Introduction to the Paperboard Folding Resistance Tester
The Paperboard Folding Resistance Tester is a vital instrument engineered for evaluating the fold endurance performance of sheet materials, including paper, cardboard, and tobacco sheets, with a thickness of less than 1.25 mm. This robust device ensures precise assessment under controlled conditions, providing invaluable data for industries reliant on material durability.
In operation, specimens undergo double folding to measure their resistance to folding stresses. The tester calculates the logarithmic value (base 10) of the number of double folds until the specimen fractures. This measurement, known as fold endurance, is crucial for determining how well materials can withstand bending without sustaining damage. Generally, higher fold endurance values suggest enhanced durability and resistance to stress, making the Paperboard Folding Resistance Tester essential for manufacturers and researchers.
Industries such as paper production, cardboard manufacturing, and tobacco processing benefit significantly from this testing, as it helps in evaluating how materials can perform under realistic usage scenarios. This understanding aids in selecting and improving materials based on performance characteristics, ensuring the highest quality in end products.
Technical Features
- Adjustable Folding Rate: Ranges from 20 to 200 double folds per minute, allowing for versatile testing conditions.
- Variety of Tension Weights: Accommodates various material types.
- Color Touchscreen Operation: User-friendly interface for ease of use.
- Multiple Folding Heads: Suitable for a wide range of sample sizes and types.
- Embedded Micro Printer: Automatically records test results for convenience.
Test Principle of the Paperboard Folding Resistance Tester
To initiate testing with the Paperboard Folding Resistance Tester, level the instrument and align the oscillating folding head vertically. Apply the desired tension weight (typically 9.81 N) and ensure the test specimen is firmly clamped in place. As folding commences, the tester counts the number of double folds until the specimen breaks, allowing for the precise calculation of fold endurance.
Standards Compliance
The Paperboard Folding Resistance Tester complies with several international standards, including:
- ISO 5626
- TAPPI T511
- GB/T 457
- QB/T 1049
This compliance ensures that your testing results are reliable and recognized across industries.
