Description

Mineralöl oder Mineralöl-Bitumen-Gemisch zur Überschichtung von Flüssigkeiten Bei Verwendung von hochViscosen, auf dein Sperrwasser von Gasbehältern schwimmenden Ölen und Ölgemischen zeigt sich der Übelstand, daß namentlich unter der Mitwirkung von durchblasendem Gas, wie es bei mechanischer Bewegung, z. B. bei der Überfüllung der Behälter, manchmal vorkommt, das Öl oder 'Ölgemisch Wasser aufnimmt und zu einer klumpigen, hydrophoben Emulsion umgebildet wird. Diese Emulsion verbindet sich mit den im Sperrwasser !eintauchenden Wänden des Gasbehälters nicht mehr in gleicher Weise wie das Öl oder Ölgemisch, so daß die Überschichtung des Sperrwassers den Zweck des Rostschutzes nicht mehr voll erfüllen kann. In besonderer Weise ist die Bildung einer hydrophoben Emulsion bei der Überschichtung des inneren Sperrwassersees eines Gasbehälters zu befürchten, weil dort das Gas, welches die Emulgierung beschleunigt, ständig auf das Öl oder Ölgemisch einwirkt.Mineral oil or mineral oil-bitumen mixture for covering liquids When using high viscoses, floating on your sealing water from gas containers Oils and oil mixtures show the evil that especially with the cooperation of blowing gas, as it occurs with mechanical movement, e.g. B. in overcrowding the container, sometimes occurs, takes up the oil or 'mixture of oils and water and becomes one lumpy, hydrophobic emulsion is formed. This emulsion combines with the walls of the gas container that are immersed in the sealing water! Way as the oil or oil mixture, so that the layering of the sealing water the Can no longer fully fulfill the purpose of rust protection. In a special way is that Formation of a hydrophobic emulsion at the layering of the inner sealing water lake fear of a gas container, because there the gas, which accelerates the emulsification, constantly acts on the oil or oil mixture.

Nun wurde ;gefunden, daß, wenn mär Mineralöl oder einem Gemisch. von hochviscosem Mineralöl und Bitumen eine geringe Menge von hydrophilen öllöslichen Emulgatoren zumischt, die unter der Menge bleibt, die zum Ernulgieren dieses Öls nötig wäre, die gegenteilige Wirkung eintritt, nämlich daß das Öl an wasserabstnßender Kraft gewinnt. Durch entsprechende Dosierung bei jedem Öl und bei jedem Gemisch von Öl und Bitumen, die im einzelnen Fall verschieden sein kann, läßt sich ohne weiteres diejenige Menge von Emulgator feststellen, die die wasserabstoßende Wirkung des Öls auch unter Mitwirkung von Gas erhöht und dadurch die ungewollte Emulgierung der zum. Rostschutz auf das Sperrwasser aufgebrachten überschichtungsflüssigkeit zuverlässiz verhindert. B eispiel Einem öl-Asphalt-Gemisch von 95 Gewichtsteilen hochviscosem Mineralöl, Siedebeginn 3oo° C, Viscosität 2 nach E n g 1 e r bei 5o° C, Stockpunkt - 20°, q. Gewichtsteile Petroleumpech vom Schmelzpunkt 5o° nach K. S., wird r Gewichtsteil Laurilsulfosäure zugefügt, wodurch ein Gemisch entsteht, das bei einstündigem Rühren mit Wasser unter Zuleitung von Leuchtgas kein Wasser aufnimmt, während die 99 Gewichtsteile Öl und Bitumen schon nach 20 Minuten gleichartigem Rühren durch Wassereinschluß sich zu einer dikken Paste verwandeln würden.Now it has been found that if mar mineral oil or a mixture. from highly viscous mineral oil and bitumen contain a small amount of hydrophilic oil-soluble Mixing in emulsifiers, which remains below the amount required to emulsify this oil it would be necessary to have the opposite effect, namely that the oil is more water-repellent Strength gains. With the appropriate dosage for every oil and mixture of oil and bitumen, which can be different in individual cases, can be done without further determine the amount of emulsifier that has the water-repellent effect of the oil, even with the help of gas, and thereby unwanted emulsification the for. Anti-rust coating liquid applied to the sealing water reliably prevented. Example An oil-asphalt mixture of 95 parts by weight Highly viscous mineral oil, initial boiling point 3oo ° C, viscosity 2 after E n g 1 e r at 5o ° C, pour point - 20 °, q. Parts by weight of petroleum pitch with a melting point of 50 ° according to K. S., r part by weight of lauril sulfonic acid is added, creating a mixture, which is no water when stirring with water for one hour while supplying luminous gas absorbs, while the 99 parts by weight of oil and bitumen are similar after just 20 minutes Stirring through the inclusion of water would turn into a thick paste.

Die neue überschichtungsflüssigkeit kann mit Vorteil nicht nur bei Gasbehältern, sondern auch für sonstige überschichtungs- und Absperrzwecke benutzt werden, z. B. für Flüssigkeitsverschlüsse aller Art, zum Abdecken von Flüssigkeiten zwecks Vermeidung von Stoffverlusten u. dgl. m.The new coating fluid can be beneficial not only for Gas containers, but also used for other overlay and shut-off purposes be e.g. B. for liquid closures of all kinds, for covering of liquids in order to avoid material losses and the like.
