Teach you how to distinguish the quality of wooden doors
Due to the characteristics of solid wood doors and solid wood composite doors, the owner can check the appearance quality of the wooden door according to the process used in the wooden door when purchasing the wooden door, and avoid buying defective products. So what flaws might they have? According to experts, the surfaces of solid wood doors and solid wood composite doors are made of wood or decorative veneer. The difference is that the solid wood door is painted directly on the wood or not painted, while the solid wood composite door is painted on the decorative veneer. 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 veneer (solid wood composite door surface layer) itself, and the other is the defect of paint, which is mainly manifested in the following aspects.
Cracks: There are two types of cracks: longitudinal cracks and ring cracks. The longitudinal cracks penetrate the wood texture and will gradually extend; the ring cracks mostly occur between the wood textures and generally do not extend.
Insect eyes: the dazzling eyes left after moth eaten. After the wood is artificially dried, the worms have died, and the worms will no longer develop, but the existence of worm eyes will affect the appearance.
Texture: The texture of good wood is a regular texture, such as the texture is messy or inverted, the wooden door has a lower grade.
Decay: Wood tissue is necrotic, mildewed, and discolored, resulting in loose texture and reduced strength.
Penetration: After the veneer is hot-pressed and glued, the adhesive leaks from the pores of the veneer to the outer surface to form glue spots. Its adverse effect is mainly to cause spots on the surface of the workpiece after painting.
Bubbling: Bubbling is the swelling and bubbles of the veneer after gluing. The repair process is troublesome, which greatly affects the production efficiency.
Cracking: It refers to the gap larger than 0.3mm on the surface of the veneer after pasting, which often occurs in the veneer deformation or splicing. This is also the most common defect in the veneer pasting process.
Lack of glue: refers to the partial lack of adhesive or discontinuity of the glue layer between the substrate and the veneer after hot pressing, mainly caused by uneven glue application or low adhesive viscosity.
