    Abstract: A tubular free-fall separator for the electrostatic separation of particles of a plastics mixture, includes two parallel opposite rows of vertical tubes which are either arranged rotatably around their own axis or are fixedly installed and are connected with a direct current voltage source for maintaining an electrostatic field between the rows. The tube rows are arranged in such a manner that two adjacent axis points of the tubes of one row always form a parallelogram, which has no right angles, with the opposite adjacent two axis points of the tubes of the other row.

    Abstract: The present invention relates to a method for the production of coated magnesium hydroxide particles, whereby the individual primary magnesium hydroxide particles are coated. According to the invention, specific additives are added to the precipitation reaction for obtaining the magnesium hydroxide particles, in order to obtain these magnesium hydroxide particles in a coated state. Furthermore, a first method step of the present invention is directed at a method for the production of coarse-scale or nanoscale, coated magnesium hydroxide suspensions or dispersions. In a second method step, the coated magnesium hydroxide particles can be converted to de-agglomerated products either by means of bead-mill grinding or ultrasound and a dispersant. Finally, the present invention is directed at coated magnesium hydroxide particles, particularly nanoscale, coated magnesium hydroxide particles that can be obtained in this manner.

    Abstract: The present invention relates to a method for the production of curable masses, containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles. More precisely, the present invention relates to a method for the production of curable masses, whereby coarse-scale and/or nanoscale, precoated magnesium hydroxide particles in an aqueous or organic solvent are treated with ultrasound or subjected to bead-mill grinding in the presence of a dispersant. After any drying that might be necessary, and renewed suspension/dispersion in an organic solvent, the magnesium hydroxide particles are worked into a component of a curable mass. Furthermore, the present invention is directed at a method for the production of a cured polymer material. Finally, the present invention makes available curable masses, polymer materials produced from them, particularly duroplastics or thermoplastics, as well as composite material containing curable masses or polymer materials produced according to the invention, as well as reinforcement agents.
