  • Publication number: 20160185063
    Abstract: In a method of compaction of a powder (P) by means of nip rollers the powder (P) is transported at a supply speed to the nip rollers and friction between at least one of the nip rollers and the powder (P) at said nip roller is determined. Depending on the friction the rotational speed of at least one of the nip rollers is adjusted. The supply speed of the powder (P) to the nip rollers as well as the distance between the nip rollers are maintained substantially constant.

  • Patent number: 8377346
    Abstract: A process for the manufacture of a powder coating comprising the steps of: Preparing a powder coating premix comprising a resin and optionally a crosslinker therefor; Feeding the premix through a melt extruder; Cooling the extruded material; and Comminuting it to fine particles, wherein said process is characterized in that between 1 and 25 wt. % (based on the weight of said premix) of a process liquid is added to the melt extruder, wherein said process liquid is immiscible with at least said resin of the powder coating premix and wherein said process liquid evaporates when the premix leaves the extruder.

  • Publication number: 20090017209
    Abstract: The present invention pertains to a process for preparing a powder coating composition, the process comprising the steps of: a. providing a set of base compositions, each base composition comprising a liquid carrier and one or more constituents responsible for an intended property of the coating product, at least one base composition A being an aqueous dispersion or emulsion of a film-forming material, b. selecting base compositions to be used to obtain the intended end product property, said base compositions comprising at least one base composition A as specified; c. mixing the selected base compositions in a ratio suitable to obtain the intended end product property; d. drying, preferably spray-drying, the mixture of base compositions or otherwise removing the liquid carrier(s), and e. simultaneously or subsequently, combining the particles of the base compositions into larger particles. Preferably, the particles of film-forming material in base composition A have a d(v,50)<5 ?m.

  • Publication number: 20080261142
    Abstract: The present invention pertains to a process for the preparation of a toner powder, in which particles of one or more toner base compositions are combined into larger particles. The toner base compositions may be in the form of dry powders, e.g., manufactured by jet milling or by freeze drying powder dispersions. In that case, the combination of the toner base compositions into larger particles may be done by, e.g., mechanofusion. The toner base composition may also be in the form of an aqueous emulsion or dispersion. In that case, the combination of the base compositions into larger particles can be effected by spray-drying the emulsion or dispersion. In a preferred embodiment, the toner base composition in aqueous form is prepared via phase inversion emulsification, which preferably is carried out in an extruder.

  • Patent number: 5856378
    Abstract: A powder coating composition, suitable for providing a coating having certain appearance or performance attributes, which includes composite particles that are agglomerates of individual particulate components fused or bonded together into composite particles such that the composite particles are air-fluidizable and can be applied to a substrate by electrostatic spray without causing the individual particles in the composite particles to break down under the mechanical and/or electrostatic forces associated with their application to a substrate.
