How to make PVC lay flat discharge hose?
Making a PVC lay flat discharge hose involves several steps, including material selection, extrusion, reinforcement, curing, and quality control. Here is a detailed overview of the process:
1. Material Selection
The primary materials used are:
Polyvinyl Chloride (PVC) Resin: The main material for the hose.
Plasticizers: To make the PVC flexible.
Stabilizers: To enhance the durability and heat resistance of the hose.
Colorants: To add the desired color to the hose.
Polyester Yarn: For reinforcement, providing strength and flexibility.
2. Extrusion of the Inner Layer
The process begins with the extrusion of the inner PVC layer:
Mixing: PVC resin, plasticizers, stabilizers, and colorants are mixed to create a homogenous compound.
Extrusion: The mixed compound is fed into an extruder, which heats and shapes the PVC into a tube. This forms the inner layer of the hose.
3. Reinforcement
The next step is to reinforce the PVC tube with polyester yarn:
Braiding or Knitting: The extruded PVC tube is passed through a braiding or knitting machine that wraps polyester yarn around the tube. This reinforcement provides additional strength and prevents the hose from bursting under pressure.
4. Extrusion of the Outer Layer
After reinforcement, the outer layer of PVC is applied:
Second Extrusion: The reinforced tube is fed through another extruder that applies an outer layer of PVC, encapsulating the polyester yarn. This outer layer protects the reinforcement and provides durability.
5. Curing
The extruded and reinforced hose needs to be cured to ensure the PVC layers bond properly:
Heating: The hose is passed through an oven or curing chamber where it is heated to a specific temperature. This process ensures that the inner and outer PVC layers fuse together with the reinforcement, creating a strong, cohesive hose structure.
6. Cooling
After curing, the hose is cooled to solidify the PVC and stabilize its shape:
Water Bath: The hose is typically passed through a water bath to cool it rapidly and set its dimensions.
7. Quality Control
The final step is to inspect and test the hose to ensure it meets quality standards:
Visual Inspection: The hose is checked for any surface defects, inconsistencies, or irregularities.
Pressure Testing: The hose is subjected to pressure tests to verify it can withstand the specified working and burst pressures.
Dimensional Checks: The hose’s diameter, thickness, and length are measured to ensure they meet the required specifications.
8. Cutting and Packaging
Once the hose passes quality control, it is cut to the desired lengths and prepared for packaging:
Cutting: The hose is cut into standard or custom lengths as required by the customers.
Fittings: Quick-connect fittings or camlock couplings may be attached if specified.
Packaging: The hose is coiled, strapped, and packaged for shipment.
Summary
The manufacturing process of PVC lay flat discharge hoses involves a series of steps to ensure the hose is durable, flexible, and capable of handling various pressures and conditions. By selecting high-quality materials and adhering to strict manufacturing standards, manufacturers produce hoses that meet the diverse needs of agricultural, construction, industrial, and emergency applications.
