Изобретение относитс к области ироизводства зеркал на стекл нной основе.This invention relates to the manufacture of glass-based mirrors.
Известен сиособ сн ти зеркального алюминиевого сло путем обработки в гор чем растворе концентрированных щелочей в течение 20-30 м«н.A known method for removing a mirror aluminum layer is by treating in a hot solution concentrated alkali for 20-30 m.
Цель изобретени - ускорение процесса, исключение токсичности пронзводства.The purpose of the invention is to accelerate the process, eliminating the toxicity of the production.
Цель достигаетс тем, что обработку осуществл ют 1--5%-иым раствором нейтральной соли металла с 6o;iee электроноложительным иотеициалом, чем у А1, HaHpiiMep FeCla, при комнатной темиературе в течение 1-2 мгга.The goal is achieved in that the treatment is carried out with a 1--5% solution of a neutral metal salt with 6 °; i.e., an electron-positive and theo-etical than A1, HaHpiiMep FeCla, at room temperature for 1-2 mgg.
Снособ осуществл етс следующим образом. Сначала с зеркала снимают бнту.мный слой уайтсниртом и лаковый слой - бутилацетатом. Зеркало с обнаженным алюминиевым слоем иогружают в ваниу, нанолнениую нойтральиым раствором FeCls концентрации 1%. Удаленне алюмин евого зеркального иокрыти производ т ири комиатиой темиературе в течение 1-2 мин, а затем очщцениое стекло иромывают проточной водой.The method is carried out as follows. First, remove the airfoil from the mirror. White layer and lacquer layer - butylacetate. The mirror with the exposed aluminum layer is immersed in vanilla applied by a neutral solution FeCls with a concentration of 1%. Remotely, the aluminum mirror and cover is made with a terature for 1-2 minutes, and then the glass is washed with running water.
Предмет изобретени Subject invention
Способ удалени алюминиевого зеркального покрыти со стекла иутел обработки раствором , отличающийс тем, что, с целью ускоренн нроцесса, исключени токсичности ироизводства, обработку осуихествл ют 1 - 5%-ным раствором нейтральной соли металла с более электроположительным потенциалом, чем у А1, например FeCU, при комиатиой темиературе в течение 1---2 ми).The method of removing the aluminum mirror coating from the glass and the treatment solution, characterized in that, in order to accelerate the process, eliminate the toxicity of production, the processing is 1-5% solution of a neutral metal salt with a more electropositive potential than that of A1, for example FeCU, with commatized temeture for 1 --- 2 mi.
