The invention discloses a method for performing three-dimensional printing on a biological ceramic bracket based on light-cured molding. The method comprises the following steps: firstly, mixing biological ceramic, a biological glass sintering aid and resin premixed liquid uniformly to obtain photosensitive ceramic slurry; putting the photosensitive ceramic slurry on light-cured molding equipment, and performing three-dimensional printing on a biological ceramic bracket green body according to a three-dimensional model which is input into a forming machine; drying, degreasing and sintering the biological bracket green body to obtain the biological ceramic bracket. The biological ceramic bracket has the following characteristics: the three-dimensional size is not limited, the strength is high, 100 percent of three-dimensional holes are communicated, and the hole structure is accurately controllable, and the application prospect in the field of a bone defect repairing material is good.

The invention discloses an infinite-arbitrary-length bamboo chip integrated material. The infinite-arbitrary-length bamboo chip integrated material is formed by a plurality of lengthened bamboo chipswhich are glued and overlaid; each lengthened bamboo chip is formed by a plurality of bamboo chip units which sequentially and continuously mesh and are connected in a butt joint mode; sharp teeth andgrooves are formed in the two ends in the length direction of the bamboo chip units, wherein the sharp tooth of each bamboo chip unit and the groove of the corresponding bamboo sheet unit are matchedto form a meshing butt-joint part, and the meshing butt-joint parts of the adjacent lengthened bamboo chips are arranged in a staggered mode; and the thickness of the bamboo chip units is 4-12 mm, and the width of the bamboo chip units is 15-50 mm. The invention further provides a manufacturing method of the bamboo chip integrated material. The manufacturing method comprises the steps of preparation of the bamboo chip units, meshing butt-joint, hot-pressing gluing and the like. The infinite-arbitrary-length bamboo chip integrated material and the manufacturing method thereof have the advantages that connectors are small, the mechanical strength is uniform, and the infinite-arbitrary-length bamboo chip integrated material is suitable for structures such as van truck bottom plates.

The invention relates to an activated carbon fiber and a preparation method thereof. The compositions in weight percentage of the activated carbon fiber are: 80 to 95 percent of fiber-forming polymer, and 20 to 5 percent of functional additive component, wherein the fiber-forming polymer can be polyacrylonitrile, modified polyacrylonitrile, polyvinyl alcohol or regenerated cellulose fiber; and the functional additive component can be a superfine absorbent of supporting metal with the average diameter of between 0.01 and 20 mu meter; and the supporting metal can be one of a silver ion, a copper ion or a zinc ion. The preparation method comprises the following steps: a base material fiber-forming polymer fiber containing the functional additive component is prepared first, wherein the base material fiber can be a polyacrylonitrile fiber, a modified polyacrylonitrile, a polyvinyl alcohol fiber or a regenerated cellulose fiber base fiber; and different physical activation treatments or / and chemical activation treatments are carried out according to different base material fibers to produce the activated carbon fiber corresponding to the base material.

The present invention discloses mordenite having diatomite morphology and a multi-level pore channel structure, and a preparation method thereof. According to the present invention, cheap diatomite having an unique macroporous structure is adopted as a zeolite preparation template and a silicon / aluminum source, and during the preparation process, a diatomite-porous carbon intermediate is prepared, and then porous carbon is adopted as a template and diatomite is adopted as a silicon source and an aluminum source to prepare the porous mordenite having the diatomite morphology and the large / micro pores. According to the present invention, the obtained mordenite has the diatomite morphology and further has the high macroporosity so as to provide the multi-level pore channel structure, such that the efficient adsorption is provided; and compared with the mordenite processes through other template methods, the method of the present invention has characteristics of simple process and low potential environment hazard.
