The use and characteristics of the oil belt
Oil Resistant Conveyor Belt there are many, so widely used, then you are also aware of his characteristics? Check it out together!
Uses: General Conveyor Belt on a variety of oils, organic solvent tolerance of the relatively poor. Transport of materials like oil, because oil on the rubber band with a decent swelling, erosion, making the surface of plastic volume increase, structural relaxation, physical and mechanical properties decreased, shortened product life. Oil Resistant Conveyor Belt from the cotton canvas, nylon canvas, polyester canvas, after rolling, forming, curing and other refining processes, with good oil resistance, suitable for conveying oily materials, and some may be oily, chemical solvents occasions Use.
Features: plastic cover used good oil resistance of nitrile rubber, reinforced materials can be selected according to the different needs of different materials.
Plastic cover with high acrylonitrile content of nitrile rubber as the main material, the use of canvas, nylon canvas or polyester canvas is a strong layer. Transmission oil for various work materials or exposure to the oil environment. Have low specific volume change, strength to maintain a high, the use of a wide range of advantages.

The distinction between the types of conveyor belt and Recognition
The distinction between the types of conveyor belt and Recognition
Called the transport conveyor belt, conveyor belt for carrying and transportation of materials play the role of the rubber and fiber, metal composite products, plastics and fabrics or composite products. Belt conveyor in the agricultural, industrial and mining enterprises and transportation in a variety of widely used to transport solid bulk and powder-like material or into items, conveyor belts can be continuous, high efficiency, large angle transport, conveyor belt safe operation, conveyor belt is easy to use, easy maintenance, low shipping costs, and shorten the transport distance, reducing construction costs, save manpower and resources
Many types of conveyor belt, in accordance with the use classification are: general purpose conveyor belts, flame-retardant anti-static conveyor belt, Rubber Conveyor Belt, heat-resistant conveyor belt, heat resistant conveyor belt, acid and alkali conveyor belt, oil resistant conveyor belt, cold resistant conveyor belt and so on.
Classified according to structural materials are: ordinary cotton canvas belt, nylon conveyor belt, polyester belt, steel cord conveyor belt, PVC solid woven conveyor belt, PVG solid woven conveyor belt, steel cable conveyor belt and so on.
Structure by product category are: layered belt, the whole conveyor belt, steel cord conveyor belt, steel cable conveyor belt, pipe conveyor, pattern conveyor belt, sidewall conveyor belt, conveyor belt, etc. by layer.
For convenience, we generally use a unified representation to represent a variety of conveyor belt, various types of conveyor belt that way
1, hierarchical representation of belt used (the standard representation of different, specific requirements, please refer to the standard GB7984): to NN200 1000 × 6 (6 +3) as an example, NN200 that is nylon 200, 1000 – The width of said tape, 6 -, said nylon layers, (6 +3) – that cover the upper and lower rubber conveyor belt were 6 mm and 3 mm thick.
2, said steel cord conveyor belt used Method: ST1000 H 1000? 4.0-6.0-6.0 example: ST1000-that is the strength specifications for 1000N/mm H-that is the level of performance rubber cover 1000 – that the products Width, unit mm? 4.0-that is the wire diameter, unit mm 6.0-6.0-that is the thickness of the upper and lower plastic cover, unit mm
3, the whole conveyor belt of the representation of the general coal with PVC and PVG conveyor belt with the whole strength flame retardant grade and width of the belt, said. Intensity level usually divided into: 4, 5, 6, 7, 8, 9, 10, 11, and up to 16 bands corresponding to the intensity: 680S, 800S, 1000S, 1250S, 1400S, 1600S, 1800S, 2000S, 2240S, 2500s, 2800S, 3100S and 3400S. Conveyor widths are: 500mm, 650mm, 800mm, 1000mm, 1200mm, 1400mm, 1600mm, 1800mm and so on.
China requires all coal mine conveyor belt used in our products must meet the relevant standards for the flame-retardant anti-static belt. Coal companies are now commonly used in conveyor belt: PVC flame retardant solid anti-static conveyor belt, PVG solid woven conveyor belt fire-retardant anti-static, flame-retardant anti-static steel cord conveyor belt. The main provisions of flame-retardant anti-static belt safety performance of the product: 1, alcohol burner combustion; 2, surface resistance; 3, roller friction; 4, analog gateway propane combustion. The test project to characterize the safety of products.
