NEWS ON EV FIRE INCIDENTS

 

Now a days we are hearing news about Electrical vehicles caught fire from here and there.

In this regards recently Central Consumer Protection Regulator CCPA on 26/07/2022 said that they had issued notices to four - five Electric vehicles manufacturers about battery explosion of Electrical Vehicles. Chief commissioner of CCPA Nidhi Khare told to reporters about above information.

Replaying to a question in Lok Sabha ,Union Road Transport and Highways Minister Nitin Gadkari

said that show cause letters are issued to all the EV two wheeler manufactures after their two wheelers caught fire due to Battery issues. He also told that based on their received responses further action would be taken.

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

It came from a rubber tree. The official name of the rubber tree is Hevea Brasiliense. Rubber tree was discovered in Brazil. The tree grows only in such conditions where there is a lot of rainfall and simultaneously very hot climatic conditions.

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:

1. Synthetic rubber can be engineered to create rubber with particular performance characteristics.
2. It can be engineered to have built-in cut resistance which is very valuable in treads and sidewalls. 
3. 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?

Oxygen like UV light, can break down rubber molecules, making rubber brittle, causing cracks, and rapid wear. Oxygen in the air can cause this, and Ozone, a special type of Oxygen molecule, is especially hard on tires. So, we add antioxidants and antiozonants.

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.
