Radiation Polymerization

The use of irradiation technology is big enough in the process of an industrial chemical. Because it brings high energy, radiation may act as a catalyst to stimulate the chemical changes suatuÆÒhan, one of which is to change the type of liquid chemicals from organic compounds in the class of monomers into polymers. One of these is the nature of the monomer when receiving radiation exposure can be turned into new materials called polymers, which is a very hard solid material at room temperature. Polymer-making technique with the help of this radiation is called radiation polymerization. In industry, radiation polymerization technology can be used to produce high-quality plastic because of its very strong and resistant to heat.

In general it can be said that the polymerization is an effort to combine several elements into one cohesive substance. Utilization of the results of irradiation in the polymer industry the most is for the manufacture of electric cable insulation material. Irradiation causes long-chain molecules in polymers holding in certain places that the process known as crosslinking (crosslinking). Radiation energy can stimulate the occurrence of crosslinking between the polymer thus formed three-dimensional network that can change the properties of polymers. These events actually cause cable insulation materials are more resistant to heat and high voltage electricity.

Conductor metals currently used for power transmission cables are still a prisoner-in, thereby causing electric current dialirkannya partly converted into heat which is known as Joule heating. The higher the temperature, the higher the resistance-in, so that more electrical energy converted into heat dialirkannya. Because of Joule heating, too, the strong currents flowing in the cable should be limited. That is why, certain electronic goods, computers for example, equipped with a fan to remove heat that occurs in the circuit-circuit.

PVC plastic is made of polymer material can maintain the density of the irradiation at much higher temperatures than ordinary PVC (the result of chemical processes). With this irradiation technology, cable insulation materials become stronger, more elastic, and more resistant to oils and other chemical solutions. This advantage can be achieved without causing changes in electrical properties as well as insulating power.

Irradiation technology can also modify polyethylene polymer product can be shrunk if the volume is given a heat treatment which is often referred to as heat shrinkable tubes. This product is widely used in the electric industry to insulate electrical connections. Heat shrinkable tubes are also often used in the telecommunications industry for the packing units such as cable telephone cable unit, to be shielded from outside influences, more durable, safe and can be planted in the ground.

Irradiation technology is very efficient and economical to manufacture polymeric small-diameter cable insulation material that is widely used in electronics industry which requires high accuracy, such as computers and telecommunications aircraft. For some types of electronics products, the use of high quality cable is often a necessary condition, so our product really can be reliable and competitive.

Very thin surface layer (membrane) on a silver oxide batteries used in digital watches and calculators, as well as the surface of the floppy disks and tape record the video tape, are processed using irradiation technology. Researchers from Japan have succeeded in making polymer membranes of cellulose that is used for microphone or a magnifying system of acoustic sound. This high-quality membranes are being developed for the manufacture of commercial sound systems and high-quality musical instruments. In the field of energy, solid polymer electrolyte (solid polymer electrolyte) can be used to manufacture chemical fotoelektro cells. These polymers are made from polyethylene oxide (PEO) that is coupled with potassium jodida (KJ) and jodium (J2). Research in this field still continues to be developed to obtain a system of solid polymer electrolyte which would later be used as batteries for solar electric generating systems (solar energy).
