Gürgenler Bend Polyurethane Coating at Teknosan Heat and Energy in Ankara 1.02.2020 - 1.09.2021
I managed the process of applying polyurethane coating to a surface area exceeding 5000 square meters, ensuring compliance with the specified requirements for surface preparation and inspection. Throughout the project, I conducted thorough inspections and tests in accordance with the methods outlined in Table A – Requirements for Inspection of Surface Preparation. This included:
-
Visual inspections to ensure the surface was free of contaminants before blasting.
-
Environmental condition monitoring, ensuring relative humidity was below 90% and ambient temperature was above 5°C, with checks every two hours.
-
Temperature verification using thermocouples to confirm the item temperature was at least 3°C above the dew point before blasting.
-
Abrasive material checks, including size, shape, and properties, verified against BS EN ISO 11124 standards, and daily conductivity tests for water-soluble contamination as per ASTM 4940.
-
Surface roughness measurements using EN ISO 8503-4 to ensure a range of 50 to 100 microns.
-
Visual inspections post-blasting to achieve a Grade Sa 2½ cleanliness level as per EN 8501-1.
-
Dust presence checks post-dust removal, ensuring compliance with BS EN ISO 8502-3 (max. class 2).
-
Conductive measurements for salt content post-blasting, adhering to BS EN ISO 8502-9 standards (max. 20 mg/m²).
-
Final item condition monitoring before coating application, ensuring no rust and that the item temperature remained at least 3°C above the dew point.
I ensured that all inspections and tests were conducted at the specified frequencies, both during the initial qualification phase and throughout production, to maintain the highest quality standards. This meticulous approach guaranteed the successful application of polyurethane coating, meeting all project requirements and industry standards.
