1, blockboard
The joinery board is made by gluing and splicing two veneers in the middle. The large core board is made by processing wooden boards into strips with certain specifications, splicing them with a splicing machine, and then pressing them with a cold and hot press.
Advantages: the large core board has the characteristics of good nail holding power, high strength, strong quality, sound absorption and heat insulation, and the blockboard has low moisture content and is easy to process.
2, multilayer solid wood board
Multi-layer solid wood board is made up of three or more layers of single boards and thin boards bonded by high temperature and high pressure. Its main base material is criss-crossing multi-layer plywood, which is made by cold pressing, hot pressing, sanding and curing.
Advantages: In the pressing process, the multilayer solid wood board has the advantages of stable structure, difficult deformation, high strength, good internal quality, good flatness and stability due to the vertical and horizontal gluing of single boards and high temperature and high pressure pressing.
3. Ecological paint-free board
Eco-paint-free board is a decorative board made by soaking different colors or textures of paper in melamine resin glue, then drying to a certain curing degree, laying it on particleboard, moisture-proof board, medium density fiberboard, plywood, joinery board or other solid wood boards, and hot pressing.
Advantages: the eco-board paint-free board has the characteristics of beautiful and gorgeous surface, environmental protection and health, convenient construction, scratch resistance, wear resistance and moisture resistance.
Disadvantages: the eco-board requires high cutting and edge sealing technology, otherwise it is easy to break the phase; In addition, because the products on the market are mixed, and the prices vary greatly, it is difficult to choose, so it is necessary to strengthen the identification of authenticity when choosing.
4, solid wood particle board
Solid wood particleboard is an artificial board made by cutting various branches, small-diameter wood, fast-growing wood and other substrates into chips with certain specifications, then drying them, mixing them with aldehyde-free adhesive, hardener and waterproof agent, and pressing them at high temperature and high pressure.
Advantages: uniform internal texture, better nail holding power, bending resistance and stability than ordinary particleboard and powder density board. In addition, the environmental protection performance of solid wood particleboard is better than that of MDF.
Disadvantages: solid wood particle board will use a lot of glue when making and processing, so the environmental protection sheet is relatively poor; In addition, its flatness is poor, so it is difficult to make some arcs or shapes;
So how to choose and judge the environmental protection plate of wardrobe?
1, depending on the certification and environmental protection level?
Products with higher environmental protection level can be selected according to the requirements of standards. At the same time, you must read the certification and report carefully when choosing products, which are the most intuitive display of the environmental protection level of products.
In addition, the environmental protection grade is an authoritative index to judge the pollution of plates. According to the new national standard of wood-based panels (GB/T 39600-202 1 Classification of formaldehyde emission from wood-based panels and their products), the formaldehyde emission from indoor wood-based panels and their products is clearly divided into three grades according to the limited value, namely, E 1, E0 and ENF:
E 1 grade ≤0. 124mg/m? .
During the implementation period, the plates certified by E 1 can be used for interior decoration.
E0 grade ≤0.050mg/m?
ENF grade ≤0.025mg/m? The new national standard ENF level, that is, the level without aldehyde addition, will become the most stringent environmental protection standard in the world.
The new national standard is applicable to all kinds of indoor wood-based panels and their products, such as fiberboard, particleboard, plywood, joinery board, recombined decorative materials, laminated veneer lumber, laminated veneer lumber, wood-based panels, wood wallboard and wooden doors. In China, all the boards with E 1, E0 and ENF grades can be called environmental protection boards. ?
2. See how to use glue?
When choosing plates, we should also pay attention to the glue used in plates. There are two kinds of glue: aldehyde glue and aldehyde-free glue. Aldehyde glue is phenolic resin glue and urea-formaldehyde resin glue respectively; Aldehyde-free glue is soybean glue and MDI glue. There are different kinds of glue. Relatively speaking, MDI glue is more environmentally friendly, but it cannot completely achieve zero formaldehyde. ?
3. Look at the edge sealing process?
Edge sealing technology can not be ignored when selecting plates. The quality of edge sealing can be said to determine the formaldehyde emission of the plate, and the formaldehyde emission with good edge sealing will be much less, and vice versa. Moreover, good edge sealing can avoid household moisture and prolong the service life of furniture. ?
4. Look at the brand?
Brand represents strength, big brands pay special attention to product quality, and at the same time, big brands will be supervised by more people.
If you are not very clear about the choice of plate, then it is best to choose brand products, at least in terms of quality, but also more open and transparent.
In addition, the brand has a very important point: value-added service, ubiquitous stores, perfect service system and timely after-sales maintenance.
The above is what Xiao Ye shared about the types of wardrobe plates and how to choose them. I hope I can help you.
