Latest Patents

One of Jian Hu's latest patents is titled "Method for preparing fluff pulp from bamboos and fluff pulp prepared thereby." This invention discloses a method for preparing fluff pulp from bamboos, which involves treating the bamboos with high-concentration alkali at a relatively mild temperature. After a specific treatment period, the method replaces the treatment liquid for separating hemicellulose with a weak black liquor. The process continues with Kraft cooking the treated bamboos to obtain unbleached bamboo pulp, followed by removing rejects using a slotted screen and miscellaneous cells with a microporous sieve. The pulp undergoes two stages of oxygen delignification and ECF bleaching treatment of a DEpDP process, resulting in bamboo fluff pulp characterized by high whiteness, low DCM extract content, low ash content, and long fiber length, containing 4.2-4.6 million fibers per gram.

Another significant patent is the "One-step molded lithium ion battery separator, preparation method and application thereof." This invention provides a battery separator that comprises a support layer and a filler layer. The support layer includes superfine main fiber, thermoplastic bonded fiber, and first nanofiber, while the filler layer consists of inorganic fillers and third nanofiber. The lithium-ion battery separator has a thickness of 19-31 µm, a maximum pore diameter of no more than 1 µm, and a heat shrinkage rate of less than 3% after treatment at 300°C for one hour. This separator maintains strength at high temperatures, ensuring stability and isolation of the rigid structure of the filler layer, thus meeting the separator's requirements for heat resistance, pore size, and strength.
