Abstract:
(EN) A polishing agent, an aluminium alloy piece and a polishing method therefor. The polishing agent is used for the pretreatment of the surface of an aluminium alloy piece, and comprises, on the basis of 50 parts by weight, the following components in parts by weight: 3-20 parts of phosphoric acid, 2-10 parts of hydrofluoric acid, 1-5 parts of nitric acid, 1-5 parts of polyethylene glycol, 0.1-0.5 parts of sodium dodecylbenzenesulfonate and the balance of water. After treatment by means of the described polishing agent, the surface of an aluminium alloy piece becomes clean and shiny. In addition, the whole polishing method is simple and environmentally friendly, has no NO2 escape, is easy to operate, and has low use costs.
(FR) L'invention concerne un agent de polissage, une pièce en alliage d'aluminium et un procédé de polissage associé. L'agent de polissage est utilisé pour le prétraitement de la surface d'une pièce en alliage d'aluminium, et comprend, sur la base de 50 parties en poids, les constituants suivants en parties en poids : de 3 à 20 parties d'acide phosphorique, de 2 à 10 parties d'acide fluorhydrique, de 1 à 5 parties d'acide nitrique, de 1 à 5 parties de glycol polyéthylénique, de 0,1 à 0,5 partie de dodécylbenzènesulfonate, le reste étant de l'eau. Après traitement au moyen de l'agent de polissage décrit, la surface d'une pièce en alliage d'aluminium devient propre et brillante. De plus, l'ensemble du procédé de polissage est simple et respectueux de l'environnement, ne présente aucun dégagement de NO2, est facile à utiliser, et a de faibles coûts d'utilisation.
