1The whole fabric core layer is made of cotton yarn and nylon or polyester fiber, and then woven with the weft thread in three or more layers of the whole fabric structure, and impregnated.PVCThe core paste is plasticized;

2．PVCConveyor belt cover mainly consistsPVCCover muddled covered by plasticization;PVGThe surface layer of the conveyor belt is vulcanized on the basis of the integral belt core layer and the rubber cover.

2PVC,PVGConveyor belt performance characteristics and main use:

◆ Performance characteristics

1. toolsExcellent flame retardancy, good conductivity;

2The belt body shall not be delaminated, with small elongation, impact resistance and tear resistance;

3. Light weight, high strength, good grooving

4．PVCThe conveyor belt is suitable for conveying materials under dry conditions with an inclination of 16 degrees;

PVGConveyor belt for inclination 20The transportation of wet materials with water below the degree.

◆Main purpose

PVC、PVGThe whole core flame retardant belt because of its good safety flame retardant self-extinguishing and electrostatic conductivity, suitable for coal mine flammable occasions to transport coal, such as the main roadway, work mining surface, coal bunker, coal washing plant and other coal transportation; can also be used for the requirements of flame retardant static electricity, chemical industry, metallurgy and other industries.

Three. Technical Standards

     PVC,PVGProduction execution of flame retardant beltMT914-2008"Coal mine fabric core flame retardant belt" standard.

You can also pressBS3289,BC158,AS4606standards such as the organization of production.

4 Product type and performance index

◆ Minimum recommend drum diameter

◆ Joint mode: PVCPVG whole core flame retardant conveyor belt can be mechanical joints or adhesive joints. The joint strength shall meet the following criteria:

◆ Model description: for example800S,800Indicates that the overall longitudinal tensile strength of the flame retardant belt is800N/mm,SIndicates that the flame retardant belt has flame retardant and antistatic properties.

Five. Production process
11. High strength integral belt core

My company coal mine conveyor belt with the whole core according to the national coal industry standardsMT317-2002Production, warp to the use of polyester or polyester fiber and cotton yarn blended, the weft to the force line using high strength, tensile deformation properties of nylon fiber. Improve the tape tear resistance, impact resistance, surface adhesive force, anti-wear performance and is conducive to improving the tensile strength of the joint, extending the life of the flame retardant belt body and joint.
