Refers to finger joint plywood made of solid wood short strip processing, it has not changed the basic characteristics of real wood, sheet is man-made plank in the environmental protection is very good, also is one of the main material of solid wood furniture, for example, solid wood cabinet, drawer, cabinet put oneself in another’s position on the market and other parts made, mostly refers to meet its quality fit and unfit quality will affect the service life of solid wood cabinets. So, how to choose a finger joint plywood? What is the thickness and specification of the finger joint plywood?
What is the finger joint plywood?
Finger joint board, also known as integrated wood, is composed of multiple pieces of wood splicing, up and down no longer stick splint, due to the vertical wood using a jagged interface, similar to two hands fingers cross butt, so called finger joint board. The finger joint board does not need to paste the splint up and down, the amount of glue is greatly reduced, the plate is very good environmental protection, the finger joint board can basically reach E0 level, is also one of the reasons why we like this plate very much. Finger joint board is often used in furniture, cabinets, wardrobes and other excellent materials.
Dimensions and specifications of finger joint plywood:
Artificial sheet size specifications are generally: 2440mm(length) x 1220mm(width) x thickness. The thickness of the finger joint plywood is generally 9mm, 12mm, 14mm, 15mm, 16mm, 18mm, etc., and the thickest is 25mm.
The purchase skills of finger joint plywood:
1. Finger joint plywood is made of solid wood short lath splicing, the bigger the better, not easy to break.
2. The biggest defect of finger joint plywood is easy to deformation, due to the change of stress in the process of dry shrinkage and wet expansion, resulting in deformation. Therefore, it is very important to reach the moisture content of the finger board, and the palm feels cold.
3. The finger joint plywood is also divided into two types: jointed and unjointed. The finger joint plywood has scar eyes, and the unjointed finger joint plywood does not have scar eyes, which looks more beautiful.
4. Generally speaking, the greater the growth ring of the lath core of the finger joint plywood, the longer the tree age and the better the material. Thousands, years, the finger joint plywood is processed into large diameter logs, board core hardness is good, not easy to deformation.
5. The lath of the finger joint plywood is linked together by adhesive. The adhesive strength of the plate has an important impact on the quality of the finger joint plywood. The splicing gap between the slats is small, without glue, deglue phenomenon.
6. Finger joint plywood is divided into bright teeth and dark teeth, dark teeth are the best, because bright teeth are more likely to appear uneven phenomenon after painting. Of course, the processing difficulty of dark teeth is larger.
The type of finger joint plywood:
1. According to whether there are tree joints on the surface of the plate, the finger joint plywood is divided into two kinds: knot and no knot:
① Knotless finger joint board: after careful selection of materials, the wood without tree joints is selected to make the finger joint board, which looks beautiful.
(2) Knot finger connecting board: splicing short wood will have tree knot, aesthetic degree is worse. However, in some furniture, made of the same specifications of wood, even scar itself is also a kind of decoration.
2. Finger joint plywood according to the splice of the board wood types, common have the following: fir finger joint plywood, rubber wood finger joint plywood, oak finger joint plywood, pine finger joint plywood, camphor pine finger joint plywood, tung finger joint plywood, beech finger joint plywood, etc.
3. According to the load bearing condition, the finger joint plywood can be divided into structural finger joint plywood and non-structural finger joint plywood.
① The finger joint plywood for structure is the bearing component, which requires the finger joint plywood to have enough strength and stiffness. Mainly used in the stadium, concert hall, workshop, warehouse and other buildings of the wooden structure beam, three hinged arch beam is the most common application, which is impossible to achieve in the previous wooden structure
The non-structural finger joint plywood is a non-bearing member, that is, the finger joint plywood commonly used in decoration. Mainly used as furniture and interior decoration materials: such as interior door, window, cabinet beam, column, decorative column, stair armrest, chair bracket, armrest, backrest, sofa, tea table and other bending parts, and decorative materials.
