Description

 1.application:

   used for for line delivery pumps, shotcrete machinery , boom pump trucks, distributors, CSG.
2. product structure: inner layer rubber, enhancement layer, outside layer rubber

(1) inner layer rubber:

       polyurethane and butyl rubber are the mainly material, and put in special reinforced material to make mixed rubber .Its colour is black and transparent. With high wear resistance, high toughness, high pressure, smooth, and so on.The friction resistance of concrete wipe, tube has the pressure transmission medium, wire protection from erosion effect.
Referring to the technical parameters of aircraft tire rubber, the inner rubber adopts high quality natural rubber, new accelerator, green environmental protection antioxidant and other raw materials. The wear coefficient is increased from 0.111 cm to 0.069 cm and the bearing capacity of rubber hose is increased to nearly 30,000 square meters.
(2) enhancement layer:

      4 layers of steel wire wound, the use of copper wire braided hose, bearing the work pressure is  3-4 times that of the ordinary hose, with a high degree of resistance, flexible  features own superior performance to enhance effect.The most reasonable formulation design is adopted to achieve the combination of rubber and steel wire.

  The tensile force of rubber hose steel wires has been tested and specially adjusted, which greatly strengthens the flexibility, pressure and explosion resistance of rubber hose.And it uses the latest environmental friendly adhesives in the world, which reduces pollution, increases the bonding strength of skeleton and rubber, and makes rubber hose more durable
.
(3) outside layer rubber:

Black, smooth (wrapped), SBR/NR compound.
Adding new anti-aging agent to the outer glue can make the rubber tube more anti-impact, anti-stretch, anti-aging and anti-ultraviolet, and improve the protective performance of the outer glue to the skeleton,which ensures all working conditions of rubber hose from 20 degrees below zero to 40 degrees above zero.
[material ] natural rubber and steel wire
(4)  The pipe head is made of seamless 37Mn5 steel pipe and quenched to make it more wearable.                       
      The tube core is made of 45Mn2 steel pipe and quenched to achieve high wear resistance.
       Appearance core is made of seamless steel tube and galvanized process, which makes it not only beautiful in appearance, but  it's also 100% hard to turn around.
