Product classification:
According to whether there is edge glue: wrapping belt and trimming belt.
According to the framework material: nylon (NN) canvas core conveyor belt (nylon belt, NN belt for short);
Polyester (EP) canvas core conveyor belt (referred to as polyester belt, EP belt).
Purpose:
It is widely used in coal, mining, port, metallurgy, electric power, chemical industry, casting, building materials, cement and other industries and places that need high-speed and fast transportation of materials, and it is used to transport non corrosive block, granular, powder materials, bulk materials or finished articles.
Structure:
The common fabric core conveyor belt is made of multi-layer impregnated nylon (NN) canvas and polyester (EP) canvas as the skeleton material, covered with covering rubber with different properties, and manufactured through calendering, molding, vulcanization and other processes.
Features:
Nylon (NN) canvas core conveyor belt has the advantages of light belt body, good elasticity, high strength, impact resistance and grooving. It is suitable for conveying materials in medium and long distance, large volume and high speed.
Polyester (EP) canvas core conveyor belt has the advantages of high initial modulus, good thermal stability of belt body size, high strength, small elongation and impact resistance. It is suitable for conveying materials in medium and long distance, large volume and high speed.
