Board Encyclopedia-How to Choose High-Quality Paint-Free Board

Wood panels are the most widely used material in the current building materials market. However, the use of adhesives in their production process releases a certain amount of free formaldehyde, and paint-free panels are no exception. Because of this, paint-free panels require extremely high production process requirements. Although many paint-free panels on the wholesale market are advertised as E1 or even E0 grade, misjudgment is inevitable. As a consumer, today, Wood Panel Network will teach you how to choose paint-free panels.

1. Choose paint-free boards with excellent appearance:

1. Flatness test method: In a dimly lit place, look at the board surface at a 45-degree angle to see if there are any unevenness, and see if the three joints and sanding marks on the surface are obvious. For example, if the surface of a fir board is uneven, feel it with your hand to see if it is uneven. If so, it means that the factory has poor control capabilities.

2. Check whether the paper fades. Relatively speaking, ink paper is less likely to fade and has a stronger three-dimensional effect, while pigmented paper is less so.

3. Check whether there is carbonization on the surface. For example, if there is fog or shiny spots on the surface, or if it turns black over time or the paint on the surface fades, these are all dry and wet spots. These reflect the factory's mastery of technology and are also one of the important issues reflecting the quality of the board.

2. Choose environmentally friendly paint-free boards:

The environmental protection level of paint-free boards can generally reach E1 level. The E0 level paint-free board process is more difficult to achieve, but E1 paint-free boards are more meaningful than E0 blockboards, because the traditional process still requires glue to stick decorative boards and paint.

Environmental testing method: After the finished cabinet is closed for a period of time, open it again to see if there is any odor or irritation to the nose and eyes.

3. Choose paint-free boards with good structure:

1. Testing method: Stack two boards, stagger them, and expose them to the sun for a few hours. Then check if there is any color difference on the lower board. Cracking and bubbling on the board are caused by the bonding strength and base material. There is no reason to doubt that there is a quality problem. You can see it with your eyes.

Check to see if the paper is completely fixed. You'll notice the surface isn't resistant to stains, and it won't feel smooth or cottony to the touch. The board may appear foggy. The best quality is one that feels like metal.

2. Testing method: Apply shoe polish, red lipstick or oil pen on the board surface for a few minutes to see if it can be completely wiped off.

Check if the decorative paper is firmly attached to the wood. (This is related to woodworking; sawing can cause edge flaking, increasing processing difficulty and affecting aesthetics.) To test: Use strong glue to adhere to a small area per square decimeter and pull hard to see if the paper comes off. Alternatively, use your hand to pry the paper off the cross-section to see if the topmost piece of paper can be removed.
