Description
[technical field]
The present invention relates to ceramic coating technical field, specifically, is a kind of ceramic coating for track vehicle compartment and coating method thereof.
[background technology]
Urban track traffic (Rail Transit) has that freight volume is large, speed is fast, safety, on schedule, the feature such as protection of the environment, save energy and land used.Countries in the world are generally recognized: the fundamental solution that solves the traffic problems in city is to first develop take track traffic as key urban public tranlport system.
In CNS < < urban public transport major terms term > >, urban track traffic is defined as and " conventionally take electric energy as power, take the general name of the quick large conveying quantity public transport of wheel track drive manner.”
According to Chinese city track traffic association statistics, the year ends 2013, China's accumulative total has 19 cities to build up to put into operation 87 of city gauge lines, 2539 kilometers of operation mileages.Actual newly-increased 2 Operating cities in 2013,16 operating lines, 395 kilometers of operation mileages.In 2539 kilometers of operation mileages, 2074 kilometers, subway, accounts for 81.7% of total kilometrage; 192 kilometers of light rails, account for 7.6% of total kilometrage; 75 kilometers of single tracks, account for 3.0% of total kilometrage; 100 kilometers of modern tramways, account for 3.9% of total kilometrage; 30 kilometers of magnetic floating traffics, account for 1.2% of total kilometrage; 67 kilometers, the fast rail of administrative region of a city, accounts for 2.6% of total kilometrage.
Urban track traffic, owing to adopting electrical haulage, is compared and is not produced exhaust emission with motorbus.Due to the development of urban track traffic, can also reduce the quantity of motorbus, further reduced the exhaust emission of automobile.Owing to having adopted various noise reduction measures on circuit and vehicle, generally can not produce serious sound pollution to urban environment.
At present, the security of track traffic is more and more paid attention to, especially the problem of fire line.And inorganic ceramic paint is because it has the characteristic of health environment-friendly, particularly there is flame retardant properties and at high temperature without the excellent properties such as release of toxic gas, on subway carriage, started in recent years application.
