Embodiment
See also Fig. 2 A and Fig. 2 B, Fig. 2 A is depicted as the synoptic diagram of first embodiment when attaching adhesive tape on the release layer of polaroid of the present invention, and Fig. 2 B is depicted as among Fig. 2 A polaroid along the diagrammatic cross-section of BB ' direction.The invention provides a kind of bubble removal method, bubble 3 is present between primary diaphragm 1 and the secondary diaphragm 2, and primary diaphragm 1 is oppositely arranged with secondary diaphragm 2.In the present embodiment, secondary diaphragm 2 for example is a polaroid, and corresponding primary diaphragm 1 for example is the release layer of polaroid 2, that is the polaroid shown in Figure 1A and Figure 1B.See also Fig. 3, Figure 3 shows that the process flow diagram according to bubble removal method of the present invention, among the present invention, the removal method of the bubble that polaroid 2 and its release layer are 1 may further comprise the steps:
Step S1: adhesive tape 4 is provided, and adhesive tape 4 at least one mask toughness for example are adhesive tape, but not as limit;
Step S2: attach adhesive tape 4 in the surface of primary diaphragm or release layer 1, and adhesive tape 4 extends to the edge 11 of primary diaphragm 1 and covers bubble 3 fully from bubble 3 places.Wherein, adhesive tape 4 comprises that edge 11, the second ends 41 that first end 42 and second end, 41, the first ends 42 are positioned at primary diaphragm 1 are positioned at bubble 3 places.And when adhesive tape 4 conformed to primary diaphragm 1 surface, second end 41 of adhesive tape 4 covered bubble 3 fully.And in the present embodiment, when adhesive tape 4 conformed to primary diaphragm 1 surface, first end 42 of adhesive tape 4 flushed with the edge 11 of primary diaphragm 1.
Step S3: 3 places tear off adhesive tape 4 from bubble, make bubble 3 moving with adhesive tape 4.Because in the process that tears off adhesive tape 4, miniature deformation can upwards take place in the primary diaphragm or the release layer 1 that are pasted with the zone of adhesive tape, even there are a lot of minute bubbles between primary diaphragm 1 and the secondary diaphragm, can make so originally to be dispersed in this regional bubble when primary diaphragm 1 deformation, flocking together along the space forms than air pocket;
Step S4: adhesive tape 4 is torn off edge 11 to primary diaphragm 1, and bubble 3 also can move to the edge 11 of primary diaphragm 1 along with the motion of adhesive tape 4; And
