Processus operating conditionibus metallum etching

Metallum etchingEst clavem ad exemplar ornamentum processus of metallum plate fingunt. Ad obtinendum exemplar uber cum patet plagas et fortis decorateness, operam esse solvit condiciones etching processus. Maxime temperatus etching solutio et etching est. A levius altior temperatus solution potest crescere rate of metallum dissolution, id est, rate of etching et breviare tempus requiritur ad etching. Sed etching solutio plerumque fortis acidum. Fortis acidum mordendo magno temperaturis facile praesidio. The coating or corrosion-resistant ink softens or even dissolves, so that the adhesion of the corrosion-resistant layer of the non-etched part of the metal is reduced, which causes the corrosion-resistant coating at the junction of etching and non-etching to fall off or melt, which makes the etching pattern blurred and distorted, affecting the pattern Because of its beautiful appearance and decorative effect, the temperature should not excedunt XLV ° c.
Similarly, if the etching time is too long, especially when the temperature of the etching solution is high, the immersion time of the corrosion-resistant ink or protective coating is too long, it will also have the above-mentioned side effects and adverse consequences, so the time control should also be appropriate , Can not be soaked for too long, generally should not exceed 20-25min.
