It is typically of the most concern as damage is concentrated and loss of integrity or structural failure can result. List some of the common tools/methods used for corrosion control - Answer - - design - inhibitors - material selection - cathodic protection - protective coating - splash zone systems - alteration of the environment How does NACE define the inspector's role? - Answer - The inspector's role is that of a quality control technician responsible for observing and reporting conformance or deviation from the project specification. What is the inspector's responsibility when it comes to safety on a project? - Answer - Safety enforcement is not the responsibility of the inspector, however, it is his responsibility to report any issues that may affect the project Name some tests that may need to be conducted during surface preparation and coating operations. - Answer - Temperature, RH, DP, Anchor Profile, Surface Cleanliness Name some of the documentation/reports that may be required to be maintained on a coatings project. - Answer - Daily, weekly summary, materials usage report, manpower and equipment, non-conformance, conformance What are the most important characteristics of a good report? - Answer - Objective, Accurate, Detailed What is the inspector's primary responsibility and what should the inspector not do as it pertains to the specification? - Answer - - enforce specification - do not make changes What type of information should you expect to find on a Product Data Sheet? - Answer - - Surface prep and application info (i.e. recommended surface cleanliness) - Recommended application methods and equipment (tip sizes) - Environmental parameters for application What type of information should you expect to find on a Safety Data Sheet? - Answer - - Health, Safety and Environmental - PPE required - Physical characteristics - Emergency responder info Difference between QA and QC - Answer - QA: any systematic process of checking to see whether a product or service being developed is meeting specific requirements QC: a procedure or set of procedures intended to ensure that a manufactured product or service adheres to a defined set of quality criteria or meets the requirements of the client or customer Identify some of the defects that can be caused by incorrect application temperatures - Answer - - failure to cure - too rapid solvent evaporation - poor film formation Describe relative humidity - Answer - The amount of moisture in the air compared to saturation level What is the dew point temperature? - Answer - Temperature at which moisture will begin to form on a steel surface Name some of the effects wind may have on a coatings project - Answer - - blowing abrasives - causing excessive drift or overspray - accelerating solvent evaporation - contributing to the formation of dry spray What are some of the common errors when using an electronic hygrometer? - Answer - Failure to acclimate the instrument to the environment with adequate time Explain the process for use of the sling psychrometer - Answer - - make sure the wick is wet and clean - continue to "sling" until 3 consecutive readings are achieved Desirable properties of a coating: - Answer - - chemical resistance - water resistance - ease of application - adhesion of substrate - cohesive strength - flexibility and elongation - impact resistance - abrasion resistance - temperature resistance - dielectric resistance Two broad classifications of coating are: - Answer - Organic/Inorganic, Convertible/nonconvertible, thermosetting/thermoplastic What are the 2 primary components of a liquid applied coating? - Answer - - pigment - vehicle (resin or binding) What are the 3 methods by which a coating provides corrosion control? - Answer - - barrier - inhibitive - sacrificial What are the 3 different ways a coating can adhere to the surface? - Answer - - chemical - mechanical - polar - all three The two broad classifications for curing mechanisms are: - Answer - - convertible - non-convertible
