Abstract

En blanding, ment for å danne et lekkasjetett og Ikke- tokslsk dekke (A) på en væske (B) som avgir toksiske damper eller emanasjoner ved fordamping eller reaksjon med atmosfæriske stoffer tilveiebringes l form av en blanding omfattende (C) en væske med lavt damptrykk som er blandbart eller ublandbart med væsken (B) og som er kjemisk Inert med henblikk på den sistnevnte; og (D) faste partikler med lav densitet som er Inerte med henblikk på væskene (B) og (C) og som velges for å gjøre det mulig å ake forskjellen l densitet for væsken (C) med henblikk på væsken (B) og for å tilveiebringe en blanding (A), l stand til å flyte på overflaten av væsken (B), selv hvis det benyttes en væske (C) som er blandbar med væsken (B) og/eller som har en densitet l området for, eller sågar større enn, den til den sistnevnte, Idet blandbarhet for væsken (C) med væsken (B) i dette tilfellet forhindres ved den forutgående fuktlng av de faste partikler (D) med væsken (C).A mixture, intended to form a leakproof and Non-toxic cover (A) on a liquid (B) which emits toxic vapors or emanations by evaporation or reaction with atmospheric substances is provided in the form of a mixture comprising (C) a low vapor pressure which is miscible or immiscible with the liquid (B) and which is chemically Inert for the latter; and (D) low density solid particles which are inert for the liquids (B) and (C) and selected to allow the difference in density of the liquid (C) for the liquid (B) and for providing a mixture (A) capable of flowing on the surface of the liquid (B), even if a liquid (C) which is miscible with the liquid (B) and / or having a density in the region of is used, or even larger than that of the latter, since in this case miscibility of the liquid (C) with the liquid (B) is prevented by the prior wetting of the solid particles (D) with the liquid (C).
