1.Heat resistant conveyor belt characteristics: Heat resistance conveyor belt consists of multi-layer cotton canvas (cotton cloth) or polyester canvas covering high-temperature resistant or heat-resistant rubber, bonded through high temperature vulcanization, suitable for transporting hot coke, cement, slag and hot castings with the temperature less than 175â??. 2.Heat resistant conveyor belt application: Mainly used in industries such as metallurgy, construction, etc. For transporting sintered ore, coke, cement clinker and other high-temperature materials, the material temperature does not exceed 800â??, the belt temperature does not exceed 175â??. According to the manifestation of the heat resistant belt breakage until to lose transportation ability and the heat resistant grading, we use edpm or sbr as the covering layer rubber, and high modulus low shrinkage polyester or cotton canvas as the strong layer. It can use the heat resistant woven glass fabric between the cover rubber and the layers, so as to improve the working life of the heat resistant conveyor belt. We can make it into endless conveyor belt as per clients requirement. 3.The physical properties of heat resistant conveyor belts Physical properties of the resistance to the tropical covering Projects Type T1 T2 T3 T4 Allowable variation range Hardness Difference between after aging and before aging(irhd) +20 +20 ±20 ±20 Maximum value after aging(irhd) 85 85 85 85 Tensile strength Rate of performance change/% -25 -30 -40 -40 Minimum value after aging/mpa 12 10 5 5 Elongation at break Rate of change after aging/% -50 -50 -55 -55 Minimum value after aging/% 200 200 180 180 Note: t1--the testing temperature
