DH-2139GS dry wet abrasion resistance wiping decolorization testing machine

This instrument is suitable for testing the friction resistance of materials such as leather, insoles, insoles, textiles, straps, trademarks, cardboard, etc. The degree of damage and discoloration after friction can be divided into two types: dry and wet friction methods.

Compliant with ISO-11640, GB/T3903.31, QB/T2537TheQB/T2882、ENISO20344、DIN53339、SATRA PM173，177。

Experimental principle:

Product features: Easy to operate, the counter has a power-off memory function.

Experimental principle: This instrument is an integral instrument. Dry or wet wool felt is placed in the groove on the lower surface of the friction hammer, and a weight of a specified weight is placed above the friction hammer. Under a specified pressure, a dry or wet white wool cloth is wrapped around the surface of the friction hammer against the leather surface. The sample surface is rubbed back and forth at a specified speed for a certain stroke. After reaching the specified number of times, the damage and degree of discoloration on the sample surface are observed.

Sampling requirements: length of120mm， Width of 20mm

Result judgment: Compare the color changes on the surface of wool felt and leather with gray sample cards, determine the grade, and record any visible changes or wear on the leather surface.
