The following are some effective measures for rust prevention of pneumatic hoist:

1、 Surface pretreatment

Cleaning:

Before carrying out rust prevention treatment, the surface of the pneumatic hoist must be thoroughly cleaned to remove impurities such as oil, dust, and moisture.

Solvent cleaning, alkaline cleaning, or electrochemical cleaning methods can be used.

Rust removal:

If the surface of the pneumatic hoist has rusted, rust removal treatment is required.

Manual rust removal, mechanical rust removal, or chemical rust removal methods can be used.

2、 Coating protection

Primer:

Choose a suitable primer for coating to enhance the adhesion between the coating and the substrate.

The primer should have good anti rust and weather resistance properties.

Topcoat:

After the primer dries, apply the topcoat to provide additional rust protection and decorative effect.

The topcoat should have excellent corrosion resistance, weather resistance, and wear resistance.

Coating thickness:

Ensure that the thickness of the coating meets the specified standards to provide sufficient rust protection.

Thin coatings may result in poor rust prevention, while thick coatings may affect the performance of pneumatic hoists.

3、 Electrochemical protection

Cathodic protection:

For some critical components or areas prone to corrosion, cathodic protection technology can be used.

By applying external current, the metal surface becomes a cathode, thereby suppressing the occurrence of corrosion reactions.

Anode protection:

In some cases, anodic protection technology can also be used.

By turning the metal surface into an anode, a dense oxide film is formed to prevent further corrosion.

4、 Daily maintenance

Regular inspection:

Regularly inspect the pneumatic hoist to promptly identify and address potential corrosion issues.

The inspection includes checking whether the coating is intact, whether there are cracks, peeling, and other phenomena.

Keep dry:

Try to keep the pneumatic hoist in a dry environment to reduce the occurrence of corrosion.

When used in humid environments, dehumidification measures can be taken.

Avoid collision:

During use, avoid collisions between the pneumatic hoist and hard objects to prevent damage to the coating and corrosion.
