Cleaning of the territory in winter is not only clean, but also safe paths along which it is pleasant to walk in any weather. But how to keep everything in perfect order when frost has filled almost everything around? So, five ways to deal with ice.
The first way is table salt. The advantages of this method are low cost and availability. The downside is the high activity of the substance. Salt copes well with the ice crust, but it can lead to corrosion, spoil shoes and rubber mats at the entrance to the facility, etc. This method is relevant in the CIS countries.
The second is the friction method: sand and stone chips. Its advantage is environmental friendliness and economic benefit, since materials can be reused. The main disadvantage is that sand and crumbs do not linger on the roads for long: they are carried by the wind, by the feet of pedestrians, by car wheels. The friction method is actively used in Europe.
The third way to deal with ice is the Torgeir Waa method. It is efficient, environmentally friendly and cost-effective, but it requires special equipment to implement it. The essence of the method consists in spraying a mixture of fine sand with hot water on the road. This method is especially popular in Sweden.
The fourth method is the use of alternative chemicals such as magnesium chloride, calcium magnesium acetate and calcium chloride, and urea (carbamide). Treatment with magnesium chloride is effective, however it is quite expensive and its corrosive properties are very high. Calcium-magnesium acetate and calcium chloride are an environmentally friendly method, but economically unprofitable and are suitable for dealing with ice only at an air temperature of at least -7 ° C. The advantage of urea in this situation is the environmental benefits. The disadvantages of this method are high cost (it is seven times more expensive than salt) and relatively low efficiency. The above methods are used mainly in the USA, Canada, New Zealand.
Cleaning closes the list of the top 5 methods of dealing with ice. It is environmentally friendly and does not require reagent costs. Environmentalists say that the most humane attitude towards nature is to fight bad weather with shovels and snow plows. This method is relevant in 230 countries around the world.
