normalnie stosuje sie sól Na i czasami K, ale tylko do kilku stopni poniżej zera, bo przy niższej nie spełnia swojej funkcji
ale jest coś takiego:
- There are alternative substances that are more environmentally benign. Calcium magnesium acetate (CMA) has been used in some areas.
- Potassium acetate (KA) is also used as a chloride-free deicing agent.
- Ada County also uses magnesium chloride (MgCl2),
- test a calcium-magnesium-potassium acetate blend–CMAK. It worked OK.
- When temperatures get low, we’ll add liquid calcium chloride
- Alternatives to salt, such as the various "M-50" products (liquids created from byproducts of agricultural, beer, and distilled alcohols processing, combined with magnesium chloride),
- MAGic - The active ingredients in all versions are the carbohydrates, which lower the freeze point of the salt they’re added to. It will change magnesium chloride’s freezing point, allowing almost 20% more melting time.
- Calcium Chloride (CaCl2) Melts ice at temperatures of -25°F If used as recommended, will not harm vegetation
- Magnesium Chloride (MgCl2) Lowest practical temperature: 5°F If used as recommended, will not harm vegetation; however, MgCl2, on a percentage basis, contains 17-56% more chloride ion than other "salt"-type deicers
- Potassium Chloride (KCl) Lowest practical temperature: 12°F Will not harm vegetation
- Urea Lowest practical temperature: 15°F Will not harm vegetation
- Calcium Magnesium Acetate (CMA) Will work below 0°F Low toxicity and biodegradable
- Magic Minus Zero™ is a highly effective liquid de-icing agent made from a patented blend of magnesium chloride combined with an agricultural by-product of the distilling process (i.e. grain and/or sugar based) and is protected under U.S. patent #4,676,918. No other liquid ice melter can make this claim.
