Rapid repair of rubber band scratches There are two repair methods depending on the damage situation, which are cold-vulcanized repair with repair strips and repair with rubber vulcanization repair agent. These two methods are suitable for different damages, and the appropriate repair method should be selected according to the damage.
Repair with a repair strip is suitable for long-distance tearing of the rubber belt and shallow damage surface. This repair method is to apply a repair strip on the damaged surface to avoid further tearing of the wound. During the operation of the rubber belt, it is inevitable that the material will be scraped and damaged. If it is not repaired in time, it is prone to continue to expand the damaged area, and the joint of the conveyor belt is broken. Therefore, in the event of damage, it is necessary to repair the patch in time.
Rubber belt broken and scratched - quick repair method of repair strip:
1. Draw a marking line around the damaged part, and the marking line should be wider than the damaged part by about 2-3 cm. The size of the repair strip can be as long as it matches the area of ​​the area marked by the mark line.
2. When grinding, it is best to use a high-power low-speed angle grinder with tungsten steel grinding disc to polish the marked part. At the same time, it must be noted that the grinding depth is higher than the thickness of the repairing strip, which can prevent the repairing strip from being scratched by the cleaner.
3. In order to make the repair strip and the damaged part truly seamlessly bond, it is necessary to use the cleaning agent SK353 to deeply clean and dry the damaged surface, which can clean the oil surface and other stains on the rubber surface, thereby enhancing Bond strength.
4. While waiting for the cleaning agent to dry, the cold vulcanization adhesive SK313 and the hardener UT-R40 may be mixed in proportion. Then, apply the mixed liquid evenly on the blue CN layer of the damaged part and the repaired strip, and dry it until it is not sticky.
5. When bonding the repairing strip, compact it with a compacting roller to avoid residual air between the bonding surface and the repairing surface.
6. After the repair strip is bonded to the repaired surface, the joint of the repair strip and the conveyor belt is painted with a mixed liquid of cold vulcanized adhesive SK313 and hardener UT-R40, so that the CN layer at the edge of the repair strip is naturally vulcanized.
The rubber vulcanizing repairing agent is suitable for the partial damage of the surface of the conveyor belt, the filling of the longitudinal tearing portion of the conveyor belt or the V-type sealing of the drum rubber. Rubber conveyor belt vulcanization repair agent SK358 is generally used for rubber layering belt, steel wire conveyor belt, fiber belt and rubber pipe repair. Not only the repair speed is fast, the repair strength is high, and it is glued after compounding. It does not flow, and can be repaired at any angle.
Rubber belt broken and scratched - rubber vulcanized repair agent repair method:
1. Place the conveyor belt to be repaired in a horizontal position.
2. The belt to be repaired is rounded and polished (it is recommended to use tungsten steel grinding disc or wire brush), and the surface after grinding is cleaned.
3. Mix the AB components and mix them evenly with a stir bar (approximately 2 minutes).
4. Apply a proper amount of rubber repair agent and then smooth it with a scraper. Wait for a few hours, after the surface is hardened, you can start using it.
Intermec Tips: The rubber patch after mixing should be used as soon as possible and condensed.
Float Level Gauge
Float level gauge is a liquid level measuring instrument which works based on the principle of constant buoyancy in buoyancy (Archimedes theorem).In the gravity field, the vertical upward force on the object in the fluid due to the density difference with the surrounding fluid is buoyancy.
In a liquid, an object whose overall density is lower than the liquid density will eventually float on the liquid surface. This object can be called a float. Under constant conditions, the buoyancy of the float is constant (constant buoyancy).
When the float is subjected to an upward force less than its own weight or a downward force less than the weight of the liquid equivalent to its own volume, the characteristic that the float will eventually float on the liquid surface will not be changed.
In the steady state, the buoyancy of the float is constant.
When the position of the liquid surface changes vertically, the vertical position of the float will change synchronously with the position of the liquid surface under the action of constant buoyancy.
The float level gauge is a device that displays the vertical position of the float in the form that people can read directly through various mechanical, electromagnetic, optical and other physical means.
