Description

Technical Field

[0001] The present application relates to the technical field of physical microporous foaming of polymer materials using supercritical fluids, and in particular to a foaming particle collection device. Background Art

[0002] Liquids whose temperature and pressure are both above the critical point are called supercritical fluids. Supercritical physical foaming technology uses inert gases in a fluid state under supercritical conditions as foaming agents. Through high temperature and pressure, the foaming gas is evenly infiltrated into the interior of the elastic plastic particles, thereby expanding the volume of the particles to several times the original size. This foaming technology does not use any chemical foaming agents and cross-linking agents, does not release or leave any harmful substances, is very environmentally friendly, and the elasticity and compression recovery properties of the beads are also better. Commonly used gases include carbon dioxide, nitrogen, etc.

[0003] The preparation process of supercritical carbon dioxide pressure-induced foaming is to place polymer materials and a certain proportion of liquid in an autoclave, introduce carbon dioxide gas into the autoclave, and pressurize and heat the autoclave to make its pressure higher than 7.38Mpa and temperature higher than 31°C. The set temperature is generally close to the softening temperature of the polymer material, and the carbon dioxide is in a supercritical state. The stirring paddle in the autoclave stirs the polymer material and the liquid in real time, and after a period of time, a homogeneous system of polymer material and supercritical carbon dioxide will be formed inside the polymer material. Then quickly open the pressure relief valve under the autoclave, and the water and polymer material in the autoclave will be ejected instantly. Through the pressure difference formed instantly, bubble nuclei are formed inside the polymer material and expand and foam instantly to prepare polymer foaming materials.

[0004] During the foaming process, the material needs to be ejected instantly from a 7-15Mpa high-pressure pipeline. The material is ejected at an extremely fast speed, and the impact force on the bottom of the kettle is very large. At the same time, because the foaming particles have high elasticity, it is more difficult to collect the material. The high-temperature liquid ejected instantly from the kettle will not only bring danger to the operator, but also the high-temperature and high-pressure solid, liquid, and gas mixture directly enters the subsequent screening equipment, which is easy to cause equipment damage, prolonging the time for collecting the foaming particles, thereby reducing the collection efficiency of the foaming particles.
