Detailed Description
For a better understanding of the technical content of the invention, specific embodiments are provided below, and the invention is further described with reference to the accompanying drawings.
Example 1
A quantitative detection method for paper folding explosive powder comprises the following steps:
s1: folding the paper 4 to obtain the length of the folding S, and cleaning the paper powder at the folding;
after the paper 4 is bent, a certain pressure is applied to crease the paper 4. Specifically, a hand may be used to press the paper 4, or a weight, such as a weight, an iron block, or the like, may be placed on the paper 4. The crease is removed by a weight of the same weight, 10kg in weight, at each folding. After the paper 4 is folded, the paper 4 is unfolded, and the paper powder falling out from the folded position of the paper 4 is cleaned by a cleaning brush. The length of the fold of the paper 4 can be measured by a length measuring tool, such as a ruler, a tape measure, a caliper, etc., or can be directly obtained without measurement, such as the length of the fold is equal to the length or width of the paper 4, and the length of the fold of the paper 4 is known when the paper 4 leaves the factory, and the length of the fold of the paper 4 can be directly obtained without measurement. Preferably, in the step S1, the length of the fold of the sheet 4 is equal to the length or width of the sheet 4, which is convenient for measurement.
S2: repeating the step S1 n times, wherein the K-th fold length is Sk；
And the step of S1 is repeated, so that more paper powder can be obtained conveniently, and the detection precision can be improved conveniently. It is understood that the position of the folding line may be fixed in each repeated step of S1, or the folding line may be performed at a new position, and the folding line at the new position may be performed at a different position of the same sheet 4, or may be performed by replacing a new sheet 4. If the paper 4 is folded for multiple times at the same position, the powder explosion degree represents the powder explosion degree of the folded paper 4 at the same position for multiple times; if the paper is folded for multiple times at different places, the degree of the powder explosion represents the degree of the powder explosion of the single fold of the paper 4.
S3: calculating the total weight G of the paper powder;
after multiple folds, the weight of the paper powder falling out is weighed by an electronic balance with the precision of 0.0001 g. The weighing method is divided into two methods:
the first one is: in step S1, the weight of the paper 4 is weighed as G before the paper 4 is folded1It will be understood that if the same sheet 4 is creased a plurality of times, the weight of a single sheet 4 is weighed, and if different sheets 4 are creased, the total weight of all the sheets 4 is weighed; in the step S2, the step S1 is repeated n times to weigh the sheet 4 as G2Similarly, if the same paper 4 is folded for multiple times, the weight of a single paper 4 is weighed, and if different papers 4 are folded, the total weight of all the papers 4 is weighed; in step S3, G ═ G (total weight of paper powder)1-G2). Need not collect the paper dust, need not consider whether there is the problem of omitting in the paper dust collection process, convenient operation.
The second method is as follows: s1, weighing a box, and collecting the total weight G3Cleaning the paper powder at the crease to be collectedCollecting the boxes; s3, weighing the total weight G of the collecting box containing the paper powder4The total weight of the paper powder G ═ G (G)4-G3). The paper powder is collected in the collecting box and then weighed, the collecting box occupies a small space, and the paper powder is conveniently placed on an electronic balance for weighing.
S4: degree of dusting of paper 4
Detecting the fold S at each time in the stepkAll added to give the median length of the fold
The total weight of the paper powder falling out in each detection step is G, and the powder explosion degree of the paper 4 is calculated
