As everyone knows, the air contains a lot of dust (such as dust, dust, dust, dust, sand and dust, powder particles, etc.) because of the dust particles is very light weight, so when the air flow in the dust particles, dust particles will offset the weight of itself, so that the dust in a floating state. Only in a relatively closed space, the air is relatively static, dust in the earth's gravity effect will fall to the ground, which is why the room doors and windows closed when no one residence, after a period of time and you will see the house with a thick layer of dust. The amount of dust in the air is related to many objective factors, such as weather conditions, seasonal changes, industrial production, mineral exploitation, land desertification, soil erosion and environmental pollution. Dust affects the human body, the production, the quality of the product, the environment, the beauty of the natural scenery and the ecological balance.
An adult needs about 19m3 air a day to get the oxygen needed. If the workers in the workplace air contains a lot of dust, dust amount of work in this environment is sucked into the lungs, a lot of harmful gases, liquids or some metal elements can be adsorbed thereon, with the breath of people and was brought into the deepest parts of the lungs or glued to the tube wall of the bronchus, cause or aggravate respiratory organ a variety of diseases, when reaches a certain quantity, can cause lung tissue fibrosis, the lung tissue gradually hardening, loss of normal respiratory function, lead to related diseases, so why in the environment with bad air index masks can prevent the disease effectively, because a mask is filter cotton, it can effectively filter out the dust particles in the air, so as to ensure the air cleanliness.
The dust in the air falls on the rotating parts of the machine, which will speed up the wear of the rotating parts and reduce the precision and life of the machine. Dust diffuse in the workshop, can also reduce visibility, affect the field of vision, prevent operation, reduce labor productivity, and even cause accidents. The dust discharged into the atmosphere will cause air pollution. In addition, the dust in the air will also reduce the visibility of the atmosphere, causing the formation of smoke and the transmission of solar radiation.
In summary, the filter has its indispensable status, because many industrial production must be carried out in a relatively clean space, such as surface treatment, paint coating, spraying, precision electronics, optical electronics, bio pharmaceutical, food production, air cooling, the environment requires the flow of air, but not dust, so you need to filter out dust with filtering cotton, just let the clean air to circulate in a relatively closed space, so as to achieve the needs of production and operation.
