trichloride aqueous solution experimental conclusion
　　trichloride aqueous solution quenching medium cooling characteristics between water and oil, through testing and production applications, fully meet the requirements of use. And the raw materials are simple, the price is cheap, the composition is stable, no pollution, and it is easy to manage and control. The liquid consumed in use can be added with the liquid of the same composition ratio. Triethanolamine in the solution can not be added, adding triethanolamine is mainly used for workpiece rust. Because ZnCl2 in the solution can remove oxide on the surface of the workpiece at high temperature, the quenched surface is silvery white, while the addition of triethanolamine produces a gray anti-pound film on the surface, which can be kept free from rust for a week. If surface treatment such as electroplating is required immediately after quenching, triethanolamine may not be added.
