First, what is the finger board?
Fingerboard, also known as Glulam, is made by splicing multiple pieces of wood, and the upper and lower parts are no longer glued and clamped. Because the vertical boards use a saw-tooth-like interface, similar to the two-handed fingers, they are called finger-joints. Finger joints do not need to paste the board on the board, the amount of glue is greatly reduced, the sheet is very environmentally friendly, finger board can basically reach the E0 level, is why we like this kind of sheet material is one of the reasons. Fingerboards are often used in furniture, cabinets, wardrobes and other excellent materials.
Fingerboard size specifications:
The specifications of the artificial plate are generally: 2440mm (length) x 1220mm (width) x thickness. Fingerboard thickness is generally 9mm, 12mm, 14mm, 15mm, 16mm, 18mm, etc. The thickest is 25mm.
Second, finger board purchase:
1. Fingerboard is made by splicing solid wood short strips. The bigger the strips, the better.
2. The biggest defect of the fingerboard is that it is easily deformed, resulting in deformation due to changes in the internal stress during the dry shrinkage and swelling. Therefore, it is very important for the finger-plate to have a moisture content standard, and the palm of the hand feels cold and chilly.
3, Fingerboard is also divided into two types of knots and no festivals, there is a section of the fingerboard eye blink, no finger joint plate does not exist blink, looks more beautiful.
4. In general, the bigger the annual rings of the slat core material of the fingerboard, the longer the tree age and the better the material. Thousands of years, the fingerboard of the boat is processed into large-diameter logs, and the core board has good hardness and is not easily deformed.
5. The slats of the fingerboard are linked together by an adhesive. The glue strength of the plate has an important influence on the quality of the fingerboard. The splicing gap between the slats is small and there is no shortage of glue and degumming.
6. The fingerboard is divided into a bright tooth and a dark tooth, and the dark tooth is the best, because the bright tooth is more prone to unevenness after being painted. Of course, dark teeth are more difficult to process.
Third, finger board type:
1, Fingerboard according to whether the surface of the tree section, divided into knot and no knot two kinds:
1 knotless fingerboard: after careful selection of material selection, picking out the no-wood section of the wood to make a fingerboard looks beautiful.
2 finger jointed board: stitching short wood will have a tree knot, the appearance is worse. However, in some furniture, made of the same size of wood, the uniform scar itself is also a kind of decoration.
2. Fingerboard According to the type of spliced ​​sheet wood, the following are common: fir finger board, rubber wood finger board, oak finger board, pine finger board, Pinus sylvestris finger board, citron finger Boards, paulownia fingerboards, beech fingerboards, etc.
3. According to the carrying condition, the fingerboard can be divided into fingerboards for structures and fingerboards for non-structures.
1 Fingerboards for structural use are load-bearing components that require fingerboards with sufficient strength and rigidity. It is mainly used for wood structure beams in gymnasiums, concert halls, factories, warehouses and other buildings. Among them, three-joint arched beams are most commonly used. These are non-structural fingerboards that cannot be realized in previous wooden structures. That is, the fingerboards that are commonly used for decoration. Mainly used as furniture and interior decoration materials: such as interior doors, windows, cabinets beams, columns, decorative columns, stair railings, chair brackets, armrests, backrests, sofas, coffee table and other curved parts, and decorative strips and other materials.
