Conveyor belt adhesion factors
- Dec 06, 2016 -

Because of the conveyor belt in the running process will be affected by multiple factors and deviation phenomenon occurs, to ensure that the life of the interface, interfaces will not be torn apart when the belt deviation can be taken (a) shown solutions. According to the running direction of the belt will be made/convex 0-.

Bench production interface steps key cutting. After calculation, measurement, dashes, you can remove the extra layers of rubber and cloth. When you do, the knife the size of the force, underlined the depth must be strictly controlled. If too deep, it will hurt and retain some of the fabric layer, resulting in the rupture in the future; otherwise it is difficult to remove the excess layers of rubber and cloth.

Therefore, this bonding process is the key technology required by a surgeon experienced in person or to direct. Joint face grinding bench tore after the beginning, amendments to the discrepancies between the parts, and should conduct joint grinding work. The purpose of polishing is to layer adhesion of rubber cut and sanded in order to receive increased the roughness of the fabric layer, increase the bonding area,

High adhesion strength of the effect. Practice shows that under certain conditions, adhesive strength will be increased with increasing roughness.

From a micro perspective, if the bonding surface roughness is too large, concave phenomenon may result joint face poor contact form defects, bring down the adhesive strength. Particularly for illiquid adhesives, more significant. Therefore, grinding as well as rubber residue on the fabric layer, layers hair, can't grind fabric layer, otherwise affect the bonding effect. Meanwhile, belt might formed joint local fracture risk.

In addition, to keep the adhesive surfaces clean to prevent contaminated before bonding. Adhesives adhesive selection and sizing for drums, mixed with the curing agent mix are expected after the paste. Experience to be, used for bonding adhesive for conveyor belt connector which is rare as well. Rubber thickness diagrams and shear strength due to the thin coating is not easy to generate flow and creep, bubbles and defects less likely, stress on the interface will also be smaller. Therefore, to improve the bonding interface is useful. But it is easy to form thin adhesive layer for lack, coating is not continuous, and can also reduce the adhesive strength. So, apply adhesive, should promise not to lack of context, coating thickness as thin as possible as well.

Determining when an interface part of the bonding time lap, will directly affect the bonding effect. Required is applied the adhesive does not stick to hands in lap, too early or too late can cause bonding quality decreases. In the summer, the joint coated 1 glue drying time after not too long, and adhesives contain fast solvent evaporation, formed a short curing process. Therefore, in order to take the time to complete the operation. Low winter temperatures, the slow solvent in the adhesive coating, drying time may be appropriate to extend, if necessary, auxiliary heating to evaporate, in order to speed up the work progress. Overlapped operation when the accurate joints overlapped, be sure that both ends of the belt on the same straight line away from the Center, and each step well, avoid repeatedly opening due to dislocation, sticky. Lap joints was made, starting from the center line with a hammer, in turn knocking on both sides. Best with two flat steel plates between the clamp and bolt, after curing of the adhesive and then releasing, so bond is better.
