I. Core Application Environments: Corrosive Chemical Exposure Scenarios
Chemical Production and Processing
Scenarios: Reactor operations, material handling, and product packaging involving corrosive raw materials such as acids, alkalis, solvents, and oxidizing agents.
Risks: Chemical splashes, gas corrosion, and long-term exposure leading to oxidation of metal structures.
Protection Requirements: The protective suit must feature a fully enclosed design with PTFE (polytetrafluoroethylene) or PVDF (polyvinylidene fluoride) coatings to prevent liquid penetration.
Electroplating and Surface Treatment
Scenarios: Electroplating bath splashes, chemical polishing, and anodizing processes.
Risks: Corrosion of robot joints and sensors by acidic/alkaline solutions (e.g., sulfuric acid, sodium hydroxide).
Protection Requirements: The protective suit must resist splashes and have a smooth, easy-to-clean surface to prevent residue buildup.
Pharmaceutical and Biological Engineering
Scenarios: Active pharmaceutical ingredient synthesis, sterile formulation packaging, and fermenter cleaning.
Risks: Corrosion of robot casings and electronic components by organic solvents and acidic/alkaline cleaning agents.
Protection Requirements: The protective suit must use food-grade materials and combine chemical resistance with antimicrobial properties.
II. High-Risk Extended Scenarios
Marine Engineering and Salt Spray Environments
Scenarios: Offshore platform maintenance, ship painting, and underwater robot operations.
Risks: Galvanic corrosion of metals due to high salt and humidity levels.
Protection Requirements: The protective suit must use salt spray-resistant materials such as 316 stainless steel coatings or specialized anti-corrosion coatings.
Power and Energy Sectors
Scenarios: Battery manufacturing, electrolyzer maintenance, and nuclear power plant equipment inspections.
Risks: Electrolyte leaks and exposure to radioactive substances.
Protection Requirements: The protective suit must integrate radiation-resistant layers with acid/alkali-resistant films, such as lead composites.
Food Processing and Disinfection Environments
Scenarios: Meat processing, dairy production, and beverage filling line cleaning.
Risks: Corrosion from disinfectants such as sodium hypochlorite and peracetic acid.
Protection Requirements: The protective suit must resist low-concentration acids/alkalis and have a surface that is easy to clean to prevent microbial growth.
III. Key Considerations for User Selection
Type of Corrosive Substance: Identify the chemical composition and concentration of the medium (e.g., sulfuric acid > 30% requires specialized materials).
Exposure Frequency and Duration: High-intensity continuous exposure demands more durable materials, while intermittent contact may use replaceable protective modules.
Motion Flexibility Needs: Lightweight suits are essential for precision operations, whereas heavy-duty scenarios require a balance between wear resistance and rigidity.
Maintenance Costs: Disposable suits are suitable for highly contaminated environments, while washable types are ideal for long-term reuse.
Summary
Corrosion-resistant robot protective suits are essential equipment in industries such as chemicals, electroplating, pharmaceuticals, and marine engineering. Their core value lies in isolating robots from corrosive environments through materials science. Users should select products with appropriate chemical resistance ratings (e.g., ISO 12944 anti-corrosion standards) based on specific work conditions, robot motion requirements, and budget constraints to ensure production safety and equipment longevity.
