Process for cleaning PVC
The cleaning process was carried out using an ultrasonic cleaning machine with a 3% concentration of Galvex 17.30 cleaning fluid, which is a multipurpose degreaser specifically designed for ultrasonic cleaning. The cleaning solution was prepared by diluting the Galvex 17.30 in tap water and heated to the required temperature. The tank was then allowed to degas to remove any trapped air bubbles that may interfere with the cleaning process. A single part was placed in the tank and cleaned for 3 minutes using the ultrasonic cleaning machine. The cleaning process was optimised for maximum results. After the cleaning process, the part was rinsed in the Versa 50 rinse tank for a cycle time of 1 minute. The rinse tank was equipped with an auto-purge feature, which allows fresh tap water into the tank for the length of the treatment time. The benefit of this feature is that it removes soap and residue carryover, which can cause staining of the cleaned parts. When the level of the rinse water reaches the overflow weir, it is connected to the drain, preventing the rinse water from becoming polluted. After rinsing, the part was dried in a hot air dryer at 70°C for 10 minutes. Upon inspection, there was no visible oil contamination remaining, and there was no staining. The remaining 5 parts were cleaned as a batch. The cleaning time was increased from 3 to 5 minutes to ensure optimal cleaning results. The rinse cycle was 1 minute with a 10-minute dry as before. The results were good, with no visible traces of contamination or staining.
