  • Publication number: 20240123372
    Abstract: A process for treating aged oil by electron beam irradiation is disclosed, comprising the following steps: step 1, homogenizing the aged oil and then feeding the aged oil into a distributor; step 2, forming a liquid layer having a certain thickness on the distributor; step 3, installing and debugging an electron beam irradiation device on the distributor; step 4, installing and debugging a phased-array microwave emitter on the distributor after installing and debugging the electron beam irradiation device; step 5, turning on the electron beam irradiation device and the phased-array microwave emitter; and step 6, dividing the treated aged oil and then allowing the aged oil after dividing to enter an oil pool and a water pool for standing. Oil flows out from an upper layer of the oil pool, a lower layer of the oil pool flows back to an aged oil storage pool.

  • Patent number: 11866557
    Abstract: Composite articles that can resist discoloration or color changes are described. In some instances, the composite articles can include a compounded material that is substantially free of an antioxidant that changes from a first color to a second color upon exposure to an environment comprising an oxidizing agent. The composite articles can be flame retardant and may provide sound reduction as well.

  • Publication number: 20220266583
    Abstract: In-line systems and in-line methods of producing lightweight reinforcing thermoplastic composite panels are described. The in-line systems and in-line method can be used to produce composite panels with smoother surfaces and enhanced properties in an automated manner. The produced composite panels can include a decorative layer that can provide an overall smoother panel surface compared to a composite panel lacking a decorative layer.
