[ Chinese wardrobe net ] Currently, the common production of wardrobe plates on the market are fragrant boards, solid wood boards, large core boards, MDF boards, etc. Which kind of board is better for wardrobes? Let's analyze each one together.
The most environmentally friendly is the fragrant board
Hexiang board is made of crop straw and slag as the main raw material, MDI glue and functional additives are applied, and it is made by high temperature and high pressure.
Advantages: It is not only smooth and smooth, the structure is even and symmetrical, the board surface is solid, and the dimensional stability, high strength, environmental protection, flame retardancy and weather resistance are good.
Disadvantages: To say that the shortcomings of the fragrant board, can not be found, modern industrialization, intelligent first-class equipment production fully meets the requirements. If the fragrant cabinet of your home is deformed, it must be unreasonable for the designer!
The second environmentally friendly is the solid wood board
Solid wood panels are panels made from complete wood.
Advantages: Durable, clear lines and relatively environmentally friendly.
Disadvantages: high cost, different wood determines the different characteristics of the board, hardwood is sensitive to the environment and climate, and maintenance troubles.
Application: high-grade building materials and furniture such as solid wood flooring and wardrobes.
Comparison of environmental protection of common boards such as MDF, particleboard, blockboard and large core board:
Large core board
It is made up of two veneers with intermediate glue and splicing wood. The scientific name is blockboard.
Advantages: strong nail holding force, not easy to deform
Disadvantages: Due to the combination of a variety of miscellaneous wood, the density difference is large, easy to produce deformation; high water content; high formaldehyde content; can not be used directly, must be post-treatment.
Environmental testing standards: The amount of formaldehyde released per cubic meter of sheet should be less than or equal to 150 mg.
Even if it has such defects, in the current home improvement project, whether it is the door, the door cover, the window cover, the heating cover, the locker, the partition cabinet, etc., the most common one is the large core board.
Medium density fiberboard
In China, it is made up of three main remnants of agriculture or sub-small fuelwood, which are made by hot grinding, drying, sizing, paving, hot pressing, post-treatment and sanding.
Advantages: excellent physical properties, uniform material, no dehydration problem, no moisture deformation; the surface of the tri-hydrogen ammonia finish has moisture, corrosion resistance, wear resistance, high temperature resistance, etc., no post-treatment, formaldehyde content low.
Disadvantages: The nail holding force is worse than the particle board. If the screw is loose after screwing, it is difficult to fix because the strength of the MDF is not high.
Particle board (particle board)
Particleboard, also known as particle board, particle board, bagasse board, scraps made of wood or other lignocellulosic materials, artificial board after adhesive application under the action of heat and pressure, also known as particle board.
Advantages: good nail holding power, good lateral load-bearing capacity, and lower cost than medium-density board. Although the formaldehyde content is higher than the medium density board, it is much lower than the large core board; the price is relatively cheap.
Disadvantages: It is easy to cause violent teeth when cutting boards, so some processes require higher processing equipment; it is not suitable for on-site production.
Environmental testing standards The amount of formaldehyde released per cubic meter of sheet should be less than or equal to 40 mg.
The environmental performance of the board depends on its formaldehyde emission, and the formaldehyde emission is determined by the production process of the board. The source of formaldehyde is the adhesive in the board. The most important factor is the variety of the adhesive and the amount of glue used.
When the same size of the three boards is the same type of glue, the amount of glue used determines the environmental performance.
The blockboard (large core board) adopts the glue coating process, which has the largest amount of glue and the worst environmental protection;
Both the particleboard and the MDF are sprayed, the colloid is evenly distributed, and the amount is small. Compared with the two, the MDF is slightly lower than the particleboard.
So the order of good and bad comes out? The MDF is the best, the particle board is second, and the blockboard is the worst.
