The characteristics required for mining air duct cloth are as follows: firstly, it should be durable and sturdy, with strict regulations for gas filtration, and it should also be moisture and electricity resistant. The function of the air duct is comprehensive. If there are unique regulations that allow for easy disassembly and installation, are not likely to cause harm to the natural environment, are wear-resistant, not afraid of high and ultra-low temperatures, and exceed health and safety standards, then it is considered a qualified ventilation duct. People need to professionally select certain unique materials for their air ducts based on their specific needs. For example, if they are exposed to outdoor environments for a long time, they must choose a material with stronger corrosion and rust resistance. If they are in a room, people can choose some more cost-effective materials. People also need to choose different types of air ducts based on their different purposes and functions. When choosing, everyone should be cautious. Secondly, in future applications, people should pay attention to good safety protection to prevent certain low or high temperature irritants and avoid cracking during thermal expansion and contraction. Perhaps quarterly electroplating process spraying is also beneficial for increasing the service life of ventilation ducts.
Pay attention to the following matters when repairing:
1. The surface of the air duct must be cleaned and tidy, without leaving any smoke or dust, especially when there is a lot of coal dust in the mine, it must be cleaned and tidy.
2. The surface of the air duct must not have any moisture. Because resin adhesive belongs to the category of strong adhesive for evaporation, the surface of the air duct is humid, and the more harmful it is to evaporation in mining, the less effective the bonding effect is in practice.
3. When repairing, strong adhesive must be applied to both the air duct surface and the repair material surface, and bonding should be carried out when the surface does not return to light.
4. In areas with standards, the bonding surface can be heated up to ensure sufficient bonding between the resin adhesive and the surface layer of the fabric.
Due to the relatively polluted and oxygen deficient underground gas, as well as excessive smoke and dust, the windproof cylinder cloth used in mining must have natural ventilation and be closely connected to the air duct. There must be equipment to dilute harmful gases and smoke in the liquid gas. Mining ventilation ducts are usually durable and suitable for use in wells. When carrying out work, there will be a lot of smoke and dust caused. Therefore, it is necessary to have a smoke and dust filtration system for the air duct cloth, so as to transport fresh gas to the underground workers and ensure their safe and satisfactory work.
