A method for using ganoderma lucidum liquid fermentation liquor to prepare feed and feed additive containing ganoderma lucidum active ingredient, pertains to the field of biofermentation and feed. The invention includes steps of: a. centrifugally separating the ganoderma lucidum liquid fermentation liquor at 5000 per-minute to obtain the ganoderma lucidum fermentation supernatant and ganoderma lucidum residues; b. adopting a rear spraying process to mixing the ganoderma lucidum fermentation supernatant with the feed in a proportionality of adding 0.5-1.5 ml of the supernatant in the feed for preparing feed containing ganoderma lucidum active ingredient; c. performing a second fermentation to the ganoderma lucidum residues for preparing the feed additive containing ganoderma lucidum activeingredient. The invention fully use the ganoderma lucidum fermentation liquor, has no waste water and waste slag discharge, simple steps, low cost, and easy large-scale industrialization. Products are rich in Ganoderma lucidum polysaccharides and ganoderma lucidum acid; have a balance immune system, and antibacterial, antiviral, anti-parasitic, anti-tumor, anti-radiation and the like extensive physiology activities, thereby largely improving the immune disease resistance, maintaining the animal intestinal health, and further improving the production performance and market efficiency of animals.

The invention discloses a vinylene carbonate-based lithium ion battery polymer electrolyte and a preparation method as well as application thereof in a room-temperature full-solid lithium ion battery. The vinylene carbonate-based lithium ion battery polymer electrolyte comprises vinylene carbonate or a copolymer of vinylene carbonate, lithium salt, a porous backing material and an additive, wherein the molecular weight of a vinylene carbonate-based polymer is 172-1*10<7> Da; the ionic conductivity of the vinylene carbonate-based polymer electrolyte is 1*10<-3>-1*10<-5>S / cm at 25 DEG C; the initial decomposition voltage range is 4.5-5.2 V vs.Li<+> / Li. The vinylene carbonate-based electrolyte is prepared by the in-situ polymerization method, so that the electrolyte has excellent interfacial compatibility with electrodes. The vinylene carbonate-based polymer electrolyte can be used in the room-temperature full-solid lithium ion battery; the vinylene carbonate-based polymer electrolyte is excellent in electrochemical oxidation reduction stability, and can be used in high voltage resistant polymer electrolyte materials. The invention further provides the preparation method of the vinylene carbonate-based lithium ion battery polymer electrolyte, and a lithium ion battery made of the electrolyte.

The invention provides a preparation method of high-purity spherical full-pore silica gel particles. The method is carried out according to the following steps of: hydrolyzing, polymerizing in advance, distilling, preparing a water phase, preparing an oil phase, synthesizing particles and grading. In the invention, ethyl orthosilicate is used as a raw material, silica sol with high concentration (which is greater than 90wt%) is obtained by hydrolyzing and polymerizing in advance under an acidic condition, and the yield is enhanced; the formula of emulsion is optimized through a method of emulsion polymerization by adopting a compounded surfactant, the stability of the emulsion and the monodispersity of liquid drops are enhanced, the agglomeration and the shape deformation of the particlesare avoided, and water is adopted as a reaction medium, which adapts to the requirement of environmental protection; in the preparation of the particles, a pore structure is naturally formed without burning organic components at high temperature to obtain a porous structure, which is simple, convenient and effective and protects the environment; the entire method has simple procedure, excellent repeatability and low cost; and the obtained material has high purity, good mechanical strength, uniform particle diameter, controllable size and narrow and controllable pore diameter distribution.

The invention relates to a method for preparing a high-purity tantalum target for electronic materials, which belongs to the field of powder metallurgy and semiconductor device manufacturing. The preparation method is to pulverize a high-purity tantalum block first, and then ball mill it to a particle size of 5-150 μm. Tantalum powder; after mixing the tantalum powder, install the mold, vibrate and compact; then put the mold into a high-temperature hot-press furnace, and press at 1500-1800°C; after sintering, cool to room temperature and release the furnace to obtain high-purity Green body of tantalum target, density 11.3‑14.5g / cm 3 . According to the requirements of the magnetron sputtering equipment, the green body is cut and processed, and the processed green body is welded to the corresponding back plate according to the user's requirements to obtain a high-purity tantalum target. The high-purity tantalum target prepared by the present invention can significantly reduce the technical difficulty of preparing the target by the traditional casting method, greatly improve the controllability of the process, and contribute to the improvement of the coating performance of later materials.
