Abstract:
The present invention relates to an apparatus and a method for dyeing glass and, more particularly, an apparatus and a method, by which both surfaces of hot sheet-like glass may be dyed simultaneously and/or the surface containing tin residues of the sheet glass may be dyed to have a different colour than the surface without tin residues. The apparatus of the invention may be used for dyeing both sheet glass and utility glass, such as glass beakers.
Abstract:
The invention relates to a method and a device for applying a plastic layer, containing a filler, to a surface. According to the inventive method, a mixture containing a binding agent or a binding agent mixture and a filler is sprayed onto the surface. A free jet (3) of the binding agent or binding agent mixture is produced for the spray application, and the filler is then added to the free jet (3) of the not yet polymerised binding agent or binding agent mixture in a dosed manner. The inventive method is especially suitable for the spray application of heavy layers such as those applied in conventional mass-spring systems.
Abstract:
The aim of the invention is to provide a method for producing insulations of electric conductors by means of powder coating which is characterized by an improved aging behavior compared to glass-mica or cast resin insulations and to also provide a powder appropriate for use in the inventive method. To this end, the powder is applied repeatedly up to a layer thickness of
Abstract:
A method and apparatus for coating the outer surface of a workpiece (W) comprises disposing a workpiece (W) in a fixed position along an axis and rotating a thermal spray gun (7) around the axis on a support (5) with a thermal spray (S) thereof directed towards the axis. The powder, fuel and oxygen are rotatably coupled to the gun (7) and the thermal spray gun (7) and the support (5) are moved along the axis while rotating.
Abstract:
The disclosure relates to a method of coating a high-strength aluminium object with polymer and surface-treating it, for improved corrosion resistance. A polymer composition is coated onto the surface (c) of the aluminium object and is sintered or melted fast, at the same time as solution treatment (f) for precipitation hardening takes place. The polymer composition substantially comprises a fluorine-containing polymer, preferably PTFE. According to one preferred embodiment of the method according to the present invention, the polymer coating is sintered or melted fast on the aluminium surface during approx. 15 minutes at approx. 420 DEG C. After solution treatment and simultaneous surface treatment at elevated temperature, the aluminium object is rapidly cooled to room temperature (g) and precipitation hardened thereafter by means of artificial ageing (j) preferably at approx. 120-150 DEG C during approx. 24 hours.
Abstract:
The method for spraying thermoplastic powders provides to feed a flow of compressed air and/or nitrogen and a liquefied petroleum gas through respective separated discharge chambers (9, 12), shaped inside a mixing device (1) of a spray gun (100), the separated discharge chambers (9, 12) being in communication with a mixing chamber (15). Then a flame is ignited at the mixing chamber, through a flame ignition device (30) connected with the gun (100), said device comprising a spark ignition device (31, 310), and a conductor element (32) associated with the mixing device (1) and connected with the spark ignition device (31, 310). The thermoplastic powders are mixed with a transport inert gas, and fed through a further discharge chamber (7) communicating with the mixing chamber (15). Then the spray gun is operated to spray the thermoplastic powders through the flame onto the surface of the article to be coated, to cause the melting of the same powders.

Ce procédé comprend les étapes suivantes: fourniture d'un dispositif de greffage (20) comprenant une torche (26) produisant une flamme (28) dans un volume d'air ambiant, et un support (33) de refroidissement disposé en regard de la flamme (28); défilement continu du matériau allongé (14) à travers la flamme (28) entre la torche (26) et le support de refroidissement (33); greffage continu de nanostructures de carbone (16) sur le matériau allongé (14) lors de son défilement à travers la flamme (28).
Abstract:
A surface treatment device that comprises a burner and an impaction chamber that encloses the flame of the burner. Temperatures in the impaction chamber are controlled such that the temperature of the flow of particles at the elongated outlet opening is lower than 70 % of a bulk melting point of the particles. The impaction chamber is further dimensioned to reduce the cross-sectional dimension of the flow towards an elongated outlet opening of the impaction chamber. Probability of the desired surface treatment processes to take place increases and better spatial distribution of particles in the treated areas is achieved.
