The main body of the product is made of high-quality aluminum alloy profile, with reasonable design, sturdy structure, beautiful appearance, etc. It is widely used in the industries of instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and so on, and it is the ideal case for high-grade instruments and meters.
Aluminum alloy tool box maintenance
1, it is recommended that each time before the storage of leather products, it should be dust to do cleaning. General leather products is best to first on the leather maintenance oil, the first oil will be wiped on a clean cotton cloth, and then evenly wipe the surface, to avoid the oil will be applied directly to the surface to avoid damage to the leather parts.
2, storage leather products cabinet must be kept ventilated. Leather's own natural oils will be gradually reduced with time or use too many times, so even if it is a very high-level leather parts also need to do regular maintenance.
3, aluminum alloy box is easy to oxidation, should pay attention to every once in a while to clean, pay attention to anti-fouling.
Maintenance methods of other materials luggage
Canvas, nylon, EVA and other materials box surface cleaning, you can use a wet cloth or viscose roller brush to clean the surface of the dust. Remove the more serious stains, you can use a wet cloth or soft brush dipped in neutral detergent scrub. Inside a suitcase that has been stored for a long time, it is important to keep it in a dry state to prevent mold and odors from developing inside the box.
If you use a damp cloth to clean the inside of your suitcase, it is important to leave it to air dry before closing the lid. Don't use the suitcase as a storage box, storing too much clothing will make the suitcase roller or foot of the long-term overload pressure and deformation. Inside the box clothing straps, dividers should be kept in a relaxed state, elastic band will lose its elasticity if stretched tight for a long time.
Aluminum box aluminum alloy toolbox welding
(1) Selection of wire
General selection of 301 pure aluminum wire and 311 aluminum silicon wire.
(2) Selection of welding methods and parameters
Generally carried out by the left welding method, the torch and the workpiece at an angle of 60 °. Welding thickness of 15mm or more, the right welding method, the torch and the workpiece into a 90 ° angle.
(3) pre-welding preparation
using chemical or mechanical methods, strictly clean up the surface oxide film on both sides of the weld bevel.
Mechanical cleaning can be used wind or electric milling cutter, but also can be used scraper, file and other tools, for the thinner oxide film can also be used to remove the oxide film 0.25mm copper wire brush grinding.
Clean up immediately after welding, if placed more than 4h, should be re-cleaned.
(4) aluminum box in aluminum and aluminum alloy material characteristics
Aluminum is a silver-white light metal, has good plasticity, high electrical and thermal conductivity, but also has the ability to resist oxidation and corrosion. Aluminum is highly susceptible to oxidation to produce aluminum trioxide film, in the weld is prone to inclusions, thus destroying the continuity and uniformity of the metal, reducing its mechanical properties and corrosion resistance.
(5) aluminum and aluminum alloy materials in the aluminum box aluminum alloy materials welding difficulties
Extremely easy to oxidize. In the air, aluminum is easy to combine with oxidation, generating dense aluminum oxide film (thickness of about 0.1-0.2μm), high melting point (about 2050 ℃), far more than the melting point of aluminum and aluminum alloy (about 600 ℃ or so). Alumina density 3.95-4.10g/cm3, about 1.4 times that of aluminum, the surface of the alumina film is easy to adsorb water, welding, it impedes the fusion of the basic metal, it is very easy to form pores, slag, not fused and other defects, resulting in a decline in the performance of the weld.
