porous vegetable filler, micronized, sparse, controlled granulometry and specific weak and hydraulic surfaces, preparation process and use.

摘要

The present invention, WHILE NEW INDUSTRIAL PRODUCT, INCLUDES A porous vegetable filler, micronized sparse, particle size Meager SURFACES CONTROLLED AND SPECIFIC physical and hydraulic. This charge PLANT IS DEFINED BY ITS (1) content less RESIDUAL MOISTURE 20% and preferably less than 15%, PRESENTS (1A) grain size D SUB 95 less than 200 microns (THAT IS AT LEAST 95% BY WEIGHT OF pARTICLE said load VEGETAL pass through a mesh screen SQUARE with an aperture of 200 X 200 micrometres) (1B) a surface area less than 2 m PHYSICS (squared) / G, (1C) a specific surface HYDRAULIC LOWER A 2 M (squared) / G, Y (1D) density lower than 500 kg / M (squared) and preferably less than or equal to 300 kg / HIGH 3; and (2) has been obtained by grinding-micronization A less than 150 CY preferably at a temperature not exceeding 100 C. TEMPERATURE IS THIS PLANT CHARGING MICRONIZED UTIL IN THE FIELD OF PASTA, paper, cardboard and non-woven ONE PART, AND FIELD OF COMPOUND PAINT , COATINGS AND BUILDING MATERIALS otherwise.
