Overview
The LD-SL-B Tear strength tester is a fully automatic intelligent testing instrument of the JINGHUAYIQI brand, specially designed for automation technology to detect the tear resistance of materials. The instrument is suitable for the determination of Tear strength of paper, film, Spinning & weaving products, Rubber & plastics sheet materials, etc. It is a measurement tool required by paper production enterprises, paper chemical enterprises, Encasement production enterprises and mass inspection departments.
Features
1. One-button intelligent operation, instant measurement of paper Tear Strength and tear index.
2. Adopt large-screen high-pixel 3.2-inch LCD display, Chinese display and prompt operation steps, display measurement and statistical results, friendly man-machine interface makes the instrument operation simple and convenient.
3. The instrument adds a printer and adopts an imported thermal printing movement, which does not require the use of inks and color ribbons, works without noise, and prints quickly.
Principle
Based on the Ailimendorf method, the tearing strength of a material is automatically measured by parameters such as the tearing arm, the tearing initial angle, and the distance between the clamps. The user can complete the tearing process and calculate the Tear Strength and Tear Index with just one click.
Applications
Paper production enterprises, Paper chemical enterprises, Encasement production enterprises, mass testing departments
Standards
ISO1974、TAPPI 414、GB/T455、QB/T 1050、ISO6383/2-1983、GB11999-89
Steps
1. Prepare samples and ensure compliance with standard requirements.
2. Place the specimen in the paper holder and clamp it manually.
3. Start the intelligent operation with one button, and the instrument automatically performs the tear test.
4. The instrument displays measurement results and statistical information through the LCD screen.
5. Use the thermal printer to output the test report.
Notice
• Operating Conditions: Temperature range 0~ 35 ℃, Humidity < 85%.
Make sure the power supply is AC 220V/50Hz.
• The incision length of the sample should be controlled at 20 +/- 0.5mm.
• Parameters such as tearing arm and tearing initial angle must strictly meet the specifications.
• Check whether the fixture is firm before use to avoid test errors.
