​Protective gloves for pickling

Protective gloves for pickling

For the galvanizing industry, it can be divided into two types: electro-galvanizing and hot-dip galvanizing. The labor protection products used are mainly acid-alkali-proof gloves. At present, PVC-dipped anti-slip gloves are mostly used, which are not only acid-alkali-proof but also acid-alkali-proof. It has the function of anti-slip, and the operator needs to wear gloves for operation during the pickling process. Both types of galvanizing are required. The difference between the two types of galvanizing is as follows: the concept is different, hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing. It is an effective metal anti-corrosion method and is mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts in a molten zinc solution at about 500 ° C, so that the surface of the steel parts adheres to the zinc layer, so as to achieve the purpose of anti-corrosion. Electrogalvanizing, also known as cold galvanizing in the industry, is the process of using electrolysis to form a uniform, dense and well-bonded metal or alloy deposition layer on the surface of the workpiece. Compared with other metals, zinc is a relatively cheap and easily plated metal. It is a low-value anti-corrosion coating and is widely used to protect steel parts, especially against atmospheric corrosion, and for decoration. The process is different, the process of hot-dip galvanizing: pickling of finished products - washing - adding plating solution - drying - rack plating - cooling - chemical chemical - cleaning - polishing - hot galvanizing is completed. Electrogalvanizing process flow: chemical degreasing - hot water washing - washing - electrolytic degreasing - hot water washing - washing - strong corrosion - washing - electrogalvanized iron alloy - washing - washing - light - passivation - washing - drying. The process is different. There are many processing techniques for hot-dip galvanizing. After the workpiece is degreasing, pickling, dipping, and drying, it can be immersed in the molten zinc bath. Galvanized, like some hot-dip pipe fittings are processed this way. Electrolytic galvanizing is processed by electrolytic equipment. After degreasing, pickling and other processes, it is immersed in a solution containing zinc salt, and the electrolytic equipment is connected. During the current directional movement of the positive and negative electrodes, the zinc layer is precipitated on the workpiece. . The appearance is different, the overall appearance of hot-dip galvanizing is slightly rougher, which will produce process water lines, dripping tumors, etc., especially at one end of the workpiece, which is obvious and the whole is silvery white. The surface layer of electro-galvanizing is relatively smooth, mainly yellow-green, of course, there are also colorful, blue-white, white with green light, etc. The whole workpiece basically does not appear zinc nodules, agglomeration and other phenomena.
