Blade Repair Standard / V4 2023-05-02
a. the function of the paint layers on a wind turbine blade and describe the materials from which paint products can be made b. the health and safety risks associated with paint products by considering the base and hardener materials and the solvents used to thin the paint c. the precautions to be adopted to mitigate the health and safety risks posed from paint products by considering the use of PPE and the type of filters required for a mask
d. the term ‘flash-off time’ in the context of paint products
e. why it is important to follow a blade manufacturer’s work instruction for painting a blade by considering the correct surface finish for paint adhesion, whether the paint requires one or two coats, the curing time for the paint, and the ambient humidity and temperature limits
Demonstrate how to calculate the amount of paint required for a given surface area and layer thickness
Demonstrate how to mask off an area of blade repair for painting
Demonstrate how to apply paint to a repair using a foam roller, and how to measure the layer thickness using a wet film gauge Continually assess and give feedback on the participants’ ability to apply the knowledge gained during the general safety module to the working environment to mitigate the risks associated with composite repair work Facilitate practice to improve the participants’ ability to select the correct mask and filter for working with paint products Facilitate practice to improve the participants’ ability to safely apply paint to a blade surface to a specified layer thickness and to be able to measure the layer thickness with a wet film gauge. The trailing edge section built in Lesson 19 can be used for this Give constructive feedback on the participants’ ability to select the correct mask and filter for working with paint products, to safely apply paint to a blade surface to a specified layer thickness, and to measure the layer thickness with a wet film gauge.
The participants shall:
Practise the ability to:
a. select the correct mask and filter for working with paint products
b. safely apply paint to a blade surface to a specified layer thickness, and to be able to measure the layer thickness with a wet film gauge. The trailing edge section built in Lesson 19 can be used for this
