the concave depth of the grid exhaust groove is not more than 20% of the thickness of the release film, so that the overall stability of the release film is ensured;
the concave depth of the grid exhaust groove is not more than 15% of the thickness of the glue layer of the glue body, so that the overall viscosity of the glue body is ensured;
the grid exhaust grooves comprise warp grooves and weft grooves, and the warp grooves and the weft grooves are spliced and combined with each other to form all grid exhaust grooves with the same size;
the widths of the warp slots and the weft slots are the same and are both 0.05 mm-0.1 mm, so that the stable and reliable air exhaust is ensured;
the bottom of the radial groove and the bottom of the weft groove are all semicircular surfaces, so that excessive force cannot be generated when gas circulates, and the grid exhaust groove is stable and reliable in exhaust.
After the adhesive tape is adopted, the grid exhaust grooves are arranged in the adhesive area between the adhesive body and the release film, the grid exhaust grooves are positioned in the thickness direction and extend to the whole adhesive area, the thickness of the grid exhaust grooves is not more than the adhesive layer thickness of the adhesive body or the thickness of the release film, and redundant gas is exhausted along the grid exhaust grooves after the adhesive body is flatly pasted, so that the surface of the adhesive body after being flatly pasted is flat, and the subsequent stable and reliable use of a product is ensured.

Detailed Description
A colloid flat pasting process, which is shown in figures 1-3: set up net air discharge duct 30 in the adhesive surface region that forms between glue film 11 of colloid 10 and from type membrane 20, net air discharge duct 30 is located the thickness direction, extends to whole adhesion region, and the thickness of net air discharge duct 30 is not more than glue film 11 thickness of colloid 10 or from the thickness of type membrane 20.
After the colloid 10 and the release film 20 are flatly pressed, the whole composite structure is kept stand for 18-24 hours, so that redundant air is discharged out of the grid exhaust groove 30, and the colloid 10 and the release film 20 are flatly and reliably pasted.
In the first embodiment, a release film 20 with grid air discharge grooves 30 is covered on the adhesive surface of a colloid 10; the ratio of the total area of the grid exhaust grooves 30 to the total area of the adhering surface area is 0.5-1.5%, and the integral flatness after adhering is ensured; the concave depth of the grid vent groove is not more than 20% of the thickness of the release film, and the integral stability of the release film is ensured.
In the second embodiment, the grid air vent groove 30 is formed on the adhesive surface of the colloid 10, so that the inner surface of the release film 20 is flatly attached to the whole outer plane area of the grid air vent groove 30. The ratio of the total area of the grid exhaust grooves 30 to the total area of the adhering surface area is 0.5-1.5%, and the integral flatness after adhering is ensured;
the concave depth of the grid exhaust grooves 30 is not more than 15% of the thickness of the glue layer 11 of the glue body 10, and the overall viscosity of the glue body 10 is ensured.
In the first and second embodiments, the grid exhaust grooves 30 include the warp grooves 31 and the weft grooves 32, and the warp grooves 31 and the weft grooves 32 are spliced and combined with each other to form all grid exhaust grooves 30 with the same grid size;
