摘要： The invention relates to a process for making striking surfaces wherein red phosphorus, abrasive agents, and binders which are in the form of aqueous urea/formaldehyde or melamine/formaldehyde-condensates, are made into an aqueous suspension which is applied on to a striking surface substrate. More particularly, the suspension, based on the solid matter content of the condensates used as binder, is admixed with 5 to 20 weight %, calculated as solid matter, of an agent cross-linking the amine resin, the cross-linking agent being a polyester or copolymer produced by subjecting an acryl and/or methacryl ester to copolymerization with vinyl acetate in a ratio by weight of 1:9 to 9:1. A pH-value within the range 6.5 to 8.0 is established in the mixture, in the event of the cross-linking agent being a copolymer, or a pH-value within the range 7 to 11 is established, in the event of the cross-linking agent being a polyester.

摘要： A mixture of mercury and red phosphorus obtained by flowing an aqueous solution having at least one mercury salt dissolved in it through a layer of granular red phosphorus in a column arranged in upright position and provided, close to its lower end, with means supporting the layer of red phosphorus, is separated into its constituents. To this end, fluidizing matter is forced from below under pressure over a period of 5-30 minutes through the said means and layer of red phosphorus thereon, the mercury/red phosphorus-mixture covered with solution and provided with flow deflecting paths becoming lifted up; mercury dropping from the mixture so lifted is collected over a period of 5-30 minutes on the supporting means; fluidizing matter is forced from above under pressure over a period of 1-20 seconds into contact with the said mixture; and the mercury running down from the supporting means is collected. Apparatus for carrying out the process.

摘要： Dimensionally stable alkaline cleansing agents of low density consist at least of 2 to 50% by weight of alkali metal phosphates, 2 to 50% by weight of silicates and 1 to 60% by weight of alkali metal hydroxides and/or alkali metal carbonates or bicarbonates and additionally contain 0.25 to 10% by weight of phosphoric acid partial esters.These cleansing agents are prepared by first foaming phosphoric acid partial esters with water in a weight ratio of (1:2) to (1:80), using intensive stirring. When the remaining components have been incorporated into the foam, using stirring or kneading, the resulting mixture is converted to moldings. The moldings are allowed to set for 0.5 to 15 hours.
