Abstract

The liq. is e.g. a lacquer dissolved in water, or a viscous wax; and the spraying zone surrounding one or more spraying nozzles is heated to the working temp. of the liq. to prevent evapn. of that liq. before it reaches the workpiece. The heating of the spraying zone is pref. achieved via a stream of air heated electrically or electromagnetically. One pref. plant includes a heated tank from which the liq. is pumped through a filter to a spraying nozzle surrounded by a duct (a) fed with a stream of hot air from a blower. Duct (a) may also contain baffles in which electric resistance heater coils are located; and the baffles direct the hot air onto the workpiece. When organic solvents are used with the protective lacquers, high costs are involved in preventing environmental pollution. The invention eliminates such costs.

Description

Verfahren und Vorrichtung zum Aufspritzen von flüssigenMethod and device for spraying liquids

Korrosionsschutzmitteln auf metallische Oberflächen Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Auftragen von lösungsmittelfreien flüssigen Korrosionsschutzmitteln, z.B. wasserlöslichen Lacken, höher konsistenten Wachsen oder dergleichen, auf metallische Oberflächen durch Heißspritzen nit einer oder mehreren Spritzdüsen.Corrosion protection agents on metallic surfaces The invention relates to a method and a device for applying solvent-free liquid corrosion protection agents, e.g. water-soluble paints, are more consistent Waxing or the like, on metallic surfaces by hot spraying with a or more spray nozzles.

Das Überziehen der Oberfla:hen metallischer Gegenstände mit flüssigen Korrosionsschutzstow'en durch heißes Aufspritzen ist bekannt. HierfÜr werden im allgemeinen lösungsmittelhaltige Lacke oder auch ldsungsmittelfreie Schutzmittel, wie verflUssigte Wachse, Öle oder wasserlösliche Lacke verwendet, welche in beheizten Vorratsbehältern auf die Jeweilige Verarbeitungstemperatur gehalten von hier mittels einer Pumpe einer Spritzpistole zugeführt werden , häufig unter Zwischenschalung eines Durchlauferhitzers und eines Filters.The coating of the surface of metallic objects with liquid Corrosion protection by hot spraying is known. For this, in general solvent-based paints or solvent-free protective agents, such as liquefied waxes, oils or water-soluble paints used in heated Storage containers kept at the respective processing temperature from here by means of a pump of a spray gun are fed, often with intermediate formwork a water heater and a filter.

Hierbei kann der Nachteil eintreten, daß die heißen Schutzmittel auf dem Wege zwischen der Austrittsdüse der Spritzpistole und dem Werkstück durch Verdunstungswärme, insbesondere bei lösungsmittelhaltigen Stoffen, so stark abkühlen, daß die Partikel nur mit Raumteiperatur auf die zu konservierende Oberfläche auftreffen. Dadurch wird ihre Fillbildung stark verschlechtert. Bei Verwendung von lösungsmittelhaltigen Schutzstoffen bereitet die Abführung der Lösungsmitteldämpfe in die Abluft hinsichtlich der Uiweltschutzvorschriften große Schwierigkeiten. Es sind aufwendige Nachverbrennungs- oder Adsorptionseinrichtungen erforderlich, die hohe Investitions-und Betriebskosten verursachen.This can have the disadvantage that the hot protective agent on the path between the outlet nozzle of the spray gun and the workpiece through evaporation heat, in particular in the case of solvent-based substances, cool down so much that that the particles only hit the surface to be preserved with partial spatial temperature. As a result, their fill formation is greatly impaired. When using solvent-based Protective substances prepares the discharge of the solvent vapors into the exhaust air with regard to the environmental protection regulations great difficulties. There are expensive afterburning or adsorption equipment is required, which has high investment and operating costs cause.

Der Erfindung lie6t die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, womit es ermöglicht wird, flüssige und lösungsmittelfreie Korrosionsschutzstoffe durch Heißspritzen auf ietallische Oberflächen unter Vermeidung eines schädlichen Wärieverlustes aufzubringen.The invention is based on the object of a method and a device to create, which makes it possible to use liquid and solvent-free corrosion protection substances by hot spraying on metallic surfaces while avoiding harmful Apply heat loss.

Gelöst wird die Aufgabe iit den in den Patentansprüchen angeebenen Maßnahmen und Einrichtungen.The object is achieved in the claims specified Measures and facilities.

Dadurch, daß auf Verarbeitungstemperatur erhitzte lösungmittelfreie Konservierungsstoffe verwendet w.rden, z.B. höher konsistente Wachse, Öle oder wasserlösliche Lacke, ergeben sich iit der Erfindun6 gleichiäßiges Zusaiienfließen auf den Materialoberflächen, schnellere Trockenzeiten sowie der Entfall von Anlagen für Nachverbrennung und zum Absaugen schädlicher Dlapfe. Eine Vorwärmung der zu überziehenden Ge6enstände kann in Fortfall konaen. Mit besonderer Vorteil kann die Erfindung für das Aufbringen von Rostschutzaitteln auf Stahlrohre angewandt werden.As a result of the fact that solvent-free, heated to processing temperature Preservatives are used, e.g. higher-consistency waxes, oils or water-soluble ones Varnishes, the invention results in uniform flow on the material surfaces, faster drying times as well as the elimination of systems for afterburning and for Sucking off harmful vapors. The objects to be coated can be preheated in failure konaen. The invention can be particularly advantageous for the application of anti-rust agents can be applied to steel pipes.
