Conveyor Belt Repair Tape

During the bulk material conveying of the belt, various damages may occur due to material dumping and falls. Such as longitudinal tearing, edge damage, gouges, deep punctures, and so on. For these questions, we need to evaluate whether the conveyor belt is repaired or replaced.

If the conveyor belt cover rubber wear is near the limit, the tear is more than 7 points per meter length, the horizontal puncture reaches 1/3 of the belt width, it needs to replace the damaged part with a new belt. However, most of the damage can be repaired by a cold vulcanization solution.

What is Conveyor Belt Repair Tape

It is often called a conveyor belt repair strip or rubber repair strip, or a rubber repair patch. It is made of synthetic rubber, which is compounded with a superior quality semi-vulcanized bonding layer on one side. Conveyor belt repair tape is highly wear-resistant, and natural rubber strips are designed to repair damage to conveyor belt covers.

As Conveyor belts are often exposed to heavy stress, this leads to wear and tear on the belt, surface damage, or even holes. Repair such damage with our conveyor belt repair tape for cold vulcanizing fast and efficiently. Furthermore, it can be used to repair longitudinal breaches, damaged topcoats, damaged edges of the belt, or bonding rubber to steel surfaces too.

How do you fix a ripped conveyor belt?

Your operating steps will directly affect the repair effect, please do it strictly according to the following steps:

• Grinding and Cleaning

You should calculate the grinding area first, the grinding width and thickness should conform with the rubber repair strip. Then use the Angle grinder and tungsten steel polishing plate to polish the damaged surface. Finally, sweep away the residue, clean it with a cleaning agent, and dry it.

• Mix and Glue

After mixing the cold curing adhesive and curing agent in proportion, evenly brush the mixture on the adhesive surface, wait some minutes, and test it with the back of your hand. a moment later, brush it again. The CN layer(bonding layer) of the rubber repair strip also needs to brush a layer of mixture.

• Bonding and curing

If you feel slightly sticky when touching the surface again, it’s time to bond it. Please paste the patch strips from one side and use a compacting roller to compact them from the middle to the sides, it can drain the air. Finally, brush the joint evenly on the surface with the mixture.

Everything is ok, then wait 2 hours for its natural vulcanization. At this step, you can use the conveyor belt for your projects. It is  fast and easy to operate, and doesn’t need to stop all the conveyor system

How to Choose Conveyor Belt Repair Tape?

A conveyor belt repair strip can be used for repairing local damage, long-distance belt scratches, and sealing between the cold adhesive head portion. It is generally divided into two types: standard and reinforced types.

Specifications

Different common specifications are available in the conveyor belt repair tapes: 100 mm, 150 mm, 220 mm, 300 mm, 400 mm. We need to choose the appropriate rubber repair tape according to the actual situation of the conveyor belt.

The front side of the repair patch is made of wear-resistant rubber, and the back side is a semi-vulcanized CN layer, which forms a cold vulcanization reaction with the cold vulcanization adhesive to strengthen the bonding strength of the damaged surface of the belt.

We take the commonly used rubber repair strips as an example to introduce them in detail.

Reinforced Type

Compared with standard types, reinforced repair strips contain a high-strength fabric inside. This type has a superior breaking force, which is suitable for the longitudinal tearing repair of the conveyor belt and the repair of structural damage

Their technical data is as follows: Fabric Layer Lateral Tearing Force(N/mm):89.5; Fabric Layer Longitudinal Tearing Force (N/mm):218

Anyhow, both the standard and the reinforced types feature a bonding layer

Standard Type

It is made of a synthetic rubber compound with a quality semi-vulcanized bonding layer on one side. It is highly elastic, high wear-resistant, leakproof, waterproof, and flame-retardant.  The standard type is suitable for the long-distance scratching of the conveyor belt.

Furthermore, it has a good fit and outstanding flexibility; it can be used to treat the sealing between the belt cold joint sealing face and non-face.

Importantly, with the quality CN layer, our repair patches don’t need to be polished before use and can be bonded directly.  And the bonding layer adhesive Force increases with time, while the adhesion of the inferior bonding layer doesn’t change over time, it will be better for completely repairing the conveyor belt.

Sizes Selection

The width of the conveyor belt repair tape is mostly used in the three specifications: 100mm, 150mm, and 220mm. Here are the common specifications of conveyor belt repair tapes as follows:

The specifications of the standard (thickness * width * length) are as follows:

2.2*100*10000mm; 3.2*150*10000mm; 3.2*220*10000mm; 3.4*300*10000, mm; 3.4*400*10000mm

Reinforced type (with fabric reinforced layer) (thickness * width * length) specifications are as follows:

3.6*100*10000mm; 4.6*150*10000mm; 4.6*220*10000mm; 4.8*300*10000mm; 4.8*400*10000mm

With the 20-30mm wider than the edge of the damaged part of the belt. It could make the rubber repair strip merge with the conveyor belt well in patching.

For the convenience of customers, various sizes are available, such as the following widths: 50mm, 75mm,100mm,150mm,220mm,300mm,400mm,500mm, etc. More sizes &shapes can be customized.
