Q

Summarize how corrosion forms and the electrochemical process that occurs at the anodic and cathodic sites

A

ACME - A = anode C = Cathode M = Metallic Pathway E=Electrolyte
Anode = most reactive (less stable) = where oxidation occurs = loss of electrons
Cathode = less reactive (more stable) = where reduction occurs = gain of electrons
Metallic pathway = ususally the substrate (passage of electrons)
Electrolyte = conductive medium where ions are carried from anode to cathode

Q

Explain 3 mechanism by which coating protect against corrosions

A
  1. Barrier Coatings = physical and chemical barrier between the substrate and environment. Impedes the ingress of o2 and water and soluble salts. Cannot eliminate moisture permeation. (Epoxy)
  2. Sacrificial Coating - use more active coatings like zinc that is anodic to steel. provides cathodic protection.
  3. Inhibitive - act as a barricade, actively slowing down the reactive at the anode, cathode or both. Applied as a primer and NOT used on immersion conditions because it uses pigments that draw waters into coating to activate the chemcial reaction.

Q

Describe the 4 components of a coating and their functionality

A

1.Pigments = solid particles , color, level of shine, beneficial properties (UV, water resistance) , NOT present in all coatings , do NOT dissolve, can provide cathodic protection
2. Binders or Resins - hold the coating components together, provide strength, hardness, flexibility. ONLY compoent of a coating that MUST be present. (alkyds or epoxies = aka) , backbone. STABLE/PROTECTIVE FILM
3. Solvent - affect wetting of substrate, viscotiy, drying speed, serve NO purpose after coating is applied and cured. May contain VOC or HAP (hazardous air pollutants). 2 major characteristics = solvency power (ability to dissolve the resin) and volatility (governs Evap rate)
4. Additives = use to enhance performance, ~less than 5% of the total coating

Q

Factors that affect rate of corrosions (3)

A
  1. Type of metal - more active vs less active metals (Mg,Zn, AL = most active, gold plat = less active)
  2. Type of corrosions - general vs local
  3. Service environment - rural = less CR , marine = high CR

Q

QC vs QA

A

QC = contractor’s responsibility, focus on the DETECTION of defects, MANAGES the quality of work performed
QA = owner’s responsibility , focus on the PREVENTION of defects, VERIFIES the quality of the work performed

Q

Outline the process for performing inspections task to a high standards (5)

A
  1. Plan - review specification, industry standards and PDS and SDS. Clarify responsibilities, authorities, and delieverables, go to pre-job conference, know how to use any required equipments. Create ITP
  2. Assess - visual inspect to determine conformance - monitors and examine the work performed , example mixing, recoat intervals. weather conditions, materials storage, Inspectors are NOT supervisors.
  3. Test - In addition to visual, test and measurements are required. they should know how to operate all equipment and perform each test, keep all equipment in working order, conduct inspection test openly, honestly, and accurately.
  4. Verify - After observation/testing , need to verify conformances and compare the results aginst specfication/ITP/PDS and standards or any deviations. Non conforming work must be reported
  5. Document - inspector document observation, measurements, and test data. Accurate and thorough manner, submit in a timely manner. logbook, daily reports, weekly reports, NCR, CAR, Materials inventory, Calibration reports, Final inspection report
18
Q

Reconigze the characteristic that quality coating inspector posses (6)

Q

Prior to the start of a project, the inpsector must have clear understanding of (3)

not the inspector responsibility, but it is their responsibility to report any issues that may affect the project.

27
Q

primary objective of inspector and what should it not do

A

verify it meets specification , should not edit or change

28
Q

Describe the role and importance of a coating project specifications

A
  1. forms the contract for project between the owner and contractor
  2. overrides all other documents
  3. acts a road map for the inspector’s rule book for the project
  4. defines the inspector’s responsibilities, authority and deliverables.
29
Q

specifications must be

A

must be well written since the inspectors verify the coating are installed per the specifications, a poorly written can lead to lawsuits, costly rework and premature coating failure.

30
Q

Describe the role of standards within a coating projects

A

standards are formal documents produce by key industry bodies that provide guidance for carrying out technical procedures
1. Establish indsutry agreed upon (uniform) criteria for - test, methods, processes or practices
2. when reference within the specfication are considered binding and can be specficied in part or while

31
Q

role of inspector: standards (5)

A
  1. know which stages of the project are governed by industry standards
  2. read and understand every part of the standards
  3. determine if any fed or lcoal codes or standars are applicable
  4. look for discrepancies between the referenced standards and specficiation
  5. always check for secondary standards that are referenced indirectly in the specifications “
32
Q

Located key info with PDS , SDS and product labels “these are the 3 sources of product information,

A
  1. PDS - details and instructions necessary to properly and succesfully install/use a product. (surface prep/ storage/ mix and thinning / application procedure/ DFT requirements)
  2. SDS - standardized documents produced by manufacturers. GHS (Global harmonized system) states an SDS must be supplie with all paint ,solvents, cleaners. Outline the requirement for handling storing and transporting a product. Consist of 16 sections (general info, safe handling, and emergency control / technical and scientific data / ecological impacts, disposals, transportation / hazards of eachchemical exposure and PPE)
  3. product labels ( need to review)”
33
Q

HAZCOM states that people

A

have the right to know the hazards of the chemical they are exposed to

34
Q

role of inspector: safety and PDS (5)

A

“1 read PDS and SDS
2. verify the date of publication that the correct version is being used, and country and version
3. idenfiy the GHS pictorgrams and wear the proper PPE
4. look for discrepancies between the data sheets and specfications”

35
Q

2 responsibilities of inspector as it related to the specification?

A
  1. enforce it
  2. NOT make changes to the specification
36
Q

well written specification does what?

A

provide clear understanding of what is expected throughout the coating project

37
Q

written specification overrides the PDS unless

A

written permission is given to go outside the specfication and is approved

38
Q

Role of inspector: specification (3)

A

“1. Read and identify any inconsistencies, ambiguities, and omissions
2. check that there is adequate information to perform the inspection
3. obtain clear understanding of the process for change or modifications “

39
Q

Components of a typical specification (10)

A

“1. scope of work or general - project to be completed and when and where the work will be completed
2. terms, definitions and acronyms
3. standards and regulations
4. pre job conference
5. surface prepartion - outline the approval methods
6. material or products - describe any material or products to be used on the project
7. coating application - outlines the approved methods of installing the coating system
8. repairs and remidial work - describe procedure for repair work
9. inspection and reporting - expectation of the owner regarding inspection testing and reporting requirements
10. safety - describes the safety requirement of the job”

40
Q

Recognize the importance of analyzing and applying Guidance Documents (pds sds)

A
  1. Specification alone rarely contain all the requirement for an inspector to perform the job thus ITP are created by pulling key information out of the specification other guidance documents
41
Q

purpose of ITP is to

A

put together in a single document all the inspection and testing requirements of the speicfications and other supporting guidance documents
1. outlines how the inspector is going to perform their responsibilities
2. serves as a reference when verifying if the work performed emet the specification
3. at a min cover all phases of work, list what to inpsect, how to inspect, and acceptance criteria
