Bag filter, as a daily filter equipment commonly used, is favored by users. Although it is a machine and equipment, there will be corrosion, especially its shell. Only by understanding what causes it can we make the right medicine. So, bag filter shell corrosion phenomenon is why?
1. Poor performance of the materials used
The anticorrosive paint is suitable for the inner wall anticorrosive treatment of different steel water tanks, oil storage tanks and water pipelines. Their hardness is relatively low, and the performance of chemical solvent resistance is relatively good, but its adhesion and impact resistance strength is not enough, and it is not suitable for the use of sewage treatment equipment with high production requirements.
2. The drying time is not enough
After brushing the anticorrosive layer, we should keep the ventilation time sufficient and the drying time ≥12h, which can reduce the occurrence of such problems.
3. The coating thickness is not enough
If the corrosion intensity of the treatment cutoff is relatively high, the low thickness of the anticorrosive layer should reach 0.15-0.2mm, and many manufacturers reduce the thickness to 0.1mm in order to save costs, which can not meet the low requirements of the design industry specification, which directly affects the anticorrosive effect.
4. Improper surface treatment
In the process of producing air filter, if the workers do not do a good job of rust removal, can not meet the requirements, the bonding force of primer and top paint is relatively poor and the adhesion is not enough, it will directly affect the anti-corrosion effect.
5. the construction is not standard
In the process of construction do not pay attention to the protection of the anti-corrosion layer, a lot of steel materials will scratch the inner anti-corrosion layer, and when filling the filter material, if you do not pay attention to light handling, and the particle size, high hardness of pebbles directly into the bottom of the bag filter will destroy the inner anti-corrosion layer.
The above is the bag filter shell corrosion phenomenon is a simple description of why, if you have other want to know can consult Henan Aite environmental protection Equipment Co., LTD. The company is focused on R & D, production and manufacture of replacement imported filter element, filter, oil filter and other oil purification products, sewage treatment products, air dust removal products, pure water treatment products, filter press products.
