China Electroplating Network Information : Recently , Xingtai Iron and Steel Co., Ltd. Wire refining company in response to market demand, the development of alkaline zinc plating process , to enhance product quality to provide a support.
With Xing steel wire refining company cars , agricultural machinery market continues to develop , users of the exposed parts of corrosion resistance, appearance requirements also rising. Original surface machining process using potassium chloride acid zinc , the coating process to produce products with fast , shiny , etc., but because of the zinc layer is not continuous grain rough and loose zinc corrosion resistance is poor. Have high corrosion resistance and good brightness , etc. alkaline zinc plating process of the trial and research and development is imminent.
Since February , the company cut the wire spool as a trial product, began planning process and alkaline zinc production model , the first of the original 7 manual trunking body transformation, increased two washed and expanded the original galvanized tank volume , the use of financial zinc and galvanized synchronization is complete , solving the problem of financial resources, lack of equipment under the zinc line, while according to the word wheel rack frame structure be modified , use the industry's work hanging hook but in the trial process appeared high and low potential areas deposited layer thickness difference is big , low potential areas poor dispersion conditions. To solve this problem , the technician through trial and error , the choice of methods to increase the auxiliary anode , the hole in order to improve the efficiency of current conduction region , to ensure that the overall passivation layer of zinc spool evenly coated consistent with the mass production workers technology and production conditions of the word wheel.
To further improve the efficiency of research and development , rapid response to market requirements, the company's technical and production personnel carriers have begun galvanizing topics such as additives and current efficiency testing and analysis , technical parameters and the accumulation of experience , to provide support for the post- production .
