Among them, the external stirring type hydration heat tester has a disadvantage that it cannot measure hydration heat release quantity of the slurry at an early stage; the internal stirring type hydration heat tester has a disadvantage in that the heat generated by the internal stirring rod while stirring the slurry may cause errors in the test results. The test method of the non-stirring hydration heat tester is that the injector with solution is firstly sleeved into the test bottle, the sample to be tested in the test bottle is contacted with the needle tube, after the tester is started, the liquid is extruded out of the injector by means of extrusion, the solution is mixed with the solid, and the hydration heat is simultaneously measured. The method is simple to operate, and avoids the problems of the stirring method. However, since conventional syringe needles are typically single-bore hollow needles, insufficient dissolution of solids and liquids often occurs, which greatly affects the accuracy of hydration heat testing.
Therefore, there is a need for a new hydration heat measurement syringe that solves the above-mentioned problems of the prior art.
