Introduction to the Development of Conveyor Belt

1. Product Introduction of Conveyor Belts. Conveyor belts are generally composed of three parts: skeleton material, covering layer and bonding layer material (the following covering layer and bonding layer are collectively referred to as "covering layer") and primer material. Among them: skeleton material is conveyor belt The key to bearing is the decisive factor of the conveyor belt's directivity, load capacity and extensibility; the cover layer material is the guarantee of the conveyor belt's normal operation, and it has the protection of the skeleton material, the transport material, the increase of the friction coefficient, the absorption of the material impact, the anti-wear, etc. Function, the characteristics of the conveyor belt such as high temperature resistance, wear resistance, anti-static, etc. all depend on the characteristics of the cover layer material; the role of the primer material is to make the framework material and the cover layer have good adhesion strength. According to the material of the cover layer, the conveyor belt can be generally divided into rubber conveyor belt and light conveyor belt. The former's cover layer mainly uses various types of modified natural or synthetic rubber, and the latter uses various types of polymer modified materials. Including modified PVC, PE, TPU, TPEE materials, etc.

Rubber conveyor belt is mainly used for the transportation of heavy materials in the heavy industry. Its main application areas include the traditional five major industries of steel, coal, cement, port and power, accounting for more than 90% of the downstream market of the conveyor belt. Light conveyor belts are mainly used in the light industry and agriculture to carry and transport products on automated production lines. In some industries such as food processing, textile printing and dyeing, etc., conveyor belts also participate in the processing process.

At present, the application of powered conveyor belt has penetrated into all walks of life of the national economy and is inseparable from the daily operation of the national economy.

Building material conveyor belt supplier believes that the downstream applications of rubber conveyor belts have not changed much in the past decades, and are still mainly based on traditional heavy industry and mining, and are oriented according to the special requirements of these industries High temperature resistance, flame retardant, high strength and other directions; and the downstream application areas of light conveyor belts are increasing, from the initial light industry electronic production line to textile printing and dyeing, stone wood processing, food processing, etc., in addition to traditional steel, Almost all fields other than the five major industries such as coal, power, cement, and ports are currently available. Its performance and application fields continue to develop with the development of polymer material modification technology. In the conveyor belt industry, lightweight conveyor belts represent the development direction of lightweight, safe, environmentally friendly and energy-saving conveyor belts.

2. Overview of the conveyor belt industry market Globally, with the economic development of the conveyor belt industry, its overall market size has maintained steady growth. At present, the global conveyor belt market scale is about 600-700 million square meters per year, and is mainly based on rubber conveyor belts, accounting for 85% -90% of the conveyor belt market usage, and light conveyor belts account for only 10% -15% .

3. 3. Global energy saving and environmental protection trends will increase the proportion of light conveyor belts in conveyor belts. Compared with traditional rubber conveyor belts, new material lightweight conveyor belts have many advantages: First, they are safer and more hygienic. Compared with traditional conveyor belts, TPU products and food-grade PVC conveyor belts are widely used in food processing, agricultural production and other industries because they meet the strict standards of EU and FDA, while TPEE and PE conveyor belts are non-toxic due to their surface materials. The requirements are used as the main belt in the tobacco industry; secondly, modification is relatively easy and can meet diverse performance requirements. In addition to the good characteristics of the cover material itself, through physical and chemical modification, the new material light conveyor belt products can be equipped with acid and alkali resistance, oil resistance and organic solvent characteristics, to meet the diversified use needs of downstream industries; again, in performance Under similar circumstances, the weight and thickness of the new material light conveyor belt is much smaller than that of the rubber conveyor belt, and the flexibility is better. The required wheel diameter of the equipment is also much smaller, so it is more energy-efficient. Therefore, from a global perspective, as the international development of new green and environmentally friendly materials and the increasing awareness of environmental protection and energy saving, the conveyor belt industry will develop in the direction of light and thin, energy saving, safety, and environmental protection in the future. The proportion in the belt industry is gradually increasing. In more and more fields, it gradually replaces ordinary rubber conveyor belts, and the market demand continues to expand.
