The air duct is used to ventilate various buildings, commonly known as ventilation duct. The material used to make this pipe can be metal or not. But its role is to make air flow through the pipes, and it can also reduce the amount of harmful substances in the air. The materials used by it must meet the relevant national standards. Inspections must be performed when purchasing materials, and only those that meet national standards can be used.
There are many materials for making ducts , most of them are steel, some are stainless steel, plastic can be used, and white iron can be used. In addition, materials that can be used for ventilation ducts include thermal insulation cloth. There are many uses for it. Some are used in central air-conditioning, some are used in factories, and some are used in mines. It can discharge harmful gases in mines. There are also several shapes for duct processing, most of which are round and square. It is used in a wide range of daily life. If there is no dust in the electronics production workshop, this kind of pipe can filter the air. In the factory that produces drugs, there is no bacteria when it needs to be produced. This product can also help Eliminate bacteria.
In some industrial production, harmful substances are emitted to pollute the environment. It can help remove dust and smog, thereby making production workers more comfortable in their work and life. If it is used in central air conditioners, insulation boards can be used, and FRP can also be used. Most of the ventilation ducts used in the exhaust device of the factory are steel plates. If FRP is used, care must be taken to ensure that the material does not catch fire and meet fire standards. Ventilation ducts are carefully designed before construction.
