery, my country's polishing equipment industry will usher in the spring of development and promote the development of my country's surface treatment and machinery and equipment manufacturing industry A new climax. To truly realize the brand building, the upgraded consumption concept has spread a strong marketing demand. Committed to a variety of image-building marketing campaigns, shaping brand advantage. Enterprises must be based on reliable product quality. Form a special product of its own. However, it has achieved hundreds of years of development abroad. Although, the development time of China's grinding machinery and equipment is only a few decades. Grinding machine industry research institutions believe that the development of China's grinding machinery enterprises still have a long way to go, but it is still a strong potential stock. There are not many independent research and development enterprises of grinding machinery technology. At present, there are very few independent research and development of grinding machines, and the technical content of grinding machines is not very high. A large number of low-level repetitive products hinder the development process and innovation pace of the entire grinding machine industry. Enterprises should be based on the status quo of the industry, around the needs of the industry, the first introduction-absorption-improvement-to create a new model of technological innovation.

Method of polishing and grinding

Method of polishing grinding: Grinding is the grinding tool (hereinafter referred to as the grinding tool) surface embedded abrasive or coated abrasive and add lubricant, under certain pressure, the tool and the grinding tool contact and do relative movement, through the abrasive action, from the workpiece surface cut a layer of very thin chip, so that the workpiece has a precise size, accurate geometry and high surface roughness. Its essence is to use free abrasive particles to carry out micro-cutting including physical and chemical comprehensive effects on the surface of the workpiece through the grinding tool. Features:(1) In mechanical grinding, the machine tool-tool-workpiece system is in an elastic floating state. (2) The workpiece to be ground is not subject to any force and is therefore in a free state. (3) The speed of the grinding movement is usually below 30 m/min, which is about 1% of the grinding speed. (4) When grinding, only a very thin layer of material can be cut off, so the heat generated is less, the processing deformation is small, and the surface deterioration layer is also thin. (5) There is residual compressive stress on the grinding surface, which is beneficial to improve the fatigue strength of the workpiece surface. (6) The operation is simple and generally does not require complicated and expensive equipment. (7) Adaptability is good. (8) grinding can obtain very low surface roughness. 1. Fluid polishing Fluid polishing is to rely on high-speed flow of liquid and abrasive particles to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power grinding is driven by hydraulic pressure, The liquid medium carrying the abrasive particles is caused to flow back and forth at high speed over the surface of the workpiece. The medium mainly uses special compounds with good flowability at lower pressure. (polymer-like substance) and mixed with abrasive, abrasive can be used silicon carbide powder. 2. Mechanical polishing Mechanical polishing is a method of polishing a smooth surface by cutting and plastic deformation of the surface of the material to remove the convex part after polishing, Generally use oilstone, wool wheel, sandpaper, etc., mainly manual operation, special parts such as the surface of the rotary body, Auxiliary tools such as turntables can be used, and the method of super-lapping can be used for high surface quality requirements. Super lapping is a special abrasive tool, In the polishing liquid containing abrasives, it is tightly pressed on the surface of the workpiece to be processed for high-speed rotating motion. Using this technology, the surface roughness of Ra0.008 μm can be achieved, which is the highest among various polishing methods. Optical lens molds often use this method. 3. Ultrasonic polishing The workpiece is placed in the abrasive suspension and placed together in the ultrasonic field, relying on the oscillation of the ultrasonic, The abrasive is ground and polished on the surface of the workpiece. Ultrasonic machining macro force is small, will not cause deformation of the workpiece, but tooling production and installation is difficult. Ultrasonic machining can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution, The dissolution products on the surface of the workpiece are separated, and the corrosion or electrolyte near the surface is uniform; Ultrasonic cavitation in the liquid can also inhibit the corrosion process, conducive to surface brightening. 4. Electrolytic polishing The basic principle of electrolytic polishing is the same as chemical polishing, that is, by selectively dissolving the small protruding parts of the surface of the material, Make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into two steps: (1) Macroscopic leveling dissolution products diffuse into the electrolyte, and the geometric roughness of the material surface decreases, Ra> 1μm. (2) micro light level anode polarization, surface brightness, Ra <1μm. 5. Fluid polishing Fluid polishing is to rely on high-speed flow of liquid and abrasive particles to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power grinding is driven by hydraulic pressure, The liquid medium carrying the abrasive particles is caused to flow back and forth at high speed over the surface of the workpiece. The medium is mainly made of special compounds (polymer-like substances) with good flowability at lower pressure and mixed with abrasives, The abrasive may use silicon carbide powder. 6. Chemical polishing Chemical polishing is to make the surface of the material in the chemical medium micro convex part of the concave part of the preferential dissolution, A smooth surface is thus obtained. The main advantage of this method is that it does not require complex equipment and can polish workpieces with complex shapes, Many workpieces can be polished at the same time with high efficiency. The core problem of chemical polishing is the preparation of polishing solution. Surface roughness obtained by chemical polishing Generally, it is several 10 μm. 7. Magnetic grinding and polishing Magnetic grinding and polishing is the use of magnetic abrasive under the action of a magnetic field to form an abrasive brush to grind the workpiece. This method has high processing efficiency, Good quality, easy control of processing conditions, good working conditions. With suitable abrasives, the surface roughness can reach Ra0.1 μm. The polishing in plastic mold processing is very different from the surface polishing required in other industries, Strictly speaking, the polishing of the mold should be called mirror processing. It not only has the very high request to the polishing itself but also to the surface flatness, There are also high standards for smoothness and geometric accuracy. Surface polishing is generally only required to obtain a bright surface. The standard of mirror processing is divided into four levels: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063 μm, due to electrolytic polishing, fluid polishing and other methods are difficult to accurately control the geometric accuracy of the part, The surface quality of chemical polishing, ultrasonic polishing, magnetic grinding polishing and other methods can not meet the requirements, so the mirror processing of precision molds Or mainly mechanical polishing.
