REDUCED SALT PRECIPITATION IN CARBOHYDRATE CONTAINING BINDER COMPOSITIONS |
摘要 |
Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca2+, Mg2+, Ba2+, Al3+, Fe2+, Fe3+, etc.). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition. |

1. A method of reducing salt precipitation from a binder composition, the method comprising:
providing an aqueous binder solution comprising one or more carbohydrates; and adding a sequestrant for one or more multivalent ions to the aqueous binder solution, wherein the sequestrant reduces a precipitation rate for the multivalent ions from the binder composition. |
