Abstract
Řešení se týká výroby zrcadel, a to složeni směsi pro úpravu povrchu skla před napařovánim hliníku ve vakuu. Cílem je zvýšení čistoty skla a zjednodušení ruční práce. Cíle se dosahuje pomocí směsi sestávající ze 4 až 6 % hmot. oxidu zirkoničitého, 0,007 až 0,11 % hmot. koncentrované kyseliny sírové, přičemž zbytek je voda.The solution concerns the production of mirrors, namely the composition of a mixture for treating the surface of glass before vacuum evaporation of aluminum. The goal is to increase the purity of the glass and simplify manual work. The goal is achieved by using a mixture consisting of 4 to 6% by weight of zirconium dioxide, 0.007 to 0.11% by weight of concentrated sulfuric acid, with the remainder being water.
