Because of its large load bearing rope conveyor and higher operating speed, is extensively used in the coal mine owners into transport. In recent years. With the increasing emphasis on national coal mine production safety, flame retardant conveyor belt also put forward higher requirements. But because technically, but off the conveyor belt wear declined. If the conveyor belt badly worn, bare wire rope. Not be repaired in time, then it can not run. Facing retirement. This would give the mine production schedule caused a great impact. Therefore, timely and rapid wear of the rope conveyor partial repair to ensure normal production of great significance.
Local wear repair method comparison:
    A local rubber vulcanization method: using a small pair of local breakage vulcanization vulcanization. Size is limited due to curing, repair, speed of only 0. 5m / h or so. This method is not suitable for long-distance fixed.
    2 rubber supplement method: using German technology, rubber supplement law, its biggest advantage is repaired fast. After sanding cleaning treatment of the cast supplement adhesive glue, paste, rubber, you can boot operation. The disadvantage is: usually run 60-90d, the rubber will come off. The bigger question is, if the conveyor belt is running in a humid environment, moisture will accumulate in the gap among the adhesive surface, rust rope. It will rust falling off the rope. And even cause sudden rupture the entire belt. In addition, in such cases the cost is higher.
    3 rubber patch glue repair coverage law: domestic and foreign production are two-component polyurethane adhesive rubber patch glue. After the two back together when using Stir fill to the surface to be repaired after a certain period of time to become cured elastomers like rubber. Curing time is usually 0. 5-6 h, and the environment related to the curing temperature. Colloid and the belt surface after curing has a very good adhesive properties, the experimental data show that the test chamber can reach 6kn / m (180 ° peel strength). Therefore, the combination of patching and sealing surfaces well, the situation does not appear to enter the combination of surface moisture and rust rope. More favorable is quite excellent wear resistance, abrasion value Akron 4-6 times lower than the rubber. Conveyor and superior wear resistance is localized wear repair key requirements. In summary said, this method is the most effective way to repair the rope conveyor local wear.
    By contrast the three repair methods and repair practices, we believe gum rubber patch repair method is best in coverage, but also effectively prevent the conveyor belt due to the wear and tear is not covered and sealed to form rust, caused by broken belt accident. To extend its service life and must be repaired. Finally, we welcome the procurement Qingdao Double Tiger conveyor belt conveyor belt production of various types of high quality products.
