What environmental protection materials are there?
1, high density fiberboard
High density fiberboard is one of the green environmental protection materials. The material of high density fiberboard is uniform, and there is no dehydration problem. The material is exquisite, the edge is firm, the modeling is easy, and the problems such as rot and moth-eaten are avoided. High bending strength and impact strength.
2. Melamine board
Melamine board is a common green environmental protection material in the market. Its color and texture are made by soaking in melamine resin glue, then drying to a certain curing degree, spreading on the surface of particleboard, medium density fiberboard or hard fiberboard, and hot pressing.
Step 3 splint
Plywood is made of three or more odd layers of veneer by adding glue. It has good strength and toughness, strong nail grip, easy processing and insulation, and can make up for some natural defects of natural wood.
4. Core plate
Particleboard is a board pressed by adding glue or other auxiliary materials, which has good sound absorption and sound insulation performance. It can be used as sound-absorbing building components such as sound-insulating wallboard doors. The expansion rate of plate is low, and the error of plate thickness is small.
5, large core board
Large core board is widely used, and its main characteristics are low density, high strength, sound absorption and heat insulation, simple processing technology and good nail holding ability, so it is deeply loved by consumers.
What kinds of environmentally friendly plates are there?
1. Solid wood board is one of the environmental protection furniture boards. Solid wood boards are made of all wood. These plates are durable and natural in texture, making them the best choice for making furniture. However, due to the high cost and high construction technology requirements, this kind of plate has not been widely used in production. Solid wood boards are generally classified according to entity names, and there is no unified standard specification. In addition to the floor and door leaves will use solid wood, commonly used plates are artificially processed wood-based panels.
2. MDF is one of the environmentally friendly furniture boards. Density board, also known as fiberboard, is an artificial board made of wood fiber or other plant fiber and urea-formaldehyde resin or other suitable adhesives. According to the different density, it can be divided into high density board, medium density board and low density board. The MDF is soft, impact-resistant and easy to reprocess. However, because the national standard of high-density board is several times lower than the international standard, the use quality of high-density board in China needs to be improved.
3. Particleboard Particleboard is one of the environmental protection furniture boards. Particleboard is a thin board made of sawdust as the main raw material and then infiltrated with glue and additives. According to the pressing method, it can be divided into extruded particleboard and flat particleboard. The main advantage of this kind of plate is that it is extremely cheap. Its disadvantage is also obvious: its strength is extremely poor. Generally, it is not suitable for making large or mechanical furniture.
4. Fireproof board Fireproof board is one of the environmental protection furniture boards. Fireproof board is a decorative board made of siliceous or calcareous materials as the main raw materials, mixed with a certain proportion of fiber materials, lightweight aggregate, adhesive and chemical additives, and autoclaved. It is a new material that is used more and more, and its use is not only because of fire prevention. Fire-proof board construction requires higher glue, and the price of fire-proof board with better quality is more expensive than decorative board. Generally, the thickness of fire protection board is 0.8 mm, 1 mm and 1.2 mm. ..
5. Wood-plastic board Wood-plastic board is one of the environmentally friendly furniture boards. Wood-plastic board is a high-tech product produced by advanced technology and equipment. The tensile strength, flexural strength, flexural modulus, impact strength and Vicat softening temperature of its products all meet or exceed the international advanced standards. Wood-plastic products have the advantages of non-toxicity, corrosion resistance, moisture resistance, sound insulation, weather resistance and aging resistance. They can be sawed, planed, nailed, drilled and riveted like wood, and can replace the decoration materials polluted by toxic gases in the market.
Ok, that's all the green material xiaobian knows for you. I hope you can read Xiaobian carefully to make up for your lack of knowledge in this field. No matter which industry is introducing green materials now, it will definitely be welcomed when it goes on the market in the future, which is also a major trend of social development, so we should buy environmental protection materials when purchasing product materials.
