【Abstract】 The sticking strength, tensile strength and shearing strength of thermosetting layer of Alu- minum and immerse resistance of type WRF8401 seal layer are determined in the laboratory. The re- sults show that the method of thermosetting pure Aluminum added to the seal layer can be effectively used to protect liquefied petroleum gas (LPG) sphere from cracking by stress etch. Experiments show that the function of protect layer is closely concerned with the construction technology and the thick- ness of the protecting layer.更多还原
