After the oxidation treatment of aluminum profiles, attention should be paid to the defects existing on the surface of the aluminum

In order to make the surface of industrial aluminum produce a hard surface, the manufacturer will oxidize some aluminum workpieces, so that its processing effect can not only improve the performance of aluminum workpieces, but also improve the aesthetics of the workpiece, however, after the oxidation treatment of aluminum, we still need to pay attention to some problems, otherwise, the use of aluminum workpieces is not good, and even lead to early damage to industrial aluminum.

1. Hot water rinsing, hot water eye washing is an aging film, but the water temperature and time should be strictly controlled, the water temperature is too high, the film layer becomes thinner, the color becomes lighter, and similar problems will occur when the treatment time is too long, the appropriate temperature and time are: temperature 40×50°C, time 0.5~1min.

2. Drying, drying is better is natural drying, the industrial aluminum workpiece of barley rinsed with hot water is tilted on the rack, so that the free water on the working surface flows in a straight direction, and the water droplets flowing to the lower corner are sucked away with a towel, and the color of the film dried in this way is not affected, it seems natural.

3. Aging, the aging method can be determined according to the climatic conditions, the sunny summer can be exposed to the sun, the alumina can be baked in the oven in rainy days or winter, the process conditions are: temperature 40×50°C, time 10~15min.

4. Repair of unqualified parts, unqualified conductive oxide film parts should be selected before drying and aging, because it is difficult to remove the film layer after drying and aging, and will affect the surface roughness of the workpiece, for unqualified workpieces, we can take the following simple measures to solve it.

Industrial aluminum.

In fact, it is an abbreviation for thermal insulation aluminum alloy profile, which is composed of aluminum alloy inside and outside the material, and the middle is made of non-metallic insulation materials with low thermal conductivity to form a "thermal bridge" composite material.

There are three production methods for thermal insulation profiles, namely "casting type", "threading type" and "pouring roll integrated type".

Among them, the "pouring roller integrated thermal insulation aluminum alloy profile" has excellent performance, because the production process is very high, and most of the "through-bar thermal insulation aluminum alloy profiles" on the market are "through-strip thermal insulation aluminum alloy profiles".

First, only focus on the price, not the configuration.

When we understand the brand, model, wall thickness, insulation strip, hardware, sealant strip and whether there are additional charges or other wear ......, it is meaningless to compare products of the same brand and model, because the moisture of the aluminum profile is very large, some use brand aluminum profiles, some use miscellaneous brand aluminum profiles, the difference is very large.

Second, over-trust in the "foreign brands" in the market.

At present, the so-called "foreign brand" doors and windows in the broken bridge aluminum market are basically small manufacturers OEM most, the real imported brand of broken bridge aluminum doors and windows in the market is cheaper than yuan / square meter, and those so-called "foreign brand" broken bridge aluminum is mostly priced in -yuan per square meter, through the door and window factory packaging under the foreign name to carry out external publicity, these brand materials look very thick, but the purity and strength of aluminum is not as good as that of domestic big brands, industrial aluminum.
