摘要:
The invention relates to a new solid storage and marketing presentation for phytosanitary compositions based on any active substance which is little soluble in water or insoluble in water and solid at ambient temperature; these active substances are especially selected from herbicides presenting the said features; these herbicides comprise bramoxynil, ioxynil and their esters as well as. dinitroanilines, especially butralin, pendimethalin, flumetralin and oryzalin. It is in the form of flakes based on a film-forming material which is water-soluble and brittle after drying, and throughout which are dispersed especially the particles of active material. This solid storage and marketing presentation may be prepared by maly of an installation comprising a rotating drying drum (1) on which a thin layer of a dispersion (D) of particles of active substance in an aqueous solution of a film-forming material which is brittle at the dry state is applied. The parties of the surface of the drum on which is applied the dispersion (D) travel through the heated part or zone of the chamber (2) at a speed such that the dispersion is dried, shrinks and becomes detached fromthe surface of the drum (1) in forming flakes (P).

摘要:
Granular herbicidal water-soluble composition based either on aminotriazole alone or on aminotriazole combined with at least one other herbicide selected from the group comprising alkaline, alkaline-earth metal and ammonium thiocyanates, glyphosate, MCPA sodium salt, sulfosate, glufosinate, paraquat and metribuzen. It is provided in the form of granules of cylindrical shape, with a composition and a diameter which are substantially identical from one granule of cylindrical shape to another for a given granular herbicidal composition, the diameter and the length of the said granules of cylindrical shape being respectively of the order of 0.4 to 2 mm, preferably of 0.8 to 1.4 mm, and of the order of 5 to 10 millimeters. The said granular herbicidal composition is obtainable by use of a process according to which aminotriazole, alone or as an intimate homogeneous mixture with at least one other herbicide of the above-identified group, is, if necessary, brought by milling to a suitable particle size, mixed with an amount of water sufficient to ensure its cohesion under a moderate pressure, optionally brought together with a surface-active agent and directed through the orifices of the grid of an extrusion device, the granules of cylindrical shape thus obtained being dried.

摘要:
The invention concerns the use of a composition or premix based on volatile corrosion inhibitors comprising, in order to limit to a maximum the release and/or degradation of the volatile corrosion inhibitors when the composition or premix is being formed, either an efficient amount of a structuring agent consisting of at least one solid or pasty substance whereof the melting point ranges from 40 to 110° C. preferably from 50 to 90° C., or a liquid substance capable of forming, mixed with a mineral filler, a solid or pasty combination. The invention also concerns a composition based on volatile corrosion inhibitors comprising a composition based on volatile corrosion inhibitors comprising an efficient amount which contains an efficient amount of a solid structuring agent. The invention further concerns polymer based articles having as constituent said composition or premix; said article are useful for protecting metal parts against corrosion.
