The use of sustainable materials in the flooring market has gained widespread interest in recent years. Bio based raw materials contribute significantly to these efforts and are used to prepare environmentally friendly coatings. Castor oil-based emulsions are used as polyols in waterborne polyurethane coatings. These systems have outstanding chemical resistance and good durability. But they have inherent issues like very short pot life, poor appearance / flow properties, and delayed early hardness development.
Brief Background Throughout the last decades, coatings science has incorporated very versatile inorganic materials into organic coating to form the inorganic/organic hybrid coating systems. Combining various organic and inorganic constituents in combination with different preparation and processing methods, very versatile materials can be produced for optical, structural and coatings applications. The hybrid products have combined the properties of the inorganic materials, i.e., hardness, durability, and thermal stability, and organic polymers, i.e., flexibility and toughness.
This paper provides an overview of the electrochemical passivation process, history of the BurlingtonSkyway, description of the installation process, treatment results and up to 30 years of monitoringresults for the structure.
The prevention of internal corrosion remains a significant challenge during the production of oil and gas. The use of film forming corrosion inhibitors is an important and cost-effective means of protecting assets from corrosion. These chemicals operate by forming a protective layer between the corrosive species present in the produced fluids and the pipe surface.
Corrosion under Insulation (CUI) is accelerated corrosion that takes place under insulation typically used to conserve energy, help with process control, and protect workers from temperature extremes. CUI is an issue for facility owners in many industries that use heat or cold in their industrial processes, including chemical processing, refining, fertilizer manufacturing, and power generation. Insulation used in these applications is generally mechanically attached to the substrate vessel or pipeline and is typically covered with cladding. Cladding is typically made out of metal or plastic and is applied to protect the insulation from physical damage and to keep water away from the insulation and substrate.
Inorganic fouling in oilfields has resulted in millions of dollars of operating expenditure every year since the inception of offshore oil and gas drilling, where mineral scale deposition in tubing, flowlines and downhole equipment leads to significant production downtime. Calcium carbonate (CaCO3) fouling is endemic in oilfield systems, as produced water containing both bicarbonate and calcium ions is prone to form precipitates as a result of pressure changes during production.The release of carbon dioxide gas from the aqueous phase prompts the evolution of carbonate resulting in a rise in pH and consequent precipitation.
The Energy Innovation Center’s approximately 80-year-old concrete floor had significant divots and was badly spalled and cracked. The concrete floor, often referred to as “The Racetrack” due to its oval shape, serves as the main hallway to a newly renovated technology hub and needed significant structural and aesthetic work. The re-finished floor had to offer durable functionality as well as blend into the neo-industrial look of the re-tasked building.
Polyaspartic coatings have been used for years in high-performance industrial protective applications such as bridge infrastructure, water and wastewater, and transportation. More recently, these types of coatings have begun to migrate into commercial and architectural applications due to end users’ desires to protect their architectural infrastructure while maintaining a high degree of aesthetics and beauty.
Aboveground storage tanks (ASTs) are assets that contain valuable goods for the oil and gas industry. Consequently, monitoring and preventing loss of containment and extending the service life of those assets is a priority for the abovementioned industries. To monitor the degradation process of the tanks, ER probes are typically used to determine the corrosion rates. Corrosion rates can be used to forecast the service life of an asset by estimating the time at which the degradation reaches a critical thickness of the tank. If the corrosion rate is such that the critical thickness is expected to reach below the expected service life of the asset, the lifespan can be extended by corrosion mitigation methods.
This paper presents the diagnostic work undertaken to determine the cause of failing coating and spalling block on the exterior of a commercial building in northern Illinois. The field assessment methods used to diagnose the problems including non-destructive and destructive methods for determining moisture content in the masonry, infrared thermography, and visual assessments are described.
The Springhouse Country Market and Restaurant has been a local icon for over 40 years. The commercial bakery floor had been covered for years with a commercial sheet vinyl that would fail in spots due to the infiltration of water and cleaning materials at the seams. This resulted in the need to repair the sheet material several times which created a patchwork effect. Finally, the owner reached out to a flooring professional to discuss a new renovation solution.
