Cardboard Dust Tester - Technical Literature

Cardboard Dust Tester - Technical Literature Jinan Sanquan Zhongshi Experimental Instrument Production Of Dust Detector, with an instrument that can detect the dustiness of paper, cardboard and pulp, has the advantages
of simple operation and intuitive result display.

So what is the degree of dust, and what impact will the degree of dust have on people's use, let's take a look at the next one
.

To understand the degree of dust, it is necessary to understand what impurities are, which are any unwanted small piece of substance embedded in the pulp, whose size exceeds the specified minimum size and shows obvious opacity
relative to the surface of the paper.

The degree of dust is the number of impurities with a certain area of impurities per square meter of paper, or the equivalent area of paper impurities per square meter of paper
.

Then some people will say that the degree of dust will not affect the use, why test? We take printing paper as an example, dusty paper, especially black dust paper, will form a stain on the printing graphics, easy to punctuation and numbers and other fine line errors, even if it does not cause errors or become waste, more dust will also bring inconvenience
to reading.
