Aluminum Alloy 7075
The alloys are classified and named according to the amount and type of the alloying metals . Given widespread applications across industries, selecting the right aluminum alloy type for a specific end-use is crucial. Just slight differences in chemical properties can drastically alter strength, workability, corrosion resistance, and electrical conductivity of the alloy.
Aluminum alloy 7075 is a heat-treatable aluminum alloy with zinc as the primary alloying element. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strength levels that are comparable to many steel alloys.
7075 offers good stress-corrosion cracking resistance. Known as a mainstay in the aerospace industry since it was introduced, Aluminum 7075 brings moderate toughness as well as an excellent strength-to-weight ratio. It is also important to note that at sub-zero temperatures Aluminum 7075 increases in strength. When it comes to welding, resistance welding is preferred, while gas and arc welding should be avoided.
Aluminum bevrages Can v1
An Aluminum can (British English: Aluminium can) is a single-use container for packaging made primarily of aluminum.[1] It is commonly used for food and beverages
The inside of the can is lined by spray coating an epoxy lacquer or polymer to protect the aluminum from being corroded by acidic contents such as carbonated beverages and imparting a metallic taste to the beverage.
Aluminum Oxide
The Production of Aluminum Oxide is by first digesting Bauxite ore, containing a maximum of 55% alumina, in a hot sodium hydroxide solution. At temperatures of around 175°C, the aluminum dissolves and forms sodium aluminate. High-purity alumina is filtered from the compound, and the resulting solution is transitioned to a precipitator tank for cooling. As it cools, the solution becomes seeded with extremely fine-grained aluminum hydroxide (Al(OH)3) crystals. These crystals are moved to a kiln for calcination at temperatures approaching 1,260°C, yielding aluminum oxide powder.
Aluminum Oxide is most significant use is in the production of aluminum metal, although it is also used as an abrasive due to its hardness and as a refractory material due to its high melting point.
High aluminum oxide refractories are a mainstay in petrochemical applications, particularly syngas reactors which have demanding thermochemical and thermomechanical process conditions. Another critical application of Al2O3 ceramics is in autothermal reforming (ATR).
Aluminum Profiles
The production of aluminum profiles typically involves a multi-stage process starting with raw aluminum, shaping it through extrusion, and then finishing with surface treatments. This process ensures the creation of high-quality profiles with specific shapes and properties.
The aluminum profiles are manufactured by aluminum alloy; they do not require painting, polishing and further process of the surface as steel does, they are Corrosion resistance , machinable , formable and recyclable .
The most important advantages of the profiles are light and durable .The connecting items have been specially designed for the profiles and they are easily and quickly placed.
Ammonium Chloride
It is an inorganic compound having a formula of NH4CI that dissolves easily in water, glycerol, methanol and polar solvents and It is acidic in nature as its pH ranges from 4.6 to 6. It is basically the salt of ammonia and hydrogen chloride with the boiling point of 520∘C 520∘C and melting point is 338∘C 338∘C .
ammonium chloride is as a source of nitrogen for several types of fertilizers, such as chloro-ammonium phosphate. It is used as a fertilizer as it is a large source of nitrogen and urea.
It is used in bread making as a yeast nutrition also used to produce many medicines and cough syrups, reducing nausea and vomiting and in many other pharmaceutical industries.
Ammonium Nitrate
Ammonium nitrate is an ionic salt formed by one positive (NH4)+(NH4)+ and one negative ion (NO3)−(NO3)−. It is a white crystalline solid and is soluble in water. It is also used in ammonia dynamites and also as oxidizing agents in ammonals.
Prilled fertilizer forms when a drop of concentrated ammonium nitrate solution (95 percent to 99 percent) falls from a tower and solidifies. Low-density prills are more porous than high-density prills and are preferred for industrial use, while high-density prills are used as fertilizer.
Ammonium nitrate is a popular fertilizer since it provides half of the N in the nitrate form and half in the ammonium form. The nitrate form moves readily with soil water to the roots, where it’s immediately available for plant uptake. The ammonium fraction is taken up by roots or gradually converted to nitrate by soil microorganisms. Many vegetable growers prefer an immediately available nitrate source of plant nutrition and use ammonium nitrate.
Ammonium Sulfate
Chemical properties
- Chemical formula: (NH4)₂SO₄
- N content: 21%
- S content: 24%
- Water solubility: 750 g/L
- Solution pH: 5 to 6
Ammonium sulfate is most widely used nitrogen (N) fertilizers for crop production, where both N and sulfur (S) are required and It provides an excellent source of S, which supports or drives numerous essential plant functions, including protein synthesis.
Because the N fraction is present in the ammonium form of ammonium sulfate, rice farmers frequently apply it to flooded soils, since nitrate-based fertilizers are a poor choice due to denitrification losses. A solution containing dissolved ammonium sulfate is often added to post-emergence herbicide sprays to improve their effectiveness at weed control.
Anaerobic Adhesives
A range of viscosities are available, from four to several million centipoise, and the shelf life is greater than one year, depending on the amount of air in the container. Anaerobic adhesives can fill bond gaps from 0.025 mm (0.001 inches) to ∼1 mm (0.04 inches).
Anaerobic adhesives are used for structural bonds, primarily with materials such as metals and glass and to a lesser extent, wood and plastic (thermosets and some thermoplastics). An activator is applied to one or both joint surfaces; adhesive is then applied to one surface to begin curing. Cure speed is determined by the choice of activator; cure times range from less than 30 seconds to greater than 30 minutes.
Joints produced using anaerobic adhesives can withstand exposure to organic solvents and water, weathering, and temperatures of up to about 200°C. The product has excellent chemical resistance but is not recommended for exposure to concentrated acids and alkalis. In general these products are suitable for maximum temperature up to 150 deg. C. However some grades are available that can withstand higher temperature in case of need
Anhydrous Ammonia
Anhydrous Ammonia is a clear, colorless gas at standard temperature and pressure conditions and has a very characteristic odor. The odor is the strongest safety feature of the product.
Anhydrous ammonia is transferred and stored as a liquefied, compressed gas and is relatively easy to handle with readily available equipment designed for ammonia service.
Anhydrous ammonia, is a starting material for the production of ammonium nitrate; it can also be used as the recirculating fluid in refrigeration systems
Ammonia is a chemical compound used as a fertilizer because it is rich in nitrogen. Its chemical formula is NH3, which means that it consists of one atom of nitrogen and three atoms of hydrogen per molecule.
Aseptic Bags
Several materials are layered together to provide the level of protection required for aseptic packaging standards, including:
- Polyethyleneis used as a barrier on the inner and outer sides of aseptic packaging. These layers protect against moisture entering or exiting the container.
- Film foilhelps preserve the product by keeping light and oxygen out.
Aseptic bags are widely used in aseptic solid raw materials, sterile pharmaceutical auxiliary materials, sterile preparations and the like due to their sterility, non-toxicity, excellent low-temperature resistant performance, good chemical stability and electrical insulation properties. Transit and temporary storage of pharmaceuticals and chemical products.
in the food industry, aseptic packaging bags are divided into high volume aluminum-plastic composite aseptic bags (5 ~ 200L) and low volume co-extruded film aseptic pouches (200 ~ 500ml); aseptic bags can also be used with cardboard The paper-based multi-material composite packaging containers, which consist of aluminum foil and food, contain about 20% of the entire packaging weight, and mainly block the effects of liquid leakage and microbial invasion. They are perfect packaging materials for juices, jams, dairy products and other foods.
