Be familiar with the five problems that affect the quality of
aluminum
Aluminum, which has been a major consumer in hubei building
materials market, is much larger than the consumption ratio of
plastic steel. But as a result of aluminous material does not
belong to public channels for consumer products, at a place of
building materials supermarket generally don't have to sell, nature
is the lack of attention, once appear quality problem, consumers
could not say why, to solve the problem, natural hard.
Quality inspection report
The aluminum quality problem is outstanding
Municipal bureau of quality and technical supervision was once a
sampling of aluminium profile, find the main quality problem is
stress bar wall thickness of the section size, mechanical
properties such as tensile strength, elongation, chromium,
manganese, magnesium, copper, silicon, titanium, iron, zinc and
other materials of chemical component content, the average film
thickness, individual local film thickness thickness of oxide film
and so on.
From the results of the spot check, there are some key quality
problems, such as excessive amount of chemical content, the
difference between the thickness of the oxide film and the standard
requirements, and the failure of the wall thickness of the stress
bar.
The expert thinks, what the chemical elements such as chromium,
manganese, magnesium and copper content exceeds bid, on the
corrosion resistance of aluminum alloy profile, machining, welding
and so on all have great influence, directly affect the performance
of aluminum alloy doors and Windows, sliding door and other
products.
With thin thickness of oxide film, will directly affect the
corrosion resistance of aluminum products, over time the product
surface will change color, a little encounter with acid and
alkaline substances will corrode, seriously affect adornment
effect, affect the mood that occupy the home; Stress bar wall
thickness is unqualified, to cause a decline in product of the
force strength, easy to deformation, make the doors and Windows,
sliding door and other products are difficult to run with
"carefree", can appear even safety accidents.
