The Key to Sustainability - Part 2

摘要

The discovery phase of this program included a criterion of replication. It was important to produce similar polished surfaces throughout the country in a controlled environment. It was critical that the same test methods be used throughout the discovery phase and that progress was monitored on a daily basis. During site evaluations, the lowest profile tested was equivalent to a 150-grit metal bond. A 3-head planetary grinder with an adequate amount of tooling was used as the base for the polishing process. Of the five locations evaluated, it was determined that only two used the same process so four test pads were produced for this phase. Each test area was confined to 100 square feet. All elements of the specification were followed, including the same chemical densifiers, sealers, grinding/polishing equipment, and the final gloss reading was to achieve a minimum 40 gloss using a Horiba IG320.
