Particular surfactants are known to reduce the surface tension between washing fluid and machine oil attached to the surface of metallic parts to almost zero. Such surfactants can, therefore, cause “spontaneous emulsification,” in which emulsification takes place without the need to apply such mechanical force as agitation or scrubbing. Leveraging this process, we developed a cleaning technology that is excellent in removing grime, including the grease and other foreign substances that cling to precision equipment components after processing.
By optimally selecting and formulating such agents as surfactants, penetrants and solvents, we have developed a technology of forming stable micro-emulsions in water. The penetrability and solubility of this micro-emulsion technology enables the cleaning of liquid crystal material sandwiched between two glass substrates only 3μm apart.
We have developed a detergent that optimizes the actions of alkalines and chelating agents while enhancing the detachability of abrasive agent particles and their zeta potential. Consequently, this detergent removes and prevents the redeposition of such micro-particulate grime as colloidal silica to hard disk substrates.
