Embodiment Construction

[0024] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detail in conjunction with the preferred embodiments of the specification, but the scope of protection of the present invention is not limited to the following specific embodiments. It should be noted that, without conflict, embodiments of the present invention and features in the embodiments may be combined with each other.

[0025] Embodiments of the present invention discloses a test method for the degree of crosslinking of white adhesive film of photovoltaic modules, comprising the following steps:

[0026] S1, the balance with an accuracy of 0.1 mg weighs the weight of the screen W 1 ；

[0027] S2, the white film sample is made into small particle size particles, screened to the preset particle size, using a 0.1mg precision balance to weigh the weight of the screen after the test sample is loaded 2 ； W 2 ＝S 1 +S 2 , i.e. the weight of the...

Abstract

The invention discloses a method for testing the crosslinking degree of a white adhesive film of a photovoltaic module, and the crosslinking degree of the white adhesive film of the photovoltaic module is calculated according to the following formula: C = ((S3 + S2)-W1) / ((S1 + S2)-W1) * 100%, and C is the crosslinking degree. The result of the white adhesive film calculated by the calculation method disclosed by the invention is an accurate value instead of a reference value, the difference of crosslinking degree results of resin matrixes of different manufacturers and different batches can be effectively monitored, and the experiment time and the experiment cost are not increased on the basis of the prior art.

Description

Technical field [0001] The present invention relates to the field of photovoltaic module technology, the present invention relates to a test method for the crosslinking degree of white adhesive film of photovoltaic modules. Background [0002] Increasing the power of modules is a trend in the current photovoltaic industry, more and more module companies use high-efficiency cells, high-density packaging, white film collocation and other technologies are more and more used in module manufacturing ends, but for the white film crosslinking degree calculation method the results are only reference values, not accurate values, in order to white film can more accurately reflect the crosslinking degree of the test results, so the calculation method needs to be corrected. [0003] The existing method uses a white adhesive film composed of titanium dioxide and a resin matrix, and the crosslinking degree result calculation is mainly the result of the resin matrix in xylene, but the current ...
