Compared with foreign countries the lack of fire-retardant conveyor belt

One, carrying capacity is poor, life is short. Of PVC, PVG flame retardant conveyor belt carrying capacity and life of most less developed countries to use the largest 1000S retardant Elevator conveyor, for example, the domestic life of the tape is generally not more than two years, the amount does not exceed the cumulative coal

More than 200 million tons, while the useful life of similar products abroad more than 4 years, the cumulative amount of more than 6 million tons coal.

Second, the lack of core technology, independent innovation ability is poor. Our PVC, PVG whole flame retardant fabric vertical conveyor manufacturers, mostly small and medium enterprises, and foreign produce PVC, PVG flame retardant conveyor belt manufacturers and more for the world famous enterprises, with strong core technology and independent

Innovation in the manufacture of the product while creating products, while most domestic companies manufacture products not only to create products.

Third, the process equipment and production technology level is not high, the lower grade of products. Domestic enterprises, flame-retardant PVC conveyor belt production technology is more mature, but PVG retardant conveyor belt production technology level is still low. The first is relatively backward and complex production processes, energy consumption,

Low productivity, and because the band body through the second plasticizing strength severely decreased. The most advanced production technology is the use of an extruder veneer molding process, eliminating the traditional production process of mixing, shaping, vulcanizing and other processes to achieve with a core leaching paste, plastic, covered

Cover stickers, vulcanized continuous production, the production efficiency greatly improved. At present, China's production of the highest strength grade PVC, PVG flame retardant conveyor is 2500N/mm, a maximum width of 2000mm, while foreign produce strength 4000N/mm, of a width exceeding 3500mm

Whole flame retardant fabric conveyor belt.
