Embodiment Construction
[0016] Such as figure 1 A testing mechanism for the abrasion resistance of the surface coating of a profile is shown, comprising a support frame 1, a sand-containing funnel 2 arranged on the upper part of the support frame 1, the discharge port of the sand-containing funnel 2 is connected to the upper end of a pipe 3, and the lower end of the pipe 3 is provided There are artifacts. The inner angle of the sand hopper 2 can be 60°, the discharge diameter can be 5mm, and the maximum capacity of the sand hopper 2 is 7.5L. The sand hopper 2 is provided with a flow regulating valve 4 to control the leakage rate. By adjusting the flow regulating valve 4, the flow of the sand material leaked is controlled to reach the specified flow rate (which can be 310g / min-330g / min). The workpiece should be cut on the decorative surface of the profile. When it is not possible to sample directly on the profile, a flat sample made of the same material and the same processing conditions as the product...
