Folding Endurance Tester For Board Paper

Introduction to the NZD-01 MIT Folding Endurance Tester

The Folding Endurance Tester For Board Paper, model NZD-01 MIT, is a cutting-edge instrument specifically designed to evaluate the fold endurance performance of sheet materials, including paper, cardboard, and tobacco sheets, with a thickness of less than 1.25 mm. This tester plays a vital role in the quality control processes of various industries by measuring the durability of materials subjected to bending and folding stresses.

During the testing process, specimens undergo double folding under standardized tension conditions. The logarithm (base 10) of the number of double folds at the point of specimen fracture is meticulously recorded. This logarithmic value, referred to as fold endurance, is a critical metric that indicates a material's resistance to damage caused by folding. Higher fold endurance values typically correlate with greater durability and resilience to folding stress, making the Folding Endurance Tester For Board Paper an essential tool for manufacturers.

Industries that benefit from this testing include paper production, cardboard manufacturing, and the tobacco sector. By utilizing the Folding Endurance Tester For Board Paper, manufacturers and researchers can make informed decisions regarding material selection and improvements based on empirical performance data. This capability is crucial for ensuring that products meet the rigorous demands of their intended applications.

Technical Features

• Adjustable Folding Rate: 20 to 200 double folds per minute, allowing customization based on testing requirements.
• Various Tension Weights: Options to suit different material specifications.
• Color Touchscreen Operation: Intuitive interface for easy navigation and operation.
• Multiple Folding Heads: Designed to accommodate a wide range of sample types.
• Micro Printer Embedded: Provides immediate test results and documentation.

Test Principle

To operate the Folding Endurance Tester For Board Paper, begin by leveling the instrument and adjusting the oscillating folding head to a vertical position. Place a specified weight on the plunger, typically 9.81 N, to achieve the desired tension on the specimen. The next steps include:

1. Securing the test piece in the jaws while ensuring it lies flat and is free from obstructions.
2. Removing the weight to apply the designated tension to the sample.
3. Initiating the folding process and monitoring until the test piece fractures.
4. The counter will automatically stop upon failure, allowing the user to record the number of double folds endured before breakage.

This methodical approach ensures accurate and reliable test results.
