    摘要： The invention relates to sodium perborate hydrate granulates and a method for producing sodium perborate hydrate granulates with an available oxygen content of 14 to 18% by weight, especially 15 to 16% by weight; an abrasion index according to ISO test 5937 of not more than 10%; with a rate of dissolution of below 1.5 minutes, preferably below 1.0 minutes (for 1 gram of the granulate in 500 cm.sup.3 water, at 15.degree. C.); and with a bulk weight in the range of 0.6 to 1.2 kg/dm.sup.3. The sodium perborate hydrate granulate can be produced by compacting spray-dried, essentially amorphous sodium perborate hydrate starting material which exhibits a bulk weight below that of the granulate product, and a particle size of 90% less than 100 micrometers. The hydrate starting material is further characterized in that it loses 0.2 to 2.0% of its weight when stored at 60.degree. C. and 100 Pa for 30 minutes. The starting material is compacted between rollers at a contact pressure of 5.times.10 to 2.times.10.sup.4 N/cm, and the resultant product is comminuted and the granulate is sieved according to particle size. The compacted granulate particles may be rounded off by means of a mechanical stressing prior to the sieving step. This method produces granulates with the above-mentioned characteristics which are desired in the market. The granulates are produced in a simple manner, without thermal stressing of the perborate.

    摘要： The spray drying of a solution containing hydrogen peroxide and sodium metaborate to obtain primary particles which are immediately conveyed after leaving the drying zone to a granulating device and are then granulated in the presence of free and/or perborate water of crystallization. The granulated materials are dried, if necessary. The generally amorphous primary particles are converted into granulated materials with at least partially crystalline structure and significantly improved shelf life. The work is performed with advantage in a spray dryer with integrated fluid bed or in a compressing granulating device. The method is suitable for preparing perborate granulated materials with an active oxygen content of over 10% by weight, especially perborate monohydrate granular materials with 14 to 16% by weight active oxygen. A rapidly dissolving product is produced with an acceptable apparent weight for ease in packaging.

    摘要： Sodium percarbonate is often used in the form of coated particles to increase its storage stability in detergents.Sodium percarbonate particles coated in accordance with the invention have a coating containing reaction products from the reaction of a dialkali metal tetraborate or alkali metal pentaborate with aqueous hydrogen peroxide. Preferred coating components are: perborax with the formula Na.sub.2 B.sub.4 O.sub.7 .multidot.H.sub.2 O.sub.2, where n =2 or 4.The coated sodium percarbonate particles are produced by coating the percarbonate particles using a solution containing the reaction products mentioned above.Detergent, bleaching and cleaning compositions containing sodium percarbonate particles coated in accordance with the invention are distinguished by very high stability in storage.

    摘要： The invention relates to a method for increasing the storage stability of sodium percarbonate (2 Na.sub.2 CO.sub.3.3 H.sub.2 O.sub.2) by coating with a sodium perborate.According to the present invention wet sodium percarbonate salt, obtained by reacting sodium carbonate with hydrogen peroxide in aqueous phase and separating the salt from the aqueous phase, is treated with a solution or suspension containing sodium perborate in a solid-liquid separator by a kind of displacement wash. In contrast to previously known methods, according to the present invention a greater storage stability is attained with smaller quantities of perborate coating.
