Shoe Abrasion Tester QB/T4329-2012
Product Introduction:
The whole shoe wear testing machine is used to test the wear resistance of soles and sole pieces. The principle is to press the rotating grinding head vertically above the sample, and carry out rotary wear test on the test sample at a certain load weight and a speed of 191r/min. After the test is completed, the wear length of the sample is measured to evaluate whether the sample is qualified.
Reference standard:
GB/T 3903.2-2017. QB/T4329-2012 and other standards
Product Advantages:
Measures Key Durability: Quantifies the wear resistance of shoe soles, a direct indicator of footwear durability and expected lifespan.
Standard Compliant: Designed to meet national standards (GB/T 3903.2. QB/T 4329) for shoe wear testing.
Controllable Test Parameters: Allows for precise control of load, speed, and test time according to standard requirements.
Uses Standardized Abrasive: Utilizes a grinding wheel with detailed specifications to ensure consistent abrasive action.
Provides Quantitative Measurement: Enables evaluation based on wear length measurement (or potentially mass loss using the integrated balance).
Suitable for Soles and Materials: Applicable for testing both finished soles and samples of sole materials.
Includes Integrated Balance: The presence of a balance facilitates wear assessment by mass loss if required by the test method or user preference.
Product Features:
Rotary grinding head with a specified grinding wheel.
Mechanism for applying a vertical load (pressure) to the sample via the grinding head.
Sample holder to securely position the sole or sole piece for testing.
Motor and control system to rotate the grinding wheel at a controlled speed (191 ± 5 r/min, adjustable).
Timer to control the duration of the test (20 minutes, adjustable).
Detailed specifications for the grinding wheel, ensuring a standardized abrasive surface.
Integrated balance for weighing samples (5000g range, 0.5g accuracy).
Likely includes a counter to track the number of rotations.
Designed for operation within specific temperature and humidity ranges.
Robust construction suitable for repeated use in a laboratory or quality control environment.
Method for measuring wear length (as mentioned in the introduction) - this could be a manual measurement using a scale after the test or an integrated measurement system, although not explicitly detailed.
Technical specifications:
Performance: Accurate weighing, stability, good repeatability, the use of environmental requirements: at a specific temperature (23±2℃)， measuring the weight of the material and water
Speed: (191±5)r/min(adjustable)
Load: 500g(5g-500g optional)
