Description

Spritzverfahren für Lacke bzw. Lackfarben Bei dem Verfahren gemäß der Erfinduilg wird durch Erhitzen von Lösungs- bzw. Verdünnungsmitteln in einem besonderen Gefäß kontinuierlich ein Lösungs- bzw. Verdünnungsmitteldampfstrom erzeugt, mit welchem das eigentliche Spritzgut, wie Lack bzw. Lackfarbe, zerstäubt und mit dem Dampfstrom auf den zu lackierenden Gegenstand gespritzt wird. Hier schlägt es sich mit den erkaltenden Dampfteilchen tropfenförmig nieder.Spraying method for lacquers or lacquer paints With the method according to The invention is made by heating solvents or diluents in one a special vessel continuously generates a stream of solvent or diluent vapor, with which the actual spray material, such as paint or paint, is atomized and with the steam is sprayed onto the object to be painted. Here it beats drops down with the cooling vapor particles.

Wesentlich ist, daß die Lösungs- bzw. Verdünnungsmittel für sich erhitzt werden.It is essential that the solvents or diluents are heated by themselves will.

Als Lösungsmittel kommen z. B. Terpentinöl, Leicht- und Schwerbenzine und -benzol in Frage. Außerdem kommen alle an sich bekannten Lösungs- und Verdünnungsmittel für Nitrocelluloselacke in Betracht, wie - z. B. Ester, Äther, Alkohole, Aceton, chlorierte Kohlenwasserstoffe oder Gernische aus diesen Stoffen. Die Entwicklung des Dampfes aus den Lösungs- und Verdunstungsmitteln wird in Apparaten vorgenommen werden, die z. B. durch elektrische Heizwidergtände oder überhitzten Wasserdampf auf Temperaturen über dem Siedepunkt des Löse- oder Verdünnungsmittels gebracht werden. Hierbei kann der Dampfentwickler unmittelbar mit dem Spritzgerät verbunden sein, oder es werden, beispielsweise bei größeren Anlagen, die entwickelten Dämpfe durch erhitzte Leitungen dem Zerstäuber zugeführt.As a solvent, for. B. turpentine oil, light and heavy gasoline and benzene in question. In addition, all known solvents and diluents for nitrocellulose lacquers are suitable, such as - z. B. esters, ethers, alcohols, acetone, chlorinated hydrocarbons or mixtures of these substances. The development of the vapor from the solvents and evaporation agents is carried out in apparatus which, for. B. be brought to temperatures above the boiling point of the solvent or diluent by electrical Heizwidergtände or superheated steam. The vapor generator can be connected directly to the spray device, or, for example in the case of larger systems, the vapors developed are fed to the atomizer through heated lines.

Das Erhitzen der Leitungen, die zweckmäßig isolierte Metallschläuche sind, kann durch die Wärme der 'hindurchtreibenden Lösungsmitteldämpfe erfolgen. Das Abkühlen der Dämpfe wird dadurch vermieden, daß innerhalb der Leitung in Abständen Apparate angebracht sind, die durch elektrische Heizwiderstände erhitzt werden. In diesen Apparaten werden die Dämpfe nachgewärmt. Das letzte Nachwärmen der Dämpfe erfolgt kurz vor deren Eintritt in das Spritzgerät.The heating of the lines, the appropriately insulated metal hoses can be done by the heat of the 'solvent vapors driving through. The cooling of the vapors is avoided by keeping them inside the line at intervals Apparatuses are attached, which are heated by electrical heating resistors. In these devices the vapors are reheated. The final warm-up the vapors occur shortly before they enter the spray device.

Durch das Spritzverfahren gemäß der Er-, findung wird die sonst bei Spritzverfahreh2 nicht vermeidbare Nebelbildung wesentlichverringert.Through the spraying process according to the invention, the otherwise with Spraying process significantly reduces unavoidable mist formation.
