Title:
繊維組成物の吹付け方法
Document Type and Number:
Japanese Patent JP7457219
Kind Code:
B2
Abstract:
To provide a technique to allow for estimating that residence and pulsation of fine particles of fibers do not easily occur when starting or during construction and a technique capable of improving workability by preventing the residence and pulsation of fine particles of fibers from occurring in a fiber composition spraying method by a dry construction method or semi-dry construction method.SOLUTION: In a fiber composition spraying method, fibers of a predetermined amount are supplied into a fiber pressure feed passage; the fibers are 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 fibers and the liquid additive to a coating object. When starting to spray the merged and mixed material, pressure in the fiber pressure feed passage during air pumping of the fibers is checked.SELECTED DRAWING: Figure 1
