Today, the rapid development of business, laminated plywood, laminated MDF and laminated particle board have been welcomed and used in a wide range. Below I will tell you one of the relevant information.
What is laminated ?
What is plywood ?
Type of laminated plywood
Laminated plywood application
Laminate is a thin surface wood or wood veneer. It looks wider. It is plywood but has a protective plastic layer on one or both sides. Laminates are used to replace plywood due to their impact resistance, weather resistance, humidity resistance, cold resistance (ductility) and chemical resistance.
Laminate layers (called veneers) are bonded to adjacent plywood. The grains are at right angles to each other for greater power. The plastic layers added for protection vary in composition, thickness, color and texture depending on the application.
Plywood is made from thin wood chips bonded together. These individual sections are referred to as wood veneers which are formed by stripping the wood from the tree. Most of the veneers are made by rotary cutting. Rotary cutting means that the logs of the wood are mounted on the machine and rotated along its longitudinal axis, while the cutters are stripped from the logs. The veneers thus obtained are then placed on top of each other to form a layer. Each individual layer is also referred to as a layup. An adhesive such as phenolic resin or urea-formaldehyde is then applied to each of the layers of the adhesive, and the layers are then sent together to a hot press and laminated together under high pressure. The laminate was completed.
In order to make full and effective use of forest resources to develop plywood production and the best use of materials, China's new national standard (draft report) is divided into decorative plywood. Panels coated with clear paint (based on surface requirements). Coated furniture), sewing machines and tables of various electrical boxes, etc.), decorative plywood (building, furniture, vehicle and ship decoration materials), plywood (for packaging, filling and other uses) and veneer plywood (building, furniture ) As a high-quality finish for automobiles, ships, etc., the plywood type can be further subdivided by adhesion:
(1) Class I (NQF) - weather resistant, boiling water resistant plywood. This type
Plywood is durable, resistant to boiling or steaming and can be used outdoors.
(2) Class II (Ns) - water resistant plywood.
It can withstand cold water or short-term hot water impregnation, but is not resistant to boiling.
(3) Class III (Nc) - non-durable plywood.
Plywood is one of the most common facing materials. It is one of three wooden boards. It can also be used for airplanes, ships, trains, cars, buildings and boxes. Generally, the veneers are vertically bonded in the direction of the texture of adjacent layers. Usually, the front panel and the inner panel are symmetrical on both sides of the middle layer or core. The veneer obtained from the veneer laminated on the wood particles is heated or pressurized without heating. The number of layers is usually odd and even. The difference in physical and mechanical properties between longitudinal and lateral directions is small. General plywood is plywood, plywood, etc. Plywood can improve the use of wood and is the main method of saving wood. The general requirements for length and width are 1220 × 2440 mm. General thickness requirements: 3, 5, 9, 12, 15, 18 mm, etc. The main wood types are eucalyptus, hawthorn and willow. Poplar, elm, etc.
