Topic：Lumber and Small-Scale Decay Folding and Causes of Prevention and Control
Introduction
Structural timber and tiny-scale dropped during construction of properties, which can lead to significant losses and safety hazards. There is a need to prevent deformations and folding of lumber and small-scale materials during construction. These problems are caused by many factors such as inadequate timber production, storage, and use. This article will discuss the causes of lumber and small-scale decay folding, and then describe the prevention and control measures.
Causes of Lumber and Small-Scale Decay Folding
The main causes of lumber and small-scale decay folding can be divided into three categories: external factors, endogenous factors, and material inadequacies.
External Factors
The external factors are mainly the environmental conditions such as humidity, temperature and light. For example, if the humidity of a room is too high, the wood will absorb excessive moisture and become brittle. Furthermore, extreme temperatures can cause wood to shrink, distort, or even crack. In addition, direct sunlight can cause accelerated deterioration of wood.
Endogenous Factors
Furthermore, the endogenous factors that cause lumber and small-scale decay folding include the construction process, the timber production process, and the poor quality of wood. Wrong structural design makes wood more vulnerable to folding, and using wood that is not suited for the environment can also cause folding. In addition, an inferior production process can lead to poor quality of wood and make it prone to folding.
Material Inadequacies
Lastly, the material inadequacies that lead to lumber and small-scale decay folding include the wrong selection of materials, the deficiency of preservative chemicals, and the lack of quality control in production and installation. Wrong selection of materials means that the material chosen is not appropriate to the environment and building load, hence affecting the quality and service life of the lumber; insufficient preservatives unable to confine the deformation and reduce the susceptibility of the materials to folding; lack of strict quality control in production and installation, especially installation in an environment with complex environmental conditions.
Prevention and Control Measures
In order to prevent lumber and small-scale decay folding, it is important to take some preventive measures to control the external and endogenous factors, as well as material inadequacies.
Control External Factors
The external factors causing lumber and small-scale decay folding can be controlled by properly adjusting the environmental conditions, for example, keeping the humidity below 45%, and controlling the temperature between 15℃ and 25℃. Moreover, the natural light in affected locations can be reduced by using blinds or curtains.
Control Endogenous Factors
When constructing a building, it is important to select the appropriate building materials, and adopt structurally secure designs. Moreover, the timber production process should be strictly monitored, and the quality of wood should be verified.
Control Material Inadequacies
First, the materials used should be selected based on the load and environmental factors, and their quality should be tested before installation. Then, preservative chemicals can be applied to the timber to reduce susceptibility to folding. Finally, when installing structural lumber, appropriate equipment and installation techniques should be used and quality control should be monitored.
Conclusion
Lumber and small-scale decay folding during construction of buildings can cause economic losses and safety issues. To prevent and control lumber and small-scale decay folding, it is important to properly control the environmental conditions, select appropriate building materials, use correct processes and techniques, as well as apply preservative chemicals to the timber. By following these measures, it is possible to effectively minimize the occurrence of lumber and small-scale decay folding.
