Abstract
Sposób otrzymywania otoczkowanego nawozu według wynalazku polega na tym, że: granulowy nawóz miesza się i wygrzewa przez 2-6 h w temperaturze 50-80°C z warstwą hydrofobową zawierającą tłuszcz roślinny lub zwierzęcy, posiadający wiązania nienasycone w cząsteczce, modyfikowany solą kobaltową i/lub manganową wyższych kwasów organicznych, otrzymaną poprzez wymieszanie tłuszczu i soli kobaltowej i/lub manganowej kwasu 2-etyloheksanowego w proporcji wagowej 10:1 - 20:1, i/lub do granulowanego nawozu w temperaturze minimum 50°C, powoli stosując nadmuch gazu inertnego, wprowadza się metodą natryskową warstwę polimerową zawierającą: - octan celulozy, - i/lub ftalan octanu celulozy, - i/lub octanomaślan celulozy lub ich mieszaninę.The method of obtaining the coated fertilizer according to the invention consists in that: the granular fertilizer is mixed and heated for 2-6 h at a temperature of 50-80 ° C with a hydrophobic layer containing vegetable or animal fat, having unsaturated bonds in the molecule, modified with cobalt salt and / or manganese of higher organic acids, obtained by mixing fat and cobalt and / or manganese salts of 2-ethylhexanoic acid in a weight ratio of 10: 1 - 20: 1, and / or to granulated fertilizer at a temperature of at least 50 ° C, slowly applying an inert gas blow, a polymer layer is applied by spraying, comprising: - cellulose acetate, - and / or cellulose acetate phthalate, - and / or cellulose acetate butyrate or a mixture thereof.
