Laser Cleaning - Airport Runway Rubber Black Terminator

Laser cleaning technology refers to the process of using high-energy laser beam to irradiate the surface of the workpiece, so that the particles, rusts and coatings on the surface are instantaneously evaporated and peeled off, so as to achieve cleanliness.

When aircraft tires land at high speed, the high temperature is caused by friction contact with the runway surface. The high temperature causes the rubber melt formed by the instantaneous melting of the tire rubber to adhere to the pavement texture. With the increase of friction times and the passage of time, the pavement rubber layer is continuously thickened, resulting in a decrease in the friction coefficient of the pavement and affecting the braking performance of the aircraft. Especially in the wet state of the pavement, the viscosity of the rubber on the runway significantly reduces the friction force, which directly affects the safe landing of the aircraft.

Therefore, major airports have to clean the runway irregularly every year and ensure that the surface friction coefficient of the pavement is not less than 0.5, so as to avoid accidents.

At present, the commonly used degumming equipment in the industry includes ground milling machine and mobile shot blasting machine. However, the rubber removal of the ground milling machine will cause damage to the surface of the runway ; the mobile shot blasting machine may have steel balls scattered on the runway. If it is not cleaned in time, it will cause damage to the aircraft and increase the workload of workers.

In the actual cleaning operation of the runway, different energy and moving speed should be adopted according to the different thickness of the actual ' glue black ', so as to achieve better cleaning efficiency and effect.

Laser handheld cleaning machine

The laser hand-held cleaning machine is specially customized for airport runway cleaning. It can not only effectively remove the tire rubber layer on the aircraft runway, but also does not cause any damage to the airport runway. It is energy-saving and environmentally friendly. It is the preferred cleaning equipment for aircraft runway cleaning. The friction value of the runway after degumming has been tested to fully meet the prescribed standards, improve the quality of the runway surface, and ensure the normal take-off and landing of the flight.
