The use of dry ice for cleaning in the field of ship hull cleaning: Dry ice cleaning is better than water flushing for removing seaweed, underwater sludge, and shellfish. High-pressure water cleaning can only clean 80% and organic matter may reattach after cleaning. Dry ice cleaning of ships includes ship hulls, seawater intakes, seawater condensers, heat exchangers, computer rooms, machinery, and electrical equipment.

Application in the field of mechanical manufacturing: Dry ice machines are used in various types of production equipment, electrical equipment, hydraulic presses, pumps, and other machinery in the mechanical manufacturing industry. During the entire production process, these equipment are prone to accumulating metal dust, oil, and suspended solids, which can form a thick layer of dirt on the surfaces over time. It can be difficult to remove, but dry ice cleaning can effectively solve this problem.

Special precautions for using dry ice: Always be careful and use thick gloves or other protective materials when handling dry ice! Prolonged direct contact with the skin can cause frostbite and serious injury similar to mild or severe burns. Dry ice should not be used in cars, cabins, etc., as the sublimated CO2 can replace oxygen and cause breathing difficulties or even suffocation!

Do not allow children to handle dry ice alone!

Dry ice is extremely cold, do not put it in your mouth to prevent frostbite!

Use thick gloves, tongs, or other protective materials to handle dry ice (plastic gloves do not provide insulation!)

Ensure good ventilation when using dry ice and avoid using it in enclosed spaces!

Dry ice should not be mixed with liquids.

Shanghai Dishijie Dry Ice provides the following reminders: Use dry ice properly and safely to prevent any harm.

Symptoms and treatment of frostbite: Treatment for frostbite:

Do not rub, warm, or puncture blisters from frostbite to prevent infection.

Move to a warm place and keep the affected area in warm, dry air. Remove any constricting items to prevent swelling in case it becomes impossible to remove them.

Soak the affected area in gradually warmed water (37.0-40.0 degrees Celsius) for insulation.

Do not expose the affected area to cold again. Elevate the affected area to alleviate pain and swelling, then wrap it with a clean bandage and seek immediate medical attention at a large hospital for further treatment. The purpose of first aid is to restore the frozen fluids. Therefore, if the surrounding area of the affected part can be warmed quickly, it can be cured soon. Do not immediately immerse the affected area in hot water or use fire to heat it, as it may worsen the frostbite. Remember not to massage the affected area as it can cause further damage.
