摘要:
Phytosanitary composition for use especially in affording protection to plants from undesirable plant species. The composition is characterized in that it contains at least one benzamidic compound associated with at least one cyclodextrine to improve mobility in the ground and/or the biological afficacy of the benzamidic derivative. The invention also concerns a method of preparing the phytosanitary composition.
摘要:
Disclosed is a thermoformable composition characterized in that it contains at least one starchy compound, at least one biodegradable polyester and at least one salt of hydroxycarboxylic acid.
摘要:
Phytosanitary composition, useful particularly for the protection of plants against crypotogamic diseases, characterized in that it contains a source of Cu.sup.++ copper ions and at least one cyclodextrin adapted to form complexes with said copper ions.
摘要:
Wet-end cationic additive for the manufacture of paper, comprising a mixture of at least one cationic cereal starch and at least one cationic tuber starch.
摘要:
A process for manufacturing paper is characterized by the fact that there is introduced into the fibrous composition constituting the starting or raw material, at two or several points, particularly in the wet end, separately from one another, one (or several) cationic starch(es) and one (or several) anionic starch(es) other than a starch phosphate.
摘要:
The invention relates to a coating composition for paper and cardboard comprising, besides the usual pigments, a fluidizing agent and, by way of binder, an undepolymerized starch possibly modified, as well as, generally, one or several synthetic products and/or one or several proteins.
摘要:
The present invention relates to an aqueous dispersion of pigment(s) and/or filler(s) containing, as an additive, a saccharide composition containing at least 30% of hydrogentated monosaccharide(s) and/or disaccharide(s). The saccharide composition contains at least 75% of such saccharides, in particular sorbitol, mannitol and/or maltitol. The optimum introduction rate is somewhere between 1 and 3%, in dry weight in relation to the dry weight of pigment(s) and filler(s) of the dispersion. The dispersion according to the invention presents a Brookfield viscosity (20° C., 20 rpm) of between 100 and 4000 mPa.s and a viscosity instability index lower than 35%. The dispersion according to the invention can present a very high level of solid matter, for example from 72 to 80% and be used advantageously in numerous industries such as those connected with paper, paint and varnishes, inks, adhesives, detergents, textile materials and leathers, etc. The dispersion can contain various pigments or fillers such as clays (kaolins, smectites), calcium carbonates, talc, titanium dioxide, calcium or barium sulphates or sulfoaluminates.
摘要:
An aqueous machining fluid including at least one fatty substance, at least one cyclodextrin and water is disclosed. Also disclosed is a process for making such machining fluid and a process for using the machining fluid to process workpieces, particularly metal pieces, by means of said aqueous machining fluids.
摘要:
Amylaceous composition of mixtures based on synthetic or natural binders or compounds employed in the manufacture of certain textile or paratextile products and particularly of the composite textile type. It comprises:from 7% to 45% by weight, preferably from 10% to 25% by weight, of a starch swelling in cold water, if necessary modified chemically,from 55% to 93% by weight, preferably from 70% to 85% by weight, of granular starch, modified chemically.
