Overview
JINGWEN JW-114-1 Pitch Paper cutter is a paper production instrument, developed and produced in accordance with the relevant requirements of the national standard GB/T 12914-1991 "Paper and Cardboard Tensile Strength Determination Method (Constant Speed Tension Method) ", used to detect the tension of paper, Tensile Strength, elongation, fracture length, Tensile Energy Absorption, tensile index, Tensile Energy Absorption index, etc., and can also be used for other sheet materials. Tension, elongation, fracture length, tensile index, etc.
Features
1. Wide sampling size range: length ≤ 300mm, width ≤ 320mm.
2. High Accuracy sampling: small sampling size error, such as 15mm +/- 0.10mm, 38mm +/- 0.20mm, 63mm +/- 0.30mm, Miscellaneous size +/- 0.50mm.
3. High parallelism of incision: ≤ 0.1mm.
4. Strong adaptability of sampling thickness: < 1.0mm.
5. Compact design: Dimension 560 * 400 * 160mm, weight about 15kg.
Principle
The instrument cuts paper or sheet materials at a fixed distance, preparing standard samples for subsequent tensile performance testing to ensure that the sample size and incision accuracy meet the relevant standard requirements to accurately determine the material's Tensile Strength and other mechanical properties.
Applications
Paper testing equipment, paper production equipment, sheet material tensile test
Standards
GB/T 12914 "Determination of Paper and Cardboard Tensile Strength (Constant Tensile Method) ", GB/T 12914 "Determination of Paper and Cardboard Tensile Strength", ISO 1924.2 "Determination of Paper and Cardboard Tensile Strength: Constant Tensile Method", GB13022 "Plastic film tensile performance test method", GB/T 1040 "Plastic tensile performance test method", GB/T 14344 "Chemical fiber filament tensile performance test method"
Steps
1. Prepare paper or sheet materials.
2. Set the sampling size according to the test requirements (length ≤ 300mm, width ≤ 320mm).
3. Use the instrument for fixed-distance cutting to ensure that the parallelism of the incision is less than or equal to 0.1mm.
4. Check whether the sampling size error meets the standard requirements.
5. Use the cut specimen for subsequent tensile performance testing.
Notice
• The sampling thickness should be less than 1.0mm.
• The sampling size error should be controlled within the standard range (e.g. +/- 0.10mm at 15mm).
• Ensure that the notch parallelism is less than or equal to 0.1mm to improve Test accuracy.
• Pay attention to safety during operation to avoid cutting injuries.
Periodically calibrate instruments to ensure measurement accuracy.
