1、 Adhesive method for rubber belts
There are many bonding methods for rubber belts, among which lap bonding and shrink bonding are two commonly used methods. Lap bonding is the process of overlapping two ends together and using glue to bond them together; Reduced diameter bonding involves reducing the diameter of both ends by a certain proportion, and then using glue to bond them together.
2、 Preparation before bonding
Whether it is lap bonding or reduced diameter bonding, surface treatment is required for the rubber belt. Firstly, the surface of the rubber belt needs to be sanded to increase the adhesion of the adhesive. Then use a cleaning agent to clean the surface and remove oil and dust. Finally, ensure that the surface is dry, otherwise it will affect the quality of the bonding.
3、 Lap bonding method
- Lap the rubber belts at both ends together, with an overlap length of generally 40-50 millimeters.
- Apply glue to the overlapping area, press and glue tightly, without bubbles. The use of reduced diameter bonding method is the same.
- Leave the glued rubber belt for a period of time to dry. The drying time is generally more than 24 hours, and the specific time depends on the formula of the adhesive.
4、 Reduced diameter bonding method
- Draw two concentric circles, inner circle and outer circle, on the surface of the rubber belt at each end. The diameter ratio of each circle is generally 4:5.
- Use scissors to cut off the outer circle and keep the inner part. Wear gloves to avoid contact with hands, as there may be oil stains on the surface of the rubber belt, and the grease on the hands can affect the bonding effect.
- Apply glue to the reduced diameter area, insert the reduced diameter parts of the two rubber belts, press them tightly and glue them together, without any bubbles.
- Leave the glued rubber belt for a period of time to dry.
Overall, the bonding method for rubber belts is relatively simple, but it is necessary to ensure that the surface is dry, clean, and fully sanded, and to choose a suitable adhesive to ensure the bonding effect. Both overlapping and reducing bonding methods need to be persistently pressed and glued, waiting for the glue to dry, and not rushing to use it.
