Do good boards love "health preservation"? The secret to no cracking and no deformation is here

After using panel furniture for a long time, people found that the panel parts were deformed and cracked. This is related to its craftsmanship, design, and glue. But the root cause is that the panels have not been well "maintained".

What? The board also needs to be “healthy”?

That’s right! From a tree to a board, it needs to go through at least three “health preservation” processes!

First health care

Raw material stage

When the external temperature and humidity conditions change, wood will absorb moisture from the outside or release moisture to reach a new moisture balance with the outside world. Therefore, it is necessary to dry it to adapt to the atmospheric conditions of the use environment to minimize cracking and deformation caused by temperature and humidity changes in the use environment .

This process is the curing of wood before it is processed into boards. It usually takes more than 20 days. The specific duration depends on factors such as tree species, thickness, and craftsmanship.

Second health care

Gluing process

During the wood processing process, after gluing the front and back of the wood core, the board must first be cured for 12-24 hours. This curing time varies depending on climate conditions. The next step can only be carried out after the adhesive has initially cured to a non-sticky consistency . This prevents glue from escaping during cold pressing, which could lead to a weak bond. This is why, despite rigorously following all the previous and subsequent steps, boards can still debond. It's this "curing" step that's causing the problem.

The third health care

Puttying process

To ensure a uniform and smooth surface, all rough boards require varying degrees of "leveling," also known as "puttying. " The "putty" is primarily composed of powder and glue, which contains a certain amount of moisture, which can easily seep into the board, causing the moisture content to fluctuate again. Therefore, a 7-15 day "curing" period is required to promote the curing of the putty and balance internal stresses . The specific duration of this curing period depends on the moisture content of the board.

The health-preserving environment is particular

The health-preserving environment is also critical. It must be ventilated, dry, and kept at room temperature, avoiding external factors such as sunlight and rain. At the same time, boards cannot be stacked and must be separated to ensure that each board can get sufficient "health".

The ultimate goal of health preservation

First

Health care can further balance the internal moisture content of the board. The moisture content of the upper and lower parts, inside and outside of the board is different. Proper health care can make its internal moisture content tend to be consistent.

second

Curing can release the internal stress of the board. Changes in moisture cause changes in the size and volume of the board in all directions, which causes internal stress in the board. Proper curing can effectively reduce internal stress, thereby reducing deformation and warping.

Therefore, in order to avoid deformation, warping, degumming, cracking, etc. of boards or finished furniture , a "health maintenance" process is essential.

Proper health care

Ensure the board from the root, no deformation, no warping, no debonding, and no cracking.
