Problems solved by technology

[0004] 1. The temperature is unevenly heated. Some foaming experiments require heating with an oil bath, and some require heating with a heating tube. Therefore, when the experimental requirements are different, a single heating design and a device lacking a stirrer will make it difficult for researchers to obtain the expected experimental results.
[0005] 2. The airtightness is low, and the support frame is difficult to balance. First, in the traditional device, the material bracket is connected to the autoclave or supported at the bottom of the autoclave, which easily causes problems such as unstable support and low experimental efficiency.

Embodiment Construction

[0069] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0070] Such as figure 1 As shown, the supercritical CO 2 The fluid foamer includes a sealed cylinder 1, a pressurizing device 2, and a heating medium stored in the sealed cylinder 1, and the heating medium is oil.

[0071] Such as Figure 1-2 As shown, a cantilever support tube 3 is connected to the inner wall of the sealed cylinder body 1, and the cantilever support tube 3 is in an L-shaped structure. The cantilever support tube 3 includes a horizontal section and a vertical section connected with the horizontal section. The segment axis coincides with the axis of the sealed cylinder 1.

[0072] One end of the horizontal section away from the vertical section is fixed on the inner wall of the sealed cylinder 1 and communicates...

The invention has the advantages of improving the foaming quality.

Description

technical field [0001] The invention belongs to the technical field of foaming, in particular to a supercritical CO 2 Foaming methods for fluids. Background technique [0002] Supercritical CO 2 The foaming device is a crucial device for the preparation of polymer porous materials. The experimental equipment is mainly composed of four parts: pressurization device, autoclave, heating device and pressure relief device. The preparation of different polymers has different requirements and conditions for the equipment. [0003] Traditional supercritical CO 2 There are mainly the following problems in the preparation of polymer porous materials by foaming devices: [0004] 1. The temperature is unevenly heated. Some foaming experiments require heating with an oil bath, and some require heating with a heating tube. Therefore, when the experimental requirements are different, a single heating design and a device lacking a stirrer will make it difficult for researchers to obtain...
