Method for solidifying powder paint on lumber component surface

Abstract

The invention relates to a method for solidifying powder coatings on the surfaces of wooden components, mainly including wooden-component cleaning, wooden-component heating, spraying powder coating, baking wooden-component, etc. The invention can settle the problem of the existing methods that wooden-components decorated by the combination of paint and tianna water have the disadvantages of residue of formaldehyde, toluene and other toxic and harmful substances on the wooden-components which can not meet the green, safe and environment-friendly requirements; the wooden-components processed by the method is green, safe, environment-friendly and free of peculiar smell and the residue of formaldehyde, toluene and other toxic and harmful substances; besides, the products processed by such method is not easy to fade and scale off, and the service life is long. The production process of the invention is simple, and is applicable to processing the wooden-components made of batten, flitch, plank or composite wooden panel.

Description

technical field [0001] The invention relates to a processing method for applying a coating layer on the surface of wood parts. Background technique [0002] At present, the coatings used for decoration and beautification on the surface of wooden parts such as wooden strips, wooden squares, wooden boards or composite wooden boards used in various furniture and furniture are all formed by spraying paint. As we all know, paints generally need to be diluted with thinner before use before use. However, there are a large amount of toxic and harmful substances such as formaldehyde and toluene in the ingredients of thinner, which are harmful to the human body and the environment. When the paint is applied to the wood parts, the wood parts will remain with toxic and harmful substances such as formaldehyde and toluene. As a result, the manufactured furniture and furniture do not meet the requirements of green, safety and environmental protection due to the presence of toxic and harmf...

Problems solved by technology

There are two main reasons: First, it is generally believed that when applying the baking varnish process, the object to be baked must first be conductive and be able to attach static electricity; in this way, the powder coating can be electrostatically adsorbed on the surface of the object to be baked. Objects adsorbed with powder coating are sent to the baking equipment for baking to form a baking varnish coating; non-conductive objects cannot be attached to static electricity, and powder coatings cannot be adsorbed, and objects that cannot be attached to static electricity cannot be applied with baking varnish. Process

The second is that it is generally believed that the painted objects must be able to withstand higher temperatures. Usually only iron and steel objects can not spontaneously ignite, burn, burn, or deform in a higher temperature environment. Objects made of other materials It is not suitable for the application of baking varnish; therefore, it is generally believed that wood cannot be applied in this process condition
