Dust filter bag cages surface treatment

1. Surface galvanized treatment : choose galvanized, which can prevent rust and oxidation, is cheap, and has a thin coating. Due to strict environmental protection requirements, galvanizing has gradually been replaced by galvanized wire treatment.

2. Pure epoxy resin powder coating: choose pure epoxy resin powder coating. It is resistant to acid and alkali, but it is expensive and has poor temperature resistance. It is not suitable for long-term use in high temperature environment. After spraying and shaking, the coating is prone to aging and cracking. The cracked edges and corners will wear out the bag. Not suitable for high temperature environments.

3. Coating with silicone: use solvent-based silicone coating, and use the method of immersion to attach the silicone layer, which is resistant to acid, alkali and temperature.

4. The surface of the stainless steel filter bag cage does not need any post-treatment and can better adapt to harsh working conditions, but the price is several times higher than that of silicone post-treatment.
