Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a rapid detection device for the diffusion and permeability of emulsions. Background Art

[0002] In the process of research and development, emulsions are often used as a medium. In actual work, it is necessary to test and compare the diffusion and permeability indicators of emulsions.

[0003] In addition, existing research mainly focuses on the detection of the permeability of emulsions, and basically does not involve the detection of the diffusion of emulsions in the subjects.

[0004] The existing technology for testing the permeability of emulsifiable concentrates is to first culture, then extract, and finally use gas chromatography for testing. This method has high accuracy, but is time-consuming, expensive, requires professional equipment, professional personnel, and professional data processing, and is not suitable for non-professionals.

[0005] The patent with publication number "CN108918381A" "A method for rapidly and simultaneously determining the water diffusivity and moisture permeability of biomass materials" designs a method for determining the water diffusivity and moisture permeability of biomass materials, but this method is not suitable for the detection of the diffusivity and permeability of emulsifiable concentrates.

[0006] The article "Wang Yi, Zhang Lita, Zheng Feineng, et al. Effects of adjuvants on the permeability of cypermethrin in the cuticle of armyworms [J]. Acta Entomologica Sinica, 2000, (S1): 51-56." and the article "Wang Yi, Zhang Lita, Zheng Feineng, et al. Effects of adjuvants on the permeability of cypermethrin in the cuticle of cabbage leaves [J]. Chinese Agricultural Science, 2002,

[0007] (01):33-37. ", which provides a method for testing the permeability of emulsions, but does not test the diffusivity of emulsions at the same time. It takes several days, is expensive, requires professional equipment, professional personnel, and professional data processing, and is not suitable for non-professionals. The national standard "GBT 5550-2016 Determination of the dispersibility of surfactants" provides a method for determining the dispersibility of surfactants, which can be used as a reference method for testing the diffusivity of emulsions. However, this method requires special reagents and involves some hazardous chemicals, which is not friendly to operators and the environment.

[0008] The existing technology for testing the permeability of emulsions is more suitable for accurate testing of the permeability of a single emulsion sample. It cannot immediately conduct intuitive comparison of multiple samples and is not suitable for market promotion.

[0009] It can be seen that the existing detection and comparison methods of the diffusion and permeability indicators of emulsifiable concentrates have the following shortcomings: (1) There is no professional equipment and method in the existing technology that can simultaneously detect the diffusion and permeability indicators of emulsifiable concentrates; (2) The existing technology cannot directly and quickly compare the diffusion and permeability of multiple emulsifiable concentrates at the same time; (3) The existing detection methods take several days, are expensive, require special reagents, professional equipment, professional talents, and professional data processing, and are not suitable for large-scale promotion and application; (4) The results of the detection by the existing detection methods are mostly explained in terms of actual data, which is not intuitive. Utility Model Content

[0014] Each concentric circle includes a second preset number of circles with the same center and different radii, and a preset spacing is provided between each adjacent circle on the same concentric circle.

[0015] Working process and principle of the device: When using the device, first drop the emulsion whose permeability or diffusivity needs to be measured on the center of the concentric circles on the permeation and diffusion layer. After a certain period of time, observe the number of circles of the emulsion diffused in the concentric circles, and judge the diffusivity of the emulsion by the number of circles; observe the number of layers penetrated by the emulsion, and judge the permeability of the emulsion according to the number of layers;

[0016] When it is necessary to compare the diffusibility and permeability of two or more emulsions, different emulsions are dropped simultaneously in the centers of different concentric circles. After the same period of time, the number of circles diffused by the emulsions can be compared to determine the diffusibility of the emulsions; the number of layers penetrated by the emulsions can be compared to determine the permeability of the emulsions.

[0017] When using the device, the penetration and diffusion of the emulsion oil on the permeation and diffusion layer is observed, and the permeability and diffusivity of the emulsion oil are judged by the number of layers that have been penetrated and diffused, so that the diffusivity and permeability of the emulsion oil can be obtained intuitively, quickly and simply. The problem that the existing method for detecting the permeability of emulsion oil is complicated and costly, and the existing technology lacks a device for quickly detecting and comparing the diffusivity of emulsion oil is solved.

[0018] Furthermore, the preset number of layers is 10 to 20 layers.

[0045] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0047] See also Figures 1 to 3 The first embodiment of the utility model provides a rapid detection device for the diffusion and permeability of emulsifiable concentrate, the device comprising a hollow shell 1, the shell 1 comprising, from bottom to top, an impermeable layer 3 for blocking the penetration of emulsifiable concentrate and a permeable diffusion layer 2 arranged on the upper part of the impermeable layer 3;

[0048] Please refer to Figure 1 and Figure 3 , the permeation diffusion layer 2 includes a preset number of layers of rapid qualitative filter paper or printing paper with the glossy surface facing upward, and a first preset number of concentric circles are evenly arranged on each filter paper or printing paper;

[0049] Each concentric circle includes a second preset number of circles with the same center and different radii, and a preset spacing is provided between each adjacent circle on the same concentric circle.

[0050] Working process and principle of the device: When using the device, first drop the emulsion whose permeability or diffusivity needs to be measured on the center of the concentric circles on the permeation diffusion layer 2. After a certain period of time, observe the number of circles of the emulsion diffused in the concentric circles, and judge the diffusivity of the emulsion by the number of circles; observe the number of layers penetrated by the emulsion, and judge the permeability of the emulsion according to the number of layers;

[0051] When it is necessary to compare the diffusibility and permeability of two or more emulsions, different emulsions are dropped simultaneously in the centers of different concentric circles. After the same period of time, the number of circles diffused by the emulsions can be compared to determine the diffusibility of the emulsions; the number of layers penetrated by the emulsions can be compared to determine the permeability of the emulsions.

[0052] It should be noted that when different emulsifiable concentrates are dropped on different concentric circles at the same time, the time points of dropping the different emulsifiable concentrates and the distances from the test paper are preferably the same.

[0053] For example, when using this device, 0.1 mL of emulsion is added at a distance of 10 cm from the test paper, and the paper is allowed to stand for 2 minutes. The number of penetrated pages is counted to determine the permeability of the emulsion, and the number of penetrated rings on each page is counted to determine its diffusivity.

[0054] When using the device, the penetration and diffusion of the emulsifiable concentrate on the permeation and diffusion layer 2 are observed, and the permeability and diffusivity of the emulsifiable concentrate are judged by the number of layers that have been penetrated and diffused, so that the diffusivity and permeability of the emulsifiable concentrate can be obtained intuitively, quickly and simply. The problem that the existing method for detecting the permeability of emulsifiable concentrate is complicated and costly, and the existing technology lacks a device for quickly detecting and comparing the diffusivity of emulsifiable concentrate is solved.

[0055] The permeability and diffusivity of emulsions can be observed intuitively and simultaneously, and the permeability and diffusivity of emulsions can be preliminarily judged. The permeability and diffusivity of three different emulsions can be compared intuitively at the same time. The materials used in the device are easy to obtain, the price is cheap, the operation method is simple, it can be reused, the observation results are intuitive and clear, and it is suitable for non-professionals to display and compare, and suitable for large-scale promotion and use.

[0056] In some embodiments of the present invention, the preset number of layers is 10 to 20. Preferably, the preset number of layers of the rapid qualitative filter paper or the printing paper with the glossy side facing upward is 15.

[0057] The multi-page permeation diffusion layer 2 is made of easily available rapid qualitative filter paper or ordinary A4 paper with the glossy side facing upwards. After use, the multi-page permeation diffusion layer 2 can be taken out and replaced with a new one, and can be reused.

[0058] In some embodiments of the present invention, the preset spacing is 0.1-0.8 cm. Preferably, the preset spacing is 0.5 cm.

[0059] In some embodiments of the present invention, the first preset number is 2 to 4 concentric circles. Preferably, the first preset number is 3 concentric circles.

[0060] In some embodiments of the present invention, the second preset number is 2 to 10. Preferably, the second preset number is 4 circles.

[0061] In some embodiments of the present invention, the material of the anti-seepage layer 3 is plastic or rubber. It is understandable that the anti-seepage layer 3 can prevent the penetration of emulsion.

[0062] Please refer to Figure 2 and Figure 5 In some embodiments of the present invention, a flip-up protective cover 4 is also provided on the permeation diffusion layer 2 .

[0063] In some embodiments of the present invention, please refer to Figure 5 The protective cover 4 is provided with a diffusion and permeability marking scale for evaluating the diffusion and permeability of the emulsifiable concentrate.

[0064] For example, in some embodiments, the identification scale is: the permeability reference standard is: after many tests, the methylated vegetable oil generally has 4-8 penetration layers, and the silicone additive has more than 8 penetration layers. Therefore, we define the number of penetration layers less than or equal to 4 as weak permeability, the number of penetration layers greater than 4 and less than or equal to 8 as medium permeability, and greater than 8 as strong permeability.

[0065] In the above structure, the diffusion reference standard is: if the diffusion position of the first layer is smaller than the second layer circle, it is weak diffusion; if the diffusion position is larger than the second layer circle, it is medium diffusion; and if the diffusion position is larger than the third layer circle, it is strong diffusion.

[0066] In some embodiments of the present invention, please refer to Figure 5 , Figure 8 and Fig. 9 The device is provided with an automatic reading component. The automatic reading component includes a first detection element 7 arranged at the bottom of the protective cover 4, a data collection module 9 connected to the first detection element 7, and a display screen 10 arranged at the top of the protective cover 4. The display screen 10 is used to display the diffusion data collected by the data collection module 9.

[0067] It can be understood that when the device is used to detect the diffusibility of emulsifiable concentrate, the emulsifiable concentrate whose diffusibility needs to be measured is first dropped on the center of the concentric circles on the permeable diffusion layer 2. After a certain period of time, the first detection element 7 can automatically measure the number of circles of the emulsifiable concentrate diffusion in the concentric circles, and transmit the data of the number of circles to the data collection module 9, which then transmits the information to the display screen 10, so that the diffusibility of the emulsifiable concentrate can be intuitively determined. The first detection element 7, the data collection module 9, and the display screen 10 are commercially available components and assemblies.

[0068] It can be understood that by arranging the first detection element 7 at the bottom of the protective cover 4, arranging the data collection module 9 connected to the first detection element 7, and electrically connecting the data collection module 9 to the display screen 10, the first detection element 7 automatically detects the number of diffusion circles of the emulsifiable concentrate, thereby realizing rapid and automatic detection of the diffusivity of the emulsifiable concentrate, making the device more intelligent, and solving the problems that the existing methods for detecting the permeability of emulsifiable concentrate are complicated and costly, and there is a lack of a device for detecting the diffusivity of the emulsifiable concentrate in the prior art.

[0069] When it is necessary to compare the diffusibility of two or more emulsifiable concentrates, different emulsifiable concentrates are dropped at the centers of different concentric circles at the same time. After the same time, the first detection element 7 will still collect information respectively, transmit it to the data collection module 9, and then transmit the information to the display screen 10. According to the data of the display screen 10, the diffusibility of two or more emulsifiable concentrates can be conveniently judged. The device can quickly judge the diffusibility of emulsifiable concentrates, which is convenient and fast and has advantages. The existing method for detecting the diffusibility of emulsifiable concentrates is complex and costly, so that the operation is complicated and the cost is high when comparing the diffusibility of two or more emulsifiable concentrates.

[0070] In some embodiments of the present invention, please refer to Figure 6 and Figure 7A storage box 8 is connected to the bottom of the housing 1, which can be used to place straws, replace filter paper and other items. The storage box 8 is provided to achieve the integration of the device, the structure is simple, and the device is more convenient.

[0071] The storage box 8 can be connected to the bottom of the housing 1 by a detachable connection method such as a magnetic connection or an adhesive connection that is easy to disassemble and fix, or it can be fixedly connected to the housing 1 in an integral manner.

[0072] In some embodiments of the present invention, please refer to Figure 2 The housing 1 is provided with a fixing member 5 movably connected to the protective cover 4 , and one end of the fixing member 5 is fixedly connected to the housing 1 .

[0073] In some embodiments of the present invention, please refer to Figure 2 The fixing member 5 is a magnetic buckle, one end of which is fixedly connected to the housing 1, and the other end of which is movably connected to the protective cover 4 to realize the opening and closing of the protective cover 4.

[0074] It is understandable that the provision of the magnetic buckle and the protective cover 4 can better protect the impermeable layer 3 and the permeable diffusion layer 2 inside the housing 1, avoid the failure of the filter paper or the printing paper, and ensure accurate results.

Therefore, we define the number of penetration layers less than or equal to 4 as weak permeability, the number of penetration layers greater than 4 and less than or equal to 8 as medium permeability, and greater than 8 as strong permeability.

[0086] In the above detection device, the diffusion reference standard is: if the diffusion position of the first layer penetrated is smaller than the second layer circle, it is weak diffusion; if the diffusion position is larger than the second layer circle, it is medium diffusion; and if the diffusion position is larger than the third layer circle, it is strong diffusion.
