Description

Technical Field

[0001] This utility model relates to the technical field of gypsum water retention rate tester, and in particular to a gypsum water retention rate tester with temperature control function. Background Technology

[0002] In the field of building materials, gypsum, as an important cementitious material, has a water retention rate that is a key indicator for evaluating product quality and performance. The water retention rate directly affects the workability and hardened physical and mechanical properties of gypsum. A higher water retention rate ensures that gypsum maintains good plasticity and workability during construction, preventing problems such as cracking and reduced strength caused by excessive moisture loss. Currently, gypsum water retention rate testers based on the vacuum filtration principle are widely used in the industry. These instruments apply negative pressure to the gypsum slurry, causing water to be extracted through filter paper, and then calculate the water retention rate based on the mass change before and after filtration.

[0003] However, existing gypsum water retention rate testers have significant shortcomings in practical use. Most lack temperature control, while ambient temperature significantly affects the hydration reaction and water evaporation of gypsum. The water retention performance of gypsum varies greatly at different temperatures; for example, increased temperature accelerates the hydration process and water evaporation, leading to changes in water retention rate. Conversely, decreased temperature slows down both hydration and evaporation. If temperature cannot be controlled during testing, the obtained water retention rate data cannot accurately reflect the true performance of gypsum in real-world applications, resulting in low accuracy and reliability of the test results and failing to meet the needs of precise performance evaluation in practical engineering projects. In construction engineering, ambient temperatures vary considerably across different regions and seasons. Relying on data from existing temperature-uncontrolled testers for gypsum material selection and mix design may lead to engineering quality problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a gypsum water retention rate tester with temperature control function, so as to solve the problem mentioned in the background art that most testers do not have temperature control function, while ambient temperature has a significant impact on the hydration reaction and water evaporation of gypsum.

[0009] As a further embodiment of this utility model, a heat dissipation hole is provided on one side of the main body of the gypsum water retention rate tester, and a cooling fan is installed inside the heat dissipation hole. The cooling fan plays a role in heat dissipation.

[0014] (III) Beneficial Effects

[0015] This utility model provides a gypsum water retention rate tester with temperature control function, which has the following beneficial effects:

[0016] 1. This gypsum water retention rate tester with temperature control function, through the setting of temperature control mechanism and temperature sensors, when the power is turned on, uses the temperature controller to control the heating mesh in the cavity inside the heating jacket to heat up and heat the surface of the cloth funnel on one side. After heating it to a suitable temperature, several temperature sensors installed on the surface of the cloth funnel are used to detect the surface temperature in real time, thereby achieving the effect of precise control of the surface temperature of the cloth funnel and avoiding the influence of temperature on the accuracy of the test results.

[0017] This gypsum water retention rate tester with temperature control features a sealing mechanism. During use, heat dissipates from the top of the cloth funnel, making it difficult for the temperature control system to accurately maintain the temperature inside the funnel. Therefore, a sealing cap is inserted into the top of the funnel, and a rubber sealing ring on the lower surface of the cap fits tightly against the inner wall of the funnel. Combined with a support spring installed inside the rubber sealing ring, this improves the tightness of the connection between the rubber sealing ring and the external support structure, thereby extending the service life of the rubber sealing ring. This sealing structure significantly enhances temperature control, bringing the test temperature closer to the set value and ensuring consistent test conditions. Attached Figure Description
