Title:

SPRAYING DEVICE, SPRAYING METHOD AND UNDETERMINATE FORM FIRE-RESISTANT MATERIAL

Document Type and Number:

Japanese Patent JP2007152237

Kind Code:

A

Abstract:

To provide a spraying device capable of preventing the occurrence of rebound loss and dust while suppressing supplied applying water to a small amount.

An undeterminate form fire-resistant material 10 and a gas to be transferred are supplied to a transferring hose 1 by a powdery material supply vessel 7. The undeterminate form fire-resistant material 10 is transferred by air-flow toward a spraying nozzle 3 through the transferring hose 1. The applying water is atomized by an applying water supply vessel 6 installed on the way of the transferring hose 1 to the transferring hose 1. The transferring hose 1 from the powdery material supply vessel 7 to the applying water supply vessel 6 is constituted of a material making the undeterminate material 10 charge by friction to positive, while an electrode for charging making the applying water charge by electrostatic phenomenon is installed in the applying water supply vessel 6.
