传送带不可避免地发生在应用的过程中各种各样的损伤,如材料处理与各种条混合的过程中边工具,随时可能导致纵向掑裂纹嵌入到传送带上。(特别容易发生在管状输送带和钢输送带上)或使用机械胶带口脱落、托辊损坏、钢丝绳芯外露、进料挡板损坏等，导致输送带跑脱，可引起输送带纵向撕裂。橡胶修补比硫化修补更容易修复上述缺陷，速度更快，更经济。橡胶修补剂是一种预聚碱类化合物，在室温下为双组分液体。按比例混合后自硫化成聚胺酯橡胶，在室温下固化成型。与输送带、金属本体结合良好，具有高弹性、高耐磨性、高韧性。
Conveyor belts inevitably suffer from various kinds of damage in the process of application, such as material handling and various mixing tools, which may lead to longitudinal pinching cracks embedded in the conveyor belt at any time. (especially easy to occur on tubular conveyor belts and steel conveyor belts) or the use of mechanical belt outlet fall off, roller damage, steel wire core exposure, feed baffle damage, etc., leading to belt run off, can cause longitudinal tear of conveyor belts. Rubber repair is easier to repair these defects than vulcanization repair, faster and more economical. Rubber repair agent is a prepolymer alkali compound, which is a two-component liquid at room temperature. Polyurethane rubber was cured at room temperature after mixing proportionally. It has good combination with conveyor belt and metal body, high elasticity, high wear resistance and high toughness.
修复过程分为三个步骤:
The repair process is divided into three steps:
表面处理。表面涂覆的目的是使修复剂与输送带骨架更好地粘结。成功修复的关键是将破口磨成60-90度的槽，并清洗表面。操作时应根据损坏情况切成不同的槽。好是用砂轮打磨，用清洗液(如丙酮)清洗。
Surface treatment. The purpose of surface coating is to make the repairing agent bond better with the conveyor belt skeleton. The key to successful repair is to grind the break into 60-90 degree grooves and clean the surface. In operation, different grooves should be cut according to the damage. It is best to grind with a grinding wheel and clean with a cleaning solution (such as acetone).
胶水和修复。选择液体形式的修复剂，将树脂与固化剂按比例混合，搅拌均匀后涂于破损口。一般来说，固化时间从几分钟到十分钟以上。修复工作必须在固化前完成。凹槽要大一些，以便修复剂能粘住未损坏的覆盖胶。
Glue and repair. Choose liquid repair agent, mix resin and curing agent in proportion, mix evenly and then coat the damaged surface. Generally speaking, the curing time is from a few minutes to more than ten minutes. Repair work must be completed before curing. The groove should be larger so that the repairing agent can adhere to the undamaged covering glue.
养护养生。该修复剂在坡口自硫化，以获得其物理化学性质和与基体的粘结效果。一般在室温下数小时数天，初数小时进行基础养护，可达到70%-80%的全固化度，24小时可达到90%。当环境温度升高时，固化时间明显缩短。因此，冬季室外施工时，有必要增加保温或保温养护措施。
Maintain health. The repairing agent is self-vulcanized at the groove to obtain its physicochemical properties and bonding effect with the matrix. Usually at room temperature for several hours to several days, the initial hours of basic maintenance, can reach 70% - 80% of the total curing degree, 24 hours a day can reach 90%. When the ambient temperature rises, the curing time is obviously shortened. Therefore, in winter outdoor construction, it is necessary to add thermal insulation or maintenance measures.
输送带连接和修理可用于剥皮机、开孔机、封边机、磨床、烘培机等机械化、自动化的工具，国内生产。随着纳米技术的应用，陶瓷mm-合成橡胶95被发现可以立即修复受损的传送带;Mm-ss钢陶瓷可修复机架、轧辊等部位的裂纹。
Conveyor belt connection and repair can be used for peeling machine, hole opener, edge sealing machine, grinder, dryer and other mechanized and automated tools, domestic production. With the application of nanotechnology, ceramic mm-synthetic rubber 95 was found to be able to repair damaged conveyor belts immediately, and Mm-ss steel ceramics could repair cracks in racks, rolls and other parts.
