The invention belongs to the technical field of functional fiber materials, and discloses a compound deodorizing, antibacterial and antiviral multifunctional fiber and a preparation method thereof. Add PVA and organic silicon quaternary ammonium salt antibacterial agent to the antiviral extract of traditional Chinese medicine to obtain a mixed solution, and then add catalyst and sodium silicate or silicate compound for condensation reaction to obtain coated antiviral components of traditional Chinese medicine and organic silicon quaternary ammonium PVA‑SiO for Salt Antimicrobials 2 The interpenetrating network particles are mixed and spun with the obtained functional particles and fiber matrix to obtain the product. The present invention uses PVA as the coating agent of traditional Chinese medicine antiviral composition and organosilicon quaternary ammonium salt antibacterial agent, promotes its mixing and dispersing in fiber matrix; And further with SiO 2 An interpenetrating network reinforcement structure is formed. Introducing it into the fiber matrix can achieve long-lasting deodorizing, antibacterial and antiviral effects and enhance fiber strength.

The invention provides a cleaning and discharging movable multi-toilet-cubicle WC system assembly. The system comprises ten subsystems, namely a toilet cubicle use subsystem, a wind source subsystem, an excrement collection subsystem, a solid-liquid separation subsystem, a microwave incineration subsystem, an electrodeless photocatalysis urine treatment subsystem, an electrodeless photocatalysis waste gas treatment subsystem, a heat exchange subsystem, a reclaimed water recycling toilet flushing subsystem and an intelligent control subsystem. Technical obstacles of human excrement excretion environment, disease transmission, solid and liquid dirt damaging body health, rapid sterilization and incineration treatment of excrement, and sewage treatment and reuse are overcome; a full physical and chemical technology is adopted, excrement collection, microwave incineration, photocatalytic degradation, ultraviolet sterilization, a reclaimed water toilet flushing technology and an intelligent control system are integrated, rapid harmless treatment of human excrement is achieved, the traceless, colorless, odorless and secondary-pollution-free clean emission requirements are met, the convention that a sewer needs to be arranged in a toilet is broken, and all pollutant emission technical indexes meet the requirements specified by the national standard.

The invention belongs to the technical field of agro-product processing, and relates to a process for aging a meat duck after butchering. The process is characterized in that the butchered and cleanedmeat duck is subjected to acid discharge after precooling and spray preservation, wherein the acid discharge is carried out by two stages: the first stage is at a temperature of between 5 and 8 DEG Cand humidity of between 70 and 75 percent for 2 to 3 hours; and the second stage is at a temperature of between 0 and 4 DEG C and humidity of between 85 and 90 percent in 13 to 14 hours. Experimentsprove that the method can obviously improve the tenderness, moisture retention, flavor and other comprehensive qualities of the killed meat duck, and can ensure and improve product safety through spray preservation. The process has short period and convenient operation, and can be applied to industrial production.

The invention discloses a long-term anti-freezing antibacterial coating for extracorporeal membrane oxygenation (ECMO) device and a preparation method of the long-term anti-freezing antibacterial coating. The method comprises the following steps: (1) mixing an anti-freezing functional monomer, an antibacterial functional monomer and a film formation agent, and performing a reaction in a mode of free radical polymerization for 10-15 hours at 60-80 DEG C so as to obtain an anti-freezing antibacterial polymer; and (2) mixing the anti-freezing antibacterial polymer with a solvent, so as to obtainthe long-term anti-freezing antibacterial coating. The invention designs the coating with long-term anti-freezing and antibacterial functions simultaneously, and antifouling and sterilization functions can be well combined. With the combination of two functions, an effect of reducing risks of bacterium infection for a long time can be achieved. By reasonably selecting and controlling introductionof antibacterial functional components, the anti-freezing function of the coating can be well maintained.

The invention relates to a glass explosion-proof film with antibacterial and antimildew effects, which includes a PET protective film from the outside to the inside, a UV light-cured coating, a PET pre-coated film, an anti-mildew resin installation adhesive layer and a PET release film, UV light The main raw materials of the cured coating and their mass parts are: 10-15 parts of antibacterial and anti-mildew oligomer resin, 25-28 parts of wear-resistant UV oligomer resin, 4-7 parts of trimethylolpropane triacrylate, light 1844-6 parts of initiator, 0.3-0.5 parts of wetting and leveling agent, 50 parts of ethyl acetate; the main raw materials and parts by mass of anti-mold resin installation adhesive layer are: 10-20 parts of PHMG‑PUA, 10 parts of butyl acrylate ~15 parts, 8~14 parts of isooctyl methacrylate, 5~10 parts of diacetone acrylamide, 3~5 parts of azobisisobutyronitrile, 50 parts of ethyl acetate. Compared with the traditional anti-explosion film, the anti-bacterial and mildew-proof effect is durable, and the effective rate of inhibiting and killing Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus reaches more than 96%. At the same time, the invention also provides a A method for preparing a glass explosion-proof film with antibacterial and antifungal effects.

The invention belongs to the field of fish disease prevention and control, and in particular relates to a coating for preventing irritating Cryptocaryoniasis and a preparation method thereof. The coating for preventing and stimulating Cryptocaryoniasis provided by the invention consists of 3-5 parts of copper powder, 30-40 parts of Portland cement, 35-45 parts of quartz sand, 0.4-0.6 parts of anhydrous citric acid, and cement-based osmotic crystallization masterbatch. It consists of 7-8 parts, and its preparation method includes two steps of weighing and stirring. The coating for preventing Cryptocaryon irritanosis provided by the invention is applied on the bottom of the pool, which can make the cysts of Cryptocaryon irritans lose their splitting activity and die, prevent their reproduction and secondary infection, and its formula composition is safe and non-toxic, and has no effect on fish. Any adverse effects will not cause seawater pollution. In addition, the preparation method of the paint for preventing Cryptocaryon irritanosis provided by the invention is simple, easy to use, has remarkable effect of repelling and killing Cryptocaryon irritant, and is easy to realize large-area application.
