Main characteristics of heat resistant conveyor belt
The conveyor belt is mainly used for metallurgy, building materials, casting, coking, chemical industry, transport sinter, coke, cement, chemical fertilizer, and other high temperature solid material, with the heat resistance of the provisions. The heat resistance and service life of heat resistant conveyor belts mainly depend on the heat resistance of the coating and the core. General with good heat resistance rubber, such as: styrene butadiene rubber, butyl rubber, ethylene propylene rubber as main glue material, to heat, heat shrinkage of polyester cotton, polyester and nylon canvas belt core. Heat resistant conveyor belts are divided into four grades according to the test temperature. T1: the test temperature is not greater than 100, T2: the test temperature is not greater than 125, T3: the test temperature is not greater than 150, T4: the test temperature is not greater than 175. The strength and width of the heat resistant conveyor belts are the same as the ordinary conveyer belts. Tape marking example: 2001200 8+3 51000 T2 200m said the belt length EP, width 1200mm, with core EP canvas of a total of five layers, the strength of the specifications for 1000N/mm, the upper and lower cover of the 8mm and 3mm, the cover layer can be heat resistance is not greater than 125. The product implementation of the GB/T 20021 - 2005 "canvas heat transfer belt" national standards. In order to meet the higher temperature, some manufacturers also have developed a higher temperature capability level of heat resistant conveyor belt and the burning heat resistant conveyor belt, is generally in covering layer compound flame retardant insulation agent, anti erosion agent, conductive agent, in order to improve the adhesive tape high temperature anti erosion performance.
