& nbsp; & nbsp; Rubber repair agent conveyor belt repair seamless joint technology sharing

  & nbsp; & nbsp; Large conveyor belts, tires, cables, rubber rollers and other rubber products are often scrapped as a whole due to local breakage and wear. The use of rubber repair agent series products allows for quick on-site repairs. The repaired coating has characteristics such as wear resistance, corrosion resistance, high strength, high toughness, and high elasticity, making it a fast and reliable repair method.

  & nbsp; & nbsp; Repair of Rubber Repair Agent Conveyor Belt Damage

  & nbsp; & nbsp; 1. Surface treatment

  & nbsp; & nbsp; First, cut off the worn fabric or torn rubber, and use a rotating wire brush to roughen the damaged area and at least 10cm around it, forming a wool like surface. Then use a cleaning agent to thoroughly clean the entire area to be repaired.

  & nbsp; & nbsp; 2. Apply primer

  & nbsp; & nbsp; Carefully apply the rubber adhesive to the surface treated area using a hard bristled brush as a base adhesive to increase the bonding strength< br />


  & nbsp; & nbsp; 3. Repair techniques

  & nbsp; & nbsp; ① In the case of long-distance tearing, a clamping device must be installed to align the belt along the crack. For the damaged part that penetrates, seal the back with adhesive tape
  & nbsp; & nbsp; ② When the bottom glue is not sticky to the hands, prepare the rubber repair agent in proportion and make sure to mix it evenly. Use a rubber knife to apply the prepared rubber repair agent to the area to be repaired that has been coated with primer< br />
  & nbsp; & nbsp; ③ After curing at 25 ℃ for 2 hours, it becomes elastic and can resume belt operation after 12 hours. When the shutdown time is short or the temperature is below 15 ℃, it should be heated to 50-60 ℃ and kept for 3-4 hours to fully cure and resume operation.

  & nbsp; & nbsp; Rubber repair agent for seamless joint production

  & nbsp; & nbsp; 1. Make trapezoidal steps according to the thickness of the conveyor belt, and it is best to form a 45 degree angle at the overlap of each step. Generally, the overlap width is equal to the width of the belt< br />
  & nbsp; & nbsp; 2. Use a wire wheel to roughen the bonding surface, and the residual rubber on the canvas (or nylon cloth) must be polished clean before cleaning with a cleaning agent< br />
  & nbsp; & nbsp; 3. Apply a thin layer of the prepared rubber adhesive evenly on the bonding surface with a plate brush or glue knife. When the adhesive film is not sticky to the hand, apply a second layer of adhesive, let it dry to evaporate the solvent, and then apply a third layer of adhesive. Finally, when the adhesive film is not sticky to the hand, align it with the interface for bonding. After bonding, it is best to use a heavy steel plate to firmly clamp the joint or repeatedly roll it with a circular roller several times to eliminate air at the bonding site. Be careful not to move the joint back and forth after bonding< br />
  & nbsp; & nbsp; 4. After curing at room temperature for 24 hours or curing at room temperature for 2 hours, heat it to around 80 ℃ and cure for 3 hours before putting it into use.
