The original wooden doors, ecological doors, solid wood doors... Are these statements in the market that make you very confused? And how much do you know about the various concepts of doors? So what do you need to pay special attention to when buying a door?
Observe the quality of wooden doors
Due to the characteristics of solid wood doors and solid wood composite doors, when purchasing wooden doors, the owner can check the appearance quality of wooden doors according to the process adopted by the wooden doors, and avoid buying defective products. What are the possible defects? According to experts, the surface of solid wood doors and solid wood composite doors is made of wood or decorative veneer. The difference is that solid wood doors are painted directly on wood or not, 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) itself, and the other is the defect of paint, which mainly manifests in the following aspects.
Crack: two types of longitudinal cracks and ring cracks. The longitudinal cracks penetrate through the wood texture and gradually extend; ring cracks occur more often between wood textures and generally do not extend.
Insect eyes: The yoke left behind by insects. After the wood is dried artificially, the locusts have all died and the worms will no longer develop, but the existence of wormholes will affect the appearance.
Texture: The texture of a good wood is a regular texture, if the texture is disorganized or the level of the wooden door is low.
Decaying: The wood tissue is necrotic, moldy, and discolored, so the texture is loose and the strength is reduced.
Penetration glue: After the veneer is hot pressed and glued, the adhesive leaks from the pores of the veneer out of its outer surface to form a gel spot. Its adverse effect mainly causes the surface of the workpiece to be spotted after being painted.
Bubbling: Bubbling is the bulging and blistering of the veneer after gluing. The repair process is cumbersome, which greatly affects the production efficiency.
Cracking: refers to the veneer after the paste, the surface has a gap greater than 0.3mm, which often appears in the veneer deformation or splicing, which is a veneer sticking process most often appear a defect.
Lack of glue: refers to the phenomenon of local lack of adhesive or glue layer between the substrate and the veneer after hot pressing, which is mainly caused by uneven coating or low viscosity of the adhesive.
Solid wood doors can be different materials
In many people's minds, buying solid wood doors is certainly the same kind of material made of solid wood doors, solid wood doors such as cherry wood, but in reality, solid wood doors may not be made of the same material. According to the industry standards of wood doors prepared by the China Forest Products Industry Association, solid wood doors are wood doors made of solid wood or laminated wood of the same species or nature. Judging from the concept of solid wood doors, there is currently no strict requirement that solid wood doors must be of the same tree species, but only similar materials are required, such as similar density. If the material difference is too big, especially the difference between dry shrinkage and swellability, it is easy to warp, bulging, cracking, and the quality of wooden doors is difficult to guarantee. From the perspective of products on the market, solid wood doors may also be made of glulam, ie glued wood, which is a material obtained by integrating gluing in the direction of length, width, and thickness of a sheet material, a small square material, etc. whose fiber direction is substantially parallel. of.
Solid wood door panels may not be the same tree species, and door pockets may not be the same species. According to industry standards, the door frame is the door cover - "frame-shaped wooden components fixed to the wall door opening, supporting the movable door leaf and installing the fixed door leaf, composed of a frame, an upper frame, and a decorative board." Therefore, the door frame and the door leaf belong to The scope of the solid wood door is listed, but even the different tree species used must be similar in nature.
The original wooden door concept is not clear
Many businesses introduced their own doors as "original wood doors," claiming that their own doors were made of solid wood made of large blocks of solid wood doors that are more environmentally friendly than solid wood doors. In fact, the concept of the original wooden door is not clear.
Strictly speaking, the original wooden door is a kind of solid wood door. Logs refer to wood sections cut to a certain length according to the standard or special provisions of size, shape, and quality. "Wooden doors made of logs are known in the market as 'original wood doors', which generally refer to lengths that are not connected in length and are distinguished from finger-joint materials." But because the concept is not clear, doors that are currently glued horizontally using logs can also be Called the original wooden door.
As for eco-gates, experts pointed out that there is no such concept in academics, textbooks, and norms. People often use “ecology†to define many beautiful things. For example, healthy, beautiful, and harmonious things can be called “ecological†titles. When used on wooden doors, ecological doors are usually referred to as “environmentally friendly, healthy and safe wooden doorsâ€. It seems that as long as they comply with the relevant environmental protection and safety standards, whether it is solid wood doors, solid wood composite doors or wood composites. Doors can be called "ecological doors."
