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, cauciuc, cauciucuri, benzi transportoare, benzi transportoare, tălpile, soft synthetic leather, leather and other materials wear test, with good reproducibility and easy operation characteristics. Printre ei, 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, pe un anumit nivel de tifon, proba cilindrică este tăiată în cruce și măcinată pe suprafața tifonului pentru o anumită cursă. By measuring the mass wear amount of the sample, the volume wear amount is calculated from the density of the sample. Pentru a face testul comparabil, standard rubber must be used at the latest. Rezultatele testului sunt exprimate ca volumul relativ de uzură bazat pe tifonul verificat sau ca cantitatea de uzură relativă la un adeziv standard.

DIN abrasion testing machine main functional features:
1. Start the switch.
2, grinding sand ring: 60 șmirghel (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, greutate: 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, iar după o anumită distanţă de frecare, evaluate the surface wear condition of the specimen, the loss of weight, the loss of volume, grosimea uzurii și alte caracteristici, 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.
