Abstract
The utility model provides a PVB (polyvinylbutyral) film creep deformation test device comprising two pieces of test glass, a laminating machine which is used for laminating the test glass and a to-be-tested PVB film into a test sample after the test glass is overlapped with the to-be-tested PVB film, and an aging oven for accommodating the test sample, wherein a test board is arranged in the aging oven at a certain test angle and is used for fixing the test sample.
Description
Technical field
The utility model relates to PVB film creep technical field of measurement and test, relates in particular to a kind of PVB film creep proving installation.
Background technology
Polyvinyl butyral (PVB) glued membrane with its excellent shock resistance, transparency, with glassy bond and elasticity etc., be all the preferred material of building and automobile industry laminated glass all the time.Along with the fast development in BIPV market, PVB glued membrane is more and more applied to photovoltaic encapsulation material market.But, because PVB is thermoplastic macromolecule material, in lamination process, there is not cross-linking reaction, when being subject to stress, middle PVB film will occur relatively to flow, i.e. so-called creep.Creep be solid material in the situation that being subject to stress, strain increases and produces the situation of non-recoverable deformation along with time lengthening.Therefore, photovoltaic module, in long-term use procedure, just probably produces relative displacement between levels glass, causes that it exists cell piece hiddenly to split, solder joint is thrown off, the loosening equivalent risk of terminal box.Particularly, when the setting angle of photovoltaic module is larger, these risks will be aggravated, and even produce potential safety hazard.
Therefore, be necessary to provide a kind of PVB film creep proving installation to address the above problem.
Utility model content
The purpose of this utility model is to provide a kind of film of PVB simply and easily creep proving installation.
For realizing above-mentioned utility model object, the utility model provides a kind of PVB film creep proving installation, it comprises two built-in testing glass, in order to by the ageing oven that is laminated into the laminating machine of test sample and accommodates test sample after tested glass and PVB film to be measured overlap joint, in described ageing oven, be provided with certain test angle setting and in order to the test board of fixing test sample.
As further improvement of the utility model, two described tested glass sizes are identical, and the length of tested glass is that 100mm to 200mm, width are 10mm to 40mm described in every a slice.
As further improvement of the utility model, two described tested glass lap of splice when test is 40mm to 100mm.
As further improvement of the utility model, described proving installation also comprises the counterweight that is fixed to tested glass lower end, and the quality of described counterweight is no more than 200g.
As further improvement of the utility model, described test angle is 0 ° to 90 °.
The beneficial effects of the utility model are: the utility model PVB film proving installation form simple, cost is low and easy to operate, can meet production and the testing of equipment condition of various photovoltaic modulies, easily apply.
Accompanying drawing explanation
Fig. 1 is the front view of the test sample that forms after two built-in testing glass and PVB film lamination to be measured in the utility model PVB film creep proving installation.
Fig. 2 is the side view of test sample in Fig. 1;
Fig. 3 is part schematic diagram when test sample in Fig. 1 is positioned in an ageing oven, and demonstration test sample is placed with a test angle, and below is fixed with a counterweight.
Specific embodiment
Below with reference to embodiment shown in the drawings, the utility model is described in detail.But these embodiment do not limit the utility model, structure or the conversion in function that those of ordinary skill in the art makes according to these embodiment are all included in protection domain of the present utility model.
Please refer to Fig. 1 to a preferred embodiment that Figure 3 shows that the utility model PVB film creep proving installation.Described PVB film creep proving installation comprises two built-in testing glass 1, after tested glass 1 and PVB film 8 to be measured are overlapped, is laminated into the laminating machine (not shown) of test sample 100 and the ageing oven 2 of accommodating test sample 100.
Two described tested glass 1 sizes are identical, and described in every a slice, the length of tested glass 1 is that 100mm to 200mm, width are 10mm to 40mm.Two described tested glass 1 lap of splice when test is 40mm to 100mm.
In described ageing oven 2, be provided with certain test angle A and arrange and in order to the test board 21 of fixing test sample 100.Described test angle A is set to 0 ° to 90 ° according to testing requirement.
In addition, described proving installation also comprises the counterweight 3 that is fixed to tested glass 1 lower end in test sample 100, and the quality of described counterweight 3 is no more than 200g, and it is mainly determined according to PVB film to be measured the actual conditions that are used.
The utility model PVB film creep proving installation in use, first, tested glass 1 and PVB film 8 to be measured are stacked together according to the order of tested glass 1, PVB film 8 to be measured, PVB film 8 to be measured, tested glass 1, make overlap joint sample, the lap of splice is 40mm to 100mm; Secondly overlap joint sample is adopted to laminating machine laminating moulding according to the state of arts of PVB film 8 user demands to be measured, for example adopt laminating machine one-shot forming, or described proving installation also includes autoclave according to demand, described test sample 100, for adopting laminating machine and autoclave post forming, is finally made test sample 100 as depicted in figs. 1 and 2; Again, in tested glass 1 lower end that is positioned at downside, fix according to demand a counterweight 3, make the stressed 0.01g/mm of being of unit overlap joint area of test sample 100 overlapping parts
2to 0.2 g/mm
2; Then test sample 100 and counterweight 3 are fixed on the test board 21 of ageing oven 2.Finally, this ageing oven 2 is set to aging condition according to demand, as various environmental baselines and times such as baking, damp and hot, ultraviolet irradiations.After finishing, digestion time can calculate the number percent of creep ，Ji test sample lap-joint slippage.
As known from the above, that the utility model PVB film proving installation forms is simple, cost is low and easy to operate, can meet production and the testing of equipment condition of various photovoltaic modulies, easily applies.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present utility model; they are not in order to limit protection domain of the present utility model, all disengaging within equivalent embodiment that the utility model skill spirit does or change all should be included in protection domain of the present utility model.
