The Research On Surface Performance Of Furniture Fibreboard And Film Adhesion

Usually, the wood-based panel uses in the furniture manufacture having to pass through the facing. The commonly used facing way has the surface to spread the decoration, the cover and so on, has many chemistries and the physical reaction in this process occurs on its surface. Therefore, its surface quality directly will affect the face work outward appearance quality. The wood-based panel also is one kind of porous structure plate, has the small hole, it took the different material connection "the link" to characteristic and so on plate physics, chemistry, mechanics, function is playing the very important role,Only then in understood its superficial performance under the premise can a better use perhaps the pointed improvement causes it to apply afterwards in the actual production.This article take the fibreboard as the main research object, the experimental material selects the fibreboard which two companies produces to take the contrast, by eliminates the accidental factor the influence, carries on the different sand blast degree separately after two groups of test samples sand blast processing, carries on the surface roughness, the superficial wettability and the superficial absorptive determination, after but carries on to the test sample spreads the decoration, and then carries on the varnish film adhesion the determination; Analysis surface roughness, superficial wettability, superficial absorptive quality and between varnish film adhesion relations.The experiment discovered that, (1) The surface roughness to the superficial wettability, the superficial absorptive quality and the varnish film adhesion all has the certain influence. The test sample surface which processes after the sand blast free has not been able to be small, adsorption value small, the varnish film adhesion is low, this is because of the test sample surface pre- solidification level, the oxide layer existence; Increases along with the surface roughness, the superficial wettability is better, but the superficial absorptive quality and the varnish film adhesion assumes actually reduces the tendency; The 800# sandpaper processing test sample varnish film adhesion is best, the...
