Do you know how little you know about the wooden door?
Observe the quality of wooden doors to identify
Due to the characteristics of solid wood doors and solid wood composite doors, the owners can view the appearance quality of the doors according to the process used in the wooden doors to avoid buying defective products. So what defects do they exist? Experts, solid wood doors and solid wood composite doors for the surface of wood or decorative veneer, the difference is that the solid wood doors are directly brushing the wood above the paint or not paint, and solid wood composite doors are painted on the decorative veneer. According to these two types of door manufacturing process, their appearance quality defects include two parts: one for the wood or veneer (solid wood composite facade) itself defects, one for the paint defects, mainly in the following areas.
crack:
Pattern of longitudinal and split split two. Longitudinal flow to penetrate the wood texture, and will gradually extend; ring cracks are mostly produced between the wood texture, generally does not extend.
Insect eyes
That is, after the moths left the garish. Wood by artificial drying, the borers have died, no longer have the development of insects, but the presence of insects will affect the appearance.
Texture:
Good wood texture is a regular texture, such as texture is chaotic or down the stream of wood doors lower level.
decay:
Wood tissue necrosis, mildew, discoloration, and thus loose texture, reduced strength.
Glue:
Refers to the hot plate gluing, the adhesive from the pores of the veneer leakage of its outer surface to form a spot, its adverse effects are mainly the surface of the workpiece after the paint may produce spots.
Bubble:
Bubble is veneer in the glue after the emergence of bulging and bubbles, and its repair process more trouble, greatly affected the production efficiency.
Cracking: refers to the board after the paste, the surface produces more than 0.3mm gap, which often appears in the veneer deformation or splicing, which is veneer paste the most common defects in the process.
Lack of glue:
Refers to the hot pressing, the substrate and the board between the local lack of adhesive or adhesive layer of the phenomenon of discontinuity, mainly uneven adhesive or adhesive viscosity caused by lower reasons.
Solid wood doors may be of the same material
In the impression of many people, buy solid wood doors must be the same kind of material made of wood solid wood doors, such as cherry wood solid wood doors, etc., but in fact, solid wood doors may not be made of the same material. According to the China Wood Products Industry Association, the wooden door industry standard, solid wood door refers to the door, the door frame by the same tree species or similar nature of solid wood or laminated wood made of wood doors. According to the China Forest Products Industry Association Marketing Director Wu Shengfu introduction, from the concept of solid wood door, there is no strict requirements of solid wood doors must be the same tree species, but require similar material can be similar, such as density similar. If the material difference is too large, especially the dry shrinkage expansion difference is too large, easy to Qiao, drum package, cracking, wood quality is difficult to guarantee. From the market products, solid wood doors may also be the use of Glulam (that is, glued wood, the Department of the fiber is basically parallel to the plate, small square, etc. in the length, width and thickness of the direction of the integrated glue from the material) of.
Solid wood door panels can not be the same species, door sets can not be the same species. According to industry standards, the door frame is the door - "fixed in the wall door openings, supporting the activities of the door and the installation of fixed doors of the box-shaped wooden components, by the border, the box and decorative panels." Therefore, the door frame and doors are Solid wood doors of the provisions of the column, but even if the use of different species, the nature must be similar.
