Overview
PUYUN PY-H602 computerized paper bursting resistance tester, also known as fatigue folding resistance tester, is a professional equipment used to detect the number of folding times and folding resistance of paper. The instrument is mainly used to evaluate the folding fatigue resistance of various types of paper such as box Cardboard, kraft paper, cardboard, corrugated paper, gray board paper, etc. It is suitable for paper production enterprises, Cardboard carton production enterprises, mass supervision institutions and scientific research institutions and other fields.
Features
The folding angle is infinitely adjustable, ranging from 0 ° to 142 °.
The folding speed can be adjusted arbitrarily, ranging from 10 times/minute to 2000 times/minute.
3. Using imported tension configuration, Tension Stability is significantly improved compared with Chinese brands.
4. Equipped with a 5-inch LCD screen, it can display test data in real time.
5. Integrated modular integrated thermal printer, easy data output.
6. The lower fixture adopts the cylindrical knurled knob clamping method, which is more convenient to be clamped by force.
Principle
The instrument works according to the principle of MIT folding resistance method. The specimen is held under adjustable spring tension, and the specimen is repeatedly bent by a folding head with adjustable speed and angle until the specimen breaks. The instrument automatically records and displays the number of folding times before breaking to evaluate the fatigue performance of the paper.
Applications
Paper production enterprises, Cardboard box production enterprises, mass supervision bureau, scientific research institutions
Standards
GBT 2679.5 paper and Cardboard - Determination of folding resistance (MIT folding method), ISO 5626 paper - Determination of folding resistance
Steps
1. According to the test requirements, set the appropriate folding angle, speed, spring tension and gap distance of the folding opening.
2. Hold the specimen with a length of not less than 140mm between the upper and lower clamps as required.
3. Start the instrument and start the folding test.
4. The instrument automatically records the number of folds when the sample breaks, and displays it in real time on the screen.
5. After the test is completed, the test data can be output through the integrated thermal printer.
Notice
* Please ensure that the working environment temperature is between 0 and 35 ° C and the humidity is lower than 85%.
* Power supply voltage AC220V, 50Hz before use.
According to the test standards and requirements, correctly select and configure the distance between the cracks of the folding mouth (0.25mm, 0.5mm, 0.75mm or 1.00mm).
When clamping the sample, ensure that the lower clamp is firmly clamped through the cylindrical knurled knob to ensure stable force during the test.
During the operation of the instrument, do not touch the folding head and moving parts.
Regular maintenance and calibrating to ensure the accuracy of test results.
