High-strength glue refers to glue with high bonding strength after curing. Among the glues we usually come into contact with the most, there are probably these types of glues with relatively high strength:
1. Epoxy adhesives
p>Epoxy adhesives have high bonding strength to polar materials such as stone, metal, and wood. They can be used as reinforcement glue, blades for wind power generation, and other places that require high bonding strength. However, epoxy adhesives The adhesive has little elasticity after curing. Of course, modified epoxy can improve the elasticity, but the bonding strength will decrease.
2. Acrylic AB glue
Acrylic AB glue has a good bonding effect on polar materials such as stone, metal, and wood. It is also suitable for some products with solubility parameters close to ABS. For the bonding of plastics, the shells of many electronic products are bonded with acrylic AB glue. After curing, the glue layer has a certain degree of toughness, so its impact resistance is better than that of epoxy adhesives.
3. Polyurethane adhesive
Polyurethane adhesive has good adhesion to many materials such as stone, metal, wood, and some plastics. It can be prepared with different hardness according to different formulas. Polyurethane adhesive has a wide range of applications. Polyurethane adhesive has relatively good wear resistance and relatively high bonding strength.
What is the spine inside the wind turbine blade?
The wind turbine blade is one of the core components of the wind turbine, accounting for about 15% to 20% of the total cost of the wind turbine. , the quality of the design will be directly related to the performance and benefits of the fan. Wind turbine blades are the core components in wind turbines that convert wind energy into electrical energy. The size and shape of the blades determine the energy conversion efficiency, and also directly determine the power and performance of the unit. Wind turbine blades are at the core of wind turbine design and are the most expensive parts of the entire machine. Wind power blades account for 20% to 30% of the total cost of the overall wind power system. 80% of the total cost of domestic blades comes from raw materials, with reinforced fibers and matrix resin accounting for more than 60%, and adhesive glue and core materials each accounting for more than 10%.
Wheels. The hub is the hub of the wind wheel and the connection between the blade root and the main shaft
The wind turbine is mainly composed of three parts: the impeller, the nacelle, and the tower. Since the tower is usually tendered separately during wind farm bidding, the wind turbine generally refers to the impeller and the nacelle.
The impeller of the wind turbine is responsible for converting wind energy into mechanical energy and consists of blades, hubs and fairings. Among them, the blades convert the kinetic energy of the air into the mechanical energy of the blades and main shaft, and then into electrical energy through the generator.
Wind turbine blades are the core components in wind turbines that convert wind energy into electrical energy.
The size and shape of the blades determine the energy conversion efficiency, and also directly determine the power and performance of the unit. Therefore, wind turbine blades play a core role in wind turbine design and are also the most expensive parts of the entire machine.
Wind power blades account for 20%-30% of the total cost of the overall wind power system. At present, 80% of the total cost of domestic blades comes from raw materials, among which reinforced fiberThe base resin accounts for more than 60%, and the adhesive glue and core material each account for more than 10%.
