Abstract

The invention provides a surface treatment process for Zn alloy handles and solves the problems of the prior art, such as rust formation, poor color of work pieces or instruments and rough surface of products. The method includes the following steps: brass plating step: uniformly plating a brass coating on the surface of the Zn alloy handle by electroplating process; paint spraying and drying steps: uniformly spraying paint on the surface of the brass-plated handle and oven-drying the paint on the surface of the handle; polishing and varnishing steps: polishing the surface of dried handle and uniformly spraying varnish paint on the surface thereof; passivation step: immersing the handle in a passivation liquid to passivate, the passivation liquid is a color paste obtained by diluting an acrylic paint with water. The surface treatment process for Zn alloy handles has the advantages of good effect of ancient imitations, beautiful appearance, simple operation and low treatment cost without paint stripping and color fading.

Description

technical field

[0001] The invention relates to a surface treatment process of a metal piece, in particular to a surface treatment process of a zinc alloy handle. Background technique

[0002] Most of the drawer handles on the market are made of aluminum alloy, but because of the difficulty and high cost of processing them into curves or complex products with various patterns, the aluminum alloy handles on the market are all straight. In practical application, it has great limitations and can only be used in some more modern products, and cannot meet the needs of some furniture with antique colors or more luxurious places.

[0003] Zinc alloy is an excellent casting alloy, which is easy to process into workpieces with various curves, complex structures and high precision, so it has wide applicability.

[0004] However, zinc alloys are not resistant to wear, and zinc alloys are directly exposed to the air, which is easily corroded by humid atmosphere. In order to overcome th...
