Polyyrea Flooring Systems for Concrete a Practical Approach

Product Number: 41205-176-SG
Author: Robert G. Johnson
Publication Date: 2005

Spray applied polyurea was introduced to the construction industry in the late 1980 s. By the 1990 s, polyurea floor systems were being installed using early formulations of polyurea, and spray equipment adapted from the polyurethane foam industry.  Advancement in raw materials, polyurea formulations, specialized equipment and contractor expertise in recent years has provided increased opportunities for this technology to be used in a wide variety of concrete flooring applications.

New high-solids compounds for two-component (2K) topcoats based on polyurethane, polyurea and polysiloxane binders are examined with respect to their competitive potential in Europe. Against the backdrop of EU-wide VOC legislation, the relevant market for OEM topcoats applied in stationary facilities is currently estimated at 20,000 t with a material value of a good EUR  100 million.

Potential Distribution and Polarization Effect of Storage Tank Bottoms With Cathodic Protection Applied by MMO-Coated Titanium Anode Grids

Mixed metal oxide (MMO) is widely used as anode material for the cathodic protection of storage tank bottoms due to its advantages such as low consumption rate long service life and ideal current distribution. However with the elapse of service time the MMO CP systems have been found with such issues as low polarization level and uneven potential distribution threatening the operation safety of storage tanks. In this study numerical modeling and subscale experiment were chosen to clarify the main factors responsible for the aforementioned issues. The results indicated that the inadequacy of polarization and the lack of uniform potential distribution were related to a combination of multiple factors including the anode-to-tank bottom distance the impressed current level and the number of drain points. On the basis of these systematic analyses this paper conclusively proposes certain design principles and maintenance suggestions for the cathodic protection system of tank bottoms.

There are very few markets that have not been affected by powder coatings. Powders are used widely throughout the automotive industry for underhood parts, wheels, trim, and as full body primers.  Whereas it is unlikely that powder coatings will ever replace liquid color coats in automotive assembly plants, some companies have has made full body powder clear coats a reality.

Practical Galvanic Series for Improved Materials Selection in Sweet Systems

In oil and gas production and transportation dissimilar materials are frequently combined for technical and economic reasons. However the combination of dissimilar metals can result in corrosion due to galvanic or bimetallic effects. The driving force for this kind of corrosion is the difference of the corrosion potentials of the individual materials in the given environment which causes element currents the magnitude of which depends on the sum of all system resistances (Ohmic Law). Any assessment of the corrosion rates at bimetallic couplings needs the information on the corrosion (rest) potentials of the bimetallic partners in the relevant medium.Due to the lack of consistent literature data a practical galvanic series was established in this work for standard oil country tubular goods (OCTG) steels corrosion resistant alloys (CRA) as well as graphite (as gasket material) in a model sweet upstream environment. From polarization resistance measurements information was obtained on the corrosion rate of the C-steels in the absence of bimetallic coupling. Furthermore the corrosion rates encountered at the partners of bimetallic couples were quantified via mass loss measurements. The results of this work allow better assessment of the severity of bimetallic corrosion and hence a more appropriate selection of materials which prevents corrosion failures increases the integrity of assets and saves costs.

Predicting Accumulated Galvanic Corrosion Damage Using A Service Life Model

Aircraft and similar structures are exposed to many different types of environmental conditions over their operational life and this very much determines the type of damage they experience. For example sea based aircraft experience a much more aggressive environment than land based aircraft. Therefore it is critical to know the environmental exposure of an aircraft over the course of its lifetime to make meaningful predictions of accumulated corrosion damage.Computer simulation models have been demonstrated to be able to predict the rate of corrosion and the incidence of pitting but they require information on the electrolyte thickness conductivity/corrosivity and the polarization properties of the material. Therefore to use a computational model to predict the corrosion rate for an aircraft at a particular point of time during its service we would have to define the model parameters at that time as well as the exposure history.In this paper a service life model concept is developed based on environmental data collected using sensors combined with a galvanic corrosion simulation model. The galvanic simulation model input data is identified from the sensor data to predict the accumulation of corrosion damage. Applications of the model are presented and discussed.The approach is applicable not only to aircraft but to a wide range of structures.
