In the usual production of electric locks, tap water is used in most cases whether it is preparing lock grooves or cleaning locks. Therefore, many electric lock experimenters did not put forward strict requirements on water quality, so they prepared and cleaned with tap water, thinking that this was closer to the production situation, and the results were comparable. This is actually a misunderstanding.
Electric lock experiments should have clear quality requirements for water quality, that is, distilled water or deionized water should be used to prepare experimental liquids or various standard solutions, and deionized water should also be used for the last process of cleaning after locking. Washing with water is to obtain a result that is closer to the process standard requirements or theoretical design, and to be used as a reference for future expansion tests or production pilot tests. This is also done in order to eliminate as far as possible the unknowable influencing components brought into the lock liquid due to unqualified water quality, and to increase the difficulty of the electric lock experiment.
Even if the deionized water labeled as distilled water or purified water is used, a qualification test must be done before use to prevent the unqualified resin from being regenerated from bringing water with a pH value that does not meet the requirements into the lock tank. .
