The vending machine and the advantages and disadvantages of the chrome plated spring and electrophoresis in the spring

As we all know, with the development of economy of people's living standard is increasing day by day, the vending machine more and more appear in various places. The vending machine for a new retail has incomparable advantage over traditional retail, can open all year round, 24 hours can be more convenient services to customers, operating member can also periodically according to the vending machine background to replenishment, also greatly reduces the labor costs. The vending machine has a lot of kinds, common on the market is selling drinks snake aisle of the vending machine and spring track aisle of the vending machine. Here we mainly talk about some knowledge of the spring spring in the aisle. A friend asked for spring aisle is a motor module and spring, have nothing to discuss. In fact, a lot of things on the surface of seemingly mundane, but there are a lot of knowledge. From the material, generally divided into carbon steel, manganese steel, stainless steel, stainless steel cost is not generally high, the meaning is not big. Low-end spring have use carbon steel ( Is the most common spring steel) Commonly used manganese steel, a little better ( High-speed rail is manganese steel) Manganese steel, corrosion resistance and better rigidity, tenacity is out of shape not easily. In order to better way corrosion, generally involves two important surface treatment technology, electroplating and electrophoresis. Plating spring electrophoresis spring plating is using the electrochemical principle in the surface corrosion resistance of metal plating last, general nickel plating, chrome is given priority to. The chrome plated look pretty good anticorrosive, but the shortcoming is also very obvious, electroplating can seriously pollute the environment. Electrophoresis is electrophoresis paint here, under the action of additional dc power supply, colloid particles in the dispersion medium to the cathode or anode for directional movement, the use of this principle for plating lacquer, low pollution, save energy, save resources, and many other advantages. The vending machine aisle of the spring also better distinguish from the appearance, electroplating the surface of the spring is bright metal color, like a mirror, electrophoresis spring is black, the surface with a layer of uniform film very much. Nearly two years the environmental protection is valued, so the vending machine spring plate for less and less, are generally electrophoresis paint. In brief, on the premise of not affect use, electrophoresis process cheaper, and more energy conservation and environmental protection. （ Note: the vending machine = vending machine = vending machines, automatic vending machine have different address! ）
