Plywood specification
When it comes to plywood specifications, it is necessary to talk about the length, width and thickness of the board. The length and width of the board will be slightly different due to different manufacturers, but generally it will be 1220×2440mm, 1220× 1830mm, 9 15× 1830mm.
The thickness is determined by the number of layers of the adhesive sheet. In addition to the surface plate, the more layers of the inner plate, the thicker the thickness. Plywood can be roughly divided into three categories: 3, 5, 9, 12, 15, 18mm and so on. When processing different furniture, plates with different thicknesses will be used. Of course, their market prices are also different.
Plywood standard
In plywood production, machine splicing has become the development direction of the industry. The transaction target GB/T5849 is widely implemented in the industry with a high degree of standardization.
Formaldehyde emission
The formaldehyde emission of indoor boards can be divided into three grades: E0, E 1 and E2. E0 grade ≤ 0.5mg/L, E 1 ≤ 1.5 mg/L, E2 ≤ 5mg/L ... The quality standard of plywood futures delivery follows the national standard system, and the formaldehyde emission should reach the grade of E1,with the allowable range ≤1.5mg/. Similarly, the E2 level is given a large discount, and participation in delivery is generally discouraged.
(2) Other inspection indexes mainly include appearance, specification, moisture content, transverse static bending strength, immersion peeling performance, surface adhesion and strength.
