Basic knowledge about resistance to burning conveyor belts

Resistance to Burning Conveyor Belt Introduction Burning Conveyor Belt Main Structure:
It consists of a high-temperature burnable layer, a transition layer, an organic heat insulation layer, a strong layer, and a heat-resistant layer.
characteristic:
Covering the rubber under high temperature produces a microporous carbonized layer, which is resistant to burning and can prevent heat from further transmitting to the belt and reduce the internal strength of the tape. The carbonized layer generates irregular fine cracks during the operation of the belt body and uses the belt body for cooling.
The use of inorganic materials with a diameter structure as a skeleton material for burning-resistant conveyor belts. The use of this skeleton material solves the difficulty of high-temperature carbonization, nylon, and polyester canvas shrinkage deformation of conventionally used cotton canvas, and has a small loss of strength at high temperatures. Does not shrink the deformation characteristics.
The unique adhesive formulation design ensures that the adhesive strength between the rubber and the frame material is much higher than that of the ordinary heat-resistant tape, and the inter-layer adhesive strength at the high temperature is ≥ 3N/mm.
Material temperature 200-600°C, instantaneous 800°C.
The latest types of caustic conveyor belt: Metal core conveyor belt core is the overall spiral core of the metal spiral network, resistant to burning, high temperature, flame retardant, puncture resistance, tear resistance, low elongation, high adhesive strength between layers , Groovability, vulcanized joint efficiency 100%, joint operation time is short and easy. Among them, the temperature of the metal mesh core heat-resistant conveyor belt is 150°C-200°C; the temperature of the metal mesh core burnable conveyor belt is 200°C-800°C; the metal mesh core conveyor belt has good use under different temperatures. performance.

The heat-resistant conveyor belt is specially designed for conveying materials not exceeding 800°C, and the surface temperature does not exceed 220°C when conveying high-temperature materials. The heat-resistant and high-temperature conveyor belts are further divided into ordinary heat-resistant and high-temperature conveyor belts and strong heat-resistant and heat-resistant conveyor belts. The two are mainly based on the core strength layer of the conveyor belt. The service life of heat-resistant and heat-resistant conveyor belts is affected by many factors. Its storage conditions and the maintenance measures in use all affect its life.

When heat-resistant conveyors are stored, the following guidelines should be observed:

1, storage warehouse temperature, humidity should be suitable, the general requirements of the temperature between 18 ~ 40 °C, relative humidity between 50 ~ 80.

2. The heat-resisting and high-temperature conveyor belts should be stored in rolls when they are stored, and they cannot be stored in a folded state. During storage, they should be turned periodically according to the season.

3, store direct sunlight, avoid contact with acids and alkalis, organic solvents and other substances, a certain distance away from the power generation device, because the power generation device will produce ozone when working, will produce corrosion of the conveyor belt, so that the heat-resistant high temperature conveyor belt aging .

Routine maintenance should also be carried out, mainly on the daily surface cleaning of heat-resistant and heat-resistant conveyor belts, regular inspection of conveyors and conveyor belts, and adjustment of the conveyor belt speed according to the nature of materials during transportation.
