Abstract

The invention relates to a water-based foam stabilizer, a preparation method and a water-based foam system with super high stability. The water-based foam stabilizer is a water-soluble macromolecular surfactant A dissolved in water to form a transparent solution with a mass concentration of 0.1-1 wt%. The invention also provides a preparation method and application of the water-based foam stabilizer. The surfactant A can be adsorbed on the gas-liquid interface to stabilize the foam, the gas-liquid interface has a high coverage, and the formed foam liquid film has a strong liquid holding capacity and high foam stability. It is used for nitrogen, carbon dioxide, oxygen, air, flue gas In the water-based foam system in the gas phase, such as decarbonized flue gas, etc., it can maintain excellent foam stability even under harsh conditions such as carbon dioxide as the foaming gas or the presence of crude oil.

Description

technical field

[0001] The invention relates to a water-based foam stabilizer, a preparation method and a water-based foam system with super high stability, and belongs to the technical fields of oilfield chemistry, daily chemistry, mineral processing and the like. Background of the invention

[0002] Foam is a polydisperse system of a mixture of gas and liquid, where the liquid is the continuous phase and the gas is the dispersed phase. Water-based foam is widely used in our daily life, such as shampoo, toothpaste, facial cleanser, shower gel and other daily chemical products, as well as in food and beverages such as beer, coffee, and ice cream. The presence of foam enhances the quality of the product, improving the mouthfeel, skin feel or aesthetics of the product. Foam is also used for fire suppression, which creates a blanket effect that reduces the production of combustible gases, helps to trap oxygen, and cools fuel surfaces.

[0003] In the industrial field, the dif...
