Manufacturing Process Flow for PVC Strip Curtains

The production of high-quality pvc strip involves a precise and controlled manufacturing process to ensure material consistency, durability, and performance. The primary method utilized is calendering or extrusion.

Key Process Steps:

1. 1. Raw Material Preparation:

   High-grade Polyvinyl Chloride (PVC) resin is combined with various additives. These typically include:

   • Plasticizers: To achieve flexibility and desired softness (e.g., DINP, DOTP).
   • Stabilizers: To prevent degradation from heat and UV light during processing and service life (e.g., Calcium-Zinc stabilizers for lead-free products).
   • Colorants: For specific visual requirements, such as the distinctive orange in anti-insect variants or opaque welding screens.
   • Lubricants: To aid processing.
   • Performance Enhancers: Anti-static agents, flame retardants, or anti-insect compounds (e.g., citronella essence for anti-insect variants).
2. 2. Compounding and Mixing:

   The raw materials are precisely weighed and blended in high-speed mixers to create a homogeneous compound. This ensures uniform properties throughout the final product.

3. 3. Melting and Plasticization:

   The PVC compound is fed into an extruder or calender. Under controlled heat and shear, the compound melts and becomes a viscous, molten plastic mass.

4. 4. Extrusion or Calendering:

   Extrusion: The molten PVC is forced through a die to form continuous pvc stripes of specified width and thickness. For ribbed strips, the die design incorporates the rib profile.

   Calendering: The molten PVC is passed through a series of heated rollers (calender rolls) that gradually form it into a continuous sheet of the desired thickness. Individual strips are then cut from this sheet. This method often produces a very smooth surface finish.

5. 5. Cooling and Stabilization:

   The extruded or calendered PVC strips are then passed through cooling baths, typically with water, to rapidly solidify the material and prevent deformation. Controlled cooling ensures dimensional stability.

6. 6. Cutting and Winding:

   The continuous strips are cut to specified lengths or wound into pvc strip rolls. Quality checks are performed for dimensions, visual defects, and material integrity.

7. 7. Quality Control and Packaging:

   Each batch undergoes rigorous testing to ensure compliance with relevant standards such as ISO 9001 for quality management, and potentially specific material performance standards for fire rating (e.g., DIN 4102-B1), temperature resistance (e.g., ASTM D746), and toxicity (e.g., FDA for food contact, REACH/RoHS for chemical compliance). Products are then packaged for shipment.

Service Life and Target Industries:

The typical service life of plastic strip curtains ranges from 3 to 10 years, depending on traffic volume, environmental conditions (UV exposure, temperature extremes), and proper maintenance. Heavy-duty ribbed variants often last longer due to their increased surface area and impact resistance.

Target industries include:

• Food Processing & Cold Storage: Energy saving, insect control, hygiene maintenance (e.g., FDA-compliant materials).
• Warehousing & Logistics: Temperature zoning, dust reduction, efficient traffic flow.
• Manufacturing Facilities: Noise reduction, separation of production zones, dust and fume containment.
