Now many people do not do their homework before buying cabinets, which leads to many people's conceptual misunderstandings. In order to prevent everyone from learning a lesson after mistakes appear, we can understand the correct situation. In this small series, we will list four misunderstandings about cabinet plates in advance, and friends who are ready to buy cabinets should read them carefully.

Myth 1: Are moistureproof and waterproof the same property?

In many people's minds, moistureproof and waterproof can be equated. In fact, this concept is also inaccurate. Moisture-proof function is to mix moisture-proof agent into the board substrate, and the moisture-proof agent is colorless. In order to distinguish it from ordinary plates, manufacturers add green or red colors (mostly green, more advanced red) as identification marks. The moisture-proof agent has no effect on the waterproof performance of the board itself. Practice has proved that the board with moisture-proof agent and the board without moisture-proof agent have the same expansion rate when immersed in water. The so-called moisture-proof only has an effect on the moisture in the air. Moistureproof agents are rarely used abroad because they pay more attention to surface treatment and tightness of edge sealing. Shanjia reminds you here, don't blindly believe in the performance of moisture-proof board, adding too much will affect the strength of wood-based panel.

Myth 2: Fire boards are fire-proof?

Xiaobian dispels doubts: Literally, this board is fireproof, and many consumers also have this misunderstanding. In fact, this name is incorrect. Refractory materials do not have real fire prevention. The correct name should be "fire-resistant board". The so-called "fireproof board" was introduced from Taiwan Province. As long as melamine is attached to the surface of any substance, it will have certain fire resistance, such as melamine once-formed board. There is a time requirement for fire-resistant board to resist open flame, which can only resist open flame barbecue for a period of time, and then it will produce a chemical reaction that is carbonized. The so-called "fire-proof board" can resist the open flame for about 35-40 seconds. In this range, the open flame barbecue can only produce black soot that can be wiped off, and there is no chemical reaction. Of course, the longer the fire-resistant board lasts, the better.

Myth 3: only look at the appearance to distinguish plates?

Quality depends on the material. The reason why the cabinets produced by small factories are cheap is that besides the processing means, the most important thing is the plate and cost. The surface of inferior board has a trainspotter, color difference, and it feels uneven. The surface of melamine veneer is brittle, and it is easy to fall off after being subjected to external force. From the cross section, the fiber particles of sawdust are uneven in thickness, with large gaps, and there may even be garbage such as dirt, nails and stones. In order to reduce the cost, many workshop-style small factories use a lot of inferior urea-formaldehyde glue, which has no cleaning link. Its performance can't be compared with the physical and chemical properties of high-quality particleboard. It looks similar in appearance, but its internal quality is very different.

Myth 4: There is little difference between domestic formaldehyde standards and foreign ones.

The European testing standard is 9mg, and the domestic regulation of formaldehyde in wood-based panels is: 9mg/100g dry panels, that is, 9 mg of free formaldehyde is allowed in 100 dry panels. The surface seems strict, which is not much different from that in foreign countries, but at the same time, there is another national standard, the allowable formaldehyde content of wood-based panels is 30mg after surface treatment, which is very protective for small production enterprises. When you buy cabinets, the indication of formaldehyde release can never be ignored.
