What is a Critical Control Point?
A Critical Control Point (CCP) is any point in the manufacturing process where the surface condition of a material has the opportunity to change—intentionally or unintentionally—and impact adhesion, in a positive or negative way.
Why should you care about them?
The wait is finally over. Making its world debut at MD&M in Minneapolis, the Surface Analyst XA integrates the power, simplicity and ease of our handheld Surface Analyst directly into the manufacturing process. Now, the most precise surface monitoring technology will seamlessly unify with any production line, magnifying the speed and efficiency of surface quality control.
Autumnal vibes have landed at BTG Labs and along with football-watching, apple-picking, Halloween costume-planning we have an array of opportunities for you to interact with us and learn more about the Surface Analyst.
As the wind energy industry grows—by 2020 it is expected to provide 10% of the nation’s electricity— wind turbine manufacturers must strive for the most reliable and efficient product that operates reliably and seamlessly. Adhesion failures in the field, are unacceptable and even dangerous, but still occur.
Wind turbine manufacturers are making it a priority to overcome adhesion failures in the field and implement ways to ensure repairs only need to be done once. Currently, wind turbine repair is extremely expensive: in most cases, the part must be shipped back to the manufacturing plant for repair. And most importantly, turbine failure could be damaging and dangerous to what could be in the vicinity.
Adhesion failures most often happen due to improper surface treatment prior to adhesion. Optimizing adhesion processes and gaining control of the bond surface guarantees a reliable bond and prevents failures in the field.
As a result, wind turbine manufacturers are turning to the best in surface cleanliness gauges: The Surface Analyst.
BTG Lab’s recently held another successful webinar. Hosted by Products Finishing and presented by Dr. Giles Dillingham, the webinar emphasized the importance of monitoring cleaning processes and explored different ways to measure surface cleanliness.
In the webinar, Dr. Dillingham discusses measuring surface cleanliness as a way to quantify cleaning processes. By measuring the success of cleaning processes, manufacturers can determine the ideal solution for their application.
Precisely evaluating cleaning processes with water contact angle is a fast, easy, accurate, quantitative to way to gain ensure consistency and precision on the factory floor.
Challenges often arise when verifying critical surface processes on the factory floor when measuring hard to reach areas and varying angles. The Surface Analyst conquers those challenges with the unique ability to measure on vertical surfaces, which include assembled parts and hard to reach spots. This allows for easier surface analysis on the factory floor.
A few examples of the Surface Analyst’s ability to measure on vertical surfaces on the factory floor:
- Airplane wings prior to bonding, painting, and repair
- Canopy of jet fighters after cleaning
- Wind turbine blades prior to bonded repair
- Silkscreen bottles post flame treatment
- Ship hulls prior to painting and bonding
- Interior of automobile headlights prior to application of anti-fog coating
- Windshield bond lines prior to sealing
- Class A paint surface for decals applications and reapplications
- Measuring appliances after metal cleaning and prior to power coating
Last month, Elon Musk announced the availability of Tesla’s new solar roof. These solar roofs are made to masquerade as tasteful, modern shingles; their attractive panels offer roofs from sleek modern to French slate. The solar panels are hidden in a pane of glass which contains a hydrographic coloring–a process that uses water to apply printed designs– to provide texture.
But, these shingles must not only look good, like all solar panels, they must be tough enough to withstand elemental threats.
Wind, rain, snow, sun, extreme temperatures–these are all stresses to any structure, especially solar panels. Because solar panels serve as an energy source, there is no room for failure in the field. The bonds that keep them together such as bonds between dissimilar materials, bonds on low energy polymers, coatings, laminates, and seals, must withstand the stresses as well. That’s why solar panel manufacturers turn to the Surface Analyst.
Plastics manufacturers are all too familiar with the challenges of bonding thermoplastics. Last week, BTG Labs successfully hosted a webinar with Plastics Technology to discuss improving bonding of thermoplastics. The webinar, entitled “Understanding Surface Energy: How to Measure and Control the Surface Properties of Thermoplastics to Maximize Adhesion,” brought in almost 400 registrants.
Presented byBTG Labs’ Chief Scientist Dr. Giles Dillingham who discussed the surface characteristics of thermoplastics. Dr. Dillingham also explored surface treatment processes such as flame, corona, and plasma, and ways to monitor and verify those processes. The ability to understand and measure the surface precisely is the key to successfully bonding thermoplastics.
Roosevelt University, a liberal arts college in the Loop of downtown Chicago perfectly contrasts antiquated and contemporary architecture. Roosevelt’s first venue, constructed in 1889 just in time for the World Fair, is 17 floors of beautiful Art Nouveau structure. The Auditorium Building encompasses ornate railings and scaffolding, topping off with a regal library and a lofty tower overlooking Grant Park. However, because of its age, the Auditorium Building demands constant attention and is inefficient in the frigid Chicago winters and hazy summers.
Their new building, the Wabash Building, erected in 2012 is just the opposite. Its 32 towering floors of curved glass superintends the Auditorium Building, arriving amongst the structural giants of Chicago. Illustrating the epitome of modern design, this highly efficient, state of the art structure is LEED certified.
When looking up at the two buildings, old charm vs new-age sleek, the phrase comes to mind: they just don’t make things like they used to. But, there’s necessity behind this. As the global population rises, infrastructure becomes denser, and resources become scarce, engineers concentrate on building smarter. Designing a building that spares no expense—in terms of efficiency in operation and manufacturing of these smarter materials—is pivotal. This all begins in the research and development lab and extends to the manufacturing floor. Materials and processes are developed to allow for more efficiency in both the production of materials and the final construction. Guaranteeing bonds will hold; paint, print, and coatings will stick; seals will persevere; and cleaning processes will clean effectively is crucial to manufacturing a product that will withstand stresses of any structure.
That is why more and more manufacturers are turning to the Surface Analyst™. This hand-held instrument ensures any surface is ready for effective bonding, coating, cleaning, sealing, printing, or painting. The ability to verify and quantify critical surface processes on the manufacturing floor is the keystone to efficient manufacturing and smarter structures.
A high-grade window manufacturer, for example, uses the Surface Analyst to verify plasma treatment on vinyl window frames prior to sealing. This guarantees the windows will efficiently heat or cool a structure while also withstanding the elements of rain, wind, and snow. …Read More
