Description

Technical Field

[0001] This utility model relates to the field of high-temperature peroxide vulcanizate technology, and in particular to a comprehensive testing device for polymer materials. Background Technology

[0002] Oxide vulcanization refers to the phenomenon of adding organic peroxides (such as diisopropylbenzene peroxide) to rubber compounds, which release free radicals during vulcanization heating. It promotes the formation of carbon-carbon bonds between rubber polymer chains through peroxides, belonging to a non-sulfur vulcanization system. In the production of high-temperature resistant peroxide vulcanizates, comprehensive testing of the peroxide vulcanizates is required using testing equipment.

[0003] As shown in the reference case "A polymer material density testing device" announcement number "CN213121498U", the polymer material is clamped by a clamping block and moved on both sides by a motor. The density of the polymer material in vacuum environment, air environment and water environment is measured by a vacuum detection box, a measuring instrument and a water block respectively. There is no need to change the instrument. The density of the material under different environments can be tested at the same time, which is very convenient and highly practical.

[0004] According to the aforementioned reference materials, in the above-mentioned device, motor two drives the double-threaded screw to rotate, causing the sliding covers to move towards each other, closing the top of the vacuum detection box, starting the vacuum pump to evacuate the box into a vacuum, and recording the data at this time; then, the slider is controlled to move to the top of the measuring instrument at the other end, and the telescopic cylinder places the material on the top of the measuring instrument at the other end for measurement and counting; finally, the telescopic cylinder is moved to the middle, and the telescopic cylinder places the material into the water-filled block for measurement and counting. However, when conducting comprehensive testing on peroxide-cured perfluoroether rubber, the testing device is not ideal in testing the high and low temperature resistance, aging resistance, and chemical corrosion resistance of peroxide-cured perfluoroether rubber, making it inconvenient to effectively test peroxide-cured perfluoroether rubber and reducing the effectiveness of the testing equipment. Utility Model Content

[0005] Therefore, it is necessary to provide a comprehensive testing device for polymer materials to address the problem of inconvenience in effectively testing perfluoroether rubber vulcanized by peroxide.

[0006] The device includes an outer casing, with a lid installed at one end of the top of the casing. A placement box is provided on the top of the inner wall of the casing, and a testing mechanism is provided on the inner wall of the casing. The testing mechanism includes heating rods installed on both sides of the inner wall of the casing. Baffles are slidably connected to both sides of the inner wall of the casing. The baffles are located on one side of the heating rods. Two electric push rods are fixed at the bottom of the baffles. The electric push rods are installed on the inner wall of the casing. An acid-resistant component is provided on the inner wall of the casing.

[0007] In one embodiment, the testing mechanism further includes a temperature-conducting plate fixedly connected to the bottom of the inner wall of the placement box, and two semiconductor cooling chips are installed on both sides of the inner wall of the outer shell, with one end of the semiconductor cooling chip attached to both sides of the bottom of the temperature-conducting plate.

[0008] In one embodiment, heat sinks are mounted at both ends of the semiconductor cooling chip.

[0009] In one embodiment, a cooling fan is mounted on the other end of the heat sink.

[0010] In one embodiment, a display is mounted on the front end of the lid, and an infrared temperature sensor is mounted on the rear end of the lid, with one end of the infrared temperature sensor connected to the display.

[0011] In one embodiment, the acid-resistant component includes several atomizing nozzles evenly arranged and installed on the top wall of the placement box, with one end of each atomizing nozzle connected to a water guide pipe.

[0012] In one embodiment, a water storage tank is installed at the top of the outer casing, and a water pump is connected to the front end of the water storage tank.

[0013] In one embodiment, the top of one end of the water pump is connected to one end of the water pipe. Beneficial effects

[0014] 1. The aforementioned comprehensive polymer material testing equipment features two heating rods on both sides of the outer shell. When energized, these rods raise the temperature inside the chamber, enabling high-temperature testing of peroxide-cured perfluoroether rubber. During low-temperature testing, two electric push rods move baffles upwards to shield and isolate the heating rods, preventing damage from low temperatures and salt spray. The cold ends of multiple semiconductor cooling chips contact a temperature-conducting plate, allowing the plate to conduct cold air for low-temperature testing of the peroxide-cured perfluoroether rubber inside the chamber. A heat sink absorbs and conducts heat from the hot ends of the semiconductor cooling chips, and a cooling fan dissipates heat between the heat sink and the hot ends of the semiconductor cooling chips. The chamber is made of Alloy926 alloy plate, which has excellent conductivity and corrosion resistance, improving the testing effect of the equipment on peroxide-cured perfluoroether rubber. An infrared temperature sensor detects the temperature of the equipment, and the temperature is observed on a display screen. This allows for high and low temperature resistance testing of peroxide-cured perfluoroether rubber, enhancing the overall testing effectiveness of the equipment. 2. When conducting corrosion resistance tests on peroxide-cured perfluoroether rubber, a water pump can deliver the salt spray liquid in the storage tank to the water pipe. The water pipe sprays the salt spray through the atomizing nozzle. The atomizing nozzle is set at the top of the inner wall of the placement chamber, which can uniformly spray the peroxide-cured perfluoroether rubber, improve the corrosion resistance of the peroxide-cured perfluoroether rubber, and improve the finished product quality of peroxide-cured perfluoroether rubber.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5This invention describes a comprehensive testing device for polymer materials.

[0020] In one embodiment, a comprehensive testing device for polymer materials includes a housing 100, a cover 200 installed at one end of the top of the housing 100, a placement box 300 provided at the top of the inner wall of the housing 100, and a testing mechanism 400 provided on the inner wall of the housing 100. The testing mechanism 400 includes heating rods 410 installed on both sides of the inner wall of the housing 100, baffles 420 slidably connected to both sides of the inner wall of the housing 100, the baffles 420 being disposed on one side of the heating rods 410, two electric push rods 430 fixed at the bottom of the baffles 420, the electric push rods 430 being installed on the inner wall of the housing 100, and an acid-resistant component 490 provided on the inner wall of the housing 100.

[0021] It should be noted that the "MAX-60" comprehensive testing equipment is manufactured by... 100mm outer casing: mostly made of SEEC salt-treated steel plate or high-temperature resistant PVC plastic plate, combined with stainless steel frame structure to ensure long-term stable operation of the equipment.

[0022] Inner liner material: SUS304 stainless steel, which is highly corrosion resistant and combined with flame retardant materials to enhance safety.

[0023] Heating and humidification: Built-in electric heater and humidification tank, temperature control is achieved by heating the water in the evaporation tank.

[0024] Spray system: Uses non-crystallizing nozzles and pressure adjustment device to ensure uniform salt spraying.

[0025] Ventilation system: Built-in exhaust fan maintains a stable environment inside the enclosure.

[0026] When conducting comprehensive testing on peroxide-cured perfluoroelastomer rubber, the testing mechanism 400 heats the peroxide-cured perfluoroelastomer rubber via the heating rod 410 to perform heat resistance testing. The semiconductor cooling chip 450, in conjunction with the temperature conducting plate 440, can perform low-temperature resistance testing on the peroxide-cured perfluoroelastomer rubber. The acid-resistant component 490, via the water pump 494, delivers the salt spray liquid in the water pipe 492 to the atomizing nozzle 491 to perform corrosion resistance testing on the peroxide-cured perfluoroelastomer rubber. The combination of the testing mechanism 400 and the acid-resistant component 490 improves the testing of peroxide-cured perfluoroelastomer rubber without affecting the normal use of the testing equipment.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the testing mechanism 400 also includes a temperature-conducting plate 440 fixedly connected to the bottom of the inner wall of the placement box 300. Two semiconductor cooling chips 450 are installed on both sides of the inner wall of the outer shell 100. One end of the semiconductor cooling chip 450 is attached to both sides of the bottom of the temperature-conducting plate 440. Heat sinks 460 are installed at both ends of the semiconductor cooling chip 450. A cooling fan 470 is installed at the other end of the heat sink 460. A display 480 is installed at the front end of the box cover 200. An infrared temperature sensor 481 is installed at the rear end of the box cover 200. One end of the infrared temperature sensor 481 is connected to the display 480.

[0028] In this embodiment, the peroxide-cured perfluoroelastomer rubber can be heated by two heating rods 410 on both sides of the inner wall of the outer casing 100, increasing the temperature inside the placement box 300 and performing a high-temperature resistance test on the peroxide-cured perfluoroelastomer rubber. When performing a low-temperature resistance test on the peroxide-cured perfluoroelastomer rubber, two electric push rods 430 drive the baffle 420 to move upward to isolate the heating rods 410 and open the heat dissipation channel of the cooling fan 470. After the semiconductor cooling chip 450 is energized, one end is the cold end that dissipates cold air, and the other end is the hot end. The cold end of the semiconductor cooling chip 450 contacts the temperature conducting plate 440 to conduct cold air, performing a low-temperature resistance test on the peroxide-cured perfluoroelastomer rubber inside the placement box 300. The cooling fan 470 and the heat sink 460 cooperate to transfer the heat generated by the hot end of the semiconductor cooling chip 450 to the outside of the outer casing 100, which can perform high and low temperature resistance tests on the peroxide-cured perfluoroelastomer rubber and improve the effectiveness of the testing equipment.

[0029] like Figure 5 As shown, the acid-resistant component 490 includes several atomizing nozzles 491 evenly arranged and installed on the inner top wall of the placement box 300. One end of the atomizing nozzle 491 is connected to a water guide pipe 492. A water storage tank 493 is installed on the top of the outer shell 100. A water pump 494 is connected to the front end of the water storage tank 493. The top of one end of the water pump 494 is connected to one end of the water guide pipe 492.

[0030] In this embodiment, the water pump 494 delivers the salt spray liquid in the water storage tank 493 to the water guide pipe 492, and the water guide pipe 492 delivers the liquid to the atomizing nozzle 491. The multiple atomizing nozzles 491 spray salt spray downwards to conduct corrosion resistance tests on the peroxide-cured perfluoroether rubber in the placement box 300. The salt spray liquid in the outer shell 100 is delivered to the outside through the pipe at the rear end of the outer shell 100, which can effectively test the peroxide-cured perfluoroether rubber and improve the quality of the peroxide-cured perfluoroether rubber.

[0031] Working principle: Open the lid 200 and place the peroxide-cured perfluoroether rubber into the placement box 300. Manually operate the display 480 to power the heating rod 410 for heat resistance testing. During low-temperature testing, the display 480 drives one end of the electric push rod 430 to move the baffle 420 upwards, blocking and isolating the heating rod 410. Manually operating the display 480 also drives the thermoelectric cooler 450, causing one end of the cooler to generate cold air. The cold end of the conductor cooling chip 450 contacts the temperature-conducting plate 440 to perform low-temperature resistance testing on the peroxide-cured perfluoroether rubber in the placement box 300. The infrared temperature sensor 481 can detect the temperature inside the placement box 300 to improve the testing effect. When performing corrosion resistance testing on the peroxide-cured perfluoroether rubber, the manual operation display 480 drives the water pump 494 to cooperate with the water pipe 492 to deliver the salt spray liquid in the water storage tank 493 to the atomizing nozzle 491. The atomizing nozzle 491 sprays out salt spray to perform corrosion resistance testing on the peroxide-cured perfluoroether rubber.

[0032] It should be noted that the heating rod 410, electric push rod 430, semiconductor cooling chip 450, cooling fan 470, display 480, infrared temperature sensor 481, and water pump 494 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the heating rod 410, electric push rod 430, semiconductor cooling chip 450, cooling fan 470, display 480, infrared temperature sensor 481, and water pump 494 can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
