Diffusion membrane, method for producing the same, and use thereof

ActiveCN115542441BImprove transmittanceimprove clarityDiffusing elementsPhysical chemistryOptical transmittance
This application relates to the field of optical thin film technology, and more particularly to a diffusion film, its preparation method, and its application. A diffusion film is provided, comprising a substrate and a diffusion film disposed on any surface of the substrate. The diffusion film is prepared from components with the following mass percentages: 0.5%–10% diffusion particles and 90–99.5% solvent. The resulting diffusion film exhibits high haze, high clarity, and high light transmittance. The provided formula is simple, reduces the use of other components, is low in cost, facilitates the dispersion of diffusion particles, achieves ideal light diffusion effects, and is suitable for widespread use.

Wind-resistant linkage photovoltaic support

ActiveCN224289698UDoes not increase thicknessLittle change in wind areaPhotovoltaic supportsPhotovoltaic energy generationSupporting systemClassical mechanics
The utility model discloses a wind-resistant linkage photovoltaic support, which relates to the field of photovoltaic supports and comprises a photovoltaic panel, a longitudinal beam, a cross beam and a wind-resistant linkage mechanism. And the wind-resistant linkage mechanism comprises a supporting arm, a nut seat, a screw rod, a motor and a second bearing seat. Wherein the supporting arm movably penetrates through the longitudinal beam, the upper end of the supporting arm is rotatably connected with an outer frame of the photovoltaic panel, the lower end of the supporting arm is rotatably connected with the nut seat, meanwhile, the screw matched with the nut seat is rotatably and fixedly arranged on the lower end face of the longitudinal beam, the nut seat slides along the longitudinal beam through rotation of the screw, and then the supporting arm drives the photovoltaic panel to turn over. And the photovoltaic panel can be folded and clung to the longitudinal beam in a strong wind day, so that windward stress on the upper and lower end surfaces of the photovoltaic panel is avoided, and the wind resistance is improved. Moreover, the supporting arms penetrate through the longitudinal beams, and the screw rods and the nut seats are assembled on the lower end surfaces of the longitudinal beams and are positioned between the cross beams and the longitudinal beams, so that the thickness of the whole photovoltaic bracket is not increased.
