An electrostatic atomizing coating apparatus and method incorporate a rotary head having a base portion, an open end and a plurality of grooves formed radially on an inner peripheral surface of the open end, an inside diameter of the rotary head increasing from the base portion toward the open end, and a motor configured to rotate the rotary head to discharge a thread-shaped paint. A voltage is applied to the rotary head so as to form an electrostatic field between the open end of the rotary head and an earthed coating target and to electrostatically atomize the thread-shaped paint discharged from the open end. Voltage output from the generator is controlled so as to adjust an intensity of the electrostatic field and to control a particle diameter of the electrostatically atomized thread-shaped paint.

The present invention provides a laser cladding nozzle apparatus, where the laser cladding nozzle apparatus is mounted on a laser head, and the laser cladding nozzle apparatus includes a conical nozzle head, where the conical nozzle head is connected to an inner side of the laser head; the conical nozzle head includes a plurality of first powder channels, a plurality of first inlets is evenly distributed on an upper end circumference of the conical nozzle head, a plurality of first outlets is evenly distributed on a lower end circumference of the conical nozzle head, the first inlet is in communication with the first outlet through the first powder channel, and a size and a quantity of the first inlet are the same as those of the first outlet. The present invention further provides a puncturing method for a laser cladding nozzle apparatus.

The present disclosure provides a device and method for powder distribution and an additive manufacturing method, wherein different size or kind of powders could be chosen to be accommodated within a receptacle. The receptacle can uniformly mix the powder by a rotation movement, pour out the powders by the rotation movement and distribute the powders for forming a layer by a translation movement. In another embodiment, the receptacle further comprises a heating element for preheating the powders. Not only can the present disclosure uniformly mix the powders so as to reduce the thermal deformation and distribute the powder layer compactly, but also can the present disclosure distribute different kinds of powder in different layer so as to increase the diversity in additive manufacturing.

The present disclosure provides a spacer particle distribution device used for distributing spacer particles toward a surface of a glass substrate and comprising: a sealed chamber, and a base, a lift pin and multiple adsorption assemblies disposed in the sealed chamber. The adsorption assemblies are disposed correspondingly on four edge regions of the base. Each adsorption assembly is electrified independently to respectively control electrostatic adsorption force of each adsorption assembly.

A method for monitoring production of a fluid film, including: activating a dispenser to deliver appropriate material from a storage duct to a metering system for even distribution of a fluid film; allowing the fluid film to pass a sample retrieving roller; measuring the fluid film on the sample retrieving roller using a data reading device to obtain film thickness data; transmitting the data to an analyzer to examine the data against a predetermined reference value; transmitting a comparison result in real time by the analyzer to a production equipment controlling console; controlling the storage duct to dispense material through the material metering system and adjusting the film thickness; repeating the above steps to make a film thickness within the reference range; and maintaining the thickness at the narrowest tolerance deviation, and continuously delivering the film onto a substrate for production.

Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.

An applicator for dispensing multiple adhesives on a substrate is disclosed. The applicator includes a manifold that includes a first dispensing module and a second dispensing module. The first dispensing module has a first inlet and a first nozzle. The first inlet receives a first adhesive and the first nozzle applies the first adhesive to the substrate. The second dispensing module is adjacent the first dispensing module and has a second inlet and a second nozzle. The second inlet receives a second adhesive that is different from the first adhesive. The second nozzle applies the second adhesive to the substrate.

A method and a dense phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or the like installation for spraying coating powder are disclosed. In order to reduce the number of components of the dense phase powder pump that require maintenance, the dense phase powder pump is designed as a single-chamber dense phase powder pump and has only a single powder conveyor chamber for conveying coating powder.
