Rubber belt selection to pay attention to what
Rubber conveyor belt: the shape and structure of the transportation mode of different types, such as flat, groove, angle, bending and turning conveyor, box, tubular, closed transmission, and the lifting conveyor, these different transportation mode depends on the conveyor belt conveying capacity, and will be affected by the terrain and environmental protection conditions, is determined with heavy-duty rubber tensile material, structure, safety coefficient, with the premise of the length of the belt;
Conveyor belt core material and structure choice: performance and great relationship with core material, structure and layers of conveyor belt, cotton canvas belt multilayer multiple layers, not low strength, fatigue resistance, easy to mildew corrosion, high weight, high energy consumption, high strength nylon belt, elastic, light weight, resistance shock resistance and good bending performance, the channel performance, the performance is better than that of water proofing, cotton canvas for ordinary frame transmission belt, its disadvantage is the elongation, when the tensioning stroke can be set longer may be the preferred choice of nylon rubber belt, polyester belt core strength and cotton fiber, has the advantages of nylon all the tape, the elastic modulus ratio of Nylon high, small elongation, good dimensional stability, is an ideal transport belt commonly used in industry, and the steel wire rope core conveyer belt with high strength, into a good groove, stretch The utility model has the advantages of small length, short tensioning schedule, and is especially suitable for conveying requirements of large volume, high speed and long distance;
Cover layer selection: covering layer selection includes coverage material, surface morphology and thickness, the main component is covering all kinds of rubber and plastic, in most climate circumstances, the rubber band will work at the angle of not more than flat conditions, and flame retardant conveyor angle belt normal operation is below one hundred and twenty degrees, although the main skeleton material as resilient rubber, but has good flame retardancy, discharging and cleaning, and because there is much difference on the performance of various kinds of rubber, such as natural rubber and styrene butadiene rubber with absorption and good abrasion resistance, EPDM rubber special heat-resistant, thiakol rubber oil resistance well, propylene butyl rubber is heat and oxidation resistant chemical action, so choose what type of cover material models, must be based on the species, commonly used materials operating conditions and working environment to fully Integrated consideration;
Additional cover thickness is also beneficial to improve the performance of rubber belt impact resistance and abrasion resistance, especially the cotton canvas belt core is synthetic fiber fabric core replaced with core performance has been greatly improved, and the thickness is relatively thinner, in order to make the whole performance of the overall improvement, there are necessary to improve the thickness of covering layer, in order to give full play to its advantages, improve the service life of the conveyor belt, but under the cover layer is too thick will make the heavy heat resistant conveyor belt running resistance becomes large, this need to pay attention to; running resistance of heat resistant conveyor belt becomes large, the need to pay attention to;
Additional technical knowledge in general design of tape thickness of coating layer is mainly rely on external factors according to the material of ring belt caused by the wear rate, different time by the material conditions, rubber transmission belt heat resistance and impact resistance of the coating and the belt conveyor running cycle determine when working, so the rubber conveyor belt manufacturer recommended customers in the selection of the belt as long as several points to ensure standard line rate, so the transportation equipment can be put in operation very satisfactory effect.
