SPC flooring may deform during use, affecting both appearance and longevity. To ensure stability and durability, strict control is required throughout production, processing, and installation. The following are key preventive measures:
Key point: Die lip gap adjustment.
For 4 mm SPC products, the die lip gap should be precisely set at 4.2–4.5 mm. Also, maintain the correct production speed ratio to prevent deformation caused by improper parameter settings.
CPE (chlorinated polyethylene) enhances floor toughness but must be used appropriately. Excessive CPE can cause deformation – reduce the amount moderately without affecting product quality.
Excessive heat during UV treatment can induce thermal stress and deformation. Solution: Install a water-cooling device on the UV line and regularly check equipment to prevent abnormal temperature rises.
Avoid over-pressing edges during slotting to prevent stress concentration. Use suitable pressure and precise techniques to ensure smooth slotting without local extrusion damage.
Temperature fluctuations can cause deformation because the wear layer and the base material shrink at different rates, so it is essential to strictly control the tempering temperature and duration to prevent structural distortion from overheating.
Follow two essential principles during installation:
These measures, combined with adjustments based on actual conditions and regular maintenance, effectively reduce SPC flooring deformation and ensure long-lasting appearance and durability.
