Artificial boxwood wood substrate moisture content
The artificial boxwood with uneven water content is prone to deformation, so the pressed plate should be placed for a period of time to make the internal moisture content tend to be uniform. The artificial boxwood wood for decoration shall be adjusted to a certain range according to the decoration materials and technical requirements before decoration, generally 8% to 10%. Low moisture content The adhesive or coating has poor wettability on the surface of the substrate and does not have the proper bonding strength and adhesion. Excessive moisture content not only does not get the proper bonding strength, but also easily causes defects in the decorative surface.
The surface layer of the artificial boxwood maintains the wood texture and structural features of the wood string cut surface, ie has void faces, ducts, knots and surface irregularities. Due to the rotary cutting process, there are cracks on the surface. The particle board differs greatly depending on the shape and composition of the shavings. Since the shavings are intertwined, a lot of grooves are formed, which makes the surface uneven, especially for single-layer structural plates, and the surface layer is extremely rough. The surface of the three-layer particleboard is flatter due to the use of finer materials. There are no defects such as ducts and knots on the surface of the hard fiberboard, and the surface flatness is high, but often paraffin or the like floats on the surface of the fiberboard to reduce the bonding performance. There are also wire mesh marks on the back of the artificial boxwood board, which is relatively loose and easily causes deformation during use. The medium density fiberboard has high fiber separation, small unit, smooth and delicate surface and uniform internal texture, which is a good quality furniture and decoration material. Blockboard and finger jointed laminated timber, due to its structure similar to natural wood, has good dimensional stability and moisture resistance, and has been widely used in furniture and decoration, especially blockboard, in artificial boxwood It has become one of the high-yielding plate types.
