This invention relates to the field of polymer materials technology, specifically disclosing an environmentally friendly processing aid for polyolefins and its preparation method. The environmentally friendly processing aid for polyolefins includes a first component and a second component. The first component includes an antioxidant-modified oligomer A, and the second component is obtained by extrusion granulation of oligomer B, an organosilicon polymer, and a catalyst. By weight, the amounts of each component are: oligomer A 1-10 parts, antioxidant 0.1-2 parts, oligomer B 5-40 parts, organosilicon polymer 5-80 parts, and catalyst 0.1-5 parts. The processing aid of this invention does not contain perfluorinated or polyfluoroalkyl compounds. When used in the processing of polyolefins, it has advantages such as low addition amount, short onset time, good viscosity reduction effect, and effective improvement of product gloss. Furthermore, it can effectively form a dynamic lubricating layer on the surface of metal walls.

This utility model proposes a dual-function enclosure for fire protection and elevator locking. The enclosure includes a back panel, an outer shell liner, and an outer shell. The outer shell liner and outer shell are assembled to form a shell structure. The back panel is fixed to a surface adjacent to the control cabinet, and the shell structure is fixedly connected to the back panel. A fire switch and an elevator locking switch are installed within the shell structure. The fire switch communicates with the fire protection system. Both the fire switch and the elevator locking switch have lead-out wires, which are combined into a single cable bundle and connected to an adapter plug. The adapter plug connects to a cable and communicates with the elevator control system. The signals from both switches are led out through wires, bundled together, and connected to the adapter plug. The cable is then connected to the elevator control system via the adapter plug, realizing the elevator's fire protection and elevator locking functions.

The application discloses a nystatin solution and a preparation method and application thereof, which is prepared from the following raw materials in parts by weight: nystatin 20-50 parts, dimethyl sulfoxide 110-220 parts, preservative 1.5-2.0 parts, antioxidant 0.5-1 part and 1,2-propylene glycol 737-880 parts. The application creatively adopts a composite solvent system of dimethyl sulfoxide and propylene glycol, utilizes the extremely strong dissolving capacity of dimethyl sulfoxide and the auxiliary solubilization and dilution effect of propylene glycol, and produces a significant synergistic effect. The system can completely dissolve up to 50 parts by weight of nystatin, forms a clear, transparent and uniform stable solution, fundamentally solves the technical bottleneck that nystatin cannot be prepared into a high-content solution due to poor water solubility, and lays a foundation for poultry group water medication.
