About the wet day is not sticky phenomenon of the conveyor belt

Apr 27, 2019

When purchasing the conveyor belt, it is necessary to effectively distinguish whether the conveyor belt is easily scratched, thick and so on. The high-quality conveyor belt can withstand more loads, and the transportation angle will be improved due to changes in the object during use, thereby ensuring the safety of the material. The inferior conveyor belt has a fixed load-bearing capacity. In the process of transportation, it is easy to cause the conveyor to stagnate due to insufficient thickness or insufficient quality, and even the cargo may fall off.

All conveyor belts must be connected in a ring shape to be used, so the quality of the conveyor belt joints directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and smoothly. Common methods for conveyor belt joints include mechanical joints, cold bonded joints, and hot vulcanized joints.

When the summer comes, the conveyor belt will face a new round of problems. Generally, in the summer when the conveyor belt is bonded, especially after the rain, a layer of white water vapor, that is, white mist, often appears on the surface of the rubber layer after the glue is dried, and the joint is often sticky when the glue is glued. Can not live, the formation of "wet days are not sticky" phenomenon.

This is because after the rain in summer, the humidity in the air is relatively large, and the solvent in the adhesive will take a large amount of heat from the surface of the rubber layer during the volatilization process, and the water vapor in the air condenses on the surface to form a white mist.

The water-based interface formed by the white mist is incompatible with the oily interface formed by the adhesive, so that various chemical forces formed between the two interfaces are small, and therefore, the bonded joint has no strength and the bonding fails. To solve such problems, the baking method should be used to remove the surface water mist by heating, and the glue layer can be bonded until it is dry and does not stick to the hand and has a sticky feeling.
