NACE CIP Level 1 Study Guide - Questions and Answers, Complete Solutions What are the three different ways a coating can adhere to the surface? Chemical, Mechanical, Polar, or combo of all three The ... two broad classifications for curing mechanisms are: Convertible and Non-Convertible List two Non-convertible coating types: Chlorinated rubber, vinyl List three convertible coating curing mechanisms oxidation, co-reaction (polmerization), hydration, fusion List two characteristics of oxidation cure coatings Not suitable for immersion service, not suitable for use over alkaline substrates, limited dry film thickness per coat List three coating types that cure by polymerization epoxies, polyurethanes, polyureas, polyaspartics, polysiloxanies Induction time is: the time required by the product data sheet (coatings manufacturer) between mixing the coating and the start of application What is the main requirement for a hydrolysis coating cure? Moisture Industrial and marine coatings are commonly referred to by generic resin type Oil based coatings applied over alkaline surfaces may result in Saponification List five of the formal sections usually contained in a good specification scope of work, terms and definitions, pre-job conference, application, sampling coatings, inspection What are two of the inspector's responsibilities as it relates to the specification? Enforce the specification, NOT to make changes to the specification During the surface preparation, surface cleanliness should be inspected (as a minimum) the following three times: Before any surface preparation activities, after surface preparation - before coating begins, between each application of coating in a multi-coat system Factors during surface preparation that may effect service life include: residues of oil, grease, and soil. rust on the surface. loose or broken mill scale. rust scale. anchor pattern. surface condensation. Common design defects include: Hard to reach or inaccessible areas. rivets, bolts, or other connectors. welds. gaps. overlapping surfaces. threaded areas. dissimilar metals. construction aids Common fabrication defects include: weld spatter, skip welds, sharp corners & Edges Four typical SSPC SP1 pre-cleaning methods include: Solvent wipe with cloth or rag, immersion of the substrate in solvent, solvent spray, vapor degreasing, emulsion cleaining, chemical paint stripping, use of alkaline cleaners One standare for use with Power Tool Cleaning is: ISO St2. ISO St3. SSPC SP-3. SSPC SP-11 Four examples of tools used for Power Tool Cleaning are: rotary wire brushes, impact tools, needle scaler, disc sanders, piston scalers Two Abrasive Blasting methods include: Centrifugal blasting, sand-injected water blast, slurry blast, wet abrasive blast, dry grit blasting Visual Standards for abrasive blasting include SSPC-Vis 1, ISO 8501-1 SSPC SP 10/NACE 2 limits staining to ___ per each unit area 5% SSPC SP 5/NACE 1 limits staining to ___ per each unit area 0% SSPC SP 6/NACE 3 limits staining to ___ per each unit area 33% The two types of abrasive blasting nozzles include: Straight, Venturi The specified level of surface cleanliness must [Show More]
