Due to its physical and chemical properties, aluminum powder is used as one of the most important raw materials in the production of automobile and airplane parts. This material is known as one of the most important metals in the automotive and aircraft industry, and due to its anti-corrosion properties, lightness, and high resistance to pressure and heat, it is used to produce various parts such as car body, brake disc, fan, etc. .
The added value of aluminum powder in the production of automobile and aircraft parts is very high due to its high physical and chemical properties. The use of aluminum powder in the production of parts reduces the weight of the parts, increases the resistance to pressure and heat, reduces the cost of production and increases the life of the parts. Therefore, it can be said that increasing the use of aluminum powder in the production of parts increases the quality and improves the performance of cars and airplanes.
ABS wastes are mostly used in refrigerators, tees, and electrical outlets.
Milled ABS waste
Granular gray ABS waste is mostly used in automobile manufacturing, counters and fans.
Due to the fact that there are different types of polyamides, different methods are used to recycle each of them. For example, a new method called Econail recycling is used to recycle nylon 6. In this recycling method, threads are extracted from the nylon product that will be used in other related industries. Also, in order to recycle all kinds of plastics, especially in the food industry, first by crushing them, they create smaller pieces, and then they melt them and start producing the product again. Due to the different chemical structure of polyamides, during recycling, each type of plastic material must be recycled with its own type and melted separately because their melting point is different from each other.
Recycled polyethylene granules are obtained from the recycling of waste of this group of polymers. Polyethylene is one of the most widely used polymers in the world. Proper processability is one of its important characteristics. Different grades of polyethylene are produced, each of which has a different molecular weight. Recycled polyethylene granules are usually known as inflatable granules, pipe granules and hash granules.
Recycled polyethylene can be used in the production of household and kitchen items. Of course, it should be said that its preparation can be much cheaper than other plastics. Other cases that can be used for this widely used granule are nylon bags and some bottles and three-dimensional car floors.
Polypropylene, abbreviated PP, is one of the materials used in the packaging industry, and only 3 to 5 percent of it is recycled in the United States, and most of it ends up in landfills. Recycled PP is seen in gray or black, which is not suitable for packaging at all. Anyway, recycled PP is used to make car parts, park benches, speed bumps, etc.
Acrylonitrile Butadiene Styrene ABS is a matte engineering polymer that is widely used in the electronics industry, consumer products, pipes and connectors, Lego toys, etc.
ABS polymer ABS is an impact-resistant and amorphous engineering thermoplastic. This polymer is made of three types of monomers: acrylonitrile, butadiene and styrene.
The important properties of ABS mentioned in the above sections, such as impact strength, etc., have made ABS a widely used polymer in various industries. The most important ABS polymer compounds are:
• Automotive: It is an important substitute for some metal parts and will reduce the weight of the product. Such as: dashboard components, door handles, seat belt components, etc.
• Electronics and computer: keyboard and..
• Household appliances: such as parts and frames of shavers, vacuum cleaners, food processors, refrigerators, etc.
• Pipes, fittings and hoses: due to corrosion resistance, suitable transportation, impact resistance even at low temperatures
• Sports equipment and…
polystyrene is a type of aromatic synthetic polymer that is created from styrene monomer and is actually a liquid hydrocarbon and one of the petroleum derivatives. PS is solid at room temperature and has a flexible structure, but at higher temperatures it melts and can be molded. Polystyrene is currently used due to its light weight, high resistance, economy, high efficiency and high thermal insulation. Polystyrene is a transparent thermoplastic that is used to produce a wide range of consumer products. This product is available as a solid plastic and as a rigid foam material. Solid type polystyrene is used in the production of laboratory tubes, CD holders, disposable containers, food packaging, etc. In some cases, it is mixed with colored materials, additives and other plastics and used in the production of household appliances, electronic appliances, toys, vases, etc.
Polycarbonate is placed in the category of transparent and flexible thermoplastics. High strength, suitable thermal resistance, ability to use in different colors and designs, resistance to penetration of ultraviolet rays, good stability, etc. have made this polymer to be used in various cases. One of the most practical forms of this product is its sheet, which is widely used in household, agricultural, electrical and electronic applications, etc.
Polypropylene is a thermoplastic polymer that is used in a wide range of applications including film and sheet, blow molding, injection molding, food packaging, textile, laboratory and medical equipment, pipe, industrial and construction applications, and automotive components. In addition, the polymer produced from propylene monomer is usually resistant to chemical solvents, bases and acids. The code is the characteristic of this polymer.
Polyethylene terephthalate (PET) is a thermoplastic polyester resin with the chemical formula (C10H8O4)n. Such resins can be divided according to viscosity. Low viscosity PET has a viscosity of less than 0.75, while high viscosity type has a viscosity of 0.9 or higher. This polymer is practically unbreakable, colorless, light in weight, and belongs to the category of transparent polymers.
The strength of PET is high and it shows itself especially in beverage bottles, making this material suitable for making portable and sports bottles. Transparency makes the contents of the containers visible, which is a very important point in the food business.
The weight of PET bottles is very low and has been decreasing in recent years, so that today the weight of these bottles is between 20 and 30 grams. One of the important properties that has made this compound suitable for many applications is its high strength in combining with other thermoplastic polymers such as polyethylene, polypropylene, polycarbonates, polystyrene, ethyl vinyl acetate, etc.
Linear low density polyethylene (LLDPE) and linear very low density polyethylene (VLDPE) include a wide range of polyethylenes from clear and elastomeric to opaque and rigid and dry. These grades are used when high stiffness and strength are considered along with low density and high flexibility. The important application of LLDPE is in the production of plastic films such as inflatable film, casting film, extrusion coating and food packaging.
Monoethylene glycol or MEG is an important solvent with a chemical formula of C2H6O2, a molecular weight of 62 grams and a melting point of -12.9ºC. A polar compound in the form of a colorless, odorless liquid with a sweet taste and soluble in water. This compound is considered one of the most important commercial glycols and is used as a raw material for industrial purposes such as making polyester fibers, fabric and polyethylene terephthalate (which is used in bottle production). Its other uses include cooling, heat transfer fluid, antifreeze and hydrate inhibitor in gas lines.
