ce sunt benzi de aluminiu?
Materia primă a benzii de aluminiu este aluminiu pur sau aliaj de aluminiu bobina de aluminiu turnată și bobina de aluminiu laminată la cald, rulat în bobină subțire de aluminiu de diferite grosimi și lățimi cu o mașină de laminare la rece, și apoi tăiați în bandă de aluminiu de lățimi diferite.

Aluminum profiles in the color before, the first oxidation, extrusion good aluminum alloy profile, its surface corrosion resistance is not strong, must be anodized to increase the corrosion resistance of aluminum, wear resistance and appearance of beauty.
The main process is as follows:
(1) Pretratarea suprafeței: chemical or physical methods are used to clean the surface of the profile, exposing the pure matrix, pentru a se obţine un film de oxid artificial complet şi dens. Specular sau mat (mat) suprafetele pot fi obtinute si mecanic.
(2) Oxidare anodica: under certain technological conditions, anodic oxidation takes place on the surface of the pretreated profile, and a layer of dense, porous and strong adsorption AL203 film is generated.
(3) sealing: the pores of the porous oxide film generated after anodic oxidation are closed, astfel încât anti-poluarea, anti-corrosion and wear resistance of the oxide film are enhanced.
Filmul de oxid este incolor și transparent, using the strong adsorption of the oxide film before sealing, some metal salt is adsorbed and deposited in the film hole, which can make the profile appearance appear natural (alb argintiu) outside many colors, ca: negru, bronz, gold and stainless steel color.
The current aluminum alloy profile coloring methods are: anodic oxidation, electrophoresis, pulverizare, and wood grain transfer printing four. Because of its excellent anodic oxidation characteristics, most of the black aluminum strip anodic oxidation process for processing.

Aluminum strip processing technology.
An aluminum strip is a deep - processing product made by cutting aluminum coil. Este o materie primă importantă în industrie.
According to the different alloying elements contained in the aluminum strip, aluminum strip and aluminum plate are also divided into 8 serie. in orice caz, seriile utilizate frecvent sunt 1000,3000,5000 și 8000 serie.
În funcție de starea de recoacere diferită a benzii de aluminiu, the aluminum strip can be divided into full soft (O stare), pe jumătate tare (H24) și plin de greu (H18). The most commonly used should be the full soft series, as the O type is easier to stretch and bend.
The main processing equipment of aluminum strips is the cutting device, which can be divided into the required length and width according to the need.
Around the world, electronic products no longer rely solely on copper tape for raw materials. As the electrical conductivity of aluminum is only lower than that of copper, the substitution of aluminum strip for the copper strip is becoming a worldwide trend.
