3. The scheme retains samples, and the samples can be collected and processed uniformly or displayed to a reviewing institution or a client.

4. The box cover is movable, can be taken down for sampling, and is flexible and convenient.

Drawings

FIG. 1 is a schematic structural view of a surface dry sampling plate provided by the present invention;

in the figure, 1-foam board, 2-box cover and 3-wood board.

Detailed Description

The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiment of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a monitoring method for the surface drying time of a pouring sealant of an MWT component, which is characterized in that the pouring sealant is sampled at regular time, and samples taken at different time points are placed in a surface drying sampling plate for comparison;

Further, six samples are sampled within one shift, and the pouring sealant is sampled once every 2 hours; the next day the sample was removed from the box lid 2 and placed in the box.

The utility model also provides a surface drying sampling plate, which comprises foam, a wood plate 3 and a conductive adhesive box cover 2, wherein the wood plate 3 is arranged at the bottom and plays a role of supporting the bottom; the foam plate 1 is arranged in the middle and plays a role in fixing; a plurality of holes are formed in the foam plate 1 and used for containing glue, and the conductive adhesive box cover 2 is arranged in the holes.

The foam board 1 is provided with 12 round holes with the same size as the box cover 2, and then the round holes are fixed on the wood board 3 by AB glue, and the box cover 2 is fixed by the elasticity of foam.

Furthermore, the wood board 3 is used for supporting the bottom to prevent the box cover 2 containing the glue from falling off, and the box cover 2 can be taken down to facilitate sampling.

As shown in figure 1, when in use, the box cover 2 is sequentially taken down from the foam, the box cover 2 is held by hand until the rubber tube is sampled down, and then the rubber tube is put back to the hole position on the foam to be fixed. Sampling every two hours, recording the surface drying time, and pressing the previous sample to know the current curing condition of the components entering the curing room before two hours. Six samples were taken for one shift and pooled the next day.

The sampling times are theoretically as large as possible, and cannot be as small as possible, and six times of sampling in 12 hours is suitable. The six samples can be regarded as the instantaneous state of the whole curing process at the 6 time points, and the observation of the samples can approximately deduce the curing condition of the components entering the curing room at different times.
