Problems solved by technology

For example, lint and powder loss of printing paper will change the printing quality drastically, resulting in unclear printed matter; lint and powder loss of household paper will leave scratches, seriously affecting the user experience... Filter rod forming paper, food packaging paper, stainless steel Lining paper and almost all kinds of paper lose hair and powder will affect the use effect
At present, there is no good method to quantitatively evaluate the lint and powder loss of paper, which makes it impossible to effectively improve the process and improve product quality for the problem of lint and powder loss in production.

Embodiment

[0016] In an implementation case, take 2 paper samples, take 3 sheets of paper for each paper sample, take a strip of paper with a width of 15mm and a length of 200mm from the middle position of each sheet, and fix its two ends on a thin plate, using 15mm The wide black PVC tape sticks the paper strip lightly to ensure that the tape and the paper strip fit smoothly, and cut the tape-bonded paper strip into a length of 180mm.

[0017] Use a stainless steel block with a mass of 250g and a size of 180mmx15mm to completely cover the tape surface and press it for 10 seconds.

[0018] Peel off the tape from the sample by hand and mark the end of the strip. Fix the two ends of the separated tape and the sample on the two ends of the tensile tester, select the peeling mode, and at a constant speed, keep the tape and the sample at a 180° separation angle to peel off, set the measuring range to 80mm, and the tensile speed to 400mm / m i n.

[0019] Cut off the part that was peeled off ...

Abstract

The invention relates to a method for detecting lint and powder falling amount of paper. According to the method, paper lint and paper powder with low bonding strength are adhered down by using the adhesive force of an adhesive tape; the pressure of a stainless steel block with the mass of 250 g and the size of 180 mm * 15 mm is used for providing consistent pressure for the sample; a tension meter is used for stripping, so that stable stripping force is ensured; and analyzing a statistical result by utilizing Image J image processing software.

Description

technical field [0001] The invention relates to a method for detecting paper, in particular to a method for detecting the amount of lint and powder on paper. Background technique [0002] The problem of paper linting and powdering has a detrimental effect on paper for various purposes. For example, lint and powder loss of printing paper will change the printing quality drastically, resulting in unclear printed matter; lint and powder loss of household paper will leave scratches, seriously affecting the user experience... Filter rod forming paper, food packaging paper, stainless steel Lining paper and almost all kinds of paper lose hair and powder, which will affect the use effect. At present, there is no good method to quantitatively evaluate the lint and powder loss of paper, which makes it impossible to effectively improve the process and improve product quality for the problem of lint and powder loss in production. Therefore, it is particularly critical to find a quanti...
