Abstract
A composite ice and snow thawing agent is prepared from calcium chloride and/or magnesium chloride and/or sodium chloride and/or urea, and at least three of sodium benzoate, sodium molybdate, sodium triphosphate, sodium tetraborate and sodium metasilicate. Its advantages are low corrosion to metal and concrete and promoting growth of plant.
Description
Compound sleet melting and snow removing agent ice-melt snow removing effect is remarkable, widely applicable, and possesses the characteristics of novelty, creativeness and practicality, and the while compliance with environmental protection requirements now is described as follows particular content:
One, technical field: belong to the surface chemistry category, be organic and inorganic compounding salt technical field
Two, background technology
1, to inventing the understanding of " compound sleet melting and snow removing agent ":
(1) the selected main raw material of compound sleet melting and snow removing agent has: industrial chemicals such as calcium chloride, magnesium chloride, sodium-chlor, urea, Sodium Benzoate, Sodium orthomolybdate, Tri sodium Phosphate, sodium tetraborate, Starso.These industrial chemicals are through optimum combination, theoretical investigation, and after a large amount of laboratory and application test, the common conclusion that draws is the attribute that the present invention has low plait point, and the low-temperature condition that is suitable for more than-23 ℃ uses down, and ice-melt snow removing effect is remarkable, can be according to different areas, different temperature, different geographical environments and different applications, adopt different formula combination, its coverage rate is comparatively extensive, is suitable for all cities uses to the north of the Yellow River.
(2) good environmental protection of the present invention can reduce the corrosion to metal and cement concrete effectively.
As everyone knows, contain a large amount of Cl in the halogen
-Ion and a spot of impurity SO
4 2-Ion, and these ion pair metals and concrete corrosion meeting increase along with the increase of concentration, therefore, in view of under-23 ℃ cold condition, we have adopted its low plait point in triturating be main raw material at calcium chloride more than-55 ℃ and the magnesium chloride more than-33 ℃, and make up with other seven kinds of feedstock optimizations, by compound prescription, in actual applications, reduced corrosion effectively to metal and cement concrete.
(3) the present invention promotes plant-growth, preserves the ecological environment
Because the long-term of halogen class Snow Agent used in a large number, will cause soil compaction, saltiness increases, and causes morbid state growth and even the death of trees.Plant to muriatic controlling index is: when the ratio of the saltiness of soil and the weight of soil less than 0.15% the time, plant normal growth; When ratio during at 0.15%-0.25%, plant just slightly is injured; Be that severe is injured when 0.25%-0.4%; Be that the degree of depth is injured when 0.4%-0.6%; Greater than 0.6% o'clock, plant was with death.In sum, we have selected the main raw material(s) as compound sleet melting and snow removing agent such as calcium chloride, magnesium chloride, sodium-chlor, urea for use.The present invention is reaching on the ice-melt snow removing obvious results basis, reduced extent of corrosion effectively to metal and cement concrete, promoted the growth of plants such as flower, grass, trees, shown that from the result of theory and practice compound sleet melting and snow removing agent has higher use value.
(4) scope of application is extensive, and snow removing usefulness is remarkable
Compound sleet melting and snow removing agent is irregular, the polygonal particulate state of 0.1～10mm; it mainly is applicable to the ice-melt snow removing in different kinds of roads, bridge, airport, square, garden, viaduct, People's Bank of China's overpass, park and greenery patches at the intersections, is suitable for extensive mechanize and sheds operation.
