Heat-resistant conveyor belts are mainly used in metallurgy, construction and other industries to transport high-temperature materials such as sinter, coke and cement clinker. The temperature of the material does not exceed 800 °C, and the surface temperature does not exceed 220 °C. Characteristics: EPDM rubber is used as the covering layer, mainly based on the main performance of heat-resistant belt damage and loss of conveying capacity and different heat resistance levels. The skeleton material adopts domestic special high temperature resistant canvas, and the unique formula design solves the problem of high stability due to high saturation of ethylene propylene rubber, poor adhesion and low adhesion between layers. It has the characteristics of light body, long life (about 2-4 times) and good heat resistance.
Heat-resistant conveyor belts are mainly used to transport high-temperature materials such as sintered ore, hot coke, cement clinker, and hot castings. According to the main performance of heat-resistant belt damage and loss of conveying capacity and different heat-resistance levels, respectively, using EPDM or styrene-butadiene rubber as cover rubber; high-strength and high-permeability polyester canvas or cotton canvas as strong layer, covering glue and skeleton A heat-resistant glass cloth can be additionally provided between the layers to improve the service life of the heat-resistant belt, and can be made into a ring-shaped belt according to user requirements. The heat-resistant conveyor belt is made of multi-layer rubber cotton canvas (polyester cotton cloth) or polyester canvas with high temperature resistant or heat resistant rubber. It is bonded together by high temperature vulcanization. It is suitable for conveying hot coke, cement and slag below 175 °C. And hot castings, etc.
The chemical industry divides the heat-resistant conveyor belt into T1, T2, and T3 grades, and the corresponding test temperatures are 100, 125, and 150 degrees Celsius. It has become apparent that it cannot adapt to current usage requirements. Therefore, it is necessary to have a comprehensive understanding of the skeleton material of the heat-resistant conveyor belt, the cover rubber, the compounding system and the processing technology, so as to develop a new type of service life heat-resistant transportation to meet the development needs of these industries.
