What is fiberboard What is fiberboard used for?

Fiberboard, also known as density board, is a wood-based board made of wood fiber or other phytochrome fiber as raw material and made of urea-formaldehyde resin or other applicable adhesives. Adhesives and/or additives may be applied during the manufacturing process. It takes about 2.5 to 3 cubic meters of wood to make 1 cubic meter of fiberboard, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs

Second, the characteristics of fiberboard

1, fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., widely used.

2. The disadvantage of fiberboard is that there is a mesh on the back, which causes the surface area of both sides of the board to vary, and the board warps and deforms after hygroscopic due to the difference in expansion force; Hard plate surface hard, difficult to nail, poor water resistance. Dry fiber board avoids some disadvantages, but the cost is higher.

Third, what kinds of fiberboard are there

Usually according to the product density is divided into non-compression type and compression type two categories. Non-compression products are soft fiberboard, density is less than 0.4 g/cm ³; Compressed products are medium density fiberboard (or semi-hard fiberboard, density 0.4 ~ 0.8 g/cm ³) and hard fiberboard (density greater than 0.8 g/cm ³). According to the slab forming process can be divided into wet fiber board, dry fiber board and directional fiber board. According to different post-treatment methods, it can be divided into ordinary fiberboard, oil treatment fiberboard, etc.

1, soft fiber board

Light weight, large void ratio, good heat insulation and sound absorption, mostly used as a covering material in public buildings. After special treatment can be obtained more porous lightweight fiberboard, with adsorption properties, can be used to purify air.

2, medium density fiberboard

Uniform structure, moderate density and strength, good reprocessability. The product thickness range is wide, with a variety of uses, such as furniture materials, TV shell materials, etc.

3, hard fiberboard

The product thickness range is small, between 3 and 8 mm. High strength, 3 ~ 4 mm thickness of hard fiber board can replace 9 ~ 12 mm sawn wood sheet. Used in construction, ships, vehicles and so on.
