Belzona 5721 Lep Solution For Cold Weather

 
 

Отрасли промышленности:

Power (POWR)

 
 

Применения:

 
 

Местоположение клиента:

Wind Farm, Minnesota

 
 

Дата применения:

September 2019

 
 

Ситуация применения:

Leading Edge Protection solutions need higher temperatures to properly be applied and cured. As temperatures dropped towards 40°F (4.4°C) there are not many solutions out there which will work.

 
 

Проблема:

Over time, the leading edge of wind turbine blades become eroded and lose efficiency and power production for the turbine generator.  Because of the time of year, the weather was very cold, and a blade repair solution was needed to properly complete the repairs.

 
 

Продукты:

Belzona 5721

 

Подложка:

Fiberglass/Gelcoat

 
 

Метод применения:

The application was carried out in accordance with a modified version of Belzona Know-How System Leaflet FBC-1. The blades were coated on the turbine at the operation site. The pitting and loss of surface on the leading edge was resurfaced with a filler product and rebuilt to dimensions. The surface area was sanded down with a mechanical sander and cleaned with a rag and non-residual solvent cleaner. One coat of Belzona 5721 at 20 mils (508µm) was applied.

 
 

Факты Belzona (Экономия средств? Альтернативы? Почему Belzona?, и т.д.):

The work was completed by the contractor thanks to Belzona 5721 as they could not normally apply LEP coatings on the blades at this time of the year. It saved the customer time as the coating cures in 6 hours, therefore downtime was substantially reduced.
