Technical Field
The invention relates to the technical field of dialysis inspection of fiber and dust of a pulp board, in particular to a dialysis inspection method of fiber and dust of the pulp board.
Background
Along with the improvement of living standard of people, the requirements of people on commodity package are higher and higher, people not only require that the package is firm, but also print related information of various contents and related exquisite pictures on an outer package, therefore, high cleanliness of paper surface often brings better printing and appearance effects, and therefore ultra-clean dust-free paper is always a research and development problem in the industry. Here, the ultra-clean dust-free paper or the dust-free paper means paper having high cleanliness of a paper surface without affecting printing and appearance effects, or being satisfactory for a manufactured paper without affecting visual effects of the paper surface, and does not mean paper completely free of dust.
However, when producing paper, it is difficult to ensure the cleanliness of paper and to control the occurrence of dust on the paper surface because it is impossible to ensure that the production environment is always in a dust-free environment.
Therefore, the method for the dialysis inspection of the fiber dust of the pulp board is provided, the defects in the conventional dust degree detection are overcome, and the quality control is facilitated.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a method for dialyzing and inspecting pulp board fiber dust, which comprises the following steps:
step 1: placing a sample plate on a pulp board fiber dust dialyzer, checking visible dust on the surface of the sample plate under a fluorescent lamp, measuring dust with different areas by using different color marks, determining the area size of different color marks by using a standard comparison graph, and respectively recording the number of dust blocks with the same area;
step 2: rotating the sample plate for four times at 90 degrees, marking the found dark spots or dust after rotating once, and turning back to the initial position;
and step 3: and (3) starting the pulp board fiber dust dialyzer according to the permeability of the material, preferably, the light of the dialyzer penetrates through the sample to appear a shadow visually, repeating the steps 1 and 2, and marking on the single surface by using a pen different from the surface dust marking color.
And 4, step 4: recording the abnormity found by the mark by using a standard comparison graph, breaking the surface layer by using a small blade, and checking the property of the foreign matter;
and 5: using the formula: count = total of unit area of dust/total area of test sample, count result was obtained, and the obtained count result was compared with standard requirement.
Preferably, the number of the test boards in the step 1 is at least 6, the test is directly carried out according to the size of the material to be tested, the size of each test sample is recorded, and finally, the square meter content calculation is carried out.
Preferably, the dust on the surface of the sample plate is inspected under a fluorescent lamp in the step 1, and the visual distance between eyes and the sample is kept between 250mm and 300 mm.
Preferably, when the sample plate in the step 2 is used on both sides, the other side of the sample plate is inspected by the method of the above steps 1 and 2.
Preferably, the standard requirements in step 5 are:
(1) dust area of single mark is less than 5 mm;
(2) acceptable counting result range is less than or equal to 30 mm/m.
Compared with the prior art, the invention has the beneficial effects that: the invention can extract, analyze and judge the foreign matters and impurities in the test board, can visually classify, count and calculate the dust and impurities in the pulp board, makes up the defects in the conventional dust degree detection execution, and is more beneficial to quality control.
