G-13 Corrosion Mitigation Protocol for Coastal... | terminalfaults.org

Technical Background:

Coastal environments introduce high concentrations of salt and moisture, accelerating electrochemical corrosion. This process degrades metallic components and PCB traces, increasing resistance and signal attenuation. Galvanic corrosion can occur between dissimilar metals in contact. High humidity lowers surface insulation resistance, leading to short circuits and erratic behaviour. Chloride ions penetrate protective coatings, facilitating corrosion under film.

Symptoms:

Observed corrosion on external surfaces of the G-13 card terminal. Potential functional impairments include card read errors, display malfunctions, and communication failures.

Possible Causes:

Saltwater spray deposition on exposed surfaces.
High humidity accelerating galvanic corrosion.
Electrochemical reactions between dissimilar metals.
Chloride ion penetration of protective coatings.
Failure of conformal coatings on printed circuit boards.
Degradation of cable connections due to oxidation.

Solution:

1

Disconnect the G-13 from its power source and network connection following safe handling procedures.
2

Visually inspect all external surfaces for signs of corrosion, paying close attention to connectors and seams.
3

Clean external surfaces with a non-abrasive, lint-free cloth lightly dampened with isopropyl alcohol (99% purity).
4

Apply a corrosion inhibitor specifically designed for electronic equipment to exposed metal surfaces, following manufacturer's instructions.
5

Inspect and clean cable connectors with a contact cleaner, ensuring proper mating and secure connections.
6

Relocate the kiosk to a less exposed location, if feasible, or install a protective enclosure.
7

Monitor the G-13's performance after treatment, noting any recurring issues.

Safety Warning:

Exercise caution when handling electronic equipment. Ensure the G-13 is disconnected from the power source before cleaning. Use appropriate personal protective equipment (PPE), such as gloves and eye protection, when handling cleaning agents and corrosion inhibitors. Ensure adequate ventilation when using cleaning solvents. Avoid spraying liquids directly into connectors or openings. Safe Handling procedures must be followed at all times.

Prevention:

Regularly inspect and clean the G-13's external surfaces with a non-abrasive cloth.,Apply a corrosion inhibitor to exposed metal surfaces every three months.,Ensure proper ventilation around the kiosk to minimize humidity buildup.,Use cable glands and weather-resistant connectors to protect cable connections.,Consider a protective enclosure to shield the kiosk from direct saltwater spray.,Implement a scheduled maintenance program to address potential corrosion issues proactively.

Expert Tip:

Apply a thin film of dielectric grease to cable connectors to prevent moisture ingress and corrosion. Consider using a desiccant pack inside the kiosk enclosure to absorb excess moisture. Ensure the desiccant is replaced regularly per manufacturer specifications.

Frequently Asked Questions

•What type of corrosion inhibitor is recommended for the G-13?

A corrosion inhibitor specifically formulated for electronic equipment, compatible with plastics and metals used in the G-13's construction, and compliant with relevant environmental regulations is recommended.

•How often should the G-13 be cleaned in a coastal environment?

Cleaning frequency depends on the severity of the environment, but a minimum of once per month is recommended. More frequent cleaning may be necessary in areas with heavy saltwater spray.

•What are the signs of irreversible corrosion damage?

Irreversible damage includes deep pitting, flaking of metal surfaces, and complete disintegration of components. Severely corroded components should be replaced, not repaired.
