Description
не наблюдаетс вьаделени непри тного запаха).there is no objectionable smell).
Способ применени . Готов т раствор 50 г (4 столовые ложки) средства на 1 л воды, заполн ют им посуду на 3/4 объема и кип т т 30 мин. При большом слое накипи раствор оставл ют до охлаждени , после чего посуду промывают водой. При неполном удалении накипи обработку повтор ют.Method of application. Prepare a solution of 50 g (4 tablespoons) of product per 1 liter of water, fill the dishes with 3/4 volume and boil for 30 minutes. With a large layer of scale, the solution is left to cool, after which the dishes are washed with water. In case of incomplete descaling, the treatment is repeated.
Несколько составов предлагаемой композицииSeveral formulations of the proposed composition
Из перечисленных компонентов был составлен р д композиций и определены эффективность удалени накипи и рн рабочего раствора, обеспечивающего сохранность эмали.A number of compositions were compiled from the listed components and the effectiveness of the removal of scale and the pH of the working solution, ensuring the safety of enamel, were determined.
Оценку эффективности удалени накипи и повреждаемости эмалированной поверхности проводили по известным методам. Результаты приведены в табл. 1 и 2.Evaluation of the effectiveness of descaling and damage to the enamelled surface was carried out by known methods. The results are shown in Table. 1 and 2.
