Mining ST2000 steel wire rope core rubber conveyor belt

The steel rope core conveyor belt is made of rubber covered with steel rope core liner as the traction and carrying component of the belt conveyor
Characteristics of steel cord conveyor belt: high tensile strength, good impact resistance, long service life, small service elongation, good grooving performance, good bending resistance and flexibility, suitable for long-distance, long haul and high-speed conveying of materials
The product is composed of core glue, steel wire rope, covering layer and edge glue
It is widely used to transport materials in coal, mining, port, metallurgy, electric power, chemical industry and other fields
Chinese Name: steel wire rope core conveyor belt can be divided into ordinary type and flame retardant type   In: coal, mine and port standards   Standard: common type shall comply with gb/t9770-2001
Type: it can be divided into: common type, flame retardant type, heat resistant type, wear resistant type, cold resistant type, acid and alkali resistant type, oil resistant type, etc
according to the covering rubber properties
Technical standards: gb/t9770-2001 for ordinary type, g2539-93 for cold resistant type, g2539-93 for ozone resistant type, hg/t3646-1999 for acid and alkali resistant type, hg/t3646-1999 for heat resistant type, and mt668-1997 for flame retardant type
Joint introduction 1
Joint methods conveyor belt joint methods include: mechanical joint, cold bonding joint, hot vulcanization joint and other common methods
Mechanical joint generally refers to the use of belt buckle joint, which is convenient, fast and economical, but the joint is inefficient and easy to be damaged, which has a certain impact on the service life of conveyor belt products
In PVC and PVG whole core flame retardant and antistatic conveyor belt joints, this joint method is generally used for products below grade 8 belt
Cold bonded joints, i
e
joints with cold bonded adhesives
This joint method is more efficient and economical than mechanical joint
It should have a better joint effect
However, in practice, it is not very stable because the process conditions are difficult to master and the quality of adhesive has a great impact on the joint
The practice has proved that the hot vulcanization joint is the most ideal joint method, which can ensure high joint efficiency, and is also very stable
The service life of the joint is also very long and easy to master
However, there are some disadvantages, such as troublesome process, high cost, long joint operation time and so on
2
The joints of the layered conveyor belt can adopt mechanical joints, cold bonding joints, hot vulcanization joints and other joint methods as required
Generally, cold bonded joints and hot vulcanized joints adopt stepped structure joints
3
The joints of PVC and PVG whole core flame retardant conveyor belts are not easy because of the special structure of the whole core belt, so most of them adopt the mechanical joint method, that is, the belt buckle joint
However, for belts above grade 8, in order to ensure the joint effect, the method of hot vulcanization joint is generally adopted
The structure of joints is finger joint
The heat vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is relatively complex, and the requirements for equipment are also relatively high
4
Joint of steel wire rope core conveyor belt the joint of steel wire rope core conveyor belt is the most complex of all conveyor belt joint technologies, not only the process is more complex, but also the designed joint size parameters are the most
Different grade products have different joint structures
