Surface treatment of medium efficiency filters

Many filters accumulate oxides, hydroxides, lubricants, anti-rust oils, release agents, dust, and other contamination layers on the surface during use, which can prevent the adhesive from wetting the adhered surface and therefore require appropriate treatment.

In the medium efficiency filter, many products are made of metal frames such as galvanized sheets, stainless steel sheets, aluminum alloy, aluminum plate, etc.
These metal frames will absorb a certain amount of moisture and dust if they are exposed to the air, so proper treatment can ensure that the surface is free of dust, moisture, and oil.


In addition to increasing the adhesion of the equipment components, surface cleaning also reduces the cost of gluing.
If you want to reduce the cost of use, it is important to take a holistic approach and consider the choice of various materials to ensure the quality of the product and at the same time reduce costs.
And the appropriate surface treatment is undoubtedly an important method to remove the dust, oil, rust, residue, oxidation, wax, welding spots, solvents, moisture, and other substances on the surface to be glued, and the main treatment methods are divided into the following kinds of:

1、Surface cleaning.

2、Degreasing to remove oil.

3、Rust removal and roughening.

4、Cleaning and drying.

5、Chemical treatment.

6、Protection treatment.

In general, the use of the last two methods in the process of surface treatment of medium efficiency filters is relatively small, but we can also combine one, two, or several of these methods to achieve different results.
