Cause Analysis and Solution of Holographic Bubbles in Crown of All-steel Truck and Bus Radial Tire
The causes of holographic bubbles in the crown of all-steel truck and bus radial tire were analyzed and the corresponding solutions were proposed.The holographic bubbles in the crown of finished tires were generated between the belt layers and between the tread and belt layers,mainly due to the viscosity variation of the semi-finished product.An unreasonable rolling trajectory could exacerbate this phenomenon.By adjusting the viscosity of the compounds and optimizing the structure and pressing trajectory of the building equipment,such problems could be basically solved.
