Изобретение относитс к производству пигментов - цинковых кронов.The invention relates to the production of pigments - zinc crowns.
Известный способ получени пигментов - цинковых KipOHOB заключаетс во взаимодействии цинковых белил и хромового ангидрида при соотношении Т : Ж не 1:4.A known method for producing zinc KipOHOB pigments consists in the interaction of zinc white and chromic anhydride with a T: W ratio of 1: 4.
Недостатком известного способа вл етс довольно высока влагоемкость пигментной пасты - 60-70%, затрудн к ща процесс сушки пигмента.The disadvantage of this method is the rather high moisture capacity of the pigment paste — 60-70%, making it difficult for the pigment to be dried.
Предлагаемый способ отличаетс от известного тем, что взаимодействие ведут в присутствии фосфорной кислоты, вводимой в количестве не 0,2%.The proposed method differs from the known one in that the reaction is carried out in the presence of phosphoric acid, which is not added in an amount of 0.2%.
Указанное отличие обеспечивает снижение влагоемкостц пигментной пасты до 40%, что значительно сокращает процесс сушки, увеличивает производительность сушильного оборЗдовани в 10 раз и производительность реактора синтеза в 1,5 раза за счет уменьшени разведени .This difference ensures a reduction in the moisture capacity of the pigment paste up to 40%, which significantly reduces the drying process, increases the productivity of the drying equipment by 10 times and the productivity of the synthesis reactor by 1.5 times due to a decrease in dilution.
Пример:Example:
В воду перед загрузкой цинковых белпл добавл ют фосфорную кислоту (НзРО4) в количестве 0,01-0,2% в зависимости от заданного содержани влаги в пасте, затем производ тс обычные операции синтеза цинкового крона: пропаривание белил, слив раствора хромового ангидрида, перемешивание, фильтрацию и сушку пигмента.Phosphoric acid (H3PO4) in an amount of 0.01–0.2% is added to the water before loading the zinc protein, depending on the specified moisture content in the paste, then the usual operations of zinc crown synthesis are performed: steaming the white, draining the chromic anhydride solution, mixing , filtering and drying the pigment.
Зависимость характеристики цинкового крона от количества вводимой фосфорной кислоты приведена в таблицеThe dependence of the characteristics of the zinc crown on the amount of phosphoric acid is given in the table
