Why is the wooden door deformed? How to prevent the deformation of the wooden door?
What are the reasons for the deformation of the wooden door?
Moisture : The high moisture content of wood is also another major cause of deformation of the wooden door. With the decrease of the moisture content during use, the internal stress of the wood will gradually be revealed, eventually leading to deformation and cracking.
Design structure : whether the wooden door design structure is reasonable (including internal); whether the actual production is made according to the process requirements; whether the adhesive is fully cured; whether the transportation and placement meets the requirements; the environmental status of the use place is also an important reason for the deformation of the wooden door. .
Material issues : Whether it is a solid wood door or a solid wood composite door, there are wood components, and wood, like other objects, has the characteristics of shrinking and swelling, wood logs are natural, and the degree of deformation is specified more seriously than synthetic materials. In addition, the wooden door has a large area and a small number of fixed points, so it is the most likely to cause deformation and cracking.
Moisture content : The moisture content of wood is high. During use, the water gradually decreases, and the internal stress of the wood is slowly exposed, leading to deformation and cracking.
Growth factors : Natural wood has various factors in the growth process, resulting in uneven wood density. When the wood is shaved, the balance of internal stress is changed and the wood is deformed and cracked.
Quality problems : The deformation of solid wood doors is sometimes a certain quality problem. Improper construction can also cause deformation. For example, improper drying, shallow back slots, and insufficient expansion gaps during construction can cause wooden door deformation.
How to prevent the deformation of the wooden door?
Keeping the indoor ventilation well allows the wooden door to be at normal room temperature and humidity to prevent the wooden product from being deformed due to moisture and excessive temperature difference, corrosion of metal fittings, edge sealing, and loss of decorative materials.
When using electric heating or other heating equipment during the winter season, keep away from wooden products so as not to deform them by heat.
Wooden door paint is afraid of bumping, so pay attention to the impact protection. In terms of cleaning, organic solvents cannot be used for scrubbing. Organic solvents can damage the surface of the paint.
When painting the wall, the wooden door should be covered to avoid the paint falling on the surface of the product, which will peel off and fade the decorative material and affect the overall appearance.
The hinges and locks are movable parts. When they are loose, they should be tightened immediately. The sound of the hinge position should be timely filled with oil. When the lock is open, it is inflexible to add the appropriate amount of pencil core to the key hole. Do not accidentally fill the oil.

Carburetant
Using the carburetant can make the most of the scrap steel and reduce using the pig iron. The content of carbon is very high. Its color is black.When the carburant is used in casting, the consumption of scrap steel can be greatly increased, and the consumption of pig iron can be reduced or pig iron is not needed. At present, most of the carburant is suitable for electric furnace smelting, and a small part of the carburant with particularly fast absorption speed is used for cupola. Charging method of electric furnace smelting, should be the carburant with waste steel and other materials into the casting, small dosage can choose to add on the surface of molten iron. But to avoid mass feeding into molten iron, in order to prevent excessive oxidation and carbon effect is not obvious and casting carbon content is not enough. The addition amount of the carburizing agent is determined according to the proportion of other raw materials and the carbon content. Different types of cast iron, according to the need to choose different types of carburant. The characteristics of carburant itself choose pure carbonaceous graphitizing substances, reduce excessive impurities in pig iron, the selection of carburant can reduce casting production costs.
