The coolant pH of the sum is a measure of its acidity or alkalinity.
Coolant pH is a measure of the concentration of hydrogen ions in the coolant.
A pH value below 7 indicates acidity, while a value above 7 indicates alkalinity.
Maintaining the correct coolant pH is important for the efficient operation of cooling systems.
Examples of coolant pH values: 7.0 (neutral), 6.0 (slightly acidic), 8.5 (slightly alkaline).
The hardness of water refers to the concentration of dissolved minerals, primarily calcium and magnesium.
Hard water contains high levels of calcium and magnesium ions
It can cause mineral deposits on plumbing fixtures and appliances
Soap does not lather well in hard water
Hardness is measured in parts per million (ppm) or grains per gallon (gpg)

Polymerization reaction consists of initiation, propagation, and termination steps.
Initiation step involves the formation of free radicals or ions that start the reaction.
Propagation step involves the growth of the polymer chain by the addition of monomers.
Termination step involves the end of the reaction, either by the consumption of all monomers or by the combination of two polymer chains.
Polymerization reactions can...
