What is particleboard?

The National Standards of the People's Republic of China proposed by the Ministry of Forestry of the People's Republic of China refer to the international IS0820-1975 "Definition and Classification of Particleboard", which defines the particleboard as follows:

Particle board Particle board

Particleboard is a sheet of pressed wood material made of wood or non-wood plants with or without a compound or excipient.

Generally speaking, particleboard (also known as "solid wood particle board") is a piece of wood and other raw materials that are cut into certain specifications, dried, mixed with adhesive, hardener, water repellent, and pressed at a certain temperature. Artificial boards.

As a kind of artificial board, is the particle board good? The author collected some comments about particleboard:

NO.1 particle board, sandwich board is the most common level of board, high-density board is a high-grade board, of course, MDF is used for furniture.

Is the plate of the NO.2 plate furniture good for medium-density boards?

——It should be better for MDF, less glue, better environmental protection, and more expensive.

NO.3 panel furniture, MDF particle board or particle board? It was fainted, and everyone said that it was good to sell.

——If you use indoors, I suggest you use medium and high density fiberboard because it emits less formaldehyde than particleboard. If it is used outdoors, my personal opinion is not to use particleboard because it is not as water resistant as medium and high density fiberboard. . But if you must use particleboard, it is recommended to be painted.

NO.4 What kind of plate is used for custom-made wardrobe? (MDF, particleboard) from the perspective of environmental protection, strength.

——The so-called particle board is the combination of the sawdust surface and the glue. It is the worst environmental protection standard. How can it meet the environmental protection standards? The formaldehyde content is very scary. There are mothers at home. Or children, such as the elderly, do not use particle board.

Moreover, the particle board has a poor nail holding force, and as long as it is moved, it is easy to be smashed in the future, and the quality and service life are limited. High-density boards are relatively better, and the price is more expensive than particle board.

NO.5 The standard of judging whether the board is good or bad

——1. Whether the board of the wardrobe is made of high-density board or particle board, the judging method is that the fine fibers in the high-density board are tightly combined, and the density is large and heavy. The high-density board can withstand a long service life; while the fine particle structure of the particle board is not tight enough, even small pores can be seen, it is lighter in the hand, the gravity is small, and the service life is short.

......

Speeches and information such as these are not listed here.

Is the particle board really so bad? Is the most common grade of sheet, the environmental standards are the worst, the amount of formaldehyde emission is amazing, the nail holding power is poor, and the moisture resistance is poor?

In the face of these negative and negative speeches, I can't help but ask, particle board, what mistakes have you made?

As we all know, a big difference between particleboard and MDF (medium density board) is that the internal structure of the particleboard is granular, and the MDF is powdery. Imagine, granular and powdery, adding glue to it. Which is more? To stick a bunch of powder, there is no doubt that the MDF contains more glue and the particle board is relatively less. Therefore, those who say that the MDF is environmentally friendly than the particle board, Absolutely wrong. Which kind of board is more environmentally friendly, this kind of formulation itself is not correct, whether it is particleboard or MDF, as long as your production technology is in compliance with the national environmental standards, then you are environmentally friendly.

As for the nail holding force, if the nail holding power of the particle board is poor, the nail holding force of the MDF is even worse. A nail is nailed into the MDF. Since the MDF is originally powdery, there is almost no gap in the middle. Therefore, the nail must be nailed in, and only part of the powder can be squeezed out to have space; the particle board is granular, in the middle. The gap is large, the nails are nailed in and there is room for it, and it will fit tightly with the board.

When it comes to moisture resistance, people who know a little about it know that the main material for cabinets is particleboard. why? Because the particle board has good moisture resistance. If a medium-density board is immersed in water, its powdery structure will quickly absorb water and swell like bread; while the particle board will be immersed in water, the particle board will be expanded to a certain extent and will not expand.

Inferior particleboard is really bad, but any plate has high quality and inferior quality. It is unfair to buckle the hats of “not environmentally friendly, not durable, and not moisture-proof” on all the particleboards just because of inferior particleboard. . In the previous article, the use of particleboard or MDF in the wardrobe as a criterion for judging the quality of the wardrobe sheet can be said to be arrogant and ignorant.

The production and use of particleboard is one of the main ways to save and efficiently use wood resources. It has positive and important significance for improving the comprehensive utilization of forest resources, alleviating the increasingly tight supply and demand of timber resources and protecting the ecological environment. In countries with developed wood-based panels around the world, the production of particleboard is much higher than that of fiberboard, but in China it is the opposite.

I hope that people's misunderstanding of particleboard can be eliminated as soon as possible. There is nothing wrong with particleboard. The fault is the person who destroys the image of the particle board and damages the reputation of the particleboard.
