The Manufacturing Process of PVC Strip Curtains

The production of high-quality pvc strip curtains involves a precise, multi-stage process designed to ensure durability, clarity, and optimal performance in demanding industrial environments. The focus is on achieving consistent material properties and dimensional accuracy.

1. Material Selection and Preparation

• High-Grade PVC Resin: Selection of virgin PVC resin, often suspended in a liquid plasticizer, known for its inherent flexibility and chemical resistance. For low-temperature applications, specific plasticizers (e.g., DINP, DOP-free compounds) are chosen to maintain pliability in extreme cold.
• Additives Integration: Incorporation of various additives including UV stabilizers (to prevent degradation from sunlight), anti-fungal agents, flame retardants, and colorants (for tinted options). These are carefully blended to achieve desired performance characteristics.

2. Extrusion Process (Casting)

1. Melting and Homogenization: The prepared PVC compound is fed into a sophisticated extruder machine, where it is heated to a molten state and continuously mixed to ensure a uniform consistency.
2. Die Forming: The molten PVC is then forced through a precision die (often a slot die for flat strips) that shapes it into the desired strip dimensions (e.g., width and thickness). This step is critical for dimensional accuracy and surface finish.

3. Cooling and Solidification

• Water Bath/Cooling Rollers: Immediately after extrusion, the hot PVC strips are passed through a series of cooling rollers or a controlled water bath. This rapid and uniform cooling prevents distortion and sets the final physical properties of the material.

4. Cutting and Finishing

1. Precision Cutting: Once cooled and solidified, the continuous PVC sheet is precisely cut into individual strips of specified lengths using automated cutting machinery.
2. Edge Treatment (Optional): For specific applications, strip edges might be rounded or chamfered to enhance safety and prevent snagging.

5. Quality Control and Testing

Rigorous quality control measures are implemented throughout the process. Finished plastic strip curtains undergo a battery of tests to ensure compliance with industry standards:

• Dimensional Accuracy: Verification of width, thickness, and length.
• Material Properties: Testing for tensile strength (ASTM D882), tear resistance (ASTM D1004), hardness (Shore A D2240), light transmission, and low-temperature flexibility (ASTM D1790 for brittle point).
• Environmental Performance: UV resistance, flame retardancy (UL94 V-0 or similar), and chemical resistance.
• Compliance: Ensuring adherence to international standards such as ISO 9001 for quality management, and sometimes FDA compliance for food-grade applications.

Service Life: Properly manufactured and installed pvc strip curtains typically boast a service life of 3-7 years, depending on traffic volume, environmental conditions, and maintenance. Specialized formulations can extend this even further.
