METHOD FOR DETERMINING OPTIMAL PARAMETERS OF PRESSING PRESSURE AND MOULDING POWDER MOISTURE FOR PRODUCING CERAMIC WALL MATERIALS Russian patent published in 2016 - IPC G01N33/38 G01N3/08 

FIELD: construction.

SUBSTANCE: invention relates to production of construction materials. Method involves preparation of moulding powder, pressing of the sample, fixation of deformation changes during compression, constructing compression curves and testing, pressing is performed in one stage and continuously, with variable pressing pressure values and moulding powder moisture, required optimal moisture and pressing pressure ratio is determined by position of the optimum point at the compression curve, located at its intersection with a segment, which is perpendicular to the chord connecting the initial and final pressure interval value on the curve, and passing through the point of intersection of tangents to the curve in the area of the given pressure interval.

EFFECT: possibility to define optimum values of pressing pressure and moulding powder moisture with minimum amount of experiments.
