20190048264 · 2019-02-14 ·

A process for the manufacturing of fire suppressing crystals having a high Q-factor particle size distribution, said fire suppression crystals being intended for use as a fire suppressing additive in polymer compositions, the process comprising the steps; a) Preparing a mother liquor comprising water and a salt composition obtained in step c) or d), the temperature of said mother liquor being adjusted to 10-50 C. and comprising said salt composition to a level of at least 90% of saturation. Calcium hydroxide is added to the mother liquor to a level of at least 90% of saturation. b) Preparing an acid solution comprising water and two or more acids selected from the group consisting of; C.sub.2-C.sub.6 mono-, di- and/or tri-carboxylic acids, and optionally a phosphorous compound. The temperature of said acid solution is adjusted to 20-90 C. 31 and comprising acids to a level of at least 50% of saturation. c) The mother liquor, comprising calcium hydroxide, obtained from step a) is subjected to intense agitation under which the acid solution obtained from step b) is slowly added to said mother liquor allowing reaction to form salt until supersaturation is achieved while maintaining PH at a level securing that no unreacted acids remains after reaction, d) Crystals formed in the reaction of step c) is continuously or discontinuously removed from the reaction product of step c).
