China's tape industry has the largest consumption of raw rubber in the world. During the “Eleventh Five-Year Plan” period, China's tape products have greatly improved in terms of quantity, scale and overall technical level, but still have not shaken off the extensive growth. In the way, there is still a big gap compared with the international advanced level. To this end, the China Rubber Industry Association proposed to focus on six practical topics when formulating the “Twelfth Five-Year Plan” for the tape industry. This is the information obtained by the reporter on the 20th International Forum on Rubber Tape Information and Technology held by the China Rubber Industry Association Pipeline Branch on October 20.
Li Hong, secretary-general of the China Rubber Association with the branch, introduced six topics: diameter straight weft high-strength fabric core conveyor belt, heat-resistant high-temperature conveyor belt, automotive elastic V-ribbed belt, multi-ribbed belt molding vulcanization Research on the safety of polycyclic aromatic hydrocarbons in new high-strength framework materials and tape products for molding process, polyester tempered brown silk for transmission belts.
The straight through weft fabric core is a replacement product of the medium and high strength layered fabric core conveyor belt, and is also a typical product of the fabric core conveyor belt with less stratification. At present, the domestic products are far different from the foreign advanced level, and the conveyor belt structure should be increased. Independent innovation and research and development of technology and equipment; With the development of metallurgy and building materials industry, the demand for heat-resistant and high-temperature conveyor belts is increasing, and the performance requirements are getting higher and higher. It is necessary to further improve the existing heat-resistant and high-temperature-resistant conveyor. With heat resistance and high temperature resistance and long service life, special attention should be paid to the study of tape structure, skeleton materials and rubber materials; China has been able to produce all kinds of V-ribbed belts for automobiles, but some high-end cars have to be imported with multi-ribbed belts. The elastic V-ribbed belt is an urgently needed variety of automobile accessories. Therefore, it is necessary to improve the temperature performance, process and equipment of the rubber compound to meet the enterprise standard of the relevant automobile manufacturer; the multi-ribbed belt molding vulcanization molding process can save raw materials and reduce Waste water and noise pollution, further research on rubber compounding and tape structure should be carried out to cope with energy saving, emission reduction and environmental protection work; polyester
In addition, due to the strict requirements of the REACH regulations and the relevant US regulations, the content of polycyclic aromatic hydrocarbons in rubber products including tapes is required. Therefore, it is necessary to conduct research on the chemicals used in the tape industry in China, so that the tape products conform to the EU and the United States. The relevant new regulations, which not only benefit the human body, the environment and ecological protection, but also facilitate the export of tape products.
