A device for detecting and replenishing a salt solution in a salt spray machine and the salt spray machine includes a salt solution collector installed at the bottom of the salt spray machine and configured to collect the salt solution, a return pipe is connected to the salt solution collector and the salt solution storage tank, and a pH value sensor, a water level sensor and the salt concentration sensor are connected to the salt solution storage tank.

A method of reinforcing a support mat includes at least one extruder applying at least a first stream of weld-forming material over at least one seam formed between upper and lower, interconnected, at least partially overlapping, panels on the top of the mat and at least one automated extruder applying at least a second stream of weld-forming material over at least one seam formed between the panels on the bottom of the mat.

An alignment film coating machine and a coating method are provided. The alignment film coating machine includes an equipment for carrying a substrate, a spray head for spraying PI droplets, and an air knife disposed on the equipment and located on one side of the spray head. The air knife is used for moving along the equipment and blowing uniform impact air curtain to the PI droplets after the spray head sprays the PI droplets on the substrate. By adding the air knife into the alignment film coating machine, the diffusion ability of the PI droplets is improved due to the uniform impact air curtain blown by the air knife. The resistance in diffusion is overcome. The PI droplets enter the via hole. Mura, which is induced by a relatively thicker PI film around the via hole as a result of the accumulation of the PI droplets, is prevented.

An applicator for a coating product comprising printing nozzles, each including an outlet channel emerging in the downstream direction by a coating product discharge orifice. The printing nozzles are distributed on at least two faces of a body of the applicator and the discharge orifices of these nozzles extend along at least two nonparallel planes.

An application material container has a fixed portion and a container portion. The fixed portion is configured to be fixable to a fixing member included in an application mechanism. The container portion is provided with, in upper and lower portions thereof, a hole and a hole through which an application needle passes. A side surface of the container portion has a first flange. A lower surface of the first flange is in contact with an upper surface of the fixed portion. A gap is provided between a portion lower than the first flange on the side surface of the container portion and a side surface of the fixed portion. The container portion is horizontally movable within a range of the gap.

The disclosure provides a fully new method for hot-dip metal coating treatment, as a method for treating surfaces of a metal strip by hot-dip metal coating, by which inherent issues in conventional immersion coatings and spray coatings are avoided. In the disclosed method for hot-dip metal coating treatment, a surface of a metal strip is coated by discharging a droplet of a molten metal toward the surface of the metal strip, using a nozzle system configured to discharge the droplet of the molten metal from a nozzle due to an action of the Lorentz force generated on the molten metal by sending an electric current to the molten metal in a chamber, the chamber being applied with magnetic flux in a given direction, while the electric current sent in a direction perpendicular to the given direction.

An atomizing spray nozzle device includes plural inlets that receive different phases of materials of a coating. The device also includes an atomizing zone housing portion fluidly coupled with the inlets and shaped to mix the different phases of the materials into a mixed phase slurry. The device also includes a plenum housing portion fluidly coupled with the atomizing housing portion along the center axis of the device. The plenum housing portion includes an interior plenum that is elongated along the center axis of the device. The plenum is configured to receive the mixed phase slurry from the atomizing zone. The device also includes one or more delivery nozzles fluidly coupled with the plenum. The one or more delivery nozzles provide one or more outlets from which the mixed phase slurry is delivered onto one or more surfaces of a target object as a coating on the target object.

An apparatus for dispensing a flowable material is disclosed. The apparatus comprises a rotary actuator, a reservoir, containing a hydraulic fluid, a piston, movable inside the reservoir, a linear actuator, coupled to the piston, a gear train, coupling the rotary actuator with the linear actuator, and a flowable-material dispenser, hydraulically coupled with the reservoir.

A thin-film coating applicator assembly is disclosed for coating substrates in outdoor applications. The innovative thin-film coating applicator assembly is adapted to apply performance enhancement coatings on installed photovoltaic panels and glass windows in outdoor environments. The coating applicator is adapted to move along a solar panel or glass pane while applicator mechanisms deposit a uniform layer of liquid coating solution to the substrate's surface. The applicator assembly comprises a conveyance means disposed on a frame. Further disclosed are innovative applicator heads that comprise a deformable sponge-like core surrounded by a microporous layer. The structure, when in contact with a substrate surface, deposits a uniform layer of coating solution over a large surface.

An application head of a coating product on a surface to be coated comprising at least two spray nozzles for the coating product, each spray nozzle suitable for spraying the coating product in the form of an aerosol stream, while simultaneously creating several droplets having a diameter smaller than the diameter of the outlet orifice of the spray nozzle.
