Overview
LD-NHJ-01 adhesive strength fixture is a professional test fixture of JINGHUAYIQI brand, mainly used to test the adhesive strength of various types of Corrugated Board. The fixture needs to be used with Ring Crush Test Machine and Vertical Pressure and Adhesive Strength Test Sampler, and the sample size is 25 +/- 0.5 × 80 +/- 0.5mm.
Features
1. Designed for Corrugated Board adhesive strength testing
2. Provide a variety of steel needle sizes to adapt to different corrugated types
3. Use with standard test equipment
4. The optional configuration is flexible, and the φ 1.0mm steel needle can be selected according to the test requirements
Principle
The clamp is inserted into the Corrugated Board sample through a steel needle of a specific size, and pressure is applied under the cooperation of the Ring Crush Test machine to measure the adhesive strength between the layers of the Corrugated Board. Different corrugated boards correspond to different needle sizes and pitch settings.
Applications
Corrugated Board adhesive strength test
Standards
GB/T6548、ASTM D918、CNS3327
Steps
1. Select the corresponding steel needle size and needle spacing according to the Corrugated Board
2. Prepare 25 +/- 0.5 × 80 +/- 0.5mm specimens
3. Connect the fixture to the Ring Crushing Test Machine
4. Place the specimen correctly on the fixture
5. Start the testing machine for testing
Step 6 Record test results
Notice
• When testing the E Corrugated Cardboard, you need to buy a φ 1.0mm steel needle configuration
• Specimen size must be strictly controlled within the range of 25 +/- 0.5 × 80 +/- 0.5mm
• Different corrugated types need to use the correct steel needle size and needle spacing
• Ensure that the fixture is properly connected to the testing machine
• Check whether the steel needle is intact and nondestructive before testing
