1. The data using underground water and distrilled water show the following. It is more effective to add the solution standard Hydroplus 10 to distrilled water, because hardness value is remarkably low and it is much stable. In the case of underground water, the volume is varied along the season and the location.
2. Here are the following results of 10%∼20% isopropyl alcohol contained in dampening solution No2 and No3.
- 10% and 20% of pH volume were the same. In other words, the first volume of pH were decreased and the next volume of pH were increased.
- Percent of transfer was decreased at 10% or 20%.
- The characteristic graph of Percent of transfer doesn't comply to the density of isopropyl alcohol. But it is lower than the volume of the solution contained in 10% of isopropyl alcohol.
3. The contact angle doesn't vary in dampening solution which has multiple elements. The potential error comes from the measurement.
