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

Abstract

The invention relates to the technical field of electroplating processes, in particular to a drying method and drying system in the electroplating zinc-nickel process and the electroplating zinc-nickel process. The drying method comprises the following steps: (1) suspending a washed product, shaking the product, and shaking off most liquid drops on the surface of the product; and (2) drying the product by air blowing. When the product is just fished out of the water, a large number of liquid drops are arranged on the surface of the product, most of the liquid drops on the surface of the product can be shaken off in a shaking mode, and rapid drying in the later period is convenient to carry out; and the product is blown by air, so that the evaporation of liquid drops on the surface of the product is accelerated, the drying of the product is further accelerated, and the electroplating process efficiency is improved; and the shaken liquid drops can also be recycled, not only is the waterresource saved, but also is the drying electric energy saved, and the whole drying method is very simple and is beneficial to popularizing.

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.
