Vertical washing-resistant instrument

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...

Problems solved by technology

[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, As a result, the measurement results of the scrub resistance instrument are quite different from the actual conditions of the test sample, and the measurement results of the scrub resistance instrument cannot truly reflect the coating wear resistance and coating washability of the test sample.

[0004] In addition, in the current scrub resistance tester on the market, the brush has the problem of unstable pressure during the process of scrubbing the test sample, that is, the brush exerts a large pressure on the surface of the coating The time is small, which affects the measurement results of the scrub resistance instrument, and cannot truly measure the coating wear resistance and coating washability of the test sample.
