Water hose Model QA562

Water hose model QA562 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.
Therefore, first PVC pipes were used for sewage and then polyethylene for irrigation and water supply.
Stages of product production and raw materials for water hose production:

1- Mixing: Mixing of rubber composite materials is done in 2 stages. First, the raw materials and other additives are completely mixed. Then, by adding reinforcing agents, the mixing operation is done by a roller mill.

The resulting mixture passes through the cylinder in which the extruder coil is located and is heated by electrical elements, becomes the first layer of the hose.

3- Reinforcing fiber twister: Reinforcing fiber twisting operation is done by the fiber weaving machine around the first layer.

4- Extrusion of the second layer: 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 is packed by the collecting machine after washing, passing through the killer unit. When the product area is wrapped, it reaches a certain size and is cut to replace the hose roll.

Hose production process
First the materials are weighed and then by the extruder, the pressurized materials are melted and the melted materials are uniformly prepared for the production of hoses.
In the next step, the molten material enters the head, which is responsible for creating a uniform melt. The material then enters the main mold and the mold has the task of forming a uniform melt and turning it into a hose of a certain size.
In the next step, cool materials are produced and then by a hose calibrator with desired dimensions. The hoses produced in the calibration section are sufficiently cooled and the hose specifications are printed on it, and finally, the hoses are pulled by large pulleys.
Hose raw materials

Hoses are mainly made of different materials. Some hoses are even made of 8 different layers.

All these layers are made of a different material. The outer layer must be strong, because it stretches along the concrete and stone. PVC is often used for this outer layer.

In general, garden hoses are made of vinyl and rubber. The more durable the hose, the less it will leak.

The QA562 water hose is made of a material or a combination of different materials such as nylon, polyurethane, polyethylene, plywood, natural rubber or synthetic cement and blankets based on the environment and the pressure required.
