For sidewalks, building managers to use most of the compounds of melting ice. There are plenty of ice melting products on the market today, then what's the difference? The active ingredient in the ice will melt, a combination of one or more of the following:
Sodium chloride (rock salt). This product is most often used, but limited effectiveness in extreme cold and ice did not melt below 20 degrees. Rock salt is not chemically attack concrete, cultured freshwater pearl, but it causes the corrosion of reinforcing steel and steel. This product is corrosive and can damage lawns, shrubs and trees.
Calcium chloride. This liquid is processed into pellets by removing water. It can quickly moisture from the atmosphere and can operate at very low temperatures down to -25 degrees. Costs are generally higher to melt the ice containing calcium chloride. Calcium chloride, may also damage lawns and other plants nearby.
Magnesium chloride. This is similar to calcium chloride. It is considered less corrosive, safe for use on concrete and less harmful to plants.
Potassium chloride and urea. They are usually found in chemical fertilizer, but this does not mean that they are safe around vegetation. At high concentrations, these chemicals are harmful to plants. Since urea does not contain chlorides, it is less corrosive and safe for use on concrete with rebar and around steel structures.
products of melting ice could also sand and clay additive with traction.
As products. Thawing all essentially the same job. Deicers work by attracting moisture to form a melt layer of sea water to produce heat in the ice. The product should reach the sidewalk effect. Once on the sidewalk of the "brine" can be spread on the ice and break the link with the road. When the ice loosened, it can easily increase the gap.
Melting rate depends on the rate of specific chemical reacts with moisture. ice melting products work best if applied before snow or ice accumulates. Spread ice melt thinly over the surface. In very cold weather, pearl pendant, it can be useful in the water, to add the product to begin the merger process, a chemical product solution and water really works.
To determine the efficacy of the product. One of the first things to consider is the temperature range of products in reasonable working hours, usually from 15 to 20 minutes. Calcium chloride works at colder temperatures and magnesium chloride and sodium chloride, also located in this category.
Stream must be a solution that will quickly solved efficiently. Since calcium chloride and magnesium chloride are liquids in their natural state, they quickly return to a liquid. Then, when these chemicals come in contact with water caused a reaction that generates heat to melt ice and snow. Through calcium chloride and sodium rank highest in efficiency for speed.
No matter who you decide to use the ice melting points, follow these tips:
* Do not use chemicals, follow the instructions on the label.
* Try not to melt it all. Prior to melt the ice, make sure that all accumulations of snow has been cleared or rejected.
* Wear gloves when applying ice to melt. Chemicals in some products can irritate the skin.
* Make sure the container tightly closed when storing the product. icing chemicals can absorb moisture and healing.
* Do not thaw on the new concrete, which is not completely healed.
* All products have some impact on the environment. If you have plants runoff may be damaged (see, sickly, dying plant back, browning of leaves) Flush area with plenty of water in the spring.
