The aluminum powder has lightweight, high buoyancy, strong hiding power


What does aluminum powder look like?
Silver metallic pigment is aluminum powder. You make it by adding some powder to pure aluminum foil. After crushing, you then grind it into scaly powder and polish it. This aluminum powder can be lightweight, light, with high buoyancy and strong hiding powers. Aluminum powder can be treated to make it non-floating. You can use aluminum powder to make fireworks and fingerprint identification. Due to its many uses and high demand for aluminum powder, it has been a popular class of metallic colors.


For what purpose is aluminum powder used?


Scaly aluminum powder particles are used to make the pigment. The aluminum powder’s metallic shielding and color is precisely due to its scaly particles. Since long ago, industrial production of aluminum powder from metal has been possible. Early production methods used the ramming technique. The aluminum crumbs had to be placed in the hole of the punching machine. Machine drove the ramming plow to continue punching the aluminum crumbs. After impact the aluminum ductile becomes flaky and shatters under pressure. It is removed as a product after the aluminum has become very small and thin. This ramming process is extremely inefficient. The product quality is poor. Also, there are a lot dust particles that is easy to ignite and catch fire.

German Hamtag invented a ball mill in 1894 to create aluminum powder. To make the aluminum powder, steel balls, aluminum scraps and other lubricants, they used a ball mill. The aluminum scraps were then crushed with flying steel balls. Dry production is the name for gas. J. The addition of petroleum solvent in the ball mill was invented by J. The process is very simple and safe. It has been quickly adopted in many countries around the world. The “wet method” is the most common method for producing aluminum powder pigments. Many types of fireworks can be made from aluminum powder. You can also use it to make certain kinds of electronic items. Aluminium powder can be found in many sealants and paints.


Are aluminum powders dangerous?


Exposed to fine dust may cause scarring and pulmonary fibrosis. This can be accompanied by shortness of breath, coughing, and a loss of appetite. Aluminum powder, which is a flammable liquid, can pose a danger to your health.

Powder coating presents a much lower risk than regular paint. Powder/air mixture has a 50-100x higher ignition energy than solvent/air mix. But, any flammable powder, or dust, will combine with air to form an explosive mixture, which can be dangerous. If the necessary precautions are taken before transporting, storing, or processing, you can make sure that they do not explode with air. Safety reasons dictate that the maximum powder concentration for the different powders listed above must not exceed 10g/m3. The spray area often exceeds this limit. This is because there is always enough oxygen. It is essential to prevent sparks from exceeding this energy.

Comparing with resin powder that is not pigmented, adding 5-6% aluminum powder to the mix will increase its powder constant (Dust Constant), and explosion pressure by 10%. As the aluminum content increases, so will the explosive power. Aluminum powder with a higher than 25% aluminum content will have the same explosive power as pure metal powder. This dependency on aluminum powder colors does not result in the lowest amount of initiation energy. No matter what dispersion technique is used, pure resin powder will not reach the ignition energy. It is possible to reduce the ignition energy by using fine particles and uncoated aluminum.

The aluminum powder-containing powder coatings can be used in the same way as regular pigmented powder coats. They are safe as long they don’t exceed this limit.

For safety reasons, the spraying process must not be affected by aluminum powder. Solvent-based coatings with copper and gold powder also need to meet these basic requirements. Copper-zinc alloy powder has a lower explosion hazard than aluminum powder.


Aluminium powder: Characteristics


Aluminium powder for pigment is a powder of aluminum that has scales and is covered with a coating. This aluminum powder can be used as sandpaper. A mixture of aluminum powder powder and solvent is called aluminum powder paste. This paste is similar in use to aluminum powder. The output and dose are higher because it’s easy to use. The following characteristics are more common in aluminum powder pigments than those of other pigments:


1. These are some of the features of scaly coverage


Aluminium powder particles have a scaly appearance. Their ratio of thickness to diameter is between 40:1 and 100:1. Once the aluminum powder has been dispersed in the carrier it will have the property of being parallel with the substrate. Multiple aluminum powders may be linked. Each particle is connected to form a continuous film of aluminum powders that covers the substrate. The coating film reflects sunlight outside. This is how aluminum powder hides its true identity. Surface area is the ratio of thickness to diameter that determines aluminum powder’s concealability. Aluminum is stretched during the grinding process, the diameter-to-thickness ratio continues to increase, and the hiding power also increases.


2. Aluminium powder offers shielding qualities


To form an aluminum powder layer that is continuous, the aluminum powder in the carrier layer must float parallel to it. Because the pores are stratified between aluminum powder layers, external moisture and gas can’t pass through them to the substrate. This protects the aluminum powder well.


3. Aluminium powder’s optical properties


Aluminium powder can be made from aluminum with a light metallic color. Smooth, it can reflect visible light up to 60%-90% and ultraviolet light up to 90%. A paint made of aluminum powder is applied to the object, making it shiny and bright. This reflective light is a characteristic of aluminum powder.


4. Aluminium powder’s “two-color effect” properties


Aluminum powder can have metallic luster characteristics and is parallel to coated objects. Transparent pigments can change the appearance of the aluminum powder’s gloss and depth depending on the angle at which the light hits it. It is also known as “two-color effects”. In the coating film, aluminum powder is placed at different levels. Each layer of aluminum flake is illuminated by the incident light. The coating film with different thicknesses will be weakened in a different way, and the brightness of the reflected sunlight will differ. Infrared light that passes through transparent powders or aluminum powders is transformed into colored light. It then reflects off different aluminum powder levels, causing changes in brightness and color tone. This property of aluminum powder is widely used to coats like metallic paint or hammerpaint.


5. Aluminum powder’s floating characteristics


Large quantities of aluminum paste and powder for pigments are available in the floating variety. This type is known to have scaly floating along the surface.


This functional and fully-functional electric motorcycle was 3D printed from aluminum powder


Airbus, well known for their giant airplanes, is now producing 3D bikes! Light Rider, an electric bicycle that 3D printers can create is known as the Future of Electric Cars.

This 3D bike was launched by APWorks, a subsidiary of Airbus, and was described by them as “corrosion-resistant, combined with lightweight aluminum and almost specific strength titanium.” Scalmalloy has been specially developed for APWorks, and these unique qualities result from its use. This aluminum powder has been extensively researched.

What is the best way to powder print a strong bicycle frame? Airbus explained that Light Rider parts consist of thousands upon thousands of layers about 60 microns thick. Another feather is added by the hollow frame, which 3D-printed electric bikes add to their lid. Comparing to other bicycles the overall weight of this frame has been reduced by 30%. Joachim Zettler, Airbus APWorks GmbH CEO (Joachim Zettler), stated that the bicycle cannot be used for traditional milling or welding techniques. The team decided to use a hollow, complex, branching structure. The Light Riders are now less than 35kg each.

Light Rider may seem like a toy. However, it is practical and versatile. Light Rider can go up to 49 miles per hour, but it isn’t a Harley. It is intended to be used primarily in urban driving and 3D printed electric bikes. Airbus states that the battery will travel approximately 37 miles per charge.
