Description

Technical Field

[0002] The dimensional accuracy of the plastic liner has an important impact on the service performance of the Type IV hydrogen storage bottle. Poor wall thickness uniformity will directly lead to deformation of the liner and reduced straightness, which will in turn lead to poor winding process, cracking of the hydrogen storage bottle, and reduced pressure resistance. As an important liner molding method, rotational molding is challenging in controlling the uniformity of the liner wall thickness. The core reason is the lack of a mechanism for the influence of the rotational molding process on the dimensional accuracy of the liner, and the industry has rarely studied the details of the influence of process factors on wall thickness.

[0003] The plastic liner is an important component that distinguishes Type IV hydrogen storage bottles from Type III hydrogen storage bottles. It plays an important role in storing hydrogen and preventing leakage, and is used to improve the lightweight effect and fatigue resistance of hydrogen storage bottles. Type IV high-pressure hydrogen storage bottles are one of the important links to promote the development of hydrogen energy. Compared with several other types of high-pressure hydrogen storage bottles, Type IV high-pressure hydrogen storage bottles have the advantages of lightweight and hydrogen embrittlement resistance due to the use of plastic liners; however, the wall thickness of the plastic liner cannot be adjusted according to actual needs during rotational molding. Summary of the invention
