Problems solved by technology

Since the specific method and scope of the determination of the sand concentration ratio are not specified in the wear resistance test method stipulated by the anodic oxide film, the results of the wear resistance test are different, and some even cannot detect the wear resistance of the surface coating, which is serious. It affects the accurate detection of the surface quality of profiles, and brings certain troubles to aluminum profile manufacturers and users

Embodiment Construction

[0015] Such as figure 1 Shown is a method for testing the wear resistance of profile surface coatings using a falling sand testing machine. The falling sand testing machine includes a support frame 1, a sand holding funnel 2 arranged on the upper part of the support frame 1, and the discharge port of the sand holding funnel 2 is connected to the The upper end of the conduit 3 is connected, and a workpiece is arranged below the lower end of the conduit 3 . The inner angle of the sand-filling funnel 2 can be 60°, the discharge diameter can be 5mm, and the maximum capacity of the sand-filling funnel 2 is 7.5L. The sand filling funnel 2 is provided with a flow regulating valve 4 to control the leakage rate. By regulating the flow regulating valve 4, the flow of sand material leaking is controlled to reach a specified flow rate (can be 310g / min-330g / min). The workpiece should be cut on the decorative surface of the profile. When the sample cannot be directly sampled on the profile...

Abstract

The invention discloses a method for testing wear resistance of a surface coating of a profile via a falling sand tester. The method includes the steps of adjusting tilting angle of a profile plate via a spindle of a sample support, loading a sand funnel with sand, allowing the sand to flow out of a discharge outlet of the sand funnel and perpendicularly fall in a guide tube onto the profile plate along a sand guide pin, allowing the sand to slide to a guide plate along the profile plate and enters a sand box from the guide plate, allowing the sand to continue falling until that a falling sand stress point of the profile plate is worn through, closing a throttle valve to stop sand falling, metering the weight of the sand via a weigher, and measuring the wear resistance of the surface coating of the profile plate. The method has the advantages that the wear resistance of the surface coating of the profile plate is accurately measured according to the weight of the worn-through surface coating of the profile plate, and the sand is highly concentrated; the guide tube prevents wind from affecting the sand in free falling, a lifting mechanism lifts a sand weighing mechanism to the sand funnel, and the sand in the sand weighing mechanism flows into the sand funnel for reuse.

Description

technical field [0001] The invention relates to a method for testing the wear resistance of profile surface coatings by using a falling sand testing machine. Background technique [0002] Aluminum alloy building profiles are mainly used in the construction industry and the field of housing construction. They have the advantages of light weight, beautiful structure, corrosion resistance, and simple processing. With the change of the environment and the improvement of living standards, the requirements for the corrosion resistance of the surface of aluminum alloy building profiles are getting higher and higher, so the measurement of the wear resistance of the surface coating of aluminum alloy building profiles is particularly important. Since the specific method and scope of the determination of the sand concentration ratio are not specified in the wear resistance test method stipulated by the anodic oxide film, the results of the wear resistance test are different, and some e...
