Abstract
1. Способ шлифования и полирования крупногабаритных стеклозаготовок, включающий начальную, промежуточную и окончательную стадии шлифования поверхности стеклозаготовки шлифпорошком, отличающийся тем, что после каждой стадии шлифования стекло подвергают воздействию травильного раствора, содержащего смесь плавиковой кислоты, серной кислоты и воды, с последующей промывкой поверхности стекла водой, после чего поверхность стекла полируют на глубину 2-5 мкм.2. Способ по п. 1, отличающийся тем,что начальную стадию шлифования проводят шлифпорошком зернистостью 40-60 мкм на глубину 120-150 мкм, промежуточную стадию шлифования проводят шлифпорошком зернистостью 20-40 мкм на глубину 20-30 мкм, а окончательную стадию шлифования проводят шлифпорошком зернистостью 10-20 мкм на глубину 10-15 мкм.3. Способ по п. 1, отличающийся тем, что травление стеклозаготовок производят при температуре раствора 10-25°С в течение 30-60 мин поэтапно, причем продолжительность каждого этапа составляет 2-20 мин, а после каждого этапа стекло промывают теплой водой в течение 5-10 мин.1. A method of grinding and polishing large-sized glass workpieces, including the initial, intermediate and final stages of grinding the glass workpiece surface with grinding powder, characterized in that after each grinding step the glass is exposed to an etching solution containing a mixture of hydrofluoric acid, sulfuric acid and water, followed by washing the glass surface water, after which the glass surface is polished to a depth of 2-5 microns. 2. The method according to claim 1, characterized in that the initial grinding stage is carried out with grinding powder with a grain size of 40-60 μm to a depth of 120-150 μm, the intermediate grinding stage is carried out with grinding powder with a grain size of 20-40 μm to a depth of 20-30 μm, and the final grinding stage is carried out with grinding powder grain size 10-20 microns to a depth of 10-15 microns. 3. The method according to claim 1, characterized in that the glass workpieces are etched at a solution temperature of 10-25 ° C for 30-60 minutes in stages, the duration of each step being 2-20 minutes, and after each step the glass is washed with warm water for 5 -10 min.
