2. the surperficial grease removal of aluminium section bar: degreasing in advance, degreasing, washing;
3. the electrophoretic process of aluminium section bar: at first in the solution tank of 20～25 ℃ of TRs, solids content is in 15～17% scopes, then under the condition of pH value 6.0～6.3, in 100～160V voltage range, carries out electrophoresis; And electrophoresis time is 3～4min, washes with the clear water under the normal temperature; Oven dry, rewinding;
4. pack.
Further, the production technique of above-mentioned raising aluminium section bar intensity, wherein, extrusion temperature is 350 ℃, obtains aluminium section bar; Aluminium section bar after the extruding was placed 10 days after 400 ℃/1h solid solution naturally.
Further, the production technique of above-mentioned raising aluminium section bar intensity, wherein, the electrophoretic process of step aluminium section bar is 3. at first carried out the electrophoresis time of 4min in solution under 25 ℃, 150V, solids content are the condition of 16% pH value 6.1; Use clear water at normal temperatures to clean then; Oven dry, rewinding again.
The substantive distinguishing features of technical scheme of the present invention is mainly reflected in progressive:
Improve the intensity and the plasticity of material through annealing and extruding, the high low potential thickness of electrophoresis layer evenly, can cover the shelter fully, and adhesive ability strong, be not easy to come off, rotproofness is strong and open and flat smooth, compliance with environmental protection requirements more.
Embodiment
The technological process of production that the present invention improves aluminium section bar intensity is: at first aluminium alloy cast ingot is carried out homogenizing annealing, be about to aluminium alloy cast ingot and be raised to 450～480 ℃, insulation 12～24h, air cooling then from room temperature with the temperature rise rate of 45～60 ℃/h; After the ingot homogenization annealing, push, extrusion temperature is 300～390 ℃, obtains aluminium section bar; Aluminium section bar after the extruding is placed 80～90h naturally after 350～400 ℃/1h solid solution; Follow preparatory degreasing, degreasing, washing; Then in the solution tank of 20～25 ℃ of TRs, solids content is in 15～17% scopes, then under the condition of pH value 6.0～6.3, in 100～160V voltage range, carries out electrophoresis; And electrophoresis time is 3～4min, washes with the clear water under the normal temperature; Oven dry, rewinding; Packing.
