As can be seen from the table, automatic tests were performed under the set conditions, and the tests were divided into 4 groups of 4 drying times such as 4, 8, 12, and 16 seconds, and each group was performed 4 times. The covering paper has residual stitches at the 4 th and 8 th seconds, and the stitches are judged to be not completely dried; and at 12 th and 16 th seconds, no residual stitches exist in the covering paper, and the stitches are judged to be completely dry. Therefore, the drying time of the stitches of the writing instrument is between 9 and 12 seconds, and additional tests are needed to obtain a more detailed drying time interval.

Compared with the national standard, the drying time range which can be actually measured by the test set is more accurate.

The test results are shown in table 4.

TABLE 4 test results of the dryness of the gel ink cartridge (8-12 seconds)

As can be seen from the table, automatic tests were performed under the set conditions, and the tests were divided into 5 groups of drying times of 8, 9, 10, 11, 12 seconds, etc., and each group was performed 4 times. Wherein, the covering paper has residual stitches at the 8 th and the 9 th seconds, and the stitches are judged to be not completely dry; at the 12 th second, no trace remained on the cover paper, and the trace was judged to be completely dried, whereas at the 10 th and 11 th seconds, different test times were observed, and the trace was sometimes dried or not dried. The writing instrument therefore has a stitch drying time of between 10 and 12 seconds.

The range of drying times actually measured in this set of experiments can be used as quantitative characterization data.

Test example five

The test sample adopts a gel ink ball-point pen refill as a test pen (the pen point is a 0.5mm pen point of a gel ink tube, and the ink is black ink of a gel quick-drying pigment). The test conditions were set as follows:

As can be seen from the table, automatic tests were performed under the set conditions, and the tests were divided into 5 groups of drying times of 2, 3, 4, 5, 6 seconds, etc., and 3 times of tests were performed for each group. Wherein, the covering paper has residual stitches at the time of 2 seconds, the stitches are integrally scratched, and the stitches are judged to be not completely dry; covering the paper stitch in the 3 rd second, wherein two results of the thread trace residue and the non-thread trace residue exist at the same time, scraping the corner of the writing paper stitch, and judging that the stitch is not completely dry; at the 4 th second, the covering paper stitch has two results of line mark residue and no line mark residue, and the writing paper stitch also has two results of corner scratch and no scratch, and the whole is judged to be two groups of undried stitches and 1 group of dried stitches; no residual stitches are left on the stitch covering paper at the 5 th and 6 th seconds, no scratch is left on the stitches of the writing paper, and the stitches are judged to be completely dry. The writing instrument therefore has a stitch drying time of between 4 and 5 seconds.

The test of the group comprehensively considers the dryness results of the stitch covering condition and the writing stitch condition, and the requirement that no residual stitches are left on the covering paper and no scratch marks are left on the writing paper is met at the same time, so that the stitch can be judged to be dry.

The test results are shown in table 6.

TABLE 6 test results of dryness (8-16 sec) of emulsified black pen core

As can be seen from the table, automatic tests were performed under the set conditions, and the tests were performed 3 times for 5 groups of drying times such as 8, 10, 12, 14, and 16 seconds. Wherein, the covering paper has residual stitches at the time of 8 seconds, the stitches are integrally scratched, and the stitches are judged to be not completely dry; covering the paper stitch in the 10 th second, wherein two results of the remaining of the line stitch and the remaining of the non-line stitch exist at the same time, scraping the corner of the writing paper stitch, and judging that the stitch is not completely dry; no residue is left in the covered paper stitches at 12 th and 14 th seconds, and two results of corner scratching and no scratching exist in the stitches, so that the two groups of stitches are judged to be not completely dry as a whole; no residual stitches are left on the stitch covering paper at the 16 th second, no scratch is left on the written stitches, and the stitches are judged to be completely dry. The writing instrument therefore has a stitch drying time of between 14 and 16 seconds.

The test of the group comprehensively considers the dryness results of the stitch covering condition and the writing stitch condition, and the requirement that no residual stitches are left on the covering paper and no scratch marks are left on the writing paper is met at the same time, so that the stitch can be judged to be dry.

It can be seen from test examples 1-6 that the writing trace drying time measuring device of the present invention can qualitatively or quantitatively measure the drying condition of writing traces of different samples under different conditions, scientifically and reasonably characterize the trace drying performance of writing tools, and provide powerful scientific and technological support for the improvement of product quality and the research and development of new products.
