国内外胶管发展动态

Development Trend of Rubber Hose

工业发达国家胶管以编缠结构为主，树脂软管的产量占胶管的５０％以上，复合结构胶管正在开发；胶管生产主要采用抽真空冷喂料挤出机和剪切机头挤出机，复合挤出工艺正在逐步推广使用。我国４０％的胶管为编缠结构，树脂软管的产量占胶管的１０％，产品结构的调整是当前的首要任务；大量从美国、德国、意大利和日本等引进生产线，工艺装备水平有较大提高；存在着新产品开发力度不够、整体工艺装备水平低和受外系统冲击严重等问题。

In the developed countries,the most rubber hoses are produced with the woven or wound carcasses,the resin tube accounts for over 50% of the total rubber hose output;the coldfeed vacuum extruder and the shear head extruder are widely used in the rubber hose production,and the co-extrusion technology is introduced progressively. In China, 40% of the rubber hoses are produced with the woven or wound carcasses, the resin tube accounts for 10% of the total rubber hose output;a lot of production lines imported from USA,Germany,ltaly and Japan have made the technology and equipment of rubber hose industry in China improve significantly.
