  "Procédé de préparation de cire sous forme de poudre, destiné

  
à empêcher l'agglutination de la cire pulvérulente".

  
L'objet de la présente invention est un procédé de préparation de cire sous forme de poudre., destiné à empêcher l'agglutination de la cire pulvérulente. Le procédé est caractérisé en ce qu'à la masse de cire fondue à travailler, ou à la poudre de cire, on ajoute des huiles siccatives, des vernis ou des laques, ou en ce que la poudre de cire est traitée de façon telle, par une solution ou émulsion d'une huile siccative, d'un vernis ou d'une laque, qu'une agglutination de la cire pulvérulente est empêchée complètement ou du moins dans une grande mesure, pendant la fabrication ou pendant la conservation.

  
Grâce au réglage de la température de la cire fondue, de la vitesse d'écoulement dans le gicleur de pulvérisation, de la température de l'air et de la densité de l'air, on peut obtenir

  
de

  
une poudre de cire dont les dimensions/particules sont comprises entre celles de grains de semoule et celles de la poussière la plus fine. Pour éviter une agglutination ou une agglomération

  
des particules de poudre pendant la fabrication ou pendant la conservation de la poudre de cire, on peut employer les procédés suivants:

  
Avant la transformation, on ajoute à la masse de cire fondue des huiles siccatives, des vernis ou des laques solubles, dans le but de recouvrir les particules de cire d'une pellicule protectrice, ce qui a pour effet d'empêcher les particules de s'agglutiner les unes aux autres. Il se forme également une pellicule

  
de protection autour des particules de cire lorsqu'une solution ou une émulsion d'une huile siccative, d'un vernis ou d'une laque est simultanément introduite dans la chambre de pulvérisation, pendant la fabrication de la cire pulvérulente, par le pulvérisateur de liquides. En outre, la poudre de cire peut être introduite dans une solution ou une émulsion, par exemple, d'une huile siccative, d'un vernis, d'une laque ou d'une substance analogue, ce qui provoque la formation d'une pellicule de protection autour des particules de cire, après avoir éloigné le liquide en excès. En saupoudrant la poudre de cire avec une poudre appropriée, par exemple de la poudre de talc,etc., par malaxage ou

  
par introduction de ces poudres dans la chambre de pulvérisation, pendant la fabrication, à l'aide d'un pulvérisateur, toute agglutination de la cire en poudre est également empêchée, ce résultat pouvant être aussi obtenu par le mélange de poudres de cire ayant des propriétés physiques différentes, par exemple une poudre de cire préparée à partir de cire dure et une poudre de cire préparée à partir de cire tendre, et ce pendant ou après

  
la fabrication. 

REVENDICATIONS

  
1. Procédé Pour la préparation de cire sous forme de poudre, destiné à empêcher l'agglutination de la cire pulvérulente, caractérisé en ce qu'on ajoute à la masse de cire fondue ou à la poudre de cire, des huiles siccatives, des vernis ou des laques, ce qui empêche l'agglutination de la cire pulvérulente.



  "Process for preparing wax in powder form, intended

  
preventing clumping of the powdered wax ".

  
The object of the present invention is a process for preparing wax in powder form, intended to prevent the agglutination of the powdered wax. The process is characterized in that drying oils, varnishes or lacquers are added to the mass of molten wax to be worked, or to the wax powder, or in that the wax powder is treated in such a way, by a solution or emulsion of a drying oil, varnish or lacquer, that agglutination of the powdered wax is prevented completely or at least to a great extent, during manufacture or during storage.

  
By adjusting the temperature of the molten wax, the flow rate in the spray nozzle, the air temperature and the air density, it is possible to obtain

  
of

  
a wax powder whose dimensions / particles are between those of semolina grains and those of the finest dust. To avoid agglutination or agglomeration

  
of the powder particles during the manufacture or during the preservation of the wax powder, the following methods can be used:

  
Before processing, drying oils, varnishes or soluble lacquers are added to the melted wax mass with the aim of covering the wax particles with a protective film, which has the effect of preventing the particles from s 'agglutinate to each other. It also forms a film

  
protection around the wax particles when a solution or an emulsion of a drying oil, a varnish or a lacquer is simultaneously introduced into the spray chamber, during the manufacture of the powdered wax, by the sprayer of liquids. Further, the wax powder can be introduced into a solution or emulsion, for example, of a drying oil, varnish, lacquer or the like, which causes the formation of a protective film around the wax particles, after removing the excess liquid. By dusting the wax powder with a suitable powder, for example talcum powder, etc., by kneading or

  
by introducing these powders into the spray chamber, during manufacture, with the aid of a sprayer, any agglutination of the powdered wax is also prevented, this result being also obtainable by the mixing of wax powders having different physical properties, for example wax powder prepared from hard wax and wax powder prepared from soft wax, during or after

  
the making.
