s2: dripping 1mL of 80 ℃ hot water into the center of the corrugated paper sample by using a 1mL syringe, and starting timing;
s3: when the front edge of the corrugated paper sample is completely diffused by water, recording time T1; when the back of the corrugated paper sample under the flat mirror is soaked, the time T2 is recorded.
The corrugated paper sample is 1/100 square meter quantitative tablets.
The corrugated paper sample can be placed a plurality of times.
Compared with the prior art, the invention has the beneficial effects that:
the invention relates to a device for detecting the moisture regain resistance of corrugated paper, which observes the water drop diffusion condition of the top surface of a corrugated paper sample through a high power magnifier and observes the permeation condition of the back surface of the corrugated paper sample through a plane mirror, thereby recording the time for the water drop to be completely diffused and the time for the water drop to permeate, taking the two times as indexes for measuring the moisture regain resistance of paper, and the longer the diffusion time and the permeation time of the paper are, the stronger the moisture regain resistance is.

Detailed Description
The invention is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.
As shown in fig. 1, the device for detecting the moisture regain resistance of corrugated paper provided by the invention comprises a frame body 1, wherein the frame body comprises a vertical rod and a supporting part at the bottom, the vertical rod is used as an installation part of each part, and the supporting part can be a supporting disc, a supporting leg and other structures. The utility model discloses a corrugated paper sample, including support body 2, transparent platform 4, transparent platform 2, transparent platform 4, transparent platform 2, high magnifying glass, transparent platform 2, transparent platform bottom portion is subsided to the level setting. When the corrugated paper sample is placed on the transparent setting table, the high power magnifier is used for observing the liquid diffusion condition of the top surface of the corrugated paper sample, and the plane mirror is used for observing the permeation condition of the back surface of the corrugated paper. Through the high power magnifying glass, the condition that the observation sample top surface was diffused completely that can be more accurate to note the diffusion and need use the time completely, can compromise through the reflection of level crossing and observe the condition that the sample back was soaked, can take notes two time index through a test, make the detection efficiency of corrugated paper higher.
Concretely, all set up adjustable ring 5 between transparent arrangement platform 2, high power magnifying glass 3 and level crossing 4 and the support body 1, adjustable ring 5 and support body 1 sliding connection, set up knob 6 on the adjustable ring 5, knob 6 is used for fixing adjustable ring 5 and support body 1. Through the adjustable ring slides on the montant of support body, can adjust and make transparent arrangement platform 2, high power magnifying glass 3 and level crossing 4 between keep suitable distance to make things convenient for operating personnel to the observation of the square two sides of corrugated paper, the knob is through the screw thread fit fastening on with the adjustable ring promptly, fixes the adjustable ring on the support body.
Specifically, the transparent mounting table 2 is a glass plate. The glass plate has excellent light transmission performance, and can ensure that the back of the corrugated paper sample is clearly soaked under the reflection of the plane mirror.
