How to repair the Teflon conveyor belt under special conditions?

Let us learn How to repair the Teflon conveyor belt under special conditions?

The preferred construction temperature is 15-30 ° C, and the humidity is less than 85%. If the temperature is too low or the humidity is too high and the dust is more, it is necessary to take the necessary measures.

(1) The ambient temperature is low (less than 10 ° C), it is recommended to use a hot air gun or iodine tungsten lamp to heat. The heating fixture should not be too close to the repair surface to prevent damage to the repair surface. Moderate heating can speed up the curing process, shorten the repair time, facilitate the production as soon as possible, and also contribute to the bonding strength.

(2) It is not advisable to apply in a rainy day and a dusty environment. If it is really necessary to construct, it is necessary to adopt methods such as shielding, closing, dust removal, heating baking, and hot air dehumidification within the scope of construction.

The main method to improve the quality of cold-adhesive repair of heat-resistant conveyor belt

To improve the quality of cold sticky repair, it is necessary to carry out scientific management. The quality management of cold-adhesive repair mainly includes cold-adhesive materials, operators, cold-bonding work environment, and cold-adhesive process.

(1) Cold-adhesive materials: Cold-adhesive materials are generally required to be stored in the dark at room temperature. If improperly handled, it is difficult to ensure the quality of cold-stick repair. Therefore, the cold-adhesive material should be strictly managed, and the remaining materials must be sealed. When using the glue, the amount should be considered to prevent the dross. Cold-adhesive materials that exceed the application period are not used, preventing danger.

(2) Operators: Operators who perform cold-stick repair must undergo technical training and have sufficient knowledge of cold-adhesive technology. They must have a scientific attitude and strictly follow the cold-stick repair process.
(3) Cold-bonding working environment: The working environment of cold-adhesive repair is necessary to ensure the quality of bonding. Humidity, temperature and cleanliness of environmental factors have an important influence on the quality of cold-stick repair. If the ambient air humidity is high, the surface of the conveyor belt after sanding will easily absorb moisture, affecting the wetting of the cold glue, and the interface damage is likely to occur after bonding. In order to ensure the quality of the cold bond, the ambient air humidity is not more than 85%. If the cold adhesive environment temperature is low, the cold adhesive fluidity is poor, and the surface temperature of the conveyor belt is also low. These factors make it difficult for the cold adhesive to wet the adhesive surface. Therefore, the temperature is generally not lower than 15 ° C when cold bonding, of course, the temperature is too high is not good, difficult to control, try not to exceed 25 ° C. The cold-bonded work site should prevent dust from flying. Because the adhesive surface should be open for a long time, if the dust in the air is large, the rubber surface will be contaminated, which will affect the quality of cold-stick repair.

(4) Cold-adhesive process: Each type of cold-adhesive material has its own specific process conditions, and it is necessary to follow the rules (product specification). It can't do whatever it wants, eager for success, only progress, and neglect quality. Strictly in accordance with the requirements of the cold bonding process is a strong guarantee to improve the quality of bonding. In short, in order to ensure the quality of cold-adhesive repair, it is necessary to strictly control the entire construction process of the cold-adhesive repair process.
