Aesthetic Issues With Spray-Applied Fluoropolymer Coating System

Product Number: 51322-17971-SG

Author: Kimberly Steiner

Publication Date: 2022

$20.00

A building, partially clad in fluoropolymer coated aluminum panels, was observed to have an aesthetically unacceptable appearance while still under construction. Once installed on the building, many of the panels exhibited a vertical streaked appearance under certain conditions. When the panels were at ground level, or when the sun was bright, the streaky appearance was not noticeable. However, in conditions of low light, such as during early morning, dusk, or on cloudy days the streaky appearance was reported to become apparent. A visual mock-up, consisting of multiple coated panels that had been approved by the architect as a guide to the anticipated appearance were also present on-site as a reference. This visual mock-up was used as a reference for acceptable appearance of the coated panels.

Environmental assisted fatigue, also known as corrosion fatigue, is a well-known degradation phenomenon in structural materials that may develop as a consequence of long-time exposure of components to cyclic loads at the presence of an aggressive environment. This phenomenon constitutes an increased environmental risk for fatigue initiation in many industrial applications. One such application is the piping system in a nuclear power plant where the structural material is subjected to an aggressive water environment. Here, the cyclic loads arise from thermal fluctuations and mechanically induced vibrations.

An Innovative Thermoplastic Coating For CUI Applications

Product Number: 51322-18122-SG

Author: Hindrik Harm Broesder, Somaieh Salehpour, Dinko Cudic

Publication Date: 2022

$20.00

An innovative thermoplastic type of coating material based on pure isobutene homopolymer was investigated to determine whether it would be fit for purpose in CUI services at low and moderate temperatures up to 120 °C. This polymer is commonly called Polyisobutene (PIB) and has a unique set of properties that are beneficial for protecting metallic structures from corrosion. Polyisobutene is a polyolefin with a chemical structure similar to Polyethylene (PE) and Polypropylene (PP). One of the major differences is that PE and PP are solid materials with a high degree of crystallinity, whereas PIB does not have a crystallization or melting temperature. PIB has a glass transition temperature (T_g) below – 60 °C which indicates that the polymer is a liquid above this temperature.

Coatings for metal protection is a very broad area of research and no single formulation technique is used. Generally, coatings contain micropores, areas of low cross-link density or high pigment volume concentration that provides a diffusion path for corrosive species such as water, oxygen and chloride ions to the coating/metal interface. Therefore, incorporating corrosion inhibitors into a coating system is a basic step required for corrosion protection [1]. Direct addition of corrosion inhibitors has almost always resulted in undesirable leaching of inhibiting molecules and subsequent reactions with the coating matrix. This reduces the effect and duration required to protect the substrate in the aggressive environment. The encapsulation of corrosion inhibitors into a host material as using nanocontainers is an effective delivery system of the corrosion inhibitor in active corrosion protection application [2].

Accident scenarios, such as a loss-of-coolant accident (LOCA), subject claddings to rapid thermal transients, internal loading, and a high temperature steam environment. Understanding cladding behavior in this dynamic setting allows for better assessment of safety concerns such as coolant flow blockage and fuel relocation and dispersal. Improvement in model predictability and multi-physics fuel performance codes such as BISON are at the forefront of cladding related research. Particularly, efforts aim at addressing model accuracy to support burnup extension and increases in fuel cycle lengths.

Impressed current rectifiers are the backbone of a pipeline operator’s cathodic protection (CP) systems. A rectifier’s ability to protect a large length of electrically continuous pipeline considerably improves efficiencies and reduces material costs as compared to galvanic systems. However, like galvanic anodes, impressed current anodes are a consumable asset, and require replacement at the end of their service life to ensure that the rectifier can continue to adequately protect the pipeline.
