The Power of Nano-Coating: Revolutionizing Shower Screen Performance and Hygiene
Atomic Warfare: NanoQuartz’s Molecular Architecture
Covalent Bonding Mechanics
γSV=γSL+γLVcosθθNanoQuartz = 15∘ (superhydrophilic) → 148∘ (superhydrophobic)\gamma_{SV} = \gamma_{SL} + \gamma_{LV} \cos\theta \\ \theta_{\text{NanoQuartz}}\ =\ 15^{\circ}\,(superhydrophilic)\ \rightarrow\ 148^{\circ}\,(superhydrophobic)
Structural Profile:
Impact: Surface energy drops to 8-10 mN/m vs uncoated 72mN/m → transforms wettability physics.
