What are the mistakes that experts have to say about the hidden products of sheet products?

Consumers often ignore many issues when buying sheet products. Many of these problems are mistakenly believed to be normal, but in reality, such misconceptions can lead to the purchase of low-quality materials. Currently, the market for board products is quite chaotic, and there are hidden dangers that consumers may not easily detect. So, how can you spot these traps? Let’s take a look at what experts have to say about the common pitfalls in board products. **Misunderstanding 1: Moisture-proof and Water-resistant Are the Same** Many people think that moisture-proof and water-resistant are interchangeable terms. However, this is not accurate. Moisture-proofing involves adding a moisture-resistant agent into the board’s core, which is usually colorless and does not mix with water. It's important for consumers to understand the difference between these two properties when purchasing, so they don’t fall into the marketing traps set by some sellers. **Misunderstanding 2: Fireproof Board Is Actually Not Fireproof** At first glance, the term "fireproof board" suggests it is completely fire-resistant. In reality, the correct term should be “refractory board.” These boards are not truly fireproof, but they do have some fire resistance. For example, HPL (High-Pressure Laminate) boards can withstand flames for up to 35–40 seconds. During this time, they may produce black smoke but no chemical reaction occurs. The longer the fire resistance time, the better the product tends to be. **Misunderstanding 3: You Can Judge Quality by Appearance Alone** Some people believe that poor-quality boards can be identified just by looking at the surface. However, this is not always true. Inferior sheets may show signs like uneven color, translucent backing, or a brittle melamine layer that can easily flake off. If you check the cross-section, you might find uneven wood fiber particles, large gaps, or even impurities like nails, stones, or debris. When choosing a board, start by checking the surface — a smooth and even finish is a good sign. Then, inspect the internal structure to verify its authenticity. **Misunderstanding 4: Zero Formaldehyde Means No Formaldehyde at All** You may have heard of "zero formaldehyde" boards on the market. But do these really mean no formaldehyde? Experts clarify that this is more of a marketing tactic than an actual feature. There is no truly zero-formaldehyde product available today. Consumers should be cautious and do their research before making a purchase. When buying sheet products, it's easy to fall into certain misunderstandings. Without proper knowledge, it can be challenging to choose healthy, eco-friendly, and safe brand products. Being informed can help you avoid these common mistakes and make smarter choices.
