Dry ice cleaning, as an environmentally friendly and efficient cleaning technology, has been widely used in the surface maintenance of high-speed train units in recent years. The surfaces of high-speed train units are prone to accumulate dirt, oil stains, and other pollutants, and traditional cleaning methods are often ineffective and may potentially damage the train’s exterior. Therefore, dry ice cleaning has emerged as an ideal cleaning method and has become the preferred choice for maintaining the surfaces of high-speed train units.

Dry ice cleaning utilizes the high-speed impact force and thermal differential effect of solid carbon dioxide (dry ice) particles to thoroughly remove oil, dust, and other dirt from the train’s exterior surface without the need for water or chemical cleaning agents. This cleaning method does not cause any damage to the train’s exterior and efficiently removes dirt, enhancing the appearance and maintenance of high-speed trains. Additionally, dry ice particles rapidly evaporate during the cleaning process, preventing secondary pollution and aligning with environmental protection standards.

In the surface maintenance of high-speed train units, dry ice cleaning offers several notable advantages:

Thorough and efficient: Dry ice cleaning swiftly removes dirt and oil stains from the train’s exterior surface, providing effective and rapid cleaning over large areas in a short period.

Environmentally friendly and non-hazardous: Dry ice cleaning does not involve the use of chemical cleaning agents, nor does it generate wastewater or secondary pollution, meeting environmental standards and posing no health hazards.

Preservation of the train’s exterior: Dry ice particles evaporate upon impact with the train’s surface, ensuring no damage to the train’s exterior, including the protective coatings and decorative elements.

Enhanced work efficiency: As dry ice cleaning does not require water or subsequent drying processes, it significantly improves maintenance work efficiency and eliminates the tedious steps associated with traditional cleaning methods.

Overall, dry ice cleaning has demonstrated numerous advantages as an advanced surface cleaning technology for high-speed train units’ maintenance. Its efficient and environmentally friendly approach, coupled with its non-damaging properties, makes it an ideal choice for maintaining the surfaces of high-speed train units, and it is expected to see broader applications in the future.
