The inorganic Snow Agent of composition, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride villaumite, therefore also commonly known as " change cryosel ", its
Advantage is cheap, just corresponds to the 1/10 of organic Snow Agent, but it significantly has the disadvantage to large-scale public infrastructure
Corrosion be quite serious, long-term use can cause afforestation vegetation mortality, and highway, bridge concrete road surface are caused sternly
The corrosion failure of weight, and with the snow melt for being doped into Snow Agent and earth's surface is penetrated into, rivers and underground water can be also polluted, sternly
Ecological environment is destroyed again.
Therefore, developing cheap, harmless, efficient environment-friendly snowmelt agent turns into the task of top priority.Environment-friendly snowmelt agent refers to production
Sodium chloride-containing or the Snow Agents of the compositions such as special-purpose protecting agent is not specifically added in villaumite in product, to reduce Snow Agent to road
And the influence and destruction of environment.Such as, corrosion inhibiter, corrosion inhibitor or preservative etc., but the protective agent added are added in snow melt salt
Also it is generally the salts such as nitrite, acetate, therefore such environment-friendly snowmelt agent can typically be only used to Reinforced Concrete Bridge, without
Non- bridge face can be used for, once and Snow Agent with water penetrate into soil still can severe contamination underground water, so for strict simultaneously
Environment-friendly snowmelt agent can not be referred to as.As Chinese patent CN104293298A and disclosed a kind of efficient villaumite snow melt of low corrosion
Agent, although with the addition of high-efficient corrosion inhibitor in the Snow Agent, can largely slow down road pavement and corrosion of metal, but for a long time
From the point of view of, still there is serious corrosion risk in road pavement, metal material containing substantial amounts of villaumite to the product, and to neighbouring vegetation
Cause large effect.It can be seen that, it can not fundamentally solve to melt using Snow Agent product made from the protectant mode of addition
Avenge the harm of agent.
Therefore, currently for the requirement of environment-friendly snowmelt agent, except require snow melt add that dosage is small, use cost it is low in addition to,
More importantly road pavement, green plants and the basic fanout free region of communal facility, and the corruption of traditional product is solved from source
Erosion problem, reduces influence and destruction of the Snow Agent to road and environment to greatest extent；And the product of snow melt residual is required as far as possible
Plant production can be promoted, secondary utilization is realized, so could fundamentally prevent the harm of Snow Agent.
Chinese patent CN104031610A discloses a kind of environment-friendly snowmelt agent, and its raw material composition includes water, ethanol, sugarcane
Sugar, Soquad, ethylene glycol, glycerine, acesulfame potassium, sodium tripolyphosphate, Aspartame, calgon, methanol and threose
Alcohol.The Snow Agent snow melt efficiency is higher and Snow-melting speed fast, and tests the proof Snow Agent not polluted source, does not corrode building
And road surface, plant and aquatic animal are not injured, soil pH is not destroyed, the salinization of soil is not resulted in, with the preferable feature of environmental protection
Energy.But, more poisonous and volatile methanol has been used in the Snow Agent, its environmental-protecting performance has been had a certain impact.
