After a long period of using, we will find that interior of aluminum profile is relatively easy to dirty, then it should be cleaned in time to avoid rust, rupture and other problems.

Precautions for cleaning aluminum profiles:

1. It has alkalinity, no long-term contact with the skin

2. Should not be used for painting finishes, polished or electroplating aluminum surfaces and finished finished surfaces of automobiles.

3. Clean old equipment or badly rusted surface should pay attention to check whether there is a leak.

4. After the industrial aluminum profile has been coolly deformed, due to the destruction of the crystal and between the crystals, the lattice has produced distortion and the appearance of the second type of residual stress, so that the plasticity index is sharply reduced, in the limit state may be close to the state of complete brittleness. On the other hand, due to lattice distortion, increased bit misalignment, granular lengthening and substructure, and so on, and its strength index greatly improved, that is, the phenomenon of processing hardening.

The physical and chemical properties of aluminum profiles

1. Density. After cold deformation, the density of aluminum is reduced due to microcracks or macro-industrial aluminum cracks and cracks and other defects in the crystal and between crystals.

2. Resistance. The destruction of intercrystalline matter makes the direct contact of grain, the grain level is ordered, the intercrystalline and the crystal rupture, etc., all have obvious effects on the change of resistance. The first two decrease the resistance with the degree of deformation, which in turn.

3. Chemical stability. After cold deformation, the industrial aluminum profile material can be increased, making its chemical properties more unstable and susceptible to corrosion, especially stress corrosion.
