How to Induce Elasticity in Polystyrene?

Polystyrene is a widely used polymer known for its rigid and brittle nature. It is a widely used polymer in various custom machining industries due to its low cost, easy processability, and excellent electrical insulating properties. 

However, its inherent brittleness has limited its applications in scenarios that require flexibility and resilience.  Thus, there are various techniques and methods available to induce elasticity in polystyrene, making it more flexible and versatile for different applications. 

In this article, we'll explore some effective ways to enhance the elasticity of polystyrene making it suitable for a broader range of uses in custom CNC machining services.

Factors Influencing Elasticity in Polystyrene

Many factors can influence the elasticity of polystyrene. Understanding and manipulating these factors enable the tailoring of polystyrene's mechanical properties to meet specific application requirements.

Molecular Structure and Chain Flexibility

The molecular structure of polystyrene plays a pivotal role in determining its elasticity. Polystyrene is made up of long chains of repeating styrene monomer units. The arrangement and length of these chains influence the material's flexibility and ability to return to its original shape after deformation. 

Long, linear chains can hinder movement and reduce elasticity, while introducing branches or incorporating more flexible monomers can enhance chain mobility and increase elasticity.

Temperature and Thermal Properties

Temperature has a significant impact on the elasticity of polystyrene. At higher temperatures, the kinetic energy of polymer chains increases, allowing them to move more freely and making the material more elastic. 

However, extreme temperatures can lead to thermal degradation, reducing elasticity. The glass transition temperature (Tg) is a critical point for polystyrene. Above Tg, the material transitions from a rigid, glassy state to a rubbery state, increasing its elasticity.

Elasticity Inducing Techniques for Polystyrene

1. Annealing and Heat Treatment Techniques

Annealing and heat treatment are techniques commonly used to induce elasticity in polystyrene. By manipulating its molecular arrangement and reducing internal stresses you can get better quality for custom machining.

Annealing

Annealing involves subjecting a material to controlled heating and controlled cooling cycles in order to alter its internal structure and relieve stresses. In the case of polystyrene, annealing can help increase its elasticity by allowing the polymer chains to relax and reorganize themselves.

1. Heating Phase: Polystyrene samples are heated to a temperature slightly below its glass transition temperature (Tg). This allows the polymer chains to become more mobile and enables them to move and rearrange.

2. Holding Phase: The material is held at this temperature for a specific period, allowing the polymer chains to adjust their positions and relieve internal stresses that may have developed during processing or deformation.

3. Cooling Phase: After the holding phase, the samples are gradually cooled to room temperature. During this cooling process, the polymer chains become locked in a more relaxed and organized state, which contributes to improved elasticity.

Heat Treatment

Heat treatment involves subjecting polystyrene to higher temperatures for a specific duration to induce changes in its molecular structure, crystallinity, and mechanical properties. 

This process can lead to improved elasticity by promoting the rearrangement of polymer chains and increasing chain mobility.

1. Heating Phase: Polystyrene samples are heated to a temperature above its glass transition temperature or even slightly above its melting temperature. This allows the polymer chains to move more freely.

2. Holding Phase: The material is held at the elevated temperature for a specific period to ensure sufficient molecular rearrangement and relaxation of stresses.

3. Cooling Phase: The samples are gradually cooled down to room temperature or below. The slow cooling helps maintain the changes induced during the heat treatment.

Both annealing and heat treatment help reduce internal stresses and allow the polymer chains to regain a more relaxed and organized state, resulting in improved elasticity. Also, these processes can lead to increased ductility and toughness, making the material more resistant to deformation and better able to recover its original shape.

2. Incorporation of Elastomers or Rubber Modifiers

Elastomers are polymers with a high degree of flexibility and the ability to return to their original shape after deformation. When these elastomers or rubber modifiers are blended with polystyrene, they create a sophisticated composite material. This material combines the rigidity of polystyrene with the elasticity of rubber, resulting in improved overall elasticity for custom CNC machining.

1. Selection of Elastomer: Choose an appropriate elastomer or rubber modifier that complements the desired mechanical properties of the final material. Common elastomers used with polystyrene include polybutadiene and styrene-butadiene rubber.

2. Blending: Mix the chosen elastomer with polystyrene through a process such as melt blending. This can be done using techniques like extrusion or compounding, ensuring thorough distribution of the elastomer throughout the polystyrene matrix.

3. Processing: The blended mixture is then processed using conventional methods like injection molding, extrusion, or compression molding to shape the material according to the desired form and application.

The presence of elastomers imparts greater flexibility and elastic behaviour to the polystyrene matrix, allowing it to deform under stress and recover its original shape upon release. Besides, elastomers can significantly increase the material's impact resistance and ability to absorb energy, making it less prone to fracture or breakage.

3. Copolymerization with Other Monomers

Copolymerization involves the simultaneous polymerization of two or more different monomers to create a polymer chain that combines the properties of both. By copolymerizing polystyrene with a more flexible monomer, the resulting copolymer can exhibit increased elasticity. It also leads to retaining some of the polystyrene's other desirable properties for custom cnc service.

1. Monomer Selection: Choose a suitable monomer to copolymerize with styrene. Monomers that introduce flexibility and elasticity, such as butadiene, can be selected.

2. Copolymerization: The selected monomer is polymerized alongside styrene using suitable catalysts and reaction conditions. The resulting polymer chain consists of alternating segments of both monomers.

3. Tailoring Properties: The ratio of styrene to the flexible monomer can be adjusted to control the degree of elasticity and other mechanical properties in the final copolymer.

By adjusting the monomer ratio and polymerization conditions, it's possible to fine-tune the material's mechanical properties to match specific application requirements. The copolymer can still retain some of the inherent strength and rigidity of polystyrene while gaining elasticity.

4. Plasticization and Utilization of Plasticizers

Plasticization involves incorporating specific additives called plasticizers into the polystyrene matrix. These plasticizers interact with the polymer chains, reducing the forces between them and promoting greater mobility. This results in improved flexibility and elasticity of the material used in producing cnc machining parts.

1. Plasticizer Selection: Choose a suitable plasticizer based on its compatibility with polystyrene and its ability to reduce intermolecular forces. Common plasticizers include phthalates, adipates, and citrates.

2. Addition and Mixing: The chosen plasticizer is added to polystyrene and thoroughly mixed. This can be done through processes like melt blending or solution mixing.

3. Plasticization: Plasticizers penetrate between the polymer chains, creating space and reducing intermolecular forces. This enables the chains to move more freely, increasing the material's flexibility and elasticity.

The amount and type of plasticizer added can be adjusted to achieve the desired level of elasticity while maintaining other mechanical properties. Plasticized polystyrene gains improved toughness and impact resistance due to its enhanced ability to absorb energy.

Conclusion

Incorporating elasticity into polystyrene opens up a world of possibilities for its applications across various industries including custom machining. Annealing, heat treatment, elastomer incorporation, copolymerization, and plasticization are effective methods to enhance the polymer's flexibility and resilience. By carefully selecting and combining these techniques, manufacturers can tailor polystyrene properties to meet specific requirements.

What is grid north?

True north changes throughout time, but magnetic north is stable in one place. Moreover, true north is a fixed place on the Earth whereas magnetic north is the direction in which the compass needle points in. Grid north is a term similar to these two. Map users need to understand these three types of the north. In this article, you can check about the grid north.   

Definition of grid north

The grid north is a navigational phrase used to refer to the northward on a grid line in a map projection. The grid north differentiates the true north and magnetic north in that it is aligned to grid lines and always points upwards on a map. The grid lines from the grid north subdivide the UK into squares one kilometre, east of the Atlantic ocean's imaginary point. The line points towards the grid north and has a slight variation from the true north. Some navigators ignore the difference between grid north and true north because of the slight differences. 

What is magnetic north?

Magnetic north remains constant at a particular location, while true north shifts with time. Moreover, magnetic north is the direction pointed out by the compass needle and true north is a permanent location on the Earth. 

Magnetic north definition

Magnetic north is the direction a magnetic compass would point at the time the map was published. The direction of magnetic north varies over time and with the position on the surface of Earth. Thus, magnetic declination values on the old maps are no longer accurate. 

In other words, the north direction in the magnetic field of Earth is indicated by the north pole of a compass needle. 

What is true north?

True north changes with time, whereas magnetic north, keeps the same at a fixed point. Also, true north is some fixed point on the globe, and magnetic north is the direction the compass needle points out. Let us check the definition and what is the true north below. 

True north definition

True north also called geographic north is the direction of the line of longitude that intersect the quadrangle. All the longitude lines converge to points at the north and south poles. 

In other words, true north, as opposed to magnetic north, is determined by drawing an imaginary line through the Earth.

True North Vs Magnetic North

The main difference between true north and magnetic north is caused by the magnetic field of the earth, which is constantly shifting. True north changes over time, while magnetic north remains the same. Let us have a deep insight into the comparisons and differences between the True north Vs Magnetic north in this article.  

True North Vs Magnetic North 

• True north is the intersection of the Earth's surface with the axis of rotation. Magnetic north is where Earth's geodynamo determines at that point in time. 
• True north is a fixed point on the globe. Magnetic north is the direction that the compass needle points to as it aligns with the magnetic field of Earth.

• An exhaust brake connects to the exhaust system, whereas a Jake brake connects to the valve train.
• The jake brake has significantly higher breaking power than the exhaust brake.
• Jake brake is noisier than the exhaust brake.
• Jake brake is more expensive than exhaust brake. 
• The efficiency of the exhaust brake is less compared to the jake brake. 
• Jake brakes are more effective than jake brakes for slowing down the car. 

Summary 

An exhaust brake slows the engine by increasing pressure, whereas a Jake brake slows the engine by lowering pressure. An exhaust brake links to the exhaust system, whereas a Jake brake connects to the valve train. A Jake brake offers far more braking power than an exhaust brake.

A Jake brake is noisier than an exhaust brake. Both brakes are required for large vehicles, but they serve unique duties. If you're in the market for a new car or need service on your current one, consult with a professional to determine which type of brake is best for your needs.

Challenges for the EV Infrastructure Industry

Electric vehicles (EVs) have gained considerable momentum in recent years as a viable alternative to traditional fossil fuel-powered cars. An EV is a vehicle which is powered by an electric motor that gets electricity from a battery and is capable of being charged from an external source.

However, the adoption of electric vehicles is not without its challenges. One of the most significant obstacles to the widespread adoption of electric vehicles is the lack of sufficient EV infrastructure.

In this article, we will discuss some of the challenges facing the development of EV infrastructure. 

Limited charging infrastructure: One of the biggest challenges facing the growth of the electric vehicle market is the limited charging infrastructure. EVs require frequent charging, and without a reliable network of charging stations, EV owners may face difficulty finding places to charge their vehicles. While some companies have installed charging stations in public places like shopping malls, parking lots, and gas stations, the overall number of charging stations is still relatively low compared to the number of gas stations. To encourage EV adoption, governments need to invest in the development of a robust charging infrastructure.

High cost of charging stations: Another significant challenge facing the development of EV infrastructure is the high cost of installing charging stations. Building a charging station requires significant investment, and the high cost of installation is a significant deterrent for businesses and individuals looking to invest in EV infrastructure. However, as more companies and individuals realize the benefits of owning and driving electric vehicles, the demand for charging stations will increase, and the costs associated with installing them will likely decrease.

Range anxiety: It is a term used to describe the fear of running out of power while driving an electric vehicle. Unlike traditional gasoline-powered cars, EVs have limited driving ranges, and if the battery runs out, the driver may be stranded until they can find a charging station. This fear can be a significant barrier to adoption for some consumers, who are used to the convenience of being able to refuel their cars at any gas station. However, advances in battery technology have led to longer ranges for electric vehicles, and this is gradually reducing the impact of range anxiety on potential EV buyers.

Lack of standardization: Another challenge facing the development of EV infrastructure is the lack of standardization in charging technology. There are currently multiple types of charging stations available, and different vehicles require different types of charging connections. This lack of standardization can create confusion and inconvenience for EV owners, who may struggle to find the right charging station for their vehicles. However, efforts are underway to develop a standardized charging system that will make it easier for EV owners to charge their vehicles regardless of the make and model.

Electric Vehicle Infrastructure Market

As per RationalStat’s market study, India electric vehicle infrastructure market, is expected to experience a robust growth rate of 30% between 2019 and 2028. The infrastructure to charge an electric vehicle is crucial for India's growth. India's Government has set a goal to make 70% of all commercial vehicles, 30% of private cars and 40% of buses and 80% of two-wheelers changes to EV by 2030. To achieve this goal, India must have enough charging stations.

The EV market is growing because of rising concerns about urban air pollution. Conventional fuel vehicles are a major cause of air pollution. This forces governments to impose strict regulations on car manufacturers to limit vehicle emissions. EVs are able to reduce dependence on oil-based fuels, and significantly reduce greenhouse gas emissions. The government of many countries are also involved in driving the EVs’ sales by providing subsidies for customers.

Future Growth of Electric Vehicles

The Federation also requested FAME-II of the Indian Chambers of Commerce & Industry to continue until 2025 to increase the EV demand. The scheme cost US$ 1.3 billion to finance the incentivized EV purchase and help India's charging infrastructure. In 2018, the National E-Mobility Program, which was designed to promote hybrid and electric vehicles in India, was launched. It aimed at achieving national fuel security. The program aims to reach 30% of all-electric vehicles by 2030. This will be a major boost to market growth in the future.

Bottom Line

The development of EV infrastructure is crucial for the growth and adoption of electric vehicles. The challenges facing the development of EV infrastructure include limited charging infrastructure, high costs of charging stations, range anxiety, and lack of standardization. However, with the right investment and collaboration between the public and private sectors, these challenges can be overcome, and electric vehicles can become a viable alternative to traditional gasoline-powered cars.

Difference between elastic and inelastic collisions

An elastic collision is a state where there is no net loss in kinetic energy in the system as a result of the collision. An inelastic collision is a state where there is a loss of kinetic energy as a result of the collision. In an inelastic collision, the loss of kinetic energy is transformed into thermal energy, sound energy, and material deformation. You can check out the difference between elastic and inelastic collision in this article below. 

Difference between elastic and inelastic collisions

• The total kinetic energy is conserved in elastic collisions. The total kinetic energy of bodies at the beginning of the collision is different in inelastic collisions. 
• The momentum does not change in elastic collisions as well as inelastic collisions. 
• No conversion of energy takes place in elastic collisions. The kinetic energy is changed into other energy such as sound or heat energy in case of inelastic collisions. 
• An elastic collision is highly unlikely in the real world as there is almost always a change in energy. An inelastic collision is a normal form of collision in the real world.  
• The particles in a perfectly inelastic collision stick together after the collision, whereas the particles in an inelastic collision do not stick together and move individually.
• Examples of elastic collisions: Swinging balls OR Spacecraft flying near a planet but not affected by its gravity. Examples of inelastic collisions: Collisions of two cars OR A bat striking a baseball.
