Reprezentatywne modele 3 seria płyt aluminiowych Czy 3003, 3004, i 3A21, które można również nazwać antykorozyjnymi płytami aluminiowymi. 3 blachy aluminiowe serii są szeroko stosowane w przemyśle izolacji rurociągów i samochodowych zbiorników paliwa. 3 płyta aluminiowa serii is a commonly used type of alloy aluminum plate. It is an aluminum alloy with manganese as the main alloy element, which cannot be strengthened by heat treatment; it has good plasticity, dobra wydajność spawania, and corrosion resistance is slightly stronger than that of series 1. It is a medium-strength aluminum alloy.
3003 I 3004 series are both aluminum-manganese alloys, which are the most widely used rust-proof aluminum. Now most of them are in the form of sheets and coils. There are many 3003 I 3004 aluminum coils for ordinary pipeline insulation and anti-corrosion, and the thickness Most of them are 0.4-1.2mm, and the width is 1000-1220mm. Because they are delivered in rolls, they are easily oxidized by water during transportation and storage. Dlatego, the packaging and storage requirements of 3003 aluminum coils are relatively strict.
The following describes the anti-oxidation measures of the 3003 cewka aluminiowa:
(1) Strengthen the management of air drying to ensure that there is no water in the compressed air.
(2) Strengthen the management of rolling oil, and control its water content below 0.04%.
(3) The packaging of aluminum foil rolls should be sealed, and an appropriate amount of desiccant should be placed in each roll.
(4) The humidity of the wooden shaft and box board of the packing box is not more than 18%, and the temperature of the packaging aluminum coil is not more than 45 ℃.
(5) When transporting from the low temperature area to the area with high temperature and high humidity, do not open the sealed package immediately.
(6) Aluminum coils should not be placed in places where there is rain or snow on the roof of workshops and warehouses.
The 3 series aluminum plate has good formability, spawalność i odporność na korozję, and is mainly used for work with slightly higher strength requirements than the 1 seria, such as pressure tanks, zbiorniki magazynowe, thermal insulation materials, części mechaniczne, automobile and aircraft fuel tanks, itp. It is commonly used in humid environments such as air conditioners, lodówki, i podwozia samochodów. The price is higher than the 1 seria. It is a more commonly used alloy series.
