Drying method, drying system and zinc-nickel electroplating process in electroplating zinc-nickel process

Abstract

The invention relates to the technical field of electroplating technology, in particular to a drying method and a drying system in the electro-galvanizing-nickel process and the electro-galvanizing-nickel process. The drying method includes the following steps: (1) hanging the washed product and shaking the product to shake off most of the liquid droplets on the surface of the product; (2) drying the product by wind blowing the product. The product has just been taken out of the water, and there are a large number of droplets on the surface. By shaking, most of the droplets on the surface of the product can be shaken off, which is very conducive to the rapid drying in the later stage; then the product is blown by wind to speed up the evaporation of the droplets on the surface of the product. Further speed up product drying and improve the efficiency of electroplating process. The shaken droplets can also be recycled, which not only saves water resources, but also saves drying power, and the whole drying method is very simple, which is beneficial to popularization.

Description

technical field [0001] The invention relates to the technical field of electroplating technology, in particular to a drying method and a drying system in the electro-galvanizing-nickel process and the electro-galvanizing-nickel process. Background technique [0002] Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . However, with the development of science and technology, the hardness, wear resistance, and corrosion resistance of aluminum alloys are increasingly unable to meet the application requirements. Nickel plating on the surface of aluminum and aluminum alloy can significantly improve the surface hardness, wear resistance and corrosion resistance, and also endow the aluminum alloy wit...

Problems solved by technology

The commonly used method is to dry naturally or put it in an oven. It takes a long time to dry naturally, especially in humid weather, which will seriously affect the entire process. If it is dried in an oven, the product A large amount of water remains on the surface, which requires relatively high requirements for the oven, and the space in the oven is limited. In mass production, the efficiency of the overall process is also relatively low.
