However, the rubber hose can be damaged comprehensively to different degrees due to external factors during transportation, storage, and processing and use, which may cause structural damage and loss of good usability.
The breakage problem of the rubber hose can be mainly analyzed from four aspects: the appearance, the mechanical property, the physicochemical property and the electrical property are the first one. The steel wire, which is the main structure of the rubber hose, has the guarantee function of bearing the established function of the hose, so once corrosion and fatigue problems occur, the service performance of the material is seriously influenced, and the mechanical property of the material is also reduced. The rubber hose also has the problems of embrittlement, cracking and even more serious hose burst in different degrees when the aging degradation problem occurs, thereby influencing the normal function of the material.
