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

[0019] Such as figure 1 The sand falling test machine shown includes a support frame 1 and a sand holding funnel 2 arranged on the upper part of the support frame 1. The discharge port of the sand holding funnel 2 is connected to the upper end of the conduit 3, 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, a flat sample made of the same material and the same processing conditions as the product can be used. The workpiece is a profile ...

Abstract

The invention discloses a shakeout testing machine which comprises a support frame and a sand holding funnel which is arranged on the upper portion of the support frame. The discharge outlet of the sand holding funnel is connected with the upper end of a guide pipe, and a workpiece is arranged under the lower end of the guide pipe. By the above structure, the shakeout testing machine has the advantages that abrasion performance of a profile surface coating is accurately measured through weight of the worn-through profile surface coating, and sand concentration is higher; a rotating shaft structure facilitates adjustment of the tile angle of a profile board, and mounting of the profile board is facilitated; a positioning needle features in ensuring that sand drops down freely to touch with the profile board with the same height each time of sampling, and errors generated due to different height are reduced; the guide pipe prevents influence of wind power to the sand freely dropping down; a lifting mechanism lifts a sand weighing mechanism to the position of the sand holding funnel, the sand in the sand weighing mechanism flows to the sand holding funnel, and recycling is realized.

Description

technical field [0001] The invention relates to 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 even cannot detect the wear resistance of the surface coating, which is serious...
