Fiber bag duct is a common ventilation system material, which is composed of fiber cloth and metal wire mesh. Compared with traditional metal ducts, fiber bag ducts are lighter and softer, so they are widely used in construction, industry, aerospace and other fields.
However, like other materials, fiber bag ducts can be mechanically damaged. Major mechanical injuries include tearing, abrasion, and pressure damage.
First of all, the fiber bag duct is susceptible to tear damage. Due to the softness of the fiber material, the fiber bag duct is prone to tearing when subjected to large tensile or tearing forces. For example, during the construction process, if the construction personnel use too much force when installing the fiber bag air duct or the tool is not operated properly, it may cause the air duct to tear.
Secondly, the fiber bag duct is also susceptible to wear and tear damage. The wear is mainly caused by the friction between the fiber bag air duct and other objects during long-term use. For example, where ducts are bent or traversed through confined spaces, fiber bag ducts may come into contact with building structures or other equipment, causing wear and tear. Although fiber cloth bags usually have good wear resistance, long-term use will still cause some wear and tear.
Finally, fiber bag ducts are also susceptible to pressure damage. The skeleton of the fiber bag duct is usually composed of metal wire mesh, and the fiber bag mainly plays the role of protection and filtration. When large external pressure is applied, the fiber material of the fiber bag may not be able to withstand it, causing pressure damage. For example, when the air duct is squeezed by external force or the building structure is deformed, the fiber bag air duct may be squeezed and deformed or cracked.
To sum up, although the fiber bag duct has the advantages of being light and soft, it is also inevitably exposed to the risk of mechanical damage. In order to avoid the occurrence of damage, we can take the following preventive measures: first, pay attention to the operation during the construction process to avoid excessive force or improper tool operation;The second is to consider the rationality and safety of the structure when designing and installing the fiber bag air duct, and try to avoid the friction between the air duct and other objectsThe third is to regularly check the condition of the fiber bag air duct during use, and repair or replace the damaged part in timeThe fourth is to improve the wear resistance and pressure resistance of the fiber bag air duct and improve its mechanical properties.
