Machine d'essai d'usure de tuyau en caoutchouc: spécifications et; Principes

Normes applicables:

• ASTM D3806: Rubber Property—Abrasion Resistance (Rotary Drum Abrader Method).
• ISO 4649: Rubber—Determination of Abrasion Resistance Using a Rotating Cylindrical Drum Device.
• DIN 53516: Testing of Rubber—Abrasion Resistance (Rotary Drum Abrasion Test).

Paramètres principaux(tableau 1):

Principe de fonctionnement:
The tester uses a rotating cylindrical drum wrapped with abrasive sandpaper. A rubber hose specimen is pressed against the drum under a controlled load, creating friction as the drum rotates. The test duration, load, and speed are preset via a digital interface, while a counter tracks revolutions. Advanced models integrate temperature control to simulate extreme operational conditions.

Principe d'essai:
Abrasion resistance is quantified by measuring the mass loss or coating thickness reduction after a specified number of cycles. The abrasion index (volume loss per 1000 cycles) is calculated to compare material performance. For example:

• Mass Loss Method: Index=CyclesΔm(g)×1000
• Thickness Method: Index=CyclesΔT(mm)×1000

Application:

• Automotive Hoses: Testing fuel lines, brake hoses, and cooling systems for abrasion from engine vibrations.
• Industrial Hoses: Evaluating hydraulic hoses exposed to repetitive friction in construction equipment.
• Aerospace Hoses: Assessing durability against sand and debris in aircraft fuel systems.

By optimizing coating formulations based on test results, manufacturers enhance product lifespan and safety. This machine’s precision and compliance with global standards make it a cornerstone of modern rubber testing laboratories.
