Disinfection sterilizing type medical supersonic couplant and method of preparing the same

The invention discloses a disinfection sterilization medical ultrasonic coupling medium with the bactericidal function and used in the ultrasonic detection and treatment of skin and cavitary mucosa and a preparation method of the coupling medium, wherein, the ultrasonic coupling medium comprises propylene glycol, de-ionized water and one viscosity modifier of the hydroxy ethyl cellulose, carbomer and hydroxy propyl cellulose. The coupling medium further comprises a fungicide of 0.05 to 0.15 percent and the constituents of the fungicide are any one of polyhexamethylene biguanide, benzalkonium chloride, benzalkonium bromide, chlorhexidine acetate, trichlorobenzene phenoxy diphenyl ether and nanometer silver or any combination of the olyhexamethylene biguanide, the benzalkonium chloride, the benzalkonium bromide, the chlorhexidine acetate, the trichlorobenzene phenoxy diphenyl etherand, and the nanometer silver; the preparation method used for preparing the ultrasonic coupling medium is as follows: dispersing the hydroxy ethyl cellulose in the propylene glycol, stirring and dispersing the hydroxy ethyl cellulose by adding enough water, heating to 75 to 80 DEG C, preserving the heat for 30 minutes to cool the hydroxy ethyl cellulose and the propylene glycol to 45 DEG C, adding the fungicide to stir and cool the fungicide, the hydroxy ethyl cellulose and the propylene glycol to obtain the filled coupling medium. Tests show that the products of the coupling medium have fast and long sterilization effect and meet the requirements of various related standards.

Fruit-vegetables antistaling agent with browning resistant and sterilizing effect

The invention discloses a fruit and vegetable fresh-keeping agent capable of antibrowning and sterilizing, which is characterized in that the fresh-keeping agent belongs to an oxidized form disinfectant of efficiency, safety and non-toxicity with obvious antibrowning effect. The fresh-keeping agent contains one out of four disinfectants including sodium chlorite, chlorinedioxide, hydrogen peroxide and ozone. The application ranges of the solution concentration are respectively: the sodium chlorite 100-500mg / L, the chlorinedioxide 100-500mg / L, the hydrogen peroxide 0.5-5 per cent and the ozone 0.5-5mg / L. Compared with the conventional antibrowning agent, the majority of the agents are reducing agents or chelating agents, such as ascorbic acid and the salts thereof or citric acid, etc., and have no sterilization effect or obvious bacteriostatic effect, although part of the agents has the sterilization effect, such as sulfocompounds of sulfurous acid and the salts thereof, etc., which are prohibited from applying to the fresh fruits and vegetables. The fruit and vegetable fresh-keeping agent disclosed by the invention is capable of antibrowning and sterilizing at the same time, and is applicable to the fresh fruits and vegetables as well as fresh-cut products thereof, so as to be the fresh-keeping agent of environmental friendliness and safety.

Bactericide composition containing pyraclostrobin and copper rosinate

The invention relates to a bactericide composition containing pyraclostrobin and copper rosinate, containing pyraclostrobin and copper rosinate as effective components, wherein, the weight ratio of pyraclostrobin to copper rosinate is 1:2-3. The bactericide composition provided by the invention is characterized by that: 1, the composition has good synergism on a plurality of crop diseases within the range of certain proportion; 2, drug resistance caused by using pyraclostrobin or copper rosinate alone can be delayed greatly because pyraclostrobin and copper rosinate have different mechanisms of action and no cross-resistance between each other; and 3, pyraclostrobin is a novel bactericide with high price, while copper rosinate is cheaper, so that the combination of pyraclostrobin and copper rosinate can reduce the cost. The bactericide composition is a novel bactericide with high efficiency, low toxicity and broad-spectrum, with the advantages of long persistent period and being easy to use. Because the bactericide composition has a large number of reaction sites, the bactericide composition does not easily to generate drug resistance. Furthermore, the bactericide composition has dual functions of preventing and treating, and is capable of treating common plant diseases caused by a plurality of fungi and bacteria, such as downy mildew, epidemic disease, black spot disease, anthracnose, bacterial angular leaf spot, blight, tomato late blight of melons and fruits and the like.

Hollow silicon dioxide microsphere with pores in graded distribution as well as preparation method and application thereof

The invention discloses a hollow SiO2 (silicon dioxide) microsphere with pores in graded distribution as well as a preparation method and an application thereof. The preparation method comprises the steps that: polrvinyl benzene microspheres, ethyl orthosilicate, ammonia water, ethanol, water and alkyl ammonium bromide are used as raw materials, a sol-gel method is adopted for preparing the hollow SiO2 microsphere, during the preparation, the polrvinyl benzene microspheres are used as a hollow template, the alkyl ammonium bromide is used as pore formers, two to three layers of SiO2 cases are covered on the polrvinyl benzene microspheres to form composite microspheres, the carbon numbers of the pore formers used during the covering of each layer of SiO2 cases are different, and the hollow SiO2 microsphere with pores in graded distribution is finally obtained through calcination. The use performance of the hollow SiO2 microsphere is optimized, the hollow SiO2 microsphere with different case layer thicknesses, specific surface area, pore volume and apertures, and the pores of the hollow SiO2 microsphere are distributed in a gradually increased way from outside to inside in the radialdirection of a case layer. The microsphere obtained by the method has the advantages that the adsorption speed is accelerated, the adsorption quantity is increased, and good application is realized in the aspects of aquatic dye molecule adsorption and food preservative load.
