Abstract
The invention relates to a method for coating particles of a plastic, metal and/or ceramic powder material for producing an adhesive-containing coating material, in particular for producing appropriate particles by compressing a 3D binder. Said coating is applied to fluidized particles in a gaseous phase by means of a coating solution, at least the particles and/or coated particles being exposed to ionized particles. A method for producing bodies or sintered bodies from organic liquid binders by compressing the 3D binder and the use thereof are also disclosed.
Claims15
A method for coating a plastic, metal and/or ceramic powder material with a coating containing a binder liquid activatable or laser light activatable organic or organo-meteallic adhesive, the method comprising:
- providing particles of the powder material to be coated in a fluidized form in a gas phase;
- and
- depositing the organic or organo-meteallic adhesive from a solution onto the particles of the powder material to form coated particles
- wherein the particles, the coated particles or the gas space in which the particles are present in fluidized form are exposed to sufficient ionized particles to reduce the electrostatic charging of the powder material and/or the coated powder material.
