How families can not do without the plate decoration. As a material that is in direct contact with people, one of the most important requirements for sheet metal is environmental protection. Nowadays, many sheet metal brands on the market are known as E0 and zero formaldehyde. Some consumers also do not know how to choose environmentally friendly sheet because of market confusion. Therefore, the next Mi Xia Furniture Xiaobian introduced several environmental board rankings .
Green sheet rank one, blockboard
Generally called Daxin board. It is a man-made board made of urea-formaldehyde resin adhesive, which is composed of upper and lower layers of plywood and middle small pieces of wood. The center is a core made of natural wood. The two sides are glued with very thin veneer. The core board is one of the most important materials in the decoration. Blockboard is a large number of decoration materials used in the interior decoration of urban and rural residents in China. It can be used as furniture, wood doors and window covers, heating covers, curtain boxes, etc. Its waterproof and moisture-proof performance is better than particleboard and medium density boards. However, due to the use of urea-formaldehyde resin adhesives, the indoor environment caused by the decoration has caused potential formaldehyde pollution.
Green sheet ranked second, MDF
Including indoor decoration pollution and all kinds of fiber board and particle board used in furniture manufacturing, also known as particle board, it is the processing of wood processing residues, small diameter wood, wood chips and other materials cut to a certain size of the debris, after drying, mixed with rubber material , hardeners, waterproofing agents, etc., pressed under a certain temperature, pressure made of a man-made board. Some bamboo, straw, bagasse and other fibers are also used. After using melamine veneer, these types of wood-based panels are also called melamine boards. It is estimated that the amount of formaldehyde-containing urea-formaldehyde resin adhesive required for producing per cubic meter of density board is generally 200-250kg.
Environmental plate rank three, multi-layer fingerboard
It mainly includes various multi-layer solid wood fingerboards produced using urea-formaldehyde resin adhesives. Generally, the multi-layer fingerboard is three layers, so that there will be two layers of adhesive in the middle of the three layers. However, because the "finger joints" of various fingerboards are exposed in the air, the formaldehyde is more easily volatilized.
Green sheet ranked fourth, plywood
It is a wood-based panel that has been cooked, softened and cut into large sheets along the annual rings, dried, sorted, glued, formed, hot-pressed, and sawed. The number of layers of plywood wood chips should be odd, usually 3 to 13 layers, and the fibers of adjacent wood chips should be perpendicular to each other when glued. Plywood is mainly used in the decoration and furniture manufacturing with solid wood materials, density boards, blockboards and fingerboards and other materials. The main production process is the use of urea-formaldehyde resin adhesives to bind three-, five-, seven-, and nine-story wood veneer panels.
Green sheet ranked fifth, veneer panel
The veneer is a kind of surface material that is used for interior decoration or furniture manufacturing. The natural wood or the technical wood is cut into thin slices of a certain thickness, adhered to the surface of the plywood, and then hot-pressed. Glue is used to affix the wood-based panels used to decorate furniture surfaces on thin MDF boards and chipboards. Can not be used alone, can only be attached to blockboard, plywood, fir fingerboard above.
