Development status of polyester (EP)conveyor belt

The high-strength polyester fabric (EP) conveyor belt is a new type of conveyor belt composed of polyester cloth as a stretch material and polyvinyl chloride plastic as a cover rubber. It has higher strength and more than ordinary conveyor belts. Good performance. As one of the main components of the belt conveyor, the high-strength EP conveyor belt not only has the general function of ordinary conveyor belts, but also can be used in coal, mining, metallurgy, chemical industry, ceramics, cement, construction, transportation and other departments, becoming a large-scale continuous An important tool for transporting materials including lumps, granules, pastes or finished products. Can withstand higher load capacity and impact than ordinary conveyor belt, long service life, can work in harsh environments.

In our country, through the unremitting efforts of several generations of scientific and technological personnel, the production technology of conveyor belt has made great progress. Take the stretched material of the skeleton layer as an example. From the 1950s and 1960s using cotton fabric, to the early 1960s using vinylon, cotton vinylon or cotton wool interwoven fabric, to the early 1970s using cotton fabric and wire rope, to the 80s using polyester fabric(EP) In the 1980s, tensile materials continued to develop toward high strength.

From the perspective of the polymer materials used, a series of rubbers with unique properties such as butyl rubber, nitrile rubber, and butyl rubber have been introduced from natural rubber used in ordinary conveyor belts to have characteristics such as acid and alkali resistance, oil resistance, and cold resistance. In a special conveyor belt. In addition to neoprene rubber, flame-retardant conveyor belts have also introduced polyvinyl chloride plastics or rubber plastics, etc.

The variety and quality of polymers are sustainable. In the 1990s, with the advent of continuous fluidized production lines such as large frame flat vulcanizers and drum vulcanizers, conveyor belts with large widths and large spans also appeared. Due to the limitations of production equipment and process technology, most of the conveyor belts sold on the market so far are still old faces, with few highlights of high hardness and high performance, traditional conveyor belts have poor adaptability and short service life. These problems are particularly prominent in industries with strict transportation requirements, such as mining and ceramics. The high-strength, high-performance conveyor belt was born to meet the needs of science, technology and market.

SUNGDA has adopted a series of unique and effective technical measures in the combination of fabric and polyvinyl chloride in the mixing process and the molding and plasticizing of the entire conveyor belt, transplanting its own research results and the successful experience of others into new products. Practice has proved that the use performance and service life of the high-strength polyester fabric (EP) conveyor belt have received good results, and its market application prospect is very broad.
