The application discloses a method for improving the width of a polarized film, which comprises the following steps: after the production raw material PVA element of the polarized film is washed, the PVA element is pre-dried and shaped, and then is sent into an oven for drying; the pre-drying and shaping is performed by using two corresponding hot air pipes, the two hot air pipes are located on the upper surface and the lower surface of the PVA element respectively, the hot air pipes are not in contact with the PVA element, and the two hot air pipes respectively blow out hot air streams with a temperature of 80 DEG C to 120 DEG C towards the upper surface and the lower surface of the PVA element; the method overcomes the defects of the prior art, the width shrinkage rate of the PVA element before and after drying is less than 10%, and the polarization degree and the transmittance of the PVA element are ensured.

The utility model discloses a rock wool board connecting structure which comprises two sets of connecting pieces arranged side by side, the two sets of connecting pieces are connected through a telescopic connecting unit, first through holes are formed in the two ends of an upper pressing plate, second through holes corresponding to the first through holes are formed in the two ends of a lower pressing plate, a first pipe column is fixedly connected to the bottom side of the upper pressing plate, and a second pipe column is fixedly connected to the bottom side of the lower pressing plate. A second tubular column is arranged on the upper side of the lower pressing plate, a sliding hole in sliding fit with the second tubular column is formed in the lower end of the first tubular column, the inner diameter of the first through hole is equal to that of the second through hole, the inner diameter of the first tubular column is equal to that of the second tubular column, and the upper pressing plate and the lower pressing plate are connected through a bolt penetrating through the first through hole and the second through hole. According to the rock wool board connecting structure, two rock wool boards can be stably connected through a plurality of rock wool board connecting structures, the mounting position can be finely adjusted according to the preset hole distance in the rock wool boards, the universality of the rock wool board connecting structure is improved, and meanwhile, a butt joint mode is adopted for connection, so that compared with an existing insertion type connecting mode, the needed assembling space is smaller.
