Schopper Folding Endurance Tester
Use and Scope of application:
1. the instrument is suitable for tensile strength greater than 1.33kn/m, thickness less than 0.25mm paper folding determination.
2. the instrument structure parameters and technical performance are in line with GB/T457-2008 "Paper folding resistance determination method" and other relevant standards.
Implementation standards:
GB/T457-2008
ISO 5626
Product Advantages:
Measures Key Durability Property: Quantifies folding endurance, a direct measure of a paper's resistance to repeated folding, crucial for many applications.
Standard Compliant (Schopper Method): Operates according to established national and international Schopper folding endurance testing standards.
Quantitative Result: Provides an objective numerical value (number of folds to break) for folding endurance.
Controllable Test Parameters: Allows for setting and maintaining specific test tension and folding rate as required by the standards.
Suitable for Specified Paper Types: Designed to accurately test papers within defined tensile strength and thickness ranges.
Product Features:
Folding head mechanism consisting of two oscillating folding rollers.
Clamping system to hold the paper strip specimen at both ends.
Tensioning mechanism to apply and maintain the specified initial and maximum tensile load on the sample during the test (Initial tension: 7.55 ± 0.10 N, Maximum tension: 9.81 ± 0.10 N).
Counter to record the number of double folds (cycles) the sample withstands before rupture, with a counting range of 0-9999 times.
Reciprocating folding action at a controlled rate (110 ± 10 times/min).
Folding rollers with a specific diameter (6mm).
Precise spacing between the folding roller and the folding roller (0.30mm) and between the folding rollers themselves (0.5mm).
Specific distance between the chucks of the same group (90 ± 0.5mm).
Designed to test paper within a maximum thickness limit (0.25mm).
