(VE=desalts fully)
Use is used to prepare emulsion with lower device:
Initial container with agitator,
The high pressure that is used to have 2 grades of decompressing unit stirs evenly the charging pump of device feeding,
Emulsion is cooled to 10-20 ℃ heat exchanger.
The emulsifying agent (or emulsifying agent ligand (Emulgatorenpaar)) of in initial container, under agitation condition, inserting VE water in advance and all measuring.Add after the organosilane, the pH value is adjusted to pH7.5 by adding sodium bicarbonate.
