Winter is Coming! Are You Ready?

23 Oct, 2017

I have worked in the Tire Fill Industry for more than 25 years. Each year, a Cold Weather Bulletin is distributed stating that TyrFil™ Flatproofing must be at 72° F before processing. But every year, I have seen the same old problems caused by TyrFil stored and processed at too cold of temperatures. I am going to list a few common problems and the preventive actions for you to take during the colder months, but the TyrFil processor is the main person that can prevent cold weather problems.

Cold Weather Preventative Maintenance Checklist

1. Order TyrFil earlier than usual. Our products are shipped from Cleveland, OH and Chattanooga, TN. TyrFil needs to be at least 72° F for processing. If you receive a tote from Cleveland, its temperature could be 32° F or below and it would take 3-4 days at 72° F for TyrFil to warm up to the correct processing temperature.

2. Store TOTES inside, if possible.

3. If possible, the TOTES that are hooked up to the pumping system should be on a rack or even stacked on top of a couple pallets so heat can circulate around them. Since heat rises, the floor is always the coldest area of the room.

4. Keep everything warm! Buy a THERMOMETER so you will not have to guess the temperature.

5. TIRES need to be pre-stretched. Warm tires will stretch easier. Also, warmth speeds the cure time, so keeping the tires warm before and after filling will help. One tip is to put processed tires on a pallet so they will be off of the cold floor. Another tip would be to keep tires an extra day to ensure they are cured properly to avoid flat-spotting and to obtain optimum physical properties.

6. Viscosity is a measure of a fluids resistance to flow! Temperature is the kryptonite to viscosity. The NUMBER ONE problem is BAD MIX! When you try to pump cold material, the material can get off ratio and fail to reach the physical properties that they are designed to reach, resulting in potential product failure.

7. Pumping TyrFil below 72° F will slow down the filling process (especially pumping through a long valve stem) because of the higher viscosity of cold material, and this will cost your company money due to the extra time it will take to process tires.

8. The thicker viscosity of cold material can add extra pressure on the seals in your pumping system and can cause them to blow which can be a costly repair.

9. If you have a Graco or 7200 pumping system, keeping the ambient temperature around 72° F helps prevent the air motor from freezing. This is caused from moisture in the air lines and when air is compressed and released quickly, it creates a cooling effect. When freezing happens, it can damage O-rings inside the air motor and result in downtime for repair.

10. If you have a Green Machine or AutoFil Machine, cold grind can slow down the filling process. Remember to keep everything warm that pertains to the filling process.

Tech Tip: Tire Fill Recycling and replenishing with the Green Machine

12 May, 2014

by Matt Perhacs, ArncoPathway Tech Supervisor, OEM & International

When filling tires with the Green Machine, it is not uncommon for the material in the mixer to unexpectedly run low. This can happen due to the ground urethane (grind) running out or the cavity pump system being run too quickly for the amount of incoming material. This can cause unwanted air pockets to be injected into the tire.

To prevent this issue, or in the case that it has already begun to happen, the following is a quick, easy trick to replenish the material in the mixer and prevent any additional air from entering your filled tire.

1. If using an air water valve and with the machine stopped, push down the plunger on the fluid gun and begin to thread the valve core in just enough to hold the plunger in place. This will prevent any additional air and material from entering the tire during the next step.

If using the Green Machine’s pipe or needle injector valve, simply close the ball valve.

2. Next, open the drain valve on the material line just beyond the progressive cavity pump and place a waste container underneath.

3. Run the system on your desired mix setting, making sure that your cavity pump speed is not too high.

4. Your green machine will now pump out any trapped air through your drain valve, and fill the mixer back up to an adequate level with material.

5. Once this is done, stop the machine, close the drain valve and remove the valve core from the tire valve once again or, open the necessary ball valve if applicable.

You can now start your machine and have the proper amount of material flowing without any additional air entering your filled tire.

 

Tech Tip: Proper Tire Flatproofing Pressurization

7 Sep, 2012

Proper pressurization during the polyfill process is essential to ride, wear, and longevity of the tire.

Preparation
Your Manager or Salesman brings you a tire and says “fill it”. As a Certified Polyfill Processor the first question to ask is:

When do you expect it back?

Most likely you will hear in that familiar voice “I need it Yesterday”

This is when you get that rare opportunity to throw the ball back in their court by respectfully remind them the tire needs to stretch for 24 hours at max psi before processing. After you get that look, you know the one, the next question to ask is:

What pressure should the tire be filled?

Because proper pressurization critical to the performance of the tire and fill, the salesman should ask the customer questions based on this criteria.

Factors to Consider When Determining PSI

  • The weight of the equipment including total weight of the fill
  • The Maximum load carried
  • The max speed and distance in the application
  • Tire size and ply rating

Add the total equipment weight and maximum carried load. Pressurize to the Manufacturers recommended psi based on the total weight & tire ply rating. Note Application Exceptions: high pressure e.g. extended boom, underground mining. Max tire pressure should be used.

ecofil should be max tire pressure + 10%

Tech Tip – Cold Weather Changes Tire Flatproofing Cure Times

4 Sep, 2012

The Golden Rules Is To Keep Everything Warm!
This includes the tires and wheels. 80% of the problems reported during winter are linked to low temperature curing conditions.

Buy a thermometer and measure temperatures.
Be sure the material is at least 72°F before filling the tires. The average shop temperature during the winter is about 55°F. At this temperature, a minimum of 4 days curing time is required (see chart below).

Order ahead.
Don’t wait until you run out. Material gets cold during shipping. Ordering ahead of time will ensure that your material will arrive and have time to reach room temperature. Newly received material needs to warm up. Cold material placed in a warm room may require several days to reach the proper temperature. Also, cold material is thick, slow to pump and will not blend properly because of the drop in velocity through the mixing tube. Turning up the heat during processing will not heat the material quick enough.

Keep the flatproofed tires warm during the curing cycle.
Again, a temperature of 72 °F is necessary for curing. In order for the samples to be accurate they must stay with the tires. Check the samples daily and note their progress. Careful control of temperature will minimize cold weather flatproofing problems. Without a sufficient cure, you can’t be confident of the tire’s performance. The warmer – the better

 

Tech Tip – Maintaining proper pressure gauges on Graco Pump

4 Sep, 2012

Learning to correctly read and understand the pressure gauges is a very important part of being an Arnco flatproofing technician. We will focus on the 0 to 1000 psi high pressure gauges located on the A & B cylinders of the flushLess pump.

The pressure gauges measure the amount of fluid pressure each cylinder generates as it pushes the polymer through the hose to the FlushLess manifold. The normal pressure reading is between 200-400 psi with an intake air pressure of 80 psi. It is important to note that a higher air regulator setting will increase the cylinder pressure readings.

The gauges should be observed during pump operation. They should operate in a synchronous motion. A difference of 50 to 75 psi between the A & B gauges is considered normal as the A-side material is heavier than the B-side material. Any pressure reading under 200 psi is an indication of worn or leaking seals. If gauge readings are behaving in an opposite manner (example: the A-side gauge has a high reading while the B-side gauge reads zero pressure), a malfunctioning cylinder ball check or faulty manifold check valve is probably the cause. An off ratio mix may occur if the pump is operated in this condition. Replacement OEM seal kits are available through Arnco as well as a parts exchange program for all of Arnco’s customers.

 

Tech Tip: Removing a wheel from its foam fill

4 Sep, 2012

Tire Removal Instructions
This technical bulletin will address tire removal and wheel salvaging from urethane filled (flatproofed) tires for single and multi-piece wheels.

Equipment Needed:

  • Reciprocating Saw (any brand)
  • Metal cutting blades
  • General purpose blades
  • Safety Glass
  • Tire Iron Set (Myers part # 52349)
  • Heavy-Duty Iron (Myers part # 52353)

You will need various sizes of blades.
The metal cutting blades work best on Radial tires. General purpose fine tooth blades or knife blades are better for Bias type tires. Knife edge blades are made by grinding the teeth down on general purpose blades with a grinder. They can then be sharpened to cut the urethane. Short blades should be about 4 inches in length.

Myers Tire Supply Toll Free Number 800-998-9897 Internet www.myerstiresupply.com

Wheel recovery is a two step process. Step one is to remove the tire from the urethane. Step two is to remove the urethane from the wheel. Short blades are for cutting through the tire. If the blade is to long it will cut into the urethane For Radial tires use the metal cutting blade, for Bias use the knife edge blade.

1. Tire Removal
Begin by placing the tire on its side. Place a short blade in the reciprocating saw. Starting at the shoulder of the tire, make a diagonal cut to the sidewall then proceed to cut around the tire stopping at the point where you made your first diagonal cut (see fig.1). Turn the tire over and repeat this procedure for the other side. Now cut across the tread area of the tire and connect the diagonal cuts. The tire can now be removed from the urethane.

2. Urethane Removal
With the tire still on its side, change blades on the reciprocating saw to a longer blade. Choose a blade about 80 % the width of the wheel. The objective here is to cut the urethane into several pieces and pull it off the wheel. Make a cut at the 12 and 6 o’clock positions. Try making small cuts first until you become accustomed to how the saw performs. Change blades as necessary. Let the blade do the work. Using a tire tool, try to ply the urethane away from the wheel. Some people find it helpful to cut the urethane into 4 sections (see fig. 2), cutting at the 3 and 9 o’clock positions and remove a quarter piece at a time. Some users report that knife edge blade works best on Arnco’s Super- Flex while others prefer to use a finer tooth blade. You will need to experiment yourself to find out which works best for you. Once the urethane has been removed from the wheel it can be further cut into smaller pieces for disposal, see Fig.3. After the urethane is removed from the wheel, the remaining bead section of the tire can be removed with the tire iron set from Myers.

The cutoff method works for single and multi-piece wheels. The tire tools mentioned in this article can be used to remove the lock rings on multi-piece wheels. One method that can be used for multi-piece wheels is to use a large press to collapse the sidewall enough to remove the lock ring. Once the lock ring is removed from the rim, the wheel can be pressed out. If you don’t have a large press or the wheel guides this method won’t work for you. Pressing the wheel out is much faster than cutting the tire off but requires specialized equipment and training. You should not attempt this unless you have been properly trained to safely operate a tire press.

Tech Tip – Safety First! Basic rules to follow

17 Sep, 2010

Follow safety regulations

Whenever you are foam filling a tire with Arnco Tire flatproofing products there are several safety regulations that should always be followed.

  1. Always wear safety goggles and chemically resistant gloves.
  2. The tire being filled should always be put into an approved tire safety cage.
  3. When filling a tire don’t turn your back on it for an extended period of time and never leave the pumping area while the pump is on.

Possibly the most important thing you need to remember is to make sure the tire itself is venting properly. If air is trapped in the tire then pressure can build rapidly causing the tire to rupture violently.  There are two ways to check if a tire is venting.

  1. The easiest is to hold your hand over the needle used to vent the tire during the final stages of the pumping process.  If you can feel air coming out of the needle then the tire is venting properly.
  2. The second way is to use the pressurization gauge.  If you are not sure that the air is being released.  Stop pumping and check gauge.  If there is no pressure buildup then you are ok.

If you cannot feel air venting or if there is a buildup of pressure use a drill to bore out the vent hole and check the vent needle itself for blockage.

Filling tires is not a “no-brainer process” and pressurizing a tire with Arnco is not the same as pressurizing a tire with air.  When pressurizing a tire with air, doubling the amount of air will double the pressure.  However, it may take only one stroke of the pump to produce 100 psi of liquid pressure in small tires.  The pumping system can create pressures higher than the burst pressure of many tires and wheel assemblies.  Extreme caution should be used when inflating tires with liquid or air.

Follow these rules to have a safe day at work.
