QA352 water hose
QA352 water hose
The QA352 water hose has a cylindrical shape and its cross-section is circular.
In the design and construction of a water hose, such things as function, size, tolerable pressure, weight, length and دارند all play an important role.
After the discovery and application of polymers, especially plastics, due to the resistance of these materials to corrosion, industries sought to replace these materials with metals.
Stages of product production and raw materials for water hose production: 
1- Mixing: Mixing of rubber composite materials is done in 2 steps. First, the raw materials and other additives are completely mixed. Then, by adding reinforcing agents, the mixing operation is done by a roller mill.
2- The resulting mixture becomes the first layer of the hose by passing through the cylinder in which the extruder screw is located and is heated by electrical elements.
3- Reinforcing fiber twister: Reinforcing fiber twisting operation is done by the fiber weaving machine around the first layer.
4- Second layer extrusion: The first layer is fed to the second extruder after wrapping the reinforcing fibers. The second layer of hose is formed by leaving the extruder 5- Screw roll: The final product, after washing, passing through the killer unit, is packed by the collecting machine. When the product area was wrapped, it reached a certain size to replace the cut hose roll.
