GB/T 39600-202 1 Classification of Formaldehyde Emission from Wood-based Panels and Their Products and GB/T 39598-202 1 Guidelines for Indoor Load Limits of Wood-based Panels Based on Extreme Formaldehyde Content were formally implemented.
According to the standard, the formaldehyde emission of indoor wood-based panels and their products is divided into three grades according to the limited value, that is, E 1 grade (≤ 0. 1.24 mg/m? ), E0 grade (≤0.050mg/m? ) and ENF grade (≤0.025mg/m? )。
Environmental protection plate recommendation
Finger joint board: made of all wood, also known as integrated board, integrated board and finger joint board. The finger joint plate is made up of several plates, and there is no need to press the splint up and down. Because of the serrated interface between the vertical plates, it is similar to the cross docking of two fingers.
Advantages: Most of them have the unique fragrance of natural wood and have no pollution to the environment. They are high-quality plates for making furniture and decorating houses. Very decorative, environmentally friendly, durable and practical.
Solid wood laminate: Solid wood laminate is also called plywood. It is a main way to save wood by cutting wood segments into veneers or sheets and then bonding them with adhesives.
Advantages: the utilization rate of wood is improved, the size is more stable, it is easy to process, the decoration is strong, the compression resistance is strong, and the shrinkage and expansion coefficient is extremely small. Environmental protection is higher than particleboard, and the price is more affordable.
Blockboard: Blockboard refers to a kind of special plywood based on the production of plywood, which is spliced with wooden boards or hollow boards as the core, covered with two or more layers of plywood on both sides and pressed with glue.
Advantages: joinery board screws have good grip, high strength, strong quality, sound absorption and heat insulation.
