When choosing high-quality wallpaper, it's important to evaluate it from several key aspects. Here’s how you can identify the quality and safety of a product:
1. Material Identification: First, determine whether the material is natural or synthetic (such as PVC). A simple way to test this is by burning a small piece. Natural materials typically burn without a strong odor and produce white, powdery ash. In contrast, synthetic materials like PVC emit a distinct chemical smell, create black smoke, and leave behind black, globular residue when burned.
2. Water Resistance Test: High-quality wallpaper should have good color fastness. You can test this by gently rubbing the surface with a damp cloth or water. If the color remains intact and doesn’t fade, it's a sign of better quality.
3. Odor Check: A safe and eco-friendly wallpaper should be odorless. When purchasing, bring the product close to your nose and check for any strong chemical smells. Unpleasant odors may indicate the presence of harmful substances such as toluene or ethylbenzene, which can be potentially carcinogenic over time.
4. Light Fastness: The coating and pigments used in wallpaper should be of high quality to prevent fading or yellowing, especially under prolonged exposure to sunlight. This is particularly important for light-colored or white wallpapers, which are more prone to discoloration.
5. Design and Craftsmanship: Look for unique patterns and excellent production processes. A well-made wallpaper will have a consistent texture, sharp printing, and no visible imperfections. This not only enhances the aesthetic appeal but also ensures durability over time.
