Abstract
Изобретение относитс к области производства пигментов, а именно к технологии получени оксида цинка, который используетс в качестве пигмента . Целью изобретени вл етс увеличение содержани основного вещества в оксиде цинка и снижение в нем водорастворенных солей и хлора. Способ получени оксида цинка состоит в следующем. Соль цинка, например хлорид или сульфат цинка, обрабатывают бикарбонатом аммони в количестве 2,0- 10,0% от содержани соли с последующим взаимодействием полученной пульпы с гидроксидом натри при 50-90 с, образовавшуюс при этом суспензию фильтруют, промьшают, сушат и прокаливают . Полученный продукт содержит 98,0-98,4 мас.% соединений цинка в пересчете на ZnO, водорастворимых веществ 0,26-0,32 мас.% (из сульфата цинка) и соответственно 99,0-99,3 tft и 0,06-0,15 мас.% дл продукта, полу- ченного из хлорида цинка при Содержании хлорида О,033-0,040%.2 з.п.ф-лы, 1 табл. (Л сThe invention relates to the production of pigments, in particular, to the technology for producing zinc oxide, which is used as a pigment. The aim of the invention is to increase the content of the main substance in zinc oxide and decrease in it water-soluble salts and chlorine. The method for producing zinc oxide is as follows. Zinc salt, for example, zinc chloride or zinc sulfate, is treated with ammonium bicarbonate in an amount of 2.0-10.0% of the salt content, followed by reacting the resulting pulp with sodium hydroxide at 50-90 seconds, the suspension thus formed is filtered, washed, dried and calcined . The resulting product contains 98.0-98.4 wt.% Zinc compounds in terms of ZnO, water-soluble substances of 0.26-0.32 wt.% (From zinc sulfate) and respectively 99.0-99.3 tft and 0, 06-0.15 wt.% For the product obtained from zinc chloride with the content of chloride O, 033-0.040% .2 cpfl, 1 tab.
