Des études de terrain et en laboratoire ont permis l'obtention d'excellente performance de traitement de surface par polissage. Avec des taux très importants d'élimination des corps gras, des souillures et des résines naturels et industriels, le décapage s'applique à différents types de métaux et sans rayures (aciers, fontes, bronze, aluminium). Field and laboratory studies have resulted in excellent polishing surface treatment performance. With very high rates of elimination of grease, dirt and natural and industrial resins, stripping applies to different types of metals and without scratches (steel, cast iron, bronze, aluminum).

L'objet de la présente invention est le traitement d'une plaque de cuivre en utilisant une faible quantité de phosphate synthétique. The object of the present invention is the treatment of a copper plate using a small amount of synthetic phosphate.

Le second objectif de cette invention est que le traitement obtenu est efficace. The second objective of this invention is that the treatment obtained is effective.

C'est dans le cadre d'une démarche inventive que l'on a imaginé un procédé de traitement des plaques de cuivre par polissage avec le phosphate synthétique en procédant comme suit : It is within the framework of an inventive step that a method of treating copper plates by polishing with synthetic phosphate was devised by proceeding as follows:

- On sépare des fractions du phosphate utilisé les éléments grossiers contenus dans lesdites phosphates, de manière à obtenir au moins d'une part une partie grossière et d'autre part une partie plus fine qui subira le traitement. - On lave le phosphate à l'eau distillée avant de le filtrer sur une membrane d'un tamis. The coarse elements contained in said phosphates are separated from the fractions of the phosphate used, so as to obtain at least on the one hand a coarse part and on the other hand a finer part which will undergo the treatment. The phosphate is washed with distilled water before filtering it on a membrane of a sieve.

- Une fois séché on l'homogénéise à l'acide sulfurique (H2S04) concentré en chauffant sous une agitation continue ceci ne conduit pas à la calcination mais à préparer une pâte huileuse grisâtre. Once dried, it is homogenized with concentrated sulfuric acid (H 2 SO 4 ) while heating with continuous stirring. This does not lead to calcination but to the preparation of a greyish oily paste.

- On ajoute à la pâte un volume d'eau saumâtre saturée pour préparer la recette finale, on le maintien par une agitation qui diminue la viscosité de la pâte et facilite l'homogénéisation, puis on calcine ledit mélange au four à une température graduée de 100 à 700 °C pendant 4 heures, après le refroidissement, on procède à la partie de formulation qui constitue le principe actif (le phosphate synthétique) et un support constitué de tensio-actifs, de la graisse, un émulsifîant, un conservateur, un abrasif et du parfum A volume of saturated brine water is added to the dough to prepare the final recipe, it is maintained by stirring which reduces the viscosity of the dough and facilitates homogenization, and then said mixture is calcined in the oven at a graduated temperature of 100 to 700 ° C for 4 hours, after cooling, we proceed to the part of the formulation that constitutes the active ingredient (synthetic phosphate) and a carrier consisting of surfactants, fat, an emulsifier, a preservative, a abrasive and perfume

On sépare des fractions du phosphate utilisé les éléments grossiers contenus dans lesdites phosphates, de manière à obtenir au moins d'une part une partie grossière et d'autre part une partie plus fine qui subira le traitement. Fractions of the phosphate used are separated from the coarse elements contained in said phosphates, so as to obtain at least on the one hand a coarse part and on the other hand a finer part which will undergo the treatment.
