Description

Technical Field

[0001] This utility model relates to the field of performance testing technology for two-component sealants, and in particular to a detachable two-component concrete sealant pot life tester. Background Technology

[0002] In practical engineering, concrete construction joints and cracks are quite common. These are typically filled with sealant to achieve reinforcement. When testing the performance of two-component sealants, such as evaluating their pot life, methods like direct pouring, pouring the sealant into a dispensing bucket or plastic bag, and then squeezing it out are often used to observe the sealant's early curing behavior and changes in flowability. The point at which the flow rate is ≤50mL / min is recorded as the pot life of the two-component sealant.

[0003] In testing the pot life of sealants, the specific composition of the experimental equipment, such as the material of the extrusion container, was not clearly defined. Research and experiments revealed that differences in the extrusion container and the force applied by the experimenter can affect the extrudability of the sealant. This results in a rather coarse measurement of the pot life, leading to errors in the evaluation of the sealant's curing performance and affecting the accuracy of the results. Furthermore, improper operation or lack of protective measures during extrusion can cause the sealant to come into contact with the experimenter's skin, potentially causing injury. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a detachable two-component concrete sealant pot life tester. The tester is entirely detachable. By setting a stopwatch and marking the funnel and sample container with scales, it can accurately measure the pot life of the two-component sealant, increasing experimental precision. The funnel and sample container are replaceable; during cleaning, the screws can be loosened to tilt the metal container for easy cleaning. The instrument is highly flexible; the cap, funnel, and sample container are all easy to clean and reusable, saving costs. The tester is highly practical, effective, and easy to promote and use.

[0024] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1

[0026] Combination Figure 1-4This embodiment of a detachable two-component concrete sealant pot life tester includes a metal frame 3 and a metal bucket 4. The metal bucket 4 is mounted on the metal frame 3 by screws 6, and a cap 1 that mates with the metal bucket 4 is provided on the metal bucket 4. A sample bowl 7 is provided on the metal frame 3 and below the metal bucket 4. The outer side of the sample bowl 7 is provided with a first scale mark 8. A funnel 9 is provided inside the metal bucket 4. A through hole is opened at the bottom of the metal bucket 4. The lower part of the funnel 9 passes through the through hole and is snapped into the bottom of the metal bucket 4. A liquid stopping device 10 is provided at the lower part of the funnel 9. The surface of the funnel 9 is provided with a second scale mark 12. A multi-functional stopwatch 5 is installed on the outer wall of the metal bucket 4.

[0027] The testing instrument in this embodiment features a simple structure, easy operation, and reasonable design. By setting a stopwatch and marking graduations in both the funnel 9 and the sample bowl 7, the usable period of the two-component sealant can be accurately measured, increasing the accuracy of the experiment. The entire testing instrument is detachable for easy storage and can be replaced promptly if damaged. All parts are reusable, saving costs. The funnel 9 and sample bowl 7 are replaceable, and the metal container can be tilted by loosening the screw 6, making the instrument highly flexible. The cap 1, funnel 9, and sample bowl 7 are all easy to clean and reusable, saving costs. The equipment is highly practical, has good performance, and is easy to promote and use.

[0028] The multi-function stopwatch 5 has countdown and 30-second countdown functions.

[0029] A handle 2 is fixedly connected to the top of the cap 1.

[0030] The surface of the funnel 9 is provided with a label bar 11.

[0031] The cap 1, metal frame 3 and metal bucket 4 are made of stainless steel, the sample bowl 7 is made of polytetrafluoroethylene, and the funnel 9 is a glass container. Both the funnel 9 and the sample bowl 7 are made of high and low temperature resistant materials, which can adapt to different experimental temperatures, and the sample bowl 7 and the funnel 9 can be reused.

[0032] The metal frame 3 includes a base and supports fixed on both sides above the base. The side wall of the metal barrel 4 and the supports are provided with threads that cooperate with screws 6. There are two screws 6, which pass through the supports on both sides and extend into the interior of the metal barrel 4.

[0033] The inside of the funnel 9 is used to hold the two-component sealant sample.

[0034] In practical use, the sample information is marked on the label 11 of the funnel 9. The funnel 9 is placed in the metal bucket 4, and the sample bowl 7 is placed on the base of the metal frame 3, with the sample bowl 7 aligned with the bottom of the funnel 9. A suitable dosage is selected, and the well-stirred two-component sealant is immediately poured into the funnel 9. The liquid stop device 10 is turned on, and the 30-second countdown function of the stopwatch 5 is activated and started. The cap 1 is closed, and the scale 8 of the sample bowl 7 is observed. When the 30-second countdown ends, the liquid stop device 10 is turned off. If the sealant in the sample bowl is greater than 25 mL, the sample bowl is immediately replaced, and the above steps are repeated until less than 25 mL of sealant sample flows out in 30 seconds. The time taken is recorded as the pot life of the two-component sealant, and the early curing time of the sealant is evaluated. After the experiment, stopwatch 5 should be zeroed immediately, and funnel 9 and sample bowl 7 should be removed and cleaned. If the prepared sealant does not stick to funnel 9 and sample bowl 7, they can be removed directly after the sealant has basically cured. If metal bucket 4 needs to be cleaned, loosen screw 6 and tilt metal bucket 4 to facilitate cleaning.

[0035] In addition, the tester of this invention can also test the flow rate of sealant at any time. By turning on the positive timing function of the stopwatch 5 and turning on the liquid stop device 10, the flow rate of sealant can be calculated based on the amount of sealant in the sample bowl 7, which can be used to judge the change in the fluidity of sealant.

[0036] This invention features a simple structure, easy operation, and reasonable design. By setting a stopwatch and marking graduations in both the funnel and sample container, the pot life of the two-component sealant can be accurately measured, increasing experimental precision. The entire device is detachable, and the funnel and sample container are replaceable. During cleaning, the screws can be loosened to tilt the metal container for easy cleaning. The instrument offers high overall flexibility; the cap, funnel, and sample container are all easy to clean and reusable, saving costs. The equipment is highly practical, effective, and easy to promote. The cap, metal frame, and metal container are made of stainless steel, which has excellent corrosion resistance and mechanical strength. During the testing of two-component concrete sealants, stainless steel can resist the corrosive effects of chemicals in the sealant, ensuring the lifespan of the testing instrument. The sample container is made of polytetrafluoroethylene (PTFE), which has advantages such as good chemical stability, resistance to high and low temperatures, and a low coefficient of friction. This allows the sample container to effectively hold the two-component sealant sample without chemical reaction, and also makes sampling and cleaning more convenient. In summary, this utility model is reasonably designed, easy to implement, and can be effectively applied in the pot life test of two-component sealants, ensuring the accuracy of the test results.
