HANDLING & CLEANING GUIDELINES FOR COATED TANK CONTAINERS WITH PROCO-EMAIL, BLACK®
This ISO tank container is internally equipped with a high-performance coating: Proco-EMAIL, black®. In order to protect the coating from any damages, we strongly recommend following these handling and cleaning precautions.
- Avoid any impact on the inside and outside wall of the tank container.
- During cleaning work, refrain from impact and from the use of hard tools. Avoid any damage such as scratches and scores.
- Persons stepping on the tank container must wear slip-proof rubber shoes (smooth sole, without inclusions).
- Access ladders or any other equipment entering the tank container must be padded in order to protect the coating from mechanical damages.
- Porosity tests may only be performed with 90V, wet sponge method (e.g. Elcometer 270).
- The tank container must always be kept under a protective gas atmosphere as far as possible. Preferably clean and dry it after every use.
- As many chemical products decompose under the influence of moisture, they must be transported under a protective gas atmosphere.
- The coating absorbs the filling material to a small extent. Therefore, a reaction which may result in damage to the coating is possible during washing or in case of lengthy dwell times.
- Make sure to lift and transport the tank container with appropriate equipment.
- Completely empty the tank container (residual amount max. 10 litres).
- Completely fill up the tank container with cold water (100%).
- Completely empty the tank container again.
- Clean inside walls and fittings with clear water or soaps or detergent additives, or alkaline carbonate additives (sodium bicarbonate, max. 5%).
- Never use any alkali hydroxides such as sodium, potassium hydroxides or ammonia (NH4)!
- Do not use any detergent additives capable of mechanically damaging the coating surface.
- Rinse with warm water under pressure at < 50 bar and < 50°C.
- Post-wash the tank container with cold water.
- Empty the tank container again and dry it properly.
- Store the tank container under dry protective gas atmosphere.
