We need to be careful about the material of the chair, because if we sit for a long time, a bad chair will affect our spine. Chairs need to be designed according to different sitting postures to make people feel comfortable, so what is the material of the chair?

What material is this chair made of? 1 The chair is made of several materials:

There are many kinds of materials for making chairs, such as leather sofa chairs, made of leather and wooden frames; Solid wood chairs are mainly made of beech, teak, maple and other kinds of wood, which are natural and environmentally friendly; Steel chairs are polished, sprayed with zinc and other anti-corrosion treatments, which are affordable.

How to choose a suitable chair;

1, fixed demand:

The main function of a chair is to sit, but because everyone's body shape is different, his height and weight are also different, so we can't choose a chair just by appearance. To choose according to the family situation, it is best to choose a soft chair with a handle, so that sitting on your ass is not sore and your arms are not drooping.

2. Materials:

There are many kinds of materials for chairs, such as wood, bamboo and steel. But when choosing, they must first match the style of the table, neither too high nor too short. It is best to decide according to the decoration style and environment of the house.

For example, it is not recommended to choose a wooden chair in a humid environment. When choosing a chair in the office, we should consider its comfort and moderate hardness to avoid the damage to cervical and lumbar vertebrae caused by sedentary; The chair in the living room should be made of durable and soft materials, which makes it more comfortable to sit.

3. Choose a brand:

Finally, when choosing a chair, it is best to choose a brand product, because it is not only frequently used, but also an indispensable necessity. A good chair can not only guarantee the quality, but also highlight the quality of home.

What material is this chair made of? 2 1, gray.

Wood has great compressive strength, static bending strength and parallel tensile strength. Ash wood is mainly used to make luxury furniture, which is easy to be processed by tools, polished smoothly and corrosion-resistant. Wood has great compressive strength, static bending strength and parallel tensile strength.

The appearance of Fraxinus mandshurica is similar to that of Sophora japonica, and the heartwood varies from light brown to dark brown. The wood grain is obvious and rough. Uses: high-grade furniture, floors, decorative lines, fine woodworking products, sports equipment, tool handles, etc.

2. Oak

Solid material, fine texture, reddish brown color, used for furniture, farm tools, etc. It is produced in the provinces south of Qinling Mountains and Yangtze River. Korea and Japan are also distributed. Tussah is an evergreen shrub or small tree, a national second-class precious tree species, and also the main secondary forest tree species in Northeast China.

3. Birch

Birch is light brown to reddish brown with shiny surface and smooth mechanism. Yellow-white slightly brown, obvious annual rings, pure and thin wood, slightly hard, fine structure, high mechanical strength, elasticity, high hygroscopicity, easy to crack and warp when drying.

It is not very durable in perishable environment, and it is more used in the form of plywood. Birch is usually used in special plywood, flooring, furniture, pulp, interior decoration materials, vehicle and boat equipment, plywood and so on. The furniture made is smooth and wear-resistant, with clear patterns.

4. Elm

After drying, shaping, carving and polishing, elm can make exquisite lacquer carving crafts. Russian old elm (purple elm) is the most classic, with the advantages of clear texture and less scarring. It is a precious material for making furniture. The raw material price of elm per cubic meter is about 1.500 yuan. The wood grain is straight, the pattern is clear, the wood has good elasticity, moisture resistance and corrosion resistance.

5. Jujube

The heartwood of the old jujube tree can exceed 1.0 and sink. The wood grain is beautiful, hard, corrosion-resistant, wear-resistant and moth-proof, and its products are unique because of their golden ripples, especially suitable for high-end furniture and floors.

The wood is yellowish brown, but the central part of the old wood is reddish brown. This reddish brown is often used as the color of jujube because of its large proportion. However, this reddish-brown central part is not heartwood, and its difference from normal heartwood is uneven color tone and irregular distribution in vertical and horizontal sections.

What material is this chair made of? 3 1, solid wood board.

As the name implies, solid wood boards are made of complete wood. These plates are durable and natural in texture, making them the best choice for decoration. However, due to the high cost and high construction technology requirements, this kind of plate has not been widely used in decoration.

Solid wood boards are generally classified according to entity names, and there is no unified standard specification. At present, in addition to the floor and door leaves, we generally use artificially processed wood-based panels.

2, splint

Plywood, also known as plywood, is commonly known as thin core board in the industry. It is made of three or more layers of veneer or thin plate with a thickness of one millimeter by hot pressing. It is the most commonly used material for handmade furniture at present. Splints are generally divided into six specifications: 3 cm, 5 cm, 9 cm, 12 cm, 15 cm, 18 cm (1 cm is 1 mm).

3, decorative board decorative board, commonly known as panel.

It is a decorative board with one-sided decoration function, which is made by precisely planing solid wood plates into thin veneer with a thickness of about 0.2mm, using plywood as the base material and adopting the gluing process. It is a special way of splint, with a thickness of 3 cm.

4. Core plywood

Blockboard, commonly known as large core board. The large core board is formed by gluing and splicing two veneers in the middle. The price of large core board is cheaper than that of thin core board, and its longitudinal bending and compressive strength is poor, but its transverse bending and compressive strength is high.

5. Core plate

Particleboard is a thin board made of wood particles 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.

6, density board

Density board, also known as fiberboard. It is an artificial board made of wood fiber or other plant fiber and urea-formaldehyde resin or other suitable adhesive. According to its density, it is divided into high density board, medium density board and low density board.

High-density board is easy to reprocess because it is soft and impact-resistant. In foreign countries, MDF is a good material for making furniture. However, because the national standard for height board is several times lower than the international standard, the use quality of MDF in China needs to be improved.

7, fire board

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 type of material that is used more and more at present, 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. ..

8. melamine cardboard

Tri (poly) cyanamide board, the full name of which is tri (poly) cyanamide impregnated adhesive paper veneer artificial board, is a kind of wall decoration material. Its manufacturing process is to soak paper with different colors or textures in melamine resin glue, then dry it to a certain curing degree, then spread it on the surface of particleboard, medium density fiberboard or hard fiberboard, and then hot press it into decorative board.
