In the 1960s, through Electroplating equipment Polymers (relative molecular weight 83 or above) were prepared by polymerization with catalyst. Polypropylene modified plastics are referred to as polypropylene for short. This is a process of cracking oil and natural gas to produce propylene. Its main feature is low relative density, only 0.90.91; Good heat resistance, can use more than 1001, no external force, 1501 does not deform; Good resistance; High frequency electrical performance; Low water absorption. Therefore, it has a wide range of industrial applications. It can be made into various containers, and can also be used as container lining, coating, mechanical parts, flanges, automobile parts, etc. Its disadvantages are high shrinkage rate, easy shrinkage depression of wall thickness, low temperature brittleness, etc.
According to the user experience, the advantages and disadvantages of various dung utensils are pointed out. Suggestions on the selection of vibrating screen and electroplating process are put forward. It is expected that vibration electroplating technology will be widely used in China. Vibration electroplating is a new process for electroplating small parts by vibration equipment. The types and working principles of electromagnetic vibration electroplating equipment currently used in China are briefly introduced. Vibration electroplating is a new electroplating technology widely used abroad in the early 1980s. Since the late 1980s, China has introduced vibration electroplating technology and equipment, which are mainly used in the electroplating field of electronic components. In the 1990s, Canadian vibration equipment manufacturers and Hong Kong businessmen established Baodi Electroplating Equipment Company in Dongguan, Guangdong Province. In recent years, Shenzhen Fenghua Electroplating Equipment Company and Hebei Dashun Electroplating Equipment Factory in China have also started to produce and sell this kind of electroplating equipment, because the coating quality of electroplated parts using this technology is significantly better than that of conventional methods. Barrel plating and hanging plating have made this technology develop rapidly in China in recent years. From the first two factories with such equipment to now, dozens of electronic product manufacturers have used this electroplating technology as the surface treatment technology for small electroplated parts. Vibration electroplating has a good application prospect in China. In order to promote more electroplating workers to use this technology. This paper briefly introduces the equipment and technology of vibration electroplating in China.
The mechanical strength and electrical properties of the plastics were improved after electroplating. Mechanical strength improvement rate. They are all 25 times the elastic coefficient. When the heat resistance of 1015 increases, for example, when bright nickel is plated with 30 ^ 11 nickel of 7.5 ^ 111 chromium 0.25 on the plastic, the melting point 1701 will not deform. One is a manufacturer of plastic electroplating equipment. This process is applicable to ordinary plastics. There are two types of electroplated 9 plastic. The advantages of plastics are maintained, but the dimensional accuracy is poor and roughening is difficult. In China, it was once thought that plastic was not suitable for electroplating, that is, this kind of plastic. In fact, even ordinary plastics can be successfully electroplated as long as the key points of the process are mastered. The other is electroplating grade plastics. The improved plastic was specially designed for electroplating in the 1970s and 1980s, but there is no such plastic in China. At that time, the so-called modified polypropylene was not modified by electroplating and could not be electroplated into electroplating grade plastic.
In each process of electroplating equipment, the filter pump pumps the solution from the tank into the treatment tank, and then circulates the solution into the tank through filtration and treatment. The vibration source of this production line is equipped with two or more vibrating heads on the production line of the working trough. When the first vibrating head completes one process+the second and third vibrating heads can be carried out in sequence, the vibration source is installed under the processing trough of each process of the production line of the working trough, and the crane drives multiple vibrating screens to carry out multiple processes at the same time. Work. Compared with the first two kinds of equipment, the production capacity of this type of production line can be rapidly improved. Most of these production lines are equipped with special computers. In the early 1990s, Guiyang Zhenhua Electric Appliance Company introduced this production line from abroad. At present, both Baodi and Fenghua have built this production line in China, most of which are the vibration sources of this type of electroplating tank. The vibration plating process is the same as the traditional barrel plating process. Users can select appropriate barrel plating process for vibration plating according to their needs. In order to ensure the quality of electroplated parts, especially the electroplating of precious metals, it is recommended to use the zhuanli electroplating process and additives from well-known manufacturers. The vibration gold plating process of our factory adopts the gold nickel alloy plating process of LILE Company. The electroplating effect is good and the quality of the coating is satisfactory. At present, Ankellen Company has introduced a special vibration electroplating gold plating process, which not only retains the advantages of compact and bright appearance of vibration electroplating coating, but also improves the dispersion ability of the coating.
