The existence of steel products is the key to the quality life of today’s people. With the continuous development of the social economy, the steel market is also growing. U-shaped steel is a typical existence. The method and method of specific degreasing work for u-shaped steel is small. Edited for you as follows.

Chemical degreasing generally refers to treatment with an aqueous solution of an alkali an an alkaline salt to remove grease, which is produced by the action of an oil film under the action of a surfactant an a base, mechanism of removing alkaline oil from steel surface by using alkaline aqueous soluction. Electrochemical degreasing is a process of mechanically separating the oil film attached to the surface of the u-shaped steel and accelerating the emulsification of the oil by using hydrogen gas deposited on the cathode or oxygen is deposited on the anode.

Electrochemical degreasing method can be divided into anode electrolytic degreasing, cathodic electrolytic degreasing and mixed polar electrolytic degreasing according to the electrode polarity of the object to be cleaned.

Usually, the surface of the u-shaped steel adheres less grease, and the furnace welded pipe is formed at a high temperature, and may be in contact with the grease during the finishing process, but this can be avoided, and usually there is no degreasing process. In short, whether to use degreasing, it is determined according to the specific conditions of the surface of the raw material u-shaped steel.

Through the above summary, I hope to help customers and friends understand the use of u-shaped steel, enrich your purchase and installation support, to know about other aspects of u-steel, you can call our company.
