500W Airport Runway Rubber Laser Cleaning Machine

Laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece, so that particles, rust and coatings on the surface are evaporated and peeled off instantaneously, so as to achieve a clean process.

Description

For an airport, the runway is a key facility for its operations. When aircraft tires touch the runway surface at high speeds, high temperature is caused by friction. The high temperature makes the rubber melt formed by the instantaneous melting of the tire rubber and adheres to the texture of the road surface. As the number of friction increases and the passage of time, the road surface The continuous thickening of the rubber layer causes the friction coefficient of the road surface to decrease, which affects the braking performance of the aircraft. Especially when the road surface is wet, 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 must clean the runways from time to time every year, and ensure that the surface friction coefficient of the road surface is not less than 0.5, so as to avoid accidents.

At present, the commonly used degumming equipment in the industry includes

Ground milling machines and mobile shot blasting machines.

1. Glue removal by the ground milling machine will cause damage to the surface of the runway;

2. When removing glue from the mobile shot blasting machine, steel shots may be scattered on the runway. If it is not cleaned up 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, moving speed, etc. should be used according to the actual thickness of the "glue black", so as to achieve better cleaning efficiency and effects.

3. ZJ-CM500-LC hand-held cleaning machine is professionally customized for airport runway degumming. It can not only effectively remove the tire rubber layer on the runway, but also will not cause any damage to the airport runway. It is energy-saving and environmentally friendly. It is the first choice for cleaning the runway. equipment. The runway friction value after de-glue has been tested to fully meet the specified standards, which improves the quality of the runway surface and ensures the normal take-off and landing of flights.

Cleaning experiment

In order to test the practical application effect of laser cleaning on airport runway rubber, we used Raycus 500W pulsed fiber laser for experiments.

This laser has a wavelength of 1064nm, a pulse width of 130-160ns, a repetition frequency of 20-50kHz, and a laser core diameter. It is 200, and the single pulse energy is 25mJ. In the experiment, a cleaning speed of 20mm/s was selected, and the rubber was cleaned under each energy condition by direct radiation, and the experiment was finally successful.
