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.
