Blockboard is a kind of man-made board with beautiful surface, environmental protection and convenient construction. The main part in the middle is spliced with wooden squares, which has the functions of scratch resistance and wear resistance. Because melamine resin adhesive is used in the production of blockboard, it is also called melamine board. Blockboard does not need to be painted, so it is also called paint-free board. The following article introduces in detail what materials blockboard is and its advantages and disadvantages?
What is blockboard?
Blockboard is a kind of solid wood ecological board. Ecological board is a new type of green and environmentally friendly material, with solid wood as the main material. At the same time, its surface is processed and made of density board or foam board.
Blockboard has obvious characteristics, such as stability, and it also has very good moisture resistance and can prevent color fading. After being made into furniture, it does not need to be painted again, which can meet the requirements of environmental protection. Because it does not contain formaldehyde, it truly brings people a green and healthy home life.
Surface material of blockboard
The decorative board made by soaking paper with different colors or textures in resin, drying it to a certain degree of solidification, laying it on the surface of joinery, and hot pressing it is standardly named melamine blockboard. Calling it melamine blockboard actually refers to part of its finishing component.
Blockboard surface composition
- The surface paper is placed on the top layer of the decorative board to protect the decorative paper, making the surface of the board after heating and pressurization highly transparent, hard and wear-resistant. This paper requires good water absorption, white and clean, and transparent after dipping.
- Decorative paper, that is, wood grain paper, is an important component of the decorative board. It has a base color or no base color. Decorative paper printed into various patterns is placed under the surface paper. It mainly plays a decorative role. This layer requires the paper to have good hiding power, impregnation and printing performance.
- Covering paper, also called titanium white paper, is generally placed under the decorative paper when manufacturing light-colored decorative boards to prevent the bottom phenolic resin from penetrating the surface. Its main function is to cover the color spots on the surface of the substrate. Therefore, it is required to have good covering power. The above three types of paper are respectively impregnated with melamine resin.
- Bottom paper is the base material of the decorative board. It plays a role in the mechanical properties of the board. It is impregnated with phenolic resin glue and dried. During production, several layers can be determined according to the purpose or thickness of the decorative blockboard.
Advantages of blockboard
Blockboard overcomes the problem that paint boards are prone to scratches or have a strong odor. The material selection is more particular, it is not easy to have blistering problems, and the moisture resistance is also very good.
Blockboard has many colors and types, and the colors are more gorgeous. At the same time, because blockboard has not been painted or sprayed, it is relatively low-carbon and environmentally friendly, and has many excellent functions that wood does not have. Using it to make furniture can form a protective film on the surface, so it is more slip-resistant and wear-resistant. Don’t worry about dripping some acidic and alkaline substances on it, it has acid and alkali resistance.
Disadvantages of blockboard
- Blockboard is easy to be damaged when cutting, so its production process is relatively complicated, and it is a new type of board, so the production process has not been perfected.
- Because blockboard has many advantages, it is very popular in the market, but it is also sold as inferior by many manufacturers. Be careful when buying to avoid buying low-quality products.
The above is the introduction of the classification, uses and raw material processes of blockboard in this article. I hope it can help you!
