FIELD: construction; acoustics.
SUBSTANCE: invention relates to production of acoustic ceiling tiles based on mineral wool. Method of producing diluted aqueous suspension for water hardening of main mat for acoustic ceiling tiles, includes delivery of a bale of pressed mineral wool with density of at least 8 pounds per cubic foot (approximately 0.13 g/cm3) on section for unpacking bales, disconnection of attachment holding bale in compressed state, mechanical separation of fibres from bale of mineral wool by mechanical means arranged with possibility of dispersion of fibres to ensure overall uniform density of less than 2 pounds per cubic foot (approximately 0.032 g/cm3), until passage of fibres via inlet of tank and direction of separated mineral fibre into mixing tank for bringing into contact with binding agent suspended in water.
EFFECT: technical result consists in improvement of acoustic characteristics, high mechanical properties of tiles.
