How to identify the quality of melamine board

When purchasing and using melamine sheets, you can conduct a comprehensive evaluation through appearance, physical properties, environmental protection level, odor and other aspects to ensure that the quality of the selected products meets the requirements and ensure its safety and durability in use.

The following are some of the main identification standards and methods

1. Appearance inspection

Surface flatness: The surface of high-quality melamine sheets should be smooth and flat, without obvious dents, bubbles, scratches or other defects.

Uniform color: The color should be uniform and consistent, and there should be no obvious color difference or stains.

Edge processing: Check whether the edges of the sheets are neat and have no burrs or gaps.

2. Size and thickness

Size measurement: Use tools such as vernier calipers to measure the length, width and thickness of the sheets to ensure that they are consistent with the nominal size.

Thickness uniformity: Measure the thickness at multiple locations to ensure that there is no obvious thickness difference.

3. Physical property test

Bending strength: The strength and toughness of the sheet can be perceived by simply bending the sheet manually. High-quality sheets are not easy to bend or break.

Abrasion resistance: Use tools such as sandpaper to test the wear resistance of the surface. The surface of high-quality sheets is not easy to be scratched.

Waterproofness: After soaking the surface of the board in water for a period of time, check whether it warps or deforms.

4. Environmental indicators

Formaldehyde emission: Test the formaldehyde emission through a professional testing agency to ensure that it does not exceed the national standard (such as E0, E1, and E2 levels).

Other harmful substances: Find out whether the product has been environmentally certified and check its relevant certificates.

5. Odor

Odor test: Smell the smell of the board. High-quality melamine boards should not have a pungent chemical smell. If there is a strong chemical smell, it may indicate that it contains excessive harmful substances.

6. Certification mark

Check the certificate: High-quality melamine boards usually have relevant quality certification marks, such as ISO certification, environmental certification, etc., to ensure that they meet industry standards.

7. Manufacturers

Choosing a reputable brand or manufacturer can usually get high-quality products with greater assurance.
