Mine flame-retardant steel cord conveyor belt is used as the backbone of a high rope strength conveyor belt. It has a high tensile strength, elongation is small, tensioning short trip into the groove and dynamic performance and good features, mainly used in coal mine roadway main long-distance, high-load, high-speed conveyor.
Mine flame-retardant steel cord conveyor belt is a complex production process, high-tech products. The product is galvanized steel wire rope for the longitudinal reinforcing material. According to user requirements, some products added to the strip as transverse reinforced tear layer, the layer structure is the horizontal rope (wire rope or synthetic), or the use of hanging plastic mesh (steel wire cloth or fiber mesh ).
Since coal flame retardant steel cord conveyor belt complex structure determines the complexity of the process and recipe particularity. This is the coal flame retardant steel cord conveyor belt developed key technical issues, production technology, formulation and curing parameters are described. A reinforcing material (vertical rope) choice
Skeleton material is based on the strength of steel cord conveyor belt specifications use different diameters, different structures rope. Currently, steel cord conveyor belt rope with copper, zinc two kinds, because copper wire is easy to rust, so that shorten the life of steel cord conveyor belt. Therefore, the choice of galvanized steel wire rope for reinforcing materials. The structure with the rope belt as standard with 6 × 7 IWS, 6 × 19 IWS, 6 × 19W IWS3 kind.
The same diameter, different structures, its strength, flexibility and adhesive properties of the rubber are different. To this end, according to the steel cord conveyor belt and the use of performance standards to determine steel cord conveyor belt steel cord conveyor belt specifications for ST630-ST1000, wire rope structure used 6 × 7 IWS; steel cord conveyor belt specifications for the ST1250-ST2800, wire rope structure optional 6 × 19 IWS, steel cord conveyor belt specifications for ST3150-ST5400, wire rope structure used 6 × 19W IWS.
