FIELD: chemistry.
SUBSTANCE: hollow cylinder is filled and a hydrophobisated fraction of ammonium perchlorate is poured out of it. The hollow cylinder with diametre of 40 mm and height of 100 mm is placed with its axis at the centre of a plate with diametre of 250 mm. On the plate there are marking circles with diametre ranging from 100 mm to 200 mm every 10 mm from the centre. Fluidity is determined from the average diametre of the edge of the hydrophobisated fraction of ammonium perchlorate dispersed into a circle.
EFFECT: design of a rapid method for determining fluidity, creating conditions for continuous preparation of a hydrophobisated fraction of ammonium perchlorate.
