摘要
Phase equilibria in K2CO3-H2O, Na2CO3-H2O, K2CO3-Na2CO3-H2O, K2CO3-(NH4)(2)CO3-H2O systems under temperatures ranging from 0 down to -36 degrees C are investigated. The carbonate compositions forming low-temperature eutectics are revealed. Their melting ability with respect to ice under temperatures -5 and -10 degrees C is determined. It was found that potassium carbonate is characterized by sufficient anti-icing properties. Potassium carbonate composition activity is determined with respect to metals. Efficient corrosion inhibiters are selected. It was found that potassium carbonate is aggressive with respect to cement concrete. Special protection is necessary, if potassium carbonate is used on cement concrete coatings.
