| 摘要 |
<p>The invention concerns an organosilic system with disincrustant action characterised in that it comprises: an ingredient (A) consisting in a polyorganosiloxane composition, hardenable into a silicon elastomer at room temperature (23 °C) or under the effect of a temperature higher than room temperature, at least partially cross-linked or not, permeable to water vapour; and an ingredient (B), which is hydrophilic and osmotically active, consisting of an active disincrustant substance (B1) on its own or combined with an auxiliary hydrophilic agent (B2), homogeneously dispersed in the silicon ingredient (A); the system is further characterised in that the active disincrustant substance is released in the course of time, in an aqueous medium, out of the silicon ingredient (A) hardened into elastomer, according to kinetics substantially of zero order.</p> |
