Wheat straw board is a kind of artificial composite board with excellent performance. Rice straw and wheat straw are processed into natural degradable and pollution-free composite board to make cutting board.
1, the hardness of wheat cutting board is close to steel, and its high density makes it have strong antibacterial effect, which is not easy to leave marks and easy to clean, and solves the problem of mold residue from the root.
2. Wheat straw chopping block is a kind of plant fiber chopping block, which contains a certain amount of water. It doesn't matter if you live in a wet coastal area. If you live in the dry inland and north, please cover it with a wet cloth after use to avoid fiber shrinkage and cutting board deformation. If it is dehydrated and deformed, don't worry, just cover it with a wet cloth and it will recover.
3. The adhesives used in wheat products are natural adhesives, which are extracted from various plants and have no side effects.
Extended data
I. Technical indicators
Wheat straw board has the characteristics of no formaldehyde release, good waterproof performance, uniform section density, good reprocessability and so on, and its conventional mechanical properties are also excellent.
Performance comparison test items of wheat straw board and particleboard: density (g/cm3) of particleboard wheat straw board is 0.60, water content (%) is 6.0, static bending strength (Mpa) 15 30.0, internal bonding strength (MPa) is 0.300.60, water absorption thickness expansion rate (%) is 3.3, and nail holding force on vertical board surface (3.3).
Second, the practical application
1. Straw tiles, straw boards and ecological doors are made of agricultural waste fibers and crop straws. For example, the wheat straw board with directional structure is formed by pressing and can be widely used as the bottom lining of walls, roofs and floors. It is one of the most widely used materials in frame structure buildings, which can not only insulate against heat, sound and moisture, but also reduce the use of steel, cement and bricks with high energy consumption and reduce deforestation.
2. The energy consumption of raw materials and production process of wheat straw board is lower than that of wood particleboard, and its performance is far superior to that of wood particleboard, so wheat straw board has strong market competitiveness.
