Description
Technical field
The invention belongs to railway transportation and antifreeze snow-clearing technique field, be specifically related to a kind of anti-freeze fluid being applied to rail vehicles.
Background technology
Along with railway extends to the extremely frigid zones such as Tibet, Qinghai, rolling stock inevitably faces ice and snow problem when running in the winter time.If the rolling stock that longtime running is in wind and snow area does not do special handling, after the snowflake flown upward creeps into the gap of the mechanical part such as bogie, electric coupler, setting expansion will hinder the properly functioning of these parts again；After Block brake sheet attachment ice and snow, brake efficiency will reduce when braking starts, and affects train braking reliability；If car door is freezed by snow water, the station boarding time will be affected and then affect train running on scheduled time operation.The ice cube that operationally locomotive drops also can cause the damage of line fittings.Visible, extremely frigid zones sleet in winter can bring very serious impact to railway transportation.But China's most area, especially the area of railway netting twine prosperity belongs to temperate continental climate, and winter generally dries few snow, the therefore experience relative deficiency of railway anti-ice snow defence.Spring transportation in 2008, the running order of Chinese Railway is just upset by a precipitate freezing rain and snow disaster, also reflects the shortcoming of China Railway field ice prevention and snow removing technology and equipment.
Current train deicing, mainly by the method such as beaing, hot water washes away, also easily causes the damage of underbody parts while of inefficient.
Spraying anti-freeze fluid is the effective ways preventing from freezing bottom rolling stock.The prior art that can use for reference includes Snow Agent that road inorganic salt is main component and aircraft alcohols is the anti-freeze fluid of main component.But, inorganic salts Snow Agent has very big corrosivity；Rail vehicles bottom most portion is hardware, it is clear that above-mentioned inorganic salts anti-freeze fluid is unsuitable for railway locomotive.It addition, environmental factors is also need to consider.Railway is up to hundreds of to thousands of kilometers, and the extremely frigid zones such as Tibet, Qinghai is also the area of ecology fragility, and the adverse effect of deicing salt on environment can affect whole Along Railway area along with the operation of train.Owing to the railway transportation time is longer, it is attached to for a long time bottom rolling stock therefore it is required that anti-freeze fluid can be tried one's best.And aircraft anti-icing liquid needs behind aircraft traverse troposphere all by stripping, so aircraft alcohols anti-freeze fluid adhesive force is relatively low.Obviously, because using environment different, the anti-freeze fluid of aircraft is also unsuitable for rail vehicles Anti-freezing.
