The Plastic Manufacturing: Good Points and Possible Uses
Plastic is a durable and cheap material, and can be manufactured so that it’s possible to use it in various fields.
For example, in sewage systems and hydraulics in general the PVC tanks are useful, while in the construction field, agriculture and others you can used, among the other things, PVC connections. Hence, constructions and systems are partly built in plastic materials of various kind, recognizing their resistance and their qualities, which make of it a suitable material for many uses.
In some parts of the sewage systems plastic has a fundamental role: the modern polythene shafts are very used, while in the dumping grounds the use of plastic is necessary to waterproof the area, to avoid polluting the surrounding areas, and also to catch biogases and use their energy.
Summing up, the uses of the plastic materials also have an ecological background, thanks to their renowned waterproof quality: they can wrap polluting elements of various kind avoiding their dispersion in the surroundings. This, of course, happens in the dumping grounds, as we said, but if we think of our day to day we can think of the plastic bags we use for the rubbish so that it doesn’t scatter around, and we can see that it’s the same idea applied on a reduced scale.
Moreover, the use of plastic avoids useless wastes: the plastic bags of the shopping can be reused as bags for the rubbish, avoiding both a waste of the plastic bag, being thrown away after having used it only once, and an economic saving, since reusing them you can avoid buying the bags for the rubbish.
So, plastic has hundreds of uses in our daily life, some of which are evident, others instead remain more hidden, in little objects or big systems. If we think about all the plastic dkbvt objects we use in our homes, the list could be very long: household electrical appliances, some kitchen tools, pens, bottles, phones and much more, but if we look for what’s out of sight, then we’ll find the pipes in plastic and various kinds of coverings in PVC and similar materials.
Hence, the manufacture of plastic brings to the production of a huge variety of objects thanks to the fact that it’s perfectly deformable when hot, and once it gets cold it keeps the form you gave it. Moreover, it’s colourable, it’s an electric, thermo, acoustic and mechanic insulator, resistant to corrosion and unassailable from moulds.
Depending on the role they will have, the plastic objects will be made of thermoplastic materials, which are deformable when hot and can be lead more than once to high temperature to change their shape, or thermosetting, which can be shaped at high temperature only once: if brought to high temperature for a second time, heat will carbonize them.
