Product Detailed

Detailed Product Description


  The features of the blade and FRP wind turbine blade

1.Under the condition that the centrifugal load is 15000N and the wave load is 850N

 Then the blades can not  happened to fracture and other damage.

2. The material used in blades has qualified certificate provided by vendor, chemical composition and mechanical  properties are in line with national standards.

Blades length Tolerance

±0.13%×Lmm

L means blades length

Blades Surface chord tolerance

±1.5%×cmm

C means the length of blades surface chord

Blades Surface thickness tolerance

±1%×tmm

t means the most thickness of blades surface

Blades Surface torque angle tolerance

±0.4°

The weight tolerance of Blades

±1%

The focus tolerance of blades axial

±10mm

3. The Blades can Normal and Efficient work for 24 hours even In harsh environments . In the environment that the temperature is from -50 to +50 and Humidity is below 95% ,the blades no trailing edge cracking, damage and other phenomena, The life of blade  can last 15 years, even more .

4. Blade surface is treated by high-quality Gel coat resin , so that the blades have  better  Moisture resistance,abrasion resistance, water absorption, high elasticity and anti-ultraviolet radiation and so on .

5. We use the technology resin filled in the process of laminating blade .so the blade have good performance of anti rotting cloud. It have good anti moisture and anti aging performance in the curing condition. Then so can give the blade two kinds of protection.

6. The proportion of resin packing less than the weight of 12%,(include up to 15% of the Thixotropic agent ),   The proportion of Thixotropic agent less than the weight of 3%

7. Pigment make use of modern organic dyes that it doesnt easily fade ,  by the  environment and climate  effect is very small, the color of the blades can long last bright and luster.

8. The petiole of the blades is bonding with the particular technics material, seem like nature itself. By carefully cleaning, wiping off oil ,to strengthen sunits ,making a suitable surface condition to achieve  the pursuit of high-performance connection.
