6mm-30mm Heat-resistant conveyor belt ST1600 Special Conveyor Belts
1. Product features
The heat-resistant conveyor belt is made of multi-layer rubber
cotton canvas (polyester cotton cloth) covered with
high-temperature or heat-resistant rubber and bonded together by
high-temperature vulcanization. It is suitable for conveying hot
coke, cement, molten slag and hot castings below 240℃. . 1. The
specifications are the same as ordinary conveyor belts. 2. The
product implements HG2297-92 and GB/T20021-2005 standards. 3.
Heat-resistant conveyor belts can be divided into five types: Type
Ⅰ: can withstand test temperature not greater than 100℃, maximum
short-time operating temperature is 150℃, code T1. Type Ⅱ: It can
withstand the test temperature of not more than 125℃, the highest
short-time operating temperature is 170℃, and the code is T2. Type
Ⅲ: can withstand test temperature not greater than 150℃, maximum
short-time operating temperature is 200℃, code T3. Type IV: can
withstand test temperature not greater than 175℃, maximum
short-time operating temperature is 400℃, code T4. V type: can
withstand test temperature not more than 240℃, maximum short-time
operating temperature is 600℃, code T5.
2. Formula design
1) National standard for each product: heat-resistant conveyor belt
implements HG 2297-92 standard
2) Performance requirements: (1) It can be used for a long time
under the condition of 150℃, and can be used for a short time under
the condition of higher than 150℃. (2) Not only must it have good
wear resistance at room temperature, but also require no
deterioration under high temperature conditions. (3) There must be
a certain degree of self-adhesiveness and mutual adhesion with the
cushioning rubber before vulcanization, and higher adhesive
strength after vulcanization. (4) The hardness and tensile
properties meet the requirements.
