Metal flat washers manufacturers, flat washers are healthier when washed like this [hardware]

Manufacturers of metal flat washers require a cleaning process for some flat washers that need to be quenched. Knowing these details can make flat washers cleaner and more beautiful. Xiaoshuo understands with you: 1. There are white residues on the high-strength flat washers. We analyzed with infrared spectrometer, and it turned out that these residues were phosphides. This shows that the flat washer has not been cleaned with acidic detergent and the concentration of lye in the rinsing tank has not been checked frequently. 2. For large-size flat washers, polymer aqueous solution is often used for quenching, and alkaline cleaning agent is used to clean and rinse before quenching. After quenching, the fasteners have rusted inside. In fact, in addition to iron oxide, there are sodium, potassium, and sulfur. This indicates that there is an alkaline cleaning agent on the inside of the fastener, which is likely to be potassium hydroxide, sodium carbonate or similar substances, which is easy to rust. 3. Solid matter appears on the surface of the flat washer. This is because the fasteners are not thoroughly rinsed for the residual silicate and iron oxide on the surface of the fasteners. Hardware, 15 years of ingenuity and focus on metal flat gasket manufacturers, custom production of 20,000+ sets of molds, monthly processing capacity of 100+ sets of stamping dies, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, and 16 quality inspections. . It can quickly solve the urgent problem of flat washer time, solve the problem of stamping accuracy, and solve the quality problem for you. Choose, choose rest assured!
