Detailed Description

1、Heat Resistant Conveyor Belt Feature: 　　The heat resistance conveyor belt is made of the multilayer rubber cotton canvas ‘polyester cotton’ covered with the high temperature or heat resistant rubbers, which are bonded through high temperature vulcanization, it is applicable to conveying of the coke, cement, clinker and hot casting etc. 　　 1、The heat resistance conveyor belt’s specification shall be identical with that of the conventional conveyor belt. 　　 2、The heat resistance conveyor belt shall be in accordance with HG2297-92. 　　 3、The heat resistant conveyor belt contains three types. 　　　Type I; it is able to resist the test temperature of no more than 100℃, the max. short-time operating temperature is 150℃，the symbol is T1. Type II; it is able to resist the test temperature of no more than 125℃, the max. short-time operating temperature is 170℃，the symbol is T2. Type III; it is able to resist the test temperature of no more than 150℃, the max. short-time operating temperature is 200℃，the symbol is T3. Type IV; it is able to resist the test temperature of no more than 175℃, the max. short-time operating temperature is 230℃，the symbol is T4. 2、The heat resistance conveyor belt physical property of the cover rubber after heat test shall conform to the values specified in the table. Item type type I type II type III variable range Hardness Difference before and after ageing (IRHD) ±20 Max. Value after ageing (IRHD) 85 Tensile strength variable rate in performance ≤ 25 30 40 Min. value after ageing Mpa 12 10 5 Rate of elongation at break variable rate in performance% ≤ 50 55 Min. value after ageing 200 180 3、The heat resistance conveyor belt abrasive wear of the cover rubber Type Item level Abrasive wear type I type II type III First quality 0.8 1.0 1.0 accepts 1.0 1.2 1.2 4、The heat resistance conveyor belt layer to layer adhesion strength Item interlayer of cloth cover layer and cloth interlayer Thickness of the cover layer≤1.5mm Thickness of the cover layer＞1.5mm The average value of the longitudinal specimen shall be no less than 3.0 2.2 2.6 The peak value of the longitudinal specimen 2.0 1.6 2.0
