DIN Abrasion testing machine Overview:
The instrument is mainly used for rubber or plastic outsole wear resistance determination, rubber or plastic outsole must be used with the specified number of sandpaper friction, as a determination of the sole material abrasion resistance, DIN abrasion testing machine in line with DIN-53516,ISO/DIS-4649,GB-9867. DIN abrasion testing machine is suitable for elastic materials, guma, tires, przenośniki taśmowe, przenośniki taśmowe, soles, miękka skóra syntetyczna, test zużycia skóry i innych materiałów, with good reproducibility and easy operation characteristics. Pomiędzy nimi, wear resistance is a physical parameter to measure the wear resistance of the material when sliding or rolling friction occurs between the material and the contact surface, and is an important physical property index of rubber materials.

DIN Abrasion testing machine principle:
Under a certain load, on a certain level of gauze, the cylindrical sample is cross-cut and ground on the surface of the gauze for a certain stroke. By measuring the mass wear amount of the sample, the volume wear amount is calculated from the density of the sample. In order to make the test comparable, standard rubber must be used at the latest. The test results are expressed as the relative volume wear amount based on the checked gauze or as the wear amount relative to a standard adhesive.

DIN abrasion testing machine main functional features:
1. Start the switch.
2, grinding sand ring: 60 papier ścierny (size is 400㎜ wide ×472.5㎜ long) with double-sided tape to fix it on the runner, its gap can not exceed 2㎜.
3, the test piece holder: clamp the test piece, the size of the test piece is 16㎜ in diameter, 6 ~ 16㎜ in thickness (not enough to paste).
4, waga: the weight of the holder is 2.5N, and 2.5N and 5N can only be used arbitrarily.
5, the specimen rotation rack: make the specimen rotation.
6, dust cover: protect the transmission part and prevent dust and improper loss.
7, round cutter: used to cut out the diameter of 16㎜ of the test piece, the grip is 13㎜, can be used with the general drilling machine.
8. Its main function is to use specific sandpaper to rub the surface of the specimen, i po pewnym dystansie tarcia, evaluate the surface wear condition of the specimen, the loss of weight, the loss of volume, grubość zużycia i inne cechy, and evaluate the wear resistance characteristics of the material by comparing the standard glue.
9, so that there are two modes of wear and tear damage, this test method with standard glue and specific gravity balance device can calculate the standard wear volume loss, is the most accurate and current in the relevant common specifications.
