The Methods of Repairing the local wear of Teflon conveyor belt in time

Because of large load bearing capacity and high running speed,the higher flame retardant performance of teflon conveyor belt is also required. However, if the technology is not reach the quality standard, the wear resistance of the conveyor belt will decline. If the conveyor belt is seriously worn, the glass fiber will leak out. It won’t work and even be scrapped without a timely fix, which will have a bad impact on the production schedule. Therefore, it is of great significance to repair the local wear of teflon conveyor belt in time to ensure normal production.

Three methods of local wear repair

1.Rubber Patching: The biggest advantage of using of rubber patching that came from the German technology is the fast repair speed. Its downside is that the rubber usually falls off after 60-90 days. What’ more, if the conveyor belt operats in a moist environment, the water vapor will accumulate in the gap between the bonding surfaces and rust the steel wire ropes. It will rust and break the wire rope for a long time, and even cause the breakage of the whole conveyor belt . In addition, this repair method costs a lot.

2.Local Rubber Vulcanization: The partial damage place is vulcanized by the small vulcanizing device. Due to the size of the vulcanizing device, repairing speed is only about 05M/H. This method is not suitable for long-distance reparation.

Rubber Repair Adhesive Covering : The rubber repair adhesive produced at home and abroad is two-component polyurethane adhesive liquidhome and abroad. After mixing the two together, they are filled into the worn surface, and they can form an elastomer that is similar to rubber in a certain time.The time required for curing is generally 5-6h, which is related to the temperature. Laboratory data indicated that the peeling strengthcan reach 6kn/m180 degree, so the combination of repair surface and sealing is pretty good, and do not happen the situation that water vapor cracks into the binding surface and rusts wire rope. What’s more favorable is that its wear resistance is is quite excellent. And the superior wear resistance is the key requirement of the conveyor belt local wear repair. In summary, this method is the most effective way to repair the local wear of conveyor belt.

Through the comparison of three kinds of patching methods and the practice of repairing, we believe that the rubber repair adhesive covering is the most effective method. Furthermore, it can effectively prevent the corrosion of Teflon conveyor belt,which willl result in belt breakage accident.

Teflon High Temperature Cloth and its Application

Teflon high temperature cloth is a product with broad uses, which is renowned for its excellent properties, high-temperature resistance and dimensional stability.

Teflon tape storage, use and maintenance

Teflon tape should be stored in the warehouse, to avoid sun and rain. Prohibition of acid-base oil organic solvent contact, keep clean and dry, 1m away from the discovery device, room temperature between -15 ℃ ~ 40 ℃.

Teflon tape should be placed in rolls, not folded. If the storage time is too long, it should be flipped quarterly.

It is best to use cranes when loading and unloading conveyor belt, and with beam of rigging to lift up smoothly, avoid damaging the edges. Do not barbaric loading and unloading, causing loose rejection thrum.

According to the needs of use and specific conditions to reasonable choose Teflon tape types and specifications.

Different varieties, specifications, strength, the number of layers of tapes can’t be connected (with group) together.

It is better to use heat vulcanized adhesive for conveyor belt connector to improve reliability, maintain high effective strength.

Conveyor roller diameter and conveyor belt minimum pulley diameter should comply with the relevant provisions.

Do not make the tape snake or creep, to keep the roller, vertical roller flexible, tension should be moderate.

If the Conveyor equipped with baffle and cleaning device, wear and tear on the tape should be avoided.

Cleanliness is the basic condition for good tape operation. Other substances will affect the tape off center, tension differences, and even rupture.

If any damage found in the use of Teflon tape, we should promptly find the cause and repair, to avoid the emergence of any adverse consequences.

How to store Teflon adhesive tape

Teflon adhesive tape is smooth, has good anti-sticking, chemical resistance, high temperature and high insulation, it is widely used in packaging, thermoplastic, composite, sealing heat and electrical and electronic industry. However, it is often appear this kind of circumstance during use: Teflon adhesive tape can not be used after bought back and store for few months. The problem is mainly due to storage and protection. So what do you need to pay attention to in storage and protection?

Storage Teflon adhesive tape should be packaged in a good package, and then sealed with plastic film, Seal is to avoid the sun, rain, and also to prevent contact with chemical corrosion solvents, but also should keep the warehouse dry and fire. Same type and thickness of Teflon adhesive tape should be placed together, and indicate the storage time with the label. If you want to store unspent Teflon adhesive tape, the tape should not only with plastic film packaging, but also with the label indicate the use of time and storage time. When using tape, be sure to follow the storage time to use. In the tape storage time, we need to regularly open the tape packaging, check the tape color and viscosity,If finding problems, one should timely handle with.

Do not use exceed the shelf life of the PTFE Teflon adhesive tape

Teflon adhesive tape with a shelf life, the viscosity and strength of the Teflon tape exceed the shelf life is poor than the tape in shelf life.

The composition of Teflon adhesive tape: Inside is glass fiber cloth, and then coated with Teflon, and finally stick glue on the Teflon cloth, adhesive composition is the high-temperature silicone.
The problem of Teflon adhesive tape is affected by the sticky after shelf life: Over time, the viscosity of high-temperature silicone in Teflon tape will decline due to time, Based on the results of the aging test, we recommend that manufacturers with high viscosity requirements should use the Teflon tapes within 1 year after purchase. 3 to 5 months of viscosity can be guaranteed, then the viscosity will slowly decline, more than one year after the viscosity will be greatly reduced.

Another component of Teflon adhesive tape is Teflon coated fiber glass cloth. Because of long-term contact with air, so Teflon cloth by the corrosion of air and gradually be oxidized, thus affecting the strength. Originally high strength Teflon tape, because a long time in contact with air, it can easily be torn off when tearing. Therefore, we suggest customers do not to buy too may Teflon tapes, generally not more than 6 months dosage.

Teflon tape is a consumable, after used a period of time should be replaced in a timely manner to avoid has an impact on production because of environmental impact, do not to use the almost over the shelf life tapes.

PTFE Teflon adhesive tape storage and use of maintenance
