Editor's note: Original wooden doors, ecological doors, solid wood doors... Are these statements in the market very confusing? How much do you know about the various concepts of the door? So what do you need to pay special attention to when buying a door? Observe the quality of wooden door identification Due to the characteristics of the solid wood door and the solid wood composite door, the owner can view the appearance quality of the wooden door according to the process adopted by the wooden door when purchasing the wooden door, and avoid buying defective products. So what defects might they have? According to experts, the surface of solid wood doors and solid wood composite doors are wood or decorative veneers. The difference is that solid wood doors are painted directly on the wood or not painted, while solid wood composite doors are painted on decorative veneers. According to the manufacturing process of these two types of doors, their appearance quality defects include two parts: one is the defect of wood or thin wood (solid wood composite facade layer) itself, and the other is the defect of paint, which is mainly manifested in the following aspects. Crack: There are two types of longitudinal cracks and ring cracks. The longitudinal crack penetrates the wood texture and gradually extends; the ring crack is mostly generated between the wood texture and generally does not extend. Insect eye: the eye that remains after the insect. After the wood is artificially dried, the mites have died, and the worms will not develop any more, but the presence of the worms will affect the appearance. Texture: The texture of a good wood is a regular texture, such as a messy texture or a low level of wooden door with inverted flow. Decay: wood tissue necrosis, mildew, discoloration, so the texture is loose and the strength is reduced. Penetration: After the veneer is vulcanized, the adhesive leaks out of the outer surface of the veneer to form a rubber spot. The adverse effect is mainly caused by the surface of the workpiece after the paint may be spotted. Bubbling: Bubbling is the swelling and air bubbles of the veneer after gluing. The repairing process is troublesome and greatly affects the production efficiency. Cracking: After the veneer is pasted, the surface produces a gap larger than 0.3mm, which often occurs in the large deformation or splicing of the veneer. This is also the most common defect in the veneer bonding process. Lack of glue: refers to the phenomenon of partial lack of adhesive or discontinuity of adhesive layer between the substrate and the veneer after hot pressing, mainly caused by uneven coating or low viscosity of the adhesive. Solid wood doors are not the same material In many people's impressions, the solid wood door must be made of solid wood doors made of large pieces of wood of the same kind, such as solid wood doors of cherry wood, but in fact, solid wood doors may not be made of the same material. According to the wooden door industry standard compiled by the China National Forest Products Industry Association, the solid wood door refers to the wooden door made of solid wood or laminated timber with the same tree species or similar properties. According to Wu Shengfu, director of the marketing department of the China National Forest Products Industry Association, from the concept of solid wood doors, there is no strict requirement that the solid wood doors must be the same tree species, but the materials are similar, such as similar density. If the material difference is too large, especially the difference between dry shrinkage and swelling is too large, it is easy to lift, bulge, crack, and the quality of the wooden door is difficult to guarantee. From the products on the market, solid wood doors may also be made of glulam (that is, glulam, which is a material in which the fibers are substantially parallel in the direction of the length, width and thickness). of. The solid wood door panels may not be the same tree species, and the door pockets may not be the same tree species. According to industry standards, the door frame is the door cover. “The frame-shaped wooden members that are fixed to the wall door opening and support the movable door leaf and the fixed door leaf are composed of the frame, the upper frame and the decorative plate.†Therefore, the door frame and the door leaf belong to The range of solid wood doors is specified, but even the different species used must be similar in nature.
