Good extruded aluminum profiles, the surface corrosion resistance is not strong, must be anodic oxidation surface treatment to increase the corrosion resistance, wear resistance and appearance of the aluminum, in the aluminum profile oxidation process is also a certain amount of detailed flow, the oxidation steps are mainly： 1, Surface pretreatment;Chemical or physical methods are used to clean the surface of the profile, exposing the pure matrix, in order to obtain a complete, compact artificial oxide film.Mirror or matte (matte) surfaces can also be mechanically obtained. 2, Anodic oxidation;After surface pretreatment, under certain technological conditions, the surface of the matrix is anodized to form a compact, porous, strong adsorption AL203 film. 3, the hole sealing;The pores and pores of the porous oxide film formed by anodic oxidation are closed to enhance the anti-pollution, anti-corrosion and anti-wear properties of the oxide film.The oxide film is colorless and transparent. The strong adsorbability of the oxide film before sealing the hole can be used to adsorb and deposit some metal salts in the hole, which can make the profile appearance show many colors other than the natural color (silver white), such as;Black, bronze, gold and stainless steel, etc. Industrial aluminum is a kind of widely used metal building materials products, because of its superior soft texture and easy processing performance, as well as its surface noble metal quality, etc., deeply loved by people.Therefore, only by controlling every detail in the production process of aluminum profile, can the quality of aluminum profile be guaranteed. In fujian, the double constant group, product variety, quality oubiao industrial aluminum and flexible and convenient for fitting, in mechanical manufacturing, factory equipment, industrial production line, factory automation and automated production equipment, and other fields, to bring our customers such as: exhibition frame structure, equipment, machinery casings, machine frame protection device, protective barrier, safety fence, industrial assembly line, aluminum workbench , etc.

Aluminum pallet unique low temperature performance, especially suitable for cold storage and other low temperature use occasions; 3. Light weight, can be transferred manually, effectively reducing the transport weight; 4. Long service life, high recovery value, salvage value up to 30%-50% of the purchase price; 5. Aluminum pallet size is not limited by mold, can be made according to any size requirements; The aluminum pallet designed and produced by Fujian Shuangheng Group is made of aluminum pallet with special section and welded together. The surface of the tray is of a flat structure. All the section incisions are welded with a sealing plate and the inner hollow structure is adopted. Higher strength and impact resistance, greatly reducing bacteria and dirt hiding space, easier cleaning and maintenance.

Aluminium profile basically does not have national standard not standard of say, but China has special industry standard to architectural aluminium profiles, basically make a requirement to the thickness of profile, material. The products produced by every aluminum profile production enterprises are basically the same, but there are differences in the specific structure.But like the more general series, like GB 50, GB 868, GB 90, these are basically the same. 80 series and 60 series refer to the width of the frame of the aluminum alloy profile is 80 mm and 60 mm respectively. According to the processing technology of extruded profiles, they can be divided into oxidation, electrophoresis, electrostatic powder spraying, fluorocarbon spraying, that is to say, different coating methods.At present, 85% of the consumption in the market is electrostatic powder spraying profiles, namely color aluminum profiles.

Industrial aluminum profile in current situation, the demand for both auto, machinery, protection, rail mounting, this will naturally think of the cost and resource use of dual problem, so how to improve the yield of industrial aluminum extrusion become the urgent matter, a lot of measures to improve productivity, this article mainly talk about some relatively more concrete and practical two measures. To increase the output of extrusion products, advanced equipment, high-quality workers, modern scientific management plays a vital role.In our country, the existing more than 2500 industrial aluminum extrusion machine, reach the international level of around 25 sets, only about 1%, aluminum extrusion industry in China is in the stage of structural adjustment, should avoid to low levels of repeat the introduction and development, a transformation of the existing value of industrial aluminum extrusion machine best transformation into modern high levels of industrial aluminum extrusion machine. In general, if there is no unscheduled downtime, then the maximum output is primarily determined by the extrusion speed, which is subject to four factors, three of which are fixed and one of which is variable.The first factor is the extrusion pressure of the industrial aluminum extruder. The extrusion pressure with large extrusion pressure can be extruded smoothly when the billet temperature is low.The second factor is the mold design. The friction between the metal and the mold wall during extrusion can usually increase the temperature of the aluminum alloy passing through by 35 ~ 62℃.The third factor is the characteristics of the aluminum alloy being extruded, which is an uncontrollable factor limiting the extrusion speed. The outlet temperature of the aluminum profile should not exceed 540℃ in general, otherwise, the material surface quality will decline, the mold marks will be significantly aggravated, and even aluminum adhesion, gravure, micro cracks, tear and so on.The last factor is temperature and how much control it has.

The material of aluminum extrusion profile, aluminum itself is a kind of material corrosion resistance is strong, but met after oxygen on the surface of aluminum form 3 oxidation 2 aluminium oxide, so after a long time will slowly lifted his KangFuXing and mo resistance, and aluminum is very sensitive to acid substances, encounter acid can damage the surface of the aluminum group layer, so we need to again after oxidation treatment, add a layer of protective film on the surface. Strengthen KangFuXing surface, aluminum profiles after surface anodized, its corrosion resistance, hardness, wear resistance, insulation and heat resistance were increased significantly.The most anodized metal is aluminum.Anodic oxidation of aluminum tubes is generally carried out in an acidic electrolyte with aluminum as the anode.In electrolysis, the anion of oxygen interacts with aluminum to produce an oxide film.The initial formation of this film is not fine enough, although there is a certain resistance, but the electrolyte of negative oxygen ions can still reach the surface of the aluminum oxide film continues to form.As the film thickness increases, the resistance also increases, thus the electrolytic current decreases.At this point, the outer oxide film in contact with the electrolyte is chemically dissolved.When the rate of formation of oxide on the surface of aluminum gradually balances the rate of chemical dissolution, the maximum thickness of the oxide film under this electrolytic parameter can be achieved.The outer layer of anodic oxidation film of aluminum is porous and easy to absorb dyes and colored materials, so it can be dyed and enhance its decorative effect.The corrosion resistance and wear resistance of oxide film can be further improved after being closed by hot water, high temperature steam or nickel salt.In addition to aluminum, industrial surface anodized metals include magnesium alloy, copper and copper alloy, zinc and zinc alloy, steel, cadmium, tantalum, zirconium and so on.

Solar mounting system is a support designed for placing, installing and fixing solar panels in solar photovoltaic power generation system. At present, common photovoltaic bracket materials in photovoltaic power generation projects include ordinary steel, stainless steel and aluminum profiles, and aluminum profiles are most widely used. Aluminum profile has the advantages of light weight, corrosion resistance, simple structure, easy installation and so on.So many solar pv stands and fasteners now choose aluminum profiles. Industrial aluminum does not need to be welded, directly with the corresponding accessories can be assembled, the period is short, the customer can be assembled on its own.
