What are the anti-corrosion measures for power fittings?

The anti-corrosion measures for power fittings mainly include the following methods, which are aimed at improving the corrosion resistance of fittings and ensuring the stable operation of the power system:

Chemical cleaning method:

Principle: Use acid and alkali solution for cleaning to remove rust and corrosion on the surface of fittings.

Features: Fast speed and good cleaning effect, but the ratio and temperature of the cleaning solution are high, and safety should be paid attention to when using.

Mechanical grinding method:

Principle: Use mechanical equipment to grind and remove rust and corrosion on the surface of fittings.

Features: The process is simple, but if the grinding force is not enough or the treatment is not thorough, secondary rust and other problems are likely to occur.

Spray treatment method:

Principle: Spray special coating on the surface of fittings to form a protective film to prevent metal corrosion again.

Features: Easy operation, environmental protection, good anti-corrosion performance, it is an ideal anti-corrosion method for fittings.

Anti-corrosion paint brushing method:

Principle: Use anti-rust paint suitable for metal surface for brushing, which can not only remove rust, but also prevent secondary corrosion.

Features: The difficulty lies in the uniform thickness of the brushing layer, and the metal surface needs to be treated before brushing.

Multi-layer coating method (combined with reference articles 1, 2, and 4):

Steps:

Remove the dirt on the surface of the power accessory, and then evenly apply a layer of paint to increase the toughness and flexibility of the surface of the power accessory.

Apply a layer of epoxy resin on the joint and lay a layer of glass cloth before the epoxy resin cures.

Then apply two layers of epoxy resin on the surface of the glass cloth, and after the two layers of epoxy resin are cured, apply three layers of epoxy resin and lay two layers of glass cloth.

Subsequently, four layers of epoxy resin are applied to the two layers of glass cloth, and one or more layers of epoxy resin are applied to the fourth layer of epoxy resin.

Features: The anti-corrosion power accessories manufactured by this method have the advantages of corrosion resistance, good insulation performance, good mechanical bearing capacity, and good flexibility.

Epoxy resin and glass cloth combination method:

Principle: Apply epoxy resin layer by layer and lay glass cloth on metal accessories. Through the curing effect of epoxy resin, the glass cloth is tightly bonded to the surface of the hardware to form a solid anti-corrosion layer.

Features: This method combines the anti-corrosion properties of epoxy resin and the mechanical strength of glass cloth, and can effectively resist external corrosion and mechanical damage.
