摘要：【中文】一种以氧化锌为材料制备高稳定性耐腐蚀超双疏材料的方法，将氧化锌颗粒加入到氨水与无水乙醇的溶液中，超声分散，然后搅拌均匀，得到混合液；向混合液中，加入正硅酸乙酯和全氟癸基三乙氧基硅烷，搅拌均匀，得到悬浊液，过滤干燥，得到超双疏颗粒；将超双疏颗粒加入到含有聚四氟乙烯与聚乙烯吡咯烷酮的乙醇溶液中，超声分散，搅拌均匀，均匀涂覆于基底上，干燥。本发明通过简单的操作步骤，温和的反应条件便可得到高稳定性的超双疏材料，且该超双疏材料不仅具有不受基底限制的优点，而且还具有耐腐蚀性能。因此，我们本发明制备的高稳定性耐腐蚀、高稳定性超双疏材料无论是学术研究还是工业应用方面，都具有优异的应用前景。 【EN】A method for preparing a high-stability corrosion-resistant super-amphiphobic material by taking zinc oxide as a material comprises the steps of adding zinc oxide particles into a solution of ammonia water and absolute ethyl alcohol, carrying out ultrasonic dispersion, and then uniformly stirring to obtain a mixed solution; adding tetraethoxysilane and perfluorodecyl triethoxysilane into the mixed solution, uniformly stirring to obtain a suspension, filtering and drying to obtain super-amphiphobic particles; adding the super-amphiphobic particles into an ethanol solution containing polytetrafluoroethylene and polyvinylpyrrolidone, ultrasonically dispersing, uniformly stirring, uniformly coating on a substrate, and drying. The invention can obtain the super-amphiphobic material with high stability through simple operation steps and mild reaction conditions, and the super-amphiphobic material not only has the advantage of no limitation of a substrate, but also has corrosion resistance. Therefore, the super-amphiphobic material with high stability, corrosion resistance and stability, which is prepared by the method disclosed by the invention, has excellent application prospects in both academic research and industrial application.

摘要：【中文】本发明公开了一种正压医用防护口罩，具有口罩面体和拉紧带，口罩面体具有面体内层和面体外层，所述的口罩面体上装有正压力气体传输组件，该正压力气体传输组件包括进气软管和与进气软管相连的进气接头，进气接头装于所述的口罩面体上，正压力气体可由进气软管经进气接头进入到口罩面体的面体内层内侧。本发明的正压医用防护口罩可以较好地阻止外部环境空气中的微粒，飞沫、毒菌等有害物的吸入，过滤效果好，并能加速面体内层内侧呼出气体的快速排出，水蒸气存留少，佩戴舒适。 【EN】The invention discloses a positive pressure medical protective mask which is provided with a mask body and a tensioning belt, wherein the mask body is provided with a mask inner layer and a mask outer layer, a positive pressure gas transmission assembly is arranged on the mask body and comprises a gas inlet hose and a gas inlet connector connected with the gas inlet hose, the gas inlet connector is arranged on the mask body, and positive pressure gas can enter the inner side of the mask body inner layer through the gas inlet hose and the gas inlet connector. The positive pressure medical protective mask can better prevent the inhalation of harmful substances such as particles, spray, poisonous bacteria and the like in the air of the external environment, has good filtering effect, can accelerate the rapid discharge of the exhaled air at the inner side of the inner layer of the mask body, has little water vapor retention and is comfortable to wear.
