A method for adjusting the amount of dilution water of a sizing composition, and a corresponding calculation unit

摘要

The present invention relates to a method for producing a mat of mineral fibers (F), wherein the fibers (F) are formed, a sizing composition obtained from a mixture of a binder composition and diluent water is applied to the fibers (F), the sizing composition comprising: The impregnated fibers are collected on an open-working receiving device 52 having a fiber receiving surface and at least one suction sheath 54 below the surface, and the mat is heat treated. The method according to the invention requires the humidity of the air on the fiberizing station ( 12 ), the humidity of the incoming air into the at least one intake sheath ( 54 ) and the incoming air flow, and the mat at the outlet of the receiving chamber ( 50 ). determining an optimal amount of the dilution water according to the amount of water to be used, and adjusting the amount of the dilution water according to the optimal amount so determined.
