Before buying cabinets, many consumers did not do their homework, leading to misunderstandings in many concepts. In order to prevent the situation from being correctly recognized after the lessons have been learned, Xiao Bian hereby lists the misunderstandings of the four large cabinet plates in advance, and the friends who are ready to buy the cabinets should pay attention. Misunderstanding 1: Is moisture and waterproof a property? In many people's minds, moisture and water resistance can be equated. In fact, this concept is also inaccurate. The moisture-proof effect is to incorporate a moisture-proofing agent into the sheet substrate, and the moisture-proofing agent is colorless. In order to distinguish it from ordinary plates, manufacturers add green or red colors (mostly green and more advanced red) as identification marks. The moisture-proofing agent does not have any influence on the waterproof performance of the board itself. Practice has proved that a plate with a moisture-proof agent and a plate without a moisture-proof agent are immersed in water, and the expansion ratio is the same. The so-called moisture-proof is only effective for moisture in the air. Moisture-proofing agents are rarely used abroad because they pay more attention to the rigor of surface treatment and edge sealing. Here, Shan Jia reminds you not to blindly believe in the performance of the moisture barrier. Adding too much will affect the strength of the wood-based panel. Myth 2: Fire boards are fireproof? Xiaobian explained: From the literal point of view, this board is fireproof, and many consumers also have this misunderstanding. In fact, this name is not correct. There is no real fire prevention in refractory materials. The correct name should be “refractory boardâ€. The so-called "fireproof board" is called from Taiwan. Any substance that has a surface-attached melamine will have certain fire resistance properties, such as a mono-hydrogenamine primary forming plate. For refractory boards, there is a time requirement for resistance to open flames. It can only be grilled for a period of time after being exposed to an open flame, and then it will be charred by chemical reaction. The so-called "fireproof board" can withstand fires of about 35-40 seconds. Within this range, open flame barbecues can only produce black soot that can be wiped off without chemical reaction. Of course, the longer the fire resistance time of the refractory board, the better. Misunderstanding 3: Just look at the appearance of the sheet? Quality depends on the material. The reason why the cabinets produced by small factories are cheap, except for processing methods, the most important ones are plates and costs. The surface of inferior sheet has a translucent bottom, color difference, and it is uneven, and the surface of the melamine surface is brittle. After being subjected to external force, it is easy to fall off. From the cross section, the fiber particles of wood chips are not uniform, the gap is large, and there may even be dirt and nails. And rubbish such as stones. In order to reduce costs, many workshop-style small factories use a large amount of inferior urea-formaldehyde glue, which has no cleaning process, and its performance is incomparable with the physical and chemical properties of high-quality particleboard. It looks similar in appearance and the inner quality is very different. Misunderstanding 4: Domestic formaldehyde standards and foreign countries are not much different? About the standard of testing European standards is 9mg, China's regulations on artificial board formaldehyde: 9mg/100g dry board, that is, 100 mg of free formaldehyde is allowed in 100 dry boards, the surface is stricter, and the difference is not big, but at the same time the country still There is another standard. After the surface treatment of the wood-based panel, the formaldehyde content is allowed to be 30 mg. This standard is very protective for small-scale manufacturers. When you buy a cabinet, the amount of formaldehyde released can be an important indicator.
