Полипропилен (ПП)

۲۱ بازديد

Полипропилен (ПП) — это разновидность проолефина, который немного тверже полиэтилена. Полипропилен – товарный пластик низкой плотности, устойчивый к высоким температурам. Среди применений полипропилена можно упомянуть использование в упаковке, автомобилях, товарах народного потребления, медицине, а также в производстве литой пленки, а его химическая формула – (C3H6)n.

Полипропилен (ПП) делится на две категории: гомополимер и сополимер полипропилена. Далее были проверены:

Полипропиленовый гомополимер

Это термопластичные смолы, которые производятся путем полимеризации пропилена с помощью катализаторов Циглера-Натта. Гомополимеры можно использовать в различных технологиях обработки, таких как литье под давлением, выдувное формование, пленка, волокно, экструзия листов и термическое формование.

В дополнение к вышеуказанным применениям, гомополимерный полипропилен PPH обладает такими характеристиками, как более высокое соотношение прочности к весу, более длительный срок службы и большая жесткость материала по сравнению с сополимером полипропилена, а также для применений, требующих хорошей устойчивости к ударам, коррозии и химикатам. Он требует хорошей свариваемости и технологичности.

Полипропиленовый сополимер

Сополимеры имеют второй мономер этилен, который увеличивает ударную вязкость по сравнению с гомополимером полипропилена. Ключевыми свойствами сополимера полипропилена являются высокая ударная вязкость, хорошая химическая стойкость, лучшая стойкость к растрескиванию при низких температурах и повышенная гибкость.

Polypropylene (PP)

۱۵ بازديد

Polypropylene (PP) is a type of proolefin that is a little harder than polyethylene. Polypropylene is a commodity plastic with low density and resistant to high heat. Among the uses of polypropylene, we can mention the use in packaging, automobiles, consumer goods, medicine, and cast films, and its chemical formula is (C3H6)n.

Polypropylene (PP) is divided into two categories: polypropylene homopolymer and copolymer. In the following, they have been examined:

Polypropylene homopolymer

They are thermoplastic resins that are produced through the polymerization of propylene with Ziegler-Natta catalysts. Homopolymers can be used in various processing technologies such as injection molding, blow molding, film, fiber, sheet extrusion and thermal forming.

In addition to the above applications, PPH homopolymer polypropylene has features such as higher strength-to-weight ratio, longer durability, and greater material stiffness compared to polypropylene copolymer, and for applications that require good resistance to impact, corrosion, and chemicals. It needs good weldability and processability.

Polypropylene copolymer

Copolymers have a second monomer of ethylene, which increases the impact strength compared to polypropylene homopolymer. The key properties of polypropylene copolymer are high impact strength, good chemical resistance, better resistance to cracking at low temperatures and increased flexibility.

"Moplen EPD60R"

Polypropylene (PP) is a lightweight, hard, rigid and crystalline thermoplastic that exists in various forms. Among the advantages of polypropylene, we can mention its melting point, density, chemical resistance and flammability.

Petrochemical raw materials

۱۶ بازديد

Petrochemicals are actually substances that are obtained from oil in trace form. Also, some chemical compounds made from oil are also obtained from other fossil fuels such as coal or natural gas or renewable resources such as corn, dates and sugarcane.

Materials made from petrochemicals include items such as soap, detergents, solvents, drugs, fertilizers, pesticides, synthetic rubber and rubber, explosives, paints, epoxy resins, insulating materials, urea, sulfur, gasoline, diesel. , bitumen, etc.

Petrochemicals are often composed of carbon and hydrogen and are called hydrocarbons. If the atoms in the molecules are connected to each other by a single ion, the molecule is said to be saturated. Also, if they are connected to a monolayer by one or more double bonds, they are unsaturated molecules. Unsaturated chemicals are used as petrochemical feedstock due to their reactivity and can easily be converted into other petrochemical materials.

Petrochemical raw materials

They are divided into three general groups: olefins, aromatics and synthetic and inorganic gases. Olefins whose molecules form straight and unsaturated chains include ethylene, propylene and butadiene. Ethylene is the primary hydrocarbon material that is used in the largest volume in the petrochemical industry.For example, ethylene glycol is made from ethylene, which is used in polyester resin fibers and in antifreeze. Propylene is also used in the manufacture of products such as acrylic, rubbing alcohol, epoxy glue, paper coverings and carpets.

Aromatics are hydrocarbon molecules that form rings and are unsaturated. The main raw materials include benzene, toluene, xylene and naphthalene. Benzene is used to make styrene, the raw material of styrene plastic. It is also used to make paint, epoxy resin and glue.Toluene is used to make solvents, gasoline additives and explosives. Xylene is also used in making plastics, synthetic fibers and gasoline refining. Naphthalene is used significantly in the manufacture of insecticides.

Synthesis gases are used to produce ammonia and methanol. Ammonia is primarily used to form ammonium nitrate and a source of fertilizer. Most of the methanol produced is used to make formaldehyde, and the rest is used to make polyester fibers, plastic and silicone rubber.

The petrochemical industry got its impetus in 1913 from the development of the thermal cracking process by which crude oil was refined. The process produced gas byproducts that were initially used only as lighting gas or fuel, but in the 1920s and 30s were useful as chemical raw materials.

Polystyrene compound ps

۱۴ بازديد

Polystyrene compound is a hard, rigid and transparent synthetic resin that is produced from the polymerization of styrene, which is one of the polymer raw materials. Polystyrene is used in the food service industry as rigid trays, disposable dinnerware, and foam cups, plates, and bowls.

Polystyrene compound has a uniform texture in terms of variety and distribution and has a good balance between hardness, toughness and impact resistance. It is also produced in the form of granules and has a white color.

Polystyrene compound can also be mixed with other polymers to add stiffness and strength to important plastic and rubber materials. Polystyrene is one of the raw materials of plastic, and due to its low production cost, ease of shaping the melted polymer in injection molding operations, and its optical and physical properties, it is widely used and has become one of the modern plastics.

Polystyrene compound is actually a combination of polystyrene raw materials, coloring materials and reinforcement, which improves its physical properties and desirable properties. This product is highly resistant to shock and impact.
