托辊胶辊在使用过程中常因异物造成表面划伤或硌伤，若继续使用，会对纸张质量造成影响（造纸胶辊）。传统解决方法需更重新包胶，但操作较为繁琐。随着技术的发展，西方国家针对胶辊表面损伤问题多使用高分子复合材料，由于材料具有出色的粘着力聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 ，耐磨性能和抗拉性能，可根据胶辊不同的表面硬度，选择不同的修复材料，做到免拆卸维修。较传统方法修复费用更低、时间更短，在国内维修胶辊的过程应用中也逐步走向成熟。
In the process of using the idler cot, the surface of the cot is often scratched or damaged due to foreign matters. If it is used continuously, it will affect the paper quality (paper COT). The traditional solution needs to be repainted, but the operation is complicated. With the development of technology, polymer composite materials are often used in western countries to solve the problem of surface damage of cots. Because the materials have excellent adhesion, wear resistance and tensile properties, different repair materials can be selected according to different surface hardness of COTS to avoid disassembly and maintenance. Compared with the traditional method, the repair cost is lower and the time is shorter, and it is gradually mature in the process of domestic repair of cots
