This invention discloses an integrated device and method for mercury vapor recovery and waste gas purification in amalgam brazing, belonging to the field of electronic packaging brazing and hazardous gas treatment. The device comprises a brazing sealing enclosure, a condensation unit, an iodine solution absorption unit, a sulfur absorption unit, a zinc powder absorption unit, and a safety monitoring module, connected in series. During brazing, mercury-containing waste gas is collected by the enclosure and first enters the condensation unit for pre-cooling and recovery of liquid mercury; then it enters the iodine solution absorption unit, where it reacts with iodine to generate mercuric iodide precipitate and capture silver dust; next, the residual mercury is fixed as mercuric sulfide by the sulfur absorption unit; finally, trace mercury is adsorbed by the zinc powder absorption unit. The purified waste gas is monitored in real time by a mercury concentration sensor; if the concentration exceeds the standard, an alarm is triggered and the heating platform is automatically shut down. This invention achieves a mercury removal rate of over 99.5% through four-stage synergistic purification, with emission concentrations lower than the national standard of 0.01 mg / m³. 3 It has advantages such as high purification efficiency, safety and reliability, good material compatibility, and convenient maintenance.

This invention relates to the field of pharmaceutical packaging technology and discloses a smart protective cap for dispensing alcohol and iodine solution. The cap includes a container for holding alcohol and iodine solution, a smart controller, a reminder display screen, and a self-resetting, press-to-deoxygenation component. The container includes a bottle body, a neck, and a smart protective cap for protecting the liquid inside the bottle. The neck is integrally connected to the top of the bottle body at the opening. The smart protective cap includes a sealing cap and a snap-on cap connected to the top of the sealing cap via an automatic flip-opening mechanism. A dispensing hole is provided near the front of the top of the sealing cap, and the inner wall of the snap-on cap has a leak-proof ring that abuts against the inner wall of the dispensing hole. The snap-on cap includes a first cover plate and a second cover plate. This application's automatic flip-opening mechanism replaces the traditional manual flip-opening method, solving the risk of cross-infection caused by manual operation. The built-in self-resetting, press-to-deoxygenation component effectively absorbs oxygen from the bottle, preventing oxidation and deterioration.

This invention discloses a biodegradable bio-based composite wound dressing and its preparation process, relating to the field of chitosan dressing processing technology. Chitosan powder is added to purified water and stirred for 60 minutes in a constant temperature water bath to fully dissolve and form a chitosan solution. Sodium carboxymethyl cellulose is added, and stirring continues until completely dissolved. After pH adjustment, glycerin and povidone-iodine solution are added sequentially, and stirring is continued for 20 minutes to ensure the system is homogeneous and free of sediment. The mixed solution is filtered through an 80-mesh filter to remove undissolved impurities, yielding a clear dressing precursor solution. This solution is then poured into a custom mold, pre-frozen in a low-temperature freezer, and then transferred to a vacuum freeze dryer for drying. After drying, a porous sponge-like preform is obtained. The dried porous sponge preform is flattened and fed into a slitting machine for cutting. After cutting, individual dressing pieces are collected, packed into medical polyethylene composite film bags, and sealed using a packaging machine. The packaging is sealed through a processing procedure, and then sterilized and ventilated to complete the process.
