Conveyor Belt Case Study

Conveyor belt

Includes Repair & Industrial Coatings Work

CHALLENGE

The customer was doing a full belt refurbishment with rollers, belts, drives, and counterweight, during a scheduled outage. They had received notice that some supplies had been delayed and had decided to capitalize on the delay to sandblast and paint the structure for corrosion control. So after some mechanical repairs were made, the Nix Field Coatings Team was allotted 7 days to blast and coat over 120 feet of conveyor and catwalk!

SOLUTION

Nix was able to utilize a Bull Pot Blasting setup in order to run 4 blast lines simultaneously. This allowed for high output of blast media and increased production.

We also scheduled a two shift turn around in order to fully utilize our equipment, only shutting off in order to do a pre and post shift safety discussion. 

After blasting was completed we then spray applied two coats of industrial epoxy to all the steel structures and frame. At the end of the project, we then topcoated the safety feature with a safety yellow urethane.

RESULTS

Nix completed the project ahead of schedule without any delays from weather or safety issues despite having several people working closely together and some less than favorable conditions. This provides corrosion protection for their equipment and a safe working platform for employees to access the belt for routine maintenance and inspection. We are happy to have the opportunity to serve our customers and help them continue to run safe and efficiently.

Fan Housing Case Study

Fan Housing

Includes Metal Fabrication & Shop Coatings Work

CHALLENGE

A manufacturing customer came to us with the following issues:

  1. Build up on the fan due to coolant and exhaust was causing the fan to be imbalanced, which in turn made the bearings and the electric motor fail prematurely.
  2. The fins inside the housing that were centering the electric motor mount were cracking.
  3. When the motor would fail due to the above points, it would deflect the outside of the housing and cause the housing to permanently deform.
SOLUTION

We decided to powdercoat the housing itself in a high gloss powder and coat the fan blades in anti-graffiti coating. We worked with the customer to implement a P.M. program where they power wash it monthly. The anti-graffiti paint allows the build up to easily come off when washed.

We added stiffener rings to the outside housing to keep it from deforming when/ if the motor failed.

To eliminate the fins from cracking, we added a band to the outside of the housing and connected the tie bars on the back of the motor in a 45 degree direction to absorb radial torque from the motor.

RESULTS

This allowed us to prolong the life of the housing and electric motor by eliminating imbalance on the fan and absorbing the radial torque from the electric motor on start up.

Benefits of Roof Coatings

5 Benefits of Roof Coatings

Roof coatings offer multiple benefits to businesses or facilities that are looking to repair their roofs and are evaluating their options. Whether your facility is looking for an immediate fix to a leak or is more interested in preventative maintenance, roof coatings can help extend the roof’s life, prevent leaks, increase energy efficiency, decrease costs, and are less intrusive than single ply roofing systems.

5. Extends Life

The life expectancy of a roof coatings system is 10-20 years depending on your choice of coatings. The exceptional aspect of coatings is the ability to recoat the roof system at the end of its life and therefore be long term cost effective at maintaining the roof system on your facility. 

4. Monolithic

The majority of leaks on singly ply roofs are at the overlapping seams.  This occurs when ponding water or ice builds up and flows back into an overlapping area. Coatings provide a monolithic or “seamless” roof system to the entire roof area therefore minimizing the risk of a possible leak.

3. Energy Efficiency

Due to the majority of our roof coatings being white, your business will notice a significant increase in energy efficiency due to the reflective nature of the coatings.  According to Conklin Roofing Systems, studies have shown that highly reflective roofs lower roof temperatures by up to 40% and decrease the amount of heat transferred into a building’s interior.  Spray foam systems add an additional layer of insulation under the reflective coatings cutting energy costs even more. 

2. Cost-effective

When you choose to coat your roof instead of replacing it, you eliminate the need for additional labor costs during the tear off phase.  Coating a roof decreases the turnaround time of the roof repair therefore being more cost-effective to the customer. 

1. Less intrusive

One of the most important advantages of coating your existing roof substrate is the non-intrusive nature of coating over the existing roof versus doing a full tear off and replacement.  By doing this you eliminate the need to have the facility open to damages caused inclement weather throughout the project. This will minimize downtown and cause as little inconvenience to the facility as possible.

Roof Refurbishment

Roof Refurbishment

Nix Mobile Coatings had a customer concerned with replacement of a leaking roofs at their facilities.  To save the customer costs an overcoat system was chosen to reduce tear off expenses.  The roof was pressure cleaned and deoxidized.  Some sections of the failing roof were cut out and overlaid with decking.  Approximately 1 inch of closed cell spray foam was then applied to create a monolithic (seamless) roof coating.   Following the spray foam application, we top coated the foam with a specialty polyurea coating to protect the foam application from environmental factors in the surrounding area.

This roofing system will have a life of 20+ years for the customer.  A full tear off project of the roof would have cost the customer 3 times the investment for our system while saving them weeks on installation.   We are proud of our team for their hard work on this great roof coating system and grateful to help our customers find cost saving solutions to keep them running safe and efficient.
