Description
Technical field
The utility model belongs to the snow melt clearing ice technology fields such as urban road, airport roadway and highway, is specifically related to a kind of test unit of novel, efficient detection Snow Agent deicing or snow melting ability.
Background technology
The highways and streets of China's most area and airport roadway etc. all can be subject to ice and snow impact in the winter time.The accumulated snow of road freezes and not only causes interruption of communication, also easily causes traffic hazard, brings serious economy and life and property loss.At present, adopt maximum snow melt deicing modes to be exactly spreading Snow Agent in worldwide, according to incompletely statistics, the whole world is annual approximately uses 3,000 ten thousand tons of Snow Agent, and Snow Agent consumption also presents the trend increased gradually.While a large amount of uses of Snow Agent improve snow melt deicing efficiency, do great damage also to engineering construction thing and surrounding enviroment, this problem more and more causes the attention of countries in the world.Therefore, in the urgent need to while guarantee snow melt deicing effect, reduce use amount, namely improve Snow Agent deicing or snow melting ability.On the other hand, the Snow Agent kind that Current Domestic uses is more, differs greatly, and being also badly in need of can the test unit of accurate evaluation Snow Agent deicing or snow melting ability and test method.The deicing or snow melting ability measuring or evaluate Snow Agent accurately both can optimize the remarkably productive Snow Agent of snow melt in numerous product, rational Snow Agent consumption can be determined according to the snowfall of reality again, avoid too much spreading Snow Agent to cause excessive influence to engineering construction thing and surrounding enviroment.
The method of testing of existing Snow Agent deicing or snow melting ability is shown in " road deicing Snow Agent " (GB/T23851-2009), and concrete test procedure is: the sodium chloride solution of (1) configuration standard concentration and Snow Agent solution to be determined; (2) in the same diameter of 150ml volume and two porcelain crucibles of height, add 100ml water respectively, be placed in the constant temperature oven of-10 DEG C ± 1 DEG C to freezing, and weigh; (3) sodium chloride solution of-10 DEG C ± 1 DEG C and Snow Agent solution are poured in porcelain crucible respectively, in constant temperature oven, place 0.5h; (4) pour out the liquid in porcelain crucible, weigh the quality of porcelain crucible and residue ice cube; (5) arrangement calculates the deicing or snow melting ability of Snow Agent relative to normal concentration sodium chloride solution, and numerical value represents with %.Analyze above-mentioned test method and there is following defect: (1) freezes the ice shape disunity, irregular of system in porcelain crucible, after pouring 25ml Snow Agent into, can not contact completely with ice cube, and under different ice cube shaped, contact area is also different, directly can affect the precision of this test, in practical operation, identical Snow Agent parallel experiment result difference is larger.(2) operation of pouring out the liquid in porcelain crucible and weighing, generally can only take out constant temperature oven, carries out under room temperature environment, and the time of pouring liquid does not have concrete regulation, and in practical operation, dumping time is different, larger on test findings impact; (3) to the mensuration of different Snow Agent deicing or snow melting ability, the sodium chloride solution with normal concentration is all needed to compare, also increase test error to a certain extent, and utilize the deicing or snow melting ability of the different Snow Agent of this index characterization, discrimination is Shortcomings also.
