El aluminio es uno del campo emergente de productos de aluminio marino, así como mucha transformación del negocio interno de procesamiento de aluminio y mejora de las direcciones principales. Debido a que el aluminio se utiliza en el campo de las embarcaciones marinas, etc., de modo que no sean productos de aluminio ordinarias, no son más estrictos requisitos del proceso y las normas de rendimiento.
![[Image: cuatro-principios-de-selecci%C3%B3n-del-...marino.jpg]](http://www.alu-hm.com/wp-content/uploads/2017/07/cuatro-principios-de-selecci%C3%B3n-del-aluminio-marino.jpg) [img=652x0]http://www.alu-hm.com/wp-content/uploads/2017/07/cuatro-principios-de-selecci%C3%B3n-del-aluminio-marino.jpg[/img]
principio de selección de aluminio marino puede ser dividido en cuatro zonas. En primer lugar, de alta resistencia específica y módulo específico, están estrechamente relacionados con la resistencia estructural y el rendimiento de resistencia y módulo de elasticidad del material y el tamaño del barco, debido al módulo de elasticidad y la densidad sustancialmente la misma aleación de aluminio, la adición de elementos de aleación tiene poco efecto, aumentando así la resistencia a la deformación en una gama de potente estructura del buque atenuante. De alta aleación de aluminio fuerza es a menudo difícil de tener también una excelente resistencia a la corrosión y soldabilidad. Por lo tanto aleación marina son generalmente fuerza moderada, aleaciones resistentes a la corrosión soldable. En segundo lugar, excelentes propiedades de soldadura. Actualmente barco se utiliza principalmente en un método automático de soldadura TIG, grietas tienden buena soldabilidad significa una aleación de aluminio durante la soldadura es más pequeño, es decir, a una aleación de aluminio que tiene buena resistencia de soldadura grieta. Debido a que la nave por las condiciones de tratamiento térmico no puede restaurar vuelto a perder la capacidad de soldadura. En tercer lugar, excelente resistencia a la corrosión, muchos medio ambiente del agua de mar dura y embarcaciones marinas usado en la estructura, por lo tanto, resistencia a la corrosión es uno de los principales signos de aleación de aluminio marino. En cuarto lugar, una aleación de aluminio que tiene buena formabilidad caliente y fría, debido a que el recipiente a fabricar mediante diversos procesos dió el procesamiento en frío y en caliente, que debe ser fácil para el envío proceso de moldeo de aluminio, sin defectos de craqueo, y aún así cumplir con fuerza, y después del procesamiento requisitos de corrosión.
Selección de aluminio marino más estrictas, más corriente se utiliza en lasaleaciones 5083, 5086, 5454, 5754, 6061 y otros productos de aluminio. En las aplicaciones prácticas, las ventajas de aluminio marino es muy obvio. En primer lugar, un pequeño peso específico, reducir barcos pesados, el ahorro de consumo de energía, aumento de la capacidad de carga, seguido por una buena resistencia a la corrosión, un coste reducido, aceitado, extender la vida útil; tercera soldadura, número de conformabilidad, facilita el procesamiento posterior; final de aluminio fácil de reciclar los residuos, que puede ser reciclado, al mismo tiempo, no se quema, la seguridad contra incendios.

| Dangers of aluminum foil |

Aluminum foil should ideally be used only to keep food warm for shorter periods of time but many people store the food for longer which may have consequences. Any food, if reaches 7- 8 degree Celsius or the time limit of 3-4 hours has exceeded (this may vary depending on the season and outdoor temperatures) then it provides an atmosphere for bacteria to reproduce, so it shouldn’t be outside the refrigerator. The bacteria (lysteria, staph) developed on the food will not be visible but it may cause food poisoning, clammy skin and vomiting.
According to Shalini Manglani, Bangalore based Wellness and Weight Management Expert, “Muslin cloth, food grade brown paper and food grade parchment or butter paper can also be used to wrap foods. Aluminum foil locks moisture and odor in and keeps the food fresh but hot and acidic foods should not be put in aluminum foil as the aluminum will leach into the item.”
parchment paper
Parchment or butter paper can also be used to wrap foods.
Although aluminum foil is there to keep your food warm, it doesn’t harm to try other alternatives too as suggested by experts. For most working people, eating packed homemade food is a norm. All you need to do is give a little attention to how this food is packed and carried. Be Safe!

| How Do Aluminum Foils Work? |

An aluminum foil keeps the food warm, but placing the foil directly on the object or food doesn’t help much. The reason behind this is, if the foil is in contact with the object, the thermal energy would move in the foil itself and might get away, but if the foil is placed a little away from the food then it can properly reflect back the thermal energy and maintain the freshness of the food. So to avoid contact between foil and food, you can add a few layers of butter paper to make air pockets and then add pack in a final layer of aluminum foil.
As aluminum is a poor insulator (substance which doesn’t allow passage of heat) so to make the foil more effective, place it (food wrapped in foil) in fiberglass or ceramic tiffin boxes. It doesn’t only keep the food warmer for long, but also keep things cold.It acts as barrier to the oxygen and air which can transfer heat to the cold or frozen food. Bottom line is it helps by maintaining the temperature of the food, be it warm or cold.

| What's the Difference Between Regular and Heavy-Duty Aluminum Foil? |

Aluminum foil is a kitchen essential. If you're like us, you use this workhorse for wrapping up leftovers, packaging food for the freezer, and lining baking sheets and grill grates. It can even be a cooking vessel all on its own, which is especially handy if you're short on pots and pans (or just don't feel like cleaning).
5 Ways to Use Aluminum Foil to Clean
So the question when it comes to buying a roll of foil is not if you'll buy a roll, but which kind you'll buy: regular or heavy-duty?
The Difference Between Regular and Heavy-Duty Aluminum Foil
Regular and heavy-duty aluminum foil are made of the same material, but there's a key difference: the thickness of the foil.
So what? you might be thinking. Where this really matters is when you're using aluminum foil for cooking. Since regular aluminum foil is thinner than the heavy-duty version, it doesn't stand up to high heat and weighty items as well.
More About Regular Aluminum Foil
Any aluminum foil that's simply labeled "aluminum foil" is considered regular aluminum foil. In addition to being thinner, it's also less expensive than heavy-duty foil: A 200-square-foot roll of Reynold's Wrap Aluminum Foil costs $9.19 on Amazon. For roughly the same price ($8.99), you'll get a 130-square-foot roll of Reynold's Wrap Heavy-Duty Aluminum Foil.
Regular aluminum foil will definitely work for kitchen tasks like covering dishes to be stored in the fridge, wrapping sandwiches and other foods, and lining baking sheets. But regular foil doesn't hold up as well with heavy foods or with high-heat cooking on the grill, where it's more likely to tear, rip, or break.

More About Heavy-Duty Aluminum Foil
As the name implies, this type of foil is thicker and sturdier than regular aluminum foil. It's tough enough to stand up to high heat, heavy food items, and long-term storage in the freezer. Because of the extra thickness, it's also a better choice for campfire packets. And, as noted above, while prices vary from brand to brand, you can always expect to pay more for heavy-duty foil.
The Bottom Line: Is Heavy-Duty Aluminum Foil Worth It?
Here's an easy way to simplify things if you're still not sure which one to buy: Remember that heavy-duty aluminum foil can do everything that regular foil can do, but it doesn't work the other way around. You can stick with the regular stuff for basic tasks like covering or wrapping foods and lining baking sheets, but go for heavy-duty foil for grilling and freezer storage.

Aluminum foil isn't considered dangerous, but it can increase the aluminum content of your diet by a small amount.
If you are concerned about the amount of aluminum in your diet, you may want to stop cooking with aluminum foil.
However, the amount of aluminum that foil contributes to your diet is likely insignificant.
As you are probably eating far below the amount of aluminum that is considered safe, removing aluminum foil from your cooking shouldn't be necessary.

Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It's made by rolling large slabs of aluminum until they are less than 0.2 mm thick.
It's used industrially for a variety of purposes, including packing, insulation and transportation. It's also widely available in grocery stores for household use.
At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.
People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue.

The process of anodising aluminium drawing is mainly about surface treatment of aluminium plate
Anodising of drawing technology has become the industry's a very important mechanical processing link, because by anodising brushed aluminium plate is not only the surface looks beautiful appearance generous, and also has many advantages in the application process, compared with the other plate is much longer service life.Because the plank after anodising is especially suitable for used in some special environment, in the aviation design and manufacture many parts will use the brushed anodising aluminium, even some environment is bad weather or under pressure, brushed anodising aluminium also won't appear deformation.Despite the excellent performance of the anodising aluminium plate, there are many matters needing attention during the anodising process.
And what are the things that we need to pay attention to during the whole production process?One of the most critical is the anodising surface treatment technology, about the process, we is the most easy to understand and master the anodising aluminium surface polishing, because of the anodising process itself is a kind of surface with metallic simple sense and look round plate, so in each brushed anodising aluminium production is completed, is there will be a polishing process, on the plank after polishing is what is a complete anodising brushed aluminium plate.Of course, in addition to the above procedures, we also have degreasing, silk, pickling, cleaning and other steps and procedures are indispensable in the process of surface treatment.
So anodising brushed aluminium plate, the key lies in surface treatment and surface treatment requirement is very high, but at present a lot of processing enterprises for the above process have standardized operation, in most of the factories have adopted the machinery to replace manual operation link, but need to be worth what carry is, as long as a process problem, will directly influence the final effect of anodising brushed aluminium plate.

1. The current density: within a certain limit, the current density increases, the membrane growth rate increases, the oxidation time is shortened, the membrane is more porous, and the hardness and wear resistance are higher.If the current density is too high, the heat of the parts will be overheated and the temperature of the local solution will rise, the dissolution rate of the membrane will be increased, and the possibility of burning the parts will be burned.The current density is too low, and the film growth rate is slow, but the film is dense, and the hardness and wear resistance are lower.
Clear anodized aluminum, which is used for protection, decoration and pure decorative processing, USES the upper limit of the allowable concentration, which is 20% concentration of sulfuric acid for electrolyte. 【clear anodized aluminum】
2. Oxidation time: the choice of oxidation time depends on the concentration of the electrolyte, the temperature, the anode current density and the required film thickness.Under the same conditions, when the current density is constant, the growth rate of the membrane is proportional to the oxidation time.But when the film growth to a certain thickness, due to the membrane resistance increases, affect the conductive ability, and because the temperature rise, the dissolution rate of membrane increases, so the film growth rate will decrease gradually, until the last no longer increases.
3. Concentration of sulfuric acid: usually 15% - 20%.Concentration increases, the dissolution rate of membrane increased, the growth speed of membrane, membrane of high porosity, adsorption capacity is strong, flexible, good dyeing (easy to dye the dark), but the hardness, wear resistance of slightly;And the concentration of sulfuric acid was reduced, and the growth rate of the oxide film was accelerated, the pores of the membrane were low, the hardness was high and the wear resistance was good. 【clear anodized aluminum】
4. Electrolyte temperature: the electrolyte temperature has a great influence on the quality of the oxide film.Temperature rise, film dissolution rate increases, film thickness decreases.When the temperature is 22-30 ℃, the resulting film is soft, good adsorption ability, but wearability is poor;When the temperature is greater than 30 ℃, the film became loose and uneven, and sometimes even discontinuous, and the hardness is low, thus lost the use value;When the temperature is between 10-20 ℃, the generated porous oxide film, adsorption ability, and full of elasticity, suitable for dyeing, but the film hardness is low, poor wear resistance;When the temperature is below 10 ℃, the increase of the thickness of the oxide film, high hardness, good wear resistance, but low porosity.Therefore, the temperature of the electrolyte must be controlled strictly.In order to make a thick and hard oxide film, the operating temperature must be reduced. In the process of oxidation, the compressed air should be stirred and the lower temperature is used. 【clear anodized aluminum】
5. Mixing and moving: can promote the electrolyte convection, strengthen the cooling effect, ensure the uniformity of the temperature of the solution, and not cause the degradation of the oxide film due to the local heating of the metal.
6. Impurities in the electrolyte: the possible impurities in the electrolyte used in the oxidation of aluminum anodes are Cl - inverse, F inverse, NO3 inverse, Cu2+,Al3+,Fe2+ etc.Among them, Cl - inverse, F - inverse, NO3 - induced porosity increase, surface roughness and porosity.If its content exceeds the limit value, it may even cause corrosion perforation of the making parts (Cl shall be less than 0.05g/L, and F inverse should be less than 0.01 g/L);When the Al3+ content exceeds a certain value in the electrolyte, the surface of the workpiece often appears white or speckled white, and the adsorption performance of the film decreases, and the dyeing difficulty (Al3 + should be less than 20g/L).When Cu2+ content reaches 0.02 g/L, dark streaks or black spots appear on the oxide film;Si2+ is often suspended in the electrolyte, causing the electrolyte to be microturbid and adsorbed on the membrane with a brown powder.
7. All landowners aluminum alloy components: in general, the quality of the other elements make the film of aluminum metal drops, and didn't get the pure aluminium oxide layer with the thickness, hardness too low, different composition of aluminum alloy, in the anodic oxidation process should pay attention to not with groove.
