Combating Cleaning Agent Corrosion: How SYSTEM’s Screen Chemical Protective Layer Passes 5,000 Wipe Tests

1. The Hidden Threat in Fitness Facilities: Chemical Corrosion of Screens

In 2024, a premium Beijing gym faced operational crisis due to widespread screen failures – sticky coatings and surface cracking emerged across 30 body composition analyzers within six months under daily chlorine-based disinfection (5 wipes/day). Laboratory analysis revealed:

• Sodium hypochlorite (0.1% concentration) decomposed polyurethane protective films

• Alcohol solvents penetrated ITO conductive layers, increasing circuit impedance (>300Ω/sq)

Three corrosion mechanisms drive this degradation:

1. Chemical Bond Cleavage: Oxidants break polymer chains, forming sticky oligomers

2. Swelling Effect: Ethanol induces 12% coating expansion, accelerating micro-crack propagation

3. Electrochemical Corrosion: Electrolyte infiltration triggers ion migration between electrodes (Fig.1)

Industry data shows gym screen replacement cycles average only 1.8 years (67% shorter than industrial equipment), generating maintenance costs up to 45% of initial procurement expenses annually.

2. Military-Grade Protection Transformed: Nano-Coating + 9H Hardness Dual Defense

SYSTEM adapts spacecraft fuel tank anticorrosion technology through molecular-level structural engineering:

Core Technology 1: Gradient Nano-Coating – Chemical Inertia Barrier

Utilizing Plasma-Enhanced Chemical Vapor Deposition (PECVD), we implement triple-layer coating:

• Base Layer: 50nm SiO₂ enhances adhesion (ASTM 5B rating)

• Functional Layer: Fluorine-doped TiO₂ nanocrystals (10nm grain size) creates hydrophobic/oleophobic surface (115° contact angle)

• Protective Layer: Diamond-Like Carbon (DLC) blocks acid/alkali penetration

SGS verification confirms 8× resistance to pH1-13 chemicals and >95% transmittance after 5,000 alcohol wipes.

Core Technology 2: Mohs 9H Hardness – Physical Defense Matrix

Ion beam surface hardening combats mechanical abrasion:

1. Argon ion bombardment increases surface density to 2.8g/cm³

2. Nano-alumina particles (20nm) form micro-ceramic networks

3. Achieves Mohs hardness 9 (resists #0000 steel wool abrasion)

Table 1: Protective Layer Performance Comparison

Parameter	SYSTEM Coating	Industry Standard
Alcohol Wipe Resistance	>5,000 cycles	800 cycles
NaOCl Resistance	300 hours	40 hours
Pencil Hardness	9H	3H
Transmittance Loss	<2%	>15%

3. Demonstrated Value: 3× Lifespan Extension & Maintenance Revolution

Field validation across 200 Wills Fitness locations reveals transformative performance:

Scenario 1: High-Disinfectant Environment (Shanghai Pudong)

• Daily disinfection: 8 times

• After 12 months:

  • Coating integrity: 98.7%

  • ΔFriction coefficient: 0.02 (initial 0.15)

  • Maintenance cost reduction: 52% YoY

Scenario 2: High-Humidity Environment (Guangzhou Tianhe)

• Ambient humidity: >75% RH

• Corrosion current: <0.3μA/cm² (safe threshold: 5μA/cm²)

• Zero failures in 18 months

Economic Impact (per 20-device facility):

• Conventional screens: Annual replacement cost ¥84,000

• SYSTEM solution: Annual replacement cost ¥16,000

• ROI period: <5 months

4. Technology Expansion: Redefining Public Display Durability Standards

SYSTEM's chemical protection technology establishes new industry paradigms:

As noted by Dr. Li Feng of Ningbo Institute of Materials Technology and Engineering (CAS): "SYSTEM’s F-doped TiO₂ coating creates a 'maze effect' for corrosive media migration, marking a milestone in flexible electronics protection."

This technology extends to medical devices, POS terminals, and public touchscreens. When disinfectant sprays fall in gyms, SYSTEM screens maintain pristine surfaces – a triumph of materials science meeting public health and digital experience demands.

Technical Specifications:

• Chemical Protection Rating: IP6X (dust)/IPX5 (water) enhanced

• Wipe Durability: 5,000 cycles (GB/T 9274-88 standard)

• Environmental Tolerance: -30~85℃ • 5~95% RH
