"Procédé de désoxydation de-surfaces métalliques oxydées ainsi que de préservation d'oxydation des surfaces ' talliques."
L'invention est basée sur l'observation d'après laquelle on a constaté que des substances colloïdales gon- tenues en proportion de 20 à 60 % environ dans la vase
<Desc/Clms Page number 2>
d'eau salée ou dans la vase d'eau douce et constituées par des composés de silicium non saturée sont douées, à l'état humide naturel ou à l'état sec obtenu en prenant des pré- cautions spéciales, de la propriété soit de désoxyder des surfaces métalliques oxydées,soit de préserver de l'oxy- dation les surfaces métalliques.
Si l'on met par exemple des pièces rouillées de fer ou d'acier en contact intime avec des colloïdes sili- eiques actifs de ce,genre , l'oxygène est enlevé de l'oxyde ferrique qui forme la rouille et le fer réduit constitue de concert avec les composés siliciques une couche protectrice qui adhère avec une ténacité extrême sur la surface su- périeure de la pièce en fer ou en scier et qui empêche une nouvelle formation de rouille. Il en est de même pour d'autres métaux.
Le nouveau procédé consiste à mettre en contact intime des surfaces métalliques oxydées soit avec de la vase brute,soit de préférence avec les substances colloï- dales actives contenues dans la vase brute que l'on peut séparer de celle-ci de diverses manières, par exemple,par mise en suspension-et par séparation subséquente des élé- ments non colloïdaux en essorent ou en laissant déposer.
On effectue cette opération soit en plongeant pendant une certaine durée ces surfaces métalliques dans une suspension de vase ou des éléments colloïdaux séparés de celle-ci que'l'on maintient judicieusement à l'abri de l'air et en mouvement provoqué par agitation , soit en y appliquent comme peinture une couche permanente qui a été faite avec de la
<Desc/Clms Page number 3>
vase ou avec des colloïdes siliciques précipitée de celle- ci et avec un liant approprié, tel que par exemple: - colle, gélatine, caséine, huile siccative ou laque et autres substances semblable - , avec ou sans addition de colo- rants ou de toutes autres matières aptes à servir à titre d'agente préservateurs-de rouille ou de peinture.
En tant que l'on veut ou que l'on doit employer à cet effet soit de la vase sèche, soit des colloïdes secs provement de la vase,l'opération de séchage doit s'effectuer à l'abri de l'air et à température la plus basse possible (40 à 80 C.) car si le séchage s'opère à température supérieure et avec accès d'air, les éléments colloldaux non saturés de la vase passent à l'état amorphe et entrent difficilement en réac- tion et ils perdent ainsi de fagon constante leur puissance réactionelle.
On peut rendre plus-grande encore la puissance réactionelle de ces peintures, couches ou suspensions que l'on emploie pour la désoxydation de surfaces métalliques oxydées, ainsi que pour préserver de la rouille des sur- faces métalliques, en abandonnant-a elles-mêmes avant leur emploi pendant quelques jours à l'état de suspension et à l'abri de.l'air la vase brute ou les colloïdes séparés *de celle-ci; alors les bactéries anaérobiques existantes se multiplient avec une intensité telle qu'elles l'emportent sur les bactéries aérobiques et contribuent ainsi à donner une réduction de la teneur d'oxygène, ainsi qu'une désagra- gation plus forte des parcelles substantielles colloïdales.
On peut encore accélérer ou seconder cette activation artificielle ou cet accroissement de la puissance réaction- nelle des éléments colloldaux de la vase en mettant, dans la suspension, des bouillons de culture de bactéries qui con- vienneht à cet effet et en y ajoutant éventuellement des bouillons de cultures de bactéries anaérobiques.

"A method of deoxidizing oxidized metal surfaces as well as preserving oxidation of metal surfaces."
The invention is based on the observation that it has been found that colloidal substances swelled in a proportion of about 20 to 60% in the silt
<Desc / Clms Page number 2>
of salt water or in the mud of fresh water and consisting of compounds of unsaturated silicon are endowed, in the natural wet state or in the dry state obtained by taking special precautions, of the property either of deoxidize oxidized metal surfaces, or preserve metal surfaces from oxidation.
If, for example, rusted pieces of iron or steel are placed in intimate contact with such active silicic colloids, oxygen is removed from the ferric oxide which forms rust and the reduced iron constitutes together with the silicic compounds a protective layer which adheres with extreme tenacity to the upper surface of the iron or sawn workpiece and which prevents further rust formation. The same is true for other metals.
The new process consists of bringing oxidized metal surfaces into intimate contact either with crude silt, or preferably with the active colloidal substances contained in the crude silt which can be separated therefrom in various ways, for example. for example, by suspending and subsequently separating the non-colloidal elements therefrom or by allowing them to settle.
This operation is carried out either by immersing these metal surfaces for a certain period of time in a slurry suspension or in colloidal elements separated from the latter which are judiciously kept away from the air and in movement caused by agitation, either by applying a permanent coat as paint which has been made with
<Desc / Clms Page number 3>
vase or with silicic colloids precipitated therefrom and with a suitable binder, such as for example: - glue, gelatin, casein, drying oil or lac and other similar substances -, with or without addition of dyes or of all other materials suitable for use as a rust or paint preservative.
As long as one wishes or must use either dry mud or dry colloids from the mud, the drying operation must be carried out in the absence of air and at the lowest possible temperature (40 to 80 C.) because if the drying takes place at a higher temperature and with access to air, the unsaturated colloidal elements of the mud pass to the amorphous state and hardly enter into reaction tion and thus constantly lose their reaction power.
The reaction power of those paints, coats or suspensions, which are employed for the deoxidation of oxidized metal surfaces, as well as for preserving metal surfaces from rust, can be made even greater by leaving them to themselves. before their use for a few days in the state of suspension and sheltered from air, the crude mud or the colloids separated * from it; then the existing anaerobic bacteria multiply with such intensity that they outweigh the aerobic bacteria and thus contribute to give a reduction in the oxygen content, as well as a stronger disintegration of the substantial colloidal particles.
This artificial activation or this increase in the reaction power of the colloidal elements of the mud can be further accelerated or assisted by placing in the suspension suitable bacterial culture broths and possibly adding to it bacteria. broths of anaerobic bacteria cultures.
