Visão geral da máquina de teste de abrasão DIN:
O instrumento é usado principalmente para determinação da resistência ao desgaste da sola de borracha ou plástico, sola de borracha ou plástico deve ser usada com o número especificado de fricção de lixa, como uma determinação da resistência à abrasão do único material, Máquina de teste de abrasão DIN em linha com DIN-53516,ISO/DIS-4649,GB-9867. A máquina de teste de abrasão DIN é adequada para materiais elásticos, borracha, pneus, correias transportadoras, correias transportadoras, solas, couro sintético macio, teste de desgaste de couro e outros materiais, with good reproducibility and easy operation characteristics. Entre eles, 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 sandpaper (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, peso: 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, e depois de uma certa distância de atrito, evaluate the surface wear condition of the specimen, the loss of weight, the loss of volume, a espessura do desgaste e outras características, 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.
