Overview
The IMT-IGTA1 printing surface strength tester is a special instrument for detecting the surface strength of Spreader paper and non-Spreader paper. The instrument is an important physical indicator reflecting the adaptability performance of paper printing and is a common equipment used to control Printability performance in paper mills, printing mills and inks mills.
Features
The test area is accurate, 10 +/- 0.05cm.
2. Measurement range, covering (0.2~ 3.5) m/s.
3. The proofing pressure can be adjusted from 0 to 700N.
4. Provide a variety of specifications of printing disc (φ 65 × 10mm, φ 65 × 20mm) and rubber pad, paper pad accessories.
Principle
The instrument uses the pendulum to move at a specific elevation angle and speed to drive the printing disc to apply adjustable pressure to the paper sample for proofing. Basis Weight evaluates the printing surface strength by measuring the disbonding or damage strength of the paper surface under specific conditions.
Applications
Paper mills, printing mills, inks mills
Standards
GB/T 22365-2008、GB/T2679、ISO 3782、QB/T 1020
Steps
1. Select and install the appropriate printing disc (φ 65 × 10mm or φ 65 × 20mm) according to the test requirements.
2. Prepare and install the corresponding rubber pad (320 x 35 x 1.5mm) or paper pad (305 x 35 x 1.5mm).
3. Place the paper sample in the test position.
4. Adjust the proofing pressure to the required value (within the range of 0 to 700 N).
Set the pendulum elevation to 165 degrees.
6. Start the instrument and move the pendulum at the set speed (20 to 125 cm/s) for proofing.
7. Record the measurement results. Precision is 0.1 s.
Notice
• Please ensure that the instrument is placed horizontally before use.
• Select the correct printing tray, rubber pad or paper pad according to the test criteria.
The proofing pressure needs to be accurately set within the instrument range (0~ 700N).
• Measuring accuracy by calibrating instruments regularly.
• Please pay attention to safety during operation and avoid touching the test area when the pendulum is moving.
• Keep instruments and accessories clean to avoid contaminating samples.
