     Conveyor belt at the strength of joints than normal with lower body strength. Generally connected by mechanical means, the joint strength can only be achieved with 40-50% body strength, relatively good quality, conveyor belt manufacturer cold-glue method, the joint strength can reach 60-70%, while the hot glue joint strength can reach 80-90% ( joint approach is correct, no quality defects). As the strength of joints is relatively low, if the bonding Polyester Conveyor Belt method is not correct, the joint strength will be even lower, such as surgery, injured, under a layer of cloth when polishing, grinding over-lap length is not enough, the number of steps is not enough glue joints The poor performance of rubber, or has expired since the sulfur, over-polished steel wire rope, wire rope rusty and so on, the strength of joints will be greatly reduced, in use, prone to the phenomenon of broken joints.
In addition, the conveyor belt if you do not use sealing glue, or glue joints in the wrong direction, the joints prone to cracking (surface plastic parts).

Abstract The fixed conveyor belt of cold seamless multi-layer, according to the use of rubber conveyor belt conveyor belt of the intensity of choice to seamlessly connect the length of the cold, as well as the determination of the direction of overlap.
Key words multi-layer rubber conveyor belt cold seamless connection

 1, the status of foreign fire-retardant conveyor belt conveyor belt

Underground coal mine conveyor belt is the main tool, due to the traditional rubber conveyor belt was flammable and could not meet the requirements of underground fire-retardant, therefore, the Department of States to prohibit the use of downhole. Flame-retardant flame-retardant and antistatic conveyor belt easy to do, and because with a waterproof, moisture-proof, tear-resistant, light weight, energy consumption, etc., and therefore countries in the world widely coal mine applications. At present, some of the world industrially developed countries in coal mine conveyor belt used in 4000N/mm almost all of the following PVC, PVG flame-retardant conveyor belt, thus the use of particularly large, accounting for almost one-third of the world’s belt use 1. Among them, British and German production technology and product quality, representing the world’s advanced level. Some industrial developed countries can produce a strength grade of more than 4000N/mm, width more than 3500mm of the flame-retardant conveyor belt, the useful life of more than 10 years, can completely replace the steel cord conveyor belt, and because of price, consumption, tear-resistant, roadway space occupied by both, and therefore, than the steel cord conveyor belt more competitive. conveyor belt manufacturer

2, the status quo of China’s flame-retardant conveyor beltPolyester Conveyor Belt

China is a coal-producing country, accounting for underground conveyor belt with the world. Because China’s coal mine transport conditions are generally poor, the safety belt is particularly important. China from the last century began 80 years to develop and promote the use of flame-retardant conveyor belt, for which the state has issued a MT147.87, MT147-92, MT147-95, MT914-2002 and other industry standards, and implementation of flame-retardant conveyor belt 3 card check certification, safety signs Zhunyong Zheng and production license) management, so that our fire-retardant conveyor belt production, use, management gradually standardized and scientific, and effectively ensure the use of coal mine conveyor belt安全. Through 20 years of development, China has become the world’s PVC, PVG conveyor belt flame-retardant fabric production capacity of the entire core of the country’s largest production capacity of up to 80 million square meters. Since the flame-retardant conveyor belt of States for implementation of “three card” management, the nation’s coal mine not a single case of fire caused due to conveyor belt accident.

3, flame-retardant conveyor belt of China’s gap with foreign countries

① the lack of core technology and independent innovation capacity is weak. China’s PVC, PVG entire core fire-retardant fabric manufacturers of conveyor belt are mostly small and medium enterprises, in addition to foreign investment and joint venture enterprises, only a few large enterprises have the national or provincial tape technology center, a dedicated R & D team, the more perfect the The experimental equipment and testing instruments, have a certain ability to innovate. The foreign production PVC, PVG flame-retardant conveyor belt of world-renowned manufacturers, mostly large enterprises, with strong core technology and independent innovation capability, in the manufacture of products, but also the creation of products, manufacturing products of domestic and not the vast majority of enterprises are not allowed to create products.

② process equipment and production technology level is not high, the lower end products. Domestic enterprises, the production of PVC flame-retardant conveyor belt technology has been relatively mature, but the PVG flame-retardant conveyor belt technical level of production is still relatively low. The first is relatively backward and complex production processes, energy consumption, low production efficiency, and because with a body after a serious decline in intensity after the second plastics. The most advanced production technology is used extruder veneer molding process, eliminating the traditional production process of rubber mixing, molding, curing and other flat-panel technology, achieved with a core leaching from the paste, plastic, covering glue together , curing the continuous production, the production efficiency greatly improved. At present, China’s production of the highest strength grade PVC, PVG flame-retardant conveyor belt of 2500N/mm, maximum width of 2000mm, while the intensity of foreign produce 4000N/mm, width more than 3500mm the entire core flame-retardant fabric belt.

③ carrying capacity is poor, and short service life. China’s PVC, PVG flame-retardant conveyor belt carrying capacity and service life of most less developed countries, to use the largest 1000S flame-retardant conveyor belt, for example, domestic life of tape is generally not more than 2 years, the cumulative amount of not more than 200 coal million tons, while the useful life of similar products abroad, more than four years, the cumulative amount of more than 6 million tons coal. Steel Cord Conveyor Belt

4, the development trend of China’s flame-retardant conveyor belt

① large size, high strength, light weight and longevity of. With the development of the coal industry, a large number of 5 million tons or even more than 10 million tons of large-scale mines coming on stream, large size, high-intensity growing demand for flame-retardant conveyor belt, extra large mines require the use of even more than the width of more than 1600mm 3000mm, even stronger than the 2500N/mm even reached 4000N/mm flame-retardant conveyor belt, this conveyor belt carrying a large amount of long distance transport, therefore, require high strength, long service life, must be vulcanized joints; also asked with a thin body , light weight, in order to facilitate investment and savings in energy consumption, a new type of skeleton material must be used in order to meet the requirements.

② materials, new technology, production and continuous. Flame-retardant conveyor belt as a whole depends largely on the strength of the material with a core, at present, the domestic as a whole with a core of the latitude and longitude are based on polyester / cotton or nylon / cotton yarn, they have with body thickness, weight, large, low intensity. The general use of foreign as polyester or aramid warp, weft of polyamide and cotton yarn, which with core thin, light weight, high strength. With the high-performance, thin, lightweight development trend of the overall intensity of more than 3000N/mm with aramid core priority should be given to make the warp, it will give the body with thin, light weight, in order to facilitate dipping and plastics , so that substantial increase in the strength of conveyor belt, longer life.

③ species diversity, use of broad-based. The current domestic PVC, PVG conveyor belt flame-retardant used primarily in the coal mine. In fact, in addition to other high-temperature materials, it can be adapted to any place under the material handling. Abroad, not only coal mine use flame-retardant conveyor belt, as well as coal mine on the ground to use general-purpose flame-retardant conveyor belt and the non-coal industry, general-purpose use of conveyor belt, only coal mine with the flame-retardant flame-retardant conveyor belt of the more stringent performance requirements only. Pipe Conveyor Belt

④ energy saving, safety and environmental protection. Energy-saving, safety and environmental protection is the development of the industry trend of conveyor belt, PVC, PVG flame-retardant conveyor belt itself is a energy-saving, safe and environmentally friendly products. High strength flame-retardant conveyor belt long life, rechargeable hair to play a resource efficiency, with a decent fire-retardant thermoplastic conveyor belt production process simple and low energy consumption, high efficiency, and the plastic material can be reused, are in accordance with circular economy energy-saving, safe and environmentally friendly products. Low toxicity, low smoke flame-retardant conveyor belt is more secure and environmentally friendly products.

⑤Rubber Conveyor Belt talent, technology, market and efficiency to a small number of enterprises are concentrated. China’s current PVC, PVG conveyor belt manufacturers of flame-retardant up to more than 80, mostly small businesses, large and medium sized enterprises have more than a dozen tape, while the production of similar products abroad, a total of only a dozen or so companies, mostly large-scale enterprises and world-renowned brands. In recent years, the domestic market and the effectiveness of flame-retardant conveyor belt is gradually to foreign-funded enterprises and medium-sized enterprises are concentrated. With the entry of foreign-funded enterprises and domestic tape industry, the quality of credit to carry out the activities and the implementation of brand strategy, and effectiveness of such a market to a small number of strong corporate focus is increasingly evident, while in human resources, capital, technology, etc. are gradually transferred to a small number of strong corporate .
