Intensity is big, and due to electroosmotic effect, latex particle is attached on anode through electrophoresis and forms film, and film moisture content at this time is low, glue
Piece compactness is good, and process energy consumption is low.
The electric field strength of extremely strong electric field roller pole extraction element described above: field minimum requires 30000v/m, purpose
It is that electroosmotic effect is strong, the moisture content for forming fine and close film is low, is less than the 40% of film quality containing water quality.When lower than 30000v/m
When, electroosmotic effect is weak, and dehydration efficiency is low, and under identical discharging speed, film stock thickness is thin, and moisture content is high, low output.In electric field strength
When stopping 2s for latex near 30000v/m spacing, water content can be lower than 40%.Meanwhile two interpolars for limiting extremely strong electric field are minimum
Spacing thickness 0.3mm, this is because when adhering to fine and close film on anode, enough spacing guarantee yield with this.When spacing reaches
15mm, film stock thickness is larger, and film stock thickness can be adjusted according to input and output material speed.
