Coated ice melting compositions
Ice melting compositions, methods for manufacturing ice melting compositions, and methods for melting ice are disclosed. The ice melting compositions can include a coarse deicing particle nucleus and a fine deicing particle coating substantially surrounding the coarse deicing particle nucleus. The fine particle coating can be attached or bonded to the coarse particle nucleus with a binder. The coarse particle nucleus and the fine particle coating can have a variety of particle sizes.
1. An ice melting composition comprising:
a coarse deicing particle nucleus,
a fine deicing particle coating substantially surrounding the coarse deicing particle nucleus and bonded to the coarse deicing particle nucleus with a binder, wherein the binder is a sodium chloride brine with yellow prussiate of soda,
wherein the composition comprises from about 84% to about 90% of the coarse deicing particle nucleus, from about 2% to about 4% of the binder, and from about 8% to about 12% of the fine deicing particle coating.
2. The ice melting composition of claim 1 , wherein the coarse deicing particle nucleus comprises sodium chloride.
3. The ice melting composition of claim 1 , wherein the fine deicing particle coating comprises fine particles of sodium chloride.
4. The ice melting composition of claim 1 , wherein the fine deicing particle coating consists of fine particles of sodium chloride.
5. The ice melting composition of claim 1 , wherein the sodium chloride brine is saturated.
6. The ice melting composition of claim 1 , wherein the coarse deicing particle nucleus has a particle size range from about 500 μm to about 10,000 μm and the fine deicing particle coating comprises fine deicing particles having a particle size range from about 20 μm to about 600 μm.
7. The ice melting composition of claim 1 , wherein the fine deicing particle coating comprises fine deicing particles having a particle size range from about 100 μm to about 300 μm.
8. The ice melting composition of claim 1 , wherein the binder comprises about 2,000 ppm to about 5,000 ppm of the yellow prussiate of soda.
