Description

[0002] Surfactant is a substance that can significantly change the interfacial state of its solution system by adding a small amount.

The top of the second pressure spring 211 is fixedly connected with a sealing piston 210, and the side of the sealing piston 210 is movably connected to the inner wall of the side of the mounting cylinder 201. The side of the sealing piston 210 is fixedly connected with a sealing ring 212. The top of the sealing piston 210 is fixedly connected with a first pressure spring 209, and the top of the first pressure spring 209 is fixedly connected with a connecting rod 203. The side of the connecting rod 203 is provided with a scale. The feed pipe 104 is connected with the corresponding raw material tank. During use, the second pressure spring 211 pushes the sealing piston 210 upward, and the first pressure spring 209 pushes the sealing piston 210 downward to make the sealing piston 210 and the center position of the mounting cylinder 201. The negative pressure device draws the internal gas of the reactor body 101 through the air guide pipe 102 to reduce the internal air pressure of the reactor body 101.

During use, the air pressure inside the reactor body 101 changes.
