Introduction
Mineral oils are widely used in industrial product production processes such as cutting, lubrication and cooling. During the production process and when the product is completed, the product
Any remaining oil on the surface needs to be removed. The cleaning agents mainly used in these industries, such as hydrocarbon cleaning agents, bromine cleaning agents and alkaline cleaning agents, can cause
Cause environmental problems such as ozone layer destruction and water pollution.
As an environmentally friendly technology, micro-bubble technology that does not use cleaning agents has been widely used. Microbubble cleaning technology can
It uses less water and does not use chemicals, thereby enabling sustainable use of resources and improving energy conservation and safety levels.
"Cleaning Applications of Micro Bubble Technology" aims to standardize the generally applicable principles and requirements in the field of cleaning applications of micro bubble technology.
