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 100ºC, the max. short-time operating temperature is 150ºC,the symbol is T1.
Type II; it is able to resist the test temperature of no more than 125ºC, the max. short-time operating temperature is 170ºC,the symbol is T2.
Type III; it is able to resist the test temperature of no more than 150ºC, the max. short-time operating temperature is 200ºC,the symbol is T3.
Type IV; it is able to resist the test temperature of no more than 175ºC, the max. short-time operating temperature is 230ºC,the symbol is T4.
4,The Heat Resistance Conveyor Belt physical property of the cover rubber after heat test shall conform to the values specified in the table.
5,The heat resistance conveyor belt abrasive wear of the cover rubber
6,The heat resistance conveyor belt layer to layer adhesion strength
