WTD-01 Bending Stiffness Tester For Paper Bending Resistance
Strength Testing Instrument For Paperboard With Touchscreen
Introduction
The WTD-01 Bending Stiffness Tester is an advanced instrument designed specifically for measuring the
bending resistance of paper and board materials. Utilizing a
sophisticated two-point loading principle, this Bending Stiffness Tester is capable of accurately assessing bending resistance within a
range of 20 mN to 10,000 mN. While it is not suitable for
corrugated board, it excels in testing components of such
materials, making it a versatile tool in various industries.
Why You Need a Bending Stiffness Tester
Bending stiffness is a critical property for materials used in
packaging, printing, and other applications where maintaining
structural integrity is paramount. A reliable Bending Stiffness Tester provides essential insights into the material's resistance to
bending and deformation, ensuring that products maintain their
shape and perform effectively under stress. Enhanced bending
stiffness leads to improved rigidity and stability, crucial for
applications in packaging and paper-based products.
Technical Features
- Multi-Angle Measurement: The WTD-01 allows for the simultaneous setup of up to three test
angles, with commonly used angles including 7.5°, 15°, and 30°.
- Customizable Bending Time: Users can select different bending times tailored to the
material's elasticity, ensuring precise measurements.
- User-Friendly Interface: The tester features a 7-inch touchscreen interface, simplifying
operation with a visual menu for enhanced usability.
- Integrated Print Output: Equipped with a modular integrated thermal printer, the WTD-01
enables quick and easy printing of test results for efficient
documentation.
Test Principle
The Bending Stiffness Tester measures the force required to bend a test piece, clamped at one
end, through a specified angle—typically 15°. The bending force is
applied at predetermined bending lengths (either 50 mm or 10 mm),
and the bending resistance is calculated as the average of the
measured forces. This ensures accurate and repeatable results,
essential for quality control and research purposes.
Applications
- Packaging: Bending stiffness plays a vital role in ensuring that packaging
materials retain their shape, providing adequate protection for
contents during transport and handling.
- Printing: In high-speed printing applications, paper with appropriate
bending stiffness is crucial to prevent operational issues, such as
paper jams, enhancing overall efficiency.
- Paperboard Products: Products such as cartons and display boards benefit significantly
from sufficient bending stiffness, contributing to their structural
integrity and performance.
