Many homemakers have “environmental protection†for their own materials. What kind of eco-plate, zero-aldehyde board, Australian solid wood board, fragrant board, MDF solid wood particle board, etc. are so strange that the environmental performance is blown up:
“Buy furniture must buy health, so plate environmental protection is especially importantâ€
"E0 level board is definitely better than E1 level"
“The fragrant board uses MDI glue, no formaldehydeâ€
...
Right, you are right, but it is too exaggerated!
Do you know that apples don't eat apples when they spray pesticides?
Do you know that Coke does not drink cola?
...
"Cup bow and snake shadow" can't be the norm in life, so we say that everything is there. As the owner of unfamiliar materials, how to choose a good product from the market, today Xiaobian take two of the plates to compare and see, is the solid wood particle board or MDF good?
MDF
The MDF is also the MDF MDF, which is made from wood fiber or other plant fibers.
The plate making process (you don't need to know too much here) is basically an artificial board made by breaking the material, separating the fibers, drying the urea-formaldehyde resin or other suitable adhesive, and then hot pressing.
Advantages: The material is relatively thin, and the cut surface will be well sealed when it is edged, so it is not easy to open the glue. It is easy to press into various shapes and it is easy to make a shape, so there are usually more door panels or back panels.
Disadvantages: Because the substrate is a powder, it uses more glue than the particle board, which is more likely to cause environmental problems. Secondly, due to the high glue content of the MDF, the internal structure space is small, and the moisture resistance is poor. The density of one piece is soaked in water for 24 hours. After ten hours, it is obvious that the MDF rises and deforms.
Particle board
Particleboard has two very village names, called “particle board, bagasse boardâ€. This kind of board is made of wood or other non-wood plants into shavings or scraps. (This is the biggest difference between wood and grain boards! Core wood is not granular, but shaved
Oriented particle board, the surface can be seen clearly
The plate making process (you don't have to know too much here) applies a hot pressed sheet of adhesive and other additives. According to the plate structure, it is divided into single layer, three layers, and gradual structure particle board.
Many people may not know that the particle board is the "original board" (different from the "ecological board"). The predecessor of the "hexiang board", the evolution of the latter two sheets in the glue, the process has been improved This is why the latter two are more environmentally friendly. For example, the “original plate†is made of crop straw as the main material, combined with MDI glue, and the surface is made of imported food grade coating film, which is made through a series of processing techniques.
It turned out to be this material
advantage:
1. The particleboard is insulated and sound-absorbing, and has good sound absorption and sound insulation properties.
2. The inside is a granular shape with a cross-displacement structure, the performance in each direction is basically the same, the lateral load-bearing capacity is good, and the inside is a granular shape with a cross-displacement structure. Therefore, the nail holding power is good, and the nails and screws can be nailed. These machinable properties are significantly better than MDF.
3, the surface of the particle board is smooth, the texture is realistic, the weight is uniform, the thickness error is small, the pollution resistance, the aging resistance, the appearance are beautiful, and various veneers can be carried out.
4. In the production process of particleboard, the amount of glue used is small (the content of solid wood particle board is generally less than 5% in the use of adhesive), and the environmental protection coefficient is higher than that of fiberboard.
5, warp deformation is small, dimensional stability is good, high strength, good stiffness, hanging heavy clothing is not easy to bend. The wood-based panels currently used in the European furniture market are mainly solid wood particle boards, and most of the domestic manufacturers use solid wood particle board as the cabinet substrate.
Disadvantages:
1. The internal structure is granular, it is not easy to be milled, and it is difficult to make curvature and shape.
2. It is easy to cause the phenomenon of violent teeth when cutting boards. Therefore, some processes have higher requirements on processing equipment and should not be produced on site.
National environmental standards
The two standards E1 and E2 were produced in Germany and were developed by EGGER, and then cited as European standards.
You can definitely find that the "E" is also the abbreviation of the English word "Europe" in Europe.
So what is the E0 standard?
There is a saying that it is actually "Chinese characteristics". In Europe, the highest standards are E1 and E2. Another way of saying this is that only the Finnish and Japanese countries in the world implement the E0 standard. The household products that meet this standard are the top international environmental protection products. In China, the highest industry standard for wardrobes and laminate flooring is E1, and the national standard for cabinet industry is E2. So, when the friends enter the store, there is no need to entangle the problem of E0. The plates of E1 and E2 can be used at home!
1. Test method——Dryer method: E0 level formaldehyde emission amount ≤0.5mg/L, E0 board can be directly used for indoor board. The E1 grade formaldehyde emission is ≤1.5mg/L, and the E1 board can be directly used for indoor boards. The E2 grade formaldehyde emission is ≤5.0mg/L, which must be allowed to be used indoors after finishing treatment.
2, test method - perforation extraction method: E0 formaldehyde emission amount ≤ 3mg / 100g, E0 plate can be directly used for indoor panels. The E1 grade formaldehyde emission is ≤9mg/100g, and the E1 board can be directly used for indoor boards. E2 formaldehyde emission ≤ 30mg / 100g, must be used in the interior after the finish treatment.
In order to meet different needs, the selection of plates should also be “adapted to local conditionsâ€. For example, the backboard/door panel uses MDF, which can not only utilize the advantages of good flatness of the MDF, but also easy to shape, to ensure that the product shape can be more beautiful, bearing plate The use of particleboard or solid wood particle board is more durable and can create an environment-friendly living environment.
