Abstract
The invention discloses a method for detecting water absorption of thin paper, which comprises the following steps: s1, cutting thin paper into a square with the side length of more than 5cm as a paper pattern, stacking at least 15 layers; s2, pressing the hollow ring on the stacked paper patterns; it should be noted that the hollow ring can press the stacked paper patterns to a certain tightness, which is convenient for the subsequent steps. S3, absorbing the color developing agent by using a suction pipe, and dripping one drop of the color developing agent to the topmost stacked paper pattern and the center of the hollow ring to the extent that the color developing agent can be just dripped; s4, after dripping is finished, taking away the hollow circle, immediately turning the stacked paper patterns for 180 degrees, and loosening the stacked paper patterns among layers; s5, distinguishing the paper with the penetrated marks from the paper without the penetrated marks; and S6, recording the number of the paper penetrated with the mark to obtain the water absorption parameter of the coated paper. The invention has the advantages of simple method, low cost, convenient detection and good quality control.
Description
Technical Field
The invention relates to a method for detecting water absorption of thin paper.
Background
When the paper is thin, the method for detecting the water absorption by the national standard has small difference of the detected result, but in the actual situation, the water absorption speed of the paper may have very large difference, so the method for detecting the water absorption by the national standard cannot well reflect the water absorption performance of the paper.
Disclosure of Invention
The invention provides a method for detecting water absorption of thin paper according to the defects.
The technical scheme of the invention is as follows:
a method for detecting water absorption of a tissue comprises the following steps:
s1 cutting thin paper into squares with side length more than 5cm as paper patterns, stacking at least 15 layers;
s2, pressing the hollow ring on the stacked paper patterns; it should be noted that the hollow ring can press the stacked paper patterns to a certain tightness, which is convenient for the subsequent steps.
S3, sucking the color developing agent by a suction pipe, and dripping one drop of the color developing agent to the topmost stacked paper pattern and the center of the hollow ring to the extent that the color developing agent can just drip; it is noted that the color developing agent can be easily identified by human eyes;
s4, after the dripping is finished, taking the hollow circle away, immediately turning the stacked paper patterns for 180 degrees, and loosening the stacked paper patterns among layers; it should be noted that this step is mainly to define a reasonable procedure to prevent the result from changing because each action is not uniform. The step can prevent the color developing agent from continuously permeating into the following paper when the number of people is counted, so that the test result is inaccurate.
S5 distinguishing the paper sheet penetrated with the print from the paper sheet not penetrated with the print;
s6 records the number of sheets that have penetrated the print to obtain the water absorption parameter of the coated paper. It should be noted that when the water absorption parameter is greater than or equal to 12 sheets, we set it as the qualified standard.
Preferably, in step S1, the number of layers of the pattern is 20.
Preferably, in step S1, the square has a side length of 5 cm.
Preferably, the color developer is dimethylphenol orange, purple.
Preferably, the hollow ring has an inner diameter of 22mm, an outer diameter of 55mm and a weight of 33 g. It should be noted that, in each detection, the same hollow ring is used to press the paper.
Preferably, the tissue paper comprises coated paper.
The concentration of the color developing agent is 0.5%.
The invention has the advantages of simple method, low cost, convenient detection and good quality control.
Detailed Description
A method for detecting water absorption of a tissue comprises the following steps:
s1 cutting thin paper into squares with the side length of 5cm as paper patterns, stacking at least 20 layers;
s2, pressing the hollow ring with the inner diameter of 22mm, the outer diameter of 55mm and the weight of 33g on the stacked paper patterns;
s3, sucking 0.5% of developer dimethyl phenol orange with purple color by using a suction pipe, and dripping one drop of the developer dimethyl phenol orange into the topmost stacked paper sample at the center of the hollow ring until the developer dimethyl phenol orange can just drip;
s4, after the dripping is finished, taking the hollow circle away, immediately turning the stacked paper patterns for 180 degrees, and loosening the stacked paper patterns among layers;
s5 distinguishing the paper sheet penetrated with the print from the paper sheet not penetrated with the print;
s6 records the number of sheets that have penetrated the print to obtain the water absorption parameter of the coated paper.
The thin paper is coated paper.
