Conveyor Belt Repair Company FAQ
Conveyor Belt Repair Tape – Definitive Guide
During the bulk material conveying of the belt, various damages may occur due to material dumping, falls. Such as longitudinal tearing, edge damage, gouged, deep punctured, and so on. For these questions, we need to evaluate whether the belt is repaired or replaced.
If the fabric conveyor 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 damages can be repaired by cold vulcanization solution.
What is Conveyor Belt Repair Tape
Conveyor belt repair tape is often called rubber repair strip or repair rectangular patch, it is made by synthetic rubber, which compounds with superior quality neoprene-based bonding layer on one side. There are two color conveyor belt repair strips, blue and green. Conveyor belt repair tape is highly tensile strength, high wear-resistant, and 60 Duro natural rubber strips designed to repair the damage of 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 the 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 surface too.
Conveyor Belt Repair Tape Features
Cold Bond Repair is easy to operate and fast installation, rapid cure time allowing for normal use of conveyor belt in as little as one hour.
Beltcare Conveyor Repair tapes have characteristics of high tensile strength, abrasion resistance, and each product is supplied with a CN bonding layer, together With TIPTOP/TRS cold vulcanized cement, this will achieve ultimate adhesion when bonded to rubber conveyor belt surfaces.
BELTCARE Rubber Repair Strips or Patches are supplied a feathered edge to allow the repair strip or patch to completely merge with the existing conveyor belt cover.
Types of Conveyor Belt Repair Tape
The conveyor belt repair patches are available in standard and reinforced types and various sizes. The Rubber repair strips of different sizes are selected to repair according to the actual damage size. Generally, it is better that the rubber repair strips are 20-30 mm wider than the belt damaged part and repair by internal embedding.
Fabric reinforced repair strips thick is about 1.4 mm more than the standard type, they are recommended to use for the repair of damage to conveyor belt ply and covers or steel cord conveyors in heavy operating conditions or applications, which require maximum tear strength and puncture resistance.
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 be consistent with the 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. If you feel slightly sticky when touching the surface, brush it again. The blue CN layer of the 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 compacting 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. If you can wait for 4-8 hours, it can achieve the best repair effect.
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 repair strip and reinforced repair strip.
Conveyor Belt Repair Tape Specifications
5 different common specifications are available in the conveyor belt repair tapes: 100mm\150mm\220mm\300mm\400mm. We need to choose the appropriate repair strip according to the actual situation of the conveyor belt.
The front side of the repair strip is made of wear-resistant rubber, and the backside is a blue semi-vulcanized CN layer, which forms a cold vulcanization reaction with the cold vulcanization adhesive TRS2002 to strengthen the bonding strength of the damaged surface of the belt.
Beltcare Solution takes the commonly used RIT conveyor belt repair strip as an example to introduce the next conveyor belt repair strip in detail.
Reinforced Repair Strip
Compared with ordinary repair strips, reinforced repair strips are more popular in the conveyor belt repair process. Take the RIT repair strip as an example, because the repair strip itself has a fabric reinforcement layer and a semi-vulcanized CN layer, this type of repair strip has a high bonding strength and is more resistant to tension and wear
If you want to have a better repair of the damaged part of the belt, the reinforced belt repair strip is definitely a good choice.
Advantages: with great resistance to tension and wear, you can get a higher repair strength for your damaged conveyor belt.
Disadvantages: thick, not every damaged part needs to be treated in this way. Just like the sealing of the cold bonding head part of the belt, it couldn’t be repaired this way.
Ordinary Repair Strip
The price of the ordinary repair strip is slightly lower than that of the reinforced type. This type of repair strip does not have a fabric reinforcement layer, so it is relatively thinner.
The ordinary repair strip has a good fit and outstanding flexibility, you can use it to treat the sealing between belt cold joint sealing face and non-face. Besides, you can also use it to repair the non-penetrating damage of the conveyor belt.
Advantages: The repair strip has a good fit and outstanding flexibility
Disadvantages: the tensile strength is not good enough.
Repair Strip Width Selection
The width of the repair strip is mostly used in the three specifications, 100mm, 150mm, and 220mm. Here are the common specifications of conveyor belt repair strips (take the commonly used RIT conveyor belt repair strips as an example)
The specifications of ordinary repair strips (without fabric reinforcement) (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 repair strip (with fabric reinforcement 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
Usually, the strip width is 20-30mm wider than the edge of the damaged part of the belt. A moderately wide repair strip can increase the strength of the repair, but it should not be too wide.
For example, the width of the damaged part of the conveyor belt is 50mm, so a repair strip with a width of about 80mm will be ok. Match with the specifications of the RIT conveyor belt repair strip above, you can choose a 100mm repair strip.
The choice of repair strips should be wide rather than narrow. If it is too narrow, the damaged part cannot be completely wrapped, it is easy to appear material leakage and increased damage part size.
Of course, too wide is also inappropriate, it is easy to cause waste of materials and directly increase the repair cost.
For example, if the damaged width of the conveyor belt is 90mm, it is better to choose a repair strip with a width of about 120mm. When using the RIT conveyor belt repair strip for operation, there are 100mm and 150mm to choose from.
However, it is not appropriate to choose a 100mm wide repair strip according to the “principle of suitable width rather than narrow repair strip”. At this time, it is necessary to choose a 150mm repair strip for repair.
During on-site operation, the length and thickness of the repair strip will also be required. When cutting the length of the repair strip, follow the same principle as the width.
For the thickness, according to whether it damages the inner fabric layer of the conveyor belt, you can choose a reinforced patch strip with a fabric reinforcement layer or an ordinary conveyor belt patch strip without a fabric reinforcement layer for operation.
