Winter snow, frost, and causing the ice on the road, by the passing
vehicles rolling after, but also the formation of strong ski layer, especially
in the expressway, the slope of the bridge, high-rise buildings back road, due
to the snow road slip caused many personal injury and vehicles destroyed a
major accident occurred, the economic loss is very great. To this end, people
pay more and more attention to the removal of snow. Since the 1990s, North
America, Japan and other developed countries strengthen snow removal operations
development very fast, especially the development of snowmelt agent pay more
attention to environmental protection type and efficient type, special type, to
replace the use of non green seawater and brine snowmelt.
First, the principle of melting snow
The calcium, sodium and magnesium in the snow melting agent absorb the
moisture in the snow, and the snow is quickly dissolved into water. During this
process, the concentration of calcium, sodium and magnesium in the road surface
is increased, and the water is not easy to freeze. As its freezing point is
very low, it will continue to absorb the water in the snow, so that their own
dilution, so that the snow state of the road soon be dissolved. After the
dissolution of the snow, with special mechanical cleaning, in a short time will
restore the normal flow of the highway. In addition, the magnesium calcium in
snow melting agent has the nature of moisture absorption and heat release, it
is in the process of absorbing water in the snow, it will release the heat of
dissolution, so that the effect of snow melting agent is stronger.
Two, several types of snow melting
1 all calcium type snow melting agent
Not only has the characteristics of
sodium and magnesium type, more snow, freezing point for 35 DEG C, more
suitable for cold areas of freeway, road and bridge slope, squares,
communities, parking and other places, the use convenient, easy to dissolution,
high efficiency, low freezing point, osmotic strong and sustained, rapid,
without damage to the asphalt cement pavement and minimal impact on plants,
more environmental protection, is exported to South Korea, Japan, the preferred
2 sodium magnesium type snow melting agent
To the quality of sodium chloride and
sodium chloride as the base material, after drying the mixture of moisture
absorption of magnesium chloride is very strong and. With a strong moisture
absorption, good effect and so on, the price is low, the freezing point of -28
C, suitable for cold area roads, bridges, highways, squares. Is currently the
first choice for the use of the Northeast Economic snow melting agent.
3 all magnesium snow melting agent
The freezing point is -28, which has
the characteristics of good moisture absorption, quick dissolution rate, low
impurity content, good fluidity, and can be used for melting snow in cold
regions, and can be stored for a long time without affecting the use.
Three, the use of snow melting agent
Under normal circumstances can be
used in three ways:
1: artificial sprinkling mode. The main way for no special throwing
equipment or dissolved water spraying vehicle unit, operation area is small,
but the use of flexible and convenient. Applicable to the factory, the unit
inside the hospital. Reference dosage: the temperature at -10 degrees Celsius
per kilogram of 6-8m2.
2: special machinery casting type. The application in road, bridge,
highway, with the use of spray, water gun, spraying vehicles, and other special
tools, can rapid snowmelt, a short period of time can restore smooth road.
3: special water soluble spray type. The snow melting agent and 3-4 times
of water to dissolve (stir even better), sprayed on roads, bridges, highways,
squares, etc., the dissolution rate is faster, more efficient snow melting,
suitable for large areas of snow.
