[ Chinese wardrobe net ] At present, the whole floor panel of the market is mainly solid wood particle board, MDF, solid wood board and fragrant board, among which solid wood particle board and MDF occupy more than 80% of the market share, solid wood board and fragrant board a bit less. Regardless of the type of sheet, the thickness of the panel of the overall wardrobe should preferably be 18 mm or more.

Solid wood board: It is made of solid wood logs after processing.

Wood-based panels: panels that are manually pulverized or layered with wood or other materials, then added with an adhesive, then paved and artificially bonded by high-temperature hot-pressing. Such a wood-based panel is a man-made product having a solid wood property that has been completely destroyed by the physical structure of wood or the like as a base material. Solid wood particle board, MDF board and Hexiang board belong to this category.

1, solid wood particle board (particle board)

It is a wood-based material made of wood or other lignocellulosic material. It is a synthetic board that is glued under the action of heat and pressure. It is a board produced by the particleboard process, which is a kind of homogenized particle board.

The solid wood particle board has the advantages of superior environmental performance, strong decorative performance, non-deformation of warpage, strong nail holding force and good processing performance.

2, MDF (medium density fiberboard)

MDF is a type of MDF, including long-fiber boards and short-fiber boards. An artificial board made of wood fiber or other vegetable fiber, which is crushed, separated by fiber, dried, and then urea-formaldehyde resin or other suitable adhesive is applied, and then hot pressed. The density is generally in the range of 0.5 to 0.8 g/cm 3 and the thickness is generally 3 to 30 mm.

The fiber structure of the sheet is uniform, and the bonding strength between the fibers is high, so its static bending strength, plane tensile strength, and elastic modulus are good, but the holding screw force is weaker than the particle board.

3, the fragrant board

Hexiang board is made of crop straw and straw as the main raw material. It is made of MDI glue and functional additive. It is made of high temperature and high pressure. It is not only smooth and smooth, the structure is even and symmetrical, the board surface is solid, and it has good dimensional stability and high strength. It is environmentally friendly, flame retardant and weather resistant. It also has excellent processing properties and surface decoration properties. It is suitable for various surface decoration treatments and mechanical processing, especially for profiled edge processing. Can be widely used to replace wood-based panels and natural wood. It has the advantages of environmental protection and no release of formaldehyde, but the price is higher.

Evaluation guide example:

Observing the cross section of the fragrant board, it is found to be a dense lamellar structure, which is slightly rougher than the common MDF and particle board on the market. This is because the fragrant board is made of natural straw fiber, although it is rough but the surface of the straw fiber There is a large amount of natural wax, so the fragrant board is not easy to absorb water, and the recovery rate after the tide is better than the ordinary board on the market, which can be used to build the bathroom cabinet.

Environmental standards for plates

E0, E1, and E2 all refer to an environmental standard for formaldehyde emission limit. The first two standards, E1 and E2, were produced in Germany, developed by EGGER, and then introduced as European standards. The highest standards in Europe are E1 and E2. E0 is produced in Japan and is the most demanding environmental standard. It is equivalent to E1 and E2 in Europe. It is based on the content of harmful substances such as formaldehyde in the board.

E0 means: the amount of formaldehyde released by 0.5 mg/L or less; E1 means: the amount of formaldehyde released by 9.0 mg/100 g or less; and E2 means the amount of formaldehyde released by 30.0 mg/100 g or less.

The country has not yet officially released the national standard for the E0 level. At present, the so-called E0 standard is mostly a convention in the industry. Specifically, at the time of purchase, smell the samples in the store for smells, and ask the merchant to show the inspection report of relevant environmental standards.
