Машина для испытания на износ покрытия резиновых шлангов: спецификации и; Принципы

Применимые критерии:

The machine adheres to standards such as ASTM D3806 (Rubber Property—Abrasion Resistance), ISO 6945 (Rubber-Coated Fabrics—Abrasion Resistance), and SAE J300 (Automotive Hose Testing). It also supports custom protocols for specialized applications.

Основные параметры(Таблица 1)

Принцип работы:
The tester uses a rotating abrasive wheel (e.g., sandpaper) to apply controlled friction to the hose coating. A specimen is clamped horizontally and subjected to reciprocating or circular motion against the abrasive surface. The load and speed are preset via a digital controller, while a counter records cycles until coating failure (e.g., exposure of base material).

Принцип испытания:
Измерение износостойкостиweight lossИлиthickness reduction of the coating after a defined number of cycles. The machine calculates the Индекс износа (volume loss per unit distance) to compare material performance. Advanced models integrate laser sensors for real-time thickness monitoring, enhancing precision.

Применение:
Widely used in R&D and manufacturing of hydraulic hoses, fuel lines, and industrial hoses, this tester ensures compliance with safety standards and extends product lifespan by optimizing coating formulations.
