The mirror aluminum sheet1.Pure aluminum platePure aluminum plate series common code has 1050, 1070, 1085.Among all aluminum plate series, pure aluminum plate series belongs to a series with the most aluminum content.Purity can be more than 99.00%.As there are no other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in the conventional industry.The majority of the 1050 and 1070 series are in circulation.2.Alloy aluminum plate5××× series alloy aluminum plate: represents 5005 aluminum plate, 5657 aluminum plate series.5××× series aluminum plate belongs to the commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%.It can also be called aluminum magnesium alloy.The main features are low density, high tensile strength and high elongation.The weight of al-Mg alloy is lower than other series in the same area, so it is often used in aviation, such as aircraft fuel tank.It is also widely used in conventional industries.The processing technology is continuous casting and rolling, which belongs to hot rolled aluminum plate series, so it can be further processed by oxidation.In China, the 5××× series aluminum plate is one of the more mature aluminum plate series.5××× series alloy aluminum plate has a good mirror effect.Distinguish between aluminum sheet editorsMirror mirror aluminum board is divided into many kinds, grade from low to high, including film mirror aluminum, domestic polished mirror aluminum, imported polished mirror aluminum, imported oxidized mirror aluminum, and super mirror aluminum plate.According to the characteristics and positioning of your products to choose suitable for your reflector, if you want to do high-end quality products, then choose imported mirror, low-end, choose domestic.The feature of domestic mirror is that the surface is not protected, the mirror rate will change with time, the price is cheap;The characteristics of imported products are stable reflectivity, 86% ordinary mirror and 95% super mirror, the price is a little more expensive.The best mirrors are German and Italian. Japanese mirrors are non-oxidized and are standard sheet material with high wear and tear, but their unique textured effect is favored by shell manufacturers of electronic products.Simple test methods:After tearing off the protective film, touch the mirror surface with your finger. The sweat stains on your finger will remain on the mirror surface, but after wiping it with dry cloth or paper towel, the fingerprint will be wiped clean without leaving any trace.Domestic mirror aluminum plate is different, leaving the finger will be wiped more dirty, finally unable to restore the mirror effect.There are other ways to test:Hold a small aluminum plate to your ear and bend it quickly. If a slight tearing sound can be heard, it is proved to be imported aluminum oxide plate, and vice versa, it is the ordinary polished plate made in China.The oxide film on the surface of the imported aluminum mirror is similar to corundum. Due to the difference in structure between the aluminum and the oxide film, the oxide film will burst and make a slight tearing sound when it is bent.
Decorative aluminum plate related knowledgeI. According to different patterns of aluminum plate, it can be divided into:1. Compass aluminum alloy decorative pattern plate: non-slip aluminum plate, which has the same effect as five ribs, but is not often used.2. Orange peel aluminum alloy decorative pattern plate is divided into: classic orange peel decorative pattern aluminum plate, variable orange peel decorative pattern aluminum plate (also known as insect seed grain).Its surface presents a pattern similar to orange peel, so it can also be called orange peel pattern aluminum plate.It is a series of decorative pattern products commonly used in refrigerators, air conditioners and packaging.3. Five ribs aluminum alloy decorative plates: five ribs non-slip aluminum plates become willowleaf-shaped decorative plates, and aluminum alloy decorative plates.It is widely used in the design of building (floor) platform and so on.Since the pattern on the surface of aluminum plate is arranged in relative parallel in accordance with five concave and convex patterns, and each pattern has an Angle of 60-80 degrees between it and other patterns, this pattern has excellent anti-skid performance.This kind of aluminum plate is usually used as skid proof in China. It has good skid proof effect and is cheap.4. Lentil-shaped aluminum plate is a common type of anti-skid aluminum plate, with good anti-skid effect. It is mainly used in the aspects of anti-skid car, platform, cold storage floor, workshop floor and elevator.5, the spherical pattern aluminum plate can also be called semicircular pattern aluminum plate, the surface shows a small spherical pattern, like a small pearl, so this aluminum plate can become a pearl pattern aluminum plate.Mainly used in outer packing.The appearance is quite beautiful, because of the special pattern, the strength of this aluminum plate is much higher than other pattern series.6, other aluminum decorative pattern material: wavy pattern material, water ripple aluminum decorative pattern plate, corrugated pattern aluminum plate (also can be a aluminum watts), the cane makes up grain pattern aluminum plate, three-dimensional triangular aluminum decorative pattern plate, aluminum plate strip decorative pattern, cobble aluminum decorative pattern plate, aluminum decorative pattern plate, triangle strip pattern aluminum plate, the butterfly pattern aluminum plate etc.7. Rhombus aluminum alloy plate: packing pipe or outer packing is commonly used.Decorative aluminum plates are widely used in furniture: refrigerators, air conditioners, carriages, platforms, packaging pipes, screen frames, various hanging beams, table feet, decorative bars, handle handles, wire slots and covers, chair pipes, etc.According to the different patterns of aluminum plate alloy can be divided into:1, aluminum sheet metal decorative pattern: in 3003 as the main raw material processing and become, this also known as antirust aluminum plate, aluminum sheet strength slightly higher than that of common sheet aluminum decorative pattern, have certain rust resistance, but the hardness and corrosion resistance of less than 5000 series of decorative pattern plate, so the product application in the antirust of request is not strict, such as freight trains, floor in refrigerator.2. Aluminum-magnesium alloy plate: made of 5000 series aluminum plates such as 5052 or 5083 as raw materials, with good corrosivity, hardness and anti-rust properties.It is usually used in special places, such as ships and car lamps in humid environment. This kind of aluminum plate has high hardness and certain load-bearing capacity.3. Ordinary aluminum alloy decorative pattern plate: the aluminum alloy decorative pattern plate made of 1060 aluminum plate as the substrate can adapt to the ordinary environment and the price is low.Usually cold storage, floor, outer packing more use this pattern aluminum plate.
"Aluminum oxide plate drawing wire" drawing wire aluminum plate early cleaning should do?Many of the metal cases we see today use brushed aluminum.A lot of details need to be paid attention to in the process of drawing aluminum plate. In order to ensure the smooth work in the later period, a preliminary cleaning should be carried out before the drawing process of drawing aluminum plate.So, how should the early cleaning of brushed aluminum plate process be done?Brushed aluminum plate1. Mechanical cleaningWhen the workpiece size is large, the production cycle is long, and the multi-layer or chemical cleaning is stained, mechanical cleaning is often used.First with acetone, gasoline and other organic solvents to wipe the surface in order to remove oil, then directly with a diameter of 0.15mm ~ 0.2mm copper wire brush or stainless steel wire brush, brush until the metal shine.Generally, grinding with grinding wheel or ordinary sandpaper is not recommended, so as to avoid sand particles remaining on the metal surface, and slag clamping and other defects will occur when the wire drawing process is carried out.In addition, scraper, file can also be used to clean the surface to be welded.After the workpiece and process are cleaned and cleaned, the oxide film will be generated again in the storage process. Especially in the humid environment, the oxide film will grow faster in the environment polluted by acid, alkali and other vapors.Therefore, the workpiece and wire drawing storage time after cleaning and cleaning to wire drawing should be shortened as far as possible. In the case of humid climate, wire drawing should generally be done within 4h after cleaning.After cleaning, if the storage time is too long (such as more than 24h), it should be handled again.2. Chemical cleaningHigh chemical cleaning efficiency, stable quality, wire drawing process is suitable for cleaning small size, batch production of the workpiece.Can use dip to wash method and scrub method two kinds.Remove oil from the surface with acetone, gasoline, kerosene and other organic solvents, wash with 5% ~ 10%NaOH solution at 40 ° C ~ 70 ° C for 3min ~ 7min(pure aluminum time is a little longer but not more than 20min), then rinse with flowing water, and pickling with 30%HNO3 solution at room temperature to 60 ° C for 1min ~ 3min, then rinse with flowing water and air dry or dry at low temperature.The above is the preliminary cleaning method for the process of drawing aluminum plate. Only after these steps are completed can the process of drawing aluminum plate be better and we can get the final product.
Defects and countermeasures of chemical polishing of "sandblasted aluminum oxide plate" anodic aluminum oxide plateAfter chemical polishing, aluminum and aluminum alloy parts are anodized to obtain a clean, bright and transparent oxide film.A variety of brightly colored surfaces can be obtained after dyeing.There may be some defects in the chemical polishing of anodized aluminum plates.Then, what are the defects and countermeasures of chemical polishing of anodized aluminum plate?Shenzhen Wanxing Aluminum technical personnel for your answer:Anodized aluminum plate1. Low brightness:The reason why the brightness does not reach the expected target can be analyzed from two aspects: the production process of special aluminum and the chemical polishing process.It is recommended to produce special aluminum ingots with purity of 99.70% or above.The quality control in aluminum processing lays a foundation for chemical polishing to obtain high brightness surface.After chemical polishing, it has a high gloss.The lack of nitric acid content in the bath solution will lead to insufficient surface brightness. Too much copper may be attached to the surface, and too much nitric acid content will form colorful iris on the surface of aluminum, which will make the surface obscure or opaque, and also lead to insufficient brightness.Chemical polishing time is not enough, temperature is not enough, stirring is not enough, tank aging will also make the chemical polishing surface brightness is not enough.The relative density of the tank liquid is relatively high, which prevents aluminum from stacking the polishing tank liquid level, resulting in insufficient brightness of the upper aluminum material.The effect of water leads to a lack of brightness, which is often overlooked.Dry aluminum is best used in chemical polishing bath fluids to prevent moisture from being introduced.2. White attachments:The morphology of the defect is a layer of white sediment on the chemically polished aluminum surface, the distribution of the defect is uneven, and the surface of the aluminum material at the base of the attachment may be corroded.Usually, the defect is caused by a large amount of aluminum dissolved in a solution of chemical polishing bath.Further confirmation can be made if the relative density of the solution is higher than 1.80.Measures should be taken to adjust the amount of aluminum dissolved in the tank to the normal range.Recommended Reading: "Aluminum Plate Electrolytic Capacitor Selection to pay attention to what Issues"Above are the defects and countermeasures of chemical polishing of anodized aluminum plate.Aluminum anodized plates are used as anodes in corresponding electrolytes such as sulfuric acid, chromic acid, oxalic acid, etc.Electrolysis is carried out under specific conditions and application of current.
