Rubber products are widely used in mining, metallurgy, automobiles, all kinds of machinery, etc., resistant tubing has irreplaceable primary effect. Since the founding of the People's Republic of China, especially since the reform and opening up, China's high-pressure hose and belt industry has developed. Now, China's high pressure hose can not only meet the needs of the domestic market, but also gradually enter the world market.
1.
Production capacity ranks among the best in the world At present, there are nearly 1,000 high-pressure hose and belt factories in the country, more than 300 tape factories with a certain production scale, and more than 100 hose factories. High pressure hose, belt production capacity and output continue to increase, it is estimated that the primary high pressure hose, belt product production capacity ranked among the world's best, respectively, conveyor belt 150 million square meters, V-belt 700 million A meters, various hose 300 million standard meters. It can fully meet the needs of our national economy and has some exports.
2, high pressure hose, with raw materials abroad some domestic
The raw materials used in high pressure hose and belt products in industrial developed countries mainly include natural rubber, general synthetic rubber such as styrene butadiene rubber, special synthetic rubber such as neoprene rubber, thermoplastic elastomer, synthetic resin, NN canvas, EP canvas, polyester cord, various rubber auxilaries, etc. Some of these raw materials are still blank in China 10 years ago, and now there are all of them. Its variety and quality are basically in line with domestic demand, and some products such as NN canvas, EP canvas, polyester cord and rubber additives are still exported. Very few raw materials that are not available in
China are also readily available. Relatively rich raw material costs have laid the foundation for many exports of high pressure hose and belt products in China.
3, product structure with the world
Since the reform and opening up, the high-pressure hose and belt industry have vigorously adjusted the product structure and achieved remarkable results. The proportion of chemical fiber belt, steel wire belt, PVC belt, PVG belt exceeds 90%, and the proportion of traditional cotton canvas belt is less than 10%, which is suitable for industrial developed countries; The proportion of V-belt in the V-belt structure exceeds 50%, close to the world's advanced level; The proportion of chemical fiber coiled pipe, braided pipe, knitted pipe, wire braided pipe, coiled pipe and resin hose exceeds 60%, which is also close to the world advanced level. Because the product structure is in line with the world, it is conducive to the export of high-pressure hose and belt products in China.
4, the level of skills and equipment close to the world's advanced level
After the introduction and digestion and absorption of China's high pressure hose and skill equipment, its equipment production and the skill and equipment level of the primary company has been close to the world's advanced level, such as steel wire conveyor belt production line, coated V-belt production line, fiber coil hose production line, etc., its equipment performance and automatic control level are relatively high.
Domestic industry is rapidly developing, together with the study and reference to foreign advanced equipment is also essential, resistant tubing products can fully meet the current world mechanical engineering and other aspects of high pressure hose demand, cost-effective overthrow fantasy!
