specific Embodiment approach

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] figure 1 Medium Surfactant C 12 -3-C 12 2[FeCl 3 Br - ] The concentration is 1.0mM, the surface tension is measured by the pendant drop method, and the strength of the applied magnetic field is about 1.3T. The external magnetic field can significantly affect the surface tension of the surfactant, indicating that the synthesized surfactant has certain magnetic properties.

[0024] The liquid drainage half-life of the foam refers to the time it takes for half of the liquid (50ml) to separate out during the defoaming proces...

Embodiment 1

[0027] Magnetically responsive multiphase foam system, 0.1g octyl-beta-D-glucopyranoside (APG) and 0.001g magnetic cationic surfactant C were added to 100mL deionized water 12 -3-C 12 2[FeCl 3 Br - ], and then add 1.5g of silica nanoparticles, and stir at 8000rmp at high speed for 3 minutes to form a stable heterogeneous foam system.

[0028] About 430mL of foam can be produced, and the half-life of the foam is about 4500s in the absence of a magnetic field. Compared with Comparative Example 2, it can be seen that the foam has better stability. Under the action of a 0.4 Tesla magnetic field (NdFeB magnet), the foam system can completely defoam within 237s. Compared with Comparative Example 1, it can be seen that the foam is magnetically responsive and can rapidly defoam under the action of a magnetic field. Example 2:

Embodiment 2

[0029] Magnetically responsive multiphase foam system, 0.25g octyl-beta-D-glucopyranoside (APG) and 0.003g magnetic cationic surfactant C were added to 100mL deionized water 12 -3-C 12 2[FeCl 3 Br - ], and then add 1.5g of silica nanoparticles, and stir at 8000rmp at high speed for 3 minutes to form a stable heterogeneous foam system.

[0030] About 430mL of foam can be produced, and the half-life of the foam is about 4500s in the absence of a magnetic field. Compared with Comparative Example 2, it can be seen that the foam has better stability. Under the action of a 0.4 Tesla magnetic field (NdFeB magnet), the foam system can completely defoam within 232s. Compared with Comparative Example 1, it can be seen that the foam is magnetically responsive and can rapidly defoam under the action of a magnetic field. Example 3:

Abstract

The present invention relates to a multiphase foam system, in particular to a magnetic response type multiphase foam system and a preparation method thereof, comprising the following components: octyl-beta-D-glucopyranoside (APG) 0.1-0.5wt%, magnetic cation Surfactant C12‑3‑C12·2[FeCl3Br‑] is 0.001‑0.010wt%, silica nanoparticles is 1.2‑1.5wt%, and the rest is water. The magnetically responsive multi-phase foam system disclosed in the present invention can stabilize the foam system and endow the foam system with magnetic responsiveness, and use an external magnetic field to realize the control of the foam defoaming time, so that the foam system can be concentrated and quickly burst in a short time, expanding The scope of application of the foam system in occasions that require a specific defoaming time can be applied to industrial production occasions that require both a stable foam system and controllable defoaming in a short time.

Description

technical field [0001] The invention relates to a multiphase foam system, in particular to a magnetic response type multiphase foam system and a preparation method thereof. Background technique [0002] Foam is a dispersion system formed by dispersing insoluble gas in liquid, in which the insoluble gas is used as the dispersed phase and the liquid is used as the dispersion medium. With the widespread use of surfactants, foam systems have gradually received widespread attention. Foam systems are now widely used in food, cosmetics, oil extraction, mineral extraction, fire fighting and other fields. Emerging industrial applications generally use foam as an intermediate to produce porous materials, and are also used to produce thermal insulation materials and low specific gravity materials, as well as in medicine to produce artificial implants and scaffolds for drug delivery and tissue engineering. [0003] Foam is a thermodynamically unstable system. The instability of foam c...
