The adhesive skills of nylon conveyor belt
2024-05-18 16:08 Last year in February, our company shipped a 330-meter nylon conveyor with a bandwidth of 1200mm to a coal mine in North Africa for the transmission and transportation of mining materials.
Nylon conveyor belt, the middle canvas is nylon canvas.
Nylon (NN) conveyor belt has the characteristics of thin belt body, high strength, impact resistance, good groove formation, strong inter-layer adhesion, excellent flexibility and long service life.
It is suitable for medium and long distances and high load capacity. , transporting materials under high-speed conditions, widely used in mining, coal fields, chemical industry, metallurgy, construction, ports and other departments.
Nylon conveyor belt are extensively used in mining, coal fields, metallurgy, construction, ports and other departments. Nylon conveyor belt is suitable for conveying the non corrosive and non sharp lumpy, granular and powdery materials at room temperatures. Such as coal, coke, sand and gravel, cement and other bulk materials or finished objects. Transporting the accumulation density of various bulk, granular, powdery materials of 6.5~2.5t/m3.
Selecting and sizing of adhesives. Adhesives are generally in barrels and should be in the form of a paste after being mixed with the curing agent. The adhesive used to bond conveyor belt joints should be thinner. The relationship diagram between adhesive layer thickness and shear strength. Due to the thin glue layer is not prone to generate flow and creep, the probability of bubbles and defects is smaller and the internal stress on the interface will be smaller too. Hence, it is beneficial to improve the bonding force of the interface. However when the glue layer is too thin, it is easy to form a lack of adhesive and the coating is discontinuous which can also reduce the strength of the bonding strength.
Thereby, when applying the adhesive the thickness of the coating should be guaranteed there is no shortage of glue. The determination of the bonding timing and when two parts of the interface are overlapped will directly affect the bonding effect. Compared with its transportation method, using the nylon conveyor belts as the transportation carriers has the advantages of safe operation, shorten the transportation distance and other advantages. Nylon conveyor belt has become the substitute for road, rail way in a certain range.
This kind of conveyor belt suits for transporting non special corrosiveness at room temperature block, granular and powdery in a general condition. In the transportation and the storage of the conveyor belt should be kept clean and be avoid to get sunlight directly or rain and snow, prevent contact with acids, alkalis, oil, organic solvents and other substance. And keep it one meter away from the heating devices. When storage the ware house temperature should be keep between-18°C and 40°C, the relative humidity should be maintained between 50-80%.
During storage, products should be placed in a roll, should not be folded, they should be turned once a quarter during the placement period. Different types, specifications and layers of conveyor belt should not be joint together. The best joint method of its is applying the glue joint method. The type, structure, specification, the number of layers of conveyor belt should be selected reasonably accorded to the using condition. The operation speed of conveyor belt usually lower than 2,5/m, large block, abrasiveness of materials and use of the fixed type of unloading device should be adopted speed as slow as possible.
