Plywood is commonly referred to as fine-core board in the industry. Multi-layer board is a three-layer or multi-layer board-like material that is made of wood segments peeled into veneer or wood planing into veneer, and then glued with adhesive. It is usually made of odd layers of veneer, and the fiber direction of adjacent layers of veneer is vertically glued.
Plywood specification:
1. The length is 2440 mm, the width is 1220 mm, and the thickness is 2.7 mm, 3.3 mm, 4.5 mm, 5.5 mm, 6 mm... 18 mm is commonly used in 6 specifications of 3 cm plate, 5 cm plate, 9 cm plate, 12 cm plate, 15 cm plate and 18 cm plate (1 cm is 1 mm). Of course, there are also 21 cm and 25 cm, and the thickness can be basically produced according to different requirements.
2. Plywood for building membrane: 1830mm long, 915mm wide, 3mm and 5mm thick.
Plywood multilayer board is weather-resistant and boiling water resistant plywood, so it has the advantages of durability, high temperature resistance and steam treatment. The second type of plywood is water-resistant plywood, which can be soaked in cold water and hot water for a short time. The third type of plywood is moisture-resistant plywood, which can be soaked in cold water for a short time and is suitable for indoor use at room temperature. For furniture and general building purposes. The fourth type of plywood is non-hygroscopic plywood, which is used at room temperature. It is mainly used for testing and general purpose plywood, including basswood, ash, birch, elm, poplar, etc.
Use of plywood:
The characteristics of plywood, such as small deformation, large size, convenient construction, and good transverse tensile properties, make its application fields more and more extensive,
1. Furniture manufacturing, such as cabinets, cabinets, tables, chairs, etc;
2. Interior decoration includes ceiling, wall skirt, floor lining board, etc;
3. Vehicle and ship manufacturing and other packaging industries.
