Wood doors often encounter problems with door leaf deformation during production, processing and use. How to effectively avoid the deformation of wooden doors is a topic that everyone cares about. Today Tianda Wooden Door will share with you some secrets and avoidance measures for the deformation of wooden doors.
The wooden door is connected to the door frame by the hinge (or hinge) on the left or right side of the door leaf during use, and the rest is in a free state. The reason for the deformation of the wooden door is the stress imbalance on both sides of the door leaf.
Taking the center of the thickness of the door leaf as the reference, when the stress on both sides of the door leaf is equal, the door leaf is in a straight state; when the stress on both sides of the door leaf is different, the stress balance is broken, and the bending deformation occurs;
This stress imbalance is the result of a combination of factors, both the cause of the wooden door itself and the external environment. The factors that cause the deformation of the wooden door leaf are mainly the structure of the product, the materials used, the processing technology of the wooden door, the storage, installation and use environment of the wooden door.
Analysis of the causes of wooden door deformation
1. The product structure is asymmetrical and deformed.
That is, the material properties of the two sides of the door leaf should be inconsistent. Due to the different thickness of the facing material, the distance between the rubber layer on both sides of the door leaf and the center line of the door leaf is inconsistent. Although the stress generated by the adhesive during the curing process is the same, the door leaf is bent and deformed due to the difference of the force arms. Some small-brand factories use good materials on the front and low-cost materials on the back, so they are particularly prone to deformation.
Requirements: In the production process of wooden doors, the thickness, type and structure of the facing materials must be the same.
2, improper selection of materials to cause deformation
As we all know, wood is a kind of dry shrinkage and swelling material. Within a certain water content range, with the change of the moisture content of the wood itself, the size and shape of the wood itself change. This phenomenon is called dry wood. It shrinks and swells, so this is also the case with wooden doors.
3. Unreasonable process technology causes deformation
For example, after the door leaf is covered with the finishing material, it cannot be immediately processed into the next process. On the one hand, the adhesive is not cured completely, and on the other hand, because the adhesive contains a large amount of moisture, which is not in the glued material. Spread evenly. For products processed by hot pressing, the temperature is much higher than the ambient temperature, and the subsequent processing is required after the product temperature and the ambient temperature are balanced. This balancing process is professionally called "Chen Hua". After hot pressing, it can be directly stacked and aged for aging. It can also be used as a drying machine to reduce the temperature of the door in a short period of time, to achieve a balance between the product and the ambient temperature, and to shorten the post-aging time.
Requirements: Wooden doors should strictly abide by the production process standards during the production process.
4, improper installation caused deformation
The technical quality of the wooden door installation also directly affects whether the deformation occurs in the use of the wooden door. If only two hinges are installed on the wooden door, the hinge will be heavily weighted and prone to deformation.
Requirement: When installing the wooden door, the verticality of the door frame and the door leaf must be ensured, so that the center of gravity of the door leaf is on the center line in the thickness direction of the door leaf, and the opening is flexible. In addition, each door should be installed with 3 hinges. The position of the hinge installation is 1/10 of the height of the door leaf from the upper and lower doors, and the middle 1 piece is centered on the upper side.
5, improper use caused deformation
The deformation of the wooden door has a close relationship with the environment in which it is located. In addition to the factors of the wooden door itself, the cause of the deformation of the wooden door also has environmental factors. Since the wood itself is easily affected by the surrounding environment, the wooden door made of wood material is easily deformed when the environmental conditions (mainly temperature and humidity) vary greatly.
Requirements: For places with harsh conditions, such as vents, where the wind is large and the wind is small, the environmental conditions inside and outside the wooden door should be avoided for a long time.
