Description
Technical field
The utility model belongs to the snow melt clearing ice technology field of urban road, airport roadway and highway etc., and in particular to arrives
A kind of novel test device of the minimum temperature in use of Accurate Determining liquid deicing salt.
Background technology
The highways and streets of China's most area and airport roadway etc. can all be influenced be subject to ice and snow in the winter time.Road
Accumulated snow freeze do not only result in interruption of communication, be also easy to trigger traffic accident, bring serious economy and life and property loss.Mesh
Before, it is to dispense deicing salt that most snow melt deicing modes is used in worldwide, and according to incompletely statistics, the whole world about makes every year
With 30,000,000 tons of deicing salts, and increased trend year by year is also presented in deicing salt dosage.Different according to form, deicing salt can be divided into solid
Two class of state and liquid deicing salt.Compared to solid particle deicing salt, liquid deicing salt can realize mechanical sprinkling, have contact area
Greatly, the advantages of uniform, snow melt deicing efficiency is high is dispensed, the usage amount of deicing salt while snow melt deicing is ensured, can be reduced,
Mitigate the harm caused by engineering construction thing and surrounding enviroment, therefore obtain more and more promoting and application.
Different from solid deicing salt, otherwise liquid deicing salt will lead to not spray when in use it is ensured that it will not be solidified
Spill and use.Therefore, exist《Road deicing deicing salt》(GB/T 23851-2009)、《Deicing salt》In (DB11/T 161-2012)
Using the freezing point (solidification point) of liquid deicing salt as the technical indicator that must be surveyed, the method foundation of freezing point is tested《Engine coolant
Freezing point test method》(SH/T 0090-1991) or《Jet fuel freeze determination method》(GB/T 2430-81), both tests
Principle is respectively:It is freezing point that the former, which measures the temperature that sample starts to crystallize,;The latter, which then measures sample, to be occurred after crystallizing, then makes it
Heating, the minimum temperature that the hydro carbons crystallization being originally defined disappears is freezing point.
Applicant is on the basis of a large number of experiments, and analyzing above-mentioned freezing point index and its test method, there are following defect:
(1) only some belongs to the liquid deicing salt of crystal when temperature drops to a certain degree, and there are obvious knot
Crystalline state;And for example most organic deicing salt of a part of liquid deicing salt belongs to noncrystal, when the temperature drops, its liquid is got over
Come more sticky, gradate as solid-state, in the process without obvious crystalline state, also there is no fixed freezing point (solidification
Point), therefore, above-mentioned test method does not apply to simultaneously.
(2) freezing point index is not strong with the use relevance of liquid deicing salt in itself.The occupation mode of liquid deicing salt is main
For spraying operation, and almost all of liquid deicing salt its viscosity when temperature declines all can constantly become larger, when its viscosity is very big
When, it can not just realize normal spraying operation, illustrate that liquid deicing salt just can not be normal when environment temperature drops to a certain degree
Use, i.e. the minimum temperature in use of liquid deicing salt is directly related with its viscosity, not consistent with freezing point, usually above ice
Point.
