Problems solved by technology

For paper printed with ink, folding endurance testers, creasing machines, and ovens are usually used to judge the folding endurance and moisture content of various brands of base paper. This is a routine detection method for practitioners in paper-related industries, but only through paper folding And water content to judge, is unable to represent the printing adaptability of the paper as a whole
Although the current Kebo absorbency tester can distinguish the good and bad of pap

Embodiment 1

[0067] Drop a drop of 0.05mL povidone-iodine solution at a height of 30cm on the A4 size Asian pulp-coated white cardboard, and start timing when the solution falls on the paper. After a time interval of 10 seconds, quickly take pictures of the solution on the Asian pulp paper According to the apparent diffusion and absorption on the surface, continue to add the solution dropwise. After the solution cannot be completely absorbed, absorb the solution with absorbent paper, weigh its weight and calculate the weight increase before and after, and repeat this operation on three white cardboards.

[0068] Such as figure 2 As shown, the comprehensive results show that on the Asian pulp white cardboard, the droplets spread into a regular circle, the entire circular area is dark yellow, and there are very few black spots. Among the six example papers, the absorption is the best, and the records before and after the test .

Embodiment 2

[0070] Drop a drop of 0.05mL povidone-iodine solution on the A4 size Golden Sun coated white cardboard at a height of 30cm, and start timing when the solution falls on the paper. According to the apparent diffusion and absorption on the surface, continue to add the solution dropwise. After the solution cannot be completely absorbed, absorb the solution with absorbent paper, weigh its weight and calculate the weight increase before and after, and repeat this operation on three white cardboards.

[0071] Such as image 3 As shown, the comprehensive results show that on the Golden Sun white cardboard, the droplets spread into a relatively regular circle, and the entire circular area is dark yellow, with a few black spots, which are slightly more than Asian pulp.

Embodiment 3

[0073] Drop a drop of 0.05mL povidone-iodine solution at a height of 30cm on the A4 size Hongta coated white cardboard, and start timing when the solution falls on the paper. According to the apparent diffusion and absorption, continue to add the solution dropwise. After the solution cannot be completely absorbed, absorb the solution with absorbent paper, weigh its weight and calculate the weight increase before and after, and repeat this operation on three white cardboards.

[0074] Such as Figure 4 As shown, the comprehensive results show that on the Hongta white cardboard, the droplets spread into a regular circle, and the entire circular area is dark yellow, and there are thick black areas in it, which are more than the golden sun.

Abstract

The invention discloses a paper absorption comprehensive performance testing method which is characterized by comprising the following steps of fixing a burette filled with a povidone-iodine solution on a workbench, vertically dropping a certain amount of povidone-iodine solution at a fixed height, dropping the povidone-iodine solution onto to-be-detected paper placed on the workbench, shooting and recording the apparent diffusion absorption conditions of the povidone-iodine solution droplets of all brands of paper at the same time interval, after complete absorption, dropping a certain amount of solution at the same position until complete absorption is not achieved, sucking away the surface solution with absorbent paper, weighing the increased weight, and achieving comprehensive performance testing. The reddish-brown povidone-iodine solution is adopted, so that the apparent absorption and diffusion conditions of the solution on the paper can be more easily and visually sensed, the absorption uniformity is quickly reflected and serves as the most important performance index, and the absorption performance of the paper is comprehensively considered from the aspects of the absorption uniformity, the absorption rate, the absorption multiplying power and the like.

Description

technical field [0001] The invention belongs to the field of testing the absorption performance of paper, especially cigarette pack paper, and in particular relates to a method for testing the comprehensive absorption performance of paper, a tester and an application thereof. Background technique [0002] The water absorption of paper depends on the properties of fibers, the beating degree of pulp and the structure of paper. At the same time, in the process of paper production and processing, due to the influence of many factors such as raw materials, auxiliary materials, equipment, processes and operation methods of various manufacturers, it will also cause Different brands of paper have different performance characteristics such as absorbency, folding resistance, smoothness, and moisture content. These performance characteristics directly affect the printing adaptability of the paper. The paper with poor adaptability is prone to ink explosion after ink printing, that is, t...
