Paper folding resistance tester NZD-2

Product Model: NZD-2

Basic application scope: This instrument is designed according to the Chinese national standard GB/T2679.5 "Determination of Folding Resistance of Paper and Paperboard". It is an opto mechatronic integrated structure that can automatically count the number of double folds of the tested sample.It is specifically designed to measure thickness1mmSpecial instruments for the folding fatigue strength of paper, cardboard, and other sheet materials (such as copper foil in the electronics industry).It is an ideal testing equipment for industries and departments such as papermaking, packaging, scientific research, and product quality supervision and inspection.

Product Features:

The instrument adopts photoelectric control technology, which enables the folding chuck to automatically return to its original position after each experiment, facilitating the next operation. The instrument has powerful data processing capabilities: it can not only convert the number of folds and corresponding logarithmic values of a single sample, but also collect experimental data from multiple samples in the same group. It can calculate the larger, smaller, average, and coefficient of variation of samples in the same group, which are stored in a microcomputer and displayed through a digital tube. In addition, the instrument also has a printing function.

Technical Indicators:

1. Measurement range: ≤ 1 mm;

2. Counting range: 0-9999 times;

3. Folding angle: 135 ± 2 °;

4. Folding speed 175 ± 10 times/min;

5. The width of the folding head is 19 ± 1mm, and the radius of the fold is 0.38 ± 0.02mm;

6. The spring tension is 4.91-14.72N, and for every 9.81N tension applied, the spring compresses by at least 17mm;

7. The distance between the folding seams is 0.25, 0.50, 0.75, and 1.00mm;
