Fluorocarbon curtain wall aluminum veneer spraying pretreatment process
Technical Field
The invention relates to the technical field of aluminum veneers, in particular to a spraying pretreatment process for aluminum veneers of fluorocarbon curtain walls.
Background
The aluminum veneer for the fluorocarbon curtain wall is a novel curtain wall material which is formed by adopting a high-quality aluminum alloy plate as a base material and then carrying out numerical control bending and other technical forming and spraying fluorocarbon coating on the surface. The fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt mist and various air pollutants, has excellent cold and heat resistance, can resist the irradiation of strong ultraviolet rays, can keep colorfast and not chalking for a long time, and has long service life.
Before the fluorocarbon coating is sprayed on the aluminum plate, the surface of the aluminum plate needs to be subjected to acid pickling treatment to remove impurities and an oxide layer formed on the surface of the aluminum plate. According to the difference of the installation position, the aluminum veneer of the fluorocarbon curtain wall is divided into a square structure and a bevel structure, the process of pickling the aluminum veneer of the square structure is simpler, and the prior pickling process of the bevel aluminum plate has some problems:
(1) at present, when the bevel type aluminum veneer is pickled, the aluminum veneer is usually soaked in pickling solution again, the side wall of the aluminum veneer is washed by a spraying mode, the space of the bevel part of the aluminum veneer is small, and therefore the bevel part is difficult to be sufficiently washed by spraying liquid, and residual impurities still exist on the surface of the aluminum veneer after pickling.
(2) The impurity that drops from the aluminium veneer during pickling will be melted into the pickle to final deposit is in the pickling tank bottom, when needing to clear up these impurities, needs earlier the pickling tank evacuation, demolish some devices again to leave sufficient clearance space, and whole work load is great, consumes time long.
