What is a
Tire?
Geometrically Tire is a three-dimensional circle.
Definition
of a Tire?
The name of the Tire came from
What are
the Main Functions of a Tire?
The main functions of a tire are supporting vehicle load, Absorbing the shocks in the road, direction, Acceleration and braking.
What are
the Major Ingredients of a Tyre?
The major ingredients are natural rubber, Synthetic rubber, carbon
black, steel, anti-oxidants, sulfur, wax, accelerator. etc.
Where
does natural rubber come from
How does
one get the rubber out of the tree?
It can be obtained by a process called Tapping. Tappers use
a special curved knife to gently shave a thin layer of bark from the rubber
tree. Tapping is a very skilled job. Too deep and it wounds the tree. Too
shallow and the rubber won’t leach.
After tappers shave the bark, the latex which looks like a
cross between household glue and whole milk, oozes from the spiral cut, down a
spout, and into a collection pot. It takes 3 to 4 hours to produce a little
less than one pot before the latex stop flowing. Trees are tapped every other
day or every third day. Trees are six to seven years old before they are tapped.
Each tree can produce latex for up to 32 years, depending on how after they are
tapped.
Advantages
of using natural rubber in tires: -
1. Natural rubber lasts a long time and tends to
run cool especially under heavy loads.
2. It also has very high tensile strength, which
means the tire can easily withstand repeated flexing and can still spring back
to its original shape.
3. It also offers excellent tearing resistance,
because of that quality it is wildly used in /off-highway where the tire tread
compound requires cut, chip, and tear fighting for longer tire wear.
4. Natural rubber is often used in the casing,
especially where the bonds must be maintained between the steel cording and the
rubber.
Dis - Advantages
of using natural rubber in tires:
1.
It cost high.
2.
It performs badly in wet traction tests and wears
uneven tread surface.
3.
With natural rubber, we pretty much have to take
what we get.
Advantages of using Synthetic rubber in tires:
- Synthetic rubber can be
engineered to create rubber with particular performance characteristics.
- It can be engineered to
have built-in cut resistance which is very valuable in treads and
sidewalls.
- It can be engineered for
irregular wear resistance and also for excellent wet traction.
What is Carbon
block?
It is a very important filler in tire rubber and makes up 30
% of the tire. It is very finely powdered, very pure carbon, a bit like the
soot that forms on the inside of an oil lamp. It adds enormous strength to the
tire. Rubber reinforced with carbon black. It is stronger, wears more slowly,
and is easier to process. It also helps protect rubber against Ultraviolet (UV)
light from the sun. Carbon block tends to shields rubber molecules from UV
light, like sunscreen.
How much
quantity of Steel is in a modern-day tire?
At about one-fifth of the tire by weight. Steel is the major
component for the beads, belts, and body. Just as the carbon block acts as a
sort of “rebar” for the concreate of the rubber, the steel cord in a radial tire
acts a bit like the steel frame of a modern building. Different kinds of steel,
different diameters of steel wire, and different types of cable are engineered
for specific purposes.
Why is
the cable golden color?
Normally rubber and steel don’t stick together very well,
and that’s essential in a radial tire. There is a special coating on each
strand to help it adhere to the rubber in the tire. The coating is tightly
bonded to the wire, and in turn, bonds tightly to the rubber during processing.
What is
the role of sulfur in a tire?
It is one of the most important vulcanizing agents. During
cooling, sulfur atoms connect different rubber molecules, effectively making
several smaller molecules into one big one.
What is
the role of anti-oxidants & antiozonants in a tire?
What is
the role of accelerators in a tire?
Different kinds of rubbers are used during the manufacturing
process based on the functions they have to perform in a tire. But they all
have to be cured together, in the same amount of time during the curing
process. Accelerators help control the speed of the cure, so everything ends up
fully cured, without having to spend excessive time in the mold.
What is
vulcanization and what is its importance in a tire manufacturing process?
Vulcanization is a process of,
as it comes from the
tree, rubber is not very useful. It is a liquid called” latex”, and a bit like
milk or egg whites. Expose latex to alcohol, saltwater, or smoke and it coagulates,
somewhat like cheese. It’s rubbery, and you could compress it into erasers, but
it doesn’t have much more use. Uncured rubber consists of many very long,
stringy molecules, mixed. These molecules consist of carbon and oxygen.
