    Abstract: Method for determining the size concentration, the particle size and the particle size distribution of natural and/or synthetic sizes in a paper stock by staining a sample of the particles (T i ) of the size with a fluorescent dye, light being radiated into the sample of fluorescent or fluorescently stained particles and scattered light and/or fluorescent light from the sample being recorded and evaluated, and use of this method for determining the particle size distribution of reactive size particles in the paper stock or in the white water of paper machines during papermaking.

    Abstract: Emulsifier-free antifoams are obtainable by mixing a) from 80 to 99% by weight of at least one finely divided, virtually water-insoluble, inert solid with b) from 1 to 20% by weight of at least one hydrophobic, organic compound which has an antifoam action and is solid at room temperature in the absence of a solvent in a shear gradient such that the particle size of the compounds (b) which have an antifoam action is reduced to a mean particle size of from 0.5 to 15 mum, emulsifier-free oil-in-water dispersions of mixtures of (a) and (b) are prepared by mixing the component (a) in an amount of from 80 to 99% by weight with the compounds of component (b) in an amount of from 1 to 20% by weight in the absence of emulsifiers in an extruder or kneader in a manner such that the mean particle size of the component (b) in the mixture is brought to 0.5 to 15 mum, at up to 100° C., and emulsifying the mixture in water, and the oil-in-water dispersions thus obtainable are used as antifoams and/or deaerators for aqueous, disperse or nondisperse liquids, in particular as antifoams and/or deaerators in the paper industry, in the food industry and in wastewater treatment plants.

    Abstract: The invention relates to defoaming agents that are devoid of emulsifiers, obtained by mixing: a) between 80 and 99 wt. % of at least one fine-particle d, practically water-insoluble inert solid with b) between 1 and 20 wt. % of at least one hydrophobic organic compound that is solid at room temperature and has a defoaming action in substance with such a shear gradient that the particle size of the defoaming compounds (b) is reduced to an average partic le size of between 0.5 and 15 m. The invention also relates to a method for producing oil-in-water dispersions that are devoid of emulsifiers from mixtures of (a) and (b). Said method involves the mixing of component (a) in a quantity of between 80 and 99 wt. % with component (b) in a quantity of between 1 and 20 wt % in the absence of emulsifiers in an extruder or kneadi ng machine, in such a way that the average particle size of component (b) in th e mixture is regulated to between 0.5 and 15 m, at temperatures of up to 100 ~ C and the subsequent emulsification of the mixture in water. The invention further relates to the use of the oil-in-water dispersions obtained by said method as defoaming agents and/or deaerators of aqueous, disperse or non- disperse liquids, in particular as defoaming agents and/or deaerators in the paper industry, in thefoodstuff industry and in purification plants.
