Abstract
Description
Technical Field
[0001] The utility model relates to the field of auxiliary equipment for polymer material foaming, in particular to air filtering and purifying equipment for polymer material foaming. Background Art
[0002] When polymer materials are physically foamed in a reactor, nitrogen and / or carbon dioxide are generally required to be introduced. For example, the inventor submitted an application number of 201911333408.X to the State Intellectual Property Office of China on December 23, 2019, and the name is a polymer airbag sole and a method for manufacturing the same. The invention patent application has been authorized. In the patent technical scheme, it is recorded that the embryo sole is placed in a reactor, and then nitrogen and carbon dioxide are introduced into the reactor. The embryo sole expands and foams rapidly. Actual production has proved that qualified airbag soles can be produced according to the process of this scheme. However, the disadvantage is that a large amount of nitrogen is required to be equipped with a nitrogen delivery system, which is costly, and the nitrogen delivery system is generally large in size and occupies a large space in the factory. In addition, the temperature of a large amount of liquid nitrogen is extremely low, and contact with liquid nitrogen may cause frostbite, which poses certain safety hazards. Therefore, if air can be used to assist the foaming of polymer materials, it will not only be convenient to obtain materials and reduce costs, but also safer. However, the disadvantage of using air to assist foaming is that the factory air contains a lot of dust and high humidity, which will directly affect the success of foaming. Utility Model Content
