Description

[0002] Most of the existing ovens are static drying, and the objects to be dried or heated are directly placed in the oven. However, for the epoxy resin to be cured with nanoparticles added, when nanoparticles are added to the epoxy resin, mechanical stirring, ultrasound and other means are used to promote the dispersion of nanoparticles in the epoxy resin. But after the epoxy resin liquid containing nanoparticles is poured into the mold, the mold is usually left to stand in the oven to complete the curing process. In this process, the nanoparticles will settle at the bottom of the mold due to gravity, and it is difficult to achieve the purpose of being evenly dispersed in the epoxy resin. Therefore, there is an urgent need for a curing oven that can still evenly disperse the system to be cured during the curing process. Utility Model Content
