What Is Melamine Board And Chipboard?

Melamine

The whole name of the melamine plate is the artificial plate of melamine-impregnated glue paper. It is soaked in paper mine resin adhesives with different colors or textures and then dried to a certain degree of solidification. It is paved on particleboard, medium-density fiberboard or hard fiber plate surface, and the decorative plates are made by heat pressure. Essence During the production process, it is generally composed of several layers of paper. Generally composed of tablet paper, decorative paper, covered paper, and bottom paper.

1. The table layer paper is placed on the top layer of the decorative board to protect the effect of decorative paper, so that the surface of the board after heating is highly transparent, and the surface of the plate is hard and wear-resistant. transparent.

2. Decorative paper, that is, wood grain paper, is an important part of the decorative board. It has a background or no background. It is printed into a variety of patterns. The paper is required to have good covering, impregnation and printing performance.

3. Covering paper, also known as titanium white paper, is generally placed under the decorative paper when manufacturing light-colored decorative boards to prevent the underlying phenolic resin on the surface. The main function is to cover the color spots on the surface of the substrate. Therefore, it is required to have a good cover. The above three kinds of paper are immersed in melamine resin.

4. The underlying paper is the grass-roots material of the decorative board. It has a mechanical performance of the plate. It is made of phenolic resin glue and drying. Several layers can be determined according to the thickness of the use or decorative board during production.

Performance of Melamine Decorative Board

• You can imitate a variety of patterns at will. The color is clear. It is used as a variety of artificial boards and wood. It has high hardness, wear resistance, and good heat resistance.
• Good performance of chemical resistance can resist the abrasion of solvents such as general acid, alkali, oil and alcohol.
• The surface is smooth and clean, and it is easy to maintain and clean.
• Because it has the excellent performance that natural wood cannot have, it is often used in interior buildings and various furniture and cabinets.
• Sanjulamine plate is a wall decoration material. At present, some people use melamine boards to fake compound flooring for ground decoration, which is inappropriate.
• Common specifications: 2440mm × 1220mm, thickness 3-25mm.

In indoor decoration, it is often used to make light-body furniture, long service life, and rapid processing, and is not recommended as large-scale commercial display material.

The Advantages And Disadvantages Of Melamine Board

• The advantages: flat surface, because the double-sided expansion coefficient of the board is the same but not easy to deform, the color is bright, the surface is wear-resistant, corrosion-resistant, and the price is cheap and lower.
• Disadvantages: Globes are usually used when the melamine plate is made, and glue will be harmful to the human body, especially some unsightly glue; the sealing edge is easy to collapse, the glue marks are obvious, and the gong flowers can only be directly sealed.

Chipboard

What is particleboard? English name: particle board(PB), also known as particle board, bagasse board, made of wood or other lignocellulosic materials, the application of adhesive after heat and pressure glued into the wood-based board. Also known as scrap board. It is mainly used in the furniture and construction industry and the manufacture of train and automobile carriages.

1. Particle board according to product density: low density (0.25~0.45 g/cm 3), medium density (0.55~0.70 g/cm 3) and high density (0.75~1.3 g/cm 3)3, usually produce 0.65~0.75 g/cm 3 density, particle board.

2. According to the slab structure, it is divided into a single layer, three layers (including multi-layer) and a gradual structure.

3. According to water resistance, indoor water resistance and outdoor water resistance are divided. The arrangement of shavings in the slab has two kinds: directional type and random type.

4. In addition, there are non-wood materials such as cotton stalk, hemp stalk, bagasse, and rice husk made of particleboard, as well as inorganic adhesive materials made of cement wood wire board, cement particleboard, etc. Particleboard specifications are more, the thickness from 1.6 to 75 mm, 19 mm as the standard thickness, commonly used thickness of 13, 16, 19 mm 3.

5. As the basis for evaluating the quality of particleboard and the main performance considered when using, the physical properties include density, water content, water absorption, thickness expansion rate, etc. In terms of mechanical properties, there are static bending strength, vertical plate tensile strength (internal bonding strength), nail holding force, elastic modulus and rigid modulus. In terms of process properties, it has machinability, glueability, paint finishing, etc. For particleboard for special purposes, its electrical, acoustic, thermal and anti-corrosion, fire and flame retardant properties should be considered according to different uses. The production method of particleboard is divided into flat pressing method, extrusion method and roll pressing method according to its slab forming and hot pressing process equipment. Flat pressing method is intermittent production, extrusion method and roll pressing method are continuous production. In actual production, the flat pressing method is the main method.

6. Particleboard is a thin sheet made of wood fragments as the main raw material and then permeated with glue and additives. According to the pressing method, it can be divided into extruded particleboard and flat particleboard.

The Advantages And Disadvantages Of Chipboard

• The Advantages: The particleboard structure is more uniform, with good processing performance. It can be mass-produced and is a better raw material for making different specifications and styles of furniture.

• Cons: The cost is low, but the strength is not very large, it is easy to crack, and a large amount of adhesive is added when pressing, which contains some substances harmful to the human body.
