Method for manufacturing bicycle wheel |
摘要 |
The bicycle wheel manufactured by the method of the present invention is made of composite material and has two opposite braking surfaces, each of which is coated with a fluoride polymer layer. Specifically, the braking surfaces are sand blasted to remove a releasing agent layer coated on the wheel. The wheel is, thereafter, placed in a spraying machine at about 100 degree Celsius and then the braking surfaces are spray-coated with a material selected from the group consisting of polytetrafluoro ethylene, fluoride ethylene-propylene copolymer, polyfluoroalkyl, ethylene-tetrafluoro ethylene copolymer and the mixture thereof until a thickness of the material is bigger than 0.4 cm. Thereafter, the wheel is gradually heated to make the material set and form the fluoride polymer layers. |

1. A method for manufacturing a bicycle wheel, the wheel being made of composite material comprising carbon fiber, glass fiber, or Kevlar fiber, and having two opposite braking surfaces, the method comprising:
sand blasting the braking surfaces to remove a releasing agent layer coated on the wheel; polishing the braking surfaces to become smooth; heating the wheel to about 100° Celsius in a spraying machine; spray-coating the braking surfaces at least twice with a heated spray material selected from the group consisting of polytetrafluoro ethylene, fluoride ethylene-propylene copolymer, ethylene-tetrafluoro ethylene copolymer, and mixtures thereof until a thickness of the material is bigger than 0.4 cm, wherein the spray material is heated to 100° Celsius before spray-coating onto the braking surfaces; and gradually heating the wheel to at most 180° Celsius to set the spray material and form fluoride polymer layers. |
