Repair strips play a role in belt maintenance, such as bonding with the belt, protecting damaged areas, completing the belt structure, and enhancing belt strength. Belt care adhesive is very important, but the role of repair strips cannot be underestimated in belt maintenance.
Many customers used cut old belts to repair the adhesive layer by layer, and through deep polishing of the belts, the adhesive parts were made as thin as possible. This repair method can achieve a certain adhesive strength, and the strength of the repair materials is basically the same. It can still handle production work with low requirements. The disadvantage is that the repair area will have a larger thickness, usually more than 1.5 times the normal thickness of the belt, which is easily scratched by the cleaner. As the thickness of the belt increases, the bending performance of the belt will relatively decrease, and the stress during the operation of the belt is more likely to be concentrated, Ultimately causing secondary damage. It is difficult to have a satisfactory service life when using old belts for maintenance and repair.
Nowadays, professional repair strips are used for repairing and pasting belts. Repair strips, also known as rubber strips, rubber strips, or trimming strips, are mainly used for repairing rubber belts. The main body of the repair strip is wear-resistant rubber, which usually has good wear resistance, water and oil resistance, acid and alkali chemical resistance, aging resistance and other properties. It can always maintain good flexibility and strength in harsh working environments of the belt.
Many repair strips have a rubber layer of different colors on the back, which is called a semi vulcanized layer. The semi vulcanized layer is an important part of cold vulcanized belt repair technology. The semi vulcanized layer is bonded with cold vulcanized adhesive and undergoes vulcanization reaction, merging into one to achieve the same level of adhesive strength as hot vulcanization and similar bonding effects. Domestic manufacturers are also constantly intensifying the research and development of semi vulcanized layers, but there is still a certain gap compared to the already mature cold vulcanization technology. There are also some cases where ordinary rubber layers are replaced with a different color to confuse the eyes of the fish. It is important to pay attention when purchasing.
