[0237] Embodiments of the present disclosure are further defined in the following non-limiting examples. It should be understood that these Examples, while indicating certain embodiments of the disclosure, are given for illustration only. From the above discussion and these examples, one of ordinary skill in the art can ascertain the essential characteristics of this disclosure, and without departing from the spirit and scope thereof, can make various changes and modifications to the embodiments of this disclosure so as to adapt them to various uses and conditions. Accordingly, various modifications of the embodiments of the disclosure in addition to those shown and described herein will become apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims.
[0238] For the first test, the above formulation was used, where the same amount of calcium carbonate powder (0.5 g) was added t...
example 2
[0242] In this test, the same amount of calcium carbonate (CaCO 3 ) powder (0.5 g) was added to a 50 mL aliquot of a 10% solution of each product. After stirring at room temperature, the unreacted CaCO 3 It was filtered from solution, washed with water, dried in an oven, and collected again. Using re-collected CaCO 3 to calculate the amount dissolved, and from this to calculate the CaCO dissolved by each product 3 percentage.
[0243] The numerical results below are reported as a percentage of dissolved CaCO3:
[0244]
[0245] image 3 The results are depicted graphically. For the 10% solution, the performance of the PPE-free formulation was clearly the best of the three products tested. For liquid deliming formulations, more precipitate was recollected than initially added, resulting in a negative dissolution percentage due to the formation of insoluble calcium salts.
example 3
[0247] In this test, the same amount of calcium carbonate powder (0.5 g) was added to 10 mL of water in a separate beaker. While stirring at room temperature, a 10% solution of each product was added in portions to each beaker. Record complete dissolution of CaCO 3 desired volume. The result is as follows.
[0248]
[0249] For unbuffered acidic formulations, 500 mL of solution was added, but complete dissolution was not obtained. The buffered formulation without PPE requires approximately 38 mL of 10% solution, and the liquid deliming agent requires approximately 25 mL to dissolve. In the case of liquid deliming agents, the endpoints were difficult to discern due to the precipitation of calcium salts, as mentioned in previous experiments. exist Figure 4 The results are depicted in .
