Description

Technical Field

[0001] The utility model relates to a device for preparing an emulsion of a pesticide mineral oil emulsion and measuring its surface tension, in particular to a device with self-controlled temperature and stirring functions, which can prepare an emulsion and measure its surface tension immediately. Background Art

[0002] Mineral oil emulsion is a petroleum-based mineral-source pesticide. Its main ingredients are refined mineral oil with a certain fraction and emulsifier. It is emulsified with water and then sprayed. The liquid can quickly break up the emulsion and form an oil film after wetting and spreading on the surface of insect bodies, egg shells, and mycelium, sealing the pores and causing them to suffocate and die. Because it has a physical killing effect, low toxicity, no resistance, broad-spectrum control, and is environmentally friendly, it is widely used in the integrated prevention and control of year-round diseases and insect pests of crops.

[0003] Emulsion surface tension is a key indicator for evaluating the performance of mineral oil emulsion products. The lower the emulsion's surface tension, the better the spreading and wetting effect, the stronger the oil film, and the better the performance. Current surface tension measurement devices require the emulsion to be prepared in advance before transferring it to the surface tension measurement device for measurement. Considering the rapid oil-water separation rate of mineral oil emulsions, especially under temperature fluctuations, the oil-water separation during the transfer process causes the emulsion's surface tension to continuously change. Therefore, conventional surface tension measurement devices are unable to accurately measure its surface tension.

[0004] Therefore, in order to address the problem of accuracy in measuring the surface tension of the above-mentioned mineral oil emulsions, the present application designs a device for measuring the surface tension of the pesticide mineral oil emulsion. The device has its own temperature control and stirring function, which can not only measure the mineral oil emulsion immediately after preparation to obtain more accurate measurement results, but also perform continuous measurement of the emulsion for studying the oil-water separation process of the mineral oil emulsion.

[0059] The workbench 2 includes a liquid storage mechanism and a heating and stirring mechanism. In this embodiment, the liquid storage mechanism is an emulsion container and is placed in the placement tank 5. The heating and stirring mechanism includes: a support column 4, a placement tank 5, a magnetic rod, a heating coil and a temperature electrode 7; the support column 4 is fixed on the lifting platform 3, the support column 4 is fixed on the lifting platform 3, the placement tank 5 is fixed on the support column 4, and the heating coil is arranged at the bottom of the groove of the placement tank 5.

The temperature electrode 7 is placed in the emulsion container in the placement tank 5 through a rigid wire and is used to measure the temperature of the solution in the liquid storage mechanism. During the measurement operation, the lower end of the temperature electrode 7 is immersed in the liquid in the emulsion container to measure the temperature;

[0060] The platinum plate 8 is hung on the hook of the tensile gauge 9, and the platinum plate is located directly above the emulsion container; the tensile gauge 9 is installed on the lower surface of the frame top plate;

[0061] The bottom plate of the frame is provided with a display screen 14, an operation panel 16, and a power switch 13;

[0062] The power switch 13 is used to control the power supply of the device;

[0065] One end of the curved glass 10 is connected to the side panel of the frame through a hinge.

[0066] Working principle:

[0067] Level the machine body 1 using the leveling foot 15 and the spirit level, turn on the power switch 13, and set the temperature, stirring rate, and time parameters of the device through the operation panel 16 and the display screen 14. Place an emulsion container filled with water and a standard magnetic particle in the placement tank 5, place the temperature electrode 7, and start adjusting the temperature through the heating coil and the placement tank 5 serving as a constant temperature chamber. After the water temperature in the container stabilizes to the set temperature, hang the connecting rod of the platinum plate on the hook of the dynamometer 9. After it stabilizes and does not shake, reset the dynamometer reading to zero through the operation panel 16. The operation panel 16 is used to control the magnetic rod to control the standard magnet to start stirring the liquid in the container, and the mineral oil emulsion taken according to the dilution ratio is added to the emulsion container. After the addition is completed, the timing is started and displayed on the display screen 14, and the curved glass 10 is closed. After the timing is over, the device automatically stops stirring. After the liquid surface stabilizes, the emulsion to be tested is prepared. The platinum plate is brought close to but not touching the liquid surface of the emulsion to be tested in the emulsion container by using the knob 6. The motor is controlled by the operation panel 16 to automatically rise the lifting platform 3 so that the platinum plate just contacts the liquid surface. At this time, the dynamometer reading will change due to the surface tension of the liquid surface, so the motor stops. The knob 6 is further used to adjust the depth of the platinum plate immersed in the emulsion to be tested. The surface tension of the emulsion to be tested is measured by using the operation panel 16. The reading is read on the display screen 14 to determine the surface tension of the pesticide mineral oil emulsion.

[0068] This device is equipped with a temperature-controlled, timed stirring workbench 2. By enabling immediate preparation and measurement, it effectively reduces the time between emulsification completion and surface tension measurement of the mineral oil emulsion, thereby reducing the occurrence of demulsification and enabling accurate measurement of the surface tension of the mineral oil emulsion. Furthermore, the device has a simple structure and is easy to operate.

[0069] Example 2:

[0070] A specific method for measuring the surface tension of a mineral oil emulsion C:

[0071] Level the machine body 1 using the leveling foot 15 and the spirit level, turn on the power switch 13, set the device temperature to 30°C, the stirring rate to 180 r / min, and the time parameter to 2 min through the operation panel 16 and the display screen 14, place an emulsion container containing 100 ml of deionized water and a standard magnetic particle in the placement tank 5, place the temperature electrode 7 and start heating through the heating coil. After the water temperature in the container stabilizes to 30°C, hang the connecting rod of the platinum plate on the hook of the dynamometer 9. After it stabilizes and does not shake, reset the dynamometer reading through the operation panel 16. The operation panel 16 is used to control the magnetic rod to control the standard magnet to start stirring the liquid in the container. 0.5 ml of mineral oil emulsion is added to the emulsion container. After the addition is completed, a 2-minute timer is started. The data is displayed on the display screen 14 and the curved glass 10 is closed. After the timer ends, the device automatically stops stirring. After the liquid surface stabilizes, the emulsion to be tested is prepared. The platinum plate is brought close to but does not touch the liquid surface of the emulsion to be tested in the emulsion container by turning the knob 6. The motor is controlled by the operation panel 16 to automatically raise the lifting platform 3 so that the platinum plate just contacts the liquid surface. At this time, the dynamometer reading changes due to the surface tension of the liquid, so the motor stops. The height of the lifting platform 3 is further adjusted by turning the knob 6 so that the platinum plate is immersed in the emulsion to be tested to a depth of 3 mm. The surface tension of the emulsion to be tested is measured by starting from the operation panel 16 and readings are taken on the display screen 14 to measure the surface tension of the mineral oil emulsion C.

[0072] Example 3:

[0073] Comparing the surface tension test results of the present invention and the existing surface tension meter, the surface tension of the same mineral oil emulsion C was measured;

[0074] The surface tension of standard hard water at 30°C is about 70mN / m, and the surface tension of mineral oil is between 28-32mN / m. The emulsion of mineral oil emulsion C is an oil-in-water emulsion. The surface tension of the emulsion of mineral oil emulsion C is between water and mineral oil. Over time, after the separation of oil and water in the emulsion, its surface tension gradually decreases until the oil and water are completely separated and the surface tension is close to that of mineral oil.

[0075] The surface tension of the same mineral oil emulsion was measured using the present invention and an existing conventional surface tension meter. This example uses the preparation and measurement process of Example 2. The results are shown in Table 1. The test results show that the test results of the present invention are closer to the true value and can be measured immediately after preparation. The results measured by the existing surface tension meter are more inclined to the surface tension after oil-water separation and cannot truly reflect the surface tension of the emulsion.

[0077]

[0078] Example 4:

[0079] This device can continuously measure the change of the surface tension of the mineral oil emulsion C over time, and measure the surface tension of the emulsion at a constant temperature multiple times, so as to study the demulsification process;

[0080] Level the machine body 1 using the leveling foot 15 and the spirit level, turn on the power switch 13, set the device temperature to 30°C, the stirring rate to 180 r / min, and the time parameter to 2 min through the operation panel 16 and the display screen 14, place an emulsion container containing 100 ml of deionized water and a standard magnetic particle in the placement tank 5, place the temperature electrode 7 and start heating through the heating coil. After the water temperature in the container stabilizes to 30°C, hang the connecting rod of the platinum plate on the hook of the dynamometer 9. After it stabilizes and does not shake, reset the dynamometer reading through the operation panel 16. The operation panel 16 is used to control the magnetic rod to control the standard magnet to start stirring the water in the container. 0.5 ml of mineral oil emulsion is added to the emulsion container. After the addition is completed, a 2-minute timer is started. The data is displayed on the display screen 14 and the curved glass 10 is closed. After the timer ends, the device automatically stops stirring. After the liquid surface stabilizes, the emulsion to be tested is prepared. The platinum plate is brought close to but not touching the liquid surface of the emulsion to be tested in the emulsion container by using the knob 6. The motor is controlled by the operation panel 16 to automatically rise the lifting platform 3 until the platinum plate just touches the liquid surface. At this time, the tensile gauge shows The number will change, so the motor stops. The height of the lifting platform 3 is further adjusted by knob 6 so that the platinum plate is immersed in the emulsion to be tested to a depth of 3 mm. The surface tension of the emulsion to be tested is measured through the operation panel 16. The reading is read on the display screen 14, and the surface tension of the emulsion C is measured. Under the same operation, the constant temperature is continued to be controlled at 30°C, and its surface tension is measured at 10 minutes, 30 minutes, 60 minutes, and 120 minutes respectively. The results are shown in Table 2. However, the existing device cannot maintain constant temperature conditions and cannot perform multiple consecutive tests.

After the water temperature in the container stabilizes to 30°C, hang the connecting rod of the platinum plate on the hook of the dynamometer 9, and after it stabilizes and does not shake, reset the dynamometer reading to zero through the operation panel 16. The magnetic rod and the standard magnet were controlled by the operation panel 16 to begin stirring the water in the container. 0.5 ml of mineral oil emulsion C was added to the emulsion container. After the addition was completed, a 2-minute timer was started, the data was displayed on the display screen 14, and the curved glass 10 was closed. After the timer expired, the device automatically stopped stirring. After the liquid surface stabilized, the emulsion to be tested was obtained. The platinum plate was brought close to, but not touching, the liquid surface of the emulsion to be tested in the emulsion container using the knob 6. The motor was controlled by the operation panel 16 to automatically raise the lifting platform 3 until the platinum plate just touched the liquid surface. At this time, the tensiometer reading changed, and the motor stopped. The height of the lifting platform 3 was further adjusted using the knob 6 to immerse the platinum plate in the emulsion to a depth of 3 mm.
