PicklageLe picklage consiste à faire absorber à la peau en tripe une quantité importante d'acide, en présence de sel neutre (NaCl) pour réprimer le gonflement que provoquerait l'acidité du milieu.

| Résumé : |
The aim of this study is the development of a salt-free pickling-tanning process and, as a consequence, the reduction of the total conductivity of waste waters. In the first part of the work, a comparative study was carried out to determine the capacity of four commercial products to prevent swelling :
- polyacrylic acid
- naphthol 3-6-disulphonic acid
- p-hydroxydiphenyl sulphonic acid
- a blend of naphthalene and naphthol sulphonic acids (Chemical A) |
