This invention discloses a high-gloss antibacterial ceramic glaze and its preparation method, relating to the field of ceramic glaze technology. By weight, its raw material composition includes: 75-85 parts of base glaze, 8-10 parts of antibacterial system, 6-10 parts of nucleating agent, 3-8 parts of colorant, 1.5-3 parts of auxiliary agent, 0.2-1.5 parts of functional additive, and 0.5-1.5 parts of nano-glossing agent. The functional additive is a compound of graphene quantum dots, quaternary ammonium salt modified montmorillonite, and rare earth carbonates in a weight ratio of (0.02-0.08):(0.1-0.3):(0.1-1). This ceramic glaze achieves a balance of high gloss, efficient and long-lasting antibacterial effect, and excellent glaze quality.

The invention provides a preparation method for extracting bamboo reed cellulose and MXene composite regenerated fibers based on oxidation-ultrasonic coupling, and belongs to the field of biomass-based functional fiber materials.The preparation method comprises the steps that after bamboo reed raw materials are cooked, the pH value of a system is adjusted, the liquid carrying rate is controlled, oxidation and ultrasonic pretreatment is conducted, the raw materials are purified, and the bamboo reed cellulose and MXene composite regenerated fibers are obtained; bamboo reed cellulose is obtained; a composite solution system is adopted for dissolving the spinning solution, and a uniform spinning solution is prepared; the preparation method comprises the following steps: uniformly dispersing MXene in a spinning solution in proportion, and preparing the bamboo reed-based MXene composite regenerated cellulose fiber by taking a buffer solution as a coagulating bath and adopting wet spinning. The invention solves the problems of high energy consumption, large reagent dosage, low yield and easy damage of cellulose structure in the existing bamboo reed cellulose extraction, and the problems of insufficient cellulose purity, poor MXene dispersity, poor interfacial compatibility, poor spinning solution stability and forming effect and the like in the MXene composite regenerated fiber preparation.

The application discloses a kind of stable indometacin tablets and its preparation process, belong to pharmaceutical preparation technical field.The tablet is composed of indometacin, hydroxypropyl beta-cyclodextrin, soybean phospholipid, composite stabilizer, binder and lubricant, and the composite stabilizer is compounded by succinylated c14-c18 alkyl sulfonate sodium, N-ethyl-L-glutamine and maltodextrin according to specific mass ratio.Preparation process includes liposome inclusion compound preparation, mixing granulation, drying whole particle, total mixing and tabletting.The application realizes the preparation of high drug loading design, and the composite stabilizer forms a multilayer coating protection system with hydroxypropyl beta-cyclodextrin and soybean phospholipid, which synergistically improves the dissolution performance and stability of the preparation, makes the dissolution rate of the preparation fast, and the content of the main component decreases little during long-term storage, solves the problems of low drug loading, poor stability and dissolution of existing indometacin tablets.

The invention relates to an antibiotic-free biological fermentation compound feed for poultry and a preparation method thereof, and belongs to the technical field of feeds, the feed takes a fermentation basic raw material as a carrier, plant extracts and chemical addition components are added, and the synergistic effects of resisting bacteria, diminishing inflammation, regulating intestinal flora, promoting nutrient absorption and improving the immunity of poultry are achieved in a biological fermentation synergistic manner; and antibiotic residues are avoided, so that the safety of poultry products is guaranteed.
