Device for salt mist tolerance test of aluminum alloy workpiece and test method using device

Abstract

The invention discloses a device for a salt mist tolerance test of an aluminum alloy workpiece. The device comprises a steam box, a fan, a burner, a heat exchanger, a vertical lifting door and a heatable water tank, wherein the steam box comprises a workpiece steaming chamber, an air return chamber and an air supply chamber; a test method of salt mist tolerance of an aluminum alloy workpiece usingthe device comprises the following steps: (1) preheating of the steam chamber; (2) entering of the workpiece into the steam chamber; (3) primary flushing; (4) heating treatment; (5) moisturizing treatment; (6) secondary flushing; (7) discharging of the workpiece out of the steam chamber. According to the test method of salt mist tolerance of the aluminum alloy workpiece, an aluminum alloy workpiece test enhanced than before can be effectively realized, so that the workpiece can endure long-time salt mist resisting test without being damaged, and the quality of the final product is remarkablyimproved; the device for the salt mist tolerance test of the aluminum alloy workpiece is perfect in structure and convenient to use and is completely suitable for the test method; a safe and effectivetreatment environment is provided, the product quality is effectively improved, and the method and device are worthy of popularization and application.

Description

Technical field [0001] The invention relates to the technical field of aluminum alloy product processing, in particular to a device for salt spray resistance test of aluminum alloy workpieces and a test method using the device. Background technique [0002] In the production and processing of aluminum alloy products such as decorative strips for luxury cars, salt spray resistance tests are required to obtain high-quality products with good gloss and corrosion resistance. However, the related equipment structure in the current production and processing is not perfect, or rarely can meet the relatively higher international standards, the product quality is not good, and the competitiveness is not high enough. This is an urgent issue to be solved. Summary of the invention [0003] One of the technical objectives of the present invention is to provide a device for the salt spray resistance test of aluminum alloy workpieces, which solves the problems of imperfect structure of tradition...
