Vertical washing-resistant instrument

A scrub-resistant, vertical technology, used in instruments, scientific instruments, testing wear resistance, etc., can solve the problem of affecting the measurement results of the scrubbing instrument, and cannot truly reflect the wear resistance and washability of the test sample coating. It is impossible to truly measure the wear resistance of the coating and the washing resistance of the coating of the test sample.

Abstract

The invention discloses a vertical washing-resistant instrument which comprises a shell and a water receiving tank. The water receiving tank comprises an inclined water receiving tank; a pressing frame is fixed to the outer side of the inclined water receiving tank through a rapid clamping mechanism; a plurality of shower nozzles face the inclined water receiving tank; multiple rolling brushes aredriven by a rolling brush driving assembly to synchronously rotate, the multiple rolling brushes are driven by the rolling brush moving assembly to synchronously move along the inclined water receiving tank, and / or the multiple rolling brushes are driven by the rolling brush moving assembly to move in a direction perpendicular to the inclined water receiving tank. In the embodiment of the invention, a test sample plate is obliquely placed in the vertical washing-resistant instrument and the situation is close to the actual use situation of the test sample plate; the coating of the test sampleplate is brushed through the rolling brushes, the distance between the rolling brush and the test sample plate is kept constant in the process of brushing the test sample plate to guarantee that thesurface pressure of the rolling brush on the coating is kept stable, and the coating abrasion resistance and the coating washing resistance of the test sample plate are truly measured and reflected.

Description

technical field

[0001] The invention relates to washing resistance testing equipment, in particular to a vertical washing resistance tester. Background technique

[0002] The scrub resistance tester is a device for measuring the coating wear resistance and washability of the test sample. The scrub test tester on the market at present, the test samples are placed horizontally, and then brushed on the coating surface of the test sample. Make a linear reciprocating motion to wash the coating of the test sample. After the specified number of washings, if the coating surface of the test sample is not damaged and the color of the primer is not exposed, it is qualified.

[0003] However, in the actual application of the test sample, the test sample is generally not used horizontally. The test sample has an inclined angle to the ground, or the test sample is perpendicular to the bottom surface, resulting in a large difference between the measurement results of the scrub resistance i...
