Plastic microsphere surface ozone treatment device

Abstract

The invention provides a plastic microsphere surface ozone treatment device. A microsphere dispersion container in the device is provided with a sealing cover, the top end of a stirring rod is connected with an electronic stirrer in an inserted mode, and the lower end of the stirring rod penetrates through the sealing cover to be located in the microsphere dispersion container. A motive sealing adapting part is fixed on the sealing cover, and the stirring rod is connected with the sealing cover through the motive sealing adapting part. The sealing cover is provided with a microsphere injection opening, and the sealing cover is connected with the microsphere dispersion container in a sealed mode. An ozone dissolving tank is fixedly arranged on one side of the microsphere dispersion container, and a plurality of wall holes are formed in the common container wall. The top end of the ozone dissolving tank is provided with a cover which is provided with a liquid inlet, and the lower end of an ozone input pipe extends to the tank bottom of the ozone dissolving tank through the cover. The plastic microsphere surface ozone treatment device is easy and convenient to operate, easy to control and capable of effectively preventing local contact ozone bubbles and plastic microspheres, avoiding mutual adhesion among PS solid cores in the large-size double-layer sphere preparation process, achieving uniform modification of polymer microsphere surfaces and improving the microsphere dispersity in the double-layer sphere preparation process.

Description

technical field [0001] The invention belongs to the technical field of polymer microsphere preparation, and in particular relates to an ozone treatment device for the surface of plastic microspheres, which is suitable for uniform ozone modification on the surface of polymer microspheres. Background technique [0002] With the development of high-power lasers in China, the diameter requirements for multi-layer polymer target pellets used in laser inertial confinement fusion physics experiments are also increasing. Therefore, the research on the preparation technology of large-size double-layer hollow microspheres is extremely important. However, the core of the PS-PVA double emulsion is a solid PS microsphere, which is not easily deformed. At the same time, the interaction between the hydrophobic PS core and the hydrophilic PVA is very weak, so when the PS ball coated by the PVA liquid film is in the oil When moving in the phase, once the deformation of the outer PVA liquid f...
