Method for producing structural polycarbonate sheet Russian patent published in 2023 - IPC A01G9/22 E04C2/54 

FIELD: agriculture.

SUBSTANCE: dosing of the initial raw materials containing granular polycarbonate, feeding them to the extruder, where they are melted and formed with the help of the extruder forming head of the sheet structure, after the forming head the melt is fed to the calibrator plates, the formed sheet is moved between them using pulling devices installed after calibrator, before feeding to the extruder, granules of polycarbonate are added to the granular polycarbonate and mixed with it, in the polymer matrix of which particles of a light-scattering optical component are embedded, providing diffuse transmission or diffuse reflection of the incident light flux, regardless of its direction to change the angles of transmission and reflection of light rays, in the ratio wt.%: polycarbonate granules with a light-scattering optical component - 0.01-40; granular polycarbonate - the rest is up to 100 wt.% of the mixture.

EFFECT: ensuring the creation of stimulating photosynthesis diffuse shadowless natural lighting when using a sheet of cellular polycarbonate made from a composite mixture as a covering material for greenhouses, greenhouses, winter gardens.
