Method for forming adhesive layer
In a method for forming an adhesive layer on the surface of a workpiece before the formation of a coating film containing a powder on the workpiece, the present invention provides a method for forming the adhesive layer having a desired thickness. This object is achieved by the following method: An adhesive layer formation medium m 1 coated with an adhesive material is made to collide with a workpiece W so that the adhesive material is transferred from the adhesive layer formation medium m 1 to the workpiece W and forms an adhesive layer on the workpiece. An adhesive layer having a desired thickness can be formed on the workpiece by regulating the thickness of the adhesive material applied to the surface of the adhesive layer formation medium (i.e. the amount of the adhesive material held by a single adhesive layer formation medium). This enables the thickness of the powder coating as the final product to be controlled as desired.
1. A method for forming an adhesive layer comprising:
putting adhesive layer formation media coated with adhesive materials and at least one workpiece into a container;
vibrating or stirring in the container the adhesive layer formation media and the at least one workpiece so that the adhesive layer formation media and the at least one workpiece collide with each other, thereby forming an adhesive layer on the surface of the workpiece.
2. The method for forming an adhesive layer according to claim 1 , further comprising forming the adhesive layer on a surface of the at least one workpiece having little or no adhesive material applied to it.
3. The method for forming an adhesive layer according to claim 1 , further comprising forming an adhesive layer on the adhesive layer formation media, the thickness of the adhesive layer being maintained within a specific range so that the adhesive layer to be formed on the at least one workpiece has a uniform thickness.
4. The method for forming an adhesive layer according to claim 1 , wherein the adhesive material contains a liquid material.
5. The method for forming an adhesive layer according to claim 4 , wherein the adhesive material contains a liquid resin.
6. The method for forming an adhesive layer according to claim 5 , wherein the liquid resin contains a curing agent.
7. The method for forming an adhesive layer according to claim 1 , wherein the adhesive material contains spacer particles.
8. The method for forming an adhesive layer according to claim 1 , wherein the adhesive material consists of a substantially non-volatile material.
9. The method of claim 1 further comprising:
putting the at least one workpiece with the adhesive layer, particles of powder, and powder-coating media into a container; and
vibrating the at least one workpiece with the adhesive layer, particles of powder, and powder-coating media in the container.
10. The powder-coating method according to claim 9 , wherein the adhesive material contains spacer particles, which consist of particles of the powder.
