How is Nylon manufacturing process?
1. It is manufactured by process of chemical polymerisation into thin fibre/sheet or spun into yarn.
What is condensation polymerisation?
Condensation polymerisation is when two molecules of the same substance (monomer) react together to form polymer chain (like polythene) and eliminate a smaller (usually water) molecule. For example, Nylon-6 is prepared by using condensation polymerisation of ε-Caprolactum
How do expansion joints in a sidewalk keep the concrete from cracking?
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.
What is a loop reactor?
A bulk (slurry) polymerisation reactor which is made of a closed long tube through which the slurry is circulated. Loop reactors are characterised by a very narrow residence time distribution, leading to uniform product characteristics.
What happens when concrete has no steel reinforcement?
The concrete would be weaker, and more prone to cracking.
What are the differences between cracking and polymerisation?
cracking is breaking bonds of the hydrocarbons and polymerisation is making the double bonds between the hydrocarbons. WillyD
What is difference between thermal and catalytic cracking?
Thermal CRacking is caused by heat while catalytic cracking is not caused by heat
Does cracking your knuckles push air out of the joint?
Cracking your knuckles releases the nitrogen from in between your joints.
What are the examples of polymerisation?
polyethylene,polyvinylchloride
Why the polymerisation of benzene is not possible?
it is possible
How is polymerisation carried out?
There are 2 types:- Addition polymerisation is polymerisation in which monomers are joined across the double bond, for example polyethene. Condensation polymerisation is when water is lost from the two monomers for example the polymerisation of nylon, the two monomers are a diamine and dicarboxylic acid. From the amine an H goes and combines with and OH from the acid to form water. From this reaction, 2 moles of water are lostto form nylon -NH-[ ]-NH-C=O-[ ]-C=O-
What is polymerisation reaction?
Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
What technology is used in the manufacturing of polythene?
Polymerisation
What is electropolymerization?
polymerisation in the presence of an electrical current
Who invented computer cracking?
originally computer cracking was to test computer is different situations. previous to that people would use hacking/cracking to fool telephone exchanges to get free phone calls etc
What process joins two monomers?
Addition polymerisation
When monomers join up the process is called?
polymerisation.
