[0002] Vacuum coating is an important aspect of vacuum application. It is based on vacuum technology, uses physical or chemical methods, and absorbs a series of new technologies such as electron beam, molecular beam, ion beam, plasma beam, radio frequency and magnetron to provide a new process for thin film preparation for scientific research and actual production. Simply put, the method of evaporating or sputtering metals, alloys or compounds in a vacuum to solidify and deposit them on the object to be coated (called substrate, substrate or base) is called vacuum coating.

[0003] When an object is vacuum-coated, the metal or alloy evaporated in a vacuum requires a low-temperature-resistant pipe to be transported during the transportation process, and then the object is coated. However, in the existing technology, ordinary stainless steel pipes and rubber coatings are usually used to transport the evaporated metal medium. The insulation effect during the transportation process is poor, and the life of the pipe is short due to the low temperature, so the pipe needs to be replaced regularly. The low-temperature resistance and insulation effect of the conveying pipe under low-temperature conditions need to be further improved. Therefore, we need to propose an insulation device for low-temperature pipes. Utility Model Content
