FIELD: building materials industry.
SUBSTANCE: invention relates to building materials industry, namely to the production of mineral wool insulator. The technical result is achieved due to the fact that after the polymerization procedure, the formed mineral wool plates are placed in a closed resonant microwave chamber, where they are processed with microwave radiation with a frequency of 1450 MHz and a power of at least 60 kW for 15-40 seconds.
EFFECT: eliminates the defects in mineral wool plates and quality improvement of produced mineral wool insulator.
