  • Patent number: 9868234
    Abstract: A method for manufacturing a carbon fiber component includes: placing a film with a texture on a first side surface into a mold, where a second side surface of the film abuts against an inner wall of the mold; injecting melted carbon fiber composite plastic into the first side surface through an injection port of the mold to obtain a component in a first shape; and obtaining a component in a second shape from the component in the first shape by using a material removal technique. Compared with the prior art, with the manufacturing method provided in the present invention, on the basis of ensuring a use strength requirement of a component, processing efficiency may be effectively increased. On this basis, the present invention further provides a carbon fiber component manufactured by using this manufacturing method.

  • Patent number: 9695125
    Abstract: The present invention provides a method for synthesizing cationic bleach activators via a single-bath reaction, comprising steps of: separately dissolving 4-chloromethylbenoyl chloride and lactam in its respective solvent, adding an acid-binding agent to the lactam solution, next adding dropwisely 4-chloromethylbenoyl chloride solution into the lactam/acid binding-agent solution, and finally adding tertiary amine to the solution above to make a reaction solution, which is further treated with mixing and refluxing. The washed and dried final product is TBLC cationic bleach activator. The method of the present invention greatly simplifies the synthesizing process and lowers the stringency of reaction conditions for preparing cationic bleach activators (TBLC). At the same time, the present method produces TBLC cationic bleach activators with high yields, making it a suitable option for industrial production of these bleach activators.
