According to Li Hong, Secretary-General of the China Rubber Association, the six topics to be developed are: high-strength straight-latitude high-strength fabric core conveyor belts, heat-resistant high-temperature conveyor belts, automotive elastic multi-ribbed belts, and multi-ribbed belts Research on the safety of polycyclic aromatic hydrocarbons in new high-strength skeleton materials and tape products, such as molding process, polyester tempered brown silk for transmission belts, etc.
The straight straight weft fabric core is the replacement product of the medium and high strength layered fabric core conveyor belt, and it is also a typical product with a few layers of the fabric core conveyor belt. At present, there is a big gap between domestic products and foreign advanced level, and the conveyor belt structure should be enlarged. , process and equipment independent innovation R & D efforts; With the development of metallurgy, building materials industry, the demand for heat-resistant high temperature conveyor belt is increasing, the performance requirements are also higher and higher, must further improve the existing heat and high temperature transport The heat-resisting and high-temperature resistant grades and the prolonged service life of the belts, especially the research of the tape structure, skeleton materials and rubber compounds; China has been able to produce a variety of automotive multi-wedge belts, but some high-end cars need to import multi-wedge belts. The elastic multi-ribbed belt is an urgently needed product for autos. Therefore, it is necessary to improve the rubber temperature performance, process and equipment, etc., so that it can meet the enterprise standards of the related automobile manufacturers; multi-wedge belt molding vulcanization molding process can save raw materials and reduce Wastewater and noise pollution should be further studied in the formulation of rubber compounds and tape structure in order to meet the needs of energy conservation, emission reduction and environmental protection; It was untwisted filament structure, since the less extensible and not loose, can effectively increase the belt life and energy saving, cutting-edge technology belt drive belongs to the skeleton, but the technical development difficult, and therefore should be practical advance.
In addition, due to the strict requirements on the content of polycyclic aromatic hydrocarbons (PAHs) in rubber products including adhesive tapes after the European REACH Regulations and relevant US regulations were promulgated, it is necessary to study the chemicals used in the tape industry in China so that the tape products meet the EU and the United States. The relevant new laws and regulations not only benefit the protection of the human body, the environment and ecology, but also facilitate the export of tape products.
The total consumption of raw rubber in the tape industry in China is already ranked first in the world. During the “Eleventh Five-Year Plan†period, Chinese tape products have greatly improved in terms of quantity, scale, and overall technology level, but they have not yet escaped extensive growth. The method still has a big gap compared with the international advanced level. To this end, the China Rubber Industry Association, in formulating the "Twelfth Five-Year Plan" for the tape industry, proposed to focus on six practical issues. This is the information that the reporter received at the 2010 International Forum on Hose Tape Information and Technology organized by the China Rubber Industry Association's Ribbon and Tube Branch on October 20.
