The present invention discloses a 3D core material weaving device, which belongs to the technical field of manufacturing 3D woven composite floors for rail transit vehicles. The present invention comprises a bracket; a core material clamping mechanism, which is arranged on the bracket, and the core material clamping mechanism has a core material bracket for fixing the core material; a weaving mechanism, which comprises a movable walkway that can be displaced, a workbench and a turntable wiring platform that are slidably connected to the movable walkway and move perpendicularly to the displacement direction of the movable walkway; and a second motor that drives the workbench and the turntable wiring platform to move, wherein a first motor that drives the movable walkway to be displaced is fixedly connected to the bracket, and a third motor that drives the fiber line to be routed is fixedly connected to the turntable wiring platform; and also comprises a needle mechanism fixedly connected to one side of the turntable wiring platform, which is used to pierce the fiber line of the weaving mechanism into the core material. The core material woven by the present invention has a delicate and uniform appearance and a high pass rate, thereby realizing efficient and accurate weaving of the core material, and the operation is simple and easy to use.

The invention relates to the technical field of rubber modification, in particular to a fluororubber-ethylene propylene diene monomer compatilizer and application. Silica (DMSN) with a dendritic mesoporous structure is synthesized and can be physically located at a two-phase interface, the effects of anchoring and reinforcing the phase interface are achieved, the size of a phase region is prevented from being too large, and therefore the compatibility is preliminarily improved. PFTS is further used for carrying out surface grafting modification on DMSN, PFTS is grafted to the surface of silicon dioxide through Si-O-Si, the compatibility of a perfluoro long chain at the other end and an FKM phase is good, and the interface bonding force between the filler and a rubber matrix is remarkably enhanced. The finally obtained composite material not only has the inherent high temperature resistance, oil resistance and chemical resistance of FKM, but also improves the low temperature resistance due to the introduction of EPDM, and greatly enhances the mechanical strength and toughness due to the enhancement of PFTS-DMSN.

The invention discloses iguratimod gel and a preparation method thereof. In the disclosed gel, iguratimod is dissolved in light liquid paraffin, and the light liquid paraffin, a water-based gel matrix carbomer and a pH regulator are stirred, homogenized and dispersed to form milk white gel which is uniform and fine in texture. The Iguratimod gel disclosed by the invention is simple and feasible in process, stable in property, relatively good in reproducibility, very good in extrusion performance, easy to coat and use, free of local irritation, and convenient and rapid in clinical application.

The invention relates to a polyethylene glycol matrix preparation and a preparation method thereof. The method comprises the following steps: 1) determining prescription dosages of raw material medicines, polyethylene glycol 3350 and / or polyethylene glycol 4000 and polyethylene glycol 400; 2) melting the substrate; 3) cooling the substrate; (4) preparing a raw material medicine polyethylene glycol 400 suspension; (5) preparing ointment; (6) homogenizing; and 7) cooling the paste, and optionally, the method further comprises the steps of standing the paste in the step 7) overnight, and heating and stirring the paste in the second day. Once the polyethylene glycol matrix preparation prepared by the method disclosed by the invention is produced, the polyethylene glycol matrix preparation can reach a composite stable state and presents a peak at 30-60 DEG C in DSC (differential scanning calorimetry), that is, the paste is in a single-phase state, is a stable product, does not change with time or temperature, is fine and smooth in appearance, does not have a gravel feeling, and is good in skin feeling experience of a user.

A method for preparing a binary formula for Dai pottery clay and its application is disclosed. The method involves taking Dai pottery clay from the Honghe River basin, five-colored clay from Honghe County, and charcoal powder. The Dai pottery clay and five-colored clay are sun-dried and weathered for at least three months. The Dai pottery clay from the Honghe River basin has a SiO2 content of not less than 50%, an Al2O3 content of not less than 15%, an Fe2O3 content of not less than 10%, and a loss on ignition of less than 10%. The five-colored clay from Honghe County has a SiO2 content of 72-82%, an Al2O3 content of 9-12%, and an Fe2O3 content of 3-5%. The method involves soaking the Dai pottery clay and five-colored clay in water until fully saturated, then ball-milling them. The slurry is sieved, and then charcoal powder is added. After stirring evenly, the clay is pressed to drain water and then kneaded to remove air. This invention can improve the throwing and molding performance of Dai pottery clay, increase the sintering temperature and the density and strength of its structure, and reduce the burn-off rate.

The application discloses a knitted belt with elastic covered yarn as floating threads, which comprises a belt body, the belt body comprises a pile layer, a weft layer and a root layer which are connected by integral knitting, the pile layer is located on the surface of the belt body, the weft layer and the root layer are located inside the belt body, and the root layer is arranged between the pile layer and the weft layer, the root layer is connected with the pile layer and the weft layer respectively, and the pile layer is formed on the surface of the belt by knitting with elastic covered yarn in the process mode of floating threads. The pile layer is formed on the belt body by adopting the elastic covered yarn and the process mode of floating threads, so that the problem that the traditional knitted belt cannot consider the hand feeling and the anti-pilling property when pursuing high modulus demand is solved.
