Overview
The paper Tear strength tester JW-111A is a fully automatic testing instrument developed by JINGWEN brand for automation technology, which is used to determine the tear resistance of materials. The instrument is suitable for the detection of Tear strength of paper, film, Spinning & weaving products, Rubber & plastics sheet materials and other materials. It is an ideal measurement tool for paper manufacturers, paper chemical companies, Encasement manufacturers and mass inspection departments.
Features
1. Fully automatic testing equipment to meet the needs of automation technology
2. Measurement range, up to 10~ 16000mN
3. High resolution 0.1mN, Indication Error +/- 1.0%
4. Equipped with pneumatic fixture, easy to operate
5.3.2-Inch LCD display, displaying test data in real time
6. Built-in thermal printer, can directly output test results
Principle
Tearing force is applied to the specimen by the design of specific tearing arm and initial tearing angle. When the specimen is torn, the instrument accurately measures the force required during tearing process to calculate the material's Tear strength.
Applications
Paper production enterprises, Paper chemical enterprises, Encasement production enterprises, mass testing departments
Standards
GB/T 455、ISO 1974、QB/T 1050
Steps
1. Prepare the sample and make incisions as required
2. Load the specimen into the paper holder
3. Start the pneumatic fixture to fix the sample
4. Set test parameters
Step 5 Start testing
6. Read LCD display data
7. Output the result through the thermal printer
Notice
• Ambient Temperature should be kept in the range of 0~ 35 ℃
• relative humidity should be less than 85%
• AC 220V/50Hz power requirements
• Make sure that the cut length of the sample meets the requirements of 20 +/- 0.5mm before testing
• Regularly calibrate instruments to ensure Measurement accuracy
• Pay attention to safety during operation to avoid pinching
