How to Consider Equipment Material Compatibility When Selecting Protective Products

Key Considerations for Equipment Material Compatibility

I. Chemical Compatibility Matching

Corrosion Protection Adaptation

Strong Acid Environments (pH ≤ 2): Prioritize PTFE linings or Hastelloy C276 protective coatings

Organic Solvent Environments: NBR gloves exhibit over 30% superior oil resistance compared to natural rubber

Electrochemical Isolation

Potential difference between contacting metals should ≤0.25V (e.g., copper-aluminum connections require insulating shims)

Protective coating resistivity recommended between 10⁶-10⁹ Ω·cm (for anti-static applications)

II. Physical Property Matching

Hardness Coordination

Hardness difference between friction pairs should be ≤20% (e.g., steel components paired with tungsten carbide coatings)

Soft protective layers (Shore A hardness 60-80) are suitable for scratch resistance in precision instruments

Thermal Expansion Matching

For high-temperature conditions (≥300°C), the difference in linear expansion coefficients should be <5×10⁻⁶/°C

Phase change materials (PCM) are suitable for environments with rapid temperature changes (-40°C to 150°C)

III. Typical Application Scenarios

Chemical Equipment Protection

316L stainless steel (Ra ≤ 0.8μm) withstands chloride ion corrosion

Titanium alloy TA2 passes 96-hour salt spray test

Electronic Equipment Protection

Anti-static shoe resistance: 10⁵–10⁹Ω (electronics workshops)

Conductive shoe resistance: <1 megohm (explosion-proof environments)

IV. Testing and Validation Methods

Laboratory Testing

Salt spray test (ASTM B117 standard ≥500 hours) verifies corrosion resistance

Thermal cycling test (-40°C to 85°C, 5 cycles) evaluates thermal stability

Field Validation

Contact resistance testing (compliant with IEC 61340 standard)

Actual operating condition wear rate monitoring (recommended <0.1mm/1000 hours)
