What Is a Flame Retardant Conveyor Belt?

Apr. 25, 2020

Fire-retardant conveyor belt, also known as a whole-core flame-retardant conveyor belt, is made of integral belt core impregnated with polyvinyl chloride impregnated paste and plasticized or vulcanized. It has high strength, large capacity, and transportation. Balance and other characteristics, at the same time, the product has good flame retardant, antistatic, impact resistance, wear resistance, corrosion resistance, and other properties.

A flame retardant conveyor belt is mainly used for underground transportation in coal mines, but also for material transportation in metallurgy and chemical industries. The whole core flame retardant conveyor belt can be divided into PVC type and PVG type.

The PVC type upper and lower covering layers are PVC cover glue, single side glue ≥0.8mm, PVG type upper and lower covering layers are both nitrile rubber and PVC, and the single side thickness is 1.5mm-4.5mm. PVC conveyor belt transportation inclination angle <16o, PVG conveyor belt transportation inclination angle <20o, can be used for coal mine underground and underground transportation.

Joint performance

According to the strength of the belt body and the structure of the belt core, the mechanical buckle connection is adopted, and the strength of the joint can reach 60-80% of the rated tensile strength of the belt body. Adhesive bonding head, the joint strength can reach 90% of the rated tensile strength of the belt. Various types of joints can meet the different needs of customers and ensure the safe and efficient operation of the conveyor system. Recommendations for choosing heavy-duty PVG conveyor belts instead of steel cord conveyor belts: With the rapid development of the coal industry, the strength of tapes used for coal transportation in underground roadways is getting higher and higher. Baite proposes to you to choose a heavy-duty PVG conveyor belt instead of a steel cord conveyor belt. Compared with traditional steel cord conveyor belt, heavy-duty PVG conveyor belt has the following characteristics:

1. The belt body is light, and the heavy-duty PVG conveyor belt is much lighter than the steel core belt of the same level, and the power consumption is also low. This advantage is very important for longer transmission systems. Therefore, it can allow the selection of a smaller power drive and can save energy for a long time.

2. The heavy-duty PVG conveyor belt has good flexibility and the belt body is thin. The conveyor can use a roller with a smaller diameter.

3. The heavy-duty PVG conveyor belt has high weft strength, (the MT668-1997 standard does not limit the weft strength), and the longitudinal tear resistance is high.

4. The joint method is flexible and fast, you can use the buckle connection method, and can also use the glue connection method. The strength of the joint is high, and the rated tensile strength of the original tape can generally be maintained at 65-90%, which is convenient for replacement and repair.

5. The heavy-duty PVG conveyor belt cover rubber has good wear resistance, high tear strength, excellent flame retardant, and antistatic safety performance, and the thickness and shape of the cover rubber can be arbitrarily selected.

6. The one-time purchase cost of the PVG conveyor belt is lower than that of the wire rope core conveyor belt, which is conducive to capital turnover. Variety structure flame retardant conveyor belt consists of covering rubber, belt core, and edge rubber. Among them, the belt core is made of cotton, hard cotton interwoven, nylon, polyester and nylon, and polyester interweaved canvas, and its adhesive layer has self-extinguishing, flame retardant, and static conductive properties.

Flame retardant conveyor belt use: This product is mainly suitable for underground transportation in coal mines, and can also be used for material transportation in metallurgy and chemical industries. The whole core flame retardant conveyor belt can be divided into PVC type and PVG type. The PVC type upper and lower covering layers are PVC cover glue, single side glue ≥0.8mm, PVG type upper and lower covering layers are both nitrile rubber and PVC, and the single side thickness is 1.5mm-4.5mm. PVC conveyor belt transportation inclination angle <16o, PVG conveyor belt transportation inclination angle <20o, can be used for coal mine underground and underground transportation.
