Изобретение относитс к технологии получени неслеживающегос хлористого кали .This invention relates to a process for the production of non-caking potassium chloride.
Известен состав дл предотвращени слеживаемости минеральных солей, состо щий из неорганического материала и гидрофобного реагента, в качестве неорганического соединени используют тальк в количестве 0,450 кг/т удобрени , в качестве гидрофобного реагента - стеариламин в количестве 0,550 кг/т удобрени м.A composition for preventing caking of mineral salts, consisting of an inorganic material and a hydrophobic reagent, is known; talc in an amount of 0.450 kg / ton of fertilizer is used as an inorganic compound, and 0.550 kg / ton of fertilizer is used as a hydrophobic reagent.
Недостатком известного состава вл ютс недостаточно высокие показатели слеживаемости.A disadvantage of the known composition is not sufficiently high caking performance.
Целью изобретени вл етс устранение слеживаемости хлористого кали . Поставленна цель достигаетс обработкой хлористого кали описываемьо|1 составом дл снижени слеживаемости на основе фобного реагента и неорганического соединени .The aim of the invention is to eliminate caking of potassium chloride. This goal is achieved by treating potassium chloride with the composition 1 to reduce caking based on a fob reagent and an inorganic compound.
Существенным отличием предлагаемого состава вл ютс его компоненты и их количества.The essential difference of the proposed composition is its components and their quantities.
Использование предлагаемого состава , дл уменьшени слеживаемости 5слористого -кали значительно снижает гигроскопичность соли, а также ее токсичность.The use of the proposed composition to reduce caking of 5-hydrochloride significantly reduces the hygroscopicity of the salt, as well as its toxicity.
Обработанный составом образец хлористого кали провер ют на слеживаемость . Показателем слеживаемости служит глубина погружени режущего органа бура в спрессованный образец КС . Образцы КС В предварительно выдерживают в течение 18 ч в термостате при температуре 60°С и давлении на образец 0,17 кг/см.A sample of potassium chloride treated with the composition is checked for caking. An indicator of caking is the immersion depth of the cutting organ of the drill in a compressed CS sample. Samples KS B are pre-incubated for 18 hours in a thermostat at a temperature of 60 ° C and pressure on the sample of 0.17 kg / cm.
О Результаты испытаний приведены в таблице.О The test results are shown in the table.
Как видно из таблицы сравнительных испытаний, применение- алкилнафталинаAs can be seen from the table of comparative tests, the use of alkylnaphthalene
15 и фосфоритной муки повышает показатель слеживаемости дл хлористого кали по отношению к хлористому калию, обработанному амином, в 1,1-1,3 раза .15 and phosphate flour increases the caking rate for potassium chloride in relation to potassium chloride treated with amine, 1.1-1.3 times.
Предлагаемые количества добавок (фосфоритна мука и алкилнафталин) и их соотношени вл ютс оптимальными , так как обеспечивают необходимуюThe proposed amounts of additives (phosphorus flour and alkylnaphthalene) and their ratios are optimal because they provide the necessary
25 гидрофобность поверхности кристаллов хлористого кали , что приводит к снижению гигроскопичности соли.25 hydrophobicity of the surface of potassium chloride crystals, which leads to a decrease in the hygroscopicity of the salt.
Увеличение добавок фосфоритной муки и с1Л кил нафталина не снижает слежи30 ваемость удобрени , однако возрастаетAn increase in the addition of phosphate flour and S1L kil naphthalene does not reduce the tracking30 fertilizer yield, but increases
его стоимость, в св зи с чем пов1ашать верхние пределы нецелесообразно. Снижение нижних пределов добавок не обеспечивает необходимую гид офобность поверхности кристаллов хлористого кали .its value, in connection with which, it is impractical to lower the upper limits. Reducing the lower limits of additives does not provide the necessary guide of the surface topobicity of potassium chloride crystals.
