Представницькі моделі 3 серії алюмінієвих пластин є 3003, 3004, та 3A21, які також можна назвати антикорозійними алюмінієвими пластинами. 3 Серія алюмінієвих листів широко використовується в ізоляції трубопроводів і промисловості автомобільних паливних баків. 3 алюмінієва пластина серії 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, хороші зварювальні характеристики, and corrosion resistance is slightly stronger than that of series 1. It is a medium-strength aluminum alloy.
3003 і 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 і 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. тому, the packaging and storage requirements of 3003 aluminum coils are relatively strict.
The following describes the anti-oxidation measures of the 3003 алюмінієва котушка:
(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, зварюваність і стійкість до корозії, and is mainly used for work with slightly higher strength requirements than the 1 серії, such as pressure tanks, резервуари для зберігання, thermal insulation materials, механічні частини, automobile and aircraft fuel tanks, тощо. It is commonly used in humid environments such as air conditioners, холодильники, та днища автомобіля. The price is higher than the 1 серії. It is a more commonly used alloy series.
