PROBLEM TO BE SOLVED: To provide a spray nozzle capable of promoting atomization of a fluid to be sprayed while reducing a pressure and the use amount of a spraying medium.SOLUTION: A spray nozzle according to the present invention comprises: at least two sprayed fluid flow channels in which a fluid to be sprayed flows; at least two spraying medium channels, in which a spraying medium flows, and each of which joins each of the sprayed fluid channels at a first confluence; at least two mixed fluid channels, in which a mixed fluid of the fluid to be sprayed and the spraying fluid that have joined at each of the first confluences flows, which is formed so as to face each other to make opposing flows of the mixed fluid, and which have a second confluence at which the mixed fluids collide with each other and join; and an outlet hole from which the mixed fluid joined at the second confluence is sprayed. A bent portion, at which the flow direction of the mixed fluid is changed, is formed between the first confluence and the second confluence in the mixed fluid channel.
Abstract:
An air cap for keeping a spray nozzle with a flat spray clean is presented. The air cap contain the nozzle and has a slit for the spray from the nozzle, through which opening an air flow is flowing in the same direction as the flat spray from the nozzle. The air cap is divided into a back component comprising an internal thread, and a front component comprising the slit. The components are rotatable relative to one another.
Abstract:
As a wrist portion of an application robot equipped with a plurality of application nozzles moves in a predetermined operation pattern, viscous damping and constraining materials having different properties are simultaneously injected from the application nozzles so that immediately after the damping material is injected from the preceding application nozzle, as viewed in the moving direction and applied to a vehicle body panel as an underlayer material, the constraining material having different property is injected from the succeeding application nozzle, as viewed in the moving direction, and applied as an overlayer material over the underlayer material.
Abstract:
PROBLEM TO BE SOLVED: To provide a two-fluid slit nozzle for spraying by providing with a mixing space in which two fluids collide at right angles each other in a slit nozzle in order to obtain a film-like spray mist homogeneous in the longitudinal direction by mixing a liquid with a gas, and passing through a means for further homogenizing the mixture fluid. SOLUTION: A mixing plate is inserted to be held between a long platy liquid feeding plate and a gas feeding plate. A liquid which is fed through a liquid orifice penetrated through a mixing plate from the liquid feeding plate is collided to mix with air in a mixing space on another face of the mixing plate, the air being fed through an air orifice from one air feeding plate to the other face of the mixing plate. The film of spray mist is sprayed from a spray slit by communicating the downstream end of the mixing space and the upstream end of the spray slit between the lower end faces of both of the mixing and air feeding plates by a colliding chamber for conducting homogenization and acceleration by expanding and compressing formed by connecting two groups of orifices penetrating through the mixing plate at the side of the liquid feeding plate between the two groups of orifices.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing an inkjet recording medium, which is high in quality, can efficiently and stably be applied at a high speed hardly causing coating failure such as liquid splashing, flake-like unevenness or crack without causing the problem such as coagulation or deposition in the method of obtaining the inkjet recording medium by applying a layer containing an additive (referred to as a functional layer hereafter) on a substrate having a coating layer. SOLUTION: This method for manufacturing the inkjet recording medium by conveying an object to be coated and applying an overcoat layer by a spray coating device is characterized in that the displacement of the position of the object in an overcoat layer coating part is defined as ≤0.5% of a coating width in uncoating time and coating time.
