Problems solved by technology

If the pre-treatment is not done well, the rust will continue to spread under the coating, causing the coating to fall off in flakes
The surface that has been carefully cleaned and the workpiece that is generally cleaned (manually with sandpaper or brush) are compared by the exposure method, and the service life can be 4-5 times different.

Abstract

The invention provides a production process capable of improving the toughness of an aluminum profile. The production process comprises the following steps of: performing homogenization treatment on the aluminum profile, further performing solution treatment, and performing water quenching after the solution treatment to get a finished product, wherein the temperature for the solution treatment is 480-520 DEG C and the treatment time is 2-4 hours; clearing a solvent and performing acid cleaning; immersing the aluminum profile in the solvent for cleaning, and cleaning in clear water; selecting a spraying material, preliminarily setting sandblasting pressure as 200-250KPa, setting sandblasting distance as 160-180mm, setting sandblasting time as 8-15s and setting the number of turns of a product as 45-55RPM; repeatedly sandblasting the aluminum profile according to parameters; then performing surface processing on the aluminum profile and receiving the material; and packaging. According to the production process disclosed by the invention, harm to environmental pollution and health of a worker, which is caused by dust, can be greatly improved, and the production process can be directly mounted on a production line so as to save production area and be conducive to turnover of a workpiece.

Description

technical field [0001] The invention relates to a production process for improving the toughness of aluminum profiles. Background technique [0002] At present, energy and environmental protection are the two major issues facing the industry in the world today, and lightweight is an effective way to reduce energy consumption and environmental pollution. Aluminum alloy material has become an ideal material because of its high specific strength, corrosion resistance, good impact resistance, easy surface coloring, good processing formability and high recycling and regeneration. [0003] Before the workpiece is sprayed and sprayed with a protective layer (paint or other anti-corrosion materials), the surface of the workpiece should be carefully treated, which is called pre-treatment. [0004] The quality of the pre-treatment affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating, because the best coating film (layer) adheres to the careful...
