What synthetic polymer is used for garden hoses?
Usually just polyvinyl chloride, which works and is cheap to use.
Does polymer chain length matter?
Yes, polymer chain length does matter as it influences the physical properties of the polymer such as its strength, flexibility, and viscosity. Longer polymer chains generally result in stronger and more rigid materials, while shorter chains may be more flexible and have lower viscosity. The molecular weight of a polymer is directly related to its chain length.
What is the difference between a lattice and a polymer?
A lattice is a regular arrangement of points or nodes connected by lines or edges while a polymer is a large molecule composed of repeating structural units called monomers. In a lattice, the arrangement is fixed and rigid, whereas in a polymer, the structure is flexible and can vary in composition.
What makes PVC more flexible?
PVC can be made more flexible by adding plasticizers, which are molecules that increase the spacing between polymer chains, thus allowing them to move more freely. These plasticizers improve the polymer's flexibility and make it more resilient to bending and stretching. Additionally, the amount and type of plasticizer used can be adjusted to achieve the desired level of flexibility in the PVC material.
What is monomer density of a polymer?
Monomer density of a polymer refers to the concentration of monomer units within the polymer structure, typically expressed in terms of moles per unit volume. It gives insight into how densely packed the repeating units are within the polymer, which can influence the material's mechanical and thermal properties. Higher monomer density often correlates with increased rigidity and strength, while lower density may result in more flexible and elastic characteristics. Understanding monomer density is crucial in polymer chemistry for tailoring materials for specific applications.
What are the purposes of the brake cables and flexible hydrolic brake hoses?
hydralic hoses are easier to seculate fluid
What is the difference between pipe and hoses?
Generally a hose is flexible and a pipe is not. I was laying pipe in your girlfriend last night... whereas she and her friends are hose. I hope that helps.
What synthetic polymer is used for garden hoses?
Usually just polyvinyl chloride, which works and is cheap to use.
What is the purpose of flexible brake hoses?
So they are easier to work around the brakes
How can you make a flexible polymer more rigid?
At the design stage adding molecules/monomers with more rings than chains will make the polymer more rigid. If this option is not available, adding fiber or particles or fillers is the usual technique. You can make a stiff polymer more flexible by adding plasticizers, but going the other way is more difficult. Technically speaking the polymer itself isn't changing, but the material overall will be more rigid than the polymer matrix due to the fiber support.
Does polymer chain length matter?
Yes, polymer chain length does matter as it influences the physical properties of the polymer such as its strength, flexibility, and viscosity. Longer polymer chains generally result in stronger and more rigid materials, while shorter chains may be more flexible and have lower viscosity. The molecular weight of a polymer is directly related to its chain length.
If you add water to a polymer what will happen?
When water is added to a polymer, it can cause the polymer chains to swell and increase in volume. This is because water molecules can interact with the polymer chains, promoting their separation and expansion. In some cases, this can lead to the polymer absorbing water and becoming softer or more flexible.
Why PVC is soft and flexible whereas bakelite is hard and brittle?
PVC is softer and flexible because it is a thermoplastic polymer, which means it can be easily molded and reshaped when heated. Bakelite, on the other hand, is a thermosetting polymer, which means it hardens irreversibly once molded and cannot be reshaped. This makes bakelite hard and brittle compared to PVC.
What is the significance of the Flory characteristic ratio in polymer science and how does it influence the behavior of polymer chains?
The Flory characteristic ratio is important in polymer science because it helps determine the size and shape of polymer chains. It influences the behavior of polymer chains by affecting their flexibility, stiffness, and ability to interact with other molecules. A higher Flory characteristic ratio indicates a more extended and flexible polymer chain, while a lower ratio indicates a more compact and rigid chain.
Why is it a disadvantage for hydraulic systems to have flexible tubes?
If the hoses ("tubes") expand, the pressure available at the working device will be lower, reducing the force available. Also, if the hoses are moving around because they are flexible, they are more likely to get worn or damaged.
