Problems solved by technology
At present, the detection of corrugated base paper is mainly to detect the surface absorbency and ring crush strength of the finished paper, and the surface absorbency test of the paper is mainly to detect the ink absorption capacity of the paper, so the single surface absorbency test cannot accurately detect Moisture resistance of paper

Embodiment
[0029] Select three batches of corrugated base paper. The thickness of batch 1 is 220 μm, the thickness of batch 2 is 210 μm, and the thickness of batch 3 is 230 μm. Cut the three batches of corrugated paper into two pieces with a diameter of 11.3 cm. 2 Place two corrugated paper samples of each batch on the transparent placement table, adjust the distance between the transparent placement table on the frame body and the high-power magnifying glass and plane mirror through the cooperation of the adjustment ring and the knob, so that The image of the corrugated paper sample under a high-power magnifying glass is clear; make the image of the corrugated paper sample reflected by the plane mirror clear; use a 1mL syringe to add 1mL of 80°C hot water to the center of the corrugated paper sample, and start timing; when the front edge of the corrugated paper sample is completely diffused by water , record the time T1; when the back of the corrugated paper sample reflected by the plane...

The invention provides a device and method for detecting anti-moisture regain performance of corrugated paper, and mainly designs the field of corrugated paper performance detection. The device for detecting anti-moisture regain performance of corrugated paper comprises a frame body, wherein the frame body is provided with a transparent placement table for carrying corrugated paper samples, a highmagnifying glass is disposed on the frame body above the transparent placement table, a flat mirror is set below the transparent placement table, and the transparent placement table, high magnifyingglass and flat mirror are all horizontally arranged. The device and method for detecting anti-moisture regain performance of corrugated paper provided by the invention have the beneficial effect of being able to intuitively express its anti-moisture regain performance through the soaking time and diffusion time of the corrugated base paper.
Description
technical field [0001] The invention mainly relates to the field of performance detection of corrugated paper, in particular to a device and method for detecting the anti-moisture performance of corrugated paper. Background technique [0002] Corrugated base paper is mainly used in the production of packaging boxes, and is more and more widely used in the production of refrigerated packaging boxes. The refrigerated packaging boxes must have strong ring compression strength to avoid collapse after moisture absorption. At present, the detection of corrugated base paper is mainly to detect the surface absorbency and ring crush strength of the finished paper, while the surface absorbency test of the paper is mainly to detect the ink absorption capacity of the paper, so the single surface absorbency test cannot accurately detect Moisture resistance of paper. Therefore, we only make this type of equipment, and use the constant moisture soaking and diffusion time of the paper as a...
