There Are so Many Reasons for Wood Door Cracking. How to Choose and Prevent It?

Expanding on the topic of wooden door cracking and deformation, let us further delve into the reasons behind these issues, discuss the necessary knowledge before purchasing and installing wooden doors, and explore additional measures to avoid these problems.

Cracking of wooden doors can occur due to various factors. One common reason is inadequate or poor-quality glue used in the joints. Additionally, if the flatness of the door is below 80%, it can lead to cracks. The relative humidity of the connected parts should not exceed 2%, and the humidity of the solid wood should be below 12% to prevent cracking in the joints. Another cause of cracking is when the wood board itself is not properly dried before processing, leading to high moisture content in the core and dry surface. Fluctuations in temperature and humidity can then cause the moisture to evaporate, resulting in cracks.

Deformation of wooden doors is mainly caused by the moisture content within the wood. As the moisture content decreases over time, the internal stress of the wood gradually reveals itself, leading to deformation and eventually cracking. The design structure of the wooden door plays a significant role in its potential for deformation. It is important to ensure that the door is made according to proper production processes and that the adhesive used is fully cured. Transportation and placement must also meet the recommended guidelines. Moreover, the environmental conditions in which the door will be used can strongly impact its deformation.

When it comes to selecting wooden doors, there are several precautions to consider. It is crucial to choose products from reputable manufacturers who have extensive knowledge of the technical essentials in manufacturing wooden doors. They should have researched climate and environmental conditions, including high temperatures and humidity, to ensure that their doors perform well even in adverse conditions.

Another aspect to pay attention to is the thickness of the wooden door. Thinner handles are preferable as they reduce the chances of deformation. The recommended thickness for a wooden door is typically between 38mm to 45mm. This thickness provides stability and strengthens the door structure, making it less prone to deformation.

The material of the wooden door is also important. By knocking on the door, one can assess the quality of the wood. A good quality wooden door will produce a mellow sound with texture. Additionally, it is necessary to consider the paint process on the wooden door. A well-finished paint job will have a smooth and uniform luster and color. The strength and luster of the paint should be comparable to that of automobile metal paint.

While selecting a wooden door, it is essential to inquire whether it is made of solid wood or is a composite one. Understanding the principle of heat expansion and cold contraction is crucial. Wooden objects, including wooden doors, tend to expand with rising temperatures, and this expansion can lead to cracking. Being mindful of these factors can help consumers prevent cracking by adopting simple maintenance practices for their wooden doors.

In conclusion, the cracking and deformation of wooden doors can be attributed to factors such as inadequate glue, high moisture content, and improper design structure. To avoid these problems, it is crucial to select wooden doors from reputable manufacturers, pay attention to thickness and material quality, and consider the paint process. By understanding the principles of heat expansion and cold contraction, consumers can take the necessary precautions to maintain their wooden doors and prolong their lifespan.
