Commercial plywood is a significant branch of man-made boards and the largest type of board produced and sold among the three major board in the wood industry: plywood, particleboard, and fiberboard. With the further improvement and enhancement of plywood’s superior qualities, it has become increasingly popular in modern home furnishing.
Particle boards may not necessarily exceed formaldehyde standards, but commercial plywood will certainly not exceed formaldehyde standards.
first point: raw materials
From an objective perspective, the raw materials for particle boards are wood chips, residues, broken particles from old doors, windows, old floors, and even broken waste cartons, etc. The cost of such raw materials is low and the quality is difficult to control, so Environmental protection levels are difficult to control. Regular manufacturers will choose real wood chips and wood residues, but some manufacturers even use raw materials such as old floors with soil, sand, and formaldehyde seriously exceeding the standard. The raw materials of commercial plywood, especially marine plywood, are large-diameter wood. Although the cost has increased, it can ensure that the wood used is the best, which makes it easier to control in terms of environmental protection.
Point two: adhesives
Point two: adhesives. We all know that whether furniture is environmentally friendly depends on the board, and whether the board is environmentally friendly depends on the adhesive. The glue used in particle board is generally urea-formaldehyde glue, which is a kind of glue composed of urea and formaldehyde. It is polluting and cheap. It is difficult to improve the environmental protection level of such finished particle board products. Currently, the highest grade particle board in China can only reach the E0 level, which cannot meet the needs of indoor life at all. Excessive use will lead to excessive formaldehyde.
point three: certification
which can also be said to be testing standards. At present, the particle board furniture on the Chinese market, whether it is the E0 level reported by the merchants or the E0 level promised by the manufacturer, is basically hovering at E0. It can be said that the vast majority of them do not meet this requirement. Therefore, there is a gap between reality and ideal.
The raw material of commercial plywood is solid wood
Most of the raw materials used in particle board come from logging and processing residues, as well as small-diameter wood (diameter less than 8 cm) materials.
Dimensions are more stable
The production process of commercial plywood is made by pressing horizontal and vertical layers of veneers. The fiber directions of adjacent layers are arranged perpendicular to each other, which improves the anisotropic shortcomings of wood formed under natural growth conditions, improved dimensional stability. For finished furniture, the service life is longer.
Not easy to deform or crack
Commercial plywood is made of multi-layer veneers arranged in a criss-cross pattern as the base material, and high-quality wood is selected as the panel. After being glued, it is made through high temperature and high pressure in a hot press. Board deformation and cracking are mainly caused by moisture content and other factors. Commercial plywood can strictly control the moisture content of each veneer during the production process, so the quality of the finished board is more guaranteed. It is not easy to deform and crack, and the dry shrinkage and expansion system is extremely small. It solves the two major defects of deformation and cracking of solid wood panels from the aspect of internal stress.
High strength and good flatness
The unique production process and raw material selection of commercial plywood determine its unique quality. Commercial plywood uses multi-layer veneers arranged in a crisscross pattern as the base material. In the current production process, the veneers are ground and matched diagonally. The jointing process (the initial splicing, later seaming, and now the oblique grinding and lap joint, the process is constantly improving), and then made through several processes such as cold pressing, hot pressing, and sanding, ensuring high strength and grip. It has the characteristics of good nailing force and high flatness.
The plate format is large
Commercial plywood is made by rotary cutting logs into veneers and then arranging larger-area boards in a staggered manner. Theoretically, the format of commercial plywood can be infinite, but in practice, it is produced according to national standard sizes. This is very different from other boards, such as other particle boards and MDF, which are completely made of discarded scraps. Even if they are combined again with adhesives, they are not as good as original wood such as commercial plywood boards. This also solves the shortcomings of insufficient format of solid wood panels that are affected by the age and growth rate of the wood.
Easy to process and produce finished products
Commercial plywood has precise thickness, length and width suitable for most furniture, and is close to solid wood. It has no special requirements for processing machinery, processing saw blades, processing technology, etc. It is easy to process and easy to shape. An ordinary carpenter can also use commercial plywood to make a beautiful and practical wardrobe.
Good quality and cost-effective
Commercial plywood is the man-made board closest to solid wood. However, it is stronger, tougher, larger in area, less prone to deformation and cracking than solid wood, and has better quality. However, the actual price is lower than solid wood, and the effect is close to that of solid wood, and it is cost-effective.
More surface selectivity
Commercial plywood has good flatness and can be directly used for veneer. If consumers have other favorite colors, they can be directly produced for veneer production, which perfectly meets consumers’ customized services for various designs and colors.
