3 Antifoaming agent

1. Introduction
3 antifoaming agent is modified dimethyl siloxane with the characteristics of non-volatile, non-toxic, odorless. It is milk white liquid and insoluble in water. It can be dissolving in organic solvent, such as aliphatic hydrocarbon, with well heat stability (stable under 200℃). It has well antifoaming effect with little dosage. It has been widely used in the Liaoning Chemical Factory with reliable performance.

3. Use
  • Use: It is mainly used in the arene that Sulfolane is the extraction solvent, and it is also used in other areas.
    Using method:
    1). Antifoaming agent confecting: confecting as the given burdening, 5-10Vol% toluol solution. Adding toluol in the solution, and then add 3 antifoaming agent.
    2). Using metering pump to add antifoaming agent quantitatively, and add at inlet of stripping tower.
    4. Packing, storage and transportation
    Packing: Galvanized drum with the net weight of 20kg.
    Storage and transportation: Stored at cool and dry place. Far from toxic goods, acid and alkali. Transport it as the rules of general dangerous goods.
