METHOD AND DEVICE FOR DETECTING AND CONTROLLING THE LEVEL OF BIOLOGICAL CONTAMINANTS IN A COATING PROCESS |
摘要 |
The presence of biological contaminants in a liquid coating composition is determined by measuring the carbon dioxide content of the atmosphere above the liquid and comparing the measured carbon dioxide level to a baseline carbon dioxide level. A biocide can be added to the liquid when the measured carbon dioxide level reaches a predetermined value to control the level of biological contaminants in the liquid coating composition. |
