and 2, peeling and separating the two water-blocking films to enable POE to be attached to the two water-blocking films 102.
This embodiment cooperates through POE film and water-blocking film, the POE film that thickness is halved has been obtained, the POE film overflows to glue in having solved the encapsulation process, thickness is too thick, the outward appearance is bad, the bubble scheduling problem, it is specific, lay single-layer POE film in the middle of two-layer water-blocking film at first, and the heating makes the POE film be in the state of melting, then peel off the separation with two-layer water-blocking film, make POE adhere to on two-layer water-blocking film, because two water-blocking film adhesion force are the same, can make the POE homodisperse that melts to two water-blocking films, it only has the new POE film half of former PO.
Preferably, the single-layer POE film is laid between the two water-blocking films, and heated to be in a molten state 101, specifically:
step 1, laying a single-layer POE film between two water-blocking films to obtain a composite film layer;
and 2, heating the composite film layer for 5min at the temperature of 140 ℃, taking out, and keeping the temperature of the composite film layer unchanged.
Preferably, the two water-blocking films are peeled off and separated, so that POE is attached to the two water-blocking films 102, specifically: and (4) peeling and separating the two layers of water-blocking films through a roller device, and uniformly dispersing the molten POE film to the two water-blocking films to obtain the POE film with the thickness reduced by half. In order to facilitate the separation of the high-temperature bonded film, a surplus length can be reserved on the composite film layer as a stress position.
This preferred embodiment make full use of the hot melt characteristic of thermoplastic type POE film and the adhesive force between POE itself and the water blocking film, will purchase the thinnest POE film and become thinner. The advantage lies in can practice thrift the material and can avoid overflowing glue, thickness excessively thick, the outward appearance is bad, the bubble scheduling problem that causes owing to using too thick POE film, provides the material condition for using some experiments that need thinner POE film to because thinner POE price is higher, change the effective reduce cost of design scheme. And the treated water-blocking film and the POE are compounded, so that the laying and packaging process is more convenient and faster in the subsequent packaging process of the assembly.
Preferably, the heating mode is heating by using a laminator, and the laminator can adjust the heating time according to the heating temperature.
