Failure Behavior and Damage Mechanism of Acrylic Polyurethane Coating in Tropical Marine Atmospheric Environment

A new rate-dependent stochastic damage model for the dynamic modeling of concrete is presented in the paper. This model is formulated on the basis of the stochastic damage model, from which, the static stochastic evolution of damage is strictly derived. Then, rate dependency of concrete is included by means of viscous-damage mechanism. The model predictions are tested against experimental results on concrete specimens that cover different strain rates. The results demonstrate the proposed model may predict dynamic failure behavior of concrete quite well.

Air Cooled Heat Exchanger

Risk-based inspection program (RBI) is a decision making techniques for providing refineries and petrochemical plants with an effective and appropriate inspection planning. The aim of the present study is to analyze failure behavior and risk ranking of α-MDEA fin/fan cooler of CO2 removal unit based on API 581 in order to find out the reason(s) of tubes failure. According to previous experience in similar plant, risk calculation results and conducted inspection activity by using RFT eddy current technique, CO2 corrosion damage mechanism was identified as a main reason of tubes failure. In next step, process key variable, prevention/mitigation methods and inspection planning programs were determined so as to minimize the similar failure behavior in the rest of the lean amine air-cooled heat exchangers of CO2 removal unit.

Weathering Resistance

This study aims to evaluate the synergical effects of SiO2 nanoparticles (nano-SiO2) and organic photostabilizers (Tinuvin 384 (T384) and Tinuvin 292 (T292)) on the weathering resistance of acrylic polyurethane coating. Data obtained from infrared (IR), field emission scanning electron microscopy (FESEM), and weight loss of coatings (before and after aging test), suggest that the SiO2 nanoparticles play a dual role, as both reinforcer and UV absorber, thus improving effectively both the mechanical properties and the weathering resistance of polyurethane acrylic coatings. The nanocomposite coating containing 2 wt % nano-SiO2, 2 wt % T384, and 1 wt % T292 exhibits excellent weathering and abrasion resistances, offering a durable outdoor application.
