Hot vulcanization process of belt vulcanizer

Hot vulcanization process of belt vulcanizer

(1) Draw a center line on both sides of the belt belt body of the belt vulcanizing machine, and draw a cutting line according to the angle size. Based on the cutting line, draw out each processing line, cut the cover rubber layer with a knife at 45 °, and the depth should be guaranteed to reach the steel wire layer.
(2) After the step is processed, the steel wire rope is stripped with a cutter, and then the steel wire is polished with an L1202 angle grinder and a tungsten steel grinding disc.
(3) The steel wire rope and the steps are deeply cleaned with a cleaning agent. After cleaning, the hot vulcanized glue is applied and fully dried, and the hot vulcanized glue is applied again.
(4) Lay the clamping beam, hydraulic bag, heat insulation board and heating board of the lower layer vulcanizing machine. Afterwards, lay the lower layer of unvulcanized top rubber and unvulcanized core rubber, and according to the actual size, determine the position of the joints on both sides and fix them.
(5) Route the wire rope from the center to both sides. After the completion, confirm again that the center lines of the belts on both sides are consistent. Lay the upper layer of unvulcanized core rubber, unvulcanized surface rubber, upper layer heating plate, heat insulation plate, clamping beam, horns on both sides of the conveyor belt, and tighten the clamping bolts.
(6) Connect the water pressure pipe and power cord. After the preparatory work is continued, after the water pressure rises to the specified value, the power is turned on for vulcanization.
The factors affecting thermal vulcanization are:
(1) Temperature: 145 degrees-149 degrees
(2) Water pressure: local vulcanization control 0.8Mpa, belt transfer control 1.2Mpa
(3) Time: curing time is 30-45 minutes, cooling time is 1--2 hours
(4) Adhesives and glue: Adhesives include surface glue, core glue, embedded glue,
Be sure to pay attention to three parameters during the vulcanization process of the belt vulcanizer. The pressure of the hand pump is 1-2.1 MPa, the vulcanization temperature is 14 degrees to 149 degrees, and the normal vulcanization time is 40 to 45 minutes (excluding the preheating time).
