Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a device for testing the thermal insulation performance of a coating. Background Art

[0002] The thermal insulation performance of coatings refers to the ability of the coating formed on the surface to hinder or reflect heat transfer. Specifically, the thermal insulation performance of coatings can reduce the heat inside the building by lowering the surface temperature, thereby achieving the purpose of energy conservation and emission reduction. The evaluation indicators of thermal insulation performance of coatings include thermal conductivity, solar reflectivity, solar radiation absorptivity, etc. Among them, the smaller the thermal conductivity, the better the thermal insulation performance of the coating, the higher the solar reflectivity, the better the heat protection performance of the coating, and the smaller the solar radiation absorptivity, the better the thermal insulation performance of the coating. Some commonly used coatings with thermal insulation properties include ceramic particle coatings, polymer coatings, silicate coatings, etc. These coatings achieve thermal insulation effects through different mechanisms, such as reflection, scattering, absorption, etc.

[0003] The patent name is "CN219777547U", which is published as: A device for testing the thermal insulation performance of coatings. The public document can test samples with different coating thicknesses, but the device in the public document can only test a large number of samples by setting a large number of push rod motors and a large number of electric heaters, resulting in too many electronic parts inside the device, which increases the difficulty and cost of subsequent production of the device in the public document. In addition, the device in the public document cannot fix the position of the placed samples. When the samples are heated, the expanded samples will squeeze the rubber pads due to the principle of thermal expansion and contraction, causing damage to the rubber pads, thereby affecting the effect of the thermal insulation test. Based on this, the utility model designs a device for testing the thermal insulation performance of coatings to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 , Figure 3 , Figure 4 As shown, the device includes a shell 1, a support net 2 and a partition 3, the support net 2 is fixedly arranged at the lower end of the shell 1, the partition 3 arranged at the lower end of the support net 2 is fixedly connected to the shell 1, a heating component 4 is arranged at the bottom end of the shell 1, a blocking component 5 is fixedly arranged at the top of the shell 1, and mounting holes 6 are integrally arranged from left to right inside the partition 3, the heating component 4 includes a heating pipe 401 fixedly arranged at the bottom end of the shell 1, a controller 402 is fixedly arranged on the right side of the outer wall of the shell 1, and the blocking component 5 includes a baffle 501 fixedly arranged inside the shell 1 from left to right, and the baffle 501 passes through the supporting net 2, the bottom of the baffle 501 is fixedly connected to the top of the partition 3, an electric push rod 502 is fixedly arranged on the top of the shell 1, the head end of the electric push rod 502 passes through the shell 1, a mounting plate 503 is fixedly arranged on the bottom of the electric push rod 502, a blocking plate 504 is arranged on the lower end of the mounting plate 503 from left to right, a spring 505 is fixedly arranged between the left and right sides of the top of the blocking plate 504 and the mounting plate 503, a temperature sensor 506 is fixedly arranged inside the mounting plate 503 from left to right, and a clearance hole 507 is integrally arranged inside the blocking plate 504.

[0029] The staff first places the samples with different thicknesses of oil on the support net 2, and then closes the sealing plate 16. Then, by using the controller 506, the heating tube 401, the electric push rod 502 and the temperature sensor 506 are turned on respectively. The heat generated by the heating tube 401 passes through the mounting hole 6 through the support net 2 to heat the sample. The electric push rod 502 pushes the mounting plate 503 together with the blocking plate 504 to clamp and fix the sample on the support net 2. The reaction force of the sample causes the blocking plate 504 to squeeze the spring 505 to deform. The rebound force of the spring 505 causes the blocking plate 504 to deform. 4 applies soft clamping force to the sample, and then fixes the position of the sample on the support net 2. At this time, the hole 507 makes room for the temperature sensor 506 to detect the sample temperature. At the same time, the blocking plate 504 isolates the temperature of the sample area detected by the temperature sensor 506 from the outside world, avoiding the temperature sensor 504 from erroneously detecting the outside temperature, ensuring the stability of the sample temperature detected by the temperature sensor 504. The temperature sensor 504 then transmits the detected temperature to the controller 402, so that the staff can know the insulation status of samples coated with different thicknesses of coatings at the same temperature. When the sample expands due to heat, the sample will squeeze the blocking plate 504 and move along the direction of the mounting plate 503, which not only ensures that the blocking plate 504 is always in a tight fit with the top of the sample, but also ensures the normal expansion of the sample due to heat. Avoid the blocking plate 504 from crushing the sample.

[0030] Example 2

[0031] like Figure 2 , Figure 3 , Figure 5As shown, the baffle 501 divides the interior of the shell 1 into a number of storage compartments, the size of the cross-section of the storage compartment when viewed from above is consistent with the size of the cross-section of the blocking plate 504 when viewed from above, the mounting hole 6 and the clearance hole 507 are both through-hole designs, the temperature sensor 506, the heating tube 401 and the electric push rod 502 are connected to the controller 402 through wires, a cover body 7 is fixedly provided at the rear end of the shell 1, the exhaust holes 8 integrally arranged from left to right inside the rear end of the shell 1 are through-hole designs, the clearance holes 507 correspond one-to-one with the temperature sensor 506 and the mounting hole 6, a connecting plate 11 is fixedly provided at the front end of the cover body 7, the size of the cross-section of the connecting plate 11 when viewed from the front is consistent with the size of the cross-section of the cover body 7 when viewed from the front, the placement holes 9 integrally arranged from left to right inside the front end of the connecting plate 11 are through-hole designs, and the placement holes The hole 9 and the exhaust hole 8 are in a mutually overlapping design state, a cavity 12 is integrally arranged inside the connecting plate 11, a solenoid valve 13 is fixedly penetrated through the middle side of the rear end of the connecting plate 11 by sealant, the solenoid valve 13 is connected to the controller 402 by a wire, a semiconductor refrigerator 14 is fixedly penetrated through the rear end of the cover body 7, the semiconductor refrigerator 14 is connected to the controller 402 by a wire, the mounting hole 6 and the baffle 501 are in a mutually staggered design, and the mounting hole 6 and the storage compartment inside the shell 1 correspond one to one to each other, a sealing plate 16 is arranged on the left side of the front end of the shell 1 through a hinge and on the right side through a lock, a pressure sensor 15 is fixedly arranged on the left side inside the mounting plate 503, the pressure sensor 15 and the baffle 501 on the left side correspond one to one to each other, and the pressure sensor 15 and the controller 402 are connected by a wire.

[0032] According to the operation method in Example 1, when the electric push rod 502 pushes the mounting plate 503 to move downward, until the baffle 501 on the left side exerts a squeezing force on the pressure sensor 15, the pressure sensor 15 is activated. The pressure sensor 15 is a thin film pressure sensor, and the electric push rod 502 stops running. At this time, the bottom surface of the mounting plate 503 and the top surface of the baffle 501 are in a tightly fitted state, preventing external gas from being discharged from the position between the mounting plate 503 and the baffle 501 into the detection area of ​​the temperature sensor 506. When the sample is in the heat insulation test, the staff can use the controller 402 to make the semiconductor refrigerator 14 cool the gas inside the cover body 7. When the sample test is completed, the staff first closes the heating tube 401 and then opens the solenoid valve 13. At this time, the cold air inside the cover body 7 passes through the solenoid valve 13 and the cavity 12 and is then discharged into the shell 1 through the overlapping placement holes 9 and the exhaust holes 8, thereby cooling the sample. The staff then opens the sealing plate 16, takes out the cooled sample and moves it to the next process.
