Dust removal bags are an important component of dust collectors, and their performance and service life directly affect the dust removal effect. However, in some cases, dust removal bags may corrode, which not only affects their service life but may also have a negative impact on the dust removal effect. Let’s take a look together.
The corrosion reasons of dust removal cloth bags
Chemical corrosion: Some chemical substances react with the material of the dust removal bag, causing chemical corrosion of the bag. For example, strong acids, strong bases, and other chemical substances may cause damage to the fiber structure of cloth bags, causing them to lose their original strength and filtration performance.
High temperature oxidation: In high-temperature environments, dust removal bags may undergo high-temperature oxidation reactions, leading to changes in fiber structure and decreased performance. After prolonged exposure to high temperatures, the color of the cloth bag may change, and even embrittlement, cracking, and other phenomena may occur.
Microbial corrosion: Some microorganisms grow and reproduce on the surface of the cloth bag, producing acidic substances and enzymes, causing damage to the fiber structure of the cloth bag. This type of microbial corrosion typically occurs in damp, poorly ventilated environments.
Mechanical wear: During the operation of the dust collector, the impact and friction of dust particles on the surface of the bag may cause mechanical wear of the bag. After prolonged operation, the cloth bag may experience wear and tear.
Moisture influence: Moisture is another important factor that causes corrosion of dust removal bags. Excessive humidity may cause the cloth bag to absorb moisture, deform, and even breed microorganisms. In addition, moisture may also cause electrochemical corrosion, accelerating the process of bag damage.
