HEAT-INSULATING PRODUCT BASED ON MINERAL WOOL AND METHOD FOR OBTAINING PRODUCT Russian patent published in 2022 - IPC D04H5/12 D04H3/02

Abstract RU 2764087 C2

FIELD: heat insulation.

SUBSTANCE: invention relates to a method for producing a heat-insulating product based on mineral wool. The method includes obtaining mineral fibers by internal centrifugation, receiving mineral fibers on a belt of a receiving conveyor with a speed V₀, delivering mineral fibers to the first conveyor group, wherein speed V₁ of the last conveyor of the first conveyor group is from 100% to 105% of V₀, delivering mineral fibers to the second conveyor group, wherein speed V₂ of the last conveyor of the second conveyor group is from 108% to 120% of V₀, preferably from 110% to 115% of V₀.

EFFECT: invention allows for obtaining products with high heat-conductivity at reasonable thickness.
