摘要： Apparatus and methods for detecting flow of powder coating material in an electrically nonconductive powder hose include providing an electrically conductive material that extends along at least a portion of the length of the hose to collect tribo-charge transfer that is produced by frictional contact between the powder coating material and an interior surface of the hose. The collected tribo-charge transfer is used to produce an electrical current in the electrically conductive material. A circuit detects the current in the electrically conductive material and produces an output that indicates whether powder coating material is flowing through the hose.

摘要： An apparatus for applying electrostatic powders on manufactured articles, comprising at least one dispensing device adapted to dispense gas solid particles mixture having an electrostatic charge, and connected to at least one duct arranged proximate to the surface to be treated and defining a channel for conveying the mixture. The duct has laterally, along its longitudinal extension, at least one passage opening directed toward the surface to be treated. A partition is arranged with at least one of its portions substantially at the passage opening and is permeable to the powder particles.

摘要： Abstract of DisclosureA method and device is provided for detecting a flow of particles, particularly paint particles, in a powder transportation line connected to a powder spray gun. The powder transportation line of the device includes a portion having an interior face provided with an electrostatically friction-charging material. The portion of the transportation line may be located upstream or downstream of the pump or within the pump itself. The transportation line portion is in electrical communication with a unit for sensing electrical signals. When the powder particles flow through the transportation line portion, an electrical charge is generated in the portion as a result of the friction between the particles and the friction-charging material. This electrical charge is detected by the sensing unit .

摘要： The present invention is directed to a process for the application of fluoropolymer to a preselected area of a threaded fastener, and particularly to substantially all of the threads of the fastener. The fluoropolymer is supplied to a spray nozzle in powder form and is subjected to a triboelectrostatic charging process so that individual particles discharged from the spray nozzle are electrically charged to between about 1×10−7 to about 3×10−3 coulombs per kilogram. In the preferred form of the invention, the fluoropolymer powder is triboelectrically charged, entrained in an air stream discharged from the nozzle and directed onto the preselected area of the fastener. In this manner a generally uniform powder coating is deposited onto the preselected area of the fastener while the fastener is maintained at room temperature. Thereafter, the fastener is heated to a temperature above the melting point of the fluoropolymer to thereby coalesce the deposited powder into a continuous film coating which adheres, upon cooling, to the preselected area of the fastener. In accordance with a preferred embodiment, the fastener is heated in a manner which raises the temperature of only the preselected area of the fastener to the fluoropolymer melting point. This preferred heating technique minimizes the retention of fluoropolymer inadvertently deposited on areas of the fastener other than the preselected area, and allows this undesired fluoropolymer to be easily removed, even after heating.

摘要翻译： 本发明涉及将氟聚合物应用于螺纹紧固件的预选区域，特别是基本上所有紧固件的螺纹的方法。 氟聚合物以粉末形式供应到喷嘴，并进行摩擦静电充电过程，使得从喷嘴排出的单个颗粒充电至约1×10 -7至约3×10 -3库仑/千克。 在本发明的优选形式中，含氟聚合物粉末被摩擦带电，夹带在从喷嘴排出的空气流中并引导到紧固件的预选区域。 以这种方式，当紧固件保持在室温下时，将大致均匀的粉末涂层沉积到紧固件的预选区域上。 此后，将紧固件加热到高于含氟聚合物的熔点的温度，从而将沉积的粉末聚结成连续的膜涂层，其在冷却时粘附到紧固件的预选区域。 根据优选实施例，紧固件以将仅紧固件的预选区域的温度升高到含氟聚合物熔点的方式被加热。 这种优选的加热技术使得聚合物无意地沉积在除了预选区域之外的紧固件的区域上的保留最小化，并且即使在加热之后也允许这种不需要的含氟聚合物被容易地去除。
