 Commonly used aluminum introduction

　　1, electrophoresis aluminum:

　　1. Strong corrosion resistance: the surface can KangFuXing extremely high, can effectively prevent the acid, alkali, salt erosion. Is the health of the best breed build mortar corrosion.

　　2. Satisfactory performance life, even in harsh. A harsh environment decoration use, also can ensure that more than 50 years life not corrosion. Not aging. Don't fade. Don't fall off.

　　3. Feel smooth delicate, bright appearance. Gorgeous., a variety of colors to choose from.

　　4. Film high hardness. Resistant to 3 H above aluminum pen hardness carved picture.

　　2, the oxidation aluminum:

The base material is used as an anode, in electrolyte of electrolysis, artificially in the substrate surface to form a layer of a protective oxide film and forming aluminum oxide

　　Aluminum oxide main features:

　　1, has the very strong abrasion resistance, resistance to wait, corrosion resistance.

　　2, can be in substrate surface to form a variety of colour, maximum limit for your requirements.

　　3, hardness is strong, suitable for all kinds of construction, industrial material production.

　　Rare earth foam aluminum:

　　Metallic foam is a physical function and structure of the integration of new engineering materials. It has the manifold excellent physical properties in the sound attenuation, shock absorption, separation engineering, and catalytic carrier, shielding protection and absorbing buffer, and other fields have gained wide application. Among them, made of aluminum alloy with rare earth foam aluminum, is also considered to be a great promise for future cars, ships and other transportation tools of good material.

　　According to information, preparation of metal froth roughly: powder metallurgy method and can be divided into loose sintering and reaction sintering two; Seepage law; Sintering dissolved method; Melt foaming method; Eutectic directional coagulation method, etc. In many of these preparation methods, melt foaming method because of its production process relatively simple, low cost, and therefore the most has the prospect of large-scale industrialization. At present Japan's market supply of metal foam is mainly by melt foaming method of a piece of foam aluminum production.

　　The technical difficulties of the melt foaming method is: control of the melt viscosity; Choose appropriate metal foaming agent. Usually the melt viscosity some requirements, at the same time requirements in metal melting point near the foaming agent can quickly blister.

　　Process is divided into two parts: 1, the development of rare earth alloy;2, rare earth foam aluminum alloy preparation.

　　The development of rare earth alloy can not only improve the strength of the alloy, still can reduce the alloy melting temperature, be helpful for preparation intensity of rare earth foam aluminum alloy. In certain alloy viscosity, with appropriate foaming agent equably dispersed to melt in foam, preparation is the key technology of foam metal.0.1%～0.7%。In the rare earth of rare earth alloy additive, rare earth content from 0.1% to 0.7%.

　　The legal system of the melt foam for rare earth foam aluminum alloy, aluminum alloy as matrix with metal, in molten state and prepared by rare earth additive is melting, get rare earth aluminum alloy melt, then add the metal viscous agent and foaming agent, in the rare earth foam aluminum alloy pool in foam reaction, forming obtaining rare earth foam aluminum alloy.

　　4,Architectural aluminium:　　

　　The made of aluminum and Aluminum alloy ,and the material of the system construction products. Usually is first processed into casting products, forgings and foil, board, belt, tubes, rods, profile, then the cold bending, saw cutting, drilling, assembly, coloring process such as and manufactured.

　　But add a little one or several alloy elements, such as magnesium and silicon, manganese, copper, zinc, iron, chromium, titanium, can get with different properties of aluminum alloy. Aluminum alloy cold and heat treatment is it, further strengthened and hardening, the tensile strength greatly increased.

　　Aluminum is 1.67 volts standard potential, chemical properties very lively, easy and the oxygen in air function and form a layer of solid density oxidation film, so in ordinary air and clean water, aluminum has good corrosion resistance. But with steel or other metal material contact can produce the electrochemical corrosion, in damp environment and concrete, cement mortar, such as lime alkaline material can produce the contact corrosion, and timber, soil and other contact when also can produce corrosion. So, need to undertake proper anticorrosive processing.

　　Production method according to the production of aluminium alloy in different ways, aluminum alloy and aluminum alloy casting deformation are divided into two categories. Building on general use of the deformation of aluminum alloy, to rolling into boards, foils, strip, squeeze into rods, tubes or all kinds of complex shapes of profile. According to the deformation properties and USES aluminium alloy is different, divided into stainless aluminum alloy, hard aluminum, super hard aluminum and special aluminum, etc. Building in general use of the industrial pure aluminum (L1 ~ L1), rust aluminum alloy (LF2, LF21, etc) and forging aluminum (LD2), etc.

　　Features and use the biggest characteristic of aluminum and aluminum alloy, the first is the density of about a third of the steel, and than strength limits and proportion to the ratio of the) may reach or exceed structural steel. Second, aluminum and aluminum alloy easily processed into various shapes, can adapt to all kinds of connection technique, thus for building structure is the most economic and reasonable section provides favorable conditions form. So, not only can greatly reduce the aluminum alloy of the weight of the building, saving material, and still can reduce the transportation and installation of the component workload, speed up the construction progress. The zones and traffic for the inconvenience of the mountainous area and the remote areas, its economic effect more significant. Aluminum and aluminum alloy colour and lustre is beautiful, corrosion resistance, light and heat of the dependence of the high, and the absorption performance is good, through the chemical and electrochemical method can obtain a variety of different colors. So aluminum widely used in industrial and civil architecture roofing, metope, doors and Windows, skeleton, &exterior decorative, ceiling, condole top, railing armrest, indoor furniture, store, and construction of the container with templates, etc.

　　Construction is the three main market aluminum one of the total output around 20% of aluminum used for building, some developed countries of the construction industry, with the amount of its total production of aluminum has 30%. In recent years, the construction of aluminum products constantly updated, color aluminum plate, compound aluminum plate, compound window frame, aluminum alloy template construction products such as the application of novel in increases year by year. China has set up a file in the industrial and civil building applications in the production of aluminium alloy roofing, metope, door to wait, and gradually spread inside and outside decoration, construction use templates, etc, has achieved good results.

Aluminum welding standard

　　Aluminum welding method

　　Almost all kinds of welding method can be used for welding aluminum and aluminum alloy, aluminum and aluminum alloy to all sorts of but welding method of adaptability of different, all kinds of welding methods have their applications. QiHan and electrode arc welding method, the equipment is simple, the operation is convenient. QiHan can be used for welding quality requirements are high aluminum plate and repair welding of castings. Electrode arc welding can be used to repair welding of aluminum alloy castings. Inert gas shielded welding (TIG or MIG) method is the most widely used aluminum and aluminum alloy welding method. Aluminum and aluminum alloy plate can use tungsten extremely exchange argon arc welding or tungsten very pulse argon arc welding. Aluminum and aluminum alloy plate can use tungsten extremely helium, argon arc welding helium mixed tungsten extremely gas shielded welding, melt a gas shielded welding, pulse melting extremely gas shielded welding. Melting extremely gas shielded welding, pulse melting extremely gas shielded welding used more and more widely (argon or argon/helium fuel mixture)

　Welding preparation

　　1, before welding cleaning: aluminum and aluminum alloy welding, should be strictly clear before welding workpiece HanKou and welding wire surface oxidation film and oil;

　　1) chemical cleaning chemical cleaning high efficiency, stable quality, YuQingLi welding wire is not big, batch production and size of workpiece. Usable dip method and scrubbing of the two.。Available acetone, gasoline, kerosene and organic solvent oil to the surface, with 40 ℃ ~ 70 ℃ of 5% ~ 10% NaOH solution soda-wash 3 min ~ 7 min (pure aluminum for a long time but not more than 20 min), the current wash them, then use room temperature to 60 ℃ of 30% HNO3 pickling solution 1 min ~ 3 min, rinse flow, air dry or dry at low temperature.

　　2) mechanical cleaning: in big size of workpiece, produce the period is longer, multilayer welding or chemical cleaning and contamination, often by mechanical cleaning. Use first acetone, petrol wipe the surface in order to try organic solvent oil removal, then directly with diameter of 0.15 mm to 0.2 mm copper wire brush or stainless steel wire brush brush, brush to show metal luster so far. Should not be commonly use the grinding wheel or ordinary sand paper burnish, in order to avoid the sand in the metal surface, welded into molten pool produce defects such as slag. In addition, file scraper can also be used for welding surface cleaning, etc.

　　After cleaning up as long time storage (if more than 24 h) shall be to deal with.

　　2, pad: aluminum alloy in high temperature strength is very low, liquid aluminum flow performance is good, in welding weld metal easy to produce up phenomenon.In order to guarantee of penetration and from collapse, welding often in clear and hold to molten pool and the nearby metals. Pad can use graphite plate, stainless steel plate, carbon steel, copper or tongbang, etc. Plate surface open a round HuXingCao, in order to ensure that the weld opposite to shape. Also can not add one formation welding pad, but asked for a skilled or take welding of electric arc welding process energy automatic feedback control and other advanced strict process measures.

　　3 before welding, preheat: thin, small aluminum a generally do not preheating, 10 ~ 15 mm mm thickness can be when before welding preheating, according to different types of aluminum alloy preheating temperature can be for 100 ℃ ~ 200 ℃, can use oxygen, acetylene flame electric furnace or a blowtorch and heating. Preheat can make the welding deformation, reduce the stomata reduce defects.

　　Welding post-processing

　　(1) after welding seam and stay in the remaining near flux and welding slag will destroy aluminum surface passivation membrane, and sometimes corrosion aluminum parts, should be clean. Simple shape, general workpiece can request with hot water or steam blow brush scouring simple method to clear. Demand is high and complex shape of aluminum parts, in hot water after washing hair brush with hard, in 60 ℃ ~ 80 again ℃ or so, density is 2% ~ 3% of chromic acid aqueous or potessium dichromate solution dip 5 min ~ 10 min, and hard brush brush, and then in hot water washing scour, use the oven drying, or with hot air blow dry, can also be natural drying.

　　 (2) after welding aluminum containers after welding heat treatment usually does not require the heat treatment.

Aluminium recycling

Aluminum is the most important one of non-ferrous metal varieties. Since it has good characteristics (density is small, plastic and forming performance is good) and easy to recycle, pure aluminum and aluminum alloy has become an important basic materials home appliance. Widely used in home appliances, electric heat a component such as a FanZao of. The recycled waste mixed aluminum non-ferrous metal recycling has become the most important part of its energy consumption, regeneration cost than aluminium production much lower (about 10%).

Truss "truss" word read "heng", because "truss" word use less, as to be read as "hang" (do), therefore, "line frame" hence the name. By rod a project by welding, riveting or bolt connection and into structures, called "truss".

Truss engineering requirement: the enough strength-not fracturing or plastic deformation; The stiffness of the enough--not happen too much elastic deformation; The stability of the enough--not happen for balance form and lead to sudden change of the collapse of the; Good dynamic characteristics-vibrate resistance.

    Truss design requirements: to have to meet the requirements of stem a; To have good fittings, including rivet, pin and weld connection. These involving truss type, stem a size and material, but the first is the statics analysis.
