What are the advantages and disadvantages of high-density boards?
First, the main advantages of density board:
1, density board is easy to finish processing. All kinds of coatings and paints can be evenly coated on the density board, which is the base material for painting effect.
2, density board is a beautiful decorative plate.
3. All kinds of wood veneer, adhesive paper film, decorative panel, light metal sheet and other materials can be glued to the surface of the density board.
4, hard density board punching, drilling, can also be made into sound absorption board, used in architectural decoration projects.
5, excellent physical properties, uniform material, there is no dehydration problem.
6, density board nail holding force is good.
Second, the main shortcomings of the density board:
1, the disadvantage of the density board is that it is not moisture-proof, and it will swell when it sees water. In the use of density baseboard, door cover board, windowsill board should pay attention to the six sides of the paint, so that it will not be deformed.
2, the density board water expansion rate is large, large deformation, long-term bearing deformation than the homogeneous solid wood particle board.
Although the moisture resistance of the density board is poor, the screw will not loosen after tightening, and it is easy to re-fix. However, the surface of the density board is smooth and flat, the material is fine, the performance is stable, the edge is firm, and it is easy to shape, avoiding problems such as decay and insects. In terms of bending strength and impact strength, it is superior to particleboard, and the decorative surface of the board is excellent, which is superior to the appearance of solid wood furniture.
Is high-density board environmentally friendly?
High density fiberboard (referred to as high density board HDF) is a kind of board made of wood fiber or other plant fiber as raw material, applying urea formaldehyde resin or other synthetic resin under the condition of heating and pressurizing. Smooth, when the ambient temperature and humidity change, the dimensional stability is good, easy to carry out surface decoration treatment.
Second, the internal organization structure is fine, especially with dense edges, can be processed into a variety of shaped edges, and do not need to seal the edge directly painted, can achieve better modeling results. The organization structure is uniform, consistent inside and outside, so it can be carved on the surface and processed into a variety of decorative lines, suitable for replacing natural wood as structural materials.
