Abstract

This system, with a heated mixing reactor, uses a plurality of interchangeable containers adapted to be placed in a jacket and heated with circulated hot water. In the manufacture of organic vehicle systems for formulation into screening paste, suitable organic resins are dissolved in organic solvents. This is generally accomplished by stirring the components together in a heated vessel until completely dissolved. In accomplishing this objective, the following important requirements must be met: (1) The process must be heated significantly above room temperature to speed the dissolution of the resin in the solvent. (2) The heating medium must be heated water because of the flammability of the solvents involved in the process.

Interchangeable Vessel Stirred Tank Reactor

This system, with a heated mixing reactor, uses a plurality of interchangeable containers adapted to be placed in a jacket and heated with circulated hot water. In the manufacture of organic vehicle systems for formulation into screening paste, suitable organic resins are dissolved in organic solvents. This is generally accomplished by stirring the components together in a heated vessel until completely dissolved. In accomplishing this objective, the following important requirements must be met: (1) The process must be heated significantly above room

temperature

to speed the dissolution of the resin in the solvent.

(2) The heating medium must be heated water because of the

flammability of the solvents involved in the process.

(3) The stirring rate, as well as the temperature, must be

controlled to speed the process without causing

degradation to the chemicals.

(4) Since the process is at elevated temperature, the

solvent

vapors must be contained during the mixing operation.

(5) The paste systems which incorporate the various organic

vehicles

must be maintained free of contamination, which requires

that

the paste vehicles be cleaned after every batch.

(6) Safety standards must be adopted which restrict the

exposure of

personnel to cleaning solvents, such as

perchloroethylene,

during cleaning and maintenance of the equipment.

This system utilizes a plurality of mixing containers of a stadardized size similar to container 10. Container 10 is loaded into...
