1) Strong electrolyte inorganic salts:
a) Chlorine salts: additives with chlorine salt as antifreeze component;
b) Chloride salt rust inhibitors: Admixtures that use chlorine salts and rust inhibitors as antifreeze components;
c) Chloride-free salts: admixtures that use inorganic salts such as nitrite and nitrate as antifreeze components.
2) Water-soluble organic compounds: additives that use certain alcohols and other organic compounds as antifreeze components.
3) Compounds of organic compounds and inorganic salts.
4) Compound antifreeze: an antifreeze component combined with early strength, air entrainment, water reduction and other additives.
