According to its function can be divided into room temperature dust bag, anti-static dust bag, easy to dust dust bag, anti-oil waterproof dust bag, dust film cover, dust removal bag can be divided into two types: Bags and so on. General dust bag small diameter, high strength, good ventilation, strong ability to absorb ash, acid corrosion, can withstand high filtration load, with dust collection efficiency, dimensional stability and other characteristics. Mainly used for metallurgy, iron and steel chemical industry, food building materials, petroleum, food processing, wood and other industries workshop dust dust treatment projects.

Dust: Dust refers to suspended solids in the air. There are many names of dust, such as dust, dust, smoke, dust, dust, powder, etc., these terms there is no clear boundaries. International Organization for Standardization, particle size less than 75μm solid suspension is defined as dust. The existence of dust in the atmosphere is one of the main reasons to keep the temperature of the earth, too much or too little dust in the atmosphere will have a disastrous impact on the environment. But in life and work, the production of dust is a natural enemy of human health, is the main cause of a variety of diseases.

Dust hazards: pollution of the atmosphere, endangering human health. Elegant dust in the atmosphere often contains many toxic ingredients, such as chromium, manganese, cadmium, lead, mercury, arsenic and so on. When the human body inhalation of dust, less than 5μm particles, easily in-depth lungs, causing toxic pneumonia or silicosis, and sometimes can cause lung cancer. Once the pollutants deposited in the lungs are dissolved, it will directly invade the blood, causing blood poisoning, not dissolved contaminants, may also be absorbed by the cells, leading to cell structure damage. In addition, the dust will stain the building, so that valuable ancient buildings subjected to corrosion. Dust falling on the foliage of a plant hinders photosynthesis and inhibits its growth.
