This invention provides a hot-press forming method for optical glass elements that prevents glass preforms from sticking to molds. The method includes the following steps: depositing a boron nitride film layer on the surface of a glass preform, and then hot-pressing to form an optical glass element. The thickness of the boron nitride film layer on the surface of the glass preform is less than or equal to 15 nm. The surface of the hot-pressed optical glass element is coated with at least one atomic layer of boron nitride film, or at least 0.65 nm thick boron nitride film. This invention solves the glass adhesion problem by depositing a boron nitride film layer on the surface of the glass preform, preventing fusion, cracking, and other defects. Using PVD or CVD boron nitride film layers prevents active hydrogen from hydrogen-containing DLCs from entering the glass preform during film formation, preventing fogging, blurring, and damage to the film surface of the optical glass element. It also reduces the difficulty of mold separation during the molding process and improves production automation and molding stability.

This utility model relates to the field of chemical experimental equipment technology, specifically to a laboratory feeding device. The feeding device is characterized by comprising a mounting frame, which includes a lower material tray support and an upper feeding support. A feeding bottle is mounted on the material tray support, and a reaction vessel is connected below the feeding bottle. The feeding bottle includes a solid material bottle, and a discharge port is provided at the lower end of the solid material bottle. A solid feeding mechanism is provided on the feeding support, and the solid feeding mechanism includes a vertical drive mechanism. A vibration mechanism is provided at the lower end of the vertical drive mechanism. The vertical drive mechanism drives the vibration mechanism to move downward to contact the solid material bottle, causing residual material inside the solid material bottle to vibrate and fall off. The vibration mechanism enables vibratory feeding, causing material adhering to the walls of the solid material container to fall off, ensuring smooth material feeding and guaranteeing experimental efficiency and quality.

The invention discloses a high-water-content bionic noodle making process and equipment. Flour and water are mixed in a bionic kneading dough maker in proportion, and dough is obtained after a starch gluten network is reconstructed; performing extrusion forming on the dough to obtain a dough strip I; overlapping at least two layers of dough strips I, and performing multi-dimensional three-dimensional kneading and rolling treatment according to a set rolling ratio to obtain dough strips II; placing the dough strip II in an air-isolated environment, and performing moisturizing static long-time fermentation treatment to obtain a dough strip III; performing step-by-step double-sided rolling and thinning on the dough band III to obtain a dough band IV; performing dough beating and rolling treatment on the dough strip IV to obtain a dough strip V; rolling the noodle belt V, cutting into strips, and performing anti-sticking diffusion treatment on noodle threads to obtain noodles; the equipment sequentially comprises a bionic kneading dough kneading machine, a dough strip forming machine, a rolling and kneading composite rolling machine, a moisturizing static long-time fermentation machine, a double-layer rolling and kneading machine, a dough beating and calendering machine and a calendering, slitting and diffusing integrated machine, the technical problem of non-large-scale industrial production of dough kneading and fermentation with high water content is solved, and the quality of noodles is improved.

This invention discloses an anti-swelling asymmetric hemostatic dressing, comprising two layers: an upper layer of highly adhesive hydrogel and a lower layer of non-adhesive hydrogel. The anti-swelling asymmetric hemostatic dressing is prepared by first adding a non-adhesive solution A to a mold and photocuring it, then adding a highly adhesive solution B and photocuring it again. The dressing of this invention, with its highly adhesive hydrogel upper layer and non-adhesive hydrogel lower layer, possesses both adhesive and anti-adhesive properties. Furthermore, the hydrogel is anti-swelling, enabling rapid hemostasis within 10 seconds, easy peeling, and promotion of wound healing.
