[0002] Superabsorbent polymer (SAP) is a typical functional polymer material. It can absorb hundreds or even thousands of times its own weight in water and has a very strong water-retention capacity, hence it is also known as a super absorbent or high-water-retention agent. In the hygiene field, it is mainly used as a raw material for sanitary napkins and diapers.
[0003] The water absorption rate of superabsorbent polymers is an important indicator for judging the quality of products, so it is necessary to test their water absorption performance. Utility Model Content
[0004] Therefore, in view of the above problems, this utility model proposes a polymer superabsorbent polymer material performance testing mechanism that is simple in structure and can conveniently test the water absorption quality of superabsorbent polymers.
[0005] To achieve the above objectives, the present invention provides a performance testing mechanism for superabsorbent polymer materials, comprising a testing chamber, a workbench inside the testing chamber, a water storage tank on the workbench, a placement box for placing superabsorbent polymer materials above the testing chamber, a bottom-through box with a first filter screen at the bottom, a T-shaped rod at the other end of the placement box, and a lifting cylinder on the testing chamber for raising and lowering the placement box. The extension rod of the lifting cylinder is connected to the T-shaped rod via a connecting device for raising and lowering the placement box.
[0006] A further improvement is that the connecting device includes a connecting rod, the extending rod has a connecting channel, the connecting rod passes through the connecting channel, and a fixing device is provided between the connecting rod and the connecting channel.
[0007] A further improvement is that the fixing device includes symmetrically arranged fixing blocks, the connecting rod has a fixing channel matching the fixing blocks, the extending rod has a sliding channel and is connected to the fixing channel, the fixing blocks are slidably disposed in the sliding channel, the sliding channel is provided with a pushing device to push the fixing blocks into the fixing channel, and the extending rod is provided with a releasing device to release the fixing blocks from the fixing channel.
[0008] A further improvement is that the pushing device includes a spring, one end of which is connected to a fixed block, and the other end of which is connected to the inner wall of the sliding channel.
[0009] A further improvement is that the release device includes a rotating ring, which is rotatably sleeved on the extension rod. Magnets are symmetrically arranged inside the rotating ring and are located in the sliding channel. The fixing block has magnetism that attracts the magnets.
[0010] A further improvement is that the workbench is equipped with a heater for heating the water storage tank.
[0011] A further improvement is made to the following: the testing box is equipped with a water tank, the water tank is equipped with an inlet pipe, the other end of the inlet pipe is connected to a water storage tank, a first water pump is provided between the inlet pipe and the water tank, the bottom of the water storage tank is equipped with an outlet pipe, the other end of the outlet pipe is connected to the water tank, and a second water pump is provided between the outlet pipe and the water tank.
[0012] A further improvement is that a second filter screen is provided at the ports of the water inlet pipe and the water outlet pipe respectively.
[0013] The advantages and beneficial effects of this utility model are as follows:
[0014] With a simple structure, it facilitates the testing of the water absorption capacity of superabsorbent polymers. The placement box, driven by a lifting electric cylinder, enters the water storage tank to absorb water, allowing for easy operation by staff to monitor the water absorption capacity of the superabsorbent polymer. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the performance testing mechanism for superabsorbent polymer materials in this embodiment.
[0016] Figure 2 This is a schematic diagram of the connection device structure in this embodiment. Detailed Implementation
[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0018] like Figure 1-2 As shown, the polymer water-absorbing resin material performance testing mechanism includes a testing box 1, a workbench 2 inside the testing box 1, a water storage cylinder 3 on the workbench 2, a placement box 8 for placing polymers above the testing box 1, the bottom of the placement box 8 is through-hole and has a first filter screen 9 at the bottom, a T-shaped rod 11 at the other end of the placement box 8, and a lifting cylinder 12 on the testing box 1 for driving the placement box 8 to rise and fall. The extension rod 14 of the lifting cylinder 12 is connected to the T-shaped rod 11 through a connecting device to drive the placement box 8 to rise and fall.
[0019] Specifically, the connecting device includes a connecting rod, symmetrically arranged fixing blocks 15, and a rotating ring 13. The extending rod 14 has a connecting channel, through which the connecting rod passes. The connecting rod matches the fixing block 15 and has a fixing channel. The extending rod 14 has a sliding channel 17 and is connected to the fixing channel. The fixing block 15 is slidably disposed in the sliding channel 17. The sliding channel 17 is provided with a spring 16 that pushes the fixing block 15 into the fixing channel. One end of the spring 16 is connected to the fixing block 15, and the other end of the spring 16 is connected to the inner wall of the sliding channel 17. The rotating ring 13 is rotatably sleeved on the extending rod 14. The rotating ring 13 is symmetrically provided with magnets (not shown in the figure), and the magnets are located in the sliding channel 17. The fixing block 15 has magnetism that attracts the magnets. In this process, the polymer is placed into the placement box 8 and weighed. After weighing, the placement box 8 is placed into the testing chamber 1. The connecting rod on the T-shaped rod 11 is then inserted into the connecting channel. The rotating ring 13 is then rotated, causing the magnet and the fixing block 15 to misalign. At this point, the spring 16 returns to its original position, pushing the fixing block 15 into the fixing channel and engaging. This fixes the placement box 8 onto the extension rod 14 of the lifting cylinder 12. The lifting cylinder 12 then operates, moving the placement box 8 downwards into the water storage tank 3, allowing the superabsorbent polymer to absorb water. After absorption, the lifting cylinder 12 returns to its original position, and the rotating ring 13 returns to its original position, causing the magnet to move the fixing block 15 back to its original position, releasing it from the fixing channel. The placement box 8 can then be removed, and the resin inside can be weighed again to determine its water absorption efficiency. This method is convenient for operators and allows for testing of superabsorbent polymers using placement boxes 8 of different specifications.
[0020] In order to test the water absorption performance of polymers at different water temperatures, the workbench 2 is equipped with a heater 4 for heating the water storage tank 3.
[0021] In order to facilitate the addition and return of water to the water storage tank 3, the detection box 1 is equipped with a water tank 5, the water tank 5 is equipped with a water inlet pipe 6, the other end of the water inlet pipe 6 is connected to the water storage tank 3, a first water pump is provided between the water inlet pipe 6 and the water tank 5, the bottom of the water storage tank 3 is equipped with a water outlet pipe 7, the other end of the water outlet pipe 7 is connected to the water tank 5, and a second water pump is provided between the water outlet pipe 7 and the water tank 5.
[0022] To prevent the inlet pipe 6 and outlet pipe 7 from becoming clogged, a second filter screen is provided at the port of the inlet pipe 6 and outlet pipe 7 respectively.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
