Background technique

The physical and chemical properties of cement directly affect the strength and durability of buildings, and are related to the safety of life and national property. Therefore, the detection of cement performance indicators is of great significance. Among them, the setting time of cement is one of the important parameters of cement performance. The purpose of measuring the setting time of cement is to determine whether the setting time of cement is within the specified range. Our commonly used cement setting time tester is a completely manual reading test instrument, which is widely used at present. The test method of this instrument is to release the test needle artificially every once in a while, and record each time by manually reading the scale data. The depth of sinking, according to the national standard, finally gets the initial setting and final setting time of cement, but the test needle is easily affected by external force due to the influence of air buoyancy during use, and cannot do a complete free fall movement, resulting in inaccurate testing , so a new digital scale cement setting time tester is needed.

The ruler frame is equipped with a digital display component that can display the relative moving distance between the ruler frame and the ruler bar. There is a test needle at the bottom of the ruler bar. When the test needle on the ruler bar sinks into When measuring the setting time of cement paste, the sinking distance of the test needle will be digitally displayed on the ruler frame, the reading is more accurate and reliable, and the use is more convenient. However, the device is easily affected by external forces during use and the measurement is not enough. precise.

At present, the existing digital display ruler type cement setting time tester is inconvenient to use and is not conducive to popularization and use.
