The use of polymer composite materials to repair and control the oil leakage of the right-angle planetary reducer. The polymer composite materials are based on polymer, metal or ceramic ultrafine powder, fibers, etc., and are compounded under the action of curing agents and curing accelerators. Made of materials.

　　Various materials complement each other in performance and produce a synergistic effect, so that the comprehensive performance of the composite material is better than that of the original composition material.It has strong adhesion, mechanical properties, and chemical resistance.

　　Therefore, it is widely used in the repair of mechanical wear, scratches, pits, cracks, leakage, casting sand holes, etc. of metal equipment, as well as the chemical anti-corrosion protection and repair of various chemical storage tanks, reaction tanks, and pipelines.

　　For the leakage of the static sealing point of the right-angle planetary reducer, the leakage can be treated on-site without disassembly. The polymer composite material can be used to treat the leakage externally, which saves time and effort, and the effect is immediate.

　　Its products have superior adhesion, oil resistance and 350% elongation, overcome the impact of the vibration of the reducer, and have well solved the problems that have not been solved for many years.

　　If the static sealing point of the right-angle planetary reducer leaks oil during operation, the oil surface emergency repair agent of surface engineering technology can be used to stick it to eliminate the oil leakage.
