Description
Technical field
The present invention relates to runway cleaning except glue technical field, in particular to a kind of ice pellets and utilize ice pellets to carry out the method and apparatus of airfield runway except glue.
Background technology
Runway " glue is black " mainly aircraft landing time gear tyre and the black belt shape material that produces of runway severe friction.It is with the increase of aircraft landing number of times, airfield runway is due to aircraft takeoffs and landings, aero tyre and ground surface high speed high temperature friction, the rubber produced melts, adhering on (race) face, road makes rubber be bonded at runway surface, and constantly thicken, formed in the touch-down zone at runway two ends large-area " black mark ", reduce runway coefficient of friction simultaneously.After time grown, it is very smooth that coarse face, road will become, and easy making is overrun like this.If it is above standard, value is accumulated to certain thickness when effectively not clearing up, and will land and bring hidden danger, will cause aircraft accident time serious, and can cause fatal crass what is more to aircraft safety.On November 30th, 2004, Indonesia one frame passenger plane to be flown off the runway after-explosion in Henry David Thoreau landing at the airport, causes 106 people's injures and deaths 47 people missing.On September 16th, 2007, Phuket, THA International airport one airplane was flown off the runway with the building hard hit of near airports and blast on fire, led to 88 people and to die tragedy.Main cause be all airfield runway cleaning not in time, glue is seriously black, and it is out of control when causing aircraft landing to slide that runway coefficient of friction is not up to standard.Therefore, each large airport all will be cleaned runway every year aperiodically, and guarantees that face swimming cloths coefficient μ is not less than 0.42, so just can avoid the generation of accident.
Current airfield runway removes gluing method and mainly utilizes the method such as high pressure water washing, road surface shot-blasting machine Shot Blasting.But runway of the prior art removes glue technology has following shortcoming:
High pressure water cleaning method, the too huge energy consumption of cleaning equipment is high, and due to rubber and pitch be all the close organic matter of composition, runway rubber is black is that the condition of high temperature is got off the plane the fusions of rubber for tire and runway pitch, the impulsive force of high-pressure water jet is limited is difficult to effective separation, and inside some cleaning agents containing toluene etc. to environment and the large organic matter of harm, after cleaning, environment is worked the mischief.
Road surface shot blasting method, although the shot used or sand ball have stronger hitting power, easily damages runway surface, causes flatness to destroy.And tiny shot or sand ball are difficult to reclaim completely, what have also can remain on runway, causes potential safety hazard.
Therefore, runway removes the present urgent problem of glue to be had: solve water jet hitting power deficiency and be difficult to effectively be separated glue is black, solve except glue process causes secondary injury to runway, avoids foreign matter to remain, solve cleaning fluid composition to environment and harm.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of ice pellets and utilize this ice pellets to carry out method and device thereof that runway removes glue, be difficult to effectively separation and removing and chemical residual to problems such as environments to solve runway except " glue is black " in glue process.
