Hydrocarbons
It is an organic compound consisting of two elements, hydrogen and carbon. Most of the petroleum composition consists of hydrocarbons of varying lengths.
The smallest hydrocarbon methane consists of a single carbon atom and four hydrogen atoms. However, hydrocarbons can consist of hundreds or thousands of individual atoms linked together in many ways, including chains, circles, and other complex shapes.
In order to classify the properties of hydrocarbons, they are divided into several basic types.
Alkanes: These are called saturated hydrocarbons. That is, they only contain single bonds between all carbon atoms. Alkanes are the basis of petroleum fuels and exist in linear and branched forms.
Unsaturated Hydrocarbons: Hydrocarbons that have one or more double bonds between carbon atoms are called alkenes.
Cycloalkanes: Any hydrocarbon containing one or more ring structures.
Aromatic Hydrocarbons: Aromatic hydrocarbons , also called arenes, are a unique class of carbon molecules in which carbon atoms are bonded by successive double and single bonds. This class of molecules has special ring structures in which the bonds between carbon atoms are an intermediate bond between single and double bonds.
Molecules in this class contain the industrial solvent "benzene".
Benzene (C6H6): Like other hydrocarbons, benzene is a natural component of petroleum. It is a colorless, flammable, sweet-smelling liquid at room temperature and is a component of most gasoline blends because of its high octane number.
Benzene is also highly carcinogenic and is well known to cause bone marrow failure and bone cancer. Of course, its carcinogenicity is not well known when used as an additive in aftershave and other cosmetics due to its "pleasant aroma".
The largest use of benzene (50%) is the product of styrene and polystyrene plastics. It is also converted into a molecule known as cyclohexane, which is important in Nylon production. About 15% of benzene is used to produce cyclohexane. Smaller amounts are used in everything from pesticides to rubber.
The benzene structure can be drawn in two ways. In the first, the double bond character is drawn explicitly. In the short handed version, a circle is drawn inside the ring to show the structure. There is only one hydrogen bonded to each carbon atom in benzene.
I. and II below. drawings are identical. III in practice. drawing is used.
Benzene is a colorless, flammable liquid with a boiling point of 80.1 ° C and a melting point of 5.5 ° C.
Binuclear Aromatic Hydrocarbons: They are compounds that contain two benzene rings in their molecules.

plastic processing technique, It may sound quite simple in logic and working principle.
However, all plastics productions, from the simplest to the most complex product structure, are quite complex under this simple logical approach. It is not known that it is the work of technical information.
The main argument in the process is heat treatment. When thermoplastics are melted under temperature, they enter the fluid form. Extruders also work for this job. The resistances wrapped around the sleeve heat the sleeve and make the polymeric material in it fluid. The main equipment of the extruder is the screw, the core implementer of the extrusion business.
It is a processing technique in which the molten polymer is forced into a mold cavity under high pressure through an open channel (runner) and the polymeric melt is provided to take the mold form. Injection molding machine and extruders are very similar. The main difference between the two machines is the screwing process. There is constant forward pressure in the extruder screw. The screw of the injection molding machine does not only forward pressure, but also backward movement according to the steps of the molding cycle.
When an amorphous polymer is heated to the temperature at which the polymer structure becomes "viscous liquid or rubbery"; It is called the Glass Transition Temperature or Glass Transition Temperature (Tg). of amorphous polymer It is also defined as a temperature at which it acquires characteristic glassy state properties such as brittleness. It is measured in °C or °F.
This temperature depends on the chemical structure of the polymer and is therefore used to describe polymers.
The order of temperature breakpoints during the decomposition process of a polymer is as follows:
(Tg) Glass Transition Temperature < (Tc) Crystallization Temperature < (Tm) Melting Temperature
On our page, we bring together our manufacturers and suppliers serving the sector.

Basically, polymers that can yield low melt viscosity at an appropriate processing temperature and solidify within the eruption distance are are the preferred polymers in the process. Polymers are preferred in terms of granular size, rapid melting and providing a more even heat distribution. Polypropylene (PP) has exactly these desired properties. It is easy to process and forms a good mesh.

Not only the producers working in the plastics industry, but also the accounting personnel who know the name of the raw material only on the waybill, the purchasing who have no idea how and where the product they buy are used, the sales personnel and employees who do not know the stages in which the product they sell is produced, should have information about the sector in which they "ate their bread", It has been prepared with the belief that it will be appropriate in terms of awareness. It is also a training, information and solution platform that serves as a guide for enthusiasts and newcomers to the sector.
