The surface treatment of drilling anchor bolt fasteners refers to the whole process of covering the fastener surface in a certain way. After surface treatment, the appearance of the fastener is more beautiful and generous, and the corrosion resistance of the fastener itself is improved. Fasteners have several surface treatments.
Bolt manufacturer
1. Electroplating of fasteners: electroplating of fasteners refers to infiltrating the components that must be plated into a special saturated solution with some accumulated metal compounds. After using the current amount according to the solution, the metal material chemicals in the saturated solution deposit and adhere to the penetration part of the fastener. Fastener electroplating usually includes hot galvanizing, copper, nickel, chromium, copper nickel alloy, etc.
2. Hot dip galvanization of fasteners: The hot dip galvanization of fasteners is to infiltrate fasteners made of carbon steel into a molten zinc hot dip galvanization bath with a temperature of about 510 ℃, so that the iron zinc alloy material on the fastener surface changes to passive zinc, thus completing the actual effect of surface treatment. The price of hot-dip galvanizing of fasteners is higher than that of electroplating, about 1.5 to 2 yuan per kilogram.
3. Mechanical equipment plating of fasteners: mechanical equipment plating of drilling anchor bolt fasteners. It represents that the fastener surface is impacted by the coated metal powder according to the corresponding physical and organic chemical methods, which promotes the coated metal material to be spray welded on the fastener surface according to the requirements. Produce plating to achieve the actual effect of surface treatment. Mechanical equipment plating of fasteners is key to the application of screw, nut and washer accessories.
