Whatever method is not manufactured sheets of mirror, very important
preliminary surface. In the ideal case, the surface
sheets before applying the gloss should be chemically pure, monotonous
shade.
Control of the surface quality should be carried out at all stages
the technological process. This is necessary because the production
mirror sheets should be considered as a final operation, so
that is, preceding operations must be common to the whole sheet
products. The presence on the surface of leaves, dirt, cuffs rolled foreign bodies
and even heterogeneity shades requires additional operations,
aimed at the elimination of these defects.
Most effective for surface preparation etching in a solution
alkali. After pickling, the sheet was washed with water and they come in a tank
20% solution of nitric acid, and then finally washed
distilled water or condensation of water vapor and dry.
Additional operations surface preparation sheets before applying
gloss can be avoided if we strictly monitor the quality of surface
the entire process, and the cold rolling of strip
to produce using technology based lubricant lungs
mineral oils, surface-active additives.
In this case, the surface of hot-rolled coils should be evenly matte without a trace.
