Method for dissolving FINE RESIN

 
Method for dissolving FINE RESIN

Labo Scale

Methanol Charging(180g)

Methanol is charged into a flask (300cc).
 

FINE RESIN Charging(20g)

FINE RESIN Charging(20g)
After FINE RESIN is charged by bits , a condenser is attached.
 
 

Dissolving under Heating(55~60℃)

FINE RESIN is dissolved with water bath.
 

Filtration

Solution of FINE RESIN  is filtered by nyron-shears or wire-meshes, so that impurities are removed.

Real Machine Scale

Methanol Charging(180kg)

Methanol is charged into the dissolution tank with a condenser and  enclosed-jacket, and stirred.
 

FINE RESIN Charging(20kg)

FINE RESIN is charged by bits while stirring, and dispersed into  methanol.
 

Dissolving under Heating(55~60℃)

After FINE RESIN fully dispersed into methanol, hot-water is  supplied to jacket of the dissolution tank.
 

Filtration

Solution of FINE RESIN  is filtered by nyron-shears or wire-meshes, so that impurities are removed.

Notes on Equipments

  • It is desirable that material of equipments to contact vapor and/or solution is "SUS". (such as : inside of  dissolution tank, stirring wing, condenser, and thermometer e.t.c.)
  • The bottom valve of dissolution tank does not include short pypes as much as possible.
  • It is desirable that there is not much interval between stirring-wing and bottom of the dissolution tank.
  • When methanol is used as solvent, stirring-wing motor and other electrical equipments having high safety shoule be used.
