The core requirements of windproof roller blinds and PVC door blinds

Application Scenarios: Core Requirements for Windproof Roller Screens and PVC Strip Curtains

Outdoor Applications of Windproof Roller Screens
High-Strength Welding: The Puxiong welding machine can weld sunlight-resistant fabric or PVC materials in lengths of 6-7 meters in a single operation, meeting the dimensional demands of large-scale windproof screens. The welded curtain and zipper form an integrated unit. Combined with chain-cutting devices and weighted designs within the side rails, the system maintains stable operation even when installed on sloped architectural surfaces (≤10°).

Sealing Optimization: Heat-sealing technology eliminates needle holes inherent in traditional sewing methods. Paired with overlapping or magnetic designs, air-tightness is significantly enhanced. For instance, welded PVC strip curtains in cold storage facilities or food processing plants can reduce energy consumption by 50% while blocking dust and odors.

Industrial Requirements for PVC Strip Curtains
Fire Resistance & UV Protection: Flame-retardant materials or UV-filtering layers can be integrated with zippers via thermal bonding, meeting fire safety standards for chemical plants and laboratories, or blocking harmful light waves.

Weather Resistance & Durability: PVC material remains flexible even at -70°C. Welded curtains withstand extreme temperature fluctuations and offer a service life exceeding 5 years (with twice-daily operation). Maintenance cycles are extended to quarterly track cleaning and annual lubrication.
