How can you not know these before buying the boards!

Eco-friendly paint-free boards are a highly sought-after material. They are recyclable, waterproof, anti-corrosion, and insect-resistant, and their ease of use and maintenance make them particularly popular with young consumers. In just a few years, they have become a new favorite in the board market. To adapt to the market, research and development have been conducted based on existing eco-friendly boards, leading to a wide variety of eco-friendly boards. For example, 360° formaldehyde-removing eco-friendly boards absorb and remove formaldehyde, making them a lifesaver for children's rooms.

Eco-friendly paint-free boards have two obvious advantages:

1. Practicality: The surface of the ecological paint-free board has no color difference, natural texture, fine texture, uniform structure, exquisite shape, and good wear resistance, washability, corrosion resistance and acid and alkali resistance. It is a good material for making furniture.

2. Environmental protection: Eco-friendly paint-free boards do not require paint, thus avoiding the pollution of indoor air caused by paint.

Even such an excellent board has some shortcomings. For example, eco-board is very easy to crack during cutting and edge sealing. Therefore, you must pay more attention during construction and avoid bumps and bumps, otherwise it is easy to damage the paint-free board. Once the paint-free board is damaged, it is permanent damage and difficult to repair. And everyone should also pay special attention: although eco-board is moisture-proof and waterproof, it will deform if it is exposed to moisture for a long time in a humid environment, such as in a humid bathroom.

But when encountering these problems, we must also know some professional knowledge of the panels.

1. The deformation and debonding of the board are caused by factors such as moisture content, bonding strength, impregnation and peeling;

2. The fracture of the plate is caused by the transverse static bending strength.

Analysis of factors affecting the moisture content of boards

1. Low solid content of adhesive

2. The hot pressing time is short, the hot pressing temperature is low, and the exhaust is not timely after hot pressing.

3. The moisture content of raw materials is too high

Analysis of factors affecting the bonding strength of boards

1. The moisture content of raw materials (veneer) is too high

2. The quality of the veneer is poor, the veneer material is different, or the pH value of the veneer is alkaline

3. The glue is too thin, too little or unevenly applied, or the flour quality is poor when mixing the glue.

4. Aging time is too long or too short

5. The hot pressing temperature is low, the time is short, the pressure is insufficient or the pressure reduction process is unreasonable

6. Blank spots in glue coating, contamination of single board and debris

Reasons affecting the impregnation and peeling of the board

1. The glue quality is poor, the viscosity is insufficient, and the glue coating is uneven.

2. The flatness of the substrate material is poor (such as fir and Malacca core).

3. The board surface is not scraped cleanly and the surface coating material is thick.

4. During hot pressing, the temperature is low or the time is short, the glue cannot be fully cured, resulting in poor bonding quality. The long cycle before hot pressing causes the glue to be pre-cured in advance.

Analysis of the causes affecting the transverse static bending strength

1. The eucalyptus or poplar core board is too thin, and the upper and lower strengths are maintained by the tension of the core board.

2. The core board is thick enough but the sanding is uneven, and there is no tension in the heavily sanded areas.

3. The hot pressing pressure is not enough.

4. The width-to-thickness ratio of the board core does not meet the standard requirements, and the quality of the board core is poor, such as the flatness of the fir or Malacca core (there are high and low differences) or the wood fiber is loose.

5. The glue quality is poor and the coating is uneven.

After reading this, do you feel that there is so much knowledge about board materials? We only need to understand these professional knowledge. For consumers, we still hope to buy satisfactory products. Therefore, the editor recommends that you choose big brands and purchase board products through formal channels.
