In the supply chain of ship manufacturing, maintenance and daily operation, Marine waterproof connectors as a key component to ensure the stable operation of the electrical system, the integrity of its quality and performance is crucial, even in the storage stage that has not yet been installed, the slightest mistake may also "no use first loss". The correct storage method ensures that these connectors remain in top condition when put into service, ensuring the safe navigation of the ship. As a manufacturer specializing in the production of various waterproof connectors, I will introduce how waterproof connectors should be stored.

Humidity: Moisture is key

Marine waterproof connectors are mostly made of metal and rubber and other materials, and humidity is the enemy of these materials. High humidity environment is easy to rust metal parts corrosion, rubber sealing ring moisture may lose elasticity, thus affecting the waterproof performance of the connector.

In order to deal with the humidity problem, we must first choose the appropriate packaging materials. It is recommended to use plastic film or aluminum foil bag with high moisture resistance for independent packaging, these packaging materials can effectively block the intrusion of external moisture, and create a relatively dry small environment for the connector. In the package, you can also place an appropriate amount of desiccant, such as silica gel desiccant, which can absorb the trace water vapor remaining in the package to further reduce the humidity risk.

For the storage environment, the humidity is controlled at 40%-60%. If the warehouse is located in an area with high humidity, installing dehumidification equipment is essential. Common dehumidifiers can continuously remove water vapor from the air and maintain a dry state in the warehouse by condensing or absorbing/absorbing water. At the same time, to avoid placing the connector directly on the ground, shelves or trays should be used to prevent ground moisture penetration.

Temperature: Good for long

Temperature fluctuations also have a significant impact on Marine waterproof connectors . Extreme high temperatures may cause deformation of the plastic shell and accelerate the aging of the rubber, while low temperatures will make the material brittle and reduce its mechanical properties.

In general, the storage temperature of the connector should be controlled between -20℃ and 40℃. In the cold winter or hot summer, the warehouse needs to be equipped with the corresponding temperature control equipment. If in winter, heating equipment such as heating or electric heaters can be used to ensure that the warehouse temperature is not lower than the lower limit; In summer, the air conditioning refrigeration system is used to prevent excessive temperature.

In addition, the connector should not be exposed to direct sunlight for a long time, even in the packaging. Because the ultraviolet rays in the sun have strong energy, long-term exposure will make the plastic shell and rubber parts aging, fading, shorten their service life. When choosing a warehouse location, priority should be given to areas that are sheltered from light and well-ventilated.

Salt spray: Keep away from the source of corrosion

Given that Marine waterproof connectors are mainly used in the Marine environment, even in the onshore storage stage, it is necessary to prevent the erosion of salt spray. The sea air often contains a lot of salt, these salt particles attached to the surface of the connector, the water will form an electrolyte solution, accelerate the corrosion of metal parts.

The location of the warehouse should be as far away from the sea as possible, and the ideal distance is more than a few kilometers to reduce the impact of salt spray. If the conditions can not be far away, then the tightness of the warehouse is particularly important. Ensure that warehouse doors and Windows are closed and effective sealing strips are installed to prevent salt spray from being invaded by the wind.

In terms of packaging, in addition to moisture-proof function, it should also have a certain ability to prevent salt spray. Some special anti-rust paper or anti-rust film can form a protective film on the surface of the metal parts to prevent the salt from contacting the metal directly. For the connector that has been opened but is not used for the time being, it is necessary to repackage and take protective measures in time.

Review regularly: nip in the bud

Even in a good storage environment and packaging conditions, regular inspection of Marine waterproof connectors is an essential link. Through regular review, potential problems can be found in time and corresponding remedial measures can be taken.

A full review is recommended every 3-6 months. The contents of the check include: check whether the package is intact, if damaged, the package should be replaced in time; Check whether the appearance of the connector has signs of rust, discoloration, deformation, etc., paying special attention to the metal contact points and sealing rings; Use a simple tool to test the insertion and withdrawal force of the connector to ensure that the connection performance is still normal. If slight rust is found, rust remover can be used for treatment, and apply appropriate amount of anti-rust oil; For the case of aging or deformation of the sealing ring, the new sealing ring should be replaced in time.

The storage link of Marine waterproof connectors  is an important line of defense to ensure its quality and performance. Only through careful selection of packaging materials, strict control of the storage environment and regular careful inspection can we ensure that these connectors are intact before installation and use, laying a solid foundation for the stable and reliable operation of the ship's electrical system, so that the ship can sail safely and worry free on the vast ocean. Remember, details determine success or failure, and more attention to storage can reduce the risk in the voyage.
