Outline Green/Bio-Based Lubricants Pros/Cons Vanishing Oil Replacements V.O.C. Free Cost Effectiveness Real World Uses Case Studies Cost Savings Process Review
Green Lubricants Vegetable Seed Oils Steady Increase in Use Range of Applications Synthetic Technically Speaking Renewable Resource Bio-Based Free of Petroleum Oil
Green Lubricants Marine & Animal Based Growing Industry Range of Applications Easily Modified Expanded Use Synthetic Renewable Resource Bio-Based Free of Petroleum Oil
Initiatives & Regulations Supporting Bio-Based Lubricants 2009 California SCAQMD Rule 1144 2008 - California Bills 1879 & 509 2007 - Registration, Evaluation, and Authorization of Chemicals (REACH) 2002 - USDA BioPreferred 1999 - The Canadian Environmental Protection Act 1976 - Toxic Substance & Control Act (TSCA)
Bio-Based Defined U.S. Department of Agriculture Composition In Whole or Significant Percentage Consisting of: Plant Animal Marine
Bio-Based Defined Metalworking Lubricants - USDA Classifications Soluble, Semi-Synthetic, or Synthetic Contain Minimum 40% General Purpose 57% High Performance Straight Oil Products 66% Minimum Content
Bio-Based vs. Biodegradable Synonymous Bio-Based, Renewable Resource, Green Biodegradable Readily - Rapid & Complete Ultimately Additives/Ingredients Petroleum, Esters, Amines, Glycols, EP Additives
Bio-Based vs. Biodegradable Promote Environmental Benefits They Do Not Guarantee Safety Biodegradability Bio-Based Content Gain a Full Understanding
Benefits of Bio-Based Lubes Enhanced Lubricity Reduces Friction & Wear Lower Levels of Lubricity Additives Extreme Pressure Additives
Benefits of Bio-Based Lubes Higher Viscosity Index Stability over Temperature Range Petroleum Oil 40-75 VI Vegetable Based 200-250 VI Lower VI More Change in Viscosity at High & Low Temperatures Higher VI Less Change in Viscosity at High & Low Temperatures
Limiting Factors Thermal Instability Unstable at Higher Temperatures if Untreated Bio-Engineered Seeds Bio-Processing Technologies Oxidation Additives Antioxidants
Trends of Green Lubricants Straight Oils - Available for Many Years Recent Trend Water Extendible Fluids Reduced Friction Greater Wear Resistance Reducing Extreme Pressure Additives
What does it all mean? Lower Overall Coefficient of Friction Easier to Clean Parts Lower Washer Temperatures Lower Cleaner Concentrations Better Rust Protection Better Weld Through Lower Costs
Pure Renewable Exclusive Use of Renewable Resources Remove the Extreme Pressure Additives Chlorine, Phosphorous, Sulfur Rely Wholly on Boundary Film Lubrication Soybean Based Lubricants
Green Lubricants Demand on Foreign Oil Lessens US Farmers Contribute to Industrial Engine Performance Characteristics Less Toxic to Environment Easier to Dispose Lessened Health Risks
Vanishing Oil Replacements
Many Varieties - Many Names Disappearing Compounds Vanishing Oils Evaporatives Solvents Numerous Operations Drawing, Forming, Punching, Perforating Leave a Clean Dry Part
What is a Vanishing Oil? Carrier Petroleum Distillate Evaporates Controls Drying Time Lubricity Additives Wetting Boundary Film Lubrication Extreme Pressure Additives Corrosion Inhibitors Metal Passivators
Residues Dependant on Additives Dry to the Touch Oily Sticky Non-Existent
Application Methods Drip, Spray, Roller Caution to use only Airless Sprayers Heat Generated in Operation Facilitate Drying Too Little Applied Evaporate before Operation Completed Galling or Tool Wear Too Much Applied Wet Parts Packing Wet Drying Time Effected
Categorizing Flash Point Lowest Temperature at which enough vapors to ignite if ignition source. 105ºF, 125ºF, and 140ºF Lower Flash = Faster Drying Flammability Rating: 2 Drying Time <20 minutes to hours
Speeding Up the Drying Influence Evaporation Rate Heat from Process Fans Heat Tunnels Air Knives Enough Lube to do the Job More is Not Better
V.O.C. Issues Vanishing Oils High Level of V.O.C. s Volatile Organic Compounds React with Nitrogen Oxides (NOx) Ground Level Ozone Smog EPA & Clean Air Act Non-Attainment Areas Reduce Emissions Eliminate
V.O.C. Regulations National Clean Air Regulatory Agenda (CARA) & Regulatory Framework for Air Emissions Reduce Emissions of VOC s Regulations to limit VOC Concentrations Aligning VOC Concentration Limits in Cooperation with United States Source www.canada.gc.ca
Complying with Regulations Pursue Necessary Permits Use Oil & Wash Parts Scrubbing Systems Incineration Carbon-Adsorption Technology Switch to Better Chemistry????
V.O.C. Free Alternative Water Extendible Synthetic Fluids Mimic Benefits of Solvent-Based Fluids Wetting Lubricity Drying Time Need to Evaluate Water Source All water is not the same
Water - Knowledge Type of Water Soft or Hard (Calcium and Magnesium) Treated Water Reverse Osmosis, Deionized, Softened Microbial Growth Staining, Spotting, Rusting
Latest Technology V.O.C. Free Vanishing Fluids Green Fluid Technology Direct Replacement for Solvent Based Lubricants No V.O.C. permits or fees required
Green Fluid Technology HMIS Rating Comparison Typical Vanishing Oil Health - 1 Flammability - 2 Reactivity - 0 ACGIH TLV - 100 ppm OSHA PEL - 100 ppm VOC Free Vanishing Fluid Health - 0 Flammability - 0 Reactivity - 0 ACGIH TLV n/a OSHA PEL n/a ACGIH TLV Threshold Limit Values - Guidelines in making decisions regarding safe levels of exposure to various chemical substances. Health based values OSHA PEL Enforceable Permissible Exposure Limits protect against exposure to hazardous substances. Based on 8 hour time weighted average
Green Fluid Technology No Special Ventilation Required Normally Dries Twice as Fast Does not Contain Chlorine, Sulfur or Phosphorus Excellent Corrosion Protection High Lubricity Factor All Metal Safe Odorless
Case Studies
Vanishing Oil Support Brackets G30 G90 Galvanized Progressive Die Airless Spray System Parts go direct to Assembly Current Lube Petroleum Based Vanishing Oil Used as Supplied Goals Eliminate White Rust on Parts Eliminate Smell of Current Vanishing Oil
Water Extendible Synthetic Run at 9:1 Ratio / 10% Solution No White Rust in Over 6 months of use Some parts stacked flat Reduced Smell Issue Eliminated V.O.C. s from Plant Non-Flammable Overwhelming Acceptance
Switch to a Greener Fluid HSLA.075 -.090 thick Multiple Draws Tough Part Tool Life Concerns Parts Deburred Prior to Assembly Using Chlorinated Soluble Oil @ 7:1 Tough to Clean Short Term Rust Protection - Suspect
Switch to a Greener Fluid Switched to a Vegetable Based Soluble Oil @ 7:1 Reduced Chlorinated Paraffins by half Easier to Clean Obtained desired Rust Protection No change in Tool Life Cost Savings 0.25 Lubricants 0.20 0.15 Cleaning Coefficient of Friction 0.10 0.05 Chlorinated Solube Oil Bio-Based Soluble Oil 0.00 0 10 20 30 40 50 60 Time (seconds)
