[0002] Ceramic silicone foam is a high-performance composite material combining the properties of ceramic fibers and silicone. It typically possesses characteristics such as high-temperature resistance, thermal insulation, fire resistance, flexibility, and sealing. It is mainly used in industrial, automotive, aerospace, electronics, and building fire protection sectors. During the production of ceramic silicone foam, product thermal insulation testing is required. Currently, this is primarily done by sending samples to testing institutions, but the testing cycle generally takes about 7 working days, resulting in low testing efficiency and high testing costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that the existing main method of sending samples to testing institutions for testing generally takes about 7 working days, resulting in low testing efficiency and high testing costs, a ceramic silicone foam thermal insulation testing device is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a ceramic silicone foam thermal insulation testing device, including a testing platform, a heating device and a temperature detection device, wherein the heating device has a heating end for heating the ceramic silicone foam, and the temperature detection device is provided with a first detection end and a second detection end.

[0005] The system also includes a clamping mechanism comprising a clamping block. The heating end of the heating device is placed on the upper surface of the test platform, and the clamping block is positioned above and opposite the heating end of the heating device. The space between the clamping block and the heating end of the heating device is used to clamp the ceramic silica foam under test. A first detection end is located on the side of the ceramic silica foam located at the heating end of the heating device, and a second detection end is located on the side of the ceramic silica foam located at the clamping block. The test platform is equipped with a drive mechanism for controlling the clamping block to move closer to or away from the heating end of the heating device. Compared to existing technologies, this solution uses a drive mechanism to control the clamping block to move closer to or away from the heating end of the heating device, thereby clamping or releasing the ceramic silica foam between the clamping block and the heating end of the heating device. This allows for rapid testing of the thermal insulation performance of the ceramic silica foam, improving testing efficiency. Furthermore, the simple structure of the test device reduces testing costs.

[0006] To facilitate the control of the displacement of the clamping block by the drive mechanism, in some preferred embodiments, an outer frame is fixed on the upper surface of the test platform, the clamping block is slidably mounted on the outer frame, the drive mechanism is mounted on the outer frame, and the drive mechanism is located above the clamping block.

[0007] In order to enable the clamping block to slide on the outer frame, in some preferred embodiments, a guide shaft is fixedly connected to the clamping block, the guide shaft is set along the height direction of the test platform, and a guide sleeve is fixedly connected to the outer frame, the guide sleeve is matched with the guide shaft, and the guide sleeve is sleeved on the guide shaft.

[0008] To implement the drive mechanism, in some preferred embodiments, the drive mechanism includes a worm gear lifting mechanism fixed on the outer frame, wherein the lifting end of the worm gear lifting mechanism is rotatably mounted on the end of the guide shaft away from the clamping block.

[0009] To facilitate understanding of the clamping force on the ceramic silicone foam, in some preferred embodiments, a pressure sensor is provided between the clamping block and the drive mechanism.

[0010] To facilitate control of the clamping force on the ceramic silicone foam, in some preferred embodiments, the test platform is equipped with a displacement sensor, which is used to control the displacement range of the drive mechanism and control the pressure of the clamping block on the tested ceramic silicone foam.

[0011] In some preferred embodiments, the clamping block is made of aluminum.

[0012] In some preferred embodiments, both the first detection end and the second detection end are provided in twos.

[0013] The beneficial effects of this utility model are as follows: When using the ceramic silica foam thermal insulation testing device of this utility model, the driving mechanism controls the clamping block to move closer to or further away from the heating end of the heating device, thereby pressing or releasing the ceramic silica foam between the clamping block and the heating end of the heating device. This enables rapid testing of the thermal insulation performance of the ceramic silica foam, improving testing efficiency. At the same time, the simple structure of the testing device also reduces testing costs, avoiding the problems of low testing efficiency and high testing costs associated with the existing method of sending the foam to a testing institution for testing, which typically takes about 7 working days.

[0022] like Figure 1-2As shown, a ceramic silica foam thermal insulation testing device includes a testing platform 1, a heating device 2, a temperature detection device 3, and a pressing mechanism. The heating device 2 has a heating end 4 for heating the ceramic silica foam 8. The temperature detection device 3 is provided with a first detection end 5 and a second detection end 6. In this embodiment, the manufacturer of the heating device 1 is Xiamen Dedian Co., Ltd., and its model is D7408. The heating end 4 is a silicon carbide rod. The manufacturer of the temperature detection device 3 is Xiamen Dedian Co., Ltd., and its model is PT808. Its heating temperature can reach 1000 degrees Celsius with an accuracy of 1 degree Celsius.

[0023] The heating end 4 of the heating device 2 is placed on the upper surface of the test platform 1. The clamping block 7 is located above the heating end 4 of the heating device 2 and is positioned opposite to it. The space between the clamping block 7 and the heating end 4 of the heating device 2 is used to clamp the ceramic silicone foam 8 being tested. The first detection end 5 is located on one side of the ceramic silicone foam 8 located on the heating end 4 of the heating device 2. The second detection end 6 is located on one side of the ceramic silicone foam 8 located on the clamping block 7. The test platform 1 is provided with a drive mechanism 9 for controlling the clamping block 7 to move closer to or further away from the heating end 4 of the heating device 2. The clamping block 7 is made of aluminum.

[0024] An outer frame 10 is fixed to the upper surface of the test platform 1. A guide shaft 11 is fixedly connected to the clamping block 7. The guide shaft 11 is set along the height direction of the test platform 1. A guide sleeve 12 is fixedly connected to the outer frame 10. The guide sleeve 12 matches the guide shaft 11. The guide sleeve 12 is sleeved on the guide shaft 11 to realize that the clamping block 7 is slidably installed on the outer frame 10. The drive mechanism 9 is installed on the outer frame 10. The drive mechanism 9 is located above the clamping block 7. The drive mechanism 9 includes a worm gear lifting mechanism fixed on the outer frame 10. The lifting end of the worm gear lifting mechanism is rotatably installed on the end of the guide shaft 11 away from the clamping block 7.

[0025] A pressure sensor 13 is installed between the clamping block 7 and the drive mechanism 9, and a displacement sensor 14 is installed on the test platform 1. The displacement sensor 14 is used to control the displacement range of the drive mechanism 9 and control the pressure of the clamping block 7 on the tested ceramic silicone foam 8. Two sensors are installed on both the first detection end 5 and the second detection end 6. The pressure sensor 13 is an S-type pressure sensor with a pressure range of 0-50KN, and the displacement sensor 14 is a WYD high-precision displacement sensor. At the same time, the test thickness range between the clamping block 7 and the heating end 4 of this test device is 0-50MM.

[0026] Before testing, the above-mentioned ceramic silicone foam insulation testing device first attaches the first detection end 5 of the temperature detection device 3 to the lower surface of the ceramic silicone foam 8 with tape, and then attaches the second detection end 6 of the temperature detection device 3 to the upper surface of the ceramic silicone foam 8 with tape. The ceramic silicone foam 8 is then placed between the pressing block 7 and the heating end 4 of the heating device 2. By controlling the rotation of the power input end of the worm gear lifting mechanism of the drive mechanism 9, the lifting end of the worm gear lifting mechanism drives the guide shaft 11 to slide within the guide sleeve 12, thereby causing the pressing block 7 to slide down and press the ceramic silicone foam 8. At this time, the first detection end 5 of the heating device 2 is located between the ceramic silicone foam 8 and the heating end 4 of the heating device 2, and the second detection end 6 of the heating device 2 is located between the ceramic silicone foam 8 and the pressing block 7, thus completing the pressing of the ceramic silicone foam 8.

[0027] During testing, the heating temperature of the heating device 2 is set to 500℃, and the pressure of the pressure sensor 13 is set to 0.4 MPa. This means measuring the temperature of the heating surface and the insulation surface of the ceramic silicone foam 8. The temperature detected by the first detection end 5 of the heating device 2 is reduced by the temperature of the second detection end 6, and the difference is the insulation temperature.
