I believe everyone is familiar with belt repair strips. Before choosing, how much do you know about belt repair strips? The current belt repair strips are generally divided into two categories: reinforced and ordinary, with a much wider width of 100mm, 150mm, 220mm, 300mm, and 400mm. Seeing so many categories, don't you know which one to choose? Don't worry, you're right after reading this article.
The repair strip is divided into two types: reinforced and ordinary, used for repairing local damage, long-distance scratches, and sealing treatment of cold adhesive joints on the belt. The repair strip is made of wear-resistant rubber on the front side and a blue semi vulcanized CN layer on the back side, which forms a cold vulcanization reaction with the cold vulcanization adhesive SK313, thereby strengthening the bonding strength of the damaged surface of the belt.
1. RIT reinforced repair strip
Compared to ordinary repair strips, reinforced repair strips are more popular during the repair process, such as the well-known RIT repair strip, which is a typical representative. Due to the fact that the repair strip itself has a fabric reinforcement layer and a semi vulcanized CN layer, this type of repair strip not only has high adhesive strength, but also is more tensile and wear-resistant. In short, for better repair of damaged parts of the belt, reinforced belt repair strips are definitely a good choice.
Advantages: tensile and wear-resistant, so the repair strength of the belt is higher. If compared to hard indicators such as tensile strength, wear resistance, and strength, RIT reinforced repair strips have strong competitiveness.
Disadvantage: Thick, not every part of the belt needs to be repaired in this way, and sealing the cold adhesive joint of the belt belongs to this category.
2. RIT ordinary repair strip
The price of ordinary repair strips is slightly lower than that of reinforced ones. This type of repair strip does not have a fabric reinforcement layer and is relatively thin in thickness. There are many benefits, such as sealing the working and non working surfaces of the belt cold joint. In addition, it is also used for repairing damage to the belt body that has not been fully scratched, resulting in better adhesion. If the belt is scratched thoroughly, Inmet recommends using reinforced repair strips.
Advantages: The repair strip has good adhesion and outstanding flexibility, and can be used for local belt damage and cold adhesive joint sealing treatment.
Disadvantage: The tensile strength is not good enough.
3. RIT repair strip width selection
The width of the repair strip is mainly used in three specifications: 100mm, 150mm, and 220mm. During on-site use, the width of the repair strip should be selected appropriately based on the condition of the belt damage. In principle, it should be 50mm wider than the edge of the damaged part of the belt. A slightly wider repair strip can increase the repair strength, but remember to be too wide.
