Abstract:
Glassware coating process and apparatus including an oven and fluidized bed arrangement that preheats, dip coats and cures a thermoplastic shatterproof polymer on ware in a continuous fashion. The apparatus, among other things, includes a gripper device adapted to seize a plurality of ware simultaneously and transfer same through the coating stage. Similarly, there are disclosed techniques and apparatus for pre-heating, curing, applying variable coating thicknesses and transferring and lubricating coated ware.
Abstract:
The disclosure relates to a method of priming paper web for its firm and even bond with subsequently applied molten polyolefin as a coating. The method provides for continuously feeding a paper web at relatively high speed to and past a station at which there is directed against the face to-be-coated of the passing web stiff flame which is fed by a combustible mixture of gas and air at a ratio to obtain substantially complete combustion of the mixture at the flame tip, thereby to cause a decrease in the polarity of the cellulose structure of the web face for enhanced adhesion of the subsequently applied molten polyolefin to this web face.
Abstract:
A method for coating a surface of an electrically non-conductive substrate with powder coatings, the method comprising the following steps: providing a substrate to be coated, pre-heating the substrate to be coated to a temperature of 40 to 140° C. in order to decrease the surface resistance of the substrate to less than 1012 ohms, preferably to within the range of 1010 to less than 1012 ohms, electrostatically coating the surface with powder coating in a single layer, which powder coating comprises a reactive system which, in particular, cures into a thermoset, curing the powder coating layer at a temperature of 170° C. or less.
Abstract:
A method of applying a wear-resistant coating comprises mixing about 75% to about 85% by weight chromium carbide and about 15% to about 25% by weight nickel chromium to form a chromium carbide-nickel chromium mixture, and simultaneously heating the chromium carbide-nickel chromium mixture to about 1371 degrees Celsius to about 2204 degrees Celsius and applying the chromium carbide-nickel chromium mixture at a velocity in a range of about 305 meters feet per second to about 915 meters per second by high velocity oxygen fuel (HVOF) spraying.
Abstract:
The invention relates to a process for the production of strongly adherent coatings on an inorganic or organic substrate, wherein in a first step a) a low-temperature plasma, a corona discharge or a flame is caused to act on the inorganic or organic substrate, in a second step b) one or more defined photoinitiators or mixtures of defined photoinitiators with monomers, containing at least one ethylenically unsaturated group, or solutions, suspensions or emulsions of the afore-mentioned substances, are applied, preferably at normal pressure, to the inorganic or organic substrate, in a third step c) using suitable methods those afore-mentioned substances are dried and/or irradiated with electromagnetic waves and, optionally, in a fourth step d) on the substrate so pretreated is applied a further coating.
Abstract:
A method of electrostatic spraying of a polymer surface involves oxidation and treating the oxidised surface with a polyamine and an electroconductivity modifying agent which contains a mono-carboxylic acid of from one to 12 carbon atoms.
Abstract:
A printhead for an inkjet printer comprises a wafer assembly defining a plurality of spaced apart groups of ink supply channels and a plurality of groups of ink ejection nozzle arrangements. Each ink ejection nozzle arrangement comprises a nozzle chamber structure mounted to the wafer assembly. Each ink ejection nozzle arrangement further comprises an anchor extending from the wafer assembly in a location external to the nozzle chamber; and an elongate thermal actuator mechanism extending from the anchor and into the nozzle chamber. The thermal actuator mechanism comprises an elongate arm which terminates in a free end within the nozzle chamber, and a pair of layers of conductive material located on either side of the elongate arm. One of the layers is connected to a current supply for causing a differential thermal expansion in the elongate thermal actuator mechanism. A pit is defined adjacent each nozzle chamber structure for catching ink. The ink ejection nozzle arrangements of each group are arranged in a pair of rows, with the elongate thermal actuator mechanism of ink ejection nozzle arrangements of a first row extending away from those of ink ejection nozzle arrangements of a second row.
Abstract:
A method for forming an inorganic or hybrid organic/inorganic layer on a substrate, which method comprises applying a metal alkoxide to form a layer atop the substrate and exposing the metal alkoxide layer to heat from a catalytic combustion heater in the presence of water to cure the layer is provided.
