Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] refer to figure 1 :

[0033] (1) Shelving process

[0034] 1. According to the different cross-sections of aluminum alloy profiles, they must not be put on the shelves in the same row. Try to put the same type of material in the same row for each shelf.

[0035] 2. Before putting on the shelves, the conductive edges and corners of the conductive rod must be evenly polished with a file. When moving the conductive rod, use a grinder to grind the contact surface of the conductive beam and the conductive rod. The conductive rod has been used for a long time, and the cross section is too small, so it needs to be replaced. Under normal circumstances, when the ...

Abstract

The invention relates to a technology for producing wood-like aluminium alloy section bar with environmental protection and super weatherability, which comprises the following steps: grounding, removing oil by employing sulfuric acid; performing alkali corrosion by employing NaOH; neutralizing in a neutralization groove, wherein a liquid in the neutralization groove is a mixture of sulfuric acid and nitric acid; performing anodization, wherein an aluminium alloy section bar is introduced in an oxidation, and liquid in the oxidation groove is energized for oxidation; performing electrolytic coloring, wherein the aluminium alloy section bar is introduced in a coloring groove, the coloring groove is energized for coloring; performing electrophoresis; detecting, and pasting the wood grain. The average oxide-film thickness is greater than or equal to 6mum, the average electrophoresis paint film thickness is greater than or equal to 20mum, and average conposite membrane thickness is greater than or equal to 26mum. The product has the advantages of good weatherability and corrosion resistance with 9.8 grade, luster maintenance rate can reach more than 95%, color losing is not generated on surface after weatherability tests on surface, and the wood-like aluminium alloy section bar is suitable for all building door and windows, curtain walls and indoor decoration.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy profile production technology, in particular to an environment-friendly, super-weather-resistant wood-grain imitation aluminum alloy profile production process. Background technique [0002] Due to its high strength and high rigidity, aluminum alloys are widely used in various industries, including mechanical parts, aircraft, automobiles, precision instruments, radio equipment, building shells, machine shells, consumer electronics and household appliances, etc. [0003] Aluminum profiles are aluminum rods that are hot-melted and extruded to obtain aluminum materials with different cross-sectional shapes. In the building decoration and decoration industry, people widely use aluminum profiles to make windows, doors and various partitions. Aluminum profiles are also widely loved by users for their lightness, beauty, and fire resistance. [0004] Conventional electrophoretic imitation wood-gra...
