The present application relates to the technical field of collagen, in particular to a kind of active collagen lyophilized preparation and its preparation method and application.The preparation method includes the following steps: S1, the aqueous solution of freeze-drying protective agent is prepared;S2, the initial emulsion of active collagen is diluted with physiological saline, to obtain the first solution, then mixed with the aqueous solution obtained in step S1, to obtain the second solution;S3, the second solution obtained in step S2 is added to the aqueous solution of step S1, and the third solution is prepared after mixing and emulsifying, to obtain mixed emulsion;S4, the mixed emulsion in step S3 is filled and freeze-dried, wherein the freeze-drying protective agent includes glycine, and the concentration of active collagen in the third solution is 5-15 mg / mL.The lyophilized preparation prepared by the preparation method has excellent reconstitution effect, and is convenient for transportation and storage.

The utility model relates to the field of 3D printing, in particular to plastic additive powder anti-agglomeration mixing equipment which comprises a bottom plate, a lifting assembly is arranged on the bottom plate, and a mixing assembly is arranged on the lifting assembly; according to the anti-agglomeration mixing equipment for the plastic additive powder, through the arrangement of the mixing assembly, the scheme adopts a multi-motor cooperative driving composite motion mechanism, a second motor drives a stirring frame to realize shearing and convection dispersion of materials in a barrel, and a first motor drives a rotating frame and the mixing barrel to rotate, so that space migration and collision of the materials are enhanced; the third motor enables the rotating frame to rotate reversely through the chain wheel and the transmission chain, and a multi-dimensional complementary movement track is formed. The multi-shaft linkage mode effectively breaks through the limitation of traditional single-shaft stirring, the dispersion efficiency and uniformity are remarkably improved, and the agglomeration phenomenon is efficiently eliminated by strengthening friction and collision among particles, so that the mixing quality of the plastic additive powder is ensured to meet the high-standard process requirement.

The application discloses a high-adhesion ink composition and a preparation method thereof, which comprises a polyurethane core-shell hybrid resin, a binary chlorovinyl resin, a bio-based mixed solvent, an inorganic mixed pigment composed of titanium white and barium sulfate, and a hybrid resin film layer with a mass fraction of 3-8% on the surface of the inorganic mixed pigment. The application adopts low-VOC bio-based raw materials, the bio-carbon content is greater than or equal to 60%, the ISCC low-carbon certification is met, and the ink is biodegradable. The core-shell hybrid resin and the binary chlorovinyl resin are synergistically film-formed, and the coating pull-off adhesion is good. The titanium white and the barium sulfate are compounded at a ratio of 1:1 and are pre-coated and modified, so that pigment aggregation is avoided, the ink dispersion fineness is less than 8.0 microns, and the cost is effectively controlled. The ink coating-4 cup outflow time is less than 35 seconds. The glass beads with a diameter of 2-3 mm are used for grinding, the process is simple, the raw materials are easy to obtain, batch production is suitable, and the application can also be used for high-end environmental protection printing of plastic film.
