This invention discloses a sterilizer, relating to the field of environmental treatment, comprising a main fan, a return air duct, a first outlet air duct, a vaporization chamber, and a second outlet air duct. The air inlet of the main fan is connected to the end opening of the return air duct, and the air outlet of the main fan is connected to the beginning opening of the first outlet air duct. The end opening of the first outlet air duct is connected to the air inlet of the vaporization chamber, and the air outlet of the vaporization chamber is connected to the beginning opening of the second outlet air duct. The vaporization chamber is equipped with a dual-fluid atomizing nozzle and a heater, and also includes a disinfectant storage tank, a metering pump, and an air pump. The inlet of the metering pump is connected to the disinfectant storage tank, the outlet of the metering pump is connected to the supply port of the dual-fluid atomizing nozzle, and the air outlet of the air pump is connected to the supply port of the dual-fluid atomizing nozzle. It achieves sterilization of the entire internal cavity without blind spots or dead angles, achieving a kill rate of up to 99.9999% for target microorganisms. It has a compact structure and strong versatility, and can be used for sterilization of closed equipment as well as room sterilization, meeting the relevant requirements of biosafety laboratories.

This utility model relates to the field of sterilization technology and discloses a tea substitute sterilization device. The device includes an installation plate with a support column fixedly installed at the bottom. A sterilization component, including a heat insulation pad, is mounted on the installation plate. To enhance the sterilization effect, the device incorporates a sterilization component. This component, in conjunction with a servo motor, drives a half-gear to rotate. Through the meshing of the teeth with a reciprocating ring, a limiting rod drives an L-shaped rod and an arc-shaped push plate to reciprocate within the sterilization chamber. The arc-shaped design of the push plate ensures the tea substitute is evenly agitated, preventing incomplete sterilization in certain areas. Simultaneously, a heating plate adheres to the bottom of the sterilization chamber, rapidly raising the temperature to a suitable level. Combined with ultraviolet irradiation from the sterilization lamp, this creates a synergistic effect of thermal and ultraviolet sterilization, improving the kill rate of microorganisms such as E. coli and mold.

This invention discloses a quaternary ammonium salt no-rinse disinfectant gel with skin-friendly properties. The quaternary ammonium salt no-rinse disinfectant gel contains the following raw materials and their weight parts: quaternary ammonium salt 0.1-0.5 parts, glycolipid surfactant 0.02-0.3 parts, gel matrix 0.5-1 parts, pH adjuster 0.1-0.5 parts, and deionized water 97-99.3 parts. The formulation of this invention is characterized by quick-drying, refreshing and odorless, non-toxic and harmless, and mild.

This invention discloses an antibacterial and wound-healing photosensitizer, its preparation method, and its applications. The photosensitizer of this invention has a core-shell structure, with the core being MIL-88B modified with amino / bromodiphenyl ligands embedded in silver nanoparticles, and the shell being MIL-88C grown in situ on the core surface. The photosensitizer of this invention significantly improves the photogenerated carrier separation efficiency and reactive oxygen species generation capacity through its MOF-on-MOF heterostructure. Under light irradiation, it exhibits highly efficient killing effects against Staphylococcus aureus, Escherichia coli, and methicillin-resistant Staphylococcus aureus, while also possessing good biocompatibility, promoting fibroblast migration, and showing significant hemostatic and wound-healing effects. This photosensitizer has broad application prospects in the preparation of photodynamic antibacterial drugs and wound-healing medical materials.

The present application relates to a kind of attractant, insecticidal gum bait and brush type insecticide, it is related to daily chemical technical field.The attractant includes at least one of caryophyllene, 1, 3-dihydroxypropanone or 2-amino-3-methylbutyric acid.The attractant is colorless and transparent and has good fluidity, has strong attractant to cockroach, using the attractant can be prepared to obtain the appearance transparent insecticidal gum bait, to solve the problem that conventional bait has color, leading to ground, wall is not beautiful.The insecticidal gum bait can be distributed in many places by the way of brushing, not only can be film-formed in ground, wall and other areas, make drug component adhere to the surface of application area, but also can be washed clean afterwards, improve the convenience of use, and compared with conventional bait box, gum bait, granular point distribution mode, has higher killing rate to cockroach or other pests, provide a kind of new insecticidal gum bait product.

This invention belongs to the field of water treatment and discloses a sludge treatment antibacterial conditioner, its preparation method, and its application. The conditioner improves sludge dewatering performance by adding polyaluminum ferric silicate as an inorganic flocculant for charge neutralization and destabilization, and adsorption bridging; it also incorporates plant enzymes to destroy bacterial structures for sterilization; and wood ash and straw form a rigid skeletal support structure. This invention forms a triple sterilization defense line, achieving high kill rates of common pathogens and high parasite egg mortality. Through the charge neutralization of polyaluminum ferric silicate, the cell wall disruption of extracellular polymers by compounded plant enzymes, the skeletal support system constructed by wood ash and straw, and the multiple dewatering processes via polyquaternary ammonium salt adsorption bridging, the sludge moisture content is reduced, lowering the costs of subsequent sludge transportation, disposal, and utilization. Using natural plant extracts and agricultural waste as the main functional components replaces components in traditional chemical conditioners that easily produce toxic byproducts, the treated sludge can be directly used for land application or landscaping, making it environmentally friendly.
