NACE CIP 1 EXAM Questions With 100% Correct Answers - Latest Update 2023 | 2024 (Graded)

what is a main requirement for a hydrolysis coating to cure - answermoisture or humidity Industrial and marine coatings are commonly referred to by: - answergeneric resin/binder type Oil based coatings applied over alkaline surfaces may result in: - answersaponification list 5 of the formal sections usually contained in a good specification - answerscope of work, terms and conditions reference standards and codes safety pre-job conference surface prep coating materials and schedule workmanship sampling application work schedule inspection documentation basically everything what are 2 of the inspectors responsibililties as it relates to the specification - answerto enforce it NOT to make any changes acid cleaners - answercleaners that remove soil by chemical attack alkaline cleaners - answerCleaners that saponify most oils and greases, and their surface-active components wash away other contaminants. These cleaners may also saponify certain coating vehicles. ceramic grit - answerRelatively expensive abrasives that are justified by their special properties. Their particles retain sharp cutting edges, and are especially effective on hard-base materials which may resist effective blasting by chilled cast iron grit. crushed slag - answerRelatively cheap abrasives that are formed by metallurgical processes or combustion (Black Beauty) detergents - answerCleaners that are composed of buffering salts, dispersants, soaps and inhibitors Dry Grit Blasting (Air Blasting) - answerBlasting that uses a highly concentrated stream of grit projected at a surface to remove rust, mill scale, or other contaminants, creating a rough surface that is good for adhesion. emulsion cleaners - answerCleaners that are sprayed onto the surface where they function by wetting, emulsifying, dispersing, and solubilizing the contaminates faying surface - answersurfaces joined to create a friction grip gouges - answerSharp indentations in the substrate inconclusions - answera non-metallic phase, such as an oxide, sulfide, or silicate particle in a metal organic solvents - answerSolvents that clean the metal by dissolving and diluting the oil and grease contamination on the surface. such as kerosene, turpentine, naphtha, mineral spirits, toluol, xylol, etc., pre-cleaning - answerCheck of the surfaces for contamination before surface preparation begins. surface lamination - answerThe most common surface defect on steel substrates. It is typically caused by rolling the steel. Surface Profile (Anchor Pattern) - answerThe irregular peak and valley profile on a bare surface that can result from operations such as abrasive blast cleaning or power tool cleaning Venturi Nozzle - answerThis blasting nozzle permits abrasive velocity up to 720 kph (450 mph), or 660 ft/s with an almost equal impact over the entire surface. Venturi nozzles are the most effective shape for tough cleaning jobs. water blasting - answerUse of water with abrasive included in the stream or using wet abrasive waterjetting - answerUse of standard jetting water discharged from a nozzle at pressures of 70 MPa (10,000 psig) or greater to prepare a surface for coating. weld spatter - answerParticles of molten metal produced during welding and thrown onto the surface adjacent to the weld during surface prep, surface cleanliness should be inspected a minimum of the 3 following times - answerbefore any surface preparation activities after surface prep, before coating between each application of coating in a multicoating system Factors during surface preparation that may effect service life include: - answerresidues of oil, grease, soil residues of nonvisivle chemical salts rust on surface loose or broken mill scale rust scale anchor pattern defects mehcanical cleaning equip
