when the film is pasted, the lower protective layer is removed, and the film body is placed on the clean surface of the screen; the fingers touch the peripheral side edges of the film body to enable the film body to face the mobile phone screen; after the lower protective layer is taken down, the film body is opposite to the surface of the screen, the bead protrusions are adjusted, so that a structure similar to a frosted surface is formed on the surface of the film body, at the moment, the contact area between the film body and the screen is greatly reduced, the electrostatic attraction force between the film body and the screen is small, the film body can be easily moved, and two-dimensional and staggered air channels are formed between the screen and the laminating layer due to the fact that the bead protrusions are adjusted and supported between the screen and the laminating layer; after the position of the membrane body is adjusted to be standard, the upper protective layer is pressed downwards, so that the adjusting microbeads are tightly attached to the screen; slowly taking down the upper protective layer, and pressing the film body to the screen; at the moment, the binding layer is directly contacted with the screen and is tightly absorbed under the action of electrostatic adsorption force; in the laminating process, air bubbles between the film body and the screen are discharged through the air channel, so that the generation of the air bubbles is effectively prevented; along with pressing of finger, the laminating layer of matter soft adsorbs gradually on the screen, adjusts microballon protrusion in laminating layer this moment to form dull polish surface, effectively prevent the adhesion of fingerprint, oil stain, guarantee bright and clean, the same direction as smooth of screen.

The mobile phone film has the advantages that the attachment layer is soft in texture, even if fine dust appears on the screen, the attachment layer can wrap the screen and weaken the existence sense of the screen, so that when the mobile phone film is used, the dust can be weakened and hidden, the smoothness and smoothness of the screen are guaranteed, bubbles are effectively prevented from being generated, the hand feeling can be improved, the attachment is convenient, the success rate of the attachment is effectively improved, the smoothness and the attractiveness of the screen are greatly improved, and the pushing value is high.

Preferably, the membrane body comprises two closely attached attaching layers, and the adjusting beads are arranged between the two attaching layers; during production and processing, the adjusting microbeads are uniformly sputtered on the lower binding layer, and then the upper binding layer is subjected to hot melting binding; the structure can greatly simplify the production flow, simultaneously ensure that the adjusting micro-beads are in the interior of the attaching layer, and can not cause the exposing or falling of the adjusting micro-beads due to the deficiency of the production precision, thereby effectively improving the quality of the membrane body.

Preferably, the thermal expansion bumps are arranged on the surface of the upper protective layer opposite to the film body at equal intervals, and after the film body is attached, the thermal expansion bumps are expanded by heating the upper protective layer, so that the attachment layer is pressed to the screen, thereby promoting the firm adsorption of the film body.

Preferably, , the thermal expansion bumps are adhered to the upper protective layer in sheet form at low temperature and bulge to form a hemisphere at high temperature, which facilitates the adjustment of the film body and the fixation and adsorption of the film body.

, preferably, the thermal expansion material is sprayed uniformly onto surface of the upper protective layer to form an atomized surface, after the atomized liquid drops solidify, the other surface of the upper protective layer is heated, and the atomized surface is pressed by a pressing plate coated with an anti-sticking agent, and the atomized liquid drops gradually soften with the temperature rise and are pressed by the pressing plate to form a flat sheet to be attached to the upper protective layer.

Preferably, an adjusting edge strip is further arranged on the upper protection layer; so as to facilitate the convenient movement and adjustment of the membrane body for users.

Preferably, the upper protective layer is made of a good heat conduction material, such as an iron sheet and an aluminum sheet.
