Have you ever know what the hand abrasion tester is for ? The hand abrasion tester is designed to perform real life testing of finished products or lab samples in respect of resistance to hand abrasion. The hand abrasion tester is set-up to exactly reproduce the complex chemomechanical system of human hand abrasion according to international standards. The flexible design of the tester allows various mechanical and chemical options.
When humans touch a surface they expect a feedback. Our fingers are not sensitive in regards of pressure, however they are very sensitive for shear and friction. Therefore, when we need feedback from a surface we always perform a sliding motion by touching a surface.The tester exactly reproduces the act of a human touch on the surface.
The human hand consists of a visco elastic material containing a rough and structured surface. The visco-elasticity of the finger is reproduced by a silicone material, the structure of the skin is simulated by a normed cotton textile. In addition, sweat or hand cream can be added to create a severe chemical environment.
The main working principles of Universal finger friction tester is through a test head, plus a certain amount of pressure, and carry a variety of standard test cloth surface of the material / coating to angle standards for automatic circulating friction.Test conditions can be customized, including dry and liquid under conditions (sweat, emulsion) test.
