Overview
Microcomputer paper tearing meter BLD-SL17 is an instrument for testing the tearing resistance of materials, suitable for testing the tearing strength of paper, film, Spinning & weaving products, Rubber & plastics sheet materials, etc. The instrument is a measurement tool for paper manufacturers, paper chemical companies, Encasement manufacturers and mass inspection departments.
Features
1. Measurement range: A (50~ 8000) mN, B (8000~ 16000) mN
2. Precise mechanical parameters: tearing arm 104 +/- 1mm, tearing initial angle 27.5 +/- 0.5 °, tearing distance 43 +/- 0.5mm
3. Professional clamping design: the size of the paper clamping surface is 25 * 15mm, and the distance between the paper clamps is 2.8 +/- 0.3mm.
4. Wide environmental adaptability: Operating temperature 0~ 35 ℃, humidity < 85%
Principle
The instrument is based on the principle of the Alimendolf method and measures the tear resistance of materials under specific conditions by precisely controlling the tear arm, initial angle and tear distance.
Applications
Paper production enterprises, Paper chemical enterprises, Encasement production enterprises, mass testing departments
Standards
GB/T 455 "Paper and Cardboard Tear Degree", ISO 1974 "Paper - Tear Degree Determination (Alimendorf Method) ", QB/T 1050 "Paper and Cardboard Tear Degree Meter"
