Influence of winter on belt bonding process
Winter belt bonding
The impact of winter on the belt bonding process: As the weather turns cold, the damage of the conveyor belt enters the peak period, and the conveyor belt joint is the most vulnerable place of the conveyor belt, then what impact will the winter weather have on the belt bonding process?
First, the impact of winter on the conveyor belt analysis
With the coming of winter, the temperature will get lower and lower, and the conveyor belt rubber will harden at such a temperature, so that the flexibility of the conveyor belt will become weaker and easier to break and damage. It can be said that the conveyor belt damage has entered a high period.
Second, the impact of winter on the belt bonding process?
The low temperature in winter has little impact on the vulcanized conveyor belt joint process, and mainly has a great impact on the cold adhesive belt bonding process. We all know that the cold adhesive belt bonding adopts the method of brushing conveyor belt adhesive at room temperature for bonding. The principle of this bonding method is that the conveyor belt adhesive penetrates into the conveyor belt line layer and the rubber, forming a bonding layer on the surface. The bonding between the conveyor belts is actually the bonding of the adhesives on both sides, so as to achieve a strong bond between the conveyor belts. Conveyor belt adhesive at low temperature conditions, will become sticky, not easy to penetrate into the rubber and wire layer, so the belt bonding effect will be reduced, which is why it is not recommended to use cold adhesive belt bonding process in winter.
Third, the use of cold adhesive belt joint remedial measures and suggestions in winter.
1. The vulcanized joint method is recommended when the ambient temperature is lower than 0 ° C.
2. Warm the conveyor belt adhesive with hot water before bonding, so that the conveyor belt adhesive is easy to flow.
3. Use tungsten iodide lamp to bake and warm the surface of the belt adhesive joint.
4. After brushing the adhesive, it should also be heated.
5. Extend the curing time after the belt bonding is completed, and take heating measures around it.
Before the arrival of winter, it is necessary to check the conveyor belt before the temperature becomes low, and glue the damaged parts in advance to prevent it from happening.
