Some friends may have heard of the finger-joined board for the first time. So what is the material of the finger joint? What are the advantages and disadvantages of finger joint board? Let me introduce you to the following.

What is a finger board

The use of finger joint board

1. The use of finger joint board for structure

The structure uses finger-joined plates as building components. The most important feature of wallpaper powder is that although the component has a large cross-section and is a combustible material, the risk of collapse in a fire is extremely small, and the evacuation time is long. It will not be damaged due to collapse, so the structural finger joint plate can be used to produce various shaped bearing beams, columns, frames, etc., and has been widely used in stadiums, concert halls, factories, warehouses, bridges and other buildings.

2. Use of non-structural finger joint board

Non-structural finger joint plates are mainly used to make components with less stress. In the furniture industry, it is mainly used as large-format components such as furniture panels, door panels and side panels, cabinet partitions, office boards and drawer bottom panels, etc.; small-format components such as drawer panels, side panels and cabinet doors and chairs Brackets such as brackets, armrests, backrests, sofas, coffee tables, etc. Wallpaper powder is mainly used in the decoration industry for stair side panels, steppers, floors and wall decoration panels.

The finger jointing board is a solid wood plate spliced ​​from multiple wooden boards. Its upper and lower non-stick plywood, so the amount of glue used in production is very small, the material is more environmentally friendly, so it is more and more popular. Because of the zigzag interface between the vertical boards, it is similar to the shape of the cross-docking of two fingers, so it is called the finger joint board. The finger joint plate is an environmentally friendly plate, and its texture looks very natural, giving people a feeling of returning to nature.

There are two types of finger joints: knotted and jointless. There are scars on the jointed jointed joints, but no scars on the jointed jointed joints. It looks more beautiful, so some people use finger joints directly. Use the board to make furniture, no need to affix any decorative panel on the surface, so that it has personality and saves money.

Fingerboard identification

The finger joint board is a kind of man-made board spliced ​​with wooden strips about five centimeters wide. Some people do not understand the finger joint board. Xiaobian teaches you how to easily identify the finger joint board here. The identification of finger joint plates mainly depends on the annual rings of core materials. The finger joint plates are mostly made of Chinese fir. The annual rings are more obvious. The larger the annual rings, the longer the tree age and the better the material of the finger joint plates.

Another way is to look at the tooth marks. Finger joint plates are usually divided into exposed teeth and dark teeth. Among them, dark toothed finger joint plates are the best, because exposed tooth finger joint plates are more prone to unevenness after painting. Of course, the processing of dark teeth is more difficult. The harder the wood, the better the quality of the finger joint board, because its deformation is much smaller than that of the ordinary board, and the pattern is more beautiful.

The advantages of finger joint board

1. The surface of the finger joint board is generally painted with clear water paint. The environmental protection effect of the paint seal is relatively good, and it can basically reach the E0 level. Therefore, the furniture made of the finger joint board is more environmentally friendly and healthy.

2. The current price of finger joint board is relatively cheap in the market, generally 110-180 yuan, compared with some good wood board, finger joint board is not much more expensive.

Disadvantages of finger joint board

1. Fingerboard furniture is not real solid wood furniture in the traditional sense, but flat wood furniture is, so fingerboards do not have the durability of traditional solid wood furniture. In addition, the finger joint board is generally made of pine, cypress and other raw wood materials, the material is not good, and its drying time is generally shorter, the water content is also larger, it is easy to cause deformation and cracking.

2. The finger joint boards commonly used in modern life are divided into single-layer finger joint boards and three-layer finger joint boards. The method adopted by the three-layer finger joint board is naturally much stronger than the single layer finger joint board in terms of resistance to deformation. So when you choose a finger joint board, remember to choose a three-layer finger joint board, which is more durable.
