Conclusions: Solvents, including terpenes, soy oils and diesel fuel, should not be used to clean rubberized belts. It is noted that the higher the solvency (measured by Kauri Butanol Point - KB) of the chemical, the greater the degradation of the belt.

Both aliphatic and aromatic solvents significantly shorten belt life when these solvents are used to clean on a continuing basis.

Standard additives and surfactants when compounded in lubricants do little or no harm to rubberized belts.

Tec-Shield and its components do little or no harm to rubber components. By preventing asphalt cement (aliphatic & aromatic hydrocarbons) from repeatedly sticking to rubberized surfaces, Tec-Shield will protect and extend the life of the rubber component.

Notes:


MEA: Monoethanolamine


TEA: Triethanolamine


AMP: Amino Methyl Propanol (Replacement for Diethanolamine)

Isopar M: Exxon's odorless, isoparafinic, aliphatic hydrocarbon solvent (low odor, low solvency, KB @ 23)

D'Limonene: Orange terpene solvent, high solvency (KB @ 55)

Tergitol 15-S-9: Linear alcohol ethoxylate (Surfactant)

KSI-03-048G: Experimental blend surfactants & additives

Sasol 181: High solvency (KB @ 72) aliphatic solvent from natural gas produced by South African
firm, Sasol.

1.00. No change in volume or weight relative to the water sample.
1.01 - 2.00. Minimal change, slight weight gain from pore space filling on cut edges, surface develops slight tacky feel, but generally remains rigid and impenetrable.
2.01 - 4.00. Moderate change, weight gain significant with discoloration of surrounding liquid, cut edges become pliable with overall significant swelling.
4.01 - 8.00. Substantial damage, weight gain exceeds 50% of original value, volume measurements difficult due to curling at edges and increasingly warped surfaces.
8.01 - 16.00. Severe damage, sample is soft, penetrable, and very pliable, cord may be frayed and loosening, overall sample is very warped and curled.

Effect of Various Chemicals on Rubberized Belt (November 1999)


Individual chips (samples) of the belt furnished by a Major Asphalt Equipment Manufacturer are emerged in various solvents, oils, and additives for a long-term study to determine potential degradation of the belt by these chemicals. One hundred & thirty (130) days of data are described.


Summary Conclusions


Solvents, including terpenes, soy oils and diesel fuel, significantly shorten belt life when these chemicals are used to clean repeatedly. The higher the solvency, measured by Kauri Butanol Point, the greater the degradation of the belt.


Tec-Shield and its components do little or no harm and, in fact, Tec-Shield protects and preserves the life of belts and other rubber components, ( Hydraulic Hoses, Bumpers, Rubber Tracking, Rubber Tires and the like), from the solvency of asphalt cement itself, when allowed repeatedly to stick.

Eliminates the possibility of fume ignition. Biodegradable and VOC exempt. Costs less to use than diesel fuel.

Eight-Conveyor Explosions and Plant Operator Injuries Reported


Using diesel fuel as a slat conveyor cleaner in asphalt plant operations is an old habit. Eight- conveyor systems across the country have exploded due to sparks igniting trapped diesel fuel vapors. The practice of using diesel fuel for cleaning enclosed conveyor systems is risky. Enclosing slat conveyor systems is intended to reduce the risk of someone falling into the moving slats, and to contain "blue smoke"emissions. The problem is, the enclosures also trap diesel fuel and asphalt fumes. This creates the risk. 

Sparks, caused by static electricity or a stone striking a metal component, ignite the fumes. Explosions can be severe, twisting metal and hurling panels hundreds of feet away. Workers in the way are injured.

Diesel fuel is a fuel; it was never designed to be a solvent cleaner. It is toxic and volatile, constantly changing from liquid to a gas and faster at higher temperatures. The diesel fuel flashpoint commonly ranges from 100 to 120 (F) degrees. Temperatures within a conveyor system can easily exceed 300 (F) degrees.
Solution: For years many of our customer contractors (asphalt producers) have substituted our products Teclon-50 or Tec-Shield, for diesel fuel. They used our synthetic oil technology to lubricate and maintain their slat conveyors. They recognized the risks described above for some doing Storm Water Sampling and Reporting, they did not want the added danger of diesel getting into their water table. An additional payoff for customers using Teclon 50 or Tec-Shield is reduced amperage needed to drive the system. Some reported as much as a ten percent savings in electricity. Because of our synthetic technology system, rough and jumpy starts are eliminated, with a concomitant reduction in wear.
Tec-Shield is diluted with water. We recommend 15 to 1 dilution rate for conveyors. The savings are real.

Dispensing: We provide at cost a drum-mounted dispenser/proportioner system to appropriately dilute Tec-Shield when filling various containers. Tips or plugs are provided for insertion in the system to provide alternative dilution rates.


From a central location use the dispenser/proportioner to fill 5-gallon soak buckets or 2 or 3 gallon Hudson pump-up sprayers. These sprayers are for use by crews at lay-down sites. For example, if your city or county has 6-5 man crews, each crew might take to the job site a 5-gallon soak bucket and 3 sprayers for use in spraying down a paver or drag box. Water might not be immediately available at the job site. It's better to let the drum mounted dispenser do the mixing and filling each day and avoid delays. Our heavy-duty dispenser/proportioner will fill containers at a rate of 4 gallons per minute with Normal City water pressure. It can save a lot of work and time . Separate written instructions for setting up the dispenser are provided. You can call for help in set-up also.


An alternative is to use a clean, empty drum to dilute and dispense Tec-Shield. Put six gallons of undiluted Tec-Shield in the drum and then fill it with water. You might have to help mixing of the product. You can do this by filling the drum using as much water pressure as is available, and also by inserting a compressed air hose to the bottom of the drum and let the air circulate the Tec-Shield and water until they are completely mixed.


Keep shovels and lutes hot and retreat them with Tec-Shield before asphalt starts sticking again. (You will get sticking occurring always about a half of an inch around the outside of the shovel blade.) Treat all tools before hanging them up. This is whether there is a break in shoveling requirements or at the end of the day. Soaking shovels in Tec-Shield is of no purpose. Tec-Shield is not a solvent. Become a hero to your crews; slay the Scary Monster!

Particularly with dry mixes, once the shovel is clean, you will get 25 to 45 shovel strokes in asphalt before sticking occurs and retreatment with Tec-Shield is needed. (With diesel fuel, you get only 4 to 8 strokes of the shovel before asphalt starts sticking again.) Wet, oily mixes are the toughest to deal with for both diesel fuel and Tec-Shield.

What are the procedures to maintaining clean tools? First dip (or spray) the shovel blade (or the lute) into diluted Tec-Shield. Next immerse the shovel blade into hot mix for about 15 seconds to heat the shovel. Jerk the shovel back and forth in the hot asphalt to begin the cleaning process. Next, use a putty knife or your boot to scrape the heated and soft asphalt from both sides of the blade. You may need to repeat this procedure a few times to get the shovel thoroughly cleaned and Tec-Shield lubricants plated into the metal.


Tools: These instructions apply to lutes as well as shovels. First, throw out the diesel fuel (legally please) and put an 8 to 1 dilution (water to concentrate) solution of Tec-Shield (about 3 gallons) in the ol' diesel bucket. You can go to 10 to 1 in the second week. Next, don't be afraid of the Scary Monster called "change." Get it out of your mind that Tec-Shield will work like diesel fuel. It won't! Diesel is a solvent, toxic too, and the state DOT's will not approve a solvent replacement. Solvent strips asphalt. Tec-Shield is not a solvent and works differently. It contains high temperature lubricants (600 to 800 degrees Fahrenheit boiling range), which cannot be cooked off by the 300-degree temperatures of hot mix. Then it plates out on metal and rubber surfaces, preventing asphalt from sticking. "Heat" - the temperatures of hot mix at lay down - is the only other ingredient required for the success of Tec-Shield in replacing diesel fuel. Of course you will need hand spray bottles filled with Tec-Shield and putty knives for each crewmember's use.

Tip #1:Before moving the vehicle onto fresh mat, warm and condition tires by continuous spray down with Tec-Shield, while moving the vehicle back and forth on old pavement.


Tip #2: When first moving on to fresh mat, spray tires continuously while driving the length of the compaction job completed by the paving crew so far.


Tip #3: After the initial 1 treatment described above, spray tires periodically, and at least two or three revolutions before stopping or reversing direction. "Stop and Go" equals "Pick-Up" usually.


Tip #4: Generally, once tires are created and hot, little more treatment is needed. Economics of 15 or 20 to one dilution rates are possible and practical with base stock asphalts.

Rubber Tire Rollers (Steel Drum or Vibratory):Problem: If the DOT inspector rejects your 'laydown' because of "asphalt pick-up" by rubber tire compaction, we have a solution.


See the tips: on the right for your driver to try, while he or she develops their own techniques. Reason: the great variety of mix designs, raw materials and weather conditions confronting the compaction job require the professional judgment of skilled operators for success.


Tec-Shield:Dilute the concentrate with ten parts water and fill the spray tank on the vehicle with diluted product.

Material Transfer Vehicles: Using an 8 to 1 solution, (water / Tec-Shield Concentrate), spray all Hopper / Bar & Chain Assemblies / Compartments at least three times daily.  Also spray down whenever laydown is interrupted or a cool down is expected.


Pavers: Spray all components of the paver at least three times daily. Also, spray whenever lay down is interrupted and cool down is expected. 

Instructions for Using Tec-Shield:General: If you're replacing diesel fuel, just remember that diesel is primarily a solvent. It dissolves and cleans asphalt off of tools and equipment, and has done this since the late 1800's. Tec-Shield is not a solvent. It provides a lubricant shield on metal surfaces, preventing asphalt from sticking in the first place.


Leadership: These instructions are based on the experience of workers, crew chiefs and superintendents in the HMA industry. They have successfully dealt with the myriad of situations found at lay-down sites, and stopped using diesel completely. Now they are using Tec-Shield exclusively. You can expect complaints initially. Change in work habits is not easy. 

THE MAGIC WORD In the Hot Mix Asphalt Industry is YES!


Finally, there is a product that works and can replace the use of diesel fuel for asphalt cleaning and lubrication at the lay-down site. 
It is called TEC-SHIELD

Tec-Shield

Tec-Shield is a synthetic lubricant with minimal solvent properties in concentrated form. It is developed to replace the use of diesel fuel as a cleaner in hot mix asphalt operations. It is applied at a minimum dilution rate of eight parts water to one part concentrate to prevent asphalt from sticking to metal and rubberized surfaces of asphalt equipment and tools. It then provides high temperature lubrication and heat and corrosion protection to asphalt laydown equipment.
