Description

Изобретение касается составов шихты для получения минерального пигмента, который может быть использован для окрашивания стекла, эмали, глазури, цемента.The invention relates to compositions of the mixture to obtain a mineral pigment, which can be used for coloring glass, enamel, glaze, cement.

Известны разнообразные пигменты для окрашивания цемента, в том числе и пигменты, включающие окись хрома [1].A variety of pigments are known for coloring cement, including pigments including chromium oxide [1].

Известен пигмент коричневый, содержащий, мас.%: окись хрома 35-40; окись цинка 30-35; красный шлам 25-30 [2]. Температура обжига такого пигмента высока и составляет 1100-1120°С.Known brown pigment containing, wt.%: Chromium oxide 35-40; zinc oxide 30-35; red mud 25-30 [2]. The firing temperature of such a pigment is high and is 1100-1120 ° C.

Задача изобретения состоит в снижении температуры обжига.The objective of the invention is to reduce the firing temperature.

Задача решается тем, что в состав шихты для получения пигмента, содержащей окись хрома, окись цинка, красный шлам, дополнительно вводят доломит, при следующем соотношении компонентов, мас.%: окись хрома 20-30; окись цинка 5-10; красный шлам 25-35; доломит 35-40.The problem is solved in that the composition of the mixture to obtain a pigment containing chromium oxide, zinc oxide, red mud, additionally introduce dolomite, in the following ratio of components, wt.%: Chromium oxide 20-30; zinc oxide 5-10; red mud 25-35; dolomite 35-40.

В таблице приведены составы шихты.The table shows the composition of the charge.

Пигмент получают следующим методом. Компоненты размалывают до прохождения через сетку №0063, дозируют и смешивают. Полученную массу обжигают при 850-950°C в окислительной среде, охлаждают и размалывают до прохождения через сетку №0063.The pigment is obtained by the following method. The components are ground until passing through mesh No. 0063, dosed and mixed. The resulting mass is fired at 850-950 ° C in an oxidizing environment, cooled and ground until passing through mesh No. 0063.
