When purchasing wooden doors, we can observe the appearance quality of wooden doors according to the process used by wooden doors, and we can distinguish them by observing their defects.
1. Worm 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.
2. Texture: The texture of a good wood is a regular texture, such as a texture that is cluttered or has a low level of wooden door.
3. Decay: Wood tissue necrosis, mildew, discoloration, so the texture is loose and the strength is reduced.
4. 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 that the surface of the workpiece may be spotted after painting.
5. Bubbling: Bubbling is the swelling and air bubbles of the veneer after gluing. The repairing process is troublesome and greatly affects the production efficiency.
6. 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.
7. 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 due to uneven coating or low viscosity of the adhesive.
8. Crack: The grain is divided into two types: longitudinal crack and ring crack. 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.
By observing these defects and avoiding these defects, you can buy a wooden door that you are satisfied with.
