Technical Parameters

Accessoriess

The accessories of a multi-functional scratch tester mainly include the following, with brief descriptions of their functions:

Scratching Head/Probe: Scratching heads of different materials (e.g., steel, ceramic, plastic) and shapes (e.g., spherical, conical) are used to simulate the scratching of material surfaces by objects of different hardness and shapes, evaluating the material's wear resistance and scratch resistance.

Weights/Load Device: Adjusts the pressure applied to the scratching head to simulate the scratching force under different usage scenarios, ensuring controllable and repeatable test conditions.

Sample Fixture: Securely fixes the test sample, preventing movement or deformation during scratching and ensuring the accuracy of test results.

Moving Platform/Guide Rail: Controls the movement path and speed of the scratching head, enabling scratching tests on straight lines, curves, or specific patterns to meet diverse testing needs.

Measurement System (e.g., Sensors): Monitors and records parameters such as force and displacement during the scratching process in real time, providing a basis for data analysis.

Control Panel/Software: Sets test parameters (e.g., scratching speed, pressure, path), starts/stops the test, processes and stores test data, and generates test reports.

Test Procedures

The operation method of the multi-functional scratch tester includes preparation, parameter setting and sample installation, test start, test termination and data processing, cleaning and maintenance, and precautions. In actual operation, appropriate adjustments should be made according to the specific instrument model and test requirements. The following are some general operating steps:

Prepare Accessories and Test Samples: Prepare all accessories for the multi-functional scratch tester (such as weights, scratch heads, clamps, etc.). Prepare the corresponding test samples according to the test requirements, ensuring they are flat, clean, and stably fixed.

Check Instrument Status: Ensure the multi-functional scratch tester is in good working order, including checking the power supply, display screen, and transmission system for proper function. Check that the scratch head and clamps are securely installed to avoid damage.

Set Parameters: Adjust the scratching speed, load value, and other relevant parameters according to specific test requirements.

Install Scraping Tool: Select the appropriate scratch needle or head and correctly install it onto the test head.

Start Test: Start the instrument and allow the scratching tool to scrape the sample surface according to the set path.

End of Test: After testing, analyze and compare the samples to assess the material's surface scratch resistance and durability.

Data Processing: Record any visible changes or damage, and perform detailed analysis using a microscope or other auxiliary tools if necessary.

Cleaning and Maintenance: Clean the instrument regularly to maintain its normal operating condition.

Precautions: During testing, pay attention to the flatness and stability of the samples, and avoid damaging the samples with scratching tools.
