METHOD FOR PRODUCING MATRIX, MATRIX AND METHOD OF PRODUCING MICROSTRUCTURE RELIEF OF LIGHT-DIFFUSING PANEL AND ITS USE

摘要

FIELD: metallurgy. ^ SUBSTANCE: method of manufacturing a matrix to produce a microstructure relief on the surface of a light-diffusing panel includes creation of a model of the surface with preset microstructure relief by applying an adhesive on a sheet of acid-resistant material, placing over it a layer of a mixture made of fractions of hard crystalline rocks, applying a metallic coating to create an electrical contact with subsequent formation of galvanic metallic sediment, which is separated from the model and the metal matrix with a preset microsructure relief is shaped. The method of producing a microstructure relief on the surface of a light-diffusing panel is characterised by the fact that the surface of the light-diffusing panel with a microstructure relief is formed by die casting and a casting mould is used to place a matrix containing on its surface a copy of the preset microstructure relief produced by the above method. ^ EFFECT: creation of a cost-effective method to produce a surface relief of the light-diffusing panel from optically transparent polymer with a size of irregularities 500-50000 nm. ^ 7 cl
