Stearic acid for cement treatment
In general, the applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. Stearic acid undergoes the typical reactions of saturated carboxylic acids, a notable one being reduction to stearyl alcohol, and esterification with a range of alcohols. This is used in a large range of manuf… 網頁As a result, a stearic acid was determined to be appropriate based on safety and adequate thermal properties criteria. In order to measure the reduction in engine fuel consumption, a thermal storage system designed for the actual engine was applied to achieve a quick warm-up by releasing stored heat energy directly on the coolant during a cold start.
