Three effective tests for washable, brush & Wear testing machines

Washable, Brushable & Abrasion Tester

Improving mechanical wear resistance is a key requirement for a wide variety of products. From paint to clothing, leather to upholstery, keyboards to plastic toys, a product's resistance to abrasion is an important characteristic.

There are various test methods related to the concept of "frictional wear". Other detection methods are based on projecting abrasive particles onto the sample to be tested. These techniques provide us with some valuable information about materials and fabrication processes.

There are three valid tests, namely:

Friction: the movement of one part relative to another

Scrubbing: moving a wet or dry brush or sponge over the sheet to be tested

Impact: Abrasive particles are projected onto the sample to be tested

Mechanical testing makes it difficult to correlate test performance with real daily wear and tear, but accurate comparisons can still be made.

definition:

Washability:

The ability of a coating to withstand cleaning by dry or wet scrubbing action. Scrubbing effectiveness can be judged by the weight loss, gloss loss or thickness loss of the coating after the scrubbing process.

Brush/sponge resistance:

That is, the degree to which the wall covering resists cleaning by a brush or sponge, usually a sponge, using a fixed set of experimental conditions and methods, such as number of turns, sponge weight and size, etc.

Abrasion resistance:

The ability of a coating to withstand the wear and tear of a particular material rubbing against its surface. Erosion is the erosion of material on a solid surface under the action of another solid.
