Let's talk about the foundation board first. The foundation board is the basic material that people often say, mainly including particleboard, joinery board, integrated board, plywood and so on. Environmental protection board is classified according to the environmental protection grade of board, mainly including E 1, E0 and ENF grades.
Let's start with the basic disk.
Particleboard Particleboard is a kind of particleboard. Particle board is made of wood particles, which retains the essence of natural wood. The surface is smooth and delicate, the stability is good, and the material is uniform, which belongs to the environment-friendly substrate.
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 board, covered with two or more layers of plywood on both sides and pressed with glue. Blockboard has the characteristics of good screw grip, high strength, firmness, sound absorption and heat insulation.
Integrated board, also known as glued wood or finger joint board, is made up of several wooden boards, and the upper and lower plywood are no longer glued. Because the vertical board adopts serrated interface, which is similar to the cross docking of two hands and fingers, it enhances and improves the strength and appearance quality of wood, so it is called finger joint board. Because there are few joints and less glue used, the environmental protection coefficient is relatively high. This is easy to process.
Multilayer board, also known as plywood, is to rotate logs into veneers and combine blanks into three or more layers according to the principle of crisscross, usually odd-numbered veneers. It is the earliest wood-based panel material used for home improvement. High compressive strength, not easy to crack, deform, expand and dry at various temperatures. Environmental protection: the multi-layer board is all natural wood, which can adjust the indoor temperature and humidity and is convenient to install.
Let's talk about environmentally friendly plates. According to last year's new national standard for wood-based panels (GB/T 39600-202 1 Classification of Formaldehyde Emission from Wood-based Panels and Their Products), they are E 1 ≤0. 124mg/m? ; E0 grade ≤0.050mg/m? ; ENF grade ≤0.025mg/m? ;
Environmental protection board has a wide range of applications, which can be basic board, decorative board and functional board. Therefore, when you buy plates, you can choose plates with higher environmental protection level, which is more secure for the safety of the living environment.
