Additives in plastics Additives are added for many reasons some of the additives and its purpose we are going to discuss here. Additives are also called as Agents Before that we get know about the term Polymers why because in this blog the term polymers only used so it’s essential to know what is polymers Polymers: Synthetic Large molecules are made by joining together thousands of small molecular units know as monomers. The process of joining the molecules is called polymerization and the number of units in the long molecule is known as degree of polymerization. The name of many polymers consists of the name of the monomers with the suffix poly. Now your clear about the term polymers, ok now again we come back to the Additives / Agents, types of agents are listed below according to the requirement the additives are used. Antistatic Agents : Most polymers are poor conductors of current build up a charge of static electricity. Antistatic agent attracts moisture from ...

Types of Engineering plastics In last blog I discussed about the types of plastics the main type in its engineering plastics, why because it’s only mostly used in wide range in present life. Thermoplastics only play an important role the engineering plastics are derived as engineering thermoplastics.             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. Many kinds of thermoplastic are used for engineering purpose here I’m going the discuss about most important type of thermoplastics which is used in wide range they are. Acrylonitrile-Butadiene-Styrene (ABS): ABS ( Acrylonitrile-Butadiene-Styrene) is an opaque thermoplastic polymer material made from the monomers Acrylonitrile, 1, 3-Butadiene and Styrene. Strong and durable even ...

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 subjec...

Plastic Definition. Material that can be reshaped or reformed with the influence of Heat and Pressure. Material deforms from its original shape and not able to regain its original shape without any external force those materials are called Plastics. Material which is all having plasticity in nature those materials is called plastic. Plasticity Plasticity is the propensity of a material to undergo permanent deformation under load when compressed. Types of Plastics. 1.       Natural Plastics i)         Bio-Based Plastics ii)       Biodegradable Plastics 2.        Thermoplastics 3.     Thermosets 4.       Engineering Plastics

What is detonation? Detonation : At present the amount of power that can be developed in the cylinder of a petrol engine is fixed by the liability of a fuel to detonate, just before the flame has completed its course across the combustion   chamber and remaining unburnt charge fires throughout its mass spontaneously without external assistance. The result is a tremendously rapid and increase in pressure which sets up pressure waves that hit the cylinder walls with such violence that the walls emit a sound like a ping. It is the ping that   manifests detonation. Thus a very sudden rise of pressure during combustion accompanied by metallic hammer like sound is called detonation. The region in which detonation occurs is farthest removed from the sparking plug , and is named the detonation zone and even with severe detonation this zone is rarely more than one quarter the clearance volume.

What is per-ignition???? Pre-ignition:         Is the ignition of the homogeneous mixture in the cylinder, before the timed ignition spark occurs, caused by the local overheating of the combustible mixture? For premature ignition of any local hot-spot to occur in advance of the timed spark on the combustion stroke it must attain a minimum temperature of something like 700-800 degree centigrade. ·          Pre-ignition is initiated by some overheated projecting part such as the sparking plug electrodes, exhaust valve head , metal corners in the combustion chamber, carbon deposits or protruding cylinder head gasket rim ·          However, pre-ignition is also caused by persistent detonating pressure shock waves scoring away the stagnant gases which normally protect the combustion chamber walls. The resulting increased heat flow through the walls raises t...

First car in INDIA : Germany is the birth place of the automobile. It was invented there, it went through its first paces there and it was developed there to a high level of technical maturity. The list of German automobile pioneers is a long one. Starting with Nicholas cugnot, august Otto, Carl Benz, gottlieb Daimler, wilheln maybach and Rudolf diesel and going all the way up to Ferdinand posche and Felin wankel. First car came to India as an imported car because those days German only leading in car manufacturing those day in India we used only bulk cart for transport purpose and that also used buy rich peoples in those days travelling are very difficult in case of emergency also no other go for people they used to go with the help of horse wagon because compare to bull horse was speed  In India the first motor car appeared in 1897. For about 50 years from 1897, India was an importer of automobiles. The late Bharat Ratna sir M.Vivesvaraya made an automobile in...
