Test method.
Background technology
In solar double-glass assemblies, the mobility of encapsulating material is to evaluate an important parameter of glued membrane characteristic, mobility it is big
It is small to directly influence during component lamination that component residual silkgum content, component thickness after bubble discharge, lamination, cell piece is hidden splits, mesh
The method of preceding evaluation glued membrane mobility has following two：
(1) glued membrane is extrudability：Under certain pressure, melting glued membrane is by determining the extrusion length in hole；This method sample preparation is simple, can
Mobility quantizating index is obtained, but differs larger with the true laminating technology of component, referential is relatively low.
(2) lamination widgets are made：Different glued membrane widgets laminations are made, excessive glue effect after observation lamination judges glued membrane
Mobility；This method is close to the true laminating technology of component, but sample preparation is cumbersome and artificial observation excessive glue result is inaccurate, neither one
The judge index of quantization.
Invention content
The technical problem to be solved in the present invention is to provide a kind of sample preparation samplings close to true lamination process, and sample preparation is simple, surveys
Test result quantizes, accuracy high photovoltaic module encapsulating material fluidity testing method.
In order to solve the above-mentioned technical problem, photovoltaic module of the invention encapsulating material fluidity testing method, including with
Lower step：
A, prepare two pieces of glass samples, in addition, cutting two pieces of high temperature cloths；
B, double-deck film sample A, B, C, D of different type encapsulating material are made；
C, glass sample, high temperature cloth, film sample are stacked into alignment successively from outside to inside, gives A, B, C, D tetra- double respectively
Layer film sample marks to form laminate；
D, the laminate of step C is laminated, the double-deck film sample is taken out after lamination and measures tetra- samples of A, B, C, D respectively
Diameter after product lamination and record.
The area ratio of the area of sample and the preceding sample of lamination indicates after the size lamination of glued membrane mobility
kABCD：After different film samples are laminated and lamination front product ratio
dABCD：Diameter/mm after different film sample laminations.
