Product Description

Product Introduction

The flame retardant performance of conveyor belts: Currently, the main formula used by conveyor belt manufacturers is flame retardants, and the selection of flame retardants mainly focuses on the following categories:

Inhibitory Effect: Suppresses the occurrence of oxidation reactions, achieving the effect of spontaneous combustion.

Endothermic Reaction: Compound releases crystalline water or dehydrates when heated, suppressing temperature rise.

Covering Effect: Stable covering layer or foam material is generated under high temperature, and the covering surface plays the role of heat insulation and air isolation.

Dilution Effect: Generates a large amount of non combustible gas when heated, and dilutes the combustible gas to a concentration range that is non combustible.

Transfer Effect: Changes the mode of thermal decomposition of polymer materials and suppresses the generation of combustible gases.

Synergistic Effect: The combination of synergistic flame retardants has little or no significant effect when used alone.

From the above, it can be seen that flame retardants have a certain cooling effect on high temperature resistance, and improving them to a certain extent has no effect. However, using them together can greatly improve the flame retardant effect.

The Function of Flame Retardants

✔
Isolate or dilute combustible gases: Minimizes the exposure of critical belt components to reactive fuels.
✔
Cooling suppression: Achieves the high temperature resistance of the rubber conveyor belt to the ignition level. The design of rubber conveyor belt formula must be adjusted according to the on-site working conditions. The conveyor belt has passed flame retardant testing and electrostatic testing, and has obtained a certificate of conformity, coal safety mark, and customer recognition.

Product Features

This product uses integral core as the skeleton material, and is made by impregnating and coating PVC material with excellent anti-static, flame retardant and other properties, and then plasticizing it.

The maximum service life of the belt body is determined by the following factors:

★
(1) A dense core woven from warp and weft filaments and covered cotton;
★
(2) Immersing with specially formulated PVC material achieves extremely high bonding strength between the core and the cover adhesive;
★
(3) Specially formulated cover adhesive; so as to make the belt resistant to impact, tear, and wear.

Mechanical properties:

Flame retardant conveyor belts have excellent mechanical properties and can provide users with the longest service life and economical installation and use.

Frequently Asked Questions

Q: How do flame retardants protect conveyor belts?

A: Flame retardants protect conveyor belts through various mechanisms including inhibitory effects to suppress oxidation, endothermic reactions that lower temperature, covering effects for heat and air insulation, dilution of combustible gases, and transferring thermal decomposition modes.

Q: Why is a synergistic combination of flame retardants used?

A: While individual flame retardants may have minimal effects on their own, combining synergistic flame retardants works together to significantly enhance the overall cooling and flame retardant performance.

Q: What determines the service life of these conveyor belts?

A: The service life is determined by the dense woven core of warp and weft filaments, high-strength bonding from specialized PVC impregnation, and a robust cover adhesive formulated for impact, tear, and wear resistance.

Q: What skeleton material is utilized in the conveyor belt construction?

A: The conveyor belt uses an integral core skeleton that is thoroughly impregnated and coated with a specially formulated, anti-static, and flame-retardant PVC material.

Q: Have these flame retardant conveyor belts received standard industry certifications?

A: Yes, these belts have successfully passed both flame retardant and electrostatic testing, and have officially obtained conformity certificates and the coal safety mark.
