Abstract
This disclosure features methods of forming chemical compositions. The method includes (1) mixing a plurality of continuous material flows in a mixing tank to form a chemical composition, each continuous material flow including at least one component of the composition; and (2) moving a continuous flow of the chemical composition to a packaging station downstream of the mixing tank. The mixing and moving steps are performed continuously. This disclosure also features systems that can be used to perform such methods.
Claims40
A method of forming a chemical composition, the method comprising:
- mixing a plurality of continuous material flows in at least one mixing tank to form a chemical composition, each continuous material flow comprising at least one component of the chemical composition, the at least one mixing tank having a volume of from about 10 liters to about 1500 liters, and the chemical composition being a polishing composition prepared from components comprising a diluent, an acid, a base, abrasive particles and optionally a salt;
- and
- moving a continuous flow of the chemical composition to a packaging station downstream of the at least one mixing tank;
- wherein the mixing and moving steps are performed continuously,
- wherein the material and chemical composition flows are in an in-process steady state;
- and
- wherein the mixing step in the at least one mixing tank comprises at least one mixing method selected from the group consisting of turbulent mixing of the material flows, mechanical agitation of the material flows, recirculation of the chemical composition, and a combination thereof.
A method of forming a chemical composition, the method comprising:
- mixing a plurality of continuous material flows in at least one mixing tank to form a chemical composition, each continuous material flow being a liquid and comprising at least one component of the chemical composition, the at least one mixing tank having a volume of from about 10 liters to about 1500 liters;
- and
- moving a continuous flow of the chemical composition to a packaging station downstream of the at least one mixing tank;
- wherein the mixing and moving steps are performed continuously,
- wherein the material and chemical composition flows are in an in-process steady state;
- and
- wherein the mixing step in the at least one mixing tank comprises at least one mixing method selected from the group consisting of turbulent mixing of the material flows, mechanical agitation of the material flows, recirculation of the chemical composition, and a combination thereof.
