Detailed description of the invention
In Fig. 1, airplane skin 1 has adhered layer 2, adhered layer 2 has heater mat 3, heater mat 3 has adhered layer 2, adhered layer 2 has film 4.---heater mat---adhered layer---film, can multilayer repeatedly as required for adhered layer.In practical application, adhered layer 2 can be independent one deck, also can be the adhesive-layer (be commonly called as " gum) that film 4 inherently adheres to; Also can be mixed with conductive material in adhered layer 2, namely heater mat 3 and adhered layer 2-in-1 two be one.
In Fig. 2, whole film is spliced by polylith film piecemeal 6, every block film piecemeal 6 and adjacent between form piecemeal splicing line 5.
In Fig. 3, bulk film, it has cut-off rule 7 be divided into film piecemeal 6; Cut-off rule 7 can be the line as the sawtooth hole composition on stamp, also can be the line of cut do not cut, certainly may also be by any way be conducive to reduce the disposal that bulk strength and being conducive to tears from cut-off rule.
In Fig. 4, fervent secant 8 is made up of heating wire, and fervent secant 8 layout setting will coincide with piecemeal splicing line 5 or cut-off rule 7, and fervent secant is electrically connected with heating power supply 9 by wire 10.
Embodiment 1
On airplane skin 1 surface, to be spliced bulk and even whole film 4 with polylith film piecemeal 6, every block film piecemeal 6 is independent, forms piecemeal splicing line 5 between adjacent, in piecemeal splicing line 5 corresponding position, be distributed with the fervent secant 8 of resistor wire composition, between film 4 and airplane skin 1, and between film 4 and film 4, there is heater mat 3, after airplane skin 1 freezes, connect heater mat 3 heating power supply 9, and connect the fervent secant 8 be made up of resistor wire, like this, ice sheet 11 melts from piecemeal splicing line 5 or cut-off rule 7 place by fervent secant 8, ice sheet 11 is made to form the thawing line matched with the piecemeal splicing line 5 of film piecemeal 6, namely ice sheet is cut into the sheet ice sheet of fritter one fritter by fervent secant 8, at this moment, owing to connecting the heating power supply 9 of heater mat 3, thus adhered layer 2 also heats by heater mat 3, after adhered layer 2 is heated, viscosity declines, thus ice sheet 11 is peeled off down by one piece of block, serve deicing effect, heater mat 3 is Electric radiant Heating Film preferably.
Embodiment 2
Embodiment 2 is roughly the same with embodiment 1, difference be embodiment 2 be the bulk film having cut-off rule 7, after airplane skin 1 freezes, connect heating power supply 9 and fervent secant 8 power supply of heater mat 3, film 4 is torn from cut-off rule 7 and peels off, and is also torn from cut-off rule 7 peels off with one piece of ice cube layer 11.
Described film 4 is the film of any Pasting.Cut-off rule 7 is physical segmentation or chemical method segmentation.
Embodiment 3
In Fig. 5,5. piecemeal splicing line, 6. film piecemeal, 12. folded projections.Folded projections 12 is exactly by edge fold in the edge of film piecemeal 6, form the folded projections 12 with film piecemeal 6 plane certain angle, after the effect of this folded projections 12 is film piecemeal 6 freezes, by the ice sheet that comes off film piecemeal 6 can be torn from splicing line 5 by the tightly coated folded projections 12 of ice sheet 11 and drop.
Embodiment 4
In Fig. 6,5. piecemeal splicing line, 6. film piecemeal, 13. additional projection.Additional projection 13 is exactly the edge's additional projection thing at film piecemeal 6, form additional projection 13, after the effect of this additional projection 13 is film piecemeal 6 freezes, by the ice sheet that comes off film piecemeal 6 can be torn from splicing line 5 by the tightly coated additional projection 13 of ice sheet 11 and drop.This additional projection 13 can be original setting on film piecemeal 6, also can add up by suppressing or pasting.
Described adhered layer (2) is heat-foamable material, refers in viscose glue and is added with the material that heat produces bubble.When heater mat 3 heats, in viscose glue, produce bubble, film 4 is heaved, reduces its adhesion firmness, be convenient to it and carry ice sheet 11 and together peel off.
Described film 4 is heat deformable material, refers to that film 4 can adopt heat-shrinkage material, thermal expansion material and other heat deformable material.When heater mat 3 heats, the film 4 be made up of heat deformable material on it or contraction, or expand, or do other distortion, be convenient to its ice sheet 11 carried on it and come off.
Described film 4 is heat softener material, and referring to that film 4 adopts after heated can deliquescing, the material that even can liquefy or vaporize, and is also that just ice sheet 11 is thereon peeled off.Described film (4) comprises paper, plastics, textile cloth, nonwoven cloth, silk screen, all planar solid things of filter screen, also comprises that can brush and be sprayed on solid can the liquid coating of film former, and this liquid coating is wanted to solidify.Actual to use, can by film coating and adhered layer and the two-in-one or three-in-one application of heater mat.Such as, can add conductive material in adhered layer, form thin film layer, be also film coating, adhered layer and heater mat three laminated.
