In home decoration, the most used material is undoubtedly the plate, which is not only practical but also variable. So, as a member of sheet metal, how much do you know about the terminology of sheet metal? Let us learn what these sheet terms mean. 1. Air-dry density The relationship between volume and weight after the wood is completely dry varies with the tree species, and generally refers to the wood moisture content between 10% and 14%. The median value is 12% of the wood moisture content as the standard for wood drying, which is " The meaning of "dry". The so-called air-dry density refers to the weight of 1 cubic centimeter of wood when the wood moisture content is 12%. If this value is 1, it has the same specific gravity as water, and the wood will basically sink in water; if this value is less than 1, the wood will not sink; if this value is greater than 1, the wood will sink quickly. The concept of "submerged materials" usually refers to the air-dry density of wood greater than or equal to 1. Air-dry density is not only a basic indicator to measure the specific gravity of wood, but also an important indicator to measure the material. In most cases, the air-dry density of wood (core material) is close to 1 or greater than 1, which is high-quality dark precious wood. 2. Wood Woodiness refers to the deformation rate of wood during natural drying or after it is made into furniture, so the smaller the woodiness, the better the material. But the law of wood is: the harder the material, the better, but often the harder the material, the greater the performance. For example, the high-grade ebony in Africa has a very good material, and the hardness of the wood is almost the most of all hardwoods. However, as the so-called "it is easy to break", the woodiness of this ebony is particularly great. It needs to be manually shaped. Almost a whole year is not enough; if you let it dry naturally, it will be difficult to dry in ten years. So we must balance the relationship between the two. 3. Material The pros and cons of wood materials include multiple factors. The methods and angles of observation are different, and the aspects of inspection are different. In general, the quality of the materials should be investigated from the oiliness of the wood (the higher the better), the fineness of the wood structure (the thinner the better), the air-dry density of the wood (the bigger the better), the size of the wood and the color of the wood (Wood), board surface color (the brighter the better), wood diameter (wood diameter or wood board width, the bigger the better) and other considerations. 4. Logs That is, pure solid wood, refers to natural solid wood materials that have not been reprocessed, and wood that does not use any artificial board. Log custom home products All wood products parts must be processed with sawn timber [finished timber or semi-finished timber (integrated timber, etc.) made from logs). The wood grain and wood ray of pure solid wood (if it is usually displayed as a "needle" is clearly visible, there should be more or less natural defects (wood knots, wood spots, black lines, etc.) to release a piece of solid wood, whether it is a wooden slab It is a wooden strip, and the grain of the two interfaces should clearly show the natural connection between the longitudinal section and the cross section. 5. Solid wood The wood used for custom home made from the assembly of sawn timber and plywood [pillar profiles made of wood as raw material by gluing and pressing and various boards (multilayer board, density board, gray core board, particle board, etc.). 6. Artificial board Using wood or other non-wood plants as raw materials, it is processed into veneer, shavings or fibers and other component materials of different shapes, and the board is recombined by applying (or not adding) adhesives and other additives. 7. Veneer Wood grain and wood rays are clear. There should also be natural flaws. Because the veneer has a certain thickness (about 0.5 mm) when making furniture, when encountering two adjacent intersections, they usually do not turn, but stick each one, so the wood grain of the two intersections should not usually be connected. The veneer furniture is solid wood furniture from the appearance. The natural texture, feel and color of the wood are exactly the same as the solid wood furniture, but it is actually a combination of solid wood and artificial board furniture, that is, side panels, top, bottom, shelves and other components Particleboard or MDF fiberboard with veneer veneer is used, and doors and drawers are made of solid wood. 8. Stickers Wood grain and wood rays are clearly visible. Even imported high-quality paper can even imitate wood flaws, but it is still different from natural wood veneer and looks fake. Sticker furniture is prone to flaws in the corners. In addition, due to the small thickness (0.08 mm) of the wood grain paper, the junction between the two planes will be wrapped directly, causing the wood grains of the two interfaces to be connected, which are usually longitudinal sections). 9. String cut String cutting, a method of cutting wood to observe the wood, is generally sawed at a 45-degree vertical angle with respect to the trunk, and then planed the cut surface. The chord cut surface is the most convenient to observe the effect of wood grain and material structure. 10. Cross section Cross-cutting is also a method of cutting wood for observing the wood. It is sawn at 90 degrees relative to the vertical angle of the tree trunk, and then the cut surface is planed. The cross section is convenient for observing the growth rings of wood, the compactness of the material structure, crystal, oiliness, etc. 11. Longitudinal section Longitudinal cutting, also known as radial cutting, is one of the three main methods of cutting wood for observing wood, sawing it parallel to the tree trunk, and then planing the cut surface. Longitudinal cutting of hardwood must be performed on the core material. The longitudinal section is convenient for observing the wood grain, color, and fineness of the material. A plate brand can stand up in the market in the industry, and can pay attention to the improvement of the brand image, then the product quality is definitely understandable. Consumers are willing to pay for the brand, and naturally the brand has its core competitiveness to impress consumers.
