1. Internal glue: polyurethane and butyl rubber are the main raw materials, and special reinforcing agent is added. The finished product is yellow and transparent. It has the characteristics of high wear resistance, high toughness and high pressure resistance. The wear resistance index is 2-3 times that of common sand-blasting rubber pipe. It enjoys the reputation of “wear-resistant king” in the same industry. Reinforcement layer: Sandblasting rubber pipe with sandwich cloth adopts high quality rubbing rubber cloth as reinforcement layer, which has good flexibility and strong pressure bearing capacity. 2. Acid and alkali (dilute) hose: used to attract dilute acid and alkali solution (except nitric acid) with concentration below 10% at room temperature 3. Water absorbing hose: 1. Composition: acid and alkali hose consists of inner rubber layer, fabric layer, spiral metal wire, medium rubber layer and outer rubber layer. 2. Performance and use: for agricultural irrigation, industrial and mining, civil engineering, and water conservancy projects to drain and absorb ambient temperature water 4. Oil transmission hose: composition: oil absorption hose is composed of inner rubber layer, fabric layer, spiral metal wire, middle rubber layer, outer rubber layer, can also use external armour structure. Performance and Application: It can be used for pumping gasoline, kerosene, diesel oil, lubricating oil and other mineral oils at room temperature. 5. The working pressure is 0.5-1.2 MPa 6. Usage: suction and drainage of oil, sediment, ash, etc., and gas drainage by dung suction tube of environmental sanitation tube.
