    摘要: The invention relates to a process for intensifying the surface stabilization of soil susceptible to erosion by introduction of water-based adhesion-promoting impregnating compounds based on esters of polyvinyl alcohol with C.sub.1-5 monocarboxylic acids and mixtures thereof with higher monocarboxylic acids (binders) using surface-active and biologiclly compatible wetting agents. The process is characterized in that impregnation of the soil is carried out in several stages and in that an aqueous preparation containing the wetting agents is used at least in the first impregnating stage. Binder is preferably used in a comparatively small quantity in this pre-impregnation stage.

    摘要: Described is the use of surface-active alpha-sulfofatty acid di-salts as ecologically compatible emulsifiers of the W/O type and O/W type, respectively, in fluid and pumpable drilling fluids and other fluid drilling-hole treatment agents which comprise a continuous or a dispersed oil phase together with an aqueous phase and which are suitable for an environmentally acceptable exploitation of geological resources, for example oil or natural gas deposits. The invention further relates to inverted drilling fluids based on a continuous oil phase and, present therein, a dispersed aqueous phase which, in addition to the emulsifiers, contain further conventional auxiliary agents such as thickeners, fluid-loss additives, weighting agents, water-soluble salts and/or alkali reserves. The inverted drilling fluids according to the invention are characterized in that they contain surface-active di-salts of the type indicated as emulsifier or as an emulsifier component together with an ecologically compatible continuous oil phase.

    摘要: Described is the use of oleophilic monomeric and/or oligomeric diesters of carbonic acid with the same or different oil-soluble and ecologically compatible mono-functional and optionally polyfunctional alcohols as a component of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The invention in one embodiment comprises oil-based fluids, and particularly inverted fluids of the W/O type, which in the continuous phase at least in part contain oleophilic carbonic acid diesters. In a further important embodiment the invention relates to water-based emulsion fluids which in the dispersed oil phase at least in part contain said oleophilic carbonic acid diesters. The invention further comprises drill-hole treatment agents, and especially drilling fluids of the above-mentioned types, the continuous or dispersed oil phases of which, respectively, consist of oleophilic carbonic acid disasters or contain said ester type in admixture with other ecologically compatible oil mixing components. Preferred mixing components for a use in combination which the carbonic acid diesters are appropriate carboxylic acid ester oils, oleophilic alcohols and/or oleophilic ethers.

    摘要: The fiber material (of which a yarn is to be spun) is drawn and combed after carding. In order to determine the combing intensity, a sample is taken from the fiber material after carding and is subjected to an analysis for fiber length and/or impurities. Certain limits are set for fiber length and/or impurities and the combing intensity is adjusted according to the results of the analysis. The fiber material treated with this combing intensity is again drawn and is then opened into individual fibers which are incorporated into a continuously spun and drawn-off yarn.
