Title:
繊維組成物の吹付け方法
Document Type and Number:
Japanese Patent JP7457218
Kind Code:
B2
Abstract:
To provide a technique to allow for estimating that absolute dry bulk density of a fiber layer to be formed is within a predetermined range during construction and a technique to make the absolute dry bulk density of the fiber layer formed by construction fall within a predetermined range in a fiber composition spraying method by a dry construction method or semi-dry construction method.SOLUTION: In a fiber composition spraying method, fiber or fiber dry composition of a predetermined amount is supplied into a fiber pressure feed passage; the fiber or the fiber dry composition is air-pumped by supplying a predetermined amount of air into the fiber pressure feed passage using an air blower and subsequently discharged from a fiber discharge port; a liquid additive is injected from one or a plurality of liquid additive injection ports provided either on an outer periphery or inside of the fiber discharge port or in the fiber pressure feed passage within 1 m from the fiber discharge port so as to spray a merged and mixed material obtained by merging and mixing the fiber or the fiber dry composition and the liquid additive to a coating object. The merged and mixed material is sprayed while checking the pressure in the fiber pressure feed passage during air pumping of the fiber or the fiber dry composition.SELECTED DRAWING: Figure 1
