摘要:
The present invention relates to granules of water-soluble, hygroscopic products having a mean grain size in the range from 200 to 2000 .mu.m, the granule grains consisting of an agglomerate of fine product particles having a mean particle size in the range from 5 to 200 .mu.m, which are covered with a product layer.
摘要:
The present invention relates to a method for producing granules comprising a pesticide, comprising the spraying-on of a pesticide-containing spray liquid in the region of a near-circular gas/material stream of a spouted-bed apparatus onto the particle surface of the material, and the drying and granulation in the gas stream. Furthermore, the invention relates to granules comprising a pesticide, obtainable by said method, where the granules have a roundness of at least 0.85.

An essentially anhydrous dithiocarbamate liquid formulation comprises: a) 10 to 70% by weight of at least one active ingredient from the class of the dithiocarbamates, b) 10 to 89% by weight of an essentially anhydrous oil phase, c) 1 to 40% by weight of a polyhydroxystearic acid or a derivative thereof and/or an alkyl or alkenyl glycerin ether ethoxylate, d) 0 to 40% by weight of at least one anionic surfactant.
摘要:
The present invention relates to compositions based on a homogeneous, aqueous phase comprising at least one active ingredient from the class of the quaternized compounds, ethylene oxide/propylene oxide block copolymers and ammonium nitrate. Further active ingredients can be incorporated. The homogeneous phase is stabilized by ammonium nitrate. The use of the compositions as bioregulators is described.
摘要:
An apparatus and a method of effecting the separation of paramagnetic particles from non-paramagnetic particles in the fine and finest particle size ranges of approximately below 1 mm suspended in a fluid medium by the passage of the fluid medium through an apparatus having a separation channel suitable for containing a flow of the fluid medium flowing therethrough and which includes at least two exits suitable for separating the paramagnetic particle enriched fluid medium from the paramagnetic particles depleted fluid medium into two product streams, the separation channel defining the direction of the fluid medium flow being at least partially paralleledly oriented with respect to a magnetic induction member such that the magnetic flux exerted upon the paramagnetic particles within the fluid medium flow are repulsed from the induction member and entrained within the fluid medium to countereffect the effect of inertial forces or gravitational forces on the fluid flow, and separated from the non-paramagnetic particles within the fluid medium flow which succumb to the effect of the inertial forces of gravitational forces and are separated from the paramagnetic particles within the fluid medium flow. In a preferred embodiment of the invention, the induction members are oriented below their associated separation channels at right angles with respect to the lines of magnetic flux, and the separation channels are inclined with respect to the horizontal, so that gravitational forces acting upon the paramagnetic particles contained within the fluid medium are countereffected by the repulsive forces exerted on the same paramagnetic particles by the induction members.
