Description

Technical Field

[0001] This utility model relates to the technical field of coating performance testing equipment, specifically a climate aging test chamber for coating testing. Background Technology

[0002] A climate aging test chamber for coating testing is a sophisticated environmental simulation device. Its core function is to accelerate the reproduction and intensify the aging and destructive effects of the natural environment on coatings under highly controlled laboratory conditions. Its core value lies in predicting the performance degradation that coating products may undergo in long-term exposure to real outdoor environments, such as loss of gloss, fading, chalking, cracking, peeling, blistering, or decreased adhesion, through artificial acceleration in a relatively short period of time.

[0003] When using this equipment, the coating samples to be tested are securely installed on the sample rack inside the test chamber according to the preset spacing and orientation, ensuring that all sample surfaces are uniformly exposed to the light source and environmental conditions. Subsequently, the operator sets and starts the test cycle program in the equipment's control system. This program typically consists of multiple stages such as light exposure, darkness, spraying, high temperature, and high humidity, combined in a specific sequence and time combination. Throughout the entire test cycle, the equipment runs and cycles through the set functions, while the external environment continuously monitors and records the environmental parameters inside the chamber. After the test, the samples are removed, and their appearance and physical property changes are evaluated. The results are compared with untested control samples or materials with known properties to obtain the weather resistance and expected service life of the coating product.

[0004] In existing equipment, some climate aging test chambers only have one test area, and their limited space can only accommodate a small number of finished paint samples. This means that each test can only evaluate a single paint type. However, different paints require different simulated service environments, necessitating multiple rounds of independent testing. Since each round of aging test has a long cycle, it affects testing efficiency and operational convenience. On the other hand, some equipment has fixed ultraviolet lamps. Some paints have special requirements for ultraviolet intensity or spectral distribution, and fixed ultraviolet lamps cannot be well adapted. Furthermore, during equipment maintenance, the narrow internal space of the test chamber causes significant inconvenience to operators when repairing or replacing ultraviolet lamps, making the disassembly process difficult and further affecting equipment maintenance efficiency. Therefore, we urgently need a climate aging test chamber for paint testing to solve the above problems. Utility Model Content

[0005] This utility model provides a climate aging test chamber for coating testing. By setting up a partition, it solves the problem that the test can only evaluate a single type of coating, which is mentioned in the background art. It improves the testing efficiency and the convenience of operation. By setting up a detachable placement plate, it solves the problem that the fixed ultraviolet lamp tubes cannot be well adjusted for adaptability, and the narrow interior of the test chamber affects the maintenance efficiency.

[0006] This utility model provides the following technical solution:

[0007] A climate aging test chamber for coating testing includes a chamber body for testing the climate aging of coatings, wherein the chamber body is provided with a test chamber and a water treatment chamber, and further includes: a tray slidably disposed in the test chamber, a partition for dividing areas being fixedly connected to the inner wall of the test chamber, a slide rail adapted to the partition being fixedly connected to the upper part of the tray, and the lower part of the partition being slidably connected to the slide rail; and slots for mounting test specimens arranged linearly and equidistantly on the inner wall of the test chamber.

[0008] As a preferred technical solution of this utility model, the test piece includes a placement plate that can be detachably installed in a slot. At least two sets of ultraviolet lamps are fixedly installed on the lower part of the placement plate, and a limiting area is formed when the end of the placement plate is inserted into the slot.

[0009] As a preferred technical solution of this utility model, the number of partitions is at least two sets, and the two sets of partitions are arranged linearly and equidistantly in the test chamber. When the tray is located in the test chamber, an independent test area is formed between adjacent partitions.

[0010] As a preferred technical solution of this utility model, at least three sets of crossbars for supporting the placement plate are fixedly connected on the partition plate. When the placement plate is inserted into the slot, its lower part abuts against the upper part of the crossbars and forms a support area.

[0011] As a preferred technical solution of this utility model, the water treatment chamber is mainly composed of a water storage chamber and a drainage chamber. A spray pipe is fixedly connected to the partition, and multiple sets of nozzles are arranged linearly and equidistantly on the spray pipe. The input end of the spray pipe is connected to the output end of the water pump in the water storage chamber. When the water pump is working, the nozzles on the spray pipe spray water and form a spray area.

[0012] As a preferred embodiment of this utility model, the tray is provided with several through holes for draining water.

[0013] As a preferred embodiment of this utility model, guide rails are symmetrically installed on the inner wall of the test chamber, and the two sides of the tray are slidably connected to the guide rails respectively.

[0015] 1. The climate aging test chamber for coating testing can be divided into multiple independent test areas by setting multiple partitions, which changes the situation of existing equipment with only one test area. It can simultaneously accommodate a variety of different coating samples for testing. Each sample can simulate different service environments in its own independent test area without the need for multiple rounds of independent testing, which greatly shortens the testing time and improves the testing efficiency.

[0016] 2. The climate aging test chamber for coating testing features multiple placement slots, which makes the adjustment and maintenance of ultraviolet lamps more convenient. When it is necessary to replace different types of ultraviolet lamps according to the special requirements of different coatings for ultraviolet intensity or spectral distribution, simply remove the placement plate from the slot, replace it, and then insert it again. There is no need to operate inside the narrow chamber. It also facilitates the inspection and maintenance of ultraviolet lamps, improving the availability and maintenance efficiency of the equipment.

[0017] 3.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Reference Figures 1-6 A climate aging test chamber for coating testing includes a chamber 1 for testing the climate aging of coatings. The chamber 1 contains a test chamber and a water treatment chamber. The water treatment chamber mainly consists of a water storage chamber and a drainage chamber. The bottom of the test chamber is connected to the drainage chamber. A baffle is provided between the drainage chamber and the water storage chamber. A drainage pipe connected to an external collection box is installed in the drainage chamber. An inlet pipe connected to an external water inlet pipe is installed on the water storage chamber. A water pump for water supply is also provided in the water storage chamber. The water pump is preferably a high-flow-rate multistage centrifugal pump. Because multiple spray pipes 9 need to operate simultaneously during the test to simulate spraying in different test areas, the high-flow-rate multistage centrifugal pump can provide sufficient water flow to ensure that the nozzles 10 can stably spray out sufficient water, which helps to more realistically present the aging condition of the coating under extreme rainfall conditions.

[0029] Furthermore, the enclosure 1 has functions such as temperature and humidity control, timing, data recording and storage, alarm function, and automatic operation function. These functions are existing technical solutions and will not be described in detail here.

[0030] In this embodiment, the test chamber inside the housing 1 is designed for climate aging tests of the coating, while the water treatment chamber is responsible for water supply and wastewater treatment. This makes the functional layout of the equipment more reasonable and improves the integration and ease of use of the equipment.

[0031] It also includes a tray 2 that is slidably disposed in the test chamber. Guide rails 12 are symmetrically installed on the inner wall of the test chamber. The two sides of the tray 2 are slidably connected to the guide rails 12 respectively. Several through holes 11 for draining water are opened on the tray 2.

[0032] Here, tray 2 is used to place the coating sample, providing a stable support platform for the sample. Tray 2, together with the guide rail 12 on the inner wall of the test chamber, allows the operator to easily slide tray 2 out of or push it into the test chamber, which greatly facilitates the placement and removal of the sample, reduces the difficulty of operation, and improves work efficiency. In addition, the through hole 11 on tray 2 can drain excess water generated during the spraying process in a timely manner, preventing water from accumulating on tray 2 and changing the test environment of the sample, thus ensuring the stability and reliability of the test conditions.

[0033] The inner wall of the test chamber is fixedly connected with partitions 3 for separating areas. The upper part of the tray 2 is fixedly connected with a slide rail 4 that is compatible with the partitions 3, and the lower part of the partitions 3 is slidably connected to the slide rail 4. There are at least two sets of partitions 3, and the two sets of partitions 3 are arranged linearly and equidistantly in the test chamber. When the tray 2 is located in the test chamber, an independent test area is formed between adjacent partitions 3.

[0034] In this embodiment, there are four partitions 3 and four slide rails 4. When the sample is placed on the tray 2 and moved into the test chamber, the partitions 3 can automatically divide the tray 2 into multiple independent test areas. Each test area can independently conduct different climate aging tests, which meets the need to test multiple coating samples at the same time. There is no need to conduct multiple rounds of independent testing, which significantly improves the testing efficiency. Since each test area is independent of the others, the mutual interference between different sample test environments is avoided, ensuring the accuracy of the test results.

[0035] Furthermore, the slide rail 4 is slidably connected to the lower part of the partition 3. When the tray 2 is pushed into or pulled out of the test chamber, the partition 3 can slide smoothly along the slide rail 4, ensuring the stability of the movement of the tray 2. At the same time, it also ensures the effective separation of the test area by the partition 3, avoiding gaps between the test areas caused by the movement of the tray 2, which would affect the independence of the test environment.

[0036] It should be noted that each independent test area is equipped with temperature and humidity sensors to monitor the sample conditions. This is a standard technical solution and will not be elaborated on further here.

[0037] A spray pipe 9 is fixedly connected to the partition 3, and multiple sets of nozzles 10 are arranged linearly and equidistantly on the spray pipe 9. The input end of the spray pipe 9 is connected to the output end of the water pump in the water storage chamber. When the water pump is working, the nozzles 10 on the spray pipe 9 spray water and form a spray area.

[0038] In this embodiment, spray pipes 9 are installed on all four sets of partitions 3, and two sets of spray pipes 9 are provided between two adjacent sets of partitions 3, thereby forming a symmetrical spraying area, so as to spray water evenly onto the sample to simulate a natural rainfall environment.

[0039] Furthermore, the use of a high-flow-rate multi-stage centrifugal pump allows for independent control of the spray pipes 9 and nozzles 10 corresponding to each independent test area. By adjusting the power and operating time of the pump, different spray intensities and frequencies can be achieved, meeting the needs of different coating samples for simulating rainfall environments.

[0040] Slots 5 for mounting test specimens are linearly and equidistantly arranged on the inner wall of the test chamber. The test specimens include a placement plate 6 that is detachably installed in the slot 5. At least two sets of ultraviolet lamps 7 are fixedly installed on the lower part of the placement plate 6. When the end of the placement plate 6 is inserted into the slot 5, a limiting area is formed. At least three sets of crossbars 8 for supporting the placement plate 6 are fixedly connected to the partition plate 3. When the placement plate 6 is inserted into the slot 5, its lower part abuts against the upper part of the crossbar 8 and forms a support area.

[0041] In this embodiment, each independent test area is equipped with multiple sets of slots 5 at different heights, which makes the installation of the placement plate 6 more flexible. Different installation positions can be selected according to test requirements to adjust the irradiation angle and distance of the ultraviolet lamp 7 and meet the testing requirements of different coating samples. The placement plate 6 is the mounting carrier for the ultraviolet lamp 7 and is installed in the slot 5 in a detachable manner, which makes the replacement and maintenance of the ultraviolet lamp 7 very convenient. Operators do not need to operate inside the narrow box 1. They can simply remove the placement plate 6 from the slot 5 to replace or repair the ultraviolet lamp 7, which reduces the difficulty of operation and improves the maintenance efficiency and availability of the equipment.

[0042] Here, the ultraviolet lamp 7 is used to simulate ultraviolet irradiation in sunlight. The setting of multiple sets of ultraviolet lamps 7 can provide more uniform and sufficient light, ensuring that the light conditions received by the sample are consistent and improving the reliability of the test results. The detachable installation of the placement plate 6 allows for easy replacement of different types of ultraviolet lamps 7 according to the special requirements of different coatings for ultraviolet intensity or spectral distribution, enhancing the adaptability of the equipment.

[0043] Furthermore, the crossbar 8 provides additional support for the placement plate 6, and the resulting support area effectively prevents the placement plate 6 from shaking or falling off during the test, ensuring the stability of the irradiation position of the ultraviolet lamp tube 7 and ensuring the accuracy of the test.

[0044] In this invention, during use, the tray 2 is first slid out of the test chamber along the guide rail 12. Different coating samples are placed on the tray 2 at their respective independent test areas. Based on the UV requirements of different coating samples, a suitable UV lamp 7 is selected and installed on the placement plate 6. Then, the placement plate 6 is inserted into the corresponding slot 5 on the inner wall of the test chamber. At this time, the lower part of the placement plate 6 abuts against the crossbar 8 and forms a support. Next, the tray 2 is pushed into the test chamber along the guide rail 12, causing the lower part of the partition 3 to slide on the slide rail 4 on the upper part of the tray 2. The partition 3 is used to clearly define the UV lamps in the test chamber. The test area marked on tray 2 is used to irradiate the paint sample with ultraviolet lamp 7 during the test to simulate a light environment. By controlling the water pump in the water storage chamber, the nozzles 10 on the spray pipe 9 are activated to provide corresponding spraying conditions for different independent test areas. Excess water generated during the test is discharged through the through hole 11 on tray 2 into the drainage chamber of the water treatment chamber and then discharged through the drain pipe. After the test, tray 2 is slid out and the paint sample is taken out for analysis. If it is necessary to replace or repair the ultraviolet lamp 7, simply remove the placement plate 6 from the slot 5.

[0045] Components not described in detail in this article are existing technologies.

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.
