The sample uses an emulsified ballpoint refill as a test pen (the tip is an emulsified bullet tip with a 0.7mm tip, and the ink is a black emulsified ink). The test conditions are set as:

Writing angle: 70°

Writing paper, covering paper: writing paper with a quantitative specification of 80g/m2 in accordance with GB/T12654-2008

Load weight specification: 500g special weight, bottom diameter 50mm;

Writing load: 60g

Measurement mode: automatic measurement

Stitch pattern: zigzag pattern

Photo mode: Overlay stitches + writing stitches

Paper speed: 75mm/s

Weight control mode: automatic placement (wait for 8 seconds/10 seconds/12 seconds/14 seconds/16 seconds to place, cover for 60 seconds to lift)

Paper drag: 1cm

The test results are shown in Table 6.

Table 6. Test results of emulsified black refill dryness (8-16 seconds)

It can be seen from the table that under the set conditions, the automatic test is adopted, and it is divided into 5 groups with drying time of 8, 10, 12, 14, 16 seconds, etc., and each group is tested for 3 times. Among them, at the 8th second, the covering paper has residual stitches, and the stitches are scratched as a whole, and it is determined that the stitches are not completely dry; at the 10th second, the covering paper stitches have both residual stitches and no traces. If the corners of the traces are scratched, it is judged that the stitches are not completely dry; at the 12th and 14th seconds, the cover paper has no stitches, and the stitches also have two results: corner scratches and no scratches, and the overall judgment is that the two groups are not completely dry; At the 16th second, the stitches covered the paper with no residual stitches and no scratches on the writing stitches, and it was determined that the stitches were completely dry. The stitch drying time for this writing instrument is therefore between 14-16 seconds.

This group of tests comprehensively considers the stitch coverage and the dryness results of the writing stitch. It is necessary to satisfy both that there is no residual stitch on the covering paper and no scratches on the writing paper before the stitch can be determined to be dry.

It can be seen from Test Examples 1-6 that with the aid of the writing stitch drying time measuring device of the present invention, the drying conditions of the writing stitches of different samples can be qualitatively or quantitatively measured under different conditions, and the drying conditions of the writing instruments can be scientifically and reasonably characterized. The drying performance of the stitches provides a strong scientific and technological support for the improvement of product quality and the research and development of new products.
