Definitions
- the present invention relates to an applicator for activating a functional layer of a coating material.
- the present invention relates to a device for activating the functional layer of the coating material, a method and a use of a fluid and / or a fluid-solid mixture.
- an adhesive or an adhesive is used.
- an adhesive which is activated by an energy input and only then can produce a reliable connection between two components (coating material and workpiece).
- thermo activation of the functional layer by means of electromagnetic waves in particular in the microwave spectrum.
- electromagnetic waves in the microwave spectrum can have advantages in terms of accuracy and adaptability of the amount of energy in the functional layer.
- the thermal energy input into the functional layer of the coating material can lead to particle-containing outgassing, which can be precipitated as soiling. Even dusty ambient air or abrasion of the coating material can lead to contamination.
- the contaminants can be applied both to a region of the applicator directly on the coating material and in a cavity of the Applicator, are passed through the approximately electromagnetic waves to the coating material.
- Such contamination can lead to arcing, wherein such an arc can affect the energy input into the functional layer of the coating material and in the worst case can destroy the applicator and / or the edge band.
- the present invention provides the applicator of claim 1.
- the invention was based on the finding that the above-mentioned problems are mainly due to the fact that the known manual cleaning of the applicator requires that the applicator can not be used during cleaning.
- an applicator for activating a functional layer of a coating material comprising: a base body having at least one cavity therein, and a guide configured to guide a coating material, wherein the base body is configured to flow through the at least one cavity to allow a fluid and / or a fluid-solid mixture and / or the base body is configured to allow a filling of the at least one cavity with a fluid and / or a fluid / solid mixture.
- An applicator shown above can thus allow a flushing of the same, which prevents contamination and thus can prevent arcing.
- a cleanliness of the molten or meltable joining layer can be made possible.
- a reactive fluid and / or a reactive fluid-solid mixture for about the chemical activation of the functional layer is possible.
- a 2-component adhesive may be mentioned here, in which one component forms the functional layer of the coating material and the other component is part of the reactive fluid and / or of a reactive fluid-solid mixture.
- the adhesive component of the coating material can be chemically activated by means of the fluid.
- markings for example for marking missing parts.
- introduction of a fluid or fluid-solid mixture can be provided with coloring properties.
- the activation of the functional layer of the coating material requires a protective atmosphere, then this can also be provided by the fluid or fluid-solid mixture.
- a targeted regulation or control of the process of energy input into the functional layer during the activation of the functional layer can be made possible by the flushing.
- the energy input into the functional layer is made possible by means of electromagnetic waves, such as microwaves, for example, then the use of a fluid or solid mixture having dielectric properties can change the propagation of the electromagnetic waves such that a maximum of the wave propagates at a velocity in the propagation velocity electromagnetic wave is located.
- the efficiency of energy transfer into the functional layers can be maximized.
- a pre- or post-treatment of the coating material is conceivable, for example by means of a chemical treatment thereof.
- the applicator preferably additionally has at least one preferably controllable or controllable fluid or fluid solids feed for supplying the fluid and / or a fluid-solid mixture into the at least one cavity and / or at least one preferably controllable or controllable fluid or fluid solids removal for discharging the fluid and / or the fluid-solid mixture from the at least one cavity.
- Fluid or fluid solids feeds and / or fluid or fluid solids discharges may allow for well-controlled fluid or fluid-solid mixture rinse. This is possible both by means of manual adjustment of the rate of delivery or removal, as well as by a control thereof. This can be done, for example, to regulate the preheating / cooling shown in the previous, so to ensure optimal energy input into the functional layer.
- the applicator is an applicator that is configured to thermally activate a functional layer of a coating material by means of electromagnetic waves, even more preferably microwaves.
- Electromagnetic waves in particular microwaves, have proved to be particularly advantageous for heating functional layers of coating material.
- the applicator may be even more preferably configured to electromagnetic waves within the cavity of the To guide main body to a functional layer of a coating material.
- a shield for the electromagnetic waves can be achieved, further, the applicator is thus independent of spatial conditions at the installation.
- the applicator is configured such that the fluid and / or the fluid-solid mixture flows through a region of the applicator in which the guide is provided.
- Contaminations can occur in particular on the coating material and thus on the guide, for example due to abrasion or outgassing during heating.
- the flow can thus dissipate such contamination in a particularly efficient manner and in particular keep the leadership of the applicator clean.
- the present invention further provides a device for thermally activating a coating material, comprising: a generator for generating electromagnetic waves, in particular microwaves, and an applicator, as described above, which is designed to apply the electromagnetic waves generated in the generator to the coating material ,
- the device is thus able to generate electromagnetic waves, in particular microwaves, and subsequently transfer these to a coating material while avoiding deposits of contamination.
- the present invention provides a method of thermally activating a functional layer of a coating material, which method comprises Thermal activation of a functional layer of a coating material preferably by means of electromagnetic waves, in particular microwaves, and flowing through a cavity of the applicator with at least one fluid and / or a fluid-solid mixture, wherein the last two process steps preferably at least partially run simultaneously.
- this method is performed using an applicator as set forth above and / or using a device as shown above.
- the present invention discloses the use of a fluid and / or a fluid-solid mixture for flowing through an applicator for thermally activating a functional layer of a coating material.
- the use of the fluid and / or the fluid-solid mixture has as a technical effect to enable a simple and quick cleaning of the applicator.
- Fig. 1 shows a sectional view of a preferred embodiment of an applicator according to the invention.
