Types of plastics

Types of plastics
Bio-based plastics:
These polymers are synthesized by living organisms, essentially in the form in which they are finally used. Examples of naturally produced bio-based polymers include;
• cellulose / starch
• proteins
• bacterial polyhydroxyalkanoates
after extraction and purification, direct industrial exploitation is possible.
Mainly Used in automotive interior and exterior, consumer electronics and furniture.

Biodegradable plastics:
Biodegradable plastics are plastics that are capable of being decomposed by bacteria or other living organisms.
Two basic classes:
Plastics made from petrochemicals with biodegradable additives which enhance biodegradation
Bio plastics, whose components are derived from renewable raw materials,

Thermoplastics:
A thermoplastic is a type of plastic made from polymer resins that becomes a homogenized liquid when heated and hard when cooled. When frozen, however, a thermoplastic becomes glass-like and subject to fracture. These characteristics, which lend the material its name, are reversible. That is, it can be reheated, reshaped, and frozen repeatedly. This quality also makes thermoplastics recyclable.

There are dozens of kinds of thermoplastics, with each type varying in crystalline organization and density. Some types that are commonly produced today are polypropylene, polyethylene, polyvinylchloride, polystyrene, polyethylenetheraphthalate and polycarbonate.

Thermosets:
Thermoset, or thermosetting,

plastics are synthetic materials that undergo a chemical change when they are treated, creating a three-dimensional network.  After they are heated and formed, these molecules cannot be re-treated and reformed.

Engineering plastics:
Engineering Thermoplastics are a subset of plastic materials that are used in applications generally requiring higher performance in the areas of heat resistance, chemical resistance, impact, fire retardancy or mechanical strength.

Engineering Thermoplasticsare so named as they have properties in one or more areas that exhibit higher performance than commodity materials and are suitable for applications that require engineering to design parts that perform in their intended use

What are the most fascinating science facts?

The blood would appear  green  in color in deep sea/ocean. Water can  boil  and  freeze  at the same time. If you took out all the  empty space  in our atoms, the human race could fit in the  volume of a sugar cube . Lasers can get  trapped  in a waterfall. A  teaspoonful  of neutron star would weigh  6 billion tons . The Eiffel Tower can be  15 cm  taller during the summer. Babies have around  100 more bones  than adults. An egg looks like a  crazy jellyfish  underwater. A flea can  accelerate faster  than the Space Shuttle. A single solar flare can release the equivalent energy of  millions of 100 megaton atomic bombs . Cats always land on their  feet . If you  spin  a ball as you  drop  it ,  it  flies .

FIFA WORLD CUP HISTORY

Image
Federation International The Football Association The success of the Olympic Football Tournament intensified FlFA's wish for its own world championship. Questionnaires were sent to the affiliated associations, asking whether they agreed to the organization of a tournament and under what conditions. A special committee examined the question, with President Jules Rimet the driving force. He was aided by the untiring Secretary of the French Football Federation, Henri Delaunay. Following a remarkable proposal by the Executive Committee, the FIFA Congress in Amsterdam on 28 May 1928 decided to stage a world championship organized by FIFA. Now, the organizing country had to be chosen. Hungary, Italy, the Netherlands, Spain and Sweden submitted their candidatures. Right from the start, Uruguay was the favorite and not simply for its Olympic gold medal wins in 1924 and 1928 - the country was celebrating its 100th anniversary of independence in 1930 at great expense. Moreover, it...

CRANKCASE

http://en.wikipedia.org CRANKCASE         The main body of the engine to which the cylinder are attached and which contains the crankshaft and crankshaft bearings is called crankcase.This members also holds other parts in alignment and resists the explosion and intertia forces.It also protects the parts from dirt etc. In the crankcase only the engine oil are stored in self lubricate syst em the crankcase play an important role the scoop used for splashing to the engive wall are taking oil from the crankcase only so I play a majore role in lubrication system      Crankcase forming an engine block ,crankcase  are the basic engine structural component   crankcase often has an opening in the bottom to which an oil pan is attached a gasketed bolted joint. Material used for crankcase  Material which is used for making crankcase are engine block mostly cast aluminium crankcase are made via sand casting ...
